Bugatti couldn’t have its title challenged, and lopped on 200 more horsepower to make the Veyron Super Sport. Of the initial production run of 30 cars, five were branded the Super Sport World Record edition. When delivered to their owners, the electronic limiter held the cars to 257 mph. With the limiter removed, as tested and verified by Guinness World Records, all Veyron Super Sports could reach 267.86 mph. In 2014, a Hennessey Venom GT recorded a run at 270 mph, but only in one direction. Only 12 Venoms were produced, disqualifying it for the production car speed record by Guinness’s standards. Bugatti’s replacement for the Veyron, the brand-new Chiron, will be electronically limited to 261 mph. The ludicrous 1,500-hp Chiron will surely keep the crown with Bugatti, but so far the actual top speed has been a tightly kept secret.
