The Veyron 16.4 is the fastest production vehicle of all times.

The car documents state a maximum velocity of 407 km/h, but that’s an understatement. On April 19, 2007, inspection officials recorded a top speed average of 408.47 km/h. For years, the Bugatti engineers had worked diligently in order to push the 400 km/h boundary. No wind tunnel can simulate this velocity, which is why after each of a long series of improvements, the different ground clearance levels and the modifications of the rear fenders, spoiler and underbody were tested separately on high-speed test ranges. This ambition and diligence paid off, as the official speed measurement proves.

The Veyron’s high velocity is due to the perfect combination of engine technology, consistent lightweight construction, specially developed tires, and the complex balance of propulsion and downforce. For not only the aerodynamic drag is a crucial factor at very high speeds, but also the precise adjustment of the downforce that holds the car to the road surface. And in addition to all this, the Veyron production vehicle meets the highest safety, reliability and maneuverability standards of even the most discerning drivers.

To create the optimum aerodynamics, the Bugatti engineers developed three configuration modes. In standard mode, used for speeds up to 220 km/h, the rear spoiler system is completely retracted. In handling mode, used at higher velocities, the vehicles nose is pulled down and the monumental rear spoiler deployed. This produces an additional 350 kg of downforce without compromising the Veyron’s exceptional turn dynamics. And then there is the top speed mode for velocities beyond 375 km/h, which is activated before the engine is started. At top speed mode the front diffuser flaps are shut to make the underbody absolutely level, and the spoiler is completely aligned with the chassis, forming a tearing edge – thus, the Veyron is perfectly adapted for top velocities. The downforce is reduced to minimize the strain on the tires, which is already considerable. The car is held down on the road by its own weight and the downforce. The Veyron starts immediately at top speed mode, allowing only for a limited turn of the steering wheel. As soon as the driver brakes, the Veyron automatically switches to handling mode. But those who dare to accelerate consistently on a long, straight road will experience the power of the fastest production vehicle of all times.
