The Audi E-Tron Sportback follows the course of the more-traditional E-Tron, making it debuts at the L.A. Auto Show. We expect the same setup as the current Audi EV; up to 402 bhp and 490 pound-feet of torque. But this version will bear sportier fastback styling, and possibly even an "S" badge. It could be more powerful than the normal E-Tron.
