Audi of America President Johan de Nysschen recently told Automotive News that a version of the stunning e-tron electric supercar it presented last month in Frankfurt is heading to production. The anticipated arrival will likely be sometime within the next two years, although another Audi source told Kelley Blue Book that the timing of its U.S. introduction is still under discussion and that the car could go on sale in other world markets before we see it here. Nysschen offered no other details about how a production version of the e-tron might differ from the showcar, which wraps its aluminum space frame in composite body panels and uses a Lithium-ion battery pack to energize four individual motors that turn out 313 horsepower and a pavement-warping 3,319 pound-feet of total torque. Our Audi source also indicated that the automaker is currently exploring the possibility of introducing several other less exotic hybrid and zero-emissions vehicles during that same 2012-1013 time window. Beyond a Q5 hybrid already due sometime in 2011, one likely contingency with broader market appeal could be a new, pure-electric version of the firm's diminutive A2, currently a Euro-only model that slots in below the A3.
