The 1991 season dominator, MP4/6, designed by Neil Oatley, was the first McLaren powered by Honda V12 engine which was capable of 725 bhp. Other new feature of the car was a manual “H” pattern gearbox. A semi-automated transmission was tested during the season, but was considered as not good enough to be used in the race. In 1991 season the MP4/6 in hands of Ayrton Senna won 7 Grand Prix on the road to his third World Drivers’ Championship title. In the modified ‘B’ specification the MP4/6 was used in the first two Grand Prix of 1992 – in South Africa and Mexico. Senna finished 3rd at Kyalami and retired at Mexico City. The car was then replaced with the 1992 car, the MP4/7A.
