The Koenigsegg Agera RS was driven in the desert around Pahrump, Nevada by factory test driver Niklas Lalja. The speed was tested taking into account average as per acknowledged standards while travelling in both directions so as to account for wind speeds. This was recorded not on the car's instrument cluster but on a separate Racelogic module (VBOX). Watch the video below.
Having accomplished this feat, Koenigsegg Agera RS has now broken the previous record of 2010 when Bugatti Veyron Super Sport clocked 430.89 kmph as was verified by Guinness Book of World Records.
The new Chiron claims to be capable of a top speed of 463 kmph, but to date has only clocked 420 kmph on video. The Chiron was put to the test driven by Juan Pablo Montoya speeding from standstill to 399.9 kmph in under 42 seconds over a distance of 8,600 feet. Koenigsegg put the Agera RS to the test accomplishing the same feat in 36.4 seconds and at 8,009 feet.
The Agera RS is powered by a 5.0 liter, twin turbo, V8 engine offering 1160 hp peak power. It ran on Michelin Pilot Sport Cup 2 tyres and its power and speed were undisputable as it crossed the 447 kmph speed this past weekend smashing Bugatti's record.
