NanoFlowcell

Nanoflowcell is showing the latest version of the Quant flow battery sports car. Unlike the Quants of the past, the new 750-hp Quant 48Volt sees its voltage drop precipitously, from 700 V on last year's Quant FE to the namesake 48 V. Performance doesn't drop at all; in fact, it only gets better.

Nanoflowcell's flow cell-powered Quant and Quantino cars are nearly ready for production. It'll show the latest versions at this year's Geneva Motor Show.

Building upon the groundwork it laid at last year's Geneva Motor Show, Liechtenstein's Nanoflowcell used this year's show to highlight two very different ways that its flow battery technology can be put to use: the Quant F hypercar and the Quantino commuter.

Before it detailed the 1,075-hp Quant F supercar, Nanoflowcell mentioned that it would have another surprise highlight at the Geneva Motor Show. Turns out, the surprise is an entirely new concept car that it calls the Quantino.

Nunzio La Vecchia is back, baby! And at this year's Geneva Motor Show, he's pitching an even more extraordinary, updated version of his flow cell supercar, the Nanoflowcell Quant F. La Vecchia claims that the updated car's flow battery can power the motor to a tune of 1,000 hp and 500 miles.

Throughout 2014, concept cars broke ground on the future of cleaner commuting, showcasing technologies that will get us from point A to point B without so much impact on the rest of the alphabet. Here are our favorite green concept cars from the year.

After making a debut at the 2014 Geneva Motor Show, the Quant e-Sportlimousine has received approval from Germany's TÜV Süd. The car, which uses an electrolyte flow cell power system, is now certified for use on German and European roads.
