If the claims that are being made about it are true, this is the fastest road car on Earth. Jeremy Clarkson took the oddly named Koenigsegg to the TG track to see if it's true. Driving for TV is one of the most brutal things you can do to a car. You have to go faster and harder than you thought possible. Then you have to do it again because the director thinks "more tyre smoke would be nice".

Thus, the TG test track is a killer; after a day there, most cars are carted away on lorries. So, no-one held out much hope for the Koenigsegg - it's a supercar, and supercars are notoriously brittle. And it's Swedish.
