NanoFlowcell is going to reveal its first concept version of Quant 48Volt at this year’s Geneva Motor Show. The Liechtenstein-based company is developing an engine powered by batteries that run on electrolyte liquid – otherwise known as flow batteries. They have some promise and purport to solve some of the issues of conventional batteries, but we've yet to see any proof beyond the company's estimates. Take the rest of this report with a pinch of salt, perhaps two. The numbers thrown out by NanoFlowcell are pretty impressive. The Quant 48Volt's motor will deliver 760 horsepower that will propel the all-wheel-drive car from 0 to 62 miles per hour in a tidy 2.4 seconds. And the car will have a top speed of about 180 miles per hour. The car's layout, complete with tanks for positive and negative liquid electrolytes, allows for 40 gallons of fluid and a full-tank range of more than 600 miles. More impressive on the green front is that the company estimates the liquid to cost less than a nickel per gallon. The unknowns, are the price of the car, the expected on-sale date, and whether any of these numbers will pan out.
