The McLaren MP4/3 was the car with which the McLaren team competed in the 1987 Formula One World Championship. The car was designed under the leadership of long-time McLaren engineer Steve Nichols, in collaboration with Neil Oatley, Gordon Kimball, Tim Wright and Bob Bell. It was also the last McLaren car to be powered by the TAG-Porsche turbo engine that had been introduced in 1983. The car was driven by double World Champion Alain Prost, in his fourth season with the team, and Stefan Johansson, who moved from Ferrari.
