After success of Ferrari’s 4-cylinder Mondial and Monza racecars, Ferrari developed their straight-six for use in the 121 LM. Displacement of these new 6-cylinders reached over 4400 cc, providing more horsepower and torque than its predecessors. The engine was given twin-spark ignition, 3 side draft Weber carburetors producing 360bhp.
These new six-cylinder Ferraris were all about speed, and their outright straight-line performance went straight after Mercedes-Benz and Jaguar. The body was hand made by the workshops of Sergio Scaglietti, which included a ladder-type steel tube chassis with a DeDion rear suspension and wishbones up front. Even today the design is striking and purposeful.
