There is only 1 production electric UTV in development, Nikola NZT which will be prohibitively expensive once available

One thing I really have to give Nikola Motor credit for: they do great marketing! In this case, they've convinced at least one person that all of their competitors don't exist - a neat trick.

Just do a web search for "electric UTV", and pick your brand. Polaris and Textron (the old Arctic Cat) are the most obvious choices as experienced UTV manufacturers, but there is at least one entry from China as well.

Since this thread has been revived, a more direct answer to some of the original post...

Water, mud, dust, dirt, and sand would be issues for components which are not sealed... especially typical brushed DC motors. Sealed (and liquid-cooled) AC motors are readily available and should not have any difficulty with these factors.

Rocks and brush/trees don't have much to do with the powertrain. Even ice and snow are only relevant to traction, which isn't a problem for the EV components.

Vibration could be an issue for electronics, but I wouldn't expect an issue with automotive-grade components. Anyone home-building a controller should be careful with connections and component mounting on boards.

Snow can be quite a good insulator when it cakes up on heatsinks and radiators.

Good point, although no different from a UTV with an engine.
