A ROAD car has broken the 300mph barrier for the first time — with a Brit behind the wheel.
Test driver Andy Wallace, 58, hit 304.77mph in a modified £2.5million Bugatti Chiron in Germany.
Wallace, from Oxford, a former Le Mans champ, saw the record fall on his GPS display but it was minutes before the pit crew knew.
He said: “They couldn’t work out why I was so happy on the radio.”
It took six months to prepare the car, with aerodynamic tweaks and the upgrading of its 8.0-litre, quad-turbo W16 engine — nicknamed Thor — from 1,479bhp to 1,578bhp.
It equals the power of 18 standard VW Golfs.
It is believed the changes will be included in a celebratory limited-edition model to be sold alongside the “normal” Chiron, which is limited to 261mph.
The record run on a five-mile straight section of the VW Group’s secretive Ehra-Lessien test track came after four days of testing.
The previous high speed stood at 277.87mph, set in a Swedish Koenigsegg Agera RS.
Bugatti President Stephan Winkelmann said: “With this new record of the Chiron we are in uncharted territory.
“Our goal was to be the first manufacturer ever to reach the magic 300mph mark and we have now achieved this.
“We have shown several times that we build the fastest cars in the world. In future we will focus on other areas.”
