1986 Formula One World Championship
1986 Formula One World Championship
from Wikipedia

Alain Prost (pictured in 1985) won his second consecutive Drivers' Championship, driving for McLaren.
Nigel Mansell, driving for Williams, finished runner-up to Prost by two points after dramatically retiring from the final race.
Mansell's Williams teammate Nelson Piquet (pictured in 1990) finished third, three points behind Prost.
McLaren-TAG finished runner-up in the Constructors' Championship with the McLaren MP4/2.
Lotus-Renault finished third in the Constructors' Championship with the Lotus 98T.

The 1986 FIA Formula One World Championship was the 40th season of FIA Formula One motor racing. It featured the 1986 Formula One World Championship for Drivers and the 1986 Formula One World Championship for Manufacturers, both of which commenced on 23 March and ended on 26 October after sixteen races. The Drivers' Championship was won by Alain Prost,[1] Prost was the first driver to win back-to-back Drivers' Championships since Jack Brabham in 1959 and 1960. Together with Prost, Nigel Mansell, Nelson Piquet and Ayrton Senna dominated throughout the season and formed what was dubbed as the "Gang of Four".[2][3] The 1986 season also marked the final Formula One season of 1982 Drivers' Champion Keke Rosberg who retired from the sport at the end of season following a difficult season with McLaren.

After 1986, Renault left the sport as an engine supplier due to company restructuring, only to return in 1989. The Constructors' Championship was won by Williams-Honda. Honda became the first Japanese engine supplier to win a Constructors' Championship.[4]

Team changes

[edit]
Benetton Formula made their entrance in F1.
  • Two factory-backed constructors left Formula One after the 1985 season: Renault (only staying one more year as an engine supplier) and Alfa Romeo. Two other teams had already folded during the season: RAM and Spirit.
  • The Toleman team was bought by the Benetton Group and renamed Benetton Formula.
  • Shortly before the season began, Frank Williams was involved in a road accident in France that left him in a wheelchair. Technical director and part-owner Patrick Head would be forced to run the team in all departments, in addition to his design and engineering work.

Mid-season changes

[edit]
  • When entering the sport in 1985, Haas Lola encountered delays in the development of their first car, and the specially developed Ford-Cosworth V6 turbo was not ready either. So their first chassis was adjusted to be powered by a four-cylinder Hart turbo engine and could only make its debut in September. It was not until the third race of 1986 that the team could get delivery of the Cosworth engine and switch to their second car, specifically designed around it.
  • The small French constructor AGS made their debut in the Italian Grand Prix. Their track record from F2 and F3000 was not particularly promising and the team had no more than seven employees. Their first F1 car existed of as many Renault parts as was legal, bolted onto an F3000 chassis. It was powered by a well-used Motori Moderni engine and driven by Ivan Capelli, while he was still on his way to become International F3000 champion.[5]

Background

[edit]

Back in 1980, Renault proved that turbocharged engines were the way to success and by the half-way point in the 1985 season, all teams had followed their example. The FIA saw that the power output from turbo engines had doubled in the past six years. The 1986 F1 cars in qualifying trim proved to be the most powerful Grand Prix cars in history. Manufacturers mentioned numbers above 1,400 bhp (1,000 kW), powering cars that weighed just 540 kg (1,190 lb) giving a staggering power-to-weight ratio of 2,500 hp/ton.[3] This power output was only seen in qualifying trim, since the specially prepared engines, tyres and gearboxes could only hold on for two to four laps under this immense force before destroying themselves,[16] and in race trim, with the engines limited in power to conserve them to run a 190-mile (306 km) race distance, the cars were not much slower.

So after mandating turbocharged engines for 1986, the governing body decided to re-allow naturally aspirated engines for 1987, and at the same time started reining in the power of turbo engines, before banning them altogether for the 1989 season.[17][18]

Technical regulations

[edit]
  • 1.5 litre turbocharged engines compulsory (with unlimited number of cylinders, RPM and power output).[19][20]
  • Fuel use during the race was limited from 220 L (58 US gal) to 195 L (52 US gal). This led to fuel saving playing a major role in team strategy during the season.[20][21]

Event regulations

[edit]
  • Catch-fencing was banned.[20]
  • After the accident and death of Elio de Angelis in testing, a permanent team of professional firefighters, FIA medical service inspector and medevac helicopter were made mandatory at all testing and race events.[20]

Season report

[edit]

Race 1: Brazil

[edit]

The first race of the season was in Brazil at the rough and abrasive Jacarepagua Riocentro Autodrome in the tropical heat of Rio de Janeiro. Lengthy test sessions there before the race weekend was often the case for the teams. Qualifying resulted in pole position for Senna, followed by the two Williams-Hondas of Nelson Piquet and Nigel Mansell, and by Rene Arnoux and Jacques Laffite in the two Ligier-Renaults. Sixth on the grid went to Michele Alboreto (Ferrari) ahead of Rosberg, Stefan Johansson (Ferrari) and Prost, with Riccardo Patrese completing the top 10 for Brabham.

The race day was very hot and humid. At the start Mansell tried to get ahead of Senna. The Brazilian refused to give way and Mansell went off into the barriers. Piquet then went past Senna on Lap 3 and took the lead, beginning to pull away at a second a lap; Senna remained ahead of Arnoux, although the Frenchman was soon overtaken by Alboreto. Rosberg was fifth but his engine would soon fail, leaving Johansson to take over. Prost made rapid progress and by lap 16 he had worked his way ahead of Johansson, Arnoux and Alboreto and was running third. On lap 19 Piquet pitted for new tyres and on the following lap Prost overtook Senna to go into the lead. Senna pitted, and dropped down the order. Piquet now charged back and retook the lead just before Prost stopped for tires and so the order settled again with Piquet leading Senna and Prost, although the McLaren driver soon went out with an engine failure. This put Arnoux third but he was a long way back and had Laffite on his tail while Dumfries was fifth. The Scotsman then ran into trouble with an electrical problem and pitted. Senna's tires were put on his car and then taken off again and he was sent on his way, with the electrical problem not having been fixed. Berger thus moved into fifth place. Both leaders pitted again but the order remained unchanged and Rio native Piquet duly won the race with São Paulo native Senna second, completing a Brazilian 1–2 at the Brazilian Grand Prix. Laffite got the better of Arnoux for third place, while fifth place went to Brundle, who had overtaken a troubled Berger in the closing laps.

Race 2: Spain

[edit]

3 weeks after the Brazilian Grand Prix saw the return of the Spanish Grand Prix. There had not been a Spanish Grand Prix since the Madrid-based Jarama circuit hosted the race in 1981, but the local authorities in Jerez had built a new circuit and so the F1 trucks rolled down to southern Spain for the event. The circuit, located 1 hour south of Seville was in a desert and was located in the Costa del Sol, providing very pleasant weather for the event. The flat circuit was very modern, and had a number of long corners.

At the start, pole-sitter Senna took the lead and with Piquet second and Rosberg and Prost quickly getting ahead of Mansell. The Englishman then began to charge and he moved gradually back up to second place and on the 39th lap he overtook Senna to take the lead. Mansell then pulled out a four-second lead by Senna gradually reeled him in again, while Prost sat on his tail in his McLaren-TAG/Porsche, Piquet having gone out with engine trouble. With 10 laps to go Senna challenged for the lead but Mansell held him off. Senna was not going to be beaten and tried again at the hairpin at the back of the track. This time he made it through and Mansell had to lift off, which allowed the canny Prost to sneak into second place. Mansell decided to go for a desperate gamble. He pitted for fresh tires, emerging 20secs behind Senna with nine laps to go. Those were mighty laps as Mansell carved into Senna's lead at a rate of four seconds a lap. But ahead of him on the road was Prost – and he was not going to give up without a fight. Mansell was able to pass Prost but he was 0.7s slower on that lap than Senna. Mansell took up the chase again and as they set off on the last lap the pair were separated by only a second and a half. At the hairpin Mansell was right with Senna but there was nothing he could do through the next few corners. It was all going to be down to the acceleration out of the last corner. The Williams-Honda was quicker but Senna got to the line first, the two cars side by side, separated by 0.014secs. It was the second closest finish in F1 history to that point, behind only the 1971 Italian Grand Prix. Prost was third with Rosberg fourth, Fabi fifth and Berger sixth.

Race 3: San Marino (Imola, Italy)

[edit]

The San Marino Grand Prix, not held in the tiny principality of San Marino (which did not have a race track) but at the Autodromo Dino Ferrari in Imola, Italy; just outside of Bologna near the Ferrari headquarters. The circuit had been updated with new safety features, including the demolishing of a house for more runoff area at the fast corner near the two Rivazza corners. Senna was on pole ahead of the two Williams-Hondas of Nelson Piquet and Nigel Mansell. The McLaren of Alain Prost was ahead of Michele Alboreto's Ferrari with Keke Rosberg (McLaren), Stefan Johansson (Ferrari) and the Ligier-Renault of Rene Arnoux next up. The top 10 was completed by the Benetton-BMWs of Gerhard Berger and Teo Fabi while Patrick Tambay was 11th in his Lola-Hart. The Imola circuit was the most demanding circuit of the year for fuel consumption, and this race was to be a real test of patience and strategy for the teams and drivers. Senna took the lead at the start with Piquet behind him but Mansell had an engine problem and dropped back behind Prost and Rosberg. On the fourth lap Prost and Rosberg both overtook Senna but then Rosberg passed his teammate to take second place. Alboreto was fourth while Senna disappeared with a wheelbearing failure. This meant that Fabi and Berger were fifth and sixth, although the Austrian soon overtook the Italian. During the pit stops Prost's crew did a better job and he took the lead when Rosberg pitted on lap 33. Keke's stop was slow and he rejoined second. The order then settled with Piquet having to watch his mirrors for Alboreto while he conserved fuel. Finally he had enough fuel to race again. Alboreto faded and disappeared later with a turbo problem. Piquet caught Rosberg but the McLaren seemed to be able to hold him off until Rosberg ran out of petrol. Riccardo Patrese, up to fourth in his Brabham, also stopped and this meant that Gerhard Berger found himself in third at the finish behind Prost and Piquet. Johansson was fourth with Rosberg and Patrese classified fifth and sixth.

Race 4: Monaco

[edit]

There was a new chicane at Monaco, the track having been extended out over the harbor to create a much slower kink than had previously been the case. The only change to the entry was that Patrick Tambay had a new Ford turbo engine in the back of his Beatrice Lola for the first time. Qualifying resulted in pole position for Prost, with Mansell, and Senna behind him. Then came Michele Alboreto's Ferrari and the improving Benetton-BMW of Gerhard Berger. The Brabham-BMW BT55 seemed to be getting better as well with Riccardo Patrese sixth ahead of Jacques Laffite's Ligier-Renault, Tambay, Rosberg and Martin Brundle in the Tyrrell-Renault. The biggest surprise in qualifying was Johnny Dumfries's failure to qualify the second Lotus-Renault. Laffite had to start from the back of the grid because he was not ready when the field set off for the final parade lap. The start was incident free and the top 10 then remained unchanged for the first few laps with Prost leading Senna, Mansell, Alboreto, a fast-starting Rosberg and Berger. The Austrian fell behind Patrese on lap 10 and on lap 16 Rosberg overtook Alboreto. He followed this up by overtaking Mansell on lap 26 and the Englishman then pitted for new tires, which dropped him to fifth behind Alboreto. Patrese blew his chances by stalling during his pit stop. When the pits stops were over Prost led Rosberg and Senna. Mansell was fourth. Alboreto retired with a turbo failure and Berger went out with a hub problem. Further back there was a dramatic accident when Brundle and Tambay collided at Mirabeau, the Beatrice Lola barrel-rolling in mid-air into the barriers. Both cars were out. The order at the front did not change, however, and so Prost won from Rosberg with Senna third, Mansell fourth and the Ligiers of Arnoux and Laffite fifth and sixth.

Death of Elio de Angelis

[edit]

In the fortnight between Monaco and Belgium, there was a test at Paul Ricard and a rear wing failure on his Brabham caused Elio de Angelis to crash. The car cartwheeled over the barriers and landed upside down. The ill-equipped marshals were unable to turn it over and a fire broke out. This was put out and de Angelis was released and, after a lengthy wait for a helicopter, he was flown to hospital in Marseille where he died of smoke inhalation. This was an incident that led to the introduction of new safety standards for F1 tests but the sport had again lost one of its leading names. The Brabham team decided to run only Riccardo Patrese for the Belgian race.

Race 5: Belgium

[edit]

The Belgian Grand Prix at Spa-Francorchamps saw a big surprise in qualifying as Gerhard Berger qualified his Benetton-BMW second behind Nelson Piquet's Williams-Honda. The powerful and aerodynamically efficient Benetton was able to show its true performance at Spa. Alain Prost was third in his McLaren ahead of World Championship leader Ayrton Senna. Nigel Mansell was fifth in his Williams-Honda with Teo Fabi (Benetton), Rene Arnoux (Ligier-Renault), Keke Rosberg (McLaren), Michele Alboreto (Ferrari) and Patrick Tambay (Lola-Ford) completing the top 10.

Piquet made a good start to take the lead to go into the lead while Berger was slow away and found was between Senna and Prost at the hairpin. Prost and Berger collided and there was chaos behind them. When the dust settled Tambay was out with a broken suspension but everyone else was still going, albeit with some damage. This meant that Piquet was clear of Senna with Mansell third, Stefan Johansson (Ferrari) fourth, Johnny Dumfries (Lotus) fifth and Jacques Laffite (Ligier) sixth. Mansell quickly overhauled Senna but on lap five he spun and was overtaken by Senna and Johansson. Dumfries spun off and so Alboreto moved to fifth having passed the Ligiers, Arnoux having overtaken Laffite. Arnoux's race would end soon afterwards with a blown engine. Soon afterwards Piquet disappeared with another engine failure and so Senna went into the lead with Mansell closing in. The pit stops resulted in Mansell getting ahead of Senna with Alboreto third and Johansson fourth. Senna closed in on Mansell but after a battle the Briton in his better-suited Williams-Honda pulled away to win. Senna was second while the two Ferraris battled for third, Johansson eventually coming out ahead of Alboreto. Laffite was fifth with Prost salvaging one point for sixth place, driving a chassis that according to McLaren technical director John Barnard was badly bent from the accident at La Source and had to be written off after the race.

Race 6: Canada

[edit]

Before the Canadian Grand Prix at the public road Gilles Villeneuve circuit in Montreal, the death of Elio de Angelis a month earlier had created an opening at Brabham and the team hired Derek Warwick who had been left out of work after Ayrton Senna refused to have him as his Lotus teammate. Marc Surer was also missing having been very seriously injured while competing on the Hessen Rally in a Ford RS200 supercar; he never raced in Formula One again. Christian Danner was hired by Arrows but because of contractual problems had to race in Canada for Osella and so there was only one Arrows.

Qualifying resulted in pole position for Nigel Mansell's Williams-Honda with Ayrton Senna's Lotus-Renault right with him. Nelson Piquet was third in the second Williams while Alain Prost was fourth for McLaren ahead of Rene Arnoux (Ligier), Keke Rosberg (McLaren), Gerhard Berger (Benetton), Jacques Laffite (Ligier), Riccardo Patrese (Brabham) and Warwick. Michele Alboreto was 11th in his Ferrari. In the morning warm-up Patrick Tambay suffered a suspension failure on his Lola-Ford and injured his feet in the resulting accident and so he did not start. Mansell took the lead and with Senna holding up those behind him, Mansell seemed to be in a very strong position. Behind Senna were Prost, Piquet, Rosberg, Arnoux and the rest. Rosberg soon overtook Piquet. On the fifth lap Prost finally made it ahead of Senna and the Brazilian went wide and was pushed back to sixth behind Piquet and Arnoux. On lap 13 Rosberg overtook Prost for second and four laps later the Finn took the lead. His fuel consumption was too much., however, and so Rosberg had to back off which enabled Mansell and Prost to close up. As they came up to lap former world champion Alan Jones on lap 22 Rosberg left a small gap and Mansell took the lead again. Mansell pulled away to win the race, and Prost retook Rosberg for second place but he then had a slow pit stop caused by a sticking wheelnut and dropped back to fifth. He spent the rest of the race charging back to take second by the finish. Piquet was third with Rosberg fourth having had to slow to conserve fuel in the closing laps while the troubled Senna was fifth and Arnoux sixth.

Race 7: Detroit (US)

[edit]

Bernie Ecclestone had arranged a convoy to travel from Montreal to Detroit, which would take place a week after the Canadian Grand Prix. Detroit was the only 1986 Formula One Grand Prix in the United States; this unpopular race on a very bumpy, rough, tight and angular street circuit lined with unforgiving concrete walls in the middle of downtown Detroit was widely accepted as the toughest and most demanding Grand Prix of the year. With Patrick Tambay recovering from his leg injuries from Canada, the Beatrice Lola team hired Eddie Cheever for the weekend, while Christian Danner transferred from Osella to Arrows to replace the injured Marc Surer and so Canadian Allen Berg took over the second of the Italian cars. Qualifying resulted in another pole position for Senna in his Lotus-Renault, which had the best chassis and suspension and was able to deal with the bumps and roughness of Detroit better than any of the other cars. The two Williams-Hondas of Nigel Mansell and Nelson Piquet were second and third, Rene Arnoux was fourth in the Ligier-Renault ahead of Stefan Johansson's Ferrari and Jacques Laffite in the second Ligier. Then came Alain Prost's McLaren-TAG, Riccardo Patrese's Brabham-BMW, Keke Rosberg's McLaren and Cheever. As was usually the case in Detroit, it was hot and humid, and at the start Senna took the lead with Mansell second under pressure from Arnoux. On the second lap Senna missed a gear and Mansell went ahead, quickly leaving Senna to fight with Arnoux. Mansell was in trouble with brakes, however, and so Senna was soon able to catch him again and on the eighth lap Senna took the lead again. He was also on harder tires than Mansell so he was well placed for a victory. Mansell dropped back behind Arnoux and Laffite. On lap 12, however, Senna had a puncture and had to pit and so there was a Ligier 1–2 with Arnoux leading Laffite for a couple of laps before Jacques went ahead. Mansell was third with Prost fourth, Piquet fifth and Senna sixth. The pit stops got rid of the Ligiers as a competitive force, the team being much slower than the other front-runners and with Piquet and Mansell both slower than they should have been, Senna was ahead again when the stops were over. Piquet then crashed on the straight before the pits and the car was hit by Arnoux, who then tried to keep going and reversed into the path of Thierry Boutsen's Arrows. This left Senna a long way ahead of Prost with Laffite third and closing. Prost had a misfire and could do nothing to stop Laffite taking second before the finish. Fourth place went to Alboreto with Mansell fifth after he had been up an escape road and Patrese was sixth.

Race 8: France

[edit]

Elio de Angelis's fatal accident had led the Paul Ricard authorities to shorten the circuit dramatically and it now cut through on the 2.3 mile (3.8 km) racing school circuit, which took out the high-speed esses where de Angelis had crashed and reduced the length of the Mistral Straight. Patrick Tambay was back in action with the Haas Lola team after missing the Detroit GP because of leg injuries from an accident in Canada. Tambay also had a new engineer, Adrian Newey having been hired from the March Indycar project. In the days before the race, FISA had also announced plans to introduce a new 3.5-liter normally aspirated formula in 1989. Qualifying resulted in another pole position for Senna in his Lotus-Renault with the two Williams-Hondas of Mansell and Piquet second and third. Arnoux was fourth in the Ligier-Renault ahead of Prost's McLaren-TAG/Porsche. Then came Michele Alboreto's Ferrari, Keke Rosberg's McLaren, the Benetton-BMWs of Gerhard Berger and Teo Fabi and Johansson's Ferrari. At the start Alboreto stalled and was left behind while Mansell took the lead from Senna, Arnoux, Berger, Prost, a fast-starting Johnny Dumfries in the second Lotus, Piquet and Rosberg. Fabi collided with Warwick's Brabham during the first lap and both had to pit. On the fifth lap Senna went off at the very fast Signes corner on oil left by Andrea de Cesaris's exploding Minardi-Motori Moderni. The Lotus hit the barriers and Senna was out- which was the same place Senna had crashed at the French Grand Prix the year before. Mansell was left alone at the front with Arnoux second and Berger under pressure from both McLarens. They soon passed the Benetton while later ran into Christian Danner's Arrows and had to pit for repairs. Prost and Rosberg chased after Arnoux and were both ahead of the Ligier by lap 18. Mansell had two tire stops and Prost was briefly in the lead but with new rubber and no fuel problems, Mansell was able to retake the lead on lap 58 and went on to win the race. Prost was second. Piquet was struggling with electrical trouble all afternoon but managed to overtake Rosberg to finish third while the top six was completed by the two Ligiers of Arnoux and Laffite.

Race 9: Britain

[edit]

There was a massive crowd at the British Grand Prix at the challenging Brands Hatch circuit just outside London, with many locals turning out hoping to see home favorite Mansell win. Jacques Laffite was due to equal Graham Hill's record of 176 Grand Prix starts and the popular Frenchman was hoping for a good performance at Brands Hatch as the Ligier-Renault had been very competitive. Williams celebrated the return of team boss Frank Williams to the F1 paddock for the first time since he was paralyzed in a road accident in March. There was considerable action on the engine front with Ligier announcing a three-year deal for 1987-88-89 with Alfa Romeo and Team Lotus negotiating for Honda engines. The entry was unchanged from the French GP and in qualifying the two Williams-Hondas were dominant with Nelson Piquet ahead of Nigel Mansell. Ayrton Senna was third in his Lotus-Renault ahead of Gerhard Berger (Benetton-BMW), the McLaren-TAGs of Keke Rosberg and Alain Prost, Teo Fabi's Benetton, Rene Arnoux's Ligier, Derek Warwick's Brabham and Johnny Dumfries in the second Lotus. Laffite had a bad qualifying and was 19th. At the start Mansell's Williams failed as he went into Paddock Hill Bend. Moments later, the race was stopped following a multiple crash behind him. This was caused by Thierry Boutsen losing control of his Arrows in the midfield. This bounced off the wall into the backmarkers and Stefan Johansson jinked right to avoid it. Laffite was alongside him and the Ligier had to swerve and went head-on into the barrier. Back on the track Boutsen was hit by Piercarlo Ghinzani (Osella) and by Christian Danner (Arrows) and the accident also involved the two Minardis, the two Zakspeeds and Allen Berg's Osella. Laffite was cut from the wreckage of his car and then flown to hospital but with both legs broken at the age of 42, his Formula 1 career was over. Zakspeed driver Palmer, who is a qualified general practitioner, was the first doctor to be on the scene and came in the aid of his fellow competitor.[22] It took nearly an hour and a half before the race was restarted and Mansell (in the spare car) followed Piquet into the first corner with Berger getting ahead of the second Williams in the course of the first lap. Mansell soon retook the Benetton and went after Piquet. Senna was fourth under pressure from Rosberg but the Finn went out soon afterwards with a gearbox failure and so Prost was fifth ahead of Alboreto. Prost pitted early for new tires (his original set having been out of balance) and he dropped back while Berger went out on lap 23 with electrical trouble. On the same lap Piquet missed a gear and Mansell went ahead, to the delight of the British fans. Soon afterwards the third-placed Senna went into the pits to retire with a gearbox problem. The Williams-Hondas battled for the rest of the afternoon but Mansell stayed ahead to win. Arnoux had run third early on but a bad choice of tires meant he had to stop twice and so Prost took the position with Arnoux fourth ahead of the two Tyrrells of Martin Brundle and Philippe Streiff, the Frenchman overtaking Warwick on the last lap as the Englishman had to conserve fuel. This was the last Formula One Grand Prix at Brands Hatch; from 1987 onwards the British Grand Prix would be held at Silverstone.

Race 10: Germany

[edit]

Jacques Laffite's accident at Brands Hatch meant that Ligier needed a new driver and Philippe Alliot was hired to replace him for the German Grand Prix at the very fast and forested Hockenheim circuit. Team Lotus announced that it would be using Honda engines in 1987 with Ayrton Senna being joined by Satoru Nakajima. Arrows had the new A9 chassis for the first time while Keke Rosberg announced that he would be retiring from Formula One at the end of the season and then took pole position for McLaren, ahead of his teammate Alain Prost, the team having benefited from the arrival of new turbochargers. Ayrton Senna was third with Gerhard Berger fourth for Benetton with Nelson Piquet and Nigel Mansell next in their Williams-Hondas. The top 10 was completed by Riccardo Patrese (Brabham-BMW), Rene Arnoux (Ligier-Renault), Teo Fabi (Benetton) and Michele Alboreto's Ferrari. At the start Senna took the lead as the two McLaren-TAGs were slightly slower off the line. This enabled Berger to grab second from Rosberg and Piquet to get ahead of Prost. Further back Alliot made a good start but then knocked Stefan Johansson into a spin, collecting Fabi's Benetton as it went. Johansson and Alliot both pitted at the end of the lap. Rosberg soon took the lead from Senna and Berger was overtaken by Piquet and it was not long before Piquet was ahead of Senna as well. Berger pitted on lap five with an engine problem. While this was going on Piquet closed on Rosberg and took the lead on lap six. Prost was ahead of Senna with Arnoux fifth and Mansell sixth, complaining of poor handling. Things were so bad that Nigel was overtaken by Alboreto and only regained sixth when the Ferrari went out with transmission failure on lap seven. Piquet decided to go for two stops and so pitted early leaving the McLarens running 1–2 ahead of Senna but when they pitted Piquet went ahead again and although he dropped behind them again when he stopped again he was able to overtake both by the finish. On the penultimate lap both McLarens ran out of fuel and so Senna took second place with Mansell third, Arnoux fourth and Rosberg and Prost being classified fifth and sixth.

Race 11: Hungary

[edit]

The World Championship headed behind the Iron Curtain for the first time to the new Hungaroring, outside Budapest, and there was an enthusiastic welcome for the Formula 1 circus. The very modern track was rather twisty and overtaking would be difficult. Traffic was a problem in qualifying but as usual Ayrton Senna was on pole in his Lotus-Renault with Nelson Piquet second in the Williams-Honda ahead of Alain Prost (McLaren-TAG), World Championship leader Nigel Mansell (Williams-Honda) and Keke Rosberg in the second McLaren. The top 10 was completed by Patrick Tambay in the Lola-Ford, Stefan Johansson's Ferrari, Johnny Dumfries in the second Lotus, Rene Arnoux's Ligier and Alan Jones's Lola. There was a vast crowd, estimated to be more than 200,000 on race day and at the start Senna went into the lead while Mansell blasted ahead of Prost and Piquet to grab second place. Piquet soon showed that he was very competitive by passing Mansell for second. Tambay had started well and overtook Prost on the first lap but he was soon repassed by the McLaren and by his teammate Jones. On lap 11 Prost moved ahead of Mansell and a lap later Piquet took the lead from Senna, who fell back towards Prost's McLaren. Alain soon pitted with an electrical problem and this upset Rosberg's race as he pitted for tires at the same time and had to be waved through. McLaren ceased to be a force. This meant that Mansell was third with Dumfries fourth and Berger fifth. In the middle of the race Piquet pitted for tires while Senna stayed out and charged hard and so that when he pitted he was able to rejoin in the lead. The gap came quickly down and Piquet went ahead again and the two cars then ran close together all the way to the finish but Piquet stayed ahead with Senna settling for second and Mansell third. Johansson claimed fourth with Dumfries fifth and Martin Brundle sixth in his Tyrrell. The result meant that there were four men covered by 11 points in the World Championship race: Mansell, Senna, Piquet and Prost.

Race 12: Austria

[edit]

A week after Hungary, the teams were in action again at the fastest circuit of the year, the scenic and spectacular Österreichring in Austria and it was a surprise to see the two Benetton-BMWs on the front row with Fabi two-tenths faster than home favorite Berger; these cars were not only the most powerful cars on the grid with the Brabhams and Arrows cars but also along with the Williams and McLarens among the most aerodynamically efficient cars. Rosberg was third quickest in his McLaren-TAG/Porsche but the good performance from BMW was highlighted by Riccardo Patrese's fourth place for Brabham. Prost was fifth in his McLaren and then came the regular front-runners and World Championship contenders Mansell and Piquet in their Williams-Hondas and Senna in his Lotus-Renault. The top 10 was completed by Michele Alboreto's Ferrari and Derek Warwick's Brabham. Brabham had problems in the warm-up and so Warwick had to hand over his car to Patrese and the Briton was not able to take the start. At the start Berger took the lead from Fabi, Prost, Mansell, Piquet, Rosberg and Senna. The Benettons were highly competitive and pulled quickly away from the field while Senna soon disappeared with electrical trouble. On lap 17 Fabi went into the lead only to have his engine fail and so Berger went ahead again. Prost stopped for new tires and so Mansell moved to second. This became the lead a few minutes later when Berger pitted with an electrical problem. Mansell pitted and so Prost went into the lead while Piquet disappeared with an engine problem. Almost immediately Mansell too went out with a broken driveshaft. This left Prost by himself at the front with the two Ferraris running second and third, with Alboreto ahead of Stefan Johansson. The two Haas Lolas were fourth and fifth with Alan Jones ahead of Patrick Tambay while the final point went to Christian Danner's Arrows.

Race 13: Italy

[edit]

The big news at the Monza Autodrome near Milan was that McLaren designer John Barnard was leaving to join the Ferrari team. The new AGS was in the paddock for the first time with Ivan Capelli driving the Motori Moderni-engined chassis (which was, in fact, an old Renault Sport one with AGS bodywork). This had previously been tested by Didier Pironi. Michele Alboreto was in difficulties having crashed a motorcycle and injured his shoulder. The Osella team had replaced Allen Berg with local rising star Alex Caffi but otherwise the field was as normal. Qualifying resulted in the Teo Fabi taking pole in his Benetton with Alain Prost second for McLaren ahead of Mansell's Williams, Berger's Benetton, Senna's Lotus and the second Williams of Piquet. The top 10 was completed by Derek Warwick (Brabham-BMW), Keke Rosberg (McLaren), Alboreto and Riccardo Patrese (Brabham). Before the start Fabi and Prost both had trouble and while Fabi had to start from the back of the grid, Prost went to his spare car in the pitlane. As a result, the front row was gone and this enabled Berger to take the lead from Mansell on the run down to the first corner. Senna suffered an immediate transmission failure and retired. The result of all of this was that Berger led Mansell, Piquet, a fast-starting Rene Arnoux (Ligier), Rosberg and Alboreto. In the early laps Alboreto moved ahead of Arnoux and the front four then began to pull away from the rest of the field. At the end of the seventh lap Mansell went into the lead and he was followed through by Piquet and Alboreto as Berger backed off to conserve fuel. In the meantime Prost and Fabi were charging up through the field, Prost getting to sixth by lap 18. The McLaren was then black-flagged for an illegal switch of cars. It mattered little because his TAG engine blew soon afterwards. During the tires stops Alboreto spun and glanced a barrier and had to stop for repairs. This dropped the Ferrari out of the battle for the lead. Piquet now charged up to Mansell and took the lead, pulling away to win a dominant victory and moved himself back to second in the World Championship. Mansell's second place meant that he was still five points ahead. Johansson finished third with Rosberg fourth, Berger fifth and Alan Jones sixth in the Haas Lola.

Race 14: Portugal

[edit]

The Portuguese Grand Prix at the Estoril Autodrome near Lisbon was moved to September instead of being held in April. The field was as it had been at Monza except that Allen Berg was back in the second Osella after the car had been driven by Alex Caffi in Italy. Pirelli announced that it was withdrawing from Grand Prix racing at the end of the year and Renault said that it too had decided not to continue supplying F1 engines for the 1987 season. Ferrari had also announced that it had signed up Gerhard Berger to replace Stefan Johansson. Qualifying resulted in another pole position for Ayrton Senna's Lotus-Renault while Nigel Mansell was second fastest in his Williams-Honda with Alain Prost third for McLaren and Berger fourth in his Benetton. Then came Fabi, Piquet, Rosberg, Johansson, Patrese, and Arnoux. At the start Mansell went into the lead and he remained there for the rest of the afternoon to win an impressive victory. Senna followed him and only dropped from second when he stopped for tires in the mid-race. On the last lap, however, he started to run out of fuel and dropped from second to fourth, promoting Prost to second and Piquet to third. The two Ferraris of Johansson and Michele Alboreto picked up fifth and sixth.

Race 15: Mexico

[edit]

It had been 16 years since the last Mexican GP (the country that hosted the football World Cup earlier that year) and the same circuit, now called the Rodriguez Brothers Autodrome in the heart of Mexico City had been completely rebuilt was a shorter circuit than the original but despite resurfacing work it was very bumpy, thanks to Mexico City's geologically active surface. The circuit was located 7,380 feet above sea level- even higher than the Kyalami circuit in South Africa, of which this event was replacing. The only change from the field at the Portuguese GP was that AGS had not made the trip to Mexico. Qualifying was a familiar story with Senna on pole in his JPS Lotus-Renault. Then came Nelson Piquet and Nigel Mansell in their Williams-Hondas with Gerhard Berger fourth in his Benetton-BMW. Next up was Riccardo Patrese (Brabham-BMW) ahead of Alain Prost (McLaren-TAG/Porsche), Derek Warwick in the second Brabham, Patrick Tambay in the Haas Lola, Teo Fabi's Benetton and Philippe Alliot in the Ligier-Renault. The Ferraris were not competitive. Mansell was in the position to win the World Championship if he could score a good result but at the start he made a mess of it and was left at the back of the field. Piquet and Senna were running first and second. Berger was third with Prost fourth. On the seventh lap Prost got ahead of Berger. Mansell charged up through the backmarkers but then had to pit for new tires. The only man not to do so was Berger, who reckoned that he might be able to go the distance on his Pirelli tires. When the other front-runners returned to action they were not able to close on Berger because the Goodyears were blistering in the heat. Piquet had led comfortably until a suspension issue cost him several seconds per lap, and forced 3 pitstops in the last few laps, dropping him from the lead to 4th.

Berger thus took his first Formula 1 victory, followed home by Prost and Senna. Piquet and Mansell were fourth and fifth - Mansell had caught right up to Piquet but was unable to pass his team-mate, who needed the points to retain a mathematical chance of the championship himself, and set the fastest lap of the race in response to Mansell's challenge: while the final point went to Alliot. As the F1 circus headed off to Australia Mansell was still in a dominant position in the World Championship six points clear of Prost and seven ahead of Piquet.

Race 16: Australia

[edit]

The most dramatic and exciting race of the 1980s, the 1986 race in Adelaide saw the showdown of a three-way fight for the World Championship between Nigel Mansell, Alain Prost and Nelson Piquet. Mansell had 70 points, six more than Prost and seven more than Piquet. Prost's McLaren-TAG was no match for the Williams-Hondas – which had lapped the Frenchman at several races – although Alain had collected points all year while the Williams pair fought one another. Mansell was on pole ahead of Piquet and Ayrton Senna (Lotus-Renault). Prost was fourth followed by Rene Arnoux (Ligier), Gerhard Berger (Benetton), Keke Rosberg (McLaren), Philippe Alliot (Ligier), Michele Alboreto's Ferrari and Philippe Streiff's Tyrrell.

At the second corner of the race, Senna forced his way into the lead. Piquet and Rosberg followed him past Mansell and on that first lap Piquet overtook Senna to take the lead. On the next lap Senna dropped behind Rosberg and on lap 4 behind Mansell. Two laps later Prost was also ahead of Senna.

On lap 7 Rosberg overtook Piquet and began to build a lead while a little later Prost got ahead of Mansell and chased after Piquet. On lap 23 Nelson spun. Prost's hopes seemed to evaporate a few laps later when he had a puncture and had to pit. He was back in fourth again. Piquet charged back from his spin, passing Mansell for second place on lap 44 but Prost closed on his two Williams driver and with 25 laps to go all three were running together.

On lap 63 the battle became one for the lead, when Rosberg suffered a right rear tire failure. Mansell was on course for the title when two laps later on the Dequetteville Terrace (Brabham Straight) his left rear tire exploded at 180 mph. Nigel managed to avoid hitting anything, but his championship hopes were over. Williams had no choice but to call Piquet to the pits and so Prost went into the lead.

Piquet closed the gap from fifteen seconds to four but Prost won the race and the World Championship after a breathtakingly exciting race. Third place in the race went to Stefan Johansson in his last race for Ferrari with Martin Brundle fourth in his Tyrrell. Streiff was fifth and Johnny Dumfries (Lotus) sixth.

In Sky TV's "Tales from the crypt" Mansell said that at the end of year FIA Paris prizegiving, Bertie Martin, the Clerk of the Course at Adelaide, told him that had he hit the wall and debris covered the track, he would have red-flagged the race and, as two thirds race distance had been completed, Mansell would have been world champion.

from Grokipedia
The 1986 Formula One World Championship was the 37th season of FIA-sanctioned motor racing, contested over sixteen Grands Prix from 23 March in to 26 October in . of McLaren-TAG secured his second consecutive drivers' title with 72 points and 4 wins, prevailing by a mere two points over (70 points, 5 wins) and three over (69 points, 4 wins), both of Williams-Honda, in a season defined by tactical precision amid mechanical unreliability. Williams-Honda dominated the constructors' standings with 141 points, powered by their turbocharged V6 engines that propelled the team to nine race victories despite internal driver tensions. The season epitomized the turbocharged era's peak, with atmospheric engines phased out and boost pressures capped at 4.0 bar, yet failures like Mansell's catastrophic tire blowout while leading the decisive underscored the technology's fragility, handing Prost the championship without completing the race distance himself. McLaren's early dominance, fueled by Prost's consistency and Keke Rosberg's experience, gave way to Williams' mid-season resurgence, highlighted by Piquet's strategic wins and Mansell's aggressive pursuits, fostering a three-way title fight that captivated fans. Lotus-Renault's emerged as a prodigy with two victories, including a masterful Monaco defense, signaling the arrival of turbo power's next generation, while Ferrari's and managed only sporadic podiums amid reliability woes. Controversies abounded, including Williams' intra-team dynamics where Piquet's experience clashed with Mansell's raw speed, leading to accusations of favoritism, and broader debates over turbo regulations as ground-effect aerodynamics began influencing designs toward the 1987 ban on turbochargers. Prost's championship, earned through four wins—matching Piquet's tally but one fewer than Mansell's five—via superior points maximization amid rivals' retirements, exemplified endurance over outright pace in an era where and tire management proved decisive causal factors in outcomes.

Participants

Constructors and Engine Suppliers

The 1986 Formula One World Championship featured 14 constructors, all employing turbocharged 1.5-liter engines in line with FIA regulations that permitted unrestricted boost until the season's end, marking the zenith of turbocharged dominance before fuel and boost restrictions in subsequent years. Engine suppliers ranged from established manufacturers like , , and Ferrari to independent tuners adapting BMW inline-four units, with power outputs often exceeding 800 horsepower in qualifying trim due to minimal restrictions. Key pairings included factory-supported efforts such as Williams with Honda's RA166E V6, which delivered superior reliability and power for nine victories, and with the TAG-badged Porsche TPE V6, securing four wins despite less outright power than rivals. Lotus and relied on Renault's EF15 V6 turbo for competitive straight-line speed, while Ferrari fielded its in-house Tipo 037 V6. Lower-order teams adopted varied solutions: Benetton and used tuned BMW M12/13 inline-four turbos renowned for qualifying prowess, Arrows similarly with BMW power, Tyrrell with Renault EF4B V6, and with Ford Cosworth GBA V6. Independent engines appeared in Zakspeed's proprietary 1500/4 inline-four, Motori Moderni V6 for Minardi and AGS, 890T V8 for , and Hart 415T inline-four for select entries.

Driver Line-ups and Nationalities

The primary driver line-ups for the 1986 Formula One World Championship featured established pairings across 13 constructors, with drivers representing nationalities including British, Brazilian, French, Finnish, Italian, Swedish, Austrian, German, Swiss, Dutch, Canadian, and Australian. These line-ups were finalized prior to the season opener in on March 23, with most teams retaining experienced pilots amid the turbo era's competitive landscape.

These modifications balanced competitive density with practical constraints, ensuring the season commenced on March 23 in and concluded on October 26 in .

Regulations and Rulemaking

Background to Regulatory Shifts

The turbocharged engine formula, permitted under FIA regulations since alongside 3-liter naturally aspirated options, gained prominence after debuted the technology in 1977, securing the first turbo victory at the . By the early 1980s, following the 1983 prohibition of adjustable skirts that had enabled extreme ground-effect , teams increasingly prioritized raw engine power to compensate for reduced and grip, propelling turbo units to dominance across the grid. This shift amplified straight-line speeds, with qualifying configurations routinely exceeding 1,200 horsepower and top speeds surpassing 350 km/h, exacerbating turbo lag—delays in power delivery that complicated control during braking and corner entry. Safety apprehensions mounted as accident data revealed the perils of such outputs; for instance, turbo-equipped cars demonstrated poor deceleration under panic braking due to boost dependency, contributing to incidents like high-speed impacts in testing and races. The FIA, led by president , viewed unrestricted turbo development as unsustainable, citing not only hazards but also escalating costs for manufacturers investing in bespoke 1.5-liter units capable of qualifying boosts without limits. Rather than immediate bans, which risked legal challenges from engine suppliers, the governing body opted for indirect curbs via fuel consumption formulas introduced in , mandating efficiency to temper power without altering core technical specs. These measures culminated in the 1986 regulations, which reduced the race fuel allowance to 195 liters from 220 liters the prior year, compelling teams to detune engines or optimize mapping for endurance over peak output. Qualifying remained unconstrained by boost pressure, allowing transient spikes to historic highs, but the FIA signaled future intent by announcing in late 1985 a transition to naturally aspirated engines from 1989, with interim steps like re-permitting 3.5-liter atmospheric units in 1987 alongside capped turbo boost via pop-off valves. This phased strategy reflected causal priorities: prioritizing empirical data from crash analyses over manufacturer preferences, while acknowledging turbos' allure amid debates on spectacle and for smaller teams.

Technical Regulation Updates

The 1986 Formula One season mandated the exclusive use of 1.5-litre turbocharged engines, explicitly prohibiting naturally aspirated units that had previously been permitted alongside turbos. This regulation aligned with the ongoing turbo era, where remained capped at 1.5 litres but cylinder count, RPM limits, and power output faced no restrictions, enabling outputs exceeding 1,000 horsepower in qualifying trim. Fuel capacity was reduced to a maximum of 195 litres per race, down from 220 litres in the prior season, compelling teams to prioritize efficiency and strategic management over unrestricted consumption. This change aimed to mitigate the extreme power-to-weight advantages of turbos by limiting refueling stops and overall energy availability, though boost pressure enforcement via pop-off valves was deferred until 1987. Chassis weight minimums were set at 500 kg, a slight reduction from previous years, while dimensions such as (maximum 1,800 mm) and track width (maximum 1,400 mm front/rear) remained largely unchanged from specifications. Aerodynamic aids like movable skirts and fans for ground effect were already banned since 1983, with no further alterations to bodywork or suspension geometry introduced for 1986. These updates collectively sustained turbo dominance while incrementally curbing excesses through fuel constraints, setting the stage for subsequent restrictions that phased out unrestricted turbos after 1988.

Sporting and Event Procedure Changes

In 1986, the FIA enhanced event protocols by mandating a permanent medical service inspector to supervise all World Championship events, ensuring consistent oversight of medical facilities and response readiness across circuits. A medical was also made obligatory at every Grand Prix, enabling swift aerial transport for seriously injured drivers or personnel in remote or high-risk track sections. These procedural updates, implemented in response to escalating accident risks from turbocharged cars exceeding 1,000 horsepower in qualifying, prioritized causal factors like rapid extrication and trauma care over prior ad-hoc arrangements by national authorities. No alterations were made to core qualifying formats, which retained the established two one-hour sessions on and , with grid positions determined by best individual times rather than aggregates. Race starting procedures remained standing starts from a five-minute preparation window, with no modifications to penalty enforcement or flag signaling under the . Fuel allocation during events continued under technical limits of 220 liters per race, but sporting rules prohibited refueling, maintaining emphasis on pre-race strategy without mid-event stops for additives.

Technical Developments

Turbocharged Engine Dominance and Specifications

The 1986 Formula One season represented the zenith of turbocharged engine supremacy, as regulations mandated exclusively 1.5-liter turbocharged power units, eliminating the option for naturally aspirated 3.0-liter engines that had persisted until that year. This shift compelled all entrants to adopt turbo technology, yielding power outputs that eclipsed prior eras and propelled cars to record speeds, though at the cost of drivability issues like turbo lag and high fuel consumption. Turbo engines dominated due to their capacity to generate over 1,000 brake horsepower in qualifying configurations from compact displacements, far surpassing the 500-600 bhp of contemporary road cars and enabling straight-line acceleration that defined the era's spectacle. FIA technical regulations stipulated a maximum engine displacement of 1.5 liters for turbocharged units, with no imposed limit on boost pressure, allowing manufacturers to push boundaries via advanced turbo sizing, intercooling, and fuel mapping. To curb excessive power without direct boost caps—deferred to 1987—a fuel capacity restriction of 195 liters per race was enforced, compelling teams to balance boost levels against endurance and strategy. Configurations predominantly featured V6 layouts for compactness and vibration control, supplemented by inline-four designs like BMW's, all paired with single or twin turbochargers exhausting high-pressure exhaust gases to spin impellers delivering forced induction. Prominent engines included Honda's RA166E, a twin-turbocharged 80-degree V6 supplying Williams with estimated 1,200 in qualifying and over 1,000 in race trim, emphasizing reliability over peak output. BMW's M12/13 inline-four, derived from a road car block, achieved dyno-limited peaks of 1,400 in qualifying for teams like Benetton and , though race versions hovered around 900 to preserve components. Porsche's TAG-Porsche V6 powered to around 850-950 in competition, while Ferrari's Tipo 032 V6 and Renault's EF-type V6 offered competitive outputs in the 1,000 qualifying range, underscoring the in turbo efficiency and heat management.

These specifications highlighted turbo dominance through sheer force, yet foreshadowed regulatory backlash as power levels strained chassis, tires, and safety margins, culminating in the era's phase-out by 1989.

Atmospheric Engine Challenges and Innovations

In 1986, the FIA's technical regulations explicitly prohibited naturally aspirated (atmospheric) engines, mandating 1.5-liter turbocharged units as the sole permissible powerplant configuration, marking the only season in Formula One history with such a restriction. This rule change, implemented to homogenize competition and accelerate turbo technology adoption, stemmed from atmospheric engines' prior competitive disadvantages: under 1984–1985 rules allowing 3.0-liter atmospheric designs alongside turbos, the latter delivered peak outputs exceeding 1,000 horsepower on unrestricted fuel, while top atmospheric units like updated Cosworth DFVs hovered around 500 horsepower, rendering them unviable for front-running teams. The ban thus presented a regulatory challenge, halting atmospheric development mid-cycle and forcing resource allocation to turbo suppliers amid escalating costs—estimated at over $1 million per season per team for turbo programs—and reliability issues, as turbo failures contributed to 20% of retirements in qualifying and races. Despite the prohibition, turbo dominance exposed inherent limitations that indirectly underscored atmospheric engines' potential advantages, such as superior response and drivability absent turbo lag, which could delay power delivery by 0.5–1 second at low RPMs. Mid-season turbo woes, including the 220-liter race fuel limit curbing unrestricted boost to manage consumption rates above 100 liters per 100 km, prompted FIA reconsideration; by September , officials signaled a shift, announcing 3.5-liter atmospheric engines' return for to foster parity and curb turbo excesses. This transition catalyzed innovations in atmospheric design during late-1986 preparations: displacement increased to 3.5 liters to target 650–700 horsepower via higher , with engineers prioritizing lightweight components and refined port geometries for rev limits up to 13,000 RPM, contrasting turbo engines' sub-10,000 RPM ceilings under boost constraints. Key advancements included Cosworth's DFZ V8, evolved from the DFV with narrower bore spacing for better and pneumatic valve returns to sustain high RPM without springs, debuting in 1987 testing at on October 15, 1986, yielding initial dyno figures of 585 horsepower at 12,500 RPM. Similarly, Motori Moderni began Tipo 930 V6 development, emphasizing compact packaging and electronic fuel mapping for efficiency gains over prior 3.0-liter limits. These efforts addressed core atmospheric challenges—power deficits—through first-principles optimization, though real-world deployment in 1987 revealed persistent gaps, with atmospheric units averaging 100–150 horsepower less than restricted turbos despite no fuel caps, highlighting the era's causal trade-offs between reliability and raw output.

Chassis, Aerodynamics, and Tire Evolutions

The chassis designs in the 1986 season emphasized lightweight carbon fiber monocoques to handle the high power outputs of turbocharged engines while complying with post-1983 flat-floor regulations that prohibited ground-effect aerodynamics. Teams like Williams constructed their FW11 with a full carbon monocoque in an inverted 'U' configuration, prioritizing structural integrity and driver packaging around the compact turbo units. This approach allowed for better weight distribution and rigidity compared to earlier aluminum-honeycomb hybrids, contributing to improved handling under the 2.5-bar boost limit enforced from the Spanish Grand Prix onward. Suspension systems evolved toward greater sophistication, with pushrod setups at the front and pullrod at the rear becoming standard for optimizing geometry and reducing unsprung mass. Lotus's 98T featured early hydro-pneumatic elements influencing control, precursors to full systems that would emerge prominently in subsequent years, though 1986 implementations remained largely mechanical to adjust to varying track conditions and turbo lag. These refinements enabled cars to maintain stability at speeds exceeding 300 km/h, despite the era's powerful but peaky engines. Aerodynamic developments focused on drag reduction and efficient airflow management around turbo intercoolers and radiators, with sidepods redesigned to curve inward as engines were positioned further forward for better cooling. The exemplified clean, low-drag profiles that balanced generation via wings and diffusers with minimal turbulence, reflecting a shift from radical ground-effect pursuits to subtler optimizations under restrictive rules. Such evolutions prioritized straight-line speed on power circuits while preserving cornering grip, as teams grappled with the turbo era's emphasis on engine performance over aero complexity. Tire technology saw intense competition between Goodyear, which supplied the majority of teams, and , limited to outfits like Benetton, driving annual compound advancements for enhanced grip on high-torque turbo cars. Innovations included tailored tread patterns and rubber formulations to manage the increased thermal loads and cornering forces from boost-limited engines delivering over 800 horsepower in qualifying trim. This rivalry spurred rapid iteration, with Goodyear's dominance evidenced by their support for 15 of 16 entrants, ensuring tires could withstand the season's demanding schedules without sole-supplier complacency.

Pre-Season Context

Testing Regimes and Early Incidents

In preparation for the 1986 season, teams conducted unrestricted private testing at circuits including in and the Jacarepaguá circuit in Rio de Janeiro, focusing on reliability, fuel efficiency under the new 195-litre race limit, and chassis setups for the mandatory 1.5-litre turbo engines. The Fédération Internationale du Sport Automobile (FISA) imposed no caps on testing days or collective sessions, enabling intensive development but exacerbating costs amid the in boost pressure and . Teams like Williams- utilized these sessions to validate the FW11's precursor and RA166E engine integration, with early laps indicating superior straight-line speed compared to rivals such as McLaren-TAG. A notable early incident unfolded on 8 March 1986, during Williams' pre-season test at . Team principal Frank Williams, en route to Marseille airport in a rental , engaged in an impromptu race with driver in a separate , leading to a high-speed crash that severed Williams' at the neck and caused permanent quadriplegia. Piquet escaped unharmed, but the accident, occurring just 15 days before the Brazilian Grand Prix opener, forced deputy to assume leadership, compounding challenges from the team's transition to power. No major on-track testing crashes were reported pre-season, though the era's high power outputs—exceeding 1,000 horsepower in qualifying trim—underscored inherent risks in unmonitored sessions lacking modern safety protocols like mandatory medical response vehicles.

Team Preparations and Expert Predictions

Teams entering the 1986 season prepared amid anticipation of it being the final year for turbocharged engines before the 1987 ban on turbochargers, with preparations emphasizing power output balanced against the 195-liter fuel limit per race. Williams-Honda focused on the newly developed FW11 , designed by Frank Dernie and , which featured refined and integrated seamlessly with Honda's RA166E 1.5-liter V6 , capable of over 1,000 horsepower in qualifying trim.

Incidents and Safety Issues

Elio de Angelis Testing Fatality

, the Italian driver who had joined the team after departing Lotus at the end of 1985, was conducting a private testing session for the new BT55-BMW at the circuit in on May 14, 1986. The BT55 featured an unconventional low-line aerodynamic design aimed at improving straight-line speed under the era's ground-effect regulations, but it proved unreliable during early development. Around 11:00 a.m., while navigating the high-speed S-bend (Verrerie section) after the pit straight at approximately 290 km/h, the rear wing of de Angelis's BT55 detached, causing a sudden loss of downforce. The car pitched violently, became airborne, cleared the guardrail, and landed inverted beyond the barriers, with the survival cell remaining structurally intact but the roll hoop severely damaged, leading to a fuel leak that ignited a fierce fire. Initial response was hampered by the private nature of the test, with only two unprepared marshals nearby; fellow drivers Alan Jones and arrived first but lacked adequate equipment to extinguish the blaze. A fire truck arrived belatedly, but its hose malfunctioned, forcing responders to wait for the flames to subside before righting the car and extracting de Angelis, who had suffered burns over 30% of his body and . He was airlifted by to a hospital in approximately 30 minutes after the crash, but succumbed to cerebral from oxygen deprivation on May 15, 1986. The incident, the first Formula One driver fatality in four years, exposed critical gaps in testing protocols, including insufficient on-site medical and fire suppression resources at non-race events. Brabham's technical director, Gordon Murray, later confirmed the wing failure stemmed from inadequate structural testing of the prototype component under load. De Angelis's death left Brabham scrambling for a replacement, ultimately signing Derek Warwick mid-season, while underscoring the risks of rapid car development without robust safety redundancies.

On-Track Crashes and Mechanical Failures

During the at on July 13, a significant multi-car collision unfolded at the start when lost control of his Arrows-BMW, triggering a that sent Jacques Laffite's Ligier-Renault into a head-on impact with a barrier. Laffite, attempting to match Graham Hill's record of 176 Grand Prix starts, sustained bilateral leg fractures requiring extraction from the wreckage and to , ultimately forcing his retirement from at age 42. The incident highlighted vulnerabilities in starting procedures and barriers at high-speed corners, though no fatalities occurred. The season finale at the Australian Grand Prix in on November 16 featured dramatic mechanical failures, including a left-rear tyre delamination on Nigel Mansell's Williams-Honda while he pursued the lead at over 200 km/h. Mansell maintained control to avoid a barrier strike but retired, forfeiting a potential championship-clinching victory and handing the drivers' title to by three points. Earlier in the same race, Keke Rosberg's Williams-Honda suffered a similar tyre failure, prompting precautionary changes for teammate and underscoring Goodyear tyre durability issues under turbocharged loads. Additional mechanical setbacks plagued frontrunners, such as Mansell's consecutive retirements due to component failures in the British and German Grands Prix, eroding his points lead amid the intense . These events, compounded by turbo engine unreliability across teams like Williams and , amplified the season's unpredictability, where high-boost and power units often exceeded component tolerances at speeds exceeding 300 km/h. No driver fatalities resulted from race-day incidents, distinguishing on-track risks from the era's testing hazards.

Broader Safety Implications During the Season

The death of on May 15, 1986, during a private test at the circuit exposed systemic vulnerabilities in Formula One's safety framework, particularly for non-competitive sessions lacking the robust medical infrastructure of race weekends. De Angelis' suffered rear wing failure at high speed, leading to a barrier impact, chassis disintegration, and an intense fire; he remained trapped for approximately 28 minutes due to delayed extraction amid inadequate firefighting equipment and procedures, ultimately succumbing to and burns rather than direct crash trauma. This incident revealed causal gaps in trackside response times, fire suppression efficacy, and barrier energy absorption, as testing venues prioritized speed over emergency preparedness, amplifying risks from the era's fragile, high-downforce designs. In direct response, the FIA instituted immediate procedural enhancements for the remainder of the 1986 season, including the appointment of a permanent medical service inspector and the mandatory deployment of medical helicopters at all events to facilitate rapid . These reforms addressed the de Angelis crash's key failure points—slow intervention and limited aerial medical access—by standardizing protocols across testing and , though they did not retroactively equip private sessions with race-level oversight. No in-race driver fatalities occurred that year, yet the testing maintained pressure on organizers to mitigate turbo-era hazards, where unrestricted boost levels up to 5.5 bar generated over 1,100 horsepower, fostering unpredictable handling and amplifying crash severities from minor component failures. The season's broader safety discourse emphasized causal links between technological excesses and human vulnerability: turbocharged cars achieved straight-line speeds exceeding 340 km/h but suffered from twitchy throttles and brittle , contributing to incidents like suspension fractures and tyre degradations under , as evidenced by multiple retirements from mechanical overloads at circuits such as and . Drivers and teams, including voices from and Williams, advocated for preemptive limits on power outputs and aerodynamic loads to avert survivable crashes escalating into catastrophes, foreshadowing the 1987 turbo pressure caps at 4.0 bar and pop-off valve mandates. However, mid-season adaptations remained incremental, prioritizing operational continuity over radical redesigns, as empirical data from the 16 Grands Prix showed zero race-day deaths but underscored testing's unregulated dangers as a persistent blind spot.

Championship Dynamics

Drivers' Title Rivalry: Prost, Mansell, and

of McLaren-TAG entered the 1986 season as the defending drivers' champion, leveraging the reliability of his TAG- turbocharged engine to score points in 13 of the 16 races, securing four victories at , , , and . His consistent finishes, often capitalizing on rivals' misfortunes, positioned him to clinch the title despite the McLaren's inferior straight-line speed compared to the Honda-powered Williams cars. Prost amassed 72 points from his best 11 results, demonstrating a calculated approach that prioritized finishing over aggressive risks. Nigel Mansell, piloting the dominant Williams-Honda FW11 for the British team, led the championship for much of the season with five wins, including at , , Brands Hatch again? Wait, specific: but his aggressive driving style yielded high rewards but also vulnerabilities, such as a dramatic tire delamination while leading the on September 21, which handed victory to Prost and shifted the points lead. Mansell's intra-team tension with teammate escalated, as the Brazilian's experience clashed with Mansell's hunger, leading to instances where Williams' no-orders policy resulted in both drivers losing potential points to each other, exemplified by their duels in races like Britain and . This rivalry diluted Williams' dominance, with Mansell ending on 70 points, just two behind Prost. Nelson Piquet, the two-time champion joining Williams from , brought tactical acumen but struggled with the FW11's handling early on, managing only one win at ? Wait, German GP, and relying on strategic decisions like undercutting rivals. His 69 points placed him third, undermined by a spin in the season finale at on , where he lost positions after Mansell's earlier error, allowing Prost's opportunistic pit strategy to secure the win and title. Piquet's deference to team priorities sometimes conflicted with Mansell's assertiveness, fracturing Williams' strategy and enabling Prost's opportunistic consistency to prevail in the closest drivers' championship finish to that point.

Constructors' Competition and Team Strategies

The 1986 Constructors' Championship was dominated by , which secured the title with 141 points from nine race victories, clinching the championship at the on September 21 after Nigel Mansell's win extended their lead beyond reach. McLaren-TAG finished second with 96 points, relying primarily on Alain Prost's consistent performances, while Lotus-Renault placed third with 58 points, bolstered by Ayrton Senna's six podiums. Ferrari lagged in fourth with 37 points, hampered by less competitive turbo machinery compared to the and units. The competition highlighted the advantages of turbocharged engines under fuel-limited conditions, where boost management and efficiency were critical.

Williams' strategy centered on the FW11 chassis paired with the potent RA166E V6 turbo engine, producing over 800 horsepower while emphasizing reliability and fuel efficiency to comply with the season's 220-liter fuel limit and pop-off valve restrictions. The team's decision to field two title-contending drivers, and Mansell, maximized scoring opportunities, with internal rivalry driving development and race pace, though it occasionally led to on-track clashes that risked points. This approach contrasted with McLaren's heavier dependence on Prost, as teammate , returning from retirement, managed only sporadic results before announcing his full-season withdrawal intent, limiting the team's dual-car potential. Lotus, meanwhile, prioritized innovations on the 98T but suffered from engine reliability issues, forcing conservative strategies that conserved Senna's points haul despite his qualifying prowess. Broader team tactics involved meticulous fuel conservation modes to stretch stints, as refueling was prohibited, turning races into endurance tests where engine mapping adjustments for partial efficiency proved decisive. Williams excelled here, leveraging 's to sustain competitive times without excessive boost, yielding higher finish rates than rivals plagued by mechanical failures or over-aggressive power settings. McLaren's TAG-Porsche power unit offered raw speed but demanded careful management to avoid breakdowns, a factor in their constructors' deficit despite Prost's drivers' title. These strategies underscored causal factors in success: superior integration and driver pairing outweighed isolated brilliance, enabling Williams to amass points across 23 entries while others faltered in consistency.

Key Controversies in Title Contention

The 1986 drivers' championship featured a heated intra-team rivalry at Williams between and , which intensified scrutiny over resource allocation and driver management. Piquet, entering the season as a two-time champion with a contractual number-one status, grew resentful as team principal Frank Williams treated both drivers equally, refusing to impose orders despite Piquet's superior experience. This dynamic led to public barbs, including Piquet's derogatory comments labeling Mansell as intellectually limited in a interview, escalating personal animosity that distracted from unified efforts against McLaren's . The lack of favoritism, while fostering competition, arguably diluted Williams' constructors' push and contributed to inconsistent results for the team. The rivalry's impact peaked in the season finale at the Australian Grand Prix on October 26, 1986, where Mansell held a seven-point lead over Prost and , both on 63 points; Mansell needed to outscore Prost by at least eight points to clinch the title outright. In dry conditions early on, the Williams duo dominated, with Mansell pulling a substantial lead of over 30 seconds after overtaking Prost, who had started from fourth on . However, on lap 64 of 82, Mansell's left-rear Goodyear tire suffered a dramatic blowout while he was pushing aggressively, retiring him from the race and extinguishing his championship hopes; Goodyear attributed the failure to debris from earlier incidents, such as René Arnoux's crash, rather than tire defect or overuse. Piquet inherited the lead but faced immediate controversy when Williams, heeding Goodyear's precautionary advice amid fears of similar failures, pitted him for fresh tires on lap 67, dropping him behind Prost, who opted to stay out on worn rubber in the increasingly treacherous conditions. Prost, conserving fuel and tires without mounting a full challenge, held off Piquet's late charge to win the race by 4.210 seconds, securing nine points to Prost's total of 72, while Piquet's six points left him on 69; Mansell remained on 70. Critics, including Piquet himself, argued the pit stop was overly cautious, as his tires might have endured to victory, potentially awarding him the title by a single point over Prost. Prost's title win, his second consecutive, drew debate over strategic conservatism versus outright speed, with detractors claiming he benefited from rivals' misfortunes rather than dominating the finale, though his season-long consistency—four wins to Mansell's five, but fewer retirements—underpinned the outcome under the era's nine-six-four-three-two-one scoring . No formal protests were lodged, but the events highlighted vulnerabilities in tire management and under pressure, influencing perceptions of the championship's legitimacy amid the turbo era's unreliability.

Scoring Methodology

Points were awarded to the top six classified finishers at each Grand Prix, with the winner receiving 9 points, second place 6 points, third place 4 points, fourth place 3 points, fifth place 2 points, and sixth place 1 point. Classified finishers were those who completed the required distance or were running at the time of a race suspension, adhering to FIA regulations that mandated at least 75% of the race distance for full points unless otherwise specified. No additional points were given for pole position, fastest lap, or other qualifying achievements. For the Drivers' World Championship, points were tallied from a driver's best 11 results across the season's 16 Grands Prix, allowing discard of the five lowest-scoring or non-finishing rounds to determine the final standings. This system incentivized consistent performance while mitigating the impact of mechanical failures or accidents, as evidenced by Alain Prost's championship-winning total of 72 points derived from 74 accumulated, after dropping two lesser results. In contrast, the Constructors' World Championship summed all points earned by a team's two nominated drivers across every race, without discarding any results, emphasizing team reliability and depth. Williams-Honda secured the title with 141 points from both and Nelson Piquet's contributions in all events. Half points were awarded in cases where a race was red-flagged and not resumable before reaching the two-thirds distance threshold, as occurred in the season-ending due to , where Prost scored 4.5 points for his second-place finish.

Legacy and Causal Analysis

Regulatory Aftermath and Turbo Era's End

Following the 1986 season, the FIA implemented restrictions on turbocharged engines for 1987 to address escalating power outputs, safety risks, and development costs that had rendered naturally aspirated engines obsolete and widened disparities between top teams and smaller outfits. Boost pressure was capped at 4.0 bar via mandatory pop-off valves that vented excess pressure, reducing qualifying outputs from over 1,200 horsepower in 1986 to approximately 800-900 horsepower, while race power fell to around 650-700 horsepower under fuel limits. These measures, combined with reintroducing 3.5-liter naturally aspirated engines (previously banned in favor of compulsory 1.5-liter turbos for 1986), aimed to level competition by favoring reliable, drivable power over peak bursts prone to turbo lag and sudden surges. The progressive curbs reflected mounting concerns over fatalities in turbo-equipped cars from 1982 to 1987, including crashes exacerbated by high-speed instability and limited driver control under unrestricted , prompting the FIA to prioritize alongside cost control as turbo development costs exceeded $10-15 million per team annually by 1986. Minimum car weight dropped to 500 kg from 575 kg to offset power reductions and encourage closer racing, but turbos remained eligible through with further fuel caps (195 liters per race in , tightening to 150 liters in ). By late 1986, amid rumors circulating since mid-season, the FIA confirmed turbochargers would be outright banned from 1989, enforcing a uniform 3.5-liter naturally aspirated formula that dropped peak power to 600-700 horsepower and shifted emphasis to and aerodynamics. This transition marginalized turbo specialists like and , who withdrew, while prompting suppliers such as and Ferrari to pivot to aspirated designs, ultimately fostering a more accessible era with broader manufacturer participation but ending the raw power dominance that defined 1984-1986.

Influence on Driver Strategies and Risk Assessment

The 1986 Formula One season, operating at the zenith of the turbocharged era, imposed stringent demands on driver risk assessment owing to engines delivering over 1,000 horsepower in race trim and up to 1,200 in qualifying, coupled with handling traits prone to sudden oversteer from turbo lag. These factors amplified the perils of aggressive cornering or suboptimal boost application, where miscalculations could precipitate spins, barrier impacts, or accelerated component wear, as evidenced by frequent retirements from mechanical stress across the grid—Williams-Honda entries suffered only 4 DNFs from accidents but multiple from failures when pushed. Drivers thus calibrated strategies around probabilistic failure rates, weighing instantaneous lap time gains against cumulative reliability costs, a paradigm shift from aspirated eras where raw speed margins were more forgiving. Alain Prost's championship-winning approach epitomized this evolution, leveraging McLaren's TAG-Porsche turbo's relative durability to pursue metronomic consistency: four victories from consistent top finishes, retiring just twice from mechanical issues despite the car's qualifying pace deficit to rivals. and , in the superior Williams-Honda, adopted riskier profiles—Mansell with five wins but six retirements, Piquet more measured yet still aggressive—highlighting intra-team tensions where Piquet's fuel-conserving tactics in races like preserved machinery at the expense of outright pace. Prost's "Professor" moniker derived from this data-informed restraint, analyzing tire degradation and fuel mapping mid-race to optimize points expectancy, contrasting Mansell's visceral pushes that yielded highs but invited volatility. The Australian Grand Prix on November 2, 1986, crystallized these strategic divergences: Mansell, holding a two-point lead, accelerated aggressively on degrading Goodyear tires to extend his advantage, suffering a left-rear blowout at 200 mph on lap 18 while leading by 1 minute 8 seconds, stranding him with irreparable damage and extinguishing his title bid. Prost, in third initially, methodically advanced via rivals' pit stops and conservative pacing—managing a faltering and tires to claim second behind race-winner —netting four points to finish with 72 against Mansell's 70 and Piquet's 69, the closest drivers' championship in . This incident underscored causal links between overcommitment and failure in high-pressure contexts, where Mansell's strategy ignored empirical warnings from prior tire wear data, while Prost's adhered to risk-minimizing protocols. Post-season analyses affirmed the season's didactic impact on driver cognition, embedding as a : teams like integrated telemetry-driven simulations for , influencing future protocols where drivers quantified "mechanical sympathy" via lap-time variance thresholds to avert Prost-Mansell dichotomies. The turbo era's volatility thus catalyzed a transition toward analytical , prioritizing over heroism, a framework persisting beyond the turbo ban as drivers confronted evolving uncertainties in naturally aspirated and hybrid regimes.

Empirical Evaluation of Season's Competitive Intensity

The 1986 drivers' championship demonstrated exceptional competitive intensity, culminating in Alain Prost's victory with 72 points, a mere 2-point margin over (70 points) and 3 points over (69 points). This razor-thin separation among the top three drivers, all contending until the final race, highlighted sustained rivalry rather than early dominance. Entering the Australian Grand Prix, Mansell held a 2-point lead over Prost and a 6-point advantage over Piquet, but a tire failure while leading forced his retirement, allowing Prost's third-place finish to secure the title by 4 points. Race outcomes further underscored the season's parity at the elite level, with 5 different winners across 16 grands prix: Mansell (5 victories), Prost (4), (3), (2), and (1). Despite Williams-Honda and McLaren-TAG engines powering 15 of 16 wins, the distribution reflected driver skill and reliability challenges amid turbocharged power outputs exceeding 1,100 horsepower in qualifying. Pole positions were more fragmented, with Senna claiming 8 despite his Lotus-Renault's relative underperformance in races, compared to Mansell's 5, illustrating qualifying battles independent of outright race pace. The lead changed 10 times, a high frequency indicating volatility driven by mechanical failures, strategic decisions, and intra-team dynamics, particularly at Williams where Mansell and split points. Constructors' standings mirrored this tightness, with Williams-Honda edging McLaren-TAG by 2 points (141 to 139), as both teams maximized scoring across multiple events without the drivers' discard rule applying to team totals. This outcome stemmed from consistent top finishes rather than lopsided supremacy, contrasting seasons with larger gaps.
