With British racing legend Andy Wallace at the wheel, a tuned Chiron Sport hit a top speed of 304.77mph (490.47 km/h) at a test track in Germany, beating the previous record by nearly 27mph. That's the same place that Bugatti has previously set its 400km/h, 250mph and 0-400-0km/h records. That speed sets a new world speed record for a production auto. But unlike its Veyron predecessor, the Chiron has always been missing one key figure, indeed the figure that went on to define said earlier auto and was its underlying reason for being: an all-out top speed.
The first is a technicality. All land speed records require two runs on the same course in opposite directions, with the record being the average speed of the two. It might not hold it for long, as the Chiron's top speed is nearly 10% faster, but don't count the Swedes out just yet either. Koenigsegg has a tendency to not take these things lying down.
As you can see, this isn't your typical Chiron Sport. "It's to get everything together and working in one vehicle".
This specific Chiron also features a variation on the Veyron Super Sport's carbonfibre and orange livery, alluding to the fact that this auto is a record-breaker. Bugatti also ditched the airbrake and streamlined the rear deck to improve aerodynamic efficiency, redesigning the exhaust system and diffuser in the process. Bugatti will confirm more at a later date, but we do have images of the auto that broke the record and it does feature quite a wide range of modifications compared to the standard Chiron, all in the name of helping it achieve that record-breaking speed. For power, Bugatti has fitted an updated version of the characteristic eight-liter W16 engine. Top Gear says the car's gearbox and all-wheel-drive system are unchanged from the stock Chiron.
Although weight doesn't play that much of a role in top speed, Bugatti has shaved a few pounds here and there.
It's unlikely to feature the stripped-out single-seat interior or roll-cage but is likely to get the mechanical upgrades.
Ultimately it renders the 300mph Chiron a bit of a one-off. The Chiron ran perfectly and the track and weather conditions were ideal. A special and extremely limited edition based on this vehicle here would be an interesting way to cash out on the record-breaking run, don't you agree?
"Bugatti has once again shown what it's capable of", said Stephan Winkelmann, President of Bugatti. With this new record of the Chiron we enter again uncharted territory.
