This just in my inbox... An Update to our Supercharger Program Four years ago, Tesla introduced the Supercharger Network – the world’s fastest charging solution – to enable convenient long distance travel. Today, more than 4,600 Superchargers allow over 160,000 Tesla owners to drive all over the world. We recently announced a change to the economics of Supercharging – one that allows us to reinvest in the network, accelerate its growth and bring all owners, current and future, the best Supercharging experience. Any Tesla ordered by December 31, 2016 will continue to benefit from free unlimited Supercharging. For Model S and Model X vehicles ordered after January 1, 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.
