True, and let's be honest, by tripling the fuel consumption, we'll get immense problems with getting fuel, especially when you've only got, say, a Fennek's volume to work with and need a good operational range while carrying five guys in power armor.

A Fennek has an operational range of... 860km/530 miles and it's roughly 10.4 metric tons (or 11.5 US tons). In comparison, my current humvee-type vehicle has a 10-hour operational time, can move at 64.4km/h off-road, and weighs in at just a smidge over 24 metric tons.

It makes the rules rather hostile to ICE in general.
