Ferrari caught the attention of everyone in motorsport when he won the 1952 “Mille Miglia” with the debutant 250 Smodel. To take advantage of this moment, the Italian house presented the Ferrari 250 MM at the Paris Motor Show as a celebration for the aforementioned victory.

The Ferrari 250 MM had a new, more standard chassis, especially for a sports car. The coupe bodywork version presented at the Geneva Motor Show in 1953 was designed and built by Pininfarina. The design was simple and traditional, without innovations. It looked like a small front grill, a moderate hood in length and a compact tail.

Vignale, a specialist in body design and with many Ferrari cars manufactured, presented a new 250 MM Barchetta with innovations such as built-in headlights and side vents. These traits would be adopted almost as design standards in Ferrari throughout the 1950s.

The Barchetta designed by Vignale had as main differences with the 250 S a longer wheelbase (2,420 mm), weighing only 850 kg. The engine no longer used dry crankcase although it was now more powerful, with 240 hp.

The Ferrari 250 MM was also a thoroughbred race. His debut on the tracks took place at the Giro di Sicilia being used by an unofficial team. Ferrari once again conquered the legendary “Mille Miglia” in 1954 with a 250 MM Barchetta designed by Carrozzeria Morelli. The winning driver was the Italian Clemente Biondetti.
