Vittorio Jano along with Colin Chapman could arguably be called the greatest race car engineer in history. Born in 1891, he joined Fiat at the age of 20. alfap3b.jpg (9247 bytes)Working as a junior draughtsman under Carlo Cavalli, the brilliant head of the Fiat design section, he eventually became head of the design team in 1921. While at Fiat he worked along side its test driver Luigi Bazzi. It was Bazzi who had left Fiat to join the newly formed Alfa Romeo, who recommended his former associate. Alfa Romeo's car the P1 turned out to be a big disappointment and Jano was hired in 1923 to design a completely new car from scratch. That car was the P2 which won its first race in 1924 and continue winning races for the next six years in one form or another. alfap3a.jpg (17426 bytes)The 1932 season would be fought without the German cars from Daimler Benz. It would also be one with an open formula which limited only the length of the races to five hours. Building upon the lessons learned with the P2, Jano created the P3. The P3 Monoposto was the first genuine single-seat racing car in Grand Prix racing. It was powered by an eight-cylinder engine built around two four-cylinder blocks, each fed by its own Roots supercharger. One of the engines major strengths was its low-speed torque. Power to the rear wheels was transmitted through twin driveshafts that allowed for the drivers seat to be placed lower in the chassis. The original leaf spring suspension was replaced in 1935 by an independent Dubonnet front suspension. The complete car weighed in at only 1,545 lbs. and were it not for its cast-iron block engine, it would have weighed considerably less.

With the two best drivers of the day, Nuvolari and Caracciola racing them 1932 was a successful year. Some said that with a Jano designed car and their two great drivers they should not expect anything less. Financial troubles that had come to a head in 1933 saw the factory hand over racing to the Scuderia Ferrari team after going missing at the beginning of the year. Losing some of their initial superiority they still continued to wrack up victories later that year. 1934 found a new formula and new rivals from Germany. In the face of this Teutonic onslaught even Jano's Monoposto could not stem the tide except for one race that has come down through the ages.  The P3's most famous victory came very late in its career when Tazio Nuvolari beat the combined German might of five Mercedes and four Auto Unions. That race, the German Grand Prix at the Nurburgring, in front of dozens of Nazi officials is considered one of Nuvolari's greatest victories of all time while the car that took him to victory, the P3 is enshrined in the pantheon of great Grand Prix cars.
