In a move that signals the end of an era for the electric vehicle industry, Tesla has officially begun thinning out customization options for the Model S and Model X. As the closure of these two foundational programs draws near, the automaker is streamlining its inventory and production lines at the Fremont Factory to pave the way for a radical shift in its manufacturing focus. The disappearance of specific aesthetic choices marks the first tangible step toward the retirement of the vehicles that defined the modern electric car revolution.
For weeks, speculation has mounted regarding the exact timeline for the phase-out of Tesla’s flagship sedan and SUV. Now, confirmation has arrived not through a press release, but through the subtle yet significant changes in Tesla’s Online Design Studio. As of late February 2026, prospective buyers are finding their choices limited, a clear indication that the supply chain for these specific models is being wound down. The transition, while expected, brings a sense of finality to the “sentimental” favorites of the Tesla lineup.
The strategic pivot is driven by Tesla’s ambitious goals for its humanoid robot project, Optimus. With space at the historic Fremont facility at a premium, the company is reallocating resources from its low-volume, high-complexity vehicle lines to accommodate mass production of autonomous robotics. This article delves into the details of the dwindling options, the historical significance of the Model S and X, and the industrial transformation currently underway in California.
The Disappearance of Lunar Silver
The first casualty of the production wind-down is the “Lunar Silver” paint option. Previously exclusive to the Model S and Model X, this premium color is now listed as “Sold Out” in the Design Studio. Unlike temporary supply constraints of the past, this unavailability is permanent, signaling that Tesla has ceased ordering or mixing this specific pigment for the flagship lines.
The removal of Lunar Silver is not merely a cosmetic update; it represents a consolidation of the manufacturing process. In the automotive industry, as a model approaches its end-of-life (EOL) phase, manufacturers often reduce complexity to maximize efficiency and burn through remaining parts inventory. By eliminating low-volume color options, Tesla can streamline the final batches of production, ensuring that the remaining chassis are painted in colors that have higher historical take-rates or shared utility with other lines.

While Lunar Silver is gone, other options remain for the time being. Frost Blue, another distinct color, is reportedly still available, though industry analysts expect the palette to continue shrinking in the coming weeks. Tesla is likely prioritizing the depletion of existing stock, meaning that customers hoping to secure a highly customized Model S or X must act quickly before the configurator becomes even more restrictive.
Clearing the Way for Optimus
The driving force behind the cancellation of the Model S and Model X is not a lack of demand, but rather a desperate need for manufacturing real estate. The Fremont Factory, Tesla’s original production hub, is undergoing a massive metamorphosis. The facility is being retooled to support the mass production of Optimus, Tesla’s humanoid robot.
Tesla’s leadership has determined that the floor space currently occupied by the Model S and Model X assembly lines is more valuable when dedicated to the next generation of autonomous products. While the S and X are profitable, they are low-volume vehicles, contributing less than a few percent to Tesla’s total yearly delivery figures. In contrast, the company aims to produce one million Optimus units annually at Fremont once the ramp-up is complete.
This transition highlights a fundamental shift in Tesla’s identity. Moving from a pure-play automotive manufacturer to an AI and robotics company requires physical infrastructure. The complex assembly lines required for the Model X—famous for its intricate falcon-wing doors—take up significant square footage that can be optimized for the smaller, yet higher-volume, footprint of humanoid robot assembly.
An Honorable Discharge: The CEO’s Confirmation
The writing has been on the wall since the Q4 Earnings Call in January 2026, where CEO Elon Musk formally addressed the future of the flagship vehicles. In a statement that resonated with longtime supporters of the brand, Musk framed the discontinuation not as a failure, but as a graduation.
“It is time to bring the Model S and Model X programs to an end with an honorable discharge. It is time to bring the S/X programs to an end. It’s part of our overall shift to an autonomous future.” — Elon Musk, Q4 2025 Earnings Call
The phrase “honorable discharge” suggests a recognition of the pivotal role these vehicles played in the company's survival and success. The Model S, launched in 2012, proved that electric cars could be desirable, long-range, and high-performance. The Model X followed, challenging the utility vehicle segment with unprecedented technology. However, Musk’s vision for the future is predicated on autonomy—both in logistics (Optimus) and transport (Cybercab)—rendering the driver-focused luxury sedans less central to the mission.
The Legacy of the Model S and Model X
As customization options vanish, it is worth reflecting on the monumental impact of these two vehicles. When the Model S debuted, the automotive world was skeptical of electric propulsion. The vehicle shattered expectations, earning Motor Trend’s Car of the Year and achieving safety ratings previously thought impossible. It introduced the world to Over-the-Air (OTA) updates, the Supercharger network, and the concept of a “frunk.”
The Model X pushed the envelope further, introducing the panoramic windshield and the complex, yet iconic, falcon-wing doors. While the Model X faced early production hell due to its complexity—Musk once famously referred to it as the "Fabergé egg of cars"—it eventually matured into a staple for families wanting electric utility without compromise.
Technological Milestones
- The Plaid Powertrain: The introduction of the Tri-Motor Plaid configuration re-established the Model S and X as the quickest production cars in the world, proving that EVs could outperform multimillion-dollar hypercars.
- Autopilot Hardware: These platforms served as the testbed for successive generations of Autopilot and Full Self-Driving hardware, gathering the data that now powers Tesla’s AI ambitions.
- Interior Minimalism: The refresh of the S and X introduced the yoke steering wheel and the stalk-less driving interface, design choices that polarized critics but influenced the broader industry.
The discontinuation of these models marks the end of Tesla’s “Phase 1,” where the goal was to prove the viability of the electric car. With that mission accomplished, the company is liquidating the symbols of that era to fund and house “Phase 2”: ubiquitous autonomy.
Supply Chain and Inventory Implications
The thinning of options like Lunar Silver also speaks to the logistical reality of shutting down an automotive production line. Unlike a software update, stopping a car line involves a complex web of suppliers. Tesla must coordinate with vendors who provide the unique stampings, glass, and interior trims specific to the S and X.
By narrowing the available configurations, Tesla reduces the risk of being left with “orphaned” parts—components that cannot be used on the Model 3, Model Y, or Cybertruck. This inventory management strategy is standard practice in the industry but is particularly aggressive in this case due to the urgency of the Optimus timeline. We can expect further restrictions in the coming weeks:
- Interior Choices: Niche interior colors like Cream or specific wood trims may be the next to vanish.
- Wheel Options: The company may standardize wheel offerings to clear out remaining stock of 20-inch or 22-inch rims.
- Seating Layouts: The Model X’s various seating configurations (5, 6, or 7 seats) create significant manufacturing complexity. It is highly probable that Tesla will lock production to the most popular configuration (likely the 6 or 7-seat variants) for the final run.
The Market Reaction: Collectibility and Value
The announcement of the production end date and the subsequent removal of options has triggered a unique reaction in the used and new car markets. Enthusiasts and collectors are beginning to view the final production run of the Model S and Model X—particularly the Plaid variants—as potential collector's items. The “Last Edition” effect could spur a temporary spike in demand as buyers rush to secure a brand-new unit before the factory lines halt forever.
Conversely, current owners are watching residual values closely. While the technology in the S and X is advanced, the cessation of the model line raises questions about long-term parts availability, although Tesla is legally required to supply parts for a significant duration. However, the prestige of owning the “flagship” Tesla may transition into owning a piece of history, potentially stabilizing depreciation for well-maintained examples.
Fremont’s Transformation: From Cars to Bots
The physical transformation of the Fremont Factory will be one of the most significant industrial retooling efforts of the decade. Originally built by GM, then operated as NUMMI with Toyota, and finally saved by Tesla, the factory has always been a car plant. Converting the General Assembly lines of the Model S and X into clean-room-style assembly areas for Optimus represents a new chapter.
Optimus requires different assembly techniques. While cars require heavy stamping presses and welding robots for steel and aluminum chassis, humanoid robots require precision assembly of actuators, batteries, and sensors. The volume density is also different; a robot takes up a fraction of the space of a luxury SUV, allowing Tesla to hit that 1 million unit target within the same physical footprint.
This shift aligns with Tesla’s valuation narrative. Wall Street has increasingly valued Tesla not just on automotive margins, but on the potential of its AI software and robotics hardware. By sacrificing the low-volume S and X to accelerate Optimus, Musk is doubling down on the bet that labor-replacing robotics will be a larger market than personal transportation.
Conclusion
The removal of the Lunar Silver paint option is a small detail with massive implications. It serves as the first strike of the clock signaling the final hour for the Model S and Model X. These vehicles, which carried Tesla through its most precarious years and fundamentally changed the automotive landscape, are being retired to make room for the future.
As the quarter ends and production winds down, we are witnessing a rare moment in industrial history: a company cannibalizing its most prestigious products to pivot toward a completely new product category. For those looking to own a brand-new Model S or X, the window is closing rapidly. The options are thinning, the lines are stopping, and the robots are coming.
