2035 ICE Ban
Undrivable overnight
Classic cars risk becoming undrivable across Europe when internal-combustion restrictions tighten.
A specialist workshop engineering hydrogen internal-combustion retrofits for iconic European classics — so the cars we love keep driving, without the emissions.
Three problems collide — and no one has solved all three.
Classic cars risk becoming undrivable across Europe when internal-combustion restrictions tighten.
+250–400 kg of batteries wreck the dynamics, the weight distribution and the character that make a classic a classic.
Only a handful of public hydrogen stations exist in Iberia today — the infrastructure story needs to be proven.
Hydrogen internal-combustion conversion — OEM weight, zero tailpipe CO₂, real touring range. The engine still breathes. The soul is retained.
500–700 km range, 3 min refuel — but ~220 g/km tailpipe CO₂ and facing regulatory sunset.
Zero emissions — but +250–400 kg added mass, 45+ min charging and a car that no longer feels like itself.
Zero tailpipe CO₂, ±5% of OEM weight, 450–600 km range, 4-minute refuel. Character preserved.
| Original ICE | BEV Conversion | H2 Classics | |
|---|---|---|---|
| Tailpipe CO₂ | 220 g/km | 0 | 0 |
| Added mass | baseline | +250–400 kg | ±5% of OEM |
| Character preserved | Yes | No | Yes |
| Range | 500–700 km | 200–300 km | 450–600 km |
| Refuel time | 3 min | 45+ min | 4 min |
We retain the soul.
A focused platform envelope means a repeatable conversion. We engineer once — for the icons of the era.
H2 Classics converts the engine to burn green hydrogen directly — keeping the mechanical soundtrack, the throttle response and the touring manners that made these cars legends. The only thing leaving the exhaust is water vapour.
Preserving heritage. Proving hydrogen.
Every retrofit we build is validated on real European roads. H2 Rally is the pan-European drive proving what these cars can do — starting from Lisbon in June 2027.
