Lamborghini V10

Lamborghini V10 is a ninety degree (90°) V10 petrol engine which was developed for the Lamborghini Gallardo automobile, first sold in 2003.

This is only the third internal combustion engine developed by Automobili Lamborghini S.p.A.

for use in the Gallardo, and the first engine developed by the company after they were acquired by AUDI AG part of the Volkswagen Group.

As such, it shares components and technology from other members of the group, specifically Audi.

Its crankcase and cylinder block is built at the Audi Hungaria Motor Kft. factory in Győr, Hungary, whilst final assembly is at Sant'Agata, Italy.

Its 90° vee angle 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 sports car, based on the Audi Rosemeyer concept.[citation needed]

There was also some speculation that the engine block of the original 5.0 litre Lamborghini V10 is closely based on the Audi 4.2 FSI V8, which Audi produces for their luxury cars.

However, this was denied by AUDI AG, in their official documentation for their 5.2 FSI V10 engine, as used in the Audi S6 and Audi S8 - the Lamborghini 5.0 V10 has a cylinder bore spacing of 88 millimetres (3.46 in)

between centres, whereas the Audi 5.2 V10 cylinder bore spacing is 90 millimetres (3.54 in).

The cylinder heads use the four valves per cylinder layout favoured by the Italian firm, rather than the five valve per cylinder variation formerly favoured by the German members of Volkswagen Group - including Audi and Volkswagen Passenger Cars.

It was later confirmed by Stefan Reil of Audi's quattro GmbH subsidiary that the new 5.2 litre Lamborghini V10 does share

technologes with the Audi 5.2 V10 engine, as is evident by Lamborghini's usage of Audi's

Fuel Stratified Injection, and 90 mm cylinder spacing.
