Perhaps an interesting sidenote not known by many:
To take the Veyron to its maximum speed you first have to press a special button in the Veyron´s cockpit requesting an online clearance by VW via satellite. Upon receipt of the request, VW technicians first check whether you´ve stuck with the mandatory service intervals or not. These, among others, require you to completely chance wheels and tires for a brand new set every 10000 kilometers, setting you back 30.000 EUROS each time.
When everything is O.K., a satellite signal is being sent to the Veyron´s engine management releasing the last bit of horsepower.
