Cars already were steampunk they had the cumbustion under the seats was cool but gas was stronger per design flaws It could work off many engine designs for stean punk i like a modification off the combustion engine https://en.m.wikipedia.org/wiki/History_of_steam_road_vehicles I would prefer and angular momemtum engine

Yup all power besides solar that take energy from any thermo process is steam ( there are exceptions but this is a solid premise)
