Tesla patent addresses panel gaps using clever clamping assembly
The build quality of Tesla’s vehicles would likely see a notable improvement in the near future. As revealed in a recently published patent, the company is working on a new type of clamping assembly that allows some flexibility between panels during manufacturing. With such a system in place, gaps between a vehicle’s panels could be adjusted and aligned during the assembly process.
Tesla’s newly published patent, titled “Clamping Assembly for Securing Together a Pair of Adjacently Located Panels,” describes a simple yet clever way to address misaligned body panels. Tesla notes that conventional clamps, which are usually utilized to attach body panels to a vehicle’s frame, are unable to connect panels and their individual tolerances effectively due to their rigid structure.
“Although (conventional clamps) can be used to secure adjacently located parts to one another, the clamp does not account for parts that have large manufacturing tolerances or parts that must not be fixed in at least one direction (that is there must be play between the parts). Attempting to use a traditional clamp to secure two parts that must have some play between them may introduce unsightly gaps and/or overlaps between the parts, reducing the aesthetic appearance upon assembly.”

Tesla’s patent outlines a new type of clamping assembly that is more flexible. Such a system enables Tesla to adjust panels during assembly, allowing the company to address any possible misaligned panels before the vehicle is sent off to delivery. Tesla explains the rationale of its new clamp as follows.
“The present invention was derived in light of the foregoing challenges, and it is an object of the present invention to provide a clamping assembly that provides flexibility in securing parts that are manufactured to larger dimensional tolerances and in which play is necessary between adjacent parts during, or after, assembly. The clamping assembly of the present invention can accommodate misalignment of the part or parts owing to variances in one or both parts during manufacture and/or necessary play between the parts by allowing flexibility in adjusting the positions of the parts relative to one another in one direction while still securing the parts to one another. That is, the clamping assembly secures together a pair of manufactured parts, in which the manufactured parts require play along at least one direction while confining the movement of the parts in a second direction.
“According to certain embodiments of the present invention, the clamping assembly includes a retainer member. The retainer member may have a U-shape groove that allows for the insertion of a tab member and a narrow retaining throat that confines a bulbous portion of the tab member in multiple directions. For example, once inserted into the groove of the retainer member, the tab member with the bulbous portion is confined from moving vertically and horizontally. Once inserted into the groove of the retainer member, movement of the tab member with the bulbous portion is possible by sliding the tab member and the bulbous portion thereof relative to a plane P 2 of the groove, i.e., by sliding the tab member and the bulbous portion into or out of the page. Thus, with use of the clamping assembly disclosed herein, some play or flexibility between two panels is possible, and the panels can be adjusted relative to one another during assembly.”

Tesla has been challenged with misaligned panels on its vehicles in the past. When Detroit’s Sandy Munro started his teardown of an early production Model 3, for one, the auto veteran lamented that the vehicle’s panel gaps were so inconsistent, they were reminiscent of a Kia from the 90s. Munro was eventually blown away by the Model 3’s battery, tech, ride quality, and performance, but his criticism of the car’s build quality were notable until he completed his analysis. Tesla later issued a response to Munro’s criticism of the early production Model 3’s build quality, stating that “the standard deviation of all gaps and offsets across the entire car has improved, on average, by nearly 40%, with particular gap improvements visible in the area of the trunk, rear lamps and rear quarter panel.”
A letter to Tesla employees sent last April revealed that Elon Musk is taking the issue of misaligned panels very seriously. In his message, Musk noted that while the build quality of the company’s vehicles continues to improve, Tesla must strive to push harder in ensuring that its electric cars have design tolerances that are a factor of ten better than any other vehicle in the auto industry.
“Most of the design tolerances of the Model 3 are already better than any other car in the world. Soon, they will all be better. This is not enough. We will keep going until the Model 3 build precision is a factor of ten better than any other car in the world. I am not kidding. Our car needs to be designed and built with such accuracy and precision that, if an owner measures dimensions, panel gaps, and flushness, and their measurements don’t match the Model 3 specs, it just means that their measuring tape is wrong,” Musk wrote.
There is no denying that misaligned panels are an issue for Tesla’s electric cars, particularly early production models produced in the past. In a way, such issues are part of Tesla’s growing pains, considering that mastering panel alignment is among the more basic aspects of vehicle manufacturing. That said, Elon Musk’s unrelenting stance on improving build quality, together with clever ways to address and avoid misaligned panels, might soon allow the company to shake off its panel gap issues altogether.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion
The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.
The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.
But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:
🚨 Tesla Cybercab charging port is in the rear of the vehicle!
Here’s a great look at plugging it in!!

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.
However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.
Wireless for Operation, Wired for Downtime
It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.
The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.
Tesla wireless charging patent revealed ahead of Robotaxi unveiling event
However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.
In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.
Induction Charging Challenges
Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.
While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.
Production Timing and Potential Challenges
With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.
It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.
In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
