Lamborghini has spent the last few weeks tantalizing us with teasers of its front-engine, four-door concept, but that comes to an early end today as a French website has unceremoniously revealed the concept we've been calling the Estoque.

The Estoque features a long hood and short rear deck, with horizontal headlights up front and a pair of big Reventon-style air intakes in the front bumper. The fender vents behind the front wheels are tucked into the car's character line that flows back until it hits those wide rear haunches. Thanks to those teasers we had already figured out what the rear end would look like, and all those guesses were fairly spot on.

The rumormills are telling us to expect the 560-hp V10 from the Gallardo LP 560-4 underhood, as well as all-wheel-drive. Though it's showing up as a concept at the Paris Motor Show tomorrow, the Estoque is said to be destined for production as early as 2010 to compete with the new crop of four-door coupes from Porsche (Panamera) and Aston Martin (Rapide). We'll have live shots from the official unveiling early tomorrow morning, so stay tuned.
