Lamborghini V10

From Wikipedia, the free encyclopedia

The Lamborghini V10 is a petrol engine which was developed for the Lamborghini Gallardo automobile, first sold in 2003.

This is only the third engine developed by Lamborghini, and the first engine developed by the company after the they were acquired by Audi AG - part of the Volkswagen Group (Volkswagen AG) (VWAG). As such, it shares components and technology from other members of the group, specifically Audi. Its block is built at the Audi Hungaria Motor Kft factory in Győr,[1] while final assembly is at Sant'Agata.[2] It is a 90° V10 which is unusual for this particular configuration of cylinders. It was chosen to keep the center of gravity of the engine low. For the same reason, a dry-sump lubrication system was also used.

There is speculation that this engine will also be fitted to a planned Audi RSR supercar based on the Audi Rosemeyer concept.[citation needed]

There is also speculation that the engine block of the V10 is closely based on the 4.2 litre V8 Audi produces for their luxury cars, though the cylinder heads are unique to Lamborghini, using the four valves per cylinder layout favoured by the Italian firm rather than the five valve per cylinder variation used by the German members of VWAG - including Audi and Volkswagen.[citation needed]
