You won't have a tough time remembering the name of Audi's first electric vehicle, not when the automaker says the SUV will simply be called the E-Tron. That's it -- no model designation, no numbers, nothing else. The automaker told Autocar that it's using the tactic it used back in the '80s when it named its all-wheel drive the Quattro. "It is comparable to the first Audi Quattro, which was known simply as the Quattro," Audi chief Rupert Stadler told the publication. "In the long term the name E-Tron will stand for a pure electric driveline structure."
