Tesla's focus on batteries is being proven right, and other EV makers are paying the price
As more and more automakers begin the transition to electric vehicles, it is becoming increasingly apparent that Tesla’s intense focus on batteries was right all along. Tesla’s strategies have always been criticized and examined under a microscope, and the company’s decision to build Giga Nevada, a facility dedicated to battery production for the Model 3, was no exception. But as veteran automakers like Jaguar and Mercedes-Benz are now finding out, investing tons of effort and resources on batteries matters a lot.
Tesla is among the industry’s most vertically-integrated companies. Similar to Apple’s consumer electronics and SpaceX’s rockets, most of what goes inside a Tesla electric car is designed and built in-house. Tesla is so serious about this; the company actually made its own seats. The same is true for the electronics that goes inside every Tesla. They are so different and superior to off-the-shelf components that teardown expert Sandy Munro compared them to the electronics of a literal fighter jet.
A lot of Tesla’s resources are dedicated to its battery improvements. Teslas stand tall among their rivals in the EV marketplace today primarily due to their efficiency and range, and this is made possible by the company’s battery tech. The company is not showing any signs of stopping too. Tesla has acquired several companies that could further improve its batteries, such as Maxwell Technologies and Hibar Systems. The electric car maker is even looking to produce its own batteries, with reports indicating that work is already underway to develop custom cells for Tesla’s next generation of vehicles and products.
It’s a difficult pill to swallow, but veteran automakers have reached a point where they must honestly admit that when it comes to batteries, Tesla has a notable lead. The very representation for this idea is the Porsche Taycan, an otherwise excellent high-performance electric vehicle whose ~200-mile EPA range is an Achilles Heel. Porsche, similar to other EV makers, opted for off-the-shelf batteries for the Taycan, and it shows. The car performs beautifully, and it’s arguably the only EV that can beat a Model S fair and square in a race, but it simply does not have the range or the efficiency to beat Tesla’s flagship sedan on all metrics.
It’s not just about the battery tech and specific cell chemistries either. Over the years, Tesla also had the foresight to secure ample battery supply for its vehicles and products. From Panasonic, which has been Tesla’s partner since its early days, to CATL, which is the company’s partner for Giga Shanghai, the electric car maker has made careful preparations to ensure that its vehicles and products will always have enough batteries. Other EV makers are not as fortunate.
This is one of the reasons why the Jaguar I-PACE, one of the most decorated vehicles in modern auto history, actually stopped production for a week. Just like the Taycan, the I-PACE is actually a pretty decent EV, with its plush interior and aggressive exterior. But behind the I-PACE’s looks lies off-the-shelf batteries that are also used by other companies. This meant that when LG Chem could not supply enough cells for the vehicle, Jaguar had no choice but to stop the vehicle’s production temporarily.
The Mercedes-Benz EQC is in the same boat. Once deemed as a potential “Tesla Killer,” the EQC’s production target for 2020 was halved by the German automaker from 60,000 vehicles to just 30,000 units. The reason was something that is pretty familiar: Daimler just could not secure enough batteries. Even companies like Dyson and Aston Martin, both of which had plans to make EVs, eventually suspended their efforts to enter the electric car market.
Tesla is not a perfect company by any means. CEO Elon Musk would be the first to admit that the company has made many mistakes over the years. But for all its delays and production issues, there is very little that can be criticized about Tesla when it comes to its batteries and the company’s foresight in improving them and securing their supply for years to come.

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.
