Tesla's Last Model S/X Units Ever Hit the Production Line

Tesla is officially closing the book on the two vehicles that started it all. The very last Model S and Model X units the company will ever make are now rolling off the production line at the Fremont factory in California. To mark this historic end of an era, Tesla has scheduled an official delivery event for next week on Tuesday, May 12, 2026.

The Final Production Run

This ultra-limited "Signature Edition" run consists of only 350 vehicles — 250 Model S units and 100 Model X units. These weren't available to the general public; instead, Tesla sent out exclusive invites to select long-time customers last month. Recent aerial images from the Fremont factory show some of these final units gathered in the outbound lot, ready for their new homes.

"Signature Model S / X Production BEGINS! Congrats to all who ordered!" shared @DennisCW_ on X, posting aerial footage that captured the final flagship duo being prepped. Every one of these final units is a top-tier Plaid variant and includes the exclusive Luxe Package. Owning a piece of history isn't cheap, though; both the Model S and Model X Signature Editions are priced at $159,420. This is a significant jump over even the recently hiked inventory prices of $124,990 and $129,990 for standard Plaid models.

Making Room for the Future

Tesla isn't just stopping production because it wants to; it needs the space for its next big evolution. Once these last 350 cars leave the building, the floor space previously dedicated to the Model S and Model X will be repurposed for manufacturing Optimus, Tesla’s humanoid robot. This transition highlights Tesla's shift from being a traditional automaker to a massive AI and robotics powerhouse.

For those lucky enough to secure an order, the Model S and Model X Signature Edition feature a bespoke "Garnet Red" paint, gold piping on a white interior with Alcantara accents, gold Tesla "T" badges, a numbered dashboard plate (e.g., 1/250), Signature Edition puddle lights, and more unique touches. That said, there are some unique strings attached. Tesla is requiring all Signature Edition buyers to sign a one-year no-resale agreement. Additionally, the company is retaining the "right of first refusal," meaning if an owner wants to sell the car after that first year, they must offer it back to Tesla first.

The End of an Era

The Model X has already essentially sold out in Tesla’s U.S. inventory, leaving only a few demo units behind. In fact, the Model X was recently named the fastest-selling used vehicle in the country as buyers scramble to grab the last few falcon-door SUVs.

Tuesday’s event will be a celebration of the legacy these two cars built. They proved that electric vehicles could be fast, luxurious, and technologically superior to gas cars. While it’s sad to see the flagships go, the transition to Optimus shows that Tesla is already looking at the next decade of innovation.
