It uses a multi staged nitrous system that ads more power as it can tyres 
and grip allowing. Ie as the speed goes up and the gearing is increased it

just ads power that it cannot use at lower speeds. So effectively the rate

of acceleration is much more constant and continuous than the road car.
The 
road car veyron has less torque and power available at the wheels every
time 
it goes up a gear. The race car simply ups the power.

It does not accelerate faster and faster and I never claimed it did. But
it 
does compensate in power as speed and gearing increases wheras the veyron 
does not. It simply has less torque available at the wheels every time you

go up a gear. Thats why it takes about a week to get to its top speed in 
high gear.
Off the line it has huge weight transfer on to its rear wheels as the
excess 
extra energy from the reving 9 litre motor internals which are heavy and 
store a lot of energy. It does not break traction due to the weight
transfer 
that happens on chassis correctly engineered to allow the almost wheelie 
situation to occur. The effect of the pitching car is lost as soon as the 
first few yards are covered but then so is the extra energy already 
expended. So its not possible to add the 0 to 60 times together as the
first 
one has a big advantage in grip.

Sorry but all you proved is that your grasp of physics and drag cars is 
sadly lacking. Incidentally I am not the one cutting all the big chunks
out 
of the posts that I didnt like the answers to either...  Sadly thats the 
sign of desperation. I know you think the veyron is good and it is 
increadibly good for a civilised safe fast road car but in performace only

stakes it needs 3+ times more power to compete with the less civilised and

MUCH faster vauxhall. So much for you comments about the comparrison being

"laughable".  I have seen a maclaren F1 do a standing quarter (yawn) and a

veyron isnt much faster really. And only 25mph faster flat out. To compare

that to something that runs a 7 second quarter mile which assaults your 
senses and actually looks about 4x as violent is whats laughable.
