Look, as cool as it could be and as much as automakers want it to happen, a worldwide switch to hydrogen passenger vehicles is just not realistic or even possible. But as the technology improves, hydrogen fuel cells become more appealing and possible for use in commercial applications, like long-haul semi trucking and delivery vehicles. Mercedes-Benz has previously shown a prototype hydrogen fuel-cell semi that did 621 miles on one tank, and now the brand has revealed a prototype Unimog that uses hydrogen to power an inline-6 combustion engine.

If you aren’t already aware of its gloriousness, the Unimog is Mercedes’ giant off-road rig that has been in production since 1951, forming the basis for everything from fire trucks and construction vehicles to go-anywhere RVs and passenger trucks.

The hydrogen combustion engine is part of the publicly funded “WaVe” program, where 18 different partner companies and agencies are working together to determine whether these engines can supplant diesel-powered engines. Despite this development, Mercedes says it is focused on battery electric and hydrogen fuel cells for production and commercial uses. I’d love to see what a next-gen Unimog EV would look like.
