The McLaren MP4/6 is a Formula One racing car designed by Neil Oatley for use by the McLaren team in the 1991 Formula One season. It was driven by reigning World Champion, Brazilian Ayrton Senna, and Austria's Gerhard Berger.

Pre-season[edit]

The MP4/6 was the first McLaren to be powered by a Honda V12 engine, which was rated at 710 bhp (529 kW; 720 PS). The car was tested by Berger in the off-season, but he was unimpressed with the new engine, feeling it was underpowered compared to the 690 bhp (515 kW; 700 PS) V10 engine used in the 1990 car, the MP4/5B. When Senna returned for pre-season testing he and Berger, along with Honda, knuckled down to try to solve the engine's problems. McLaren's domination in the early part of the year was mainly due to the lack of reliability of the 700 bhp (522 kW; 710 PS) Renault V10-powered Williams FW14.

The MP4/6 raced throughout 1991 with a manual "H" pattern gearbox. A semi-automatic transmission was tested during the season but was never regarded as good enough to be used in a race; Ferrari and Williams were the only teams to use semi-automatic gearboxes during 1991. The MP4/6 would go down as the last Formula One car to win a World Championship using a manual transmission or a V12 engine.

Season summary[edit]

Senna won the first four races of the season, in the United States, Brazil, San Marino and Monaco, before Williams and Nigel Mansell found their feet with the FW14, which dominated in mid-season. Consistent podium finishes throughout the year helped McLaren, but Senna insisted that Honda step up their engine development program and demanded further improvements to the car before it was too late. Honda responded with an updated version of the V12 engine, while Oatley redesigned various features of the car, particularly the sidepods and wings. Senna won in Hungary and Belgium before clinching his third and final Drivers' Championship in Japan with second place behind Berger; he then won the final race in Australia to secure the team's fourth consecutive Constructors' Championship.

McLaren continued with the MP4/6, upgraded to 'B' specification, for the first two races of 1992, Senna finishing third in South Africa. The car was then replaced with the official 1992 car, the MP4/7A.

The MP4/6 was considered by some to be the most competitive car in the Formula One field until Williams sorted the FW14, which was aerodynamically and technically more advanced. In all, the MP4/6 took eight Grand Prix wins and ten pole positions, and scored 148 points. The car brought a close to McLaren's domination of the sport, stretching back to the mid-1980s.

Other[edit]

In July 2017, Codemasters confirmed that the car will be appearing as one of the classic cars in the game F1 2017.
