Here it is, the new Lamborghini called the Estoque. It still is a concept but when Porsche is ready with their Panamera I guess Laborghini isn’t going to wait long.
The engine could be the V10 from the LP560-4 or a turbocharged V8 derived from the same V10. They even speak of a possible “extremely high-performance TDI”. Lot’s of questions, but at least we know how it looks like.
