Bugatti is building 30 examples of its record-setting Chiron for customers, dubbed the Sport Sport 300+.

While there has not been any official confirmation as yet, Instagram account Miller Motor Cars revealed an announcement was made during Bugatti’s Grand Fete 110th anniversary celebration at its Molsheim factory.

Driven by Le Mans legend and Bugatti test driver Andy Wallace, the Chiron Super Sport clocked a maximum speed of 490.7km/h (304.8mph) at VW’s Ehra-Lessien test track.

The Chiron Super Sport develops more power than the standard car, a whopping 1177kW/1600Nm from its 8.0-litre quad-turbo W16, the engine shared with the limited-edition Centodieci revealed recently during Monterey Car Week.

Bugatti engaged the help of motorsport experts Dallara to tweak the Chiron’s chassis and bodywork, resulting in an extra 25cm of bodywork at the rear which tapers heavily to reduce drag.

While the record-setting car ditched the passenger seat and incorporated a full roll cage in the name of protecting Wallace, customer cars will receive a full interior and run at normal ride height, rather than 25mm lower.

Pricing is set at US$3.9m (AUD$5.69m), a 30 per cent premium over the standard Chiron, but expect all 30 examples to already be spoken for.
