The fastest car in the world is, as of November 5th, 2017, the Koenigsegg. The car reaches an average of 277.9 miles an hour, which blows the Bugatti and the Hennessey out of the water. These two were the fastest cars in the world until November 5th. The Koenigsegg broke all the records officially on that day, and it has steadily been breaking records since it was introduced to the speedsters of the world. Even more impressive, the Koenigsegg has impressed the employees at the Michelin tire company.
The tires are the one most limiting factor when it comes to generating speed on a car because they can become too hot and generate enough excess heat that it slows the car down. Not the Koenigsegg; the tires weren’t even wearing as expected.
