1977 McLaren M23 F1

Chassis Number: M23-12

Debuting in 1973, the McLaren M23 was a Formula One car designed by Gordon Coppuck with input from John Barnard. In its 5 1/2 year life, a total of thirteen cars were built. The modifications for 1976 included a six-speed Hewland gearbox, refined aerodynamics and a weight savings program that saved at least 30 pounds. Later that year, McLaren also replaced their onboard battery with a compressed-air starter system saving more weight.

Entering its fifth season of Formula 1 racing, the M23 was clearly showing its age. Halfway through the season, it was replaced by the slimmer M26. With 16 grand prix victories, two drivers, and one constructor championship, the M23 remains one of the most successful Formula 1 racers of the 1970s.

This car was driven by Jochen Mass to the following results during the Formula One World Championship in 1977:

2nd - Swedish GP, Anderstorp (Jochen Mass)
4th - Spanish GP, Jarama (Jochen Mass)
4th - Monaco GP, Monte Carlo (Jochen Mass)
9th - French GP, Dijon (Jochen Mass)
