Bugatti has broken the 300mph barrier

A modified Chiron hits 304.77mph at Ehra-Lessien

An exclusive reveal from Top Gear that Bugatti has smashed through the 300mph barrier. On 2 August 2019, Andy Wallace hit a vmax of 304.77mph in a modified Chiron at Ehra-Lessien, becoming the first hypercar to break 300mph.

Over the past six months, a team of engineers from Bugatti, Michelin and chassis wizards Dallara set about creating a car that can break the 300mph barrier. And what a car. This is no ordinary Chiron. First, there’s the way it looks. At 25cm longer, this Chiron has an elegant but menacing presence. Its purposeful intent is amplified by laser-controlled ride height, set significantly lower to reduce drag, giving the impression that the car is melting into the tarmac.

At the rear, the long tail with its reduced cross section (to aid aero and minimise drag) is punctuated by a pair of over-and-under shotgun tail-pipes (first seen on the Centodieci limited special).

To reduce drag, the rear wing and airbrake have been removed and replaced with a static unit recessed into the tail.

“The biggest challenge is to get the overall package right, not only design, not only aerodynamics, not only engine, not only tyres. It’s to get everything together and working in one car,” says Frank Heyl, the man with the most outrageous title at Bugatti – master of arts, head of exterior design.

Inside, the high-speed Chiron has been stripped of a passenger seat, replaced with myriad computer systems. There’s a full roll cage and a safety seat for the driver, and any number of visible and invisible weight-saving measures have been deployed.
