The new Koenigsegg solar electric supercar manages 512 bhp, a 5.2-second 0-100 km/h time, and a top speed of 275 km/h, all without sacrificing a lengthy range.

Koenigsegg has released details on their new concept proposal, the Koenigsegg Quant. A four-seat solar electric supercar, the vehicle has been designed by the automaker and solar energy specialists NLV Solar.

A full-scale model of the car is on display at the Geneva Motor Show.

If it goes into production, the two companies forsee a car with a 500 km (311 mi) range, and batteries capable of a full charge in about 20 minutes. Those batteries would be a type that can be charged an unlimited number of times with no degradation. Keeping the range high is the thin film photovoltaic coating of the body, and the four-wheel brake regeneration.

The Quant would get the equivalent of 512 bhp and a wicked 715 Nm of torque, bringing the car from 0-100 km/h in 5.2 seconds. This power comes from a twin-motor setup only weighing 140 kg, and eliminates the need for a differential and bevel gears. Top speed of the Quant could reach 275 km/h. The rear-wheel drive car weighs in at 1780 kg

All four seats are adjustable, including the two at the back. Generous leg room in the rear means four adults can sit in the vehicle. Gull-wing doors and a lack of B-pillars let people get in and out all parts of the car easily. Those in the back will be entertained by the two "infotainment panels" integrated in the back. Another panel is in the front. Safety-wise, the vehicle has been designed with ABS, electronic stability, and six "smart" airbags.

Price of the vehicle is unknown, as is a potential production date.
