Sure, the Bugatti Chiron Super Sport 300+ may have gone quicker than any other standard production car before it (hitting 304.773 mph or 490.48 km/h in 2019), but in a straight line, this 2006 Ford GT is even faster.

The Ford GT you’re looking at has been owned by Johnny Bohmer since 2006 and has long been one of the world’s fastest road-legal cars. Indeed, Bohmer originally purchased it off the showroom floor with the intention of breaking the 300 mph (482 km/h) barrier in it. It has gone through multiple iterations over the years and while it’s unclear exactly how much power it currently has, there’s no denying that this thing is an absolute beast.

Bohmer and his team recently headed out to the Launch and Landing Facility at Kennedy Space Center, Florida to test out a new ECU that was recently installed into the car. The car was performing so well during the tests that Bohmer decided to pin the throttle to the floor for as long as he dared. When he finally lifted, the car had hit an extraordinary 310.8 mph (500.1 km/h). That makes this the fastest road-legal car on earth.

This isn’t just some stripped-out race car, either. Indeed, Bohmer’s Ford GT continues to have a functioning air conditioning system, electric windows, and a stereo. He regularly drives it near his home in Florida and even uses it to take his kids to school Yep, this is a 310.8 mph Ford GT built in 2006 that functions perfectly fine as a street car.
