Geneva  - Swedish sports car maker Koenigsegg has joined forces with the Swiss NLV to build an all-electric, high performance super car with an output of 512 hp and a top speed of 275 kilometres an hour.

At the heart of the power package is the FAES battery system that can be charged from any electric plug in just 20 minutes with a range of 500 kilometres. The battery pack is positioned in the centre of the carbon-fibre monotube chassis.

Energy is supplied additionally by a recuperative braking system. An invisible, wafer-thin sheet of solar cells covers the entire bodywork, providing additional solar energy for the battery.

Despite its sporty character, the Quant provides space for four people and includes room for luggage. A three-zone air conditioning system provides the necessary comfort while three flat screen televisions offer entertainment.

The safety system includes six airbags, ABS (anti-lock brakes) and ESP (electronic stability programme). The car shown at the Geneva Motor Show is not a roll-out model, but works on prototypes and current serial production. However, Koenigsegg has yet to name a price saying it will be announced at a later date. (dpa)
