It would take a UGR TT car a long, long time to go around a Veyron SS from a dig (the race would be over by then IMO), but I think the UGR TT car would win from a roll. Of course, I’m talking about one of UGR’s top level packages.
The Veyron is like the GTR-it’s going to keep up with (and beat) cars that might have a better power to weight ratio because it shifts so fast and gets the power to the ground like none other.
