    I didn’t think the regen could bring a car to a complete stop

    Yes, it can. Newer axial motors can actually put -700hp of stopping power per wheel, and the whole motor hub assembly weighs less than a brake assembly. All that energy was previously wasted as heat by braking.

      it is not legal in china for a car to come to a complete stop using regen braking. And most electrics come from there

      Yasa is not a current OEM. They are a research group partnered with Mercedes, not supplying Mercedes with current market equipment. So no, this is not a solution to regen braking not being able to brake the last 10% to a stop. That’s not what BMW claimed, either. They said “almost never” activate mechanical brakes. Everyone is still using mechanical brakes for the last, final stopping force. That is how generators work. If they’re not spinning they’re not generating. Slowing to a stop means the braking force from regen rides the curve down to near zero. Yada has nothing to do with the thread anyway

      700hp of stopping power per wheel isn’t regen braking, that’s dumping battery power into a stopping force.

        What do you think the (-) means? No, braking like this does not use battery power. Read the link. YASA is a Cambridge scientist with a string of papers on axial hub motors, they have a massive resistive force.

        This isn’t SAE dipshits from Detroit.
