The Hispano-Suiza J12 was a luxury automobile made by Hispano-Suiza from 1931 to 1938. It replaced the Hispano-Suiza H6.[1][2]
The J12 was powered by a V12 engine with pushrod-operated overhead valves.[1] The engine initially displaced 9.4 L (574 cu in)[2][3] with bore and stroke both being 100 mm (3.9 in) and, with a compression ratio of 5.0:1,[3] delivered 220 hp at 3000 rpm.[2][3] Two cars were fitted with long-stroke engines displacing 11.3 L (690 cu in) and delivering 250 hp, and several J12s were later upgraded to the larger engine. Each engine block was machined from a single 700 lb (318 kg) billet.[2]
Hispano-Suiza suspended automobile production in 1938 to concentrate on the manufacture of aircraft engines.[1]
