- Alfa Romeo P3
The Alfa Romeo P3, P3 monoposto or Tipo B was a classic Grand Prix car designed by
Vittorio Jano , one of theAlfa Romeo 8C models. The P3 was first genuine single-seat Grand Prix racing carCite web|url=http://www.ddavid.com/formula1/alfap3.htm|title=Alfa Romeo P3|accessdate=2007-09-04|work=ddavid.com] and Alfa Romeo's second monoposto after Tipo A monoposto (1931).Cite web|url=http://www.ultimatecarpage.com/car/3192/Alfa-Romeo-Tipo-A-Monoposto.html|title=Alfa Romeo Tipo A Monoposto|accessdate=2007-09-04|work=ultimatecarpage.com] It was based on the earlier successfulAlfa Romeo P2 . Taking lessons learned from that car, Jano went back to the drawing board to design a car that could last longer race distances. 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
1932 Grand Prix season in Europe, winning its first race at the hands ofTazio Nuvolari , and going on to win 6 races that year driven by both Nuvolari andRudolf Caracciola , including all 3 major Grands Prix in Italy, France and Germany.The
1933 Grand Prix season brought financial difficulties to Alfa Corse so the cars were simply locked away and Alfa attempted to rest on their laurels. Enzo Ferrari had to run his breakaway 'works' Alfa team as Scuderia Ferrari, using the older, less effective Alfa Monzas. Alfa prevaricated until August and missed the first 25 events, and only after much wrangling was the P3 finally handed over toScuderia 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. Louis Chiron won the French Grand Prix at Montlhery, whilst the GermanSilver Arrows dominated the other four rounds of the European Championship. However the P3s won 18 of all the 35 Grands Prix held throughout Europe. By the1935 Grand Prix season the P3 was hopelessly uncompetitive against the superior German cars in 6 rounds of the European Championship, but that didn't stop one final, legendary works victory. The P3 was bored out to 3.2 litres for Nuvolari for the1935 German Grand Prix at theNürburgring , in the heartland of the Mercedes andAuto-Union empire. In the race, Nuvolari punctured a tyre early on while leading, but after the pitstop he carved through the field until the last lap whenManfred von Brauchitsch , driving the far superior Mercedes Benz W25 suffered a puncture, leaving Nuvolari to win the race in front of 300,000 stunned Germans.The P3's agility and versatility enabled it to win 16 of the 39 Grands Prix in 1935. The P3 had earned it's place as a truly great racing car.
