It’s not often that we spend quality time with automobiles here at Engadget, but our motives are usually geared by electricity when we do. Take for instance, the Audi A3 e-tron concept above. This isn’t the first e-tron concept — if you’ll recall, the A1 and A2 EVs were recently cancelled — but back in November we learned that the German automaker planned to begin testing this all-electric plug-in in four regions within the US. It hopes to gain insight into how these cars will take to different climates and roadways in the country, while finding out how it will fit into drivers’ daily lives. Naturally, the goal is to have something ready for consumers, but Audi figures that it’s still about two years away from realization.
