The four-seat, 600 kW solar-powered Quant will come back to Geneva next week, in updated form. The story inside.

NLV Solar will be bringing a version of the Quant back to the Geneva Motor Show next month.  The solar electric car was built out of a partnership between NLV and Koenigsegg, and debuted last year in Geneva under the Swedish supercar maker's moniker.

Built with a photovoltaic coating, the surface sends solar energy to the "Flow Accumulator Energy Storage," a fancy term for the car's unique lightweight battery.  When the non-functioning prototype was shown off last year, engineers estimated its potential range at 500 km (311 miles) per charge.  It was designed to run with four 150 kW motors producing up to 715 Nm (527 lb-ft) of torque.  0-100 km/h was estimated at 5.2 seconds en route to a 275 km/h (171 mph) top speed.

The four-seat Quant has two long gullwing doors that provide access to the front and rear.  It features aggressive styling with bulging wheel arches, a cabin surrounded almost entirely by glass, and LEDs all over the front and back.

At 1780 kg (3924 lbs), the car's biggest problem may be its weight.  Still, the company plans to have a new prototype in testing by the end of the year, with the aim for a production-ready version in 2012.
