See this https://shops.audi.com/en_GB/web/zubehoer/p/retrofit-solutio... for example. I can only assume it's resistive, since it doesn't start the engine - but it might be a system for running the AC heatpump without engine, maybe. Also now that I think of it, window defrost is resistive.

I would guess system like this would be rare in US, because you are allowed to have remote start on your cars.

edit: never mind, it burns fuel https://www.auditech.org/acont-1427.html
