It's a four-door built with the heart of a Gallardo and the body of a muscle builder to show a new opportunity for the company at the Paris Motor Show.

Full details will not be revealed until later in the week, but Lamborghini clearly intends to go up against the Porsche Panamera and Aston Martin Rapide in a coming battle for four-door supercars.

The car - the name will also be revealed on Thursday - is clearly American in concept and the basic shape could easily have come from the Chrysler catalogue.

But Lamborghini is promising an all-Italian inspiration for a car which will be capable of doubling the company's volume when it goes into production.
