Caption: Bugatti Veyron Grand Sport, Test Drive Sardinia, Italy, June 2009. The doors of the new Bugatti Veyron 16.4 Grand Sport are made of carbon fibre, and house an integrated longitudinal beam. In the event of an accident, this transfers the load from the A to the B-pillar, thereby dissipating impact energy. Foto:Kai-Uwe Knoth/ Bugatti Automobiles S.A.S
