World's first Megacar

The One:1 was introduced in 2014. Seven examples, including one prototype, were built during 2014 and 2015.

This was one of the most exclusive production car programs ever envisaged in the car industry.

The hp-to-kg curb weight ratio is an astonishing 1:1. This is the “dream” equation, previously thought impossible when it comes to fully road legal and usable sports cars. The One:1 is the first homologated production car in the world with one Megawatt of power, thereby making it the world´s first series produced Megacar.

Thus, the name One:1.

The One:1 truly raised the performance bar. The One:1 featured new, unique solutions that enhance track performance without compromising top speed or everyday usability, with a stunning visual appearance to go with it.

Examples of features: unique track-optimized aero winglets, extended venturi tunnels and side splitters, Le-Mans inspired active wing configuration and optimized active under trim air management. Large air vents for improved cooling, roof air scoop to support the 1 Megawatt of power, 8250 RPM rev limit, complemented with custom-made Michelin Cup Tires, upgraded rear Triplex suspension with carbon bevel springs and active shock absorbers and ride height, combined with upgraded revolutionary Koenigsegg Aircore carbon fiber wheels.

Koenigsegg was the first extreme car manufacturer to take steps toward green technology with the release of the biofuel CCXR in 2007. The One:1, a sibling of the highly competitive Agera R, follows in the footsteps of the CCXR as it also runs on E85 biofuel, race fuel or normal gasoline.
