Tesla Model S Plaid battery pack shows that 18650 cell innovations are not over yet
A picture of the Tesla Model S Plaid’s 18650 battery pack with its modules visible was recently shared online. The image hinted that Tesla is still in the process of optimizing and innovating its 18650 battery technology, despite the cells being quite a bit long in the tooth.
Tesla is constantly trying to improve its battery technology, which has led to the development of the company’s highly-anticipated 4680 cells. The 4680 cells are expected to be used in vehicles that require a lot of power such as the Semi, Cybertruck, and new Roadster. Amidst the ongoing supply chain challenges and delays in the mass production of 4680 cells from Tesla’s Kato Road facility, however, the company noted that the Model S Plaid, its current flagship sedan, will maintain its use of 18650 batteries.
According to Redditor u/punx, who posted the picture, the Model S Plaid’s battery pack features five large modules, packed to the brim with Panasonic’s 18650 cells. The Reddit user confirmed the cells were 18650 with measurements proving they were 18mm in diameter and 65mm in length. Previous iterations of the Model S have battery packs with as many as 16 individual modules.
A decrease in the number of modules in the Model S Plaid’s battery means fewer parts for the vehicle’s pack, resulting in lower production costs for Tesla. Lowering production costs for its vehicles is a key priority for the company. At the 2021 Annual Shareholders Meeting, Elon Musk mentioned that Tesla has been making a lot of progress in cost reduction, despite the average selling price going down due to the lower prices of vehicles like the Model 3 and Model Y.
“We managed to still do decently well on a gross margin. So, you know, getting the average price down and gross margin up is very difficult,” Musk pointed out. “But we’ve managed to do that. Our goal is really to make the cars as affordable as possible.”
The Model S Plaid (and perhaps the Model X Plaid) might be the last vehicles in Tesla’s lineup that would use 18650 cells. With Tesla focusing its efforts to master the mass production of its 4680 cells — which are more powerful and cheaper to produce — it would not be a surprise if future iterations of the flagship sedan and SUV are fitted with 4680 structural batteries. The 18650 cells are showing their age, after all, as Tesla has been using them since the days of the original Roadster.
If Tesla does utilize its 4680 cells for the Model S and Model X, the vehicles would likely be equipped with nickel-based batteries. The Tesla CEO has previously explained that the supply chain goes all the way back to raw materials like lithium and nickel, which are used to develop the company’s battery cells. During the last earnings call, Elon Musk mulled over the idea of Tesla consolidating its battery offerings down to 2 or 3 form factors, one nickel-based for high-powered vehicles like the Semi and the other iron-based for mass-produced cars like the Model 3.
“So right now, we kind of have the Baskin Robbins of batteries situation, where there’s so many formats and so many chemistries, that it’s like we’ve got like 36 flavors of battery at this point,” Musk said.
“This results in an engineering drag coefficient where each variants of cell chemistry and format requires as certain amount of engineering to maintain it and troubleshoot. And this inhibits our forward progress. So it is going to be important to consolidate to maybe—ideally two form factors, maybe three, but ideally two. And then just one nickel chemistry and one iron chemistry, so we don’t have to troubleshoot so many different variants,” he said.
With Tesla likely retiring its 18650 cells in the future, the Model S Plaid’s five-module battery pack could be seen as one of the final iterations of the technology that the company quite literally used to build its empire. And considering that the 18650 cells are being used in the Model S Plaid, there is no better swan song for the humble batteries.

Tesla has passed a critical self-driving milestone Elon Musk listed in Master Plan Part Deux
Tesla China announced that the company’s Autopilot system has accumulated 10 billion kilometers of driving experience.
Tesla has passed a key milestone, and it was one that CEO Elon Musk initially mentioned more than nine years ago when he published Master Plan, Part Deux.
As per Tesla China in a post on its official Weibo account, the company’s Autopilot system has accumulated over 10 billion kilometers of real-world driving experience.
Tesla China’s subtle, but huge announcement
In its Weibo post, Tesla China announced that the company’s Autopilot system has accumulated 10 billion kilometers of driving experience. “In this respect, Tesla vehicles equipped with Autopilot technology can be considered to have the world’s most experienced and seasoned driver.”
Tesla AI’s handle on Weibo also highlighted a key advantage of the company’s self-driving system. “It will never drive under the influence of alcohol, be distracted, or be fatigued,” the team wrote. “We believe that advancements in Autopilot technology will save more lives.”
Tesla China did not clarify exactly what it meant by “Autopilot” in its Weibo post, though the company’s intense focus on FSD over the past years suggests that the term includes miles that were driven by FSD (Beta) and Full Self-Driving (Supervised). Either way, 10 billion cumulative miles of real-world data is something that few, if any, competitors could compete with.


Elon Musk’s 10-billion-km estimate, way back in 2016
When Elon Musk published Master Plan Part Deux, he outlined his vision for the company’s autonomous driving system. At the time, Autopilot was still very new, though Musk was already envisioning how the system could get regulatory approval worldwide. He estimated that worldwide regulatory approval will probably require around 10 billion miles of real-world driving data, which was an impossible-sounding amount at the time.
“Even once the software is highly refined and far better than the average human driver, there will still be a significant time gap, varying widely by jurisdiction, before true self-driving is approved by regulators. We expect that worldwide regulatory approval will require something on the order of 6 billion miles (10 billion km). Current fleet learning is happening at just over 3 million miles (5 million km) per day,” Musk wrote.
It’s quite interesting but Tesla is indeed getting regulatory approval for FSD (Supervised) at a steady pace today, at a time when 10 billion miles of data has been achieved. The system has been active in the United States and has since been rolled out to other countries such as Australia, New Zealand, China, and, more recently, South Korea. Expectations are high that Tesla could secure FSD approval in Europe sometime next year as well.

SpaceX maintains unbelievable Starship target despite Booster 18 incident
It appears that it will take more than an anomaly to stop SpaceX’s march towards Starship V3’s refinement.
SpaceX recently shared an incredibly ambitious and bold update about Starship V3’s 12th test flight.
Despite the anomaly that damaged Booster 18, SpaceX maintained that it was still following its plans for the upgraded spacecraft and booster for the coming months. Needless to say, it appears that it will take more than an anomaly to stop SpaceX’s march towards Starship V3’s refinement.
Starship V3 is still on a rapid development path
SpaceX’s update was posted through the private space company’s official account on social media platform X. As per the company, “the Starbase team plans to have the next Super Heavy booster stacked in December, which puts it on pace with the test schedule planned for the first Starship V3 vehicle and associated ground systems.”
SpaceX then announced that Starship V3’s maiden flight is still expected to happen early next year. “Starship’s twelfth flight test remains targeted for the first quarter of 2026,” the company wrote in its post on X.
Elon Musk mentioned a similar timeline on X earlier this year. In the lead up to Starshp Flight 11, which proved flawless, Musk stated that “Starship V3 is a massive upgrade from the current V2 and should be through production and testing by end of year, with heavy flight activity next year.” Musk has also mentioned that Starship V3 should be good enough to use for initial Mars missions.
Booster 18 failure not slowing Starship V3’s schedule
SpaceX’s bold update came after Booster 18 experienced a major anomaly during gas system pressure testing at SpaceX’s Massey facility in Starbase, Texas. SpaceX confirmed in a post on X that no propellant was loaded, no engines were installed, and personnel were positioned at a safe distance when the booster’s lower section crumpled, resulting in no injuries.
Still, livestream footage showed significant damage around the liquid oxygen tank area of Booster 18, leading observers to speculate that the booster was a total loss. Booster 18 was among the earliest vehicles in the Starship V3 series, making the failure notable. Despite the setback, Starship V3’s development plans appear unchanged, with SpaceX pushing ahead of its Q1 2026 test flight target.

Tesla Sweden faces fresh union blockade at key Gothenburg paint shop
Allround Lack works with painting and damage repair of passenger cars, including Teslas.
Tesla’s ongoing labor conflict in Sweden escalated again as the trade union IF Metall issued a new blockade halting all Tesla paintwork at Allround Lack in Gothenburg.
Allround Lack works with painting and damage repair of passenger cars, including Teslas. It currently employs about 20 employees.
Yet another blockade against Tesla Sweden
IF Metall’s latest notice ordered a full work stoppage for all Tesla-related activity at Allround Lack. With the blockade in place, paint jobs on Tesla-owned vehicles, factory-warranty repairs, and transport-damage fixes, will be effectively frozen, as noted in a report from Dagens Arbete. While Allround Lack is a small paint shop, its work with Tesla means that the blockade would add challenges to the company’s operations in Sweden, at least to some degree.
Paint shop blockades have been a recurring tool in the longstanding conflict. The first appeared in late 2023, when repair shops were barred from servicing Tesla vehicles. Days later, the Painters’ Union implemented a nationwide halt on Tesla paint work across more than 100 shops. Since then, a steady stream of workshops has been pulled into the conflict.
Earlier blockades faced backlash from consumers
The sweeping effects of the early blockades drew criticism from industry groups and consumers. Employers and industry organization Transportföretagen stated that the strikes harmed numerous workshops across Sweden, with about 10 of its members losing about 50% of their revenue.
Private owners also expressed their objections. Tibor Blomhäll, chairman of Tesla Club Sweden, told DA in a previous statement that the blockades from IF Metall gave the impression that the union was specifically attacking consumers. “If I get parking damage to my car, I pay for the paint myself. The company Tesla is not involved in that deal at all. So many people felt singled out, almost stigmatized. What have I done as a private individual to get a union against me?” Blomhäll stated.
In response to these complaints, IF Metall introduced exemptions, allowing severely damaged vehicles to be repaired. The union later reopened access for private owners at workshops with collective agreements. The blockades at the workshops were also reformulated to only apply to work that is “ordered by Tesla on Tesla’s own cars, as well as work covered by factory warranties and transport damage on Tesla cars.”
