Don’t forget to use the Speed Key!

The Bugatti Chiron might not be the fastest production car in the world, this prize goes to the Chiron Super Sport 300+ at 304 mph, but it’s still amazingly fast at a 261 mph. The fact that it ranks fifth in our The 10 Fastest Cars in the World Ranked speaks volumes about what it can do in standard form. And the cool thing is that any owner has access to that mind-boggling benchmark through the car’s special Speed Key. And race car driver Andy Wallace, the man who hit 304 mph in the Chiron Super Sport 300+, demonstrates how to use it.

The Chiron is normally limited to 236 mph, but Bugatti provides a key that enables you to go past that limit and up to its true top speed of 261 mph. All you have to do is insert this key into its special holder and wait for the car’s computers to do some checking to make sure it’s safe to hit that speed. Once that’s done, it will display "Top Speed" in the instrument cluster display, and you’re set to go.

The Chiron needs less than 40 seconds to hit its top speed, but it will also slow down in complete safety thanks to its advanced braking system.

Assuming you’re already the lucky owner of a Chiron, all you need now is a really long strip of tarmac to try it out.
