car 770

Riversimple pulled the sheet off its ultra-lightweight fuel cell Urban Car today in London and said it delivers a 50-mph top speed, a 200-mile range and fuel economy equivalent to 300 mpg. The company claims it also emits a paltry 30 grams per kilometer of CO2. The car features a 6-kilowatt fuel cell, which is miniscule compared to the 100-kW unit in the Honda FCX Clarity, but the developers say that’s plenty for a vehicle that weighs just 770 pounds.
