Audi has teased an upcoming racing concept, complete with an aggressive aerodynamics package and pure-electric power.
Graphics on the aero-style wheels reveal the car will draw on e-tron electric power, while the 'quattro' graphics indicate it will be all-wheel drive.
As you can probably see, the racer will feature a huge, angular rear wing and massive diffuser at the back, along with an ankle-breaking splitter at the front. There's a hint of the R8 supercar in the side profile, although the Vision is definitely its own beast.
Beyond the electrified R8, Audi Sport has promised battery-boosted vehicles from 2020 onwards.
