Koenigsegg's Agera RS has become the world's fastest production car after setting the world record with a two-way average speed of 277.9mph.
The test was carried out on an 11-mile stretch of road between Las Vegas and Pahrump, that had been closed to the public.
Driver Niklas Lilja took it very slowly at first to warm up the tyres and engine before fully accelerating.
The footage shows the car getting faster and faster with such incredible pace that it seems to dance across the tarmac slightly. With just a slight movement of the steering wheel, it appears that the car instantly reacts.
On its first run, the £1.5 million Agera RS hit 271.1mph, reaching 284.7mph on its second run. The average of 277.9mph secured the record.
The Agera RS has a 5.0-litre twin-turbo V8 producing a staggering 1,380bhp. It's so fast in fact that it can accelerate from 0-249mph and back to 0 in just 36.44 seconds.
The Koenigsegg managed to beat the former record-holding Hennessey Venom GT's run by 7mph. However, Hennessey claims its latest F5 model might steal the crown from the Koenigsegg if it can reach its claimed 300mph top speed.
