Over the weekend, Koenigsegg achieved an impressive feat after shutting down an 11-mile section of Nevada's Route 160, between Las Vegas and Pahrump.
Video released by Racelogic, which recorded the speed, shows the Koenigsegg appearing to cruise up to 200mph before Lilja unleashes the car's full potential. Also driving the Agera RS, they recently broke the 0-400kph-0 record set just weeks earlier by Bugatti's Chiron.
There were even reports that the Koenigsegg Agera RS actually unofficially hit a top speed of 291 miles per hour, though in the two runs, the official fastest speed that the hypercar reached was 284.3 miles per hour.
Koenigsegg told Jalopnik the run was done on Michelin Pilot Sport Cup 2 tires, the same tires delivered to customers, and that Michelin reps were on-hand to make sure everything went ok.
We'll be there to bring you breaking news if the Venom F5 does manage to crack through that barrier.
Turnbull 'open' to NZ refugee offer
Australia withdrew from the Manus Island centre on Tuesday, following a PNG court ruling that the centre was unconstitutional. The other 10 countries would remain a matter for negotiations, but she said New Zealand was not the only one concerned.
Forget the Bugatti Veyron, the record for the fastest production vehicle has been smashed yet again.
But Koenigsegg's record may not last long as two rival hypercars look set to pose a serious challenge to the Swedish hypercar's title of world's fastest vehicle.
It turns out the Koenigsegg Agera RS is quite fast.
Before the Agera RS hit its new high, Guinness World Record recognised the Bugatti Veyron 16.4 Super Sport as the fastest production vehicle.
Koenigsegg's factory test driver Niklas Lija drove Agera RS with its 1,144bhp, 5.0-litre turbo V8 to set the new record.
