Tesla made history with the introduction of its Model S sports sedan two-plus years ago, prompting approbation from car critics far and wide. This was the breakthrough electric car the world had seemingly been waiting for, offering attractive design, a remarkable interior, and entertaining performance. The price—starting at about $60,000 before the $7500 federal kickback—was far beyond the average household’s reach, and range anxiety will always be a concern for any pure electric, but the S was a refreshing interpretation of just how super a modern supersedan could be.
