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.

Tesla aims to combat common Full Self-Driving problem with new patent
Tesla writes in the patent that its autonomous and semi-autonomous vehicles are heavily reliant on camera systems to navigate and interact with their environment.
Tesla is aiming to combat a common Full Self-Driving problem with a new patent.
One issue with Tesla’s vision-based approach is that sunlight glare can become a troublesome element of everyday travel. Full Self-Driving is certainly an amazing technology, but there are still things Tesla is aiming to figure out with its development.
Unfortunately, it is extremely difficult to get around this issue, and even humans need ways to combat it when they’re driving, as we commonly use sunglasses or sun visors to give us better visibility.
Cameras obviously do not have these ways to fight sunglare, but a new patent Tesla recently had published aims to fight this through a “glare shield.”
Tesla writes in the patent that its autonomous and semi-autonomous vehicles are heavily reliant on camera systems to navigate and interact with their environment.
The ability to see surroundings is crucial for accurate performance, and glare is one element of interference that has yet to be confronted.
Tesla described the patent, which will utilize “a textured surface composed of an array of micro-cones, or cone-shaped formations, which serve to scatter incident light in various directions, thereby reducing glare and improving camera vision.”
The patent was first spotted by Not a Tesla App.
The design of the micro-cones is the first element of the puzzle to fight the excess glare. The patent says they are “optimized in size, angle, and orientation to minimize Total Hemispherical Reflectance (THR) and reflection penalty, enhancing the camera’s ability to accurately interpret visual data.”
Additionally, there is an electromechanical system for dynamic orientation adjustment, which will allow the micro-cones to move based on the angle of external light sources.
This is not the only thing Tesla is mulling to resolve issues with sunlight glare, as it has also worked on two other ways to combat the problem. One thing the company has discussed is a direct photon count.
CEO Elon Musk said during the Q2 Earnings Call:
“We use an approach which is direct photon count. When you see a processed image, so the image that goes from the sort of photon counter — the silicon photon counter — that then goes through a digital signal processor or image signal processor, that’s normally what happens. And then the image that you see looks all washed out, because if you point the camera at the sun, the post-processing of the photon counting washes things out.”
Future Hardware iterations, like Hardware 5 and Hardware 6, could also integrate better solutions for the sunglare issue, such as neutral density filters or heated lenses, aiming to solve glare more effectively.

Delaware Supreme Court reinstates Elon Musk’s 2018 Tesla CEO pay package
The unanimous decision criticized the prior total rescission as “improper and inequitable,” arguing that it left Musk uncompensated for six years of transformative leadership at Tesla.
The Delaware Supreme Court has overturned a lower court ruling, reinstating Elon Musk’s 2018 compensation package originally valued at $56 billion but now worth approximately $139 billion due to Tesla’s soaring stock price.
The unanimous decision criticized the prior total rescission as “improper and inequitable,” arguing that it left Musk uncompensated for six years of transformative leadership at Tesla. Musk quickly celebrated the outcome on X, stating that he felt “vindicated.” He also shared his gratitude to TSLA shareholders.
Delaware Supreme Court makes a decision
In a 49-page ruling Friday, the Delaware Supreme Court reversed Chancellor Kathaleen McCormick’s 2024 decision that voided the 2018 package over alleged board conflicts and inadequate shareholder disclosures. The high court acknowledged varying views on liability but agreed rescission was excessive, stating it “leaves Musk uncompensated for his time and efforts over a period of six years.”
The 2018 plan granted Musk options on about 304 million shares upon hitting aggressive milestones, all of which were achieved ahead of time. Shareholders overwhelmingly approved it initially in 2018 and ratified it once again in 2024 after the Delaware lower court struck it down. The case against Musk’s 2018 pay package was filed by plaintiff Richard Tornetta, who held just nine shares when the compensation plan was approved.
A hard-fought victory
As noted in a Reuters report, Tesla’s win avoids a potential $26 billion earnings hit from replacing the award at current prices. Tesla, now Texas-incorporated, had hedged with interim plans, including a November 2025 shareholder-approved package potentially worth $878 billion tied to Robotaxi and Optimus goals and other extremely aggressive operational milestones.
The saga surrounding Elon Musk’s 2018 pay package ultimately damaged Delaware’s corporate appeal, prompting a number of high-profile firms, such as Dropbox, Roblox, Trade Desk, and Coinbase, to follow Tesla’s exodus out of the state. What added more fuel to the issue was the fact that Tornetta’s legal team, following the lower court’s 2024 decision, demanded a fee request of more than $5.1 billion worth of TSLA stock, which was equal to an hourly rate of over $200,000.

Tesla Cybercab tests are going on overdrive with production-ready units
Tesla is ramping its real-world tests of the Cybercab, with multiple sightings of the vehicle being reported across social media this week.
Tesla is ramping its real-world tests of the Cybercab, with multiple sightings of the autonomous two-seater being reported across social media this week. Based on videos of the vehicle that have been shared online, it appears that Cybercab tests are underway across multiple states.
Recent Cybercab sightings
Reports of Cybercab tests have ramped this week, with a vehicle that looked like a production-ready prototype being spotted at Apple’s Visitor Center in California. The vehicle in this sighting was interesting as it was equipped with a steering wheel. The vehicle also featured some changes to the design of its brake lights.
The Cybercab was also filmed testing at the Fremont factory’s test track, which also seemed to involve a vehicle that looked production-ready. This also seemed to be the case for a Cybercab that was spotted in Austin, Texas, which happened to be undergoing real-world tests. Overall, these sightings suggest that Cybercab testing is fully underway, and the vehicle is really moving towards production.
Production design all but finalized?
Recently, a near-production-ready Cybercab was showcased at Tesla’s Santana Row showroom in San Jose. The vehicle was equipped with frameless windows, dual windshield wipers, powered butterfly door struts, an extended front splitter, an updated lightbar, new wheel covers, and a license plate bracket. Interior updates include redesigned dash/door panels, refined seats with center cupholders, updated carpet, and what appeared to be improved legroom.
There seems to be a pretty good chance that the Cybercab’s design has been all but finalized, at least considering Elon Musk’s comments at the 2025 Annual Shareholder Meeting. During the event, Musk confirmed that the vehicle will enter production around April 2026, and its production targets will be quite ambitious.
