Faster around a handling circuit... yep, that's what the Chiron needed to be.

If there's one thing Bugatti knows how to do, it's speed. The Veyron was fast, the Veyron Super Sport was faster and then, just when you thought there was no more 'fast' to go around, the Volkswagen Group's performance darling unveiled the Chiron.

Now, the fastest Bugatti has been made faster around a circuit, thanks to a strict diet and a new Sport badge. Unveiled in Geneva, it's a full five seconds faster than the standard Chiron around the Nardo handling circuit in Italy.

That quicker lap time comes courtesy of an 18kg weight saving – thank lightweight wheels, carbon-fibre stabilisers, a carbon intercooler cover and carbon-fibre windscreen wipers, along with a new rear window and exhaust deflector – and a handling package.

The rear-axle differential has been "optimised" for sharper handling, there's a new Dynamic Torque Vectoring function capable of actively shuffling grunt from side-to-side to "improve the steering behaviour and agility" of the Chiron. Bugatti says the shock absorbers are 10 per cent stiffer than stock, too, provided the car is running in Handling Mode.

In 'EB Mode' the Sport should behave just like its (slightly) less-focused stablemate.

Power comes from the same quad-turbo W16 engine you get in the standard Chiron, making the same 1103kW and 1600Nm. The 100km/h sprint blows by in 2.5 seconds, and top speed is limited to 420km/h to protect the tyres.

You'll be able to tell the Sport from the Chiron by its new alloy wheels and quad-pipe exhaust setup. As you'd expect, the paint job can be customised to the owner's desire, and there's a mind-boggling array of trim choices on offer.

Base price is predictably eye-watering: €2.65 million in Europe, or US$3.26 million ($4.2 million) including transport, customs costs, taxes and fees. Deliveries are set to start at the end of 2018.
