in the aerospace industry, and the outcome was a fuel tank with an external Teflon coating which provides the fuel pumps with a constant supply of fuel in every situation, up to a residual capacity of three litres and maximum lateral acceleration of 1.4 G.
Tyres
For the Veyron, Bugatti worked in partnership with Michelin to develop the world’s first mass-produced tyre that can withstand speeds in the region of 400 km/h. The production tyres can be used for all speed ranges, which means that the Veyron does not require a different set of tyres when being driven at maximum speed. This was an important criterion which the developers had to fulfil in order to ensure the vehicle’s suitability for everyday driving.
One exciting detail of tyre development is the new tyre pressure sensor that had to be developed for the Veyron. Centrifugal forces of up to 130 kg are generated at speeds in excess of 400 km/h. This required extensive tests on a test stand used for aircraft gas turbines in order to simulate the high speeds of the Veyron wheels. At the time, this kind of system was not available in the automotive industry.
Brakes
Bugatti developed a high-performance braking system featuring many unique components in order to control the powerful forces effectively and bring the vehicle to a halt safely and quickly. Certain components were designed in conjunction with development partners from the aerospace industry.
Experiencing the Bugatti’s braking system in action is just as much of a thrill as the acceleration. Combined with the simultaneous application of the airbrake, an aerodynamic braking function integrated into the rear wing, the Veyron generates breathtaking deceleration values.
Bugatti chose carbon-ceramic as the preferred material for the brake discs, a Bugatti first, in order to achieve maximum braking performance and to withstand brake disc surface temperatures of up to 1,000 degrees. In addition, titanium was used for the brake disc hub instead of the usual stainless steel. As a result, the Veyron had by far the strongest braking performance in the automotive industry and motorsport at the time.
Variable aerodynamics
The Veyron’s design is an outstanding feature, which clearly sets the supercar apart from other high-performance vehicles. The shape and style of the Veyron are strongly based on the historical design DNA of the brand. The strict requirement to stick to the design of the car did not always make life easy for the developers, and this was also the case in relation to the aerodynamics, which are an essential element of a supercar.
The most important technical element on the Veyron in this regard is the rear wing. At speeds above 200 km/h it provides additional optimisation of braking performance. The wing flips up to an angle of 55 degrees in less than 0.4 seconds, with important consequences. Firstly, it increases the rear axle downforce, thereby improving the distribution of braking power between the front and rear axles. Secondly, it increases the air resistance, as when an aircraft is landing. At high speeds, the airbrake alone causes deceleration of up to 0.6 G. It is activated via the brake pressure. With standard tyres on appropriate road surfaces, the wheel brakes generate deceleration values of around 1.4 G.
