Riversimple Rasa is pretty small
The Rasa is a new hydrogen fuel cell car, unveiled by the Riversimple Movement, headquartered in Llandrindod Wells in Wales, and developed thanks to £2m grant from the Welsh government in 2015.
It's pretty small, ultra-light two-seater, which weights only 580 kg (1,279 lbs). Weight (lowered by use carbon composite chassis), size and aerodynamic makes is also fuel-efficient as just 1.5 kg of hydrogen in needed for 300 miles according to press release.
"...every aspect of the Rasa has been tailor-made and interrogated for lightness, strength, affordability and safety, to produce a vehicle that will maximise hydrogen as a fuel source and minimise pollution."
Later this year Riversimple intends to launch public Beta with 20 cars, while sales could launch in 2018 in “sale of service” model (fixed monthly fee and mileage allowance).
Interesting is also intention to "adopt an open-source approach to its technology and componentry to encourage the proliferation of its technology and economies of scale within the sector"
"Riversimple will offer the car to motorists through its unique “sale of service” model. For a fixed monthly fee and mileage allowance, similar in expenditure to leasing and running a new family-sized hatchback, the company will cover all repair, maintenance, insurance and fuel expenses. Customers will never actually buy the car and experience the burden of depreciation; they will simply exchange or return it at the end of the ownership period."
More about the Rasa:
"When the vehicle is in motion, hydrogen passes through the small 8.5kW fuel cell (the size currently used in forklift trucks, equivalent to 11hp), where it combines with oxygen to form water and electricity to drive the motors positioned in each of the four wheels. More than 50% of the kinetic energy produced under braking is recovered and turned into electricity to boost acceleration via a bank of super-capacitors. The result is a range of up to 300 miles on 1.5kg of hydrogen, estimated fuel economy equivalent to 250mpg, and a top speed of 60mph. At around 40g CO2/km, the Riversimple car has the lowest carbon emissions for any vehicle 'well-to-wheel', and water is the only output.
Starting later this year, following funding to match a €2m EU grant, Riversimple will be conducting a public 12-month Beta trial of 20 Rasa prototype cars as part of the continued development of the first full production model which will come to market in 2018. It will be offered to individuals in a strategically planned phased roll-out by region in order to support a low risk, commercially practical introduction of profitable hydrogen refuelling infrastructure."
Hugo Spowers, Founder of Riversimple Movement Ltd, said:
“The Rasa engineering prototype marks another key milestone in bringing an affordable and highly-efficient hydrogen-powered car to market. We really have started from a clean sheet of paper. The Rasa gives us the opportunity to introduce customers to a more convenient concept of motoring, a lightness of ownership that neither places a burden on the pockets of motorists or the surrounding environment. The car is simple, light and fun in every respect.”
