1934 Hispano-Suiza J12
As competition to the best that Bugatti, Alfa Romeo, Rolls-Royce, Bentley and Isotta-Fraschini could offer, the J12 in many respects was the superior design.
The centerpiece of every J12 was its locomotive-like 60˚ V12 which could produce 250 bhp no a good day. The 10-liter engine used a 70 lbs crankshaft held in seven main bearings. Spark was provided by 2 Scintilla magnetos and many ancilary pieces were cast from aluminum with very low tolerances.
Much of the chassis was over-engineered to achieve a near-silent operation noise ease of use. It had fully adjustable servo-assisted brakes and the tranmission was geared for the extreme torque made by the engine.
The J12 was one of the most expensive pre-war chassis, costing $10,150.
