Although photos of the Audi e-tron concept leaked onto the internet days before its official debut at the 2009 Frankfurt Auto Show, Audi has managed to keep a tight lid on its technical details.
From a design standpoint, the e-tron looks like an R8 that has gone backwards through the concept-to-production process, receiving futuristic-looking headlights, taillights, and wheels on the outside and a spartan, futuristic cockpit featuring an LCD display in the middle of the gauge-cluster inside.
It's not known exactly what kind of powertrain is inside. The absence of air intakes and exhaust pipes point toward it being a full electric (as does the name), though there are rumors that it's a hybrid similar to the BMW Vision EfficientDynamics Concept.
