Hispano Suiza J12 (1935 -1938)

At the 1931 Paris Motorshow Hispano Suiza showed all new car with a big V12 engine, the J12. The engine was big in displacement only because the designers managed to built a compact engine using the know-how gathered building airplane engines. The overhead valvetrain was very advanced for its time with revolutionary features like natrium cooled exhaust valves.

The Barcelona based company was responsible for the building the chassis and drivetrain, seperate coachbuilders were responsible for the bodies. This resulted in many different looking J12s
