Tesla’s 75 kWh battery pack removal opens doors to ‘Track Mode’ for Model S & X
In a recent update on Twitter, Elon Musk announced that Tesla would be discontinuing the 75 kWh variants of the Model S and Model X. Starting this coming Monday, Tesla’s two flagship vehicles would only be offered at 100 kWh and 100 kWh Performance versions, widening the price gap between the cars and the company’s newest offering — the Model 3.
In a way, retiring the 75D line seems to be the right decision for Tesla. After all, the Model S 75D, which is priced at $76,000 before options, pretty much overlaps with the price of a fully-loaded Model 3 Performance. That said, this change also results in the base price of the Model S and Model X increasing significantly. The Model S 100D — the vehicle’s base version starting Monday — would start at $94,000, while the Model X 100D would start at $97,000, far higher than the Model X 75D’s starting price of $82,000.
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 https://t.co/46TXqRJ3C1

Apart from widening the gap between the more affordable Model 3 and the flagship Model S and X, though, the retirement of the 75 kWh battery pack also opens the doors to a very likely battery upgrade for the full-size sedan and SUV. The Model S and X, after all, are still equipped with 18650 cells, which are smaller and a bit older than the 2170 cells being used on the Model 3. These cells are also imported from Panasonic’s facilities in Japan, instead of being produced in Gigafactory 1.
By retiring the 75 kWh battery pack, Tesla would give itself an opportunity to roll out the newer cells to its flagship vehicles. The 2170 cells, for one, would probably even allow the Performance-branded Model S and X to handle extended track driving. Part of the reason behind the current generation Model S and X’s inability to be competitive on the track, after all, is their batteries, which have a tendency to overheat after a few laps around a closed circuit. This particular issue has been largely addressed by Tesla with the Model 3 and its 2170 cells, as evidenced by the vehicle’s dedicated Track Mode setting.
A Track Mode feature for the Performance Model S and X would make the vehicles even more fearsome than they already are. Even with their general inability to be driven on a racecourse, the Model S and Model X have nonetheless developed a reputation as monsters in straight-line races over the years. Equipped with a battery that has the same tech as the Model 3 — from its 2170 cells to its clever cooling systems — the Model S and X would be downright frightening.
Apart from opening the doors to Track Mode, an update to 2170 cells would likely result in more range for the Model S and Model X as well. This is something that Tesla could definitely use as a selling point for its flagship vehicles, considering that the competition, including the Porsche Taycan and the Jaguar I-PACE, are still pretty much competing against the bar set by vehicles that were created during the 18650 cell era. One can only speculate how much range a Long Range version of the Model S would have if it were equipped with 2170 cells. Perhaps even a 400-mile range? Such a scenario is plausible.
Hidden within this new update from Elon Musk, though, is something that bodes well for the company’s upcoming vehicle — the Model Y. Seeing as Tesla retired the Model X 75D, the company’s only SUV in its lineup now starts at $97,000. That’s very expensive, and this price notably reduces the size of the vehicle’s potential consumer base in an incredibly popular segment. By adopting this strategy at this point, Tesla appears to be hinting at the release of another, more affordable SUV that can compete more aggressively than the entry-level Model X. This vehicle, of course, would be the Model Y.
The Model Y has been in the rumor mill for some time now. In recent months, though, Elon Musk has provided a number of updates on the vehicle. During the company’s third-quarter earnings call, for one, Musk mentioned that he had already approved the construction of the Model Y’s alpha prototype. Musk has also joked that the upcoming SUV would be unveiled this 2018, perhaps sometime in the first half of the year.
SpaceX is preparing for the 13th integrated flight test of its Starship system, with a targeted launch as early as Thursday, July 16. The 90-minute launch window opens at 5:45 p.m. CT from Starbase in South Texas.
This comes roughly seven weeks after Flight 12 on May 22, underscoring the company’s accelerating pace in its rapid development campaign. The mission will use the latest Starship and Super Heavy V3 vehicles equipped with Raptor 3 engines. Booster 20 will attempt a controlled boostback burn, followed by a splashdown in the Gulf of Mexico, while Ship 40 will follow a suborbital trajectory.

Key objectives for Flight 13 will include demonstrating reliable stage separation, engine performance under various conditions, and controlled reentry.
A major milestone for Flight 13 is the first deployment of 20 next-generation Starlink V3 satellites. These satellites feature advanced laser links for inter-satellite communication, deployable solar arrays, and onboard cameras, six of which will capture imagery of Starship’s heat shield during flight.
Several heat shield tiles on Ship 40 will be painted white to serve as imaging targets, while additional experiments test upgraded tiles on aft flaps, modified attachments on the aft skirt, and load-sensing tiles to measure stresses. The upper stage will also attempt a single Raptor engine relight in space before a targeted splashdown in the Indian Ocean.
These tests build directly on lessons from Flight 12, which introduced the V3 configuration but encountered issues including a booster flip anomaly during boostback and an engine-out event on the ship. Hardware and software modifications on Booster 20 and Ship 40 aim to improve engine relight reliability, startup sequencing, and overall robustness.

The short interval between Flights 12 and 13 highlights SpaceX’s iterative approach. Elon Musk has repeatedly emphasized that Starship launches will become “incredibly common” in the coming years.
The company envisions scaling to rates as high as one launch per hour within 4-5 years, potentially enabling thousands of flights annually. Such cadence is essential for Starship’s goals: establishing orbital refueling for lunar and Mars missions, deploying massive satellite constellations, and making life multiplanetary.
With each flight, Starship edges closer to full reusability and operational maturity. Success on July 16 would mark another step toward routine access to space and the ambitious vision of humanity becoming a spacefaring civilization.
Tesla shared a striking video showcasing the decommissioning of the original Model S and Model X assembly line at its Fremont Factory in Northern California. Completed in just 46 days, the teardown involved heavy machinery dismantling concrete pits, removing robotic arms and conveyors, and clearing the space for new production.
The post, captioned “End of an era,” captured both the end of a historic chapter and Tesla’s aggressive pivot toward its next major initiative, Optimus.

The decision to retire the Model S and Model X originated during Tesla’s Q4 2025 Earnings Call in late January 2026. CEO Elon Musk announced that production of the company’s flagship sedan and SUV would wind down by the end of Q2 2026, describing it as bringing the programs to an “honorable discharge.”
Custom orders ceased around early April 2026, with the final vehicles rolling off the line in early May. A special signature delivery ceremony on May 20 marked the emotional close for these vehicles, which had defined Tesla’s early success and luxury EV segment since the Model S launch in 2012.
The primary reason for tearing down the lines was to repurpose the valuable factory floor space for high-volume production of Tesla’s Optimus humanoid robot. Musk had indicated on Earnings Calls that the Fremont S/X line would be replaced by a dedicated Optimus manufacturing line targeting a capacity of one million units per year.
This move aligns with Tesla’s broader strategic shift from traditional vehicle manufacturing toward robotics and artificial intelligence, leveraging the company’s expertise in autonomy, AI training, and high-volume production.
Optimus, Tesla’s general-purpose humanoid robot, is designed to perform repetitive or dangerous tasks in factories, warehouses, and eventually homes. Powered by Tesla’s AI and Neural Networks, it aims to be a versatile, affordable platform. Production of Optimus Gen 3 is already underway in limited form at Fremont, with full-scale output on the converted line expected to begin in late July or August.
Tesla is targeting rapid scaling, with internal ambitions pointing toward tens or even hundreds of thousands of units annually by the end of 2026.
Longer-term, Tesla is constructing a much larger second-generation Optimus facility at Giga Texas, with potential capacity reaching millions of units per year. The company views Optimus as a transformative product that could eventually surpass its automotive business in scale and value, enabling widespread deployment of useful robots across industries. CEO Elon Musk has even predicted it would be the most popular product of all-time.
As one era closes at Fremont, another is rapidly taking shape.
Elon Musk posted a candid admission on his social media platform X on June 9, declaring that he had been “clearly wrong” about Anthropic. The statement marked a notable reversal from his earlier skepticism toward the AI company.
In September, Musk had written, “Winning was never in the set of possible outcomes for Anthropic,” reflecting his view at the time that the startup had lacked the foundation or even the trajectory to succeed in what is an incredibly intense race for advanced artificial intelligence.
Musk’s latest post came amid discussion of Anthropic’s reliance on external compute resources. He praised the company’s progress, stating that Anthropic is “obviously currently the leader in AI” and that “no company has released a model as good as Mythos/Fable,” with expectations of a strong follow-up in Mythos 2.
The tone shifted dramatically from dismissal to acknowledgement of superior performance.
I was clearly wrong about Anthropic. They are obviously currently the leader in AI. No company has released a model as good as Mythos/Fable and they will undoubtedly have Mythos 2 ready soon.
And I would never cut them off in a way that hurt them badly, even as a competitor.…

The context of Musk’s comments added significance. Anthropic has been operating under a recent compute deal with SpaceXAI, Musk’s AI infrastructure-focused venture. The pair entered a short-term GPU lease agreement initiated in May, providing Anthropic access to critical computing power for training and deploying its frontier models.

Some observers had speculated that Musk could leverage this dependency to disadvantage a rival. Musk directly addressed the possibility, writing, “I would never cut them off in a way that hurt them badly, even as a competitor. That’s not my style.”
To support his commitment to ethical competition, Musk referenced concrete examples from his other companies. Tesla famously open-sourced its entire portfolio of electric vehicle patents in 2014. The move was designed to accelerate the global adoption of sustainable transportation technology rather than protect proprietary advantages.
Tesla also made its Supercharger network available to competing electric vehicle manufacturers, transforming what could have remained an exclusive charging ecosystem into a shared infrastructure that benefits the broader industry and reduces barriers for EV adoption.
Musk further pointed to SpaceX’s practices, noting that the company launches satellites for competing commercial systems “with no increase in price or use of unfair terms.” He extended the principle to his social platform, observing that “even my worst enemies attack me on this platform,” underscoring preference for open discourse over retaliation.
These examples have illustrated Musk’s long-standing philosophy that long-term technological progress is best served by open competition and infrastructure sharing rather than leveraging market power to stifle rivals. In the fast-evolving AI sector, where compute resources and model capabilities determine leadership, Musk’s stance suggests a willingness to compete on innovation and performance alone.
Musk’s admission arrives as SpaceXAI itself advances its own frontier models while maintaining business relationships across the ecosystem. By publicly correcting his earlier assessment and reaffirming principles of fair play, Musk highlights a model of competition that prioritizes advancement of the field over short-term tactical advantages.
