Tesla gives update for early FSD adopters with legacy Model S, Model X vehicles
Longtime Tesla FSD adopters with legacy vehicles recently received an update from the electric car maker. The update sheds some light on what is waiting for customers who purchased FSD and are still driving legacy Model S and Model X vehicles today.
Tesla functions like a tech company, so it is no surprise that it has moved very fast over the years. This means that constant improvements to its vehicles’ hardware are being implemented as soon as they are ready. This also means, however, that the latest updates to systems like FSD (Supervised) or Autopilot are mostly focused on vehicles that represent the majority of the company’s fleet.
This was highlighted by Elon Musk in a recent post on X, when he noted that while Tesla’s Hardware 4 will ultimately be better, all training that the company is doing right now is for Hardware 3 vehicles. Hardware 4 is just running on emulation mode.
Within Tesla’s pursuit of autonomous driving lies a group of Model S and Model X owners who bought into FSD even before the Model 3 was ramped. These owners were promised that their vehicles would have the necessary hardware to be self-driving one day, but they have not received much of Tesla’s Autopilot and FSD improvements to date. Granted, Tesla has launched a hardware upgrade program for legacy vehicles, but they are paid options that some owners have refused.
It was then no surprise that amidst the excitement for FSD (Supervised), some legacy Model S and Model X owners have expressed their frustration at being left out again. Among these is Anthony Spina, who noted in a post on X, that “all of us legacy S/X owners still haven’t received V12 yet, with no official communication stating whether or not we even will. MCU1 FSD S/X owners have been living in the dark on this for years, and now MCU2 owners are beginning to be lumped into this group as well, at least it would seem on the surface.”
Thanks @Speenuh and others who have posted on @X about this. While we normally prioritize our paid FSD customers to the extent possible, there is a group of S/X customers (~3% of total FSD eligible vehicles) who have a different hardware which the @Tesla_AI team is working to… https://t.co/W3l3SYlVZu— Rohan Patel (@rohanspatel) March 31, 2024
In a response on X, Tesla Vice President of Public Policy and Business Development Rohan Patel explained that the electric vehicle maker is putting a lot of efforts into releasing systems like FSD (Supervised) to older vehicles. The executive noted that Tesla cannot give a timeline as to when FSD would be released to older vehicles, but the company’s AI team is working on it.
“Thanks @Speenuh and others who have posted on @X about this. While we normally prioritize our paid FSD customers to the extent possible, there is a group of S/X customers (~3% of total FSD eligible vehicles) who have a different hardware which the @Tesla_AI team is working to validate. We have a rigorous safety validation cycle for every software update, and we are working as hard as possible to ship the latest builds to all customers. We don’t want to give false precision on timing until the validation can be completed, but want you to know we are focused on trying to solve this. Many of you have been with us on the FSD journey from the start and it’s super appreciated,” Patel wrote.
We ? get it and understand and sincerely appreciate the patience. Our software engineers and validation teams really are doing all they can to try and solve even on Easter Sunday.— Rohan Patel (@rohanspatel) March 31, 2024
In a follow-up post, the Tesla executive also noted that the company understands the frustration of its legacy customers. “We 100% get it and understand and sincerely appreciate the patience. Our software engineers and validation teams really are doing all they can to try and solve even on Easter Sunday,” the executive noted.

Tesla AI5 chip nears completion, Elon Musk teases 9-month development cadence
The Tesla CEO shared his recent insights in a post on social media platform X.
Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk.
The Tesla CEO shared his recent insights in a post on social media platform X.
Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.

This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.

Tesla Sweden uses Megapack battery to bypass unions’ Supercharger blockade
Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery.
Tesla Sweden has successfully launched a new Supercharger station despite an ongoing blockade by Swedish unions, using on-site Megapack batteries instead of traditional grid connections. The workaround has allowed the Supercharger to operate without direct access to Sweden’s electricity network, which has been effectively frozen by labor action.
Tesla has experienced notable challenges connecting its new charging stations to Sweden’s power grid due to industrial action led by Seko, a major Swedish trade union, which has blocked all new electrical connections for new Superchargers. On paper, this made the opening of new Supercharger sites almost impossible.
Despite the blockade, Tesla has continued to bring stations online. In Malmö and Södertälje, new Supercharger locations opened after grid operators E.ON and Telge Nät activated the sites. The operators later stated that the connections had been made in error.
More recently, however, Tesla adopted a different strategy altogether. Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery, as noted in a Dagens Arbete (DA) report.
Because the Supercharger station does not rely on a permanent grid connection, Tesla was able to bypass the blocked application process, as noted by Swedish car journalist and YouTuber Peter Esse. He noted that the Arlandastad Supercharger is likely dependent on nearby companies to recharge the batteries, likely through private arrangements.
Eight new charging stalls have been launched in the Arlandastad site so far, which is a fraction of the originally planned 40 chargers for the location. Still, the fact that Tesla Sweden was able to work around the unions’ efforts once more is impressive, especially since Superchargers are used even by non-Tesla EVs.
Esse noted that Tesla’s Megapack workaround is not as easily replicated in other locations. Arlandastad is unique because neighboring operators already have access to grid power, making it possible for Tesla to source electricity indirectly. Still, Esse noted that the unions’ blockades have not affected sales as much.
“Many want Tesla to lose sales due to the union blockades. But you have to remember that sales are falling from 2024, when Tesla sold a record number of cars in Sweden. That year, the unions also had blockades against Tesla. So for Tesla as a charging operator, it is devastating. But for Tesla as a car company, it does not matter in terms of sales volumes. People charge their cars where there is an opportunity, usually at home,” Esse noted.
