If you've read the Guinness Book of World Records recently, you'll know that Koenigsegg's Agera R is fast. And very accomplished at stopping. But you probably don't know what the Swedish hypercar sounds - and looks - like when it's doing 402kph. Thankfully, there are men with camera phones to sate our curiosity.

Last week Koenigesegg got wind of an event on the Nurburgring and decided to take its Official Test Car, 7031 Streetfighter, plus the one that broke all the world records, to see what they could do on the Green Hell.

Click on the videoy bit and you'll see a standard Agera R pounding down the 3.5 kilometer Döttinger Höhe straight hitting 401.6 km/h (402kph in TopGear maths) before having to brake for the bridge at Tiergarten.

Reckon we should ski behind this Agera R, TopGear.commers?
