The Maserati 8CM was one of the brand’s first Grand Prix racing cars. It was a particularly powerful car, with a 2,991.4 cubic centimetre straight eight engine capable of delivering 240 horsepower at 5,800 rpm in its most powerful version. This was 20 HP more than the original model; an upgrade achieved by fine-tuning its combustion system and other components. However, its weak point was the chassis, derived from the slender frame of the Maserati 4CM 1100 and too flexible to manage all the power of the eight cylinder engine, which initially impaired the car’s performance.
