Further evidence that Bugatti has a new product planned for its centenary celebration at the Frankfurt Motor Show this September comes by way of PistonHeads in the U.K., which offers up this image of the rear of what may or may not be a vehicle called the Bordeaux. Of course, before we pull this one completely out of the rumormill file, we'll need either official word from Bugatti or an actual picture of the party invitation that this car supposedly graces.

Assuming for a moment that this image is the real deal, we see some interesting tidbits from which to glean tantalizing details of the future car. While we're still not certain if this could be the World's Ultimate Sedan, some bizarre sort of shooting brake, or even a supercar to replace to Veyron (or none of the above), but the thin strip of brake light right down the center reminds us of the dorsal seam from the iconic Type 57SC Atlantic – certainly a fitting way to recollect the French automaker's first 100 years in business.

Note, too, the inclusion of eight rather obvious exhaust tips at the rear of the car, which reinforces speculation that this vehicle will be powered by Bugatti's current 8.0-liter W16 powerplant. If that's the case, we'd also expect the Veyron's all-wheel-drive system and active aerodynamics to keep the ridiculously powerful car from going airborne. As much fun as it is to speculate, we look forward to getting official word from Bugatti as Frankfurt draws nearer.
