Bugatti, Bugatti Veyron 16.4

The vehicle

In 2005, Bugatti presented the Bugatti Veyron Super Sport, which beat the speed record of the Dauer 962 LM. This accelerated from 0 to 200 km/h in 6.7 s and further developments with the 8 L W16 engine with four turbochargers achieved speeds of over 430 km/h.

In addition to the top speed, Bugatti has also adopted the self-supporting and rigid design from motorsport for this vehicle. With a length of 4,462 mm, the Veyron Super Sport weighs 1,838 kg empty.

The technology

The monocoque of the Veyron is the heart of the vehicle architecture and is made of carbon prepregs. The sandwich structure consists of aluminium honeycombs to optimize the moment of inertia. When combined, both materials offer advantageous strength. Due to the high rigidity, the crash energy is almost completely absorbed in the front and rear structures, which consist of aluminum multi-chamber profiles. At the rear, there is a carbon structure which ensures the torsional rigidity of the Veyron right 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 shape, choice of material and connection.

The lightweight aspect

The lightweight construction advantage of the monocoque is the better load distribution over the entire surface, which enables very high rigidity 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 optimized load on the structure and the appropriate choice of materials.
