A new hydrogen fuel-cell electric vehicle prototype has been launched with a claimed fuel economy equivalent to 250 mpg (0.9 L/100km). Dubbed "Rasa," the new car has a lightweight carbon-fiber monocoque shell, in-wheel electric motors, a bank of supercapacitors charged by braking-regeneration, and a host of other features that enable it to travel up to a claimed 300 miles (483 km) on just a 3.3 lb (1.5 kg) tank of hydrogen.
A road-legal two-seater engineering prototype, the Rasa by Riversimple Movement Ltd UK has been designed from scratch to meet the company's brief of lightness, strength, affordability and safety, as well the maximization of fuel economy and minimization of pollution. Given that the pollution emitted by the Rasa is just 40 gCO2/km "well-to-wheel", even if the hydrogen is sourced from natural gas, and that water is the only substance to come out of the tailpipe, the company is claiming the lowest carbon emissions for any vehicle thus far produced.
