This Is Now the World's Fastest Car

The world has a new fastest car.

On Oct. 10, the reptilian SSC Tuatara hypercar posted an average speed of 316.11 mph (508.73 km/h) while driving on a seven-mile (11.27 km) stretch of two-lane Highway 160 outside Las Vegas. The result beat, by a large margin, two high marks set last year by Bugatti’s pre-production Chiron prototype (304.77 mph) and one that the Koenigsegg Agera RS set for production cars in 2017 (277.87 mph).
