Koenigsegg's One:1 megacar has arrived in Geneva together with its jaw-dropping 1,341 HP (986 kW) output.

Without any doubt the fastest car in Geneva these days is the Koenigsegg One:1 characterized by the Swedish maker as being world's first megacar since it delivers one megawatt of power (1,341 HP / 986 kW). The name comes from its 1:1 power-to-weight ratio so the vehicle tips the scales at just 1,341 kg (2,956 lbs).

Its beating heart is a vastly improved V8 5.0-liter twin-turbo from the Agera R which now pumps out a fantastic 1,011 lb-ft (1,371 Nm) and thanks to a wide array of aerodynamic tweaks the One:1 generates a whopping 610 kg (1,345 lbs) of downforce at 160 mph (257 km/h).

Koenigsegg says top speed wasn't a priority during development as the One:1 is more of a track-focused car but they anticipate it will be "world's fastest homologated production car" with a simulated top speed of more than 273 mph (440 km/h).

Only six cars will be made and obviously all of them have already been sold at a yet undisclosed price tag.
