The Bugatti Chiron is supposed to be the new big dog in the hypercar world, so it was almost expected when a few weeks ago the automaker announced it’d set a world record for acceleration and braking with a Chiron that’d rocketed from zero to 400 km/h (248 mph) and back to zero in just under 42 seconds.

Less expected was that record being broken so soon, by Swedish rival Koenigsegg, which, compared to the heavily funded VW-backed Bugatti, is sort of an underdog, if that makes any sense when we’re talking about hypercars.

Just four days ago, the manufacturer made a similar zero-400 km/h-zero run in a 1,360-horsepower Agera RS in just 36.44 seconds, beating the Bugatti by five-and-a-half seconds. Goddamn.

Christian von Koenigsegg was planning on making a record run soon with the company’s new sold-out Regera, but a very keen new American Agera RS owner volunteered their car instead, explains Road & Track. Still wearing its protective shipping tape, the car did its usual 300 km/h (186 mph) test run on the factory’s track, and was then shipped to Vandel.

The one-time Danish Army Air Service base was Koenigsegg’s plan B; apparently plan A was a run at the Papenburg test facility in Germany at the beginning of the month, which was cancelled due to weather. Vandel’s 1.1-km (1.7-mile) runway gave Koenigsegg the room it’d need for the attempt, even if it was pockmarked with small potholes and offered relatively low grip.

Koenigsegg factory driver Niklas Lilja’s run October 1 is detailed in the video below; we’d expect it to be quite nerve-wracking for him, considering the car has never been tested at speeds like that before, never mind the low-grip concrete surface he was driving on.

But we have to admit we’re more than a little excited now the Chiron has some competition. Seems like the hypercar wars are just heating up.
