1972 McLaren M20
For 1972 Can-Am season, McLaren developed the M20 which took Denny Hulme to two victories in the Porsche 917/10 dominated series.
Compared the M8F it replaced, the M20 had a rear-mounted radiator which made way for a front-mounted air spoiler that dramatically increased from grip.
Unfortunately, the car’s massive 509 cu. in. (8,340 cc) Chevrolet engine was the main cause of retirements in the 1972 season, but offered an ample 750 bhp.
At the end of the 1972 season the Bruce McLaren Motor Racing M20’s were sold to privateers and continued to race. Denny Hulme took second place in the championship that year.
