Koenigsegg One:1 hypercar shown at Geneva

This is the Koenigsegg One:1, a 1,322bhp hypercar set to become the most powerful road car ever

The new Koenigsegg One:1 has been revealed. It’s set to become the world’s most powerful production car, packing 1,322bhp, and it's been shown for the first time at the Geneva Motor Show.

The Koenigsegg Agera design cues will be carried over to the One:1, which is based on that car, such as the small LED framed rear lights and oversized central exhaust. Most noticeable changes over other Koenigsegg models such as the Agera S and R is the addition of a huge rear wing supported by two fins emerging from the roof.

The One:1 name also bears some significance, as it refers to the power to weight ratio of the car. The 5.0-litre turbocharged V8 from the Agera now produces 1,322bhp (1,340hp), matching the kerbweight of 1,340kg. That means the One:1 will become the world's most powerful production car, taking the crown from the 1,300bhp SCC Ultimate Aero. 

The torque that the engine produces is staggering too: 1,371Nm at 6,000rpm. The One:1 gets a 7 speed dual clutch automatic gearbox and an electronic differential. 

This means the car can go from 0-250mph in around 20 seconds - and the huge ceramic brakes take it back to 0 in just 10 seconds.

It would appear Koenigsegg is gunning for the title of the world’s fastest production car, too – currently owned by the 1184bhp Bugatti Veyron Super Sport, which set a 267.8mph record. The tyres fitted to the One:1 are rated for up to 273mph - indicating that the car could be able to hit those speeds.

Just six Koenigsegg One:1 cars will be built, and there's no word on price yet - but don't expect it to be cheap.
