Taking lessons learned from that car, Jano went back to the drawing board to design a car that could last longer race distances. ==Description== [[File:2009-08-15 Monterrey Alfa P3 5006 Giddings.webm\|thumb\|left\|1932 Alfa Romep P3 s/n 5006 at Laguna Seca in 2009.]] 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,~~Introduced halfway through the European [[1932 Grand Prix season]] in ~~Europe~~June, ~~winning~~the P3 won its first race at the hands of [[Tazio Nuvolari]], and ~~going~~went on to win 6 races in total in that year, driven by both Nuvolari and [[Rudolf Caracciola]],. These victories ~~including~~included all 3three 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~~intended 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 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. Louis Chiron won the French Grand Prix at Montlhery, whilst the German [[Silver 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 the [[1935 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 the [[1935 German Grand Prix]] at the [[Nürburgring]], in the heartland of the [[Mercedes-Benz in motorsport\|Mercedes]] and [[Auto-Union]] empire. In the race, Nuvolari punctured a tyre early on while leading, but after ~~the~~his next pitstop he carved back through the field until the last lap when [[Manfred von Brauchitsch]], driving the ~~far~~more ~~superior~~powerful 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~~cementing its ~~place~~status as a truly great racing car.▼ ▲The P3 was introduced in June, halfway through the [[1932 Grand Prix season]] in Europe, winning its first race at the hands of [[Tazio Nuvolari]], and going on to win 6 races that year driven by both Nuvolari and [[Rudolf 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.
