How much do Tesla Model S owners like driving for free? A lot, apparently. Since unveiling the Tesla-only fast charging system almost exactly a year ago, over three million miles have been put on Tesla EVs thanks to Supercharging. Tesla announced today that, "More than 3.2 million miles have been charged at Tesla Superchargers, offsetting about 130,500 gallons of gas." At today's average gas price of $3.472 a gallon, that's $453,096. Or, as David Sohl said on Twitter, that's roughly the equivalent of Tesla Motors giving away five free cars.
Tesla CEO Elon Musk has promised that the sometimes-solar-powered Superchargers will be free forever. To get more people to know about this growing network, Musk will be adding a few thousand miles to that overall total when he makes a crosscountry road trip with his five kids in a Model S later this year. The route is mapped out and the charging stops are planned, so keep an eye out for the Musk brood at a Supercharging station near you.
