Hybrid would be interesting & 4 wheel drive would likely go well with that concept. Remember there’s a guy who already converted his S550 to 4WD so it’s feasible. Weight would be the concern with doing all that, Mustangs are heavy compared to other performance hybrids.
I wouldn’t put it pass them to tell a white lie like that and then drop a hybrid. It’s the new way to sell EV without being fully EV but meets 2030 emissions goals.
