Swedish supercar specialist Koenigsegg has officially lifted the lid on its latest mid-engined monster, the One:1.

So named because its output in metric horsepower (1360PS) equals its weight in kilograms (1360kg), the One:1 has a power to weight ratio of exactly 1:1. That's unprecedented for a production road car.

To put that into perspective, a Supermarine Spitfire - the lightweight fighter that helped win the Battle of Britain - has a power-to-weight ratio of 1:1.55.

The Ariel Atom V8 comes close with a P:W of 1:1.09, but that car does so by sacrificing creature comforts like, say, a roof and windscreen.

How does the Koenigsegg One:1 achieve such an incredible power to weight ratio? By combining a lightweight carbon-fibre chassis that's around 20kg lighter than that of a Koenigsegg Agera with a tweaked and tuned version of Koenigsegg's familiar 5.0 litre twin-turbocharged V8.

Total power is an even megawatt (or 1000kW), which is 162kW more than the already blisteringly fast Agera R. Torque numbers aren't quoted, but Koenigsegg says the One:1 will hit 400km/h from rest in a scarcely believable 20 seconds.

Active aerodynamics will endow it with the grip to sustain 2G in lateral cornering force, and generate up to 610kg of downforce at 260km/h.

With the aero dialled back top speed is expected to be North of 440km/h, which would make the One:1 the world's fastest limited production car, soundly beating the Hennessey Venom GT.

The Koenigsegg will make its motor show debut this week at Geneva, and production will be limited to just six cars. And yes, they're all spoken for.
