A few months ago, Mr Koenigsegg dispatched one of his Agera R hypercars, a driver with a lead foot and a tracking box to a proving ground in Sweden. Said driver performed some lightly astonishing feats of acceleration. Six, to be precise.

He then wrapped these up into a little package and sent them off to the Guinness Book of World Records. If you have forgotten these times, they are as follows:

0-200 mph - 17.68 sec

0-300 km/h - 14.53 sec

200-0 mph - 7.28 sec

300-0 km/h - 6.66 sec

0-200-0 mph - 24.96 sec

0-300-0 km/h - 21.19 sec

That last one is significant. Yesterday, Mr Koenigsegg got the call from Guinness: “The fastest time for a two-seater production car to travel from 0-300-0 km/h is 21.19 sec, achieved by a Koenigsegg Agera R, driven by Robert Serwanski, at Angelholm airfield, Sweden.”

There you have it. It is officially a speed demon. With magnificent brakes.

Now watch the video. And then check out the time we took it to a frozen lake, with The Stig…
