In 2005, Bugatti introduced the Bugatti Veyron Super Sport, which beat the speed record of the Dauer 962 LM. It accelerated from 0 to 200 km/h in 6.7 s and further developments with the 8 L W16 engine with four exhaust gas turbochargers achieved speeds of over 430 km/h.
In addition to the top speed, Bugatti has also adopted the self-supporting and rigid construction from motorsport for this vehicle. Thus, the Veyron Super Sport weighs 1,838 kg empty at a length of 4,462 mm.
The monocoque of the Veyron is the heart of the vehicle's architecture and is made of carbon prepregs. The sandwich structure consists of aluminium honeycombs to optimise the area moment of inertia. Combined, the two materials offer advantageous strength. Due to the high stiffness, the crash energy is almost completely absorbed in the front and rear structures, which consist of aluminium multi-chamber profiles. At the rear, there is a carbon structure that ensures the torsional stiffness of the Veyron up to the rear spring dampers.
In addition to the mechanical advantages, a monocoque is associated with increased manufacturing and material costs due to the design, choice of material and connection.
The Lightweighting Effect
The lightweight advantage of the monocoque is the better load distribution over the entire surface, so that a very high rigidity is possible despite the lower mass. This also leads to a high level of protection for the rider in the event of an accident. Weight savings result from the design itself, such as the integration of the tank, the optimised stress on the structure and an appropriate choice of materials.
