Detroit street circuit
The streets of Detroit, in the U.S. state of Michigan, hosted Formula One racing, and later Championship Auto Racing Teams (CART) racing, between the 1982 and 1991 seasons. The street circuit course was set up near the Renaissance Center and the Cobo Arena, also including a small part of the M-1 highway, also known as Woodward Avenue. It is a flat circuit, with elevation ranging from 577–604 ft (176–184 m) above sea level.
The circuit was reopened on June 2, 2023, for the IndyCar Detroit Grand Prix race weekend with a modified and shortened layout.
Created largely in an effort to improve the city's international image, the race meant that the United States would host three Grands Prix in the 1982 season (the other two US races, Long Beach and Las Vegas, had been added to the schedule for similar purposes), the only nation in F1 history to do so until the 2020 season, when Italy also hosted three Grands Prix: Monza, Mugello, and Imola. The inaugural Detroit Grand Prix saw McLaren's John Watson claim victory after starting in 17th place, then the lowest grid position for an eventual race winner on a street circuit. (Watson would break his own record at Long Beach the next year by winning from 22nd place.)
1982 in Detroit would also see the last time to date (as of 2025) that a reigning World Drivers' Champion would fail to qualify for a Formula One World Championship Grand Prix. On that occasion it was Nelson Piquet in the Brabham-BMW turbo who, after numerous problems during initial qualifying, was in 28th position (only 26 cars would start), never got the chance to improve in final qualifying due to the final hour being held in wet conditions where lap times were at least 12 seconds slower.
The Detroit street circuit's place in Formula One history was assured when Michele Alboreto won the 1983 race driving a Tyrrell 011. This was the last of 155 Grand Prix wins for the 3.0L Cosworth DFV V8 engine, dating back to its debut at the 1967 Dutch Grand Prix in the hands of dual World Champion Jim Clark. It was also the last of 23 Formula One race wins for Tyrrell, who had won their first Grand Prix at the 1971 Spanish Grand Prix with that year's World Champion Jackie Stewart driving the Tyrrell 003.
The race soon gained a reputation for being horrendously demanding and gruelling, with the very bumpy track often breaking up badly under the consistently hot weather. It was perhaps the single hardest race on both car and driver in Formula One during the 1980s, often producing races of attrition in which a large number of cars would retire due to mechanical breakdown or contact with the narrow concrete walls. Brakes and gearboxes in particular were tested to their breaking points—the drivers had to brake hard more than 20 times per lap and change gears around 50 to 60 times in one lap (cars still had manual gearboxes in those days), for 62 laps usually lasting around 1 minute and 45 seconds. At least half the field retired in each race; it was thus considered an achievement if a driver could even finish the race, let alone win it.
The 1984 race, won by reigning World Champion Piquet, tied an F1 road course record by featuring 20 retirements. Shortly after the race, impurities were found in the water injection system of Martin Brundle's Tyrrell, causing him to be stripped of his 2nd-place finish and Tyrrell (by then the only team still using the naturally-aspirated DFV) to be disqualified from the entire 1984 season. The race's five classified finishers (discounting Brundle) is beaten only by the 1966 Monaco Grand Prix.
By 1985, Detroit was the sole American venue on the F1 calendar—Las Vegas had been dropped after 1982, Long Beach switched to CART for 1984, and a new event in Dallas only lasted one year after the heat and deteriorating track conditions almost saw it cancelled on the morning of the race. That year saw Ayrton Senna take pole position, and he went on to enjoy substantial success at the circuit, winning the 1986, 1987, and 1988 races, as well as taking further pole positions in 1986 and 1988.
