The Audi E-Tron EV will receive a hotter variant soon, and the spy shot above catches it testing. A revised powertrain would allegedly pack a three-motor layout, rather than the standard model's two motors. This setup would boost the output to an estimated 500 horsepower (373 kilowatts) or 550 hp (410 kW). A higher-capacity battery would help mitigate the more powerful setup's extra muscle. Look for it to debut in 2020.
