The Lamborghini Estoque is said to share a platform with Audi A7.

More details are emerging on the Lamborghini Estoque four-door, set to debut in 2011 or 2012. Lamborghini insists the aggressive sedan is still only under consideration, but company insiders tell us Sant’Agata is already preparing the car for production. The only obstacle is a strategic review of the entire Volkswagen Group’s future vehicle portfolio, currently being carried out by Porsche, VW’s majority shareholder.

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 all-new A7, and the 2013 VW Phaeton.
