Turns out that the Bordeaux is in fact most likely a four-door, and Bugatti will be showing the car to existing customers to gauge their reaction and make sure the Bordeaux is the type of vehicle the company should be building. That said, Pfaegen wants to crush rumors that the Bordeaux will share parts with the new Bentley Mulsanne into dust. Says Pfaegen, "A Bugatti saloon will have different dimensions and be a completely different concept. In fact it's hard to find any similarities at all [with the Mulsanne]."
However, as both high end marques are owned by Volkswagen, we wouldn't be surprised if a bit of platform sharing took place beneath the surface. Whatever it is, the eight pipes lead us to speculate that high performance is the Bordeaux's raison d'etre. Especially as it will probably be packing the Veyron's quad-turbo, 8.0-liter 1,000+ hp W16.
We don't have any info on the other two concepts at this time, except that one of the three will indeed be Bugatti's next model. We'll go ahead and guess that one of the remaining two is Veyron 2.0. Especially as the Grand Sport Sang Bleu is the last of the special edition Veyrons. Plus, with 250 out of the 300 total Veyrons already built and sold, mega-performance hypercars might just be Bugatti's preferred niche. As for the possible third concept, we don't know. Though, if we were in charge of conceptual Bugattis, a new Royale would be in the works. If you have any guesses as to what the third Bugatti concept might be, shout it in the comments below.
