Shortly after the official unveiling of the E-tron supercar at the 2009 Frankfurt Motor Show, Audi announced that it would be put into production in a limited 1000 units. The first prototypes that were caught testing is proof to that statement. The E-tron will compete with the electric version of the Mercedes SLS AMG->ke2504 which Mercedes is currently working on.

The prototype caught testing has no air intakes and the traditional front and side air intakes of the V8 and V10 R8s->ke1440 have also been removed.

The E-tron concept is powered by a purely electric drive system made up of four motors – two at the front and two more at the rear axle. The total output of this electric drive system is 313 HP and 3,319.03 lb-ft of torque, meaning that the car can sprint from 0 to 60 MPH in just 4.8 seconds and from 60 to 120 km/h (37.28 – 74.56 mph) in 4.1 seconds.

If anyone is interested, as we assume some people might be, then you better start putting away some dough. Audi has said that the E-Tron should be in showrooms by the end of 2012 and will be more expensive than the Audi R8 which starts at about $114,200.
