Nothing serves to run, if you do not know how to stop. Such could be the car of the Bugatti Chiron which accelerates and brakes faster than its shadow. Last August, on the secret tracks of Volkswagen located in Ehra-Lessien. The Alsatian supersportive set a world record, accelerating from 0 to 400 km / h and then braking until complete stop, in just 41.96 seconds.
