Unveiled at this year's Geneva Motor Show is the e-Sportslimousine from Liechtenstein-based energy company nanoFLOWCELL AG, featuring an advanced battery pack to power the electric drivetrain contained within a strikingly sleek silhouette. The company claims its NanoFlowCell technology has five times greater performance-by-weight than the current lithium-ion technologies in most of today's electric vehicles. Additionally, the driving range is said to be five times greater than a conventional unit of the same weight. The "flow battery" technology uses tanks of negatively and positively charged electrolyte solutions, pumped into a central cell stack that drives four electric motors, one for each wheel. The resulting combined power output is rated at 912bhp, enabling a 0-62mph sprint in 2.8 seconds, and a top speed in excess of 236 mph. Check out a video overview below.
