Self-proclaimed 'megacar' builder Koenigsegg arrived at this year's Geneva Motor Show with a car capable of cranking out more than 1,500 PS. Called the Regera, it first debuted during the 2015 Geneva Motor Show as a concept model.

Compared to the concept car, Koenigsegg claimed they made over 3,000 changes on the car after putting it under a period of development, testing and homologation for the global market.

The Regera's exterior relatively carries over from the concept apart from some minor changes. Up front, it gets a tweaked hood and an updated headlight design. Over to the side, it gets new doors that feature a deep crease while the carbon fiber wheels have been retained for the production car. Like the headlights, the taillights get a slight reshape, as well as the Regera's exhaust pipe and diffuser.

Images of the Regera's interior were not provided but, Koenigsegg did confirm it features the latest in comfort and functionality. It gets rear and side door cameras as standard for ease of parking though there is an optional front-facing camera. This allows for a 'birds-eye' view of the car when parking in tight spaces or maneuvering around confined areas.

The seats are now heated and benefit from electric adjustment with memory function. In terms of infotainment, Apple CarPlay and Wi-Fi connectivity are now standard equipment in the Regera. This omits the need for a USB port according to Koenigsegg.

At the heart of the Regera is a 5.0-liter twin-turbo V8 that is helped along by three electric motors. It cranks out more than 1,520 PS along with a high torque output of more than 2,000 Nm. Power is then transferred to the wheels via Koenigsegg's 'Direct Drive System'. Unlike traditional transmissions, the 'Direct Drive System' eliminates weight, complexity and power losses according to the automaker. It makes use of a 'clutch-slip' system that uses the hydraulic coupling to convert power at high speeds.

With it, the Regera is capable of sprinting from 0 – 100 km/h in 2.8 seconds while 0 – 200 km/h comes in at a claimed 6.6 seconds. For those brave enough to plant their foot on the accelerator, Koenigsegg stated it can go from 0 – 400 km/h in just 20 seconds.
