The 1:1 power-to-weight ratio in the new Koenigsegg means its 1340kg weight matches its 1340hp output
A top speed of 273mph is claimed
Koenigsegg celebrates its 20th anniversary in 2014
Cabin will no doubt feature plenty of carbonfibre to keep weight down
Active downforce measures on the One:1 include independent left and right flaps
The One:1 is so called as it has a power-to-weight ratio of 1:1 – it weighs 1340kg and produces 1322bhp (or 1340 metric horsepower). This power output figure eclipses the P1, LaFerrari and 918 Spyder, and also that of the 1184bhp Bugatti Veyron Super Sport.
The new model from the Swedish supercar firm is derived from the Agera R, which itself boasts a 1100bhp twin-turbocharged 5.0-litre V8. For the One:1, a claimed top speed of more than 273mph is quoted, which would make it the fastest production road car in the world – faster than the 270mph Hennessey Venom GT and 268mph Veyron Super Sport.
Koenigsegg claims this top speed is possible thanks to the One:1’s “high power and high-rpm capability in combination with strong tyres and active aero”.
Koenigsegg, which in 2014 celebrates its 20th anniversary, has equipped the One:1 with a carbonfibre chassis that's 20 per cent lighter than the Agera R’s, active aerodynamics, active ride height, variable-stiffness suspension, upgraded tyres, a lightweight titanium exhaust and a variable turbo housing to boost low-end torque.
The active aero consists of independent flaps left and right under the front splitter and a hydraulic dual-plan rear wing. This helps the One:1 produce 610kg of downforce at 160mph, which is equivalent to that of a McLaren P1.
Other impressive numbers include the car’s ability to pull 2g while cornering on road-legal tyres, and the ability for the Predictive Active Chassis and Aero Track Mode systems to be informed by 3G and GPS connectivity.
The car can record lap times and telemetry through an iPhone app, which is also able to receive software updates for the car.
Koenigsegg has not released a price for the model, but has confirmed that all examples of the One:1 have already been sold.
