EV Range: 16 miles; MPG-e: 83; MPG-gas: 36. Base Price: $40,475. The Audi A3 Sportback e-tron is the plug-in hybrid hatchback version of the automaker’s entertaining subcompact sedan. With a paltry EV-only range that saves an owner just $250 a year in fuel costs, and a sticker price that’s $7,550 higher than a gas-only A3, breaking even is a long-distance run here, even with a one-time $4,502 federal tax credit.
