The Bugatti Mistral just set the fastest open-roof road car record at 453.9kph
In case you’re keeping score, the Mistral wrenches the open-top record from the Hennessey Venom GT Spyder, which clocked 427.44kph way back in 2016...which wrenched it from the 1,183hp Veyron Vitesse, which recorded a 254mph run before that.
