The McLaren MP4/4, also known as the McLaren-Honda MP4/4, is one of the most successful Formula One car designs of all time. Powered by Honda's RA168E 1.5-litre V6-turbo engine and driven by teammates Alain Prost and Ayrton Senna, the car competed during the 1988 Formula One season. It was designed by American engineer Steve Nichols, the full responsibility for the design of the chassis having been conferred on him by Ron Dennis. Gordon Murray, as Technical Director, subsequently confirmed this in an internal memo allocating responsibilities for the design department, nominating Nichols as chief designer for the car, and giving himself the role of liaising between the drawing office and production.
