Description

The P3 was the first genuine single seater racing car, and was powered by a supercharged eight-cylinder engine. The car was very light for the period, weighing just over 1,500 lb (680 kg) despite using a cast iron engine block. The P3 was introduced in June, halfway through the

Enzo Ferrari had to run his breakaway 'works' Alfa team as Scuderia Ferrari, using the older, less effective Alfa Monzas. Alfa procrastinated until August and missed the first 25 events, and only after much wrangling was the P3 finally handed over to Scuderia Ferrari. P3s then won six of the final 11 events of the season including the final 2 major Grands Prix in Italy and Spain. The regulations for the 1934 Grand Prix season brought larger bodywork requirements, so to counteract this the engine was bored out to 2.9 litres.
