Riversimple unveiled their working prototype, the Rasa (from Tabula Rasa, which means cleans 'clean slate' in Latin) on 17 February 2016 after 15 years in production. (Their first version was known as the Riversimple Urban Car). The Rasa has been designed by renowned car designer Chris Reitz, who styled the new Fiat 500. The Rasa has a range of 300 miles on 1.5kg of hydrogen, and achieves the equivalent of 250mpg with a top speed of 60mph. Emissions are zero at tailpipe (just water vapour) and c.40gCO2/km Well-to-Wheel. Hydrogen refuelling for the Rasa takes three minutes.
The Rasa is an open source vehicle. Riversimple cite the reason for this as wanting to work towards common goal of reducing environmental damage.
