It's nice, but didn't Bugatti build a supercar in the 90's called the EB110, with around 560 BHP and top speed in excess of 215MPH? From what I remember, it didnt do as well as they hoped. I think they are relying on the Bugatti name of decades ago, to carry it. When you come up against the likes of the Maclaren F1 or Ferrari then they will have their work cut out!
It does look awesome though!
