The “S3XY” Era is Dead: Why Tesla Just Killed the Model S and X

The Fremont factory is pivoting from luxury sedans to 1 million Optimus robots. Here is what you need to know.

It is officially the end of the line for the cars that started the revolution.

During the Q4 2025 earnings call this week, Tesla confirmed what many analysts had feared but few wanted to believe: the Tesla Model S and Tesla Model X have been discontinued. Elon Musk referred to the decision as an “honorable discharge” for the vehicles, but the reality is much starker. The Fremont factory isn’t just pausing production; it is being gutted to make room for the Tesla Optimus robot.

The “Physical AI” Pivot For over a decade, the Tesla Model S was the benchmark for electric performance, and the Tesla Model X was the technological showpiece. But in 2025, nostalgia doesn’t pay the bills. With margins compressed by the EV price wars and these flagship Tesla models accounting for less than 3% of global deliveries, the writing was on the wall.

Musk’s strategy is now entirely focused on “Physical AI.” By removing the low-volume, high-complexity Model S and Model X lines, Tesla plans to install high-density actuator assembly stations. The goal? To produce 1 million Tesla Optimus units annually by 2027.

Why This Matters for Owners If you own a Model S or Model X, you aren’t being abandoned — Tesla has promised legacy support “for as long as people have them.” However, the used market is about to get interesting. With order books closing in Q2 2026, existing models are transitioning from “used cars” to “collector items” almost overnight.

The Bottom Line This is a classic Musk gamble. He is trading established automotive revenue for a robotic future that hasn’t fully materialized yet. The Tesla Model X Elon strategy has shifted from transport to labor replacement.
