The McLaren M18 is an open-wheel Formula 5000 racing car designed and made by McLaren in 1971.
The car was conceived to participate in the 1971 Formula 5000 season to replace the M10.
The car was powered by a 470-hp Chevrolet V8, which drove the rear wheels through a five-speed manual gearbox.
The car, entrusted to the driver Brian Redman, did not have the hoped-for success and won only two of the 16 championship races.
