No it didn't, a heavily modified version won Le Mans, I think a heavily modified Veyron would decimate all at Le Man seeing as it is mainly straights.
The GTR was 85 kg lighter at 915kg, but the engine output was lowered to 600 bhp because of regulations.
The Veyron is a 2 ton car. You would need to remove 500kg just to get the same power/weight ratio. You would still have a disadvantage because of the lower aero dynamic grip/weight which would give *much* longer braking distances and poorer cornering.
And then you would have to pit every other lap for fuel and tires.
