The company did not say if it was an expiration date for the free offer of Supercharging, although Electrek obtained a note that did not treat it as a limited time campaign.
It is a remarkable change of heart, but not entirely unexpected. When Tesla ended the incentive, Elon Musk argued that it was "not really sustainable" with large-scale production. However, it is also clear that the sales of Model S and Model X are soft compared to Model 3. This can increase sales by making it cheaper to own one of these premium cars in regions with supercharges. On top of this, Tesla has recently raised base prices for both vehicles. While they are also more expensive to earn, the higher costs can make it easier to offer free Supercharging without a hit on the bottom line.
