The first production car, Tipo 105.64, was shown at the 1970 Geneva Motor Show and was quite different from the original, using a 2593 cc 90° dry-sump lubricated, cross-plane V8 engine with a bore of 80.0 mm and a stroke of only 64.5 mm and using SPICA (Società Pompe Iniezione Cassani & Affini) fuel injection that produced around 200 horsepower , coupled to a five-speed ZF manual gearbox and a limited-slip differential.
