Koenigsegg One1


The iconic One:1 is the first homologated production car in the world with one megawatt of power, crowning it the world´s first production megacar. The hp-to-kg curb weight ratio is an astonishing 1:1 – the “dream” equation, previously thought impossible in road-legal sports cars. Thus, the name One:1.

The One:1 truly raised the performance bar, featuring new unique solutions that enhance track performance and top speed while never straying from everyday usability and stunning looks.

of the One:1

Christian von Koenigsegg explains how his team has developed the new Koenigsegg One:1 5.0-liter twin-turbocharged V8 engine which produces 1,360 hp and 1,371 Nm (1,011 lb-ft) of torque at 6000 rpm. The total weight of the engine is only 197 kg (434 lb) thanks to a carbon fiber intake manifold and aluminum construction. The transmission is a 7-speed dual-clutch with paddle shifters.
