The McLaren M23 first appeared in 1973, and became McLaren's first World Championship winner when Emerson Fittipaldi took the title in 1974. As depicted in the new feature film Rush, James Hunt gloriously repeated the feat in 1976 after a mighty season-long battle with Niki Lauda.

Here, in this new Haynes Manual, is unique perspective on what it takes to restore, maintain and race a McLaren M23, as well as an insight into the design, engineering and development of this landmark Formula 1 car.
