Pete, the SLR weighs in about 200-250 pounds less than the Bugatti at 3898 lb.

My assumptions are this: the video shows a rolling start, which means the issue of scrolling up turbos is pretty much gone. One car drives two wheels, one drives four. One has 40% more horsepower, and both cars are geared and aimed to hit 200 or more MPH so the gearing is pretty similar.

Net net, 400 more horsepower (1001 to 600) versus curb weigth (4100 to 3900) gives the bugatti a significant advantage. Only 4 pounds per HP to pull around, versus 6.5 pounds per pony in the SLR. Not slouch numbers on either side but still a real issue (for comparision, my GTI, which isn't a slow car, is moving 16 plus pounds per HP). When you consider the gearing is similar and all, that near 40% advantage in the P/W ratio is really hard to overcome. In theory, the SLR would have to get down to around 2500 pounds to have a hope in a straight line, and that would entirely depend on their ability to get any grip at that level. With the 4 wheel drive, the Bugatti is in a better position to put more power to the road with less weight because they are less likely to light'em up.
