The final edition of the Chiron Super Sport 300+* – built in honor of the model’s record-breaking 304.773 mph top speed run – has now been delivered, completing its production run of just 30 models. Breaking new ground in straight-line performance, this Chiron Super Sport 300+ is a masterclass in engineering finished – as with every other 300+ – with an exposed carbon fiber body and Jet Orange accents.
When the Chiron Super Sport 300+ – piloted by Bugatti’s Pilote Officiel Andy Wallace – smashed through the 300 mph barrier in 2019 the world stood to attention ; never before had a production car reached such speeds. It immediately occupied a spot in history and now stands as a marker in the quest for ever greater performance and speed. Following the world record success, during a celebration of Bugatti’s 110th anniversary, Bugatti committed to building 30 examples of the record-breaking car for customers, the last of which has now gone to its private home.
Christophe Piochon, President of Bugatti Automobiles, said: “In the long history of Bugatti, there are vehicles that come to define their era. The Type 35 transformed motor racing, the Type 41 Royale redefined opulence, the Type 57 SC set new standards for design, and now there is the Chiron Super Sport 300+, hitting speeds that were long thought to be impossible in a production car. Its achievements have secured it legendary status in the Bugatti history books, and we’re delighted to have seen all 30 examples of the Chiron Super Sport 300+ delivered to some of our most passionate customers.”
To achieve its uncharted top speed of 304.773 mph (490.484 km/h) the Chiron Super Sport 300+ had to reach beyond the extreme standards set by the Bugatti Chiron1 in terms of both power and aerodynamics. A re-engineered version of Bugatti’s legendary 8.0-liter W16 engine surpasses the Chiron’s power output by 100 PS, resulting in a total of 1,600 PS. Bugatti’s team of world-class engineers developed a new thermal management system for the hyper sports car’s engine and gearbox, as well as making refinements to the software governing the engine, gearbox, powertrain and turbochargers.
But power is nothing without stability, especially at speeds never mastered by a production car before. While it remains faithful to the timeless beauty of the Chiron’s design language, the Chiron Super Sport 300+ features a ‘longtail’ which extends the car by approximately 25 cm. This allows the laminar flow to pass over the body for a longer period of time, therefore reducing aerodynamic stall by more than 40%. Air curtains adorning the hyper sports car’s front corners disperse excess air pressure towards the car’s sides. Simultaneously, air outlets at the wheel arches and behind the front wheels guide excess pressure away from each wheel arch, reducing drag by also producing a small amount of negative lift.
The Chiron Super Sport 300+’s liberal use of exposed carbon fiber flows through into the car’s engine cover, and even the windscreen wiper, contributing to crucial weight-saving that helps the hyper sports car push the envelope of performance. Subtle touches, including the Bugatti ‘Macaron’ logo made of genuine silver and black enamel, add to the sense of exclusivity and rarity. Extremely light and strong magnesium alloy wheels are finished in a bespoke colour named ‘Nocturne’.
All 30 examples of the Chiron Super Sport 300+ are now delivered, each one of them a unique piece of automotive history as well as one of the fastest and most technically advanced cars in the world.
