Lightness is key to efficiency and range. We have used a combination of technologies to keep the weight to a minimum and deliver the greatest fuel efficiency and superb environmental performance. Like a Formula One car, it is built with strong and lightweight composite materials rather than steel. Our production vehicles will be designed to deliver a range of 300 miles, which would last most people a week of local travelling before needing to refuel.
Riversimple began with a hydrogen fuel cell, a manifesto for sustainable design and a blank sheet of paper. Every aspect of our technology is continuously interrogated for simplicity, efficiency, lightness, strength, affordability, safety and sustainability. And the name of our first model, the Rasa is a nod to that blank sheet of paper – Tabula Rasa means ‘Clean slate’ in Latin.
The Rasa is an electric car powered by hydrogen rather than batteries and emits water. The hydrogen passes through a fuel cell, where it combines with oxygen from the air to produce electricity. This electricity flows to small, lightweight electric motors, one in each wheel, which give the car 4 wheel drive.
