Tesla owner upgrades Autopilot 2.5 to 3.0 Hardware: Cost, results, and more
Back in October 2018, Elon Musk stated on Twitter that Tesla owners with HW2.5 vehicles who purchased the Full Self-Driving suite will be receiving a free upgrade to the company’s custom-designed, homegrown HW3 Autopilot computer. Today, Tesla appears to be staying true to the CEO’s word, as recently shared by a Model X owner from Canada.
A Tesla Model X P100D owner who runs the Electric Dreams channel on YouTube recently received the company’s latest iteration of its V10 software. Being equipped with Hardware 2.5, the Model X was not able to take advantage of some new features that were rolled out by the electric car maker, such as the company’s updated driving visualizations improvements.
This was a bit disappointing for the Model X owner, especially since his vehicle was equipped with Tesla’s Full Self-Driving suite. With this, the owner-enthusiast opted to schedule a home visit from a Tesla Mobile Service technician. The request: to conduct a retrofit that would replace the Model X P100D’s HW2.5 computer with Tesla’s newer, more powerful, custom-designed HW3 FSD unit.
Commenting on the experience, the Tesla owner noted that he was not really expecting Tesla to respond to his request, but much to his pleasant surprise, an appointment was indeed processed. After signing some documents, it did not take long before a member of Tesla’s Mobile Service Team drove over to the Model X owner’s house to conduct a HW2.5 to HW3 retrofit on the all-electric SUV.

Unfortunately, the Model X owner was informed that no videos were allowed during the entire HW3 retrofit process. Nevertheless, images taken by the Electric Dreams host during the new Autopilot computer’s installation show that Tesla’s HW3 does seem more robust than the NVIDIA-powered HW2.5, with its large radiators and somewhat heftier look. It took around an hour and a half for the installation to be completed and an additional two hours for the necessary firmware to be loaded into the vehicle.
After this was completed, the Model X P100D was updated once more with Tesla’s latest software. And sure enough, features that were unavailable prior to the HW2.5 to HW3 retrofit, such as V10’s driving visualizations improvements, were now enabled. Overall, it appears that Tesla’s HW3 retrofits for Model S and Model X owners who purchased the FSD suite seem to be ongoing now, and true to Elon Musk’s words, the process is completely painless. The entire upgrade was free as well, as indicated by the $0 charge for the HW3 installation.
Yet, perhaps the best thing here really is the sheer convenience of the entire retrofit process. Back in September, Tesla owner-enthusiast Sofiaan Fraval noted on Twitter that his Model S received a HW3 retrofit when he paid a visit to the service center. If the Electric Dreams channel host’s video is any indication, it appears that retrofits are now being conducted by Tesla’s Mobile Service team, and they are also available on demand.
This ultimately bodes well for Tesla’s rollout of its Full Self-Driving suite. Musk, after all, has stated that the company will push HW3 retrofits when FSD features actually warrant the additional computing power of the custom-built Autopilot unit. This was explained by Musk in a tweet back in March. “Retrofits will start when our software is able to take meaningful advantage of the Tesla FSD computer, which is an order of magnitude more capable. For now, it’s slightly disadvantageous to have Tesla FSD computer as our software is more refined for HW2,” Musk wrote.
Considering the company’s rollout of new FSD features such as Smart Summon, it appears that HW3’s additional computing power is now becoming more useful for Tesla’s advanced capabilities.

Tesla hiring Body Fit Technicians for Cybercab’s end of line
As per Tesla’s Careers website, Body Fit Technicians for the Cybercab focus on precision body fitment work, including alignment, gap and flush adjustments.
Tesla has posted job openings for Body Fit Technicians for the Cybercab’s end-of-line assembly, an apparent indication that preparations for the vehicle’s initial production are accelerating at Giga Texas.
Body Fit Technicians for Cybercab line
As per Tesla’s Careers website, Body Fit Technicians for the Cybercab focus on precision body fitment work, including alignment, gap and flush adjustments, and certification of body assemblies to specification standards.
Employees selected for the role will collaborate with engineering and quality teams to diagnose and correct fitment and performance issues and handle detailed inspections, among other tasks.
The listing noted that candidates should be experienced with automotive body fit techniques and comfortable with physically demanding tasks such as lifting, bending, walking, and using both hand and power tools. The position is based in Austin, Texas, where Tesla’s main Cybercab production infrastructure is being built.
Cybercab poised for April production
Tesla CEO Elon Musk recently reiterated that the Cybercab is still expected to start initial production this coming April. So far, numerous Cybercab test units have been spotted across the United States, and recent posts from the official Tesla Robotaxi account have revealed that winter tests in Alaska for the autonomous two-seater are underway.
While April has been confirmed as the date for the Cybercab’s initial production, Elon Musk has also set expectations about the vehicle’s volumes in its initial months. As per the CEO, the Cybercab’s production will follow a typical S-curve, which means that early production rates for the vehicle will be very limited.
“Initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast,” Musk wrote in a post on X.

Swedish unions consider police report over Tesla Megapack Supercharger
The Tesla Megapack Supercharger opened shortly before Christmas in Arlandastad, outside Stockholm.
Swedish labor unions are considering whether to file a police report related to a newly opened Tesla Megapack Supercharger near Stockholm, citing questions about how electricity is supplied to the site. The matter has also been referred to Sweden’s energy regulator.
Tesla Megapack Supercharger
The Tesla Megapack Supercharger opened shortly before Christmas in Arlandastad, outside Stockholm. Unlike traditional charging stations, the site is powered by an on-site Megapack battery rather than a direct grid connection. Typical grid connections for Tesla charging sites in Sweden have seen challenges for nearly two years due to union blockades.
Swedish labor union IF Metall has submitted a report to the Energy Market Inspectorate, asking the authority to assess whether electricity supplied to the battery system meets regulatory requirements, as noted in a report from Dagens Arbete (DA). The Tesla Megapack on the site is charged using electricity supplied by a local company, though the specific provider has not been publicly identified.
Peter Lydell, an ombudsman at IF Metall, issued a comment about the Tesla Megapack Supercharger. “The legislation states that only companies that engage in electricity trading may supply electricity to other parties. You may not supply electricity without a permit, then you are engaging in illegal electricity trading. That is why we have reported this… This is about a company that helps Tesla circumvent the conflict measures that exist. It is clear that it is troublesome and it can also have consequences,” Lydell said.
Police report under consideration
The Swedish Electricians’ Association has also examined the Tesla Megapack Supercharger and documented its power setup. As per materials submitted to the Energy Market Inspectorate, electrical cables were reportedly routed from a property located approximately 500 meters from the charging site.
Tomas Jansson, ombudsman and deputy head of negotiations at the Swedish Electricians’ Association, stated that the union was assessing whether to file a police report related to the Tesla Megapack Supercharger. He also confirmed that the electricians’ union was coordinating with IF Metall about the matter. “We have a close collaboration with IF Metall, and we are currently investigating this. We support IF Metall in their fight for fair conditions at Tesla,” Jansson said.

Tesla HW4.5 spotted in new Model Y, triggers speculation
Owners taking delivery of recent Model Y builds have identified components labeled “AP45.”
Tesla’s Hardware 4.5 computer appears to have surfaced in newly delivered Model Y vehicles, prompting fresh speculation about an interim upgrade ahead of the company’s upcoming AI5 chip.
Owners taking delivery of recent Model Y builds have identified components labeled “AP45,” suggesting Tesla may have quietly started rolling out revised autonomy hardware.
Hardware 4.5 appears in new Model Y units
The potential Hardware 4.5 sighting was first reported by Model Y owner @Eric5un, who shared details of a Fremont-built 2026 Model Y AWD Premium delivered this January. As per the Model Y owner, the vehicle includes a new front camera housing and a 16-inch center display, along with an Autopilot computer labeled “AP45” and part number 2261336-02-A.
The Tesla owner later explained that he confirmed the part number by briefly pulling down the upper carpet liner below the Model Y’s glovebox. Other owners soon reported similar findings. One Model Y Performance owner noted that their December build also appeared to include Hardware 4.5, while another owner of an Austin-built Model Y Performance reported spotting the same “AP45” hardware.
These sightings suggest that Tesla may already be installing revised FSD computers in its new Model Y batches, despite the company not yet making any formal announcements about Hardware 4.5.
What Hardware 4.5 could represent
Clues about Hardware 4.5 have surfaced previously in Tesla’s Electronic Parts Catalog. As reported by NotATeslaApp, the catalog has listed a component described as “CAR COMPUTER – LEFT HAND DRIVE – PROVISIONED – HARDWARE 4.5.” The component, which features the part number 2261336-S2-A, is priced at $2,300.00.
Longtime Tesla hacker @greentheonly has noted that Tesla software has contained references to a possible three-SoC architecture for some time. Previous generations of Tesla’s FSD computer, including Hardware 3 and Hardware 4, use a dual-SoC design for redundancy. A three-SoC layout could allow for higher inference throughput and improved fault tolerance.
Such an architecture could also serve as a bridge to AI5, Tesla’s next-generation autonomy chip expected to enter production later in 2026. As Tesla’s neural networks grow larger and more computationally demanding, Hardware 4.5 may provide additional headroom for vehicles built before AI5 becomes widely available.
