That's not exactly true. There is some shared wiring between the DC fast charger and the motors, but not so much that the powerful motors are "free". The wires that run between the motors and the battery are long. I think the larger third factor is regenerative braking. That uses the exact same circuitry as powering the motors, and if you want to be able to brake quickly without the brake pads, that's a lot of kW to be absorbed. Any way you cut it, I agree, it's an insane power level.
