I had heard that factoid and must have mis-remembered it - apparently the true number is 100 MPH (i.e., the Veyron could theoretically beat the F1 to 200 if it gave the F1 a 100 MPH head start).
It isn't true:
"Lets start by laying a myth to rest. You probably know the story, the one where a Bugatti Veyron gives a McLaren F1 a ten second head start in a drag race and still pips it to 200mph. The way the tale is told, the Veyron heroically claws back the distance between itself and the McLaren until, at 200mph, it pulls level, eyes momentarily lock across the shuddering air space, and then its gone, thundering on towards its 253mph top speed. Utter cobblers.
True, an early factory prediction for the Veyrons 0-200mph time (sub 20 seconds) put it about 10 seconds under that independently recorded for the McLaren. But after 10 seconds the F1 is almost a quarter of a mile down the road and travelling at 130mph. Stupendous as the Veyrons acceleration is, it wont have caught the Macca when it hits 200mph. It might well be doing 200mph at the same moment, but it will be doing it in the F1s mirrors."

Even if it was true, it really wouldn't be as amazing as it sounds at face value. Both cars rocket so quickly to 100MPH (Veyron 5.8s, F1 6.3s), that that part of the race to 200 is practically irrelevant. The F1 was tested at 28seconds to 200, which means it took almost 3 and half times as long to go from 100-200 as it did from 0-100. Same thing with the Veyron, Road & Track tested it at 24.2 seconds to 200, which though quicker than the F1, still took over 3 times as long going from 100-200 than 0-100. If you do the math you will also see that an F1 won't get caught to 200 given a 100MPH head start. F1 100-200: 21.7 seconds, Veyron 0-200 24.2 seconds.
There is so much speculation on the that TG video its not even funny.
Not really sure why. I mean, who knows what TG did to make the race turn out the way it did. It doesn't really matter. There is ample real world test data out there about these 2 cars to leave no doubt that the Veyron should never have been trailing in that race at any point let alone get dusted by the F1 through roughly the first 1/4 mile. If the Veryon wasn't just outright handicapped, the easiest thing to assume is that the Stig is simply a far superior driver to Hammond which is why he won off the line, and then the technical dominance of the Veyron just took over after that and negated the driver advantage as the race progressed.
