Gallardo's v10 made by Audi?

[sakis]

Does anyone know which parts of the Gallardos v10 engine are made from Audi and which from lambo?

I read that they use the same block with 4.2-litre V8 FSI.

Strictly speaking, this is the first production V10 that Lamborghini has ever fitted to one of their automobiles, aside from the Cala concept. Most small Lamborghinis have either utilized a V8 engine, or a small V12. This is breaking new ground for the Italian marque. But, the thing to note here is that this isn't a full Italian work of art. Though most of the engine was thought up and put on paper by Lamborghini, Cosworth did a lot of the development. Come to think of it, this too is a first for Lambo; rarely if ever would this company search outside their own borders for 'help'. Most of what's been added by Cosworth can be traced back to Audi-esque technology found in most of their engines. The backbone of the engine is standard issue for Lamborghini - a powerful engine, and four valves per cylinder (hence Quattrovalvole the Countach.) Oddly enough, the engine uses an angle of 90°. In a V10, this means that the engine will have a lower center of gravity and is something that has been pulled right from super high tech Formula One cars. Not as high-tech is the dry-sump lubrication, which too lowers the c-of-g. New additions, such variable valve timing on both intake an exhaust valves can all be found in the new 5.0 liter V10 engine. As if this weren't enough, to keep the performance up, there are variable intake manifolds. Truly, as if it took nearly next to no effort on Lamborghini's part, the engine shoots out a whopping 500 horsepower, created at 7800 revolutions per minute. The direct competitors to the Gallardo - Porsche 911 Turbo, Ferrari 360 Modena - pale in comparison with 50 and 100 horsepower deficits. The big engine also comes out on top where it concerns torque. The maximum torque output is rated at 376 ft-lb, which seems to be a low compared to today's best. But as you know, figures on spreadsheets rarely tell the full story and in this case, it's the part about the Gallardo's V10 creating 80% of its maximum torque at just 1500 rpm.
