The versions of Tesla's Model S and X electric vehicles with mid-range 75-kilowatt-hour battery packs are about to be discontinued, meaning the cheapest versions of those vehicles will have base prices of just below$100,000.

The company's CEO Elon Musk made the anouncement via Twiiter on Wednesday. He said that beginning next week customers won't be able to order 75D Model S sedans and X crossovers. Those versions are priced from $76,000 and $82,000, respectively, excluding accessories, taxes and federal and state incentives. Here is the tweet:

“Starting on Monday, Tesla will no longer be taking orders for the 75 kWh version of the Model S & X," Musk said. "If you’d like that version, please order by Sunday night at Tesla.com.”

The next cheapest Model S, the 100D, starts at $94,000, and the 100D Model X is priced from $96,000, according to the company's website. They come with 100-kilowatt-hour packs.

Tesla has been the biggest beneficiary of a $7,500 federal tax credit that helped make its pricey vehicles a bit more affordable, but Tesla hit a numerical ceiling on that incentive in 2018. All Teslas purchased in the U.S. since 2019 began now receive only a $3,750 tax credit for now.

In March 2017, Tesla had also eliminated the 60 kWh Model S, the cheapest version of which started at $68,000.
