We may never know how fast the Chiron is.

Bugatti has backtracked on its plans to set a speed record with the Chiron. Former Bugatti CEO Wolfgang Dürheimer previously announced plans to set a record with the French brand's latest creation.

Now Dürheimer's replacement Stefan Winkelmann has said that the company has no plans for a speed record with the Chiron for the time being.

'I have a lot on my plate. The speed test is not my priority,' he told CNBC. 'I think we have a lot of things to do.' When asked if it was possible that the Chiron may never be pushed to its limit, Winkelmann replied 'Maybe, I don’t know.'

Winkelmann also said that those who have put their name down for Chiron aren't even interested in the car's potential top speed. In fact, Bugatti themselves have no idea how fast it could possibly go. 'I know this for sure,' he insisted. 'I don't even know how fast our car can go.'

Strangely, the Chiron's predecessor wasn't too much of a sales success. The car which made history as the first road car with over a thousand metric horsepower and the first to crack 250mph, bettering the McLaren F1 which had held the world's fastest car crown for over a decade; but it took 10 years, four model variants, and countless special editions to shift all 450 cars in the production run.

Already more than 320 Chrions have found homes in under two years, with a waiting list of three years for the remaining 180 that are available. With that level of commercial success, Bugatti feels that it doesn't need to prove the Chiron's credentials in the same way it had to for the Veyron.

Officially, the Bugatti Veyron Super Sport is still the fastest production car in the world with a speed of 258mph, and retains that record due to its production number, but unofficially the fastest road-legal car is Koenigsegg Agera RS which reached a top speed of 277.87mph last year, but Koenigsegg says the car is capable of going even faster.

Currently, the Chiron is electronically limited to 261mph, but rumour has it the car could potentially break the 300mph barrier were it to have tyres up for the challenge – unfortunately, such tyres aren't thought to exist... yet.
