Bugatti will unveil a new ultra-exotic four-seater at the upcoming 2009 Frankfurt Auto Show.

According to Britain’s Auto Express, the supercar will be called the Bugatti Bordeaux.

The magazine said the long-rumored four-seater — known until now as the Royale — will share the Veyron’s quad-turbo 8.0-liter W16 engine.

With nearly 1,000 horsepower on tap, the Bordeaux should be the world’s fastest four-seater.

The car is expected to feature a shooting-brake-style body with a split rear window, horseshoe-shaped taillamps and central brake light — features that are barely discernible in the grainy image.
