A 2.0-litre reduced-stroke version was also introduced in 1975 for sale in Italy, displacing 1,994 cc (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,[2] and the slightly updated replacement in 1982, the Lamborghini Jalpa, which saw the engine increased in size to 3.5 litres, displacing 3,485 cc (212.7 cu in),[2] for ease in meeting ever-tighter emissions requirements.
