Earlier last month, Koenigsegg set their sights on speed records and managed to smash the Bugatti Chiron's 0-400-0 km/h record using an Agera RS. However, it seems that the Swedish supercar marque was not yet done as it has just set a new world top speed record for a production car, managing to hit a top speed of 458 km/h in one pass.

Setting the record for Koenigsegg was the same Agera RS, which was used to beat the Chiron driven by factory test driver Niklas Lilja. In order to perform the top speed record run, the Swedish marque had a 17.7 km stretch of the Highway 160 in Nevada, USA closed by local authorities, giving the factory-spec Agera RS more than enough road for to max out its speed.

The number Koenigsegg needed to beat was the 434 km/h average speed set back in 2010 by an unrestricted version of the Bugatti Veyron Super Sport. The Agera RS managed to record an average top speed of 444.6km/h, which has been verified by Racelogic. The run needed to be done twice in opposite directions as per Guinness' World Record requirements. The Agera RS managed to hit 458 km/h in one direction and 436.44 km/h in the other due to an uphill gradient and a strong headwind.

Tires were a big factor during the run given the speeds Koenigsegg was hitting. However, no special tires were used during the record attempt. In fact, the Agera RS ran the same factory Michelin Pilot Sport Cup 2 fitted standard.

Given that Koenigsegg beat both Bugatti and Hennessey's top speed records, expect these two to roll out more powerful versions of their respective supercars and attempt to beat the record in the near future. The latter has already revealed a new contender called the Venom F5 and is going a claimed top speed of 484 km/h.
