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 issues statement on Starship V3 Booster 18 anomaly
The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX has issued an initial statement about Starship Booster 18’s anomaly early Friday. The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX’s initial comment
As per SpaceX in a post on its official account on social media platform X, Booster 18 was undergoing gas system pressure tests when the anomaly happened. Despite the nature of the incident, the company emphasized that no propellant was loaded, no engines were installed, and personnel were kept at a safe distance from the booster, resulting in zero injuries.
“Booster 18 suffered an anomaly during gas system pressure testing that we were conducting in advance of structural proof testing. No propellant was on the vehicle, and engines were not yet installed. The teams need time to investigate before we are confident of the cause. No one was injured as we maintain a safe distance for personnel during this type of testing. The site remains clear and we are working plans to safely reenter the site,” SpaceX wrote in its post on X.
Incident and aftermath
Livestream footage from LabPadre showed Booster 18’s lower half crumpling around the liquid oxygen tank area at approximately 4:04 a.m. CT. Subsequent images posted by on-site observers revealed extensive deformation across the booster’s lower structure. Needless to say, spaceflight observers have noted that Booster 18 would likely be a complete loss due to its anomaly.
Booster 18 had rolled out only a day earlier and was one of the first vehicles in the Starship V3 program. The V3 series incorporates structural reinforcements and reliability upgrades intended to prepare Starship for rapid-reuse testing and eventual tower-catch operations. Elon Musk has been optimistic about Starship V3, previously noting on X that the spacecraft might be able to complete initial missions to Mars.

Tesla analyst maintains $500 PT, says FSD drives better than humans now
The team also met with Tesla leaders for more than an hour to discuss autonomy, chip development, and upcoming deployment plans.
Tesla (NASDAQ:TSLA) received fresh support from Piper Sandler this week after analysts toured the Fremont Factory and tested the company’s latest Full Self-Driving software. The firm reaffirmed its $500 price target, stating that FSD V14 delivered a notably smooth robotaxi demonstration and may already perform at levels comparable to, if not better than, average human drivers.
The team also met with Tesla leaders for more than an hour to discuss autonomy, chip development, and upcoming deployment plans.
Analysts highlight autonomy progress
During more than 75 minutes of focused discussions, analysts reportedly focused on FSD v14’s updates. Piper Sandler’s team pointed to meaningful strides in perception, object handling, and overall ride smoothness during the robotaxi demo.
The visit also included discussions on updates to Tesla’s in-house chip initiatives, its Optimus program, and the growth of the company’s battery storage business. Analysts noted that Tesla continues refining cost structures and capital expenditure expectations, which are key elements in future margin recovery, as noted in a Yahoo Finance report.
Analyst Alexander Potter noted that “we think FSD is a truly impressive product that is (probably) already better at driving than the average American.” This conclusion was strengthened by what he described as a “flawless robotaxi ride to the hotel.”
Street targets diverge on TSLA
While Piper Sandler stands by its $500 target, it is not the highest estimate on the Street. Wedbush, for one, has a $600 per share price target for TSLA stock.
Other institutions have also weighed in on TSLA stock as of late. HSBC reiterated a Reduce rating with a $131 target, citing a gap between earnings fundamentals and the company’s market value. By contrast, TD Cowen maintained a Buy rating and a $509 target, pointing to strong autonomous driving demonstrations in Austin and the pace of software-driven improvements.
Stifel analysts also lifted their price target for Tesla to $508 per share over the company’s ongoing robotaxi and FSD programs.

SpaceX Starship Version 3 booster crumples in early testing
Photos of the incident’s aftermath suggest that Booster 18 will likely be retired.
SpaceX’s new Starship first-stage booster, Booster 18, suffered major damage early Friday during its first round of testing in Starbase, Texas, just one day after rolling out of the factory.
Based on videos of the incident, the lower section of the rocket booster appeared to crumple during a pressurization test. Photos of the incident’s aftermath suggest that Booster 18 will likely be retired.
Booster test failure
SpaceX began structural and propellant-system verification tests on Booster 18 Thursday night at the Massey’s Test Site, only a few miles from Starbase’s production facilities, as noted in an Ars Technica report. At 4:04 a.m. CT on Friday, a livestream from LabPadre Space captured the booster’s lower half experiencing a sudden destructive event around its liquid oxygen tank section. Post-incident images, shared on X by @StarshipGazer, showed notable deformation in the booster’s lower structure.
Neither SpaceX nor Elon Musk had commented as of Friday morning, but the vehicle’s condition suggests it is likely a complete loss. This is quite unfortunate, as Booster 18 is already part of the Starship V3 program, which includes design fixes and upgrades intended to improve reliability. While SpaceX maintains a rather rapid Starship production line in Starbase, Booster 18 was generally expected to validate the improvements implemented in the V3 program.
Tight deadlines
SpaceX needs Starship boosters and upper stages to begin demonstrating rapid reuse, tower catches, and early operational Starlink missions over the next two years. More critically, NASA’s Artemis program depends on an on-orbit refueling test in the second half of 2026, a requirement for the vehicle’s expected crewed lunar landing around 2028.
While SpaceX is known for diagnosing failures quickly and returning to testing at unmatched speed, losing the newest-generation booster at the very start of its campaign highlights the immense challenge involved in scaling Starship into a reliable, high-cadence launch system. SpaceX, however, is known for getting things done quickly, so it would not be a surprise if the company manages to figure out what happened to Booster 18 in the near future.
