The High Aldwin
Back in the 1980s (if this is the right OHTHMU) only 800 pounds, but 30 mph is pretty darn good. Google says around 1200 lbs now. But they often don't specify what they mean by lift.
Well, 1200 lbs. also not specifying what "lift" is (but given moves in comics, I would guess overhead) is feasible for Powerful Build with STR 20 in D&D already, at 1st level.
So, some races already have it, and allowing Powerful Build via a feat or class feature would be possible.
Is that enough for the people who want martials to rival casters? Probably not.
