Motore e trasmissione Lancia Flaminia 2500
1957 - 1961



The Lancia engine 813.00 was manufactured by Lancia from 1957 for the Flaminia sedan. The engine was strictly derived from that of Lancia Aurelia, which was the first V 60° six-cylinder mass-produced engine. The original design, nowadays widely used by many manufacturers, was developed in 1940s by Franco De Virgilio, head of the Special Studies and Patent Office at Lancia. In both Aurelia and Flaminia models the engine features an extensive use of aluminium alloy and it is coupled with a fine transaxle transmission, used for a better on-board mass balance in order to improve the vehicle dynamic performance. The Flamimia V6 engine underwent continuous development and remained in production in different versions (also for sport models) up to 1970.
