Audi has announced its participation in the Silvretta E-Auto Rally Montafon 2010 with an e-tron powered version of its highly-athletic Audi R8. During the 167.5 kilometer (104.08 miles) route through the Austrian state of Vorarlberg, the all-electric sports ride will be piloted by Michael Dick, Member of the Board of Management of AUDI AG for Technical Development, and the factory driver Lukas Luhr.

Michael Dick, Member of the Board of Management of AUDI AG for Technical Development, says: "We already received very good feedback on the Audi R8 e-tron in Le Mans. In Montafon, the e-tron will put its potential to the test in ten different mountain, valley and timed special stages. This is a good opportunity to showcase Audi's integrated approach and to experience the fascination of electromobility in a sports car on the road."

The technology incorporated in the R8 includes four electric motors – two on the front and two on the rear axles – which turn this test electric car into a true quattro. With its peak power of 313 horsepower (230 kW) and 4,500 Nm (3,319.03 lb-ft) of torque, the innovative race ride is capable to sprint from standstill to 100 km/h in 4.8 seconds flat, before reaching its top speed of 200 km/h. For powering the motors, Audi has equipped the transformed R8 with a water-cooled, lithium-ion battery, placed right behind the passenger cabin for an optimal center of gravity and axial load distribution.

The stunning race-ready R8 e-tron showcases Audi experts' development work, which is now far beyond the simple battery technology and the replacement of the combustion plant with an electric one. The goals of the future electromobility now highlight factors such as efficiency, range and practicality.
