Bugatti Breaks 300 MPH Barrier with Bugatti Chiron

A pre-production vehicle of a Bugatti Chiron derivative is the first hyper sports car to break the magic 300-mile-per-hour barrier (482.80 kph). At the same time, Bugatti has set a new TÜV-certified speed record with 304.773 mph (490.484 kph).

“Bugatti has once again shown what it’s capable of. With this new record of the Chiron we enter again uncharted territory. Never before has a series manufacturer reached this high speed,” says Stephan Winkelmann, president of Bugatti. “Our goal was to be the first manufacturer ever to reach the magic 300-mile-per-hour mark. We have now achieved this–making ourselves, the entire team and myself, incredibly proud.”

With this new world record, Bugatti will also withdraw from the competition to produce the fastest serial production cars.

“We have shown several times that we build the fastest cars in the world. In future we will focus on other areas,” says Winkelmann.

The record-breaking driver

Le Mans winner and Bugatti test driver Andy Wallace reached the top speed of exactly 490.484 kph (304.773 mph) on August 2, 2019, on the test track at Ehra-Lessien in Lower Saxony. 

“An incredible speed. It’s inconceivable that a car would be capable of this. But the Chiron was well prepared and I felt very safe–even in these high speed ranges,” says Andy Wallace.

He worked his way up to the top speed from 300 kph in 50 kph-increments to make sure all the conditions were right and the Chiron was optimally balanced in terms of lift and downforce.

“Even at the first attempt I felt this would work. The Chiron ran perfectly and the track and weather conditions were ideal. The whole team did a fantastic job,” says Wallace, overjoyed at the accomplishment.

After one lap to condition the Chiron, Wallace accelerated out of the north curve to 200 kph to reach top speed on the 8.8-kilometer straight. At a precisely defined braking point, he decelerated the Chiron back to 200 kph to drive through the south bend. He had a distance of two kilometers in which to do so.

I went at full throttle from the start for approximately 70 seconds. It was important for me to be out of the bend at 200 kph in order to reach top speed on the straight. That required the very highest level of concentration,” says the new record-holder. He covered 136 meters in one second.

It’s not the first time that Wallace has set a speed record: in 1998, the Brit reached a speed of 391 kph (243 mph) in at McLaren F1 on the same track, likewise setting a record.

The world record Chiron

For the world record, a team of engineers from various disciplines, under the direction of Bugatti’s Head of Development Stefan Ellrott prepared a pre-production vehicle of a Chiron derivative. In addition to aerodynamic improvements, the specialists attached great importance to safety. Wallace was held in place by six-point belts and protected by an additional safety cell.

The Bugatti team were supported by Italian race specialist Dallara as well as tire manufacturer Michelin.

Michelin has been Bugatti’s tire partner for many years and ensured the necessary grip and stability. The Michelin high-speed tires already used on the Chiron were again reinforced, particularly the belts to handle the 5,300 G, while still being street legal. After all, the tires rotate up to 4,100 times in one minute. The tires were subjected to extensive test bench trials at speeds of up to 511 kph in the USA. Rigorous quality controls even after production: each tire was X-rayed to optimize up to the smallest details. The world record car was only fitted with the Michelin Pilot Sport Cup 2 tires directly before the record run.

The record track

The Ehra-Lessien high-speed track in Lower Saxony is 50 meters above sea level. Unlike higher-altitude high-speed tracks such as in Nevada, however, this has certain drawbacks. Due to the higher air density, the vehicle has to apply more force, and at high speeds of over 400 kph, it runs as if were driving against a wall.

“Air pressure, air density and temperature are very important for high-speed driving and can make a difference of up to 25 kph, depending on the altitude,” says Ellrott. But the team opted for the test track in Ehra-Lessien nonetheless.

A world record attempt at such an extreme speed of over 400 kph always involves a certain risk. Everything has to be right–the car, the weather, and the track. Ehra-Lessien offers the greatest possible safety, which is why we opted for this track,” says Ellrott.

It is the only place in the world where the safety standards for high-speed tests are this high. The 21-kilometer three-lane highway is lined with crash barriers, and rescue services are available at the north and south ends. The carriageway was cleaned with special mats prior the road test in order to pick up stones and grit.

“Driver safety is our top priority. We did everything in advance to minimize the risk,” says Ellrott.

The record run was recorded by a sealed GPS box, the certificate was issued by SGS-TÜV Saar. So as of August 2019, Bugatti is the first manufacturer to produce a car that runs faster than 300 mph (482.803 kph)–at a speed of 304.773 mph (490.485).

It is not Bugatti’s first world record on this track with a Chiron. In 2017, former Formula 1 driver Juan Pablo Montoya drove a Chiron from 0 to 400 to 0 kph on this test track in 41.96 seconds–the shortest run up to that point. With the Veyron 16.4, Bugatti set speed records for production vehicles in 2005 and 2010, and in 2013 the Veyron Grand Sport Vitesse set the record as the fastest roadster.

“Now Bugatti was the first to exceed the 300-mile-per-hour mark. An incredible achievement that shows what the men and women of Bugatti are capable of.  But this was the last time for us. Bugatti was the first to exceed 300-mile-per-hour–its name will go down in the history books and it will stay that way forever,” says Winkelmann.
