The production-spec Bugatti Chiron Super Sport 300+ has been spied during a recent round of testing as the French car manufacturer readies it to land in the hands of customers. It has been roughly 10 months since Bugatti shocked the world by announcing it had hit a top speed of 490.484 km/h in a Chiron prototype. Soon after, it announced the model that achieved this top speed feat was the Chiron Super Sport 300+, while revealing that production would be capped at just 30 units worldwide.

Bugatti has only previously shown the flagship variant of the Chiron finished in carbon fiber with orange accents, but this prototype has a matte black finish and sits on a set of dark red wheels. It is free of any camouflage and a host of testing equipment can be seen through the windshield.


Visually, the car looks identical to the prototype. The front features enlarged and angular new air intakes while there are also circular air vents on the front wheel arches. Bugatti has also fitted tweaked side skirts while also extending the rear-end of the car, effectively making it a ‘Long Tail.’ The rear also features a distinctive exhaust layout and a unique rear diffuser.

The only visual difference between this tester and the car previously shown by Bugatti is that this one has the Chiron’s available Sky View dual sunroof. It remains unclear if this will be a standard feature on all Chiron Super Sport 300+ models or an optional extra.

Like the record-breaking car, the production model will be powered by a quad-turbo 8.0-liter W16 engine rated at 1,578 HP. Prices start at € 3.5 million (US$ 3.96 million) and Bugatti intends on starting customer deliveries next year.
