Powering those electric motors will be an array of lithium-ion batteries that provide an energy content of about 42 kWh, which should provide a driving range of around 150 miles. Of course, driving on a race track in the manner above will drastically reduce this. Also, as demonstrated above, the car is eerily silent at low speeds but once the pace picks up wind and tire noise make it just as loud as any other car. Audi plans to install an artificial sound generator to circumvent the low speed silence issue.

While outright speed won’t be a priority with the R8 e-tron, lightweight construction certainly will be as this is one of the key preconditions for efficiency and range in electric cars. Audi engineers are therefore drawing on one of the automaker’s core competences for the R8 e-tron, its aluminum Audi Space Frame (ASF) construction. The car is expected to tip the scales at around 3,500 pounds, which may seem heavy but is actually reasonable for an electric car, especially one with this level of performance.
