It seems that the folks at Bugatti cheated a little bit and the Veyron Super Sport is not actually the fastest production car on the market.
To be more specific, the Bugatti Veyron Super Sport is shipped with a top speed limiter which won’t let you go faster than 415 km/h. The specific unit used for breaking the world record had the speed limiter deactivated.
This let the Italian supercar to hit a top speed of 430 km/h, setting the record. The inquiry was made by the British people at Driving.co.uk with Guinness World Records approving their request and disqualifying the Veyron in consequence.
Of course, this does not mean that the Italian supercar is not able to hit that top speed but the rules say that the model tested should be exactly the same with the production version.
The Hennessey Venom GT is the next contender to the first place considering that it hit a top speed of 427.6 km/h on the Lemoore Naval Air Station in California.
