I can't really add anything to the discussion about power source or electric motors but in the spirit of brainstorming, it might be worth looking at the LeTourneau company (and discussions about them) for information about electric drives. They've been in the business of manufacturing large vehicles with electrically powered wheel motors since the 1960s.

Granted their tech is focussed on earth-moving and construction vehicles and the electrical generation is typically done by a diesel generator but there's a few gems of info to be found in websites that discuss the company or their products. For example, there's been mention on a few websites that the diesel electric configuration is very quiet and it's probably safe to assume that Project vehicles would have the same level of stealth (or better) but that is something that is rarely mentioned (if ever) in any Project material that I've read.
The hybrid drive that LeTourneau used is reasonably common for various heavy plant so it might be worth checking other companies as well like Komatsu and so on.
