Elon Musk, talking about Tesla’s super charger network in 2013:
They will be free forever.
For Teslas ordered after January 1, 2017, 400 kWh of free Supercharging credits (roughly 1,000 miles) will be included annually so that all owners can continue to enjoy free Supercharging during travel. Beyond that, there will be a small fee to Supercharge which will be charged incrementally and cost less than the price of filling up a comparable gas car. All cars will continue to come standard with the onboard hardware required for Supercharging.
Translation: We found a loophole: We never promised “free unlimited charging!”
These changes will not impact current owners or any new Teslas ordered before January 1, 2017, as long as delivery is taken before April 1, 2017.
Translation: Screw you, future Model E owners.
