The Riversimple Rasa Is A Hydrogen Concept Car That Could Save The Planet


Riversimple is the automaker most likely to save the earth. In addition to making its cars emission-free machines, it also wants to alter our entire interaction with them. People will pay to use them rather than purchase them.

While automakers are focused on producing the next generation of electric vehicles, one British company has different plans. Riversimple hopes that its hydrogen-powered two-seater car, which has a futuristic style with retro elements, would be a viable alternative to electric vehicles.


The Welsh business produced the Rasa vehicle. It can travel 300 miles on 1.5 kg of hydrogen. The engineering of the car is highly unique compared to other vehicles on the market. It features a motor, for instance, on each wheel.

This vehicle debuted at the 2016 London Motor Show. It displayed cutting-edge technology that foreshadowed an exciting future in transportation. However, it has subsequently become a forgotten concept.

Here is what the forgotten concept car has to offer.

How The Riversimple Rasa’s Hydrogen Power System Works And What It Can Achieve

The hydrogen in the fuel cell goes via a Proton Exchange Membrane, where it interacts with oxygen to generate water and electricity. The electricity is then routed to the motors located in each wheel. These motors are compact, lightweight, and provide four-wheel drive to the vehicle.

When the car stops, the kinetic energy that is commonly lost as heat gets caught as electricity. This electricity flows into a bank of supercapacitors at the front of the car as the car slows.

These supercapacitors, unlike batteries, can accept a large charge extremely quickly, but they don’t store a lot of energy. The energy they absorb is returned to the motors and used to propel them forward.

Because the electricity is networked everywhere around the car, it is known as a Network Electric vehicle. Except for returning to the fuel cell, it can flow in any direction and along any path.

Because of its unique network architecture, Riversimple only needs a fuel cell large enough to provide cruising speed power rather than acceleration.

In theory, the Riversimple Rasa has a 300-mile range while emitting just water and delivers slightly more than 260 mpg. It has a top speed of only 60 mph, but because of Riversimple’s clever construction, it reaches that pace in under 10 seconds.

The Build Of The Riversimple Rasa Is Bizarrely Amazing As It Is Practical

Riversimple created the Rasa to be straightforward, practical, lightweight, and inexpensive. Chris Reitz, who also contributed to the design of the retro-chic Fiat 500, created the highly aerodynamic two-seater.

It weighs less than 1,200 pounds thanks to a monocoque carbon fiber chassis that weighs just 88 pounds without anything attached to it and body panels made of composite materials. Because its research and development team comprises experts from the Formula 1 industry, Riversimple is familiar with weight-saving techniques.

The interior, accessed via gullwing doors, is delightfully basic and tidy. It has a three-spoke steering wheel, two seats, a pod with two instruments, a dash-mounted screen surrounded by buttons, and not much else.

Exposed carbon fiber highlights the car’s ultra-light structure. According to Riversimple, the prototype lacks a trunk, but the production model will feature approximately six cubic feet of storage.

Will The Riversimple Rasa Make Big Sales On The Market After Its Release?

Riversimple did not come out of nowhere. Hugo Spowers, the company’s chief of engineering, was the driving factor behind Morgan’s 2008 LIFECar (LIghtweight Fuel Efficient Car), a hydrogen vehicle development project.

Riversimple introduced the Hyrban, or HYdrogen uRBAN automobile, a hydrogen-powered two-seater technology demonstration in June 2009.

Riversimple is out to redefine how we drive and own our automobiles, which is much more ambitious than just producing and selling a hip little hydrogen runabout. And it won’t be simple.

Riversimple has no plans to sell Rasas to anyone. Instead, they want you to enter a lease agreement that includes the car, insurance, maintenance, and fuel, much like Toyota does with its hydrogen-powered Mirai. Consider it similar to a vehicle phone contract. Hardware, service, and utilization of supporting infrastructure are all combined.

In 2016, Riversimple announced that it would collaborate with a hydrogen supplier to establish filling stations that would serve as a focal point for all the Rasas rented in that region.

Think Coventry, Derby, and Plymouth when considering Riversimple’s first goal to target towns and cities with a population of up to 300,000. Even in towns and cities twice the desired size, this is unlikely to be a problem because filling up a Rasa takes around three minutes in lines at the one filling station.

Riversimple will introduce a last-mile delivery van based on the same powertrain, manufactured at the same plant, and employing the same infrastructure architecture as the Rasa.
