The Alfa Romeo P3 is one of the Alfa Romeo entries the open record knows by name, and by little else. That is not nothing: a name in the catalogue is where a car's story starts to be recoverable.
The background
The Alfa Romeo P3, P3 monoposto or Tipo B was a classic Grand Prix car designed by Vittorio Jano, one of the Alfa Romeo 8C models. The P3 is considered to be the world's first genuine single-seat Grand Prix racing car and was Alfa Romeo's second monoposto after the Tipo A monoposto (1931). It was based on the earlier successful Alfa 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.
Where it sits
Its Alfa Romeo stablemates include the A.L.F.A 12 HP and the A.L.F.A 15 HP.
