Although I am not a fan of AWD handling characteristics, in an EV the benefits of having regen on the front axle cannot be overstated. 70% of braking force is generated by the front axle and in a RWD EV this is essentially wasted, or in most cases, the rear regen is turned up so much as to cause stability issues in limited grip situations.
It always frustrated me watching F1 (In which all cars have been hybrids for a few years now) when a team was struggling with front brake issues, normally due to heat and overuse. I know the technology isnt there yet, but in the future if they could fit a hub motor on each front wheel they could regenerate so much energy in each braking zone while forgoing brake overheating issues
