Whoa, hold up a second. 406 km/h is 251.72 mph. That's insane.
The ACO classes (which are used by ALMS, FIA Sportscar, et al) don't really provide for a car such as this so I don't see it having a major motorsport career. I mean I guess it might somehow be able to get snuck into GTS but that's usually the realm of Vipers, C5-Rs, Ferrari Maranellos, Saleen S7Rs and such.
Oh and it's definitely not as pretty as the McLaren F1.
Any word on pricing and/or weight? I know it's supposed to have like four turbos and 1000 hp...
