Musk’s tweet said, “Starting on Monday, Tesla will no longer be taking orders for the 75 kWh version of the Model S & X. If you’d like that version, please order by Sunday night at Tesla.com,” with Monday referring to January 13, 2019. This is a big deal because the next-cheapest versions of the Model S and X are far more expensive than the 75 kWh models. The Model S 100D with dual-motors and a 100 kWh battery costs $94,000, $18,000 more than the 75D. The Model X is even pricer at $97,000, $15,000 more than the 75D.
