Due to high demand at the end of the year, we’ve extended the order date by two weeks for customers who were unable to finalize their purchase by December 31, 2016. Any Tesla ordered by January 15, 2017 and built by April 15, 2017 will continue to benefit from free unlimited Supercharging. For Model S and Model X vehicles ordered after January 15, 2017, 400 kWh of free Supercharging credits (roughly 1,000 miles) will be included annually so that owners can continue to enjoy free Supercharging during travel.
