Koenigsegg’s Agera RS has become the world’s fastest road car, setting a new top speed of 277.9mph.
The Swedish hypercar actually hit 284mph on one leg of its record-breaking run but as timing purposes require the average of two runs its official figure is the only-slightly-less-mindboggling 277.9mph.
The Agera RS knocks into a relatively distant second the Hennessey Venom GT, which reached 270.49mph in 2014. The Bugatti Veyron Super Sport’s 2010 record of 269.86mph is now ancient history.
While Hennessey used a Space Shuttle runway and Bugatti their own Ehra-Lessien test track, the Koenigsegg completed its record-breaking run on a public road. An 11-mile stretch of Highway 160 between Las Vegas and Pahrump was closed so factory test driver Niklas Lija could take the customer car to its absolute limit.
To reach such ridiculous speeds, the carbon chassis hypercar is powered by a 5.0-litre, twin-turbo V8 which produces a staggering 1341bhp and 1,011lb/ft.
The Agera RS’s top speed is spectacular but there’s a shadow on the horizon – the Bugatti Chiron. So far the Chiron has been limited to 261mph due to concerns over tyre durability. Once Michelin figures out the rubber, expect the 1,500bhp Bugatti to be gunning hard for the Koenigsegg and potentially a top speed starting with a 3.
