GENEVA MOTOR SHOW: Quant F - the 300km/h electric shock

Electric car maker nanoFlowcell will once again unveil a pioneering electric car concept.

Following on from the Quant e-Sportlimousine concept from last year’s Geneva motor show, nanoFlowcell's new Quant F is just as wild but offers more power, a greater range and a new two-speed transmission.

Producing an incredible 800kW the new Quant F has 120kW more than the e-Sportlimousine it’s based on but can also travel 800km between charges - 200km more than last year’s concept.

Apart from its top speed, nanoFlowcell hasn’t released performance figures for the Quant F yet although it claimed last year’s concept could sprint from zero to 100km/h in just 2.8 seconds - so it's a safe bet the more powerful Quant F will be faster still.

In normal conditions the Quant F runs in all-wheel drive but the front axle can be decoupled for greater range.

Engineers have also made the electric car lighter with a bodyshell now made entirely of carbonfibre. The new Quant F gains a new two-stage aerodynamics to cope with the greater performance and higher top speed.

Under the skin the same salt water "nano flow cell" technology carries over but it’s now thirty per cent more efficient offering an energy density at least five times greater than a conventional battery cell.

The salt water is, of course, really an electrolytic fluid made up of metallic salts rather than plain seawater but, according to the developers, the added range it brings could provide the much-needed breakthrough for electric vehicles and make the range anxiety a thing of the past.

Pricing is expected to be announced on its launch at the show but it won’t be cheap. A production version of the last year’s e-Limousine concept was reported to cost a cool $1.7m.
