The new addition to the Chiron line-up shares its mechanicals - and most of its styling - with the Chiron Super Sport 300+, a limited-run special edition based on the specially adapted Chiron that achieved a record-breaking top speed of 304mph in 2019.
Unlike that car, however, the £2.75 million Super Sport places more of an emphasis on rolling refinement. Whereas the Super Sport 300+ was presented as a lightweight and mainly pace-focused affair, the new Super Sport stays true to the Bugatti tradition of "combining top speed with absolute luxury," according to president Stephan Winkelmann. It is, he claimed, "the ultimate grand tourer".
Chief among the design revisions over the standard Chiron are a bespoke front end and a 25cm-longer rear end that optimises aerodynamic efficiency. This, combined with a revised diffuser and EB110-inspired exhaust vents on the rear wings, helps to counteract the "immense" downforce enacted on the Super Sport at its 273mph top speed.
While the 30 production examples of the record-breaking Super Sport 300+ feature exposed carbonfibre bodywork, the new Super Sport is marked out by its more overtly production-focused, optional two-tone livery. Bugatti says this makes the car appear longer and "even lower".
The Pur Sport's lightweight magnesium wheels are an option, but the Super Sport is equipped as standard with a unique set of five-spoke aluminium items.
Inside, the Super Sport more closely matches the standard Chiron, with polished aluminium and leather used for most surfaces, along with elements of carbonfibre. Bugatti says it's "an interior perfectly suited to high-speed continental trips".
As with all other iterations of the Chiron, the Super Sport takes its power from a quad-turbocharged 8.0-litre W16 petrol engine, tuned to match the 1578bhp output of the 304mph car. Maximum engine speed is up 300rpm over the standard Chiron, at 7100rpm, while maximum torque - some 1180lb ft - is now available across a broader rev range.
