We know Audi will have a big hand in the Lamborghini Estoque. Lamborghini is Audi's responsibility in the Volkswagen Group, and Audi has a lot more experience at performance sedans than Lambo (which has none.) The only real question is how much German will this Italian car speak? According to Car and Driver, that answer may be quite a lot.

It's rumored that the Estoque will be built on Audi's modular-longitudinal platform, which is the base of a number of new models, including the current Audi A4 and A5, the next-generation A6 and A8, the forthcoming A7->ke1694, and the 2013 Volkswagen Phaeton. The sedan will feature all-wheel drive as standard (likely a version close to Audi's Quattro system.) The largest powerplant for the Estoque should be the 5.2-liter V-10 engine from the Gallardo LP560-4, which was developed by Audi.

The Lambo sedan is currently aimed at direct competition from its now corporate parent's own sedan, the Porsche Panamera. So just like the plans for the Porsche, the Estoque may as have a diesel or hybrid version ready to go by the time it appears in 2011 or 2012.
