Lamborghini V8

The Lamborghini V8 is a ninety degree (90°) V8 petrol engine designed by Lamborghini, for their less-expensive vehicles. It was only the second internal combustion engine ever developed by the company, and first saw production for the 1971 Lamborghini Urraco. It was designed by Gian Paolo Dallara. The all-aluminium alloy engine was introduced as a 2.5 litre variant, displacing 2,463 cubic centimetres (150.3 cu in), but was expanded, by increasing the piston stroke to a 3.0 litre variant for 1975 - now displacing 2,997 cubic centimetres (182.9 cu in).

A 2.0 litre reduced stroke version was also introduced in 1975 for sale in Italy, displacing 1,994 cubic centimetres (121.7 cu in), because of Italian legislation which imposed punitive taxes on cars whose engines displaced more than 2.0 litres.

This V8 engine was also used in two other models, the Lamborghini Silhouette in 1976-1977 in which it kept the 3.0 litre displacement, and the slightly updated replacement in 1982, the Lamborghini Jalpa, which saw the engine increased in size to 3.5 litres, displacing 3,485 cubic centimetres (212.7 cu in), for ease in meeting ever-tighter emissions requirements.
