Watch A Koenisgsegg Agera RS Slice 5sec Off The Chiron's 0-400-0 Time

That didn’t take long, did it? Less than a month after Bugatti declared the Chiron to be the fastest car from 0-400-0kmh (0-248-0mph), the firm’s feat has already been bettered by Koenigsegg. By over five seconds, in fact.

The Swedish supercar company’s weapon of choice was - as anticipated - the 1341bhp, 5.0-litre V8-powered Agera RS, and it did the whole run in an astonishing 36.44 seconds, 5.52 seconds faster than the Chiron.

Braking time was actually a little slower at 9.56sec (vs 9.3 for the Chiron), with the Agera making up all the time over the Chiron on the acceleration phase.

The run at Vandel Airfield, Denmark was in reality a smidge longer than 36.44sec, with the RS hitting 403kmh before driver Niklas Lilja applied the brakes. Factoring that in, the duration was 37.28sec - still faster than the Chiron. The car covered 2535 metres in total.

We’d say something akin to ‘your move, Bugatti’, but we’re not sure much can be done to overcome that five and a half second deficit…
