The 760 bhp (567 kW 771 PS) A6 V10 was then introduced, and while it gave Häkkinen third place at San Marino and Brundle second at Monaco, the engine was generally regarded as a 'hand grenade' due to frequent failures in testing, qualifying and races. The engine proved unreliable and both Häkkinen and Brundle retired from the first two races with each suffering one engine failure. The MP4/9 was initially powered by the Peugeot A4 V10 engine which produced around 700 bhp (522 kW 710 PS). Visually the car was otherwise very similar to the preceding MP4/8. The MP4/9 was the first and only McLaren F1 car to utilise Peugeot engines.ĭue to changes in Formula One regulations intended to return emphasis on driver skills, many technologies designed to aid the driver, such as active suspension, power-assisted brakes, ABS and traction control, which had featured on the previous season's car, were no longer permitted. For the 21st consecutive year, Marlboro was the team's title sponsor, with additional sponsorship from Hugo Boss, Shell and Goodyear. Frenchman Philippe Alliot deputised in the number 7 car at the Hungarian Grand Prix when Häkkinen was banned from driving in this race. The number 7 car was driven by Finn Mika Häkkinen, in his first full season with the team, while the number 8 car was driven by Briton Martin Brundle, who had signed from Ligier. The McLaren MP4/9 was a Formula One car designed by Neil Oatley and used by the McLaren team in the 1994 Formula One World Championship.
