|This is arguably the most elegant track weapon of its time. The Alfa Romeo P3 is of an era long gone by –a day when cars were built by artisans and those who drove them did so by the seat of their pants. This particular P3 was driven to innumerable victories by the great Tazio Nuvolari; whose racing accomplishments are the stuff of legend. There are a library of stories to tell of Nuvolari and the P3, but just climb aboard this astounding relic, fire up its twin-cam, twin-supercharged, aluminum straight-eight with hemispherical combustion chambers to instantly delight in the Renaissance days of racing. Be careful though; in this era, brakes were thought to be little more than added weight and the notion of “grip” was just something you did to a steering wheel. Consider yourself warned.|

The P3 was a single-seater, classic Grand Prix race car designed by Vittorio Jano. It was the first genuine single-seat Grand Prix race car.
The Alfa Romeo P3, based on the earlier Alfa Romeo P2, was powered by a supercharged 2.9L (2,905 cc) inline-8 engine. The car was very light for the time period, weighing just over 1500 lb (680 kg) despite the use of a cast iron engine block. With a power rating of 285 hp (213 kW), it delivered a large power-to-weight ratio of 380 hp (283 kW) per tonne for the time period.
In the 1934 Grand Prix season, the Alfa Romeo P3's engine was raised to 2,905 cc in displacement so as to counteract larger bodywork requirements brought forth by the 1934 Grand Prix season regulations. The P3s won 18 of all 35 Grand Prix events held throughout Europe.
