We make radically different hydrogen electric cars. Circular business model that prioritises long-lasting vehicles built with advanced, lightweight materials. MaaS. 🇬🇧 Testing underway in the UK now, scaling up with regional manufacturing plants next.
🇩🇪Last week, the Federal and Bavarian governments announced a letter of intent for €273 million for the BMW HyPowerDrive project, with fuel cell cars to come onto the market in 2028 👇

Cardiff is the first UK council to charge more for parking big cars. ☝️London, it’s your turn…
🚙💨 Heavy cars like SUVs = more pedestrian fatalities, less space for others, higher resource consumption, higher energy consumption on the road and more NEEs – whatever powertrain is used.

Our vehicles are still providing the most impressive data on our hydrogen fuel cell powertrains; so we’re celebrating H2 this morning, with some routine testing after our meeting.

Big vehicles have a heavy cost. For every life saved by being in an SUV or pickup truck, 4.3 other lives are lost; for the heaviest 1% of SUVs or trucks, this ratio soars to 12:1.
We’re opting out of the pointless race towards ever vehicle size and power.

The Rasa weighs in at around 660kg. This means low particulate emissions, as well as zero from the tailpipe. 🪻
