Hugo Spowers didn’t just want to reinvent the car, he wanted to reshape car ownership as well. Even Tesla’s Elon Musk himself would goggle at the scale of the work Spowers’ company Riversimple has given itself.
The proposed car is a two-seat, carbon-fibre fuel-cell coupe that’s been uppermost in this former race-team owner’s life since he first set up the company in 2001. Since then the project, now based in Llandrindnod Wells, central Wales, has sucked in £20 million of investment funds and seen the projected production start date pushed back multiple times.
The Rasa’s fuel-cell powertrain with the additional acceleration boosting ‘supercapacitor’ batteries (which release power very quickly) and in-wheel electric motors is radical enough but Spowers doesn’t dwell on this, calling it ‘off-the-shelf’ technology.
Instead, Riversimple's breakthrough is said to be at a ‘system’ level. Spowers draws a comparison with how Cooper humbled Ferrari in Formula 1 in the 1950s by focusing attention away from the engine by completely reinventing the layout. So Riversimple fits a tiny 10kw (13bhp) fuel-cell stack from Cummins and relies on a max 70kW (94bhp) from the supercapacitors to beef up acceleration so the car can hit 60mph from rest in around 10 seconds.

The carbon fibre chassis weighs just 72kg for a combined car weight of a projected 580kg, so there’s not much to push along. Even so, top speed is currently capped at 60mph, at least at the moment.
The range with just 1.5kg of hydrogen on board is said to stretch to 300 miles but the Rasa isn’t a car intended to cure battery-induced long-range anxiety. Instead this is a ‘local’ car that’ll be sold to customers in specific geographic areas that are within range of a hydrogen pump that they’ll top up from weekly. Encouraging fuel retailers to install those hydrogen pumps and solve the UK’s almost non-existent refuelling infrastructure is another item on Spowers’ insane to-do-list.
Riversimple cares deeply about how little hydrogen you use because it’s paying. Customers subscribe to cars at £354 a month plus 21p a mile. That includes everything: insurance, maintenance, fuel, tyres, the lot. “Don’t say it looks expensive until you’ve totted up all your bills, not just compared it to the PCP figure,” Spowers says. Also, zero emission cars, whether battery or fuel cell, are expensive.
“The cost price of a combustion engine car is truly incredibly low,” he adds. Spowers says his company’s newest date for production is 2024 in a new factory scheduled to be built at one of two possible sites in Wales, a push back from this year predicted when we last spoke to him in 2019. Entrepreneurs with lesser spirit might have thrown in the towel by now but not Spowers. “The thing that is slowing us down is always funds,” he admits. “We’re working way ahead of the curve so we have been pushing against closed doors.” The difference now he says is the growing interest in zero carbon transportation. “Those doors are now opening.”

A lifestyle company existing purely for the benefit of the directors.
If this was a viable model then BMW, Mercedes, Toyota or one of dozens of other companies could knock this together in six months and sell them for £30k each or less.
Except they couldn't because they couldn't and wouldn't make a car the doesn't bother with minor irritants like modern safety features.
The beginnings of Riversimple go back over 20 years, and at that time may have had a certain logic behind them. Mind, it's not so much later that Musk and Tesla wre just starting out, and Musk (who could have as easily gone hydrogen as battery with Tesla at the start) famously made his "fool cells" comment. Roll on and Musk is the richest individual on the planet, and Hugo Spowers......... is dependent on grants. Ask yourself which most likely made the right decision.
And frankly, much of what Mr Spowers says doesn't really hang together. He conveniently ignores inconvenient truths such as fundamental issues with hydrogen filling stations. Where does the hydrogen come from? At the moment, mostly from natural gas - so emitting CO2 at the refinery rather than the tailpipe. Hardly green. And it's far harder to distribute than petrol or diesel due to the weight of the pressure vessel on the tanker. Like for like, you'd need about 10-15x as many tanker deliveries for this reason with hydrogen.
Possibly the hydrogen could be made on site via electrolysis. But Mr Spowers criticises electric on grounds of how such as motorway servive stations would need large electrical powers. What he glosses over is that hydrogen via electrolysis would need about 3x as much electrical power like for like, due to inefficiencies in electrolysis, compression and fuel cells. And he also glosses over that with battery electric most recharging will likely happen at home, spreading the load.
And this before we even start thinking about the car itself. Is the business model Mr Spowers enthuses about really so different to standard leases? Maybe it's worth asking why Riversimple haven't simply seen the light and switched design to battery? Good question. My own suspicion is that they realise that direct comparisons would show they just weren't competitive with all the small urban battery cars coming out from the established manufacturers (eg the 500e), and sticking with hydrogen acts as a differentiator. It's not going to go anywhere - but it's a good angle when applying for grants to organisations who may have a fear of missing out on a possible (?) new thing - especially when they may not be totally aware of the technicalities. And add to that not wanting to be the one seen as responsible for losing jobs in such an area of Wales.......

The Rasa is the opposite to Dr Who's Tardis - small on the inside, big on the outside. Exactly what is not needed for a small urban car. Performance is risible, but what is not mentioned is that the supercapacitors will only enable it to maintain any sort of speed on a hill if the total height is less than about 500ft. Any more and it must revert to pure fuel cell output and will crawl.
It's been about 2-3 years away for a decade or more now, and the company is only kept afloat by grant after grant. Total waste of taxpayers money. Just let it die.
