A Bugatti Chiron shod with original equipment Michelin Pilot Sport Cup 2 tyres has been the first, slightly modified, production car to break the symbolic 300 miles per hour* barrier.
Michelin original equipment tyres
“The challenge of breaking the 300 miles per hour barrier has long been an ambition in the automotive world. It is a speed that only few can imagine and which requires a very special vehicle”. It is with these words that Bugatti described its new speed record with a Chiron prototype on the Ehra-Lession test track in Northern Germany. Equipped with Michelin Pilot Sport Cup 2 tyres, the slightly modified supercar has broken the speed record, independently certified by TÜV. “We're overjoyed to be the first manufacturer ever to have achieved a speed of more than 300 miles per hour” said Stephan Winkelmann, President of Bugatti. “It is a milestone for eternity. I would like to thank the whole team and driver Andy Wallace for this outstanding performance”.
The Bugatti Chiron even reached a maximum speed of 304.773mph (490.484km/h). A performance made possible with a vehicle which is 25 cm longer, and with the rear wing, airbrake and passenger seat removed. The Michelin Pilot Sport Cup 2 tyres used for this record are very similar to those already available as original equipment on the production Bugatti Chiron. They are marked “BG” showing they are street legal for Bugatti. Only the belts of the tyres were reinforced for this record, to withstand the 5,300 g of acceleration. To develop these record-breaking tyres, Michelin used its Technology Centre in Ladoux, France as well as its site in Charlotte, USA. In America, test machines designed for the Space Shuttles were used to carry out tests up to 510 km/h.
“Michelin is very proud to have been an integral part of this record and it is the fruit of the relationship between us and Bugatti which stretches back almost 20 years”, said Pierre Chandezon, Bugatti tyre design team leader at Michelin. “With this in mind, it was the trust built up over this time that gave Bugatti the confidence to allow Michelin to develop the sole original equipment fitment tyres for the Chiron”.
American tyre manufacturer Goodyear has announced its return to the FIA World Endurance Championship (WEC) at the start of the 2019/2020 season. A new range of tyres has been developed for the occasion.
The Volkswagen ID.R has just set a new lap record at the Nurburgring Nordschleife (North loop) in the all-electric vehicle category. An exceptional performance achieved jointly with tyre manufacturer Bridgestone, revealing the overall change taking place in the mobility world.
