One of Tesla’s best known incentives is coming back as the company has announced everyone who orders a new Model S or Model X will get free Supercharging for life.

The announcement is pretty self explanatory, but the automaker said there won’t be any limits this time around. That’s a good thing as Car & Driver noted a previous offer limited free Supercharging to 400 kWh annually.

There’s no word on how long the promotion will last, but consumers should probably act fast as Tesla has been known to change pricing and incentives with little to no notice. Of course, if you can spend upwards of $70,000 on a vehicle, you’re probably not too worried about the costs of recharging it.

While Tesla didn’t say much about the move, there’s speculation that it’s an attempt to reinvigorate sales of the company’s oldest models. That remains unconfirmed, but the Model 3 is currently the company’s best-selling vehicle and the automaker is also seeing plenty of pre-orders for the upcoming Model Y.

As announced earlier this year, Tesla had a record second quarter as the company produced 87,048 vehicles and delivered 95,356 units. A large majority of them were Model 3s as Tesla delivered 77,634 units during the quarter.

The company’s entry-level model continues to be a hit as it was once again the best-selling premium vehicle in the United States and outsold all its “gas-powered equivalents combined.” More importantly, for Tesla at least, a majority of the orders were for the Model 3 Long Range which starts at $47,990 before options.

Demand for the more expensive Model S and Model X is notably weaker.  That being said, the company built over 14,500 units in the second quarter and delivered 17,722 vehicles. At the time, Tesla said they were focusing on reducing inventory and had just 18 days of stock on hand.
