Why it matters

The 375 Mille Miglia used a development of the Formula 1 engine, with a new crankshaft giving a 68 mm stroke and a larger bore for 4.5 litres. After it debuted in a 340 berlinetta at Le Mans, Pinin Farina built a series of about ten spiders and a few berlinettas, mainly raced by privateers. This note concerns the model, not this individual car.
