The McLaren MP4/5, and its derived sister model, the McLaren MP4/5B, were highly successful Formula One racing cars designed by the McLaren Formula One team based in Woking, England, and powered by Honda's naturally-aspirated RA109E and RA100E V10 engines respectively. The chassis design was led by Neil Oatley, teaming up with Steve Nichols, Pete Weismann, Tim Wright, Bob Bell and Mike Gascoyne. As with the previous designs, Gordon Murray, as Technical Director, had the role of liaising between the drawing office and production. Osamu Goto was the Honda F1 team chief designer for the car's engine.[3][4]
The MP4/5 was loosely based on its 1988 predecessor, the all-conquering MP4/4. McLaren used the new car for half of the 1989 season using the Weismann Longitudinal Transmission from the MP4/4, and the MP4/5B with the Weismann Transverse Transmission for the last half of the 1989 season and for 1990, earning back-to-back drivers' and constructors' world titles with the type.
Over the course of two seasons, the MP4/5 took 16 wins, 36 podiums, 27 pole positions, and 263 points before it was replaced by the MP4/6 for 1991.
