2018 FIA GT World Cup

The 2018 FIA GT World Cup (formally the SJM Macau GT Cup – FIA GT World Cup) was a Grand Touring (GT) sports car race held on the Guia Circuit in the Chinese Special Administrative Region of Macau on 18 November. It was the event's fourth annual edition eleventh GT3 car race in Macau. Only platinum and gold drivers were allowed to compete, but silver drivers were eligible on a case by case basis at the FIA GT World Cup Committee's discretion. The Stéphane Ratel Organisation, in collaboration with the Fédération Internationale de l'Automobile (FIA), promoted the race. The event was made up of two races: a 12-lap qualifying race to set the 18-lap main race's starting grid.

Augusto Farfus of BMW Team Schnitzer won the main race from pole position in a BMW M6 GT3. After winning the Qualification Race the afternoon before, Farfus led every lap of the main race to achieve his fourth Macau victory and his first since the 2009 Guia Race of Macau. BMW became the third manufacturer to win the race. Mercedes-AMG Team GruppeM Racing's Maro Engel finished second, and his teammate Edoardo Mortara finished third.

The 2018 FIA GT World Cup was confirmed at the FIA World Motor Sport Council meeting on March 9. The event was held in the Chinese Special Administrative Region of Macau thanks to a contract extension with race organisers. It was the race's fourth staging and the eleventh GT3 event in Macau, taking place on the 6.120 km (3.803 mi) Guia Circuit in the streets of Macau on November 18, 2018, after three days of practice and qualifying. The Stéphane Ratel Organisation (SRO) collaborated with the Fédération Internationale de l'Automobile (FIA) to promote the race; the SRO was appointed by the promoter Associação Geral Automóvel de Macau-China to form a field of cars. The manufacturers' championship was presented to the maker of the winning participant's car, in accordance with the event regulations. The FIA nominated tyre manufacturer Pirelli as the race's control tyre supplier for the fourth successive year.

Drivers had to have competed in an FIA-regulated championship race based on GT3 regulations in the previous two seasons or have significant experience in Grand Touring (GT) cars to enter the race. Only those with a platinum or gold racing licences could automatically enter. Silver-ranked drivers were also permitted, but they had to be approved individually by the FIA GT World Cup Committee. Bronze-rated competitors were not permitted to compete. Entries were open from 6 July to 31 August. The FIA released the entry list on 18 October. The entry list included 15 drivers from 11 different countries, and they came from series such as the ADAC GT Masters and the Blancpain GT Series. Maro Engel, Laurens Vanthoor and Edoardo Mortara, as well as 2007 Macau Grand Prix winner Oliver Jarvis, were all former FIA GT World Cup winners.

The FIA imposed a balance of performance to ensure a high level of parity. The Audi R8 LMS had 10 kg (22 lb) of ballast added. Meanwhile, the weight of the BMW M6 GT3 was decreased by 10 kg (22 lb) but the turbocharger boost was reduced. The Mercedes-AMG GT3 gained handling with a 20 kg (44 lb) reduction in ballast but lost performance due to a 1 mm (0.039 in) reduction in air restrictor size. The Nissan GT-R Nismo GT3 debuted in Macau, weighing 1,305 kg (2,877 lb), while the Porsche 911 GT3 R received no performance changes.

There were two half-an-hour practice sessions preceding the 18 November race. Robin Frijns's No. 66 Team WRT Speedstar Audi R8 LMS lapped fastest in the first practice session on the afternoon of 15 November at 2 minutes, 18.588 seconds, ahead of Mortara, Christopher Haase, Augusto Farfus and Earl Bamber. Four manufacturers were represented in the first five. The session was stopped for separate accidents at the Melco hairpin. Dries Vanthoor, Frijns' teammate, hit the outside wall and lost control, coming to a stop sideways across the circuit. His car's front-left bodywork was damaged, and the spoiler was removed. While attempting to avoid Dries Vanthoor, Mathieu Jaminet was unsighted and crashed into a wall, sustaining minor damage to his car's left door. Farfus was forced to stop after that. Four manufacturers occupied the first five positions in the second practice session on the morning of November 16th, with Bamber setting the fastest lap in the No. 912 Manthey Racing Porsche 911 GT3 R at 2 minutes, 17.436 seconds with three minutes remaining after adjustments and tyre changes. Second through fifth were Engel, Frijns, Laurens Vanthoor, and Farfus. When Haase lost control of his vehicle and collided with the barrier at the R Bend turn, the session ended prematurely.

Friday afternoon's half-hour qualifying session determined the qualification race's starting order through each driver's fastest lap times. Conditions were cool for qualifying. Raffaele Marciello's No. 999 GruppeM Racing Mercedes-AMG GT3 took pole position in his second race in Macau, as the only driver to go under 2 minutes, 17 seconds on his final timed lap at 2 minutes, 16.8 seconds time on his final timed lap. It was his second pole position in Macau since the 2013 Macau Grand Prix. Marciello demoted Farfus from pole to second, despite the latter lapping faster with two minutes remaining. Following late-session improvements and a battle between both drivers, Engel took third and Mortara was fourth, giving Mercedes three positions in the top four. Manthey's Bamber and Laurens Vanthoor were fifth and sixth, with Audi drivers Frijns, Haase, and Dries Vanthoor seventh through ninth. Jaminet qualified tenth. Alexandre Imperatori took 11th, followed by Adderly Fong and Darryl O'Young from Hong Kong in 12th and 13th. Jarvis qualified 14th in his first Macau race since winning the 2007 Macau Grand Prix and Tsugio Matsuda in 15th completed the starting order. Frijns outbraked himself at Lisboa corner and crashed into the barrier during qualifying, necessitating the use of a localised yellow flag with less than three minutes remaining.

The FIA changed the performance balance again before the qualifying race, reducing the minimum ballast of the three KCMG-fielded Nissan GT-R Nismo GT3s by 20 kg (44 lb) for better handling. The vehicles' performance was also improved, with turbocharger boost increases across the board. O'Young started from the back of the field after changing engines after qualifying.
