Earlier in September, Bugatti showed off the Chiron's performance credentials by doing a 0-400 km/h and a 0-400-0 km/h run. During the run, the Chiron managed to do the former in only 32.6 seconds which. Futhermore it set a new world record for production cars by doing completing the latter task in a mere 41.96 seconds, with Juan Pablo Montoya behind the wheel. The record would not stand for long however, as a Swedish hypercar maker would also be targeting Bugatti's record.

Only a month later on October 1, Koenigsegg also set a 0-400-0 km/h run using the Agera RS which managed to do it in 36.44 seconds, beating the Chiron's time by 5.5 seconds. It also beat the Chiron's 0-400 km/h run by only taking 26.88 seconds instead of 32.6 seconds. Setting the record was Koenigsegg factory driver Niklas Lilja, which performed the run at Vandel Airfield in Denmark. In fact, Lilja manage to do a 0-403-0 km/h run in 37.28 seconds.

To confirm the times and data, Koenigsegg installed a data logger and GPS inside the Agera RS. Apart from adjusting the angle of the rear wing, the Agera RS was in its factory specification with the optional 1,341 PS engine upgrade, which still produces less power than the Chiron's 1,480 PS. To keep the driver safe, Koenigsegg also installed their removable roll cage specifically for the record run.

Koenigsegg smashes Bugatti Chiron's 0-400-0 km/h record run

Koenigsegg atttempted the record breaking run at the request of the Agera RS's owner, which wanted to compare the car's performance with other manufacturers. Following the run, this specific Agera RS will now be shipped to its owner in the United States.

Despite now holding the world record, Koengisegg thinks that they can still do an even faster run with the Regera, which they say is perfectly suited for this task. We can only wonder how long will Koenigsegg's record stand before it is beaten once again.

Watch as the Koenigsegg Agera RS goes from 0 to 400km/h and back to zero in video above.
