European officials have given nanoFlowcell AG – a drive technology R&D company from Lichtenstein – the go-ahead to test their QUANT e-Sportlimousine electric supercar on public roads.

This may not seem such a big deal, with new prototypes hitting the streets every other day, but what marks this project out is the revolutionary drivetrain. At the all-wheel drive concept’s heart is a flow cell chemical battery that uses liquid electrolytes (which could just mean sea water) to produce electricity.

Apparently capable of powering the 2,300kg Quant e-Sportlimousine 373 miles, this high energy density nanoFlowcell system feeds four three-phase induction motors, one for each wheel, and can generate as much as 912bhp.

0-62mph is claimed at 2.8 seconds, with a top speed of over 235mph, with all of this performance available alongside consumption of just 20kWh/100km – the equivalent of 125mpg.

“Now that the automobile has been approved for use on public roads in Germany and Europe we can enter into detailed planning with our partners, adding an exciting new chapter to the future of electro-mobility,” said chief technical officer Nunzio La Vecchia, emphasising the importance of this latest step in the company’s plans for series production.

Revealed publically at the Geneva Motor Show in March, the four-seat Quant e-Sportlimousine is certainly going to be hard to miss if it makes production. Measuring in at 5.25 metres long, 2.2 metres wide, the 1.35metre high concept sits on 22-inch wheels and features double gull-wing doors.

Finished in distinctive ‘Chrystal Lake Blue’ paint, the floating roofline conceals a futuristic cabin, complete with full-length interactive dash, wood-theme detailing and Android-based infotainment system.
