Koenigsegg One:1 debuts at Geneva with 1,341hp and 450km/h top speed
The Swedish marque used the 2014 Geneva Motor Show to unveil the One:1, claiming the 1,341kg, 1,341hp car is the world’s fastest production supercar.
Koenigsegg has revealed the One:1 at the 2014 Geneva Motor Show, presenting a car that aims to eclipse the Bugatti Veyron Super Sport as the world’s fastest production supercar. The Swedish manufacturer claims a top speed of 450km/h (280mph) and a power-to-weight ratio that gives the car its name: 1,341hp for 1,341kg. The One:1’s figures position it at the very top of the hypercar segment, attracting global attention at the Geneva event.

Performance and Powertrain
At the heart of the Koenigsegg One:1 is a 5.0-litre aluminium twin-turbocharged V8 engine. This powerplant generates 1,341hp (986kW) and 1,371Nm of torque at 6,000rpm, all delivered to the rear wheels. Koenigsegg’s target figures would put the car comfortably ahead of the Veyron Super Sport, which is officially rated at 1,200hp and a top speed of 431km/h (268mph). The One:1’s acceleration is equally dramatic: the company claims it can sprint from standstill to 400km/h in just 20 seconds, and then brake to a halt from that speed in only 10 seconds.
The car’s name, One:1, refers to its remarkable power-to-weight ratio: one horsepower for every kilogram of mass. This is made possible by a kerb weight of 1,341kg (2,956lbs) and a total output of 1,341hp. Such a ratio is unprecedented in a road-legal production car, and it underpins the One:1’s claim to the title of world’s fastest production supercar.
Technical Details and Construction
Koenigsegg has built the One:1 around a carbon fibre monocoque chassis, which contributes to its low weight and high rigidity. The use of carbon fibre extends to the wheels, with 19-inch rims at the front and 20-inch at the rear, all wrapped in custom Michelin Cup tyres. These tyres are specifically developed to handle the car’s extreme performance and provide the necessary grip at high speeds.
The suspension system features an updated triplex arrangement, utilising carbon bevel springs and active shock absorbers. This setup is engineered to maintain stability and control, even under the immense forces generated during acceleration and high-speed manoeuvres. Stopping power is provided by 397mm ventilated ceramic discs with six-piston calipers at the front, and 380mm ceramic discs with four-piston calipers at the rear. These high-performance brakes are designed to cope with repeated high-speed stops.
Aerodynamics and Electronics
Aerodynamic efficiency is a major focus for the One:1. The car is equipped with active aerodynamics, including a large adjustable rear wing and movable front flaps. These components work together to optimise downforce and stability, especially at the car’s claimed top speeds. The advanced aerodynamic package is essential for keeping the car planted on the road during extreme performance driving.
In addition to its mechanical sophistication, the One:1 features a suite of electronic systems. Koenigsegg has fitted the car with advanced traction and stability controls, tailored specifically for its unique performance characteristics. These systems help manage the car’s immense power and ensure that drivers can safely explore its capabilities on both road and track.
