Audi e-Tron renderings - Click above for high-res image gallery

Apparently, electric cars aren't such a bad idea after all. Just days after Audi of America President Johan de Nysschen proclaimed that diesels were the future in lieu of electrons, Audi's own electric supercar concept will be officially debuted at the Frankfurt Motor Show. While we're anxiously awaiting Audi's scheduled press conference, a slew of renderings managed to make their way to the internet this morning that show some of the car's interesting visual details.

Called the e-Tron, Audi's eco-friendly supercar concept is based heavily on the underpinnings of the German automaker's awesome R8. Major differences include a closed-off front grille, revised front and rear fascias with C-shaped LED head lamps and a unique set of multispoke wheels. Perhaps the most obvious change is the deletion of the standard R8's trademark side blades. We sorta miss 'em, though it's understandable that aerodynamics are the name of the game for this concept car.

We're still not sure what exactly will power the e-Tron, but the smart money is on a fully electric drivetrain. Check out our gallery of official-looking renderings below.
