That alone makes the efficiency favor AC.
Most AC motors are designed with a flatter torque curve
whereas DC motors tend to peak really low then fizzle.

Plus, most production AC EV motors are good to 15,000 RPM. The Advanced DC is good to about 5,500-6,000 RPM. Longer power curve means less need for a transmission.
