Originally a development of the 1971 McLaren M16 Indy car, the McLaren M23 was an extremely successful car that served the team from 1973 to 1977 making use of a Ford-Cosworth DFV V8 naturally aspirated engine. It took 14 poles, 16 wins, two drivers titles and a constructors championship. In its final year of competition it was most certainly more competitive than the new McLaren M26, and the drivers had to be asked by management to move onto the newer car.
1976 McLaren M23-D released as historic content with F1 2019.
