Koenigsegg is teasing the One:1 supercar one last time ahead of a full reveal next week in Geneva.

[update] We attached two photos of the car taken at Koenigsegg's factory in Sweden.

Koenigsegg is teasing the One:1 supercar one last time ahead of a full reveal next week in Geneva.

Bugatti better watch out as Koenigsegg is bringing the One:1 to the Swiss show next week together with its impressive 1 bhp : 1 kg power-to-weight ratio from where it derives its moniker. The supercar will provide no less than 1,340 bhp (1,000 kW) in a 1,340 kg (2,954 lbs) body and will reportedly be able to hit a top speed of more than 280 mph (450 km/h).

According to company insiders, the One:1 will provide 600 kg (1,322 lbs) of downforce thanks to a huge rear wing and under cornering will generate more than 2G of later grip. Compared to the Agera, Koenigsegg's latest gem will feature revised active aerodynamics along with a rumored active chassis.

The Swedish marque has previously said the One:1 will be the fastest in the world in the 0-124 mph (0-200 km/h), 0-186 mph (0-300 km/h) and 0-248 mph (0-400 km/h) sprints. It will need just around 20 seconds to hit 248 mph from a standstill while the 280 mph (450 km/h) theoretical top speed will probably be capped by an electronic limiter because of tire limitations.
