Tesla Lead Engineer urges Rivian to optimize R2 for existing Supercharger Network
The Rivian R2 has received much acclaim from the electric vehicle community, and this is highlighted by CEO RJ Scaringe’s announcement stating that the company had received over 68,000 reservations for the upcoming all-electric crossover SUV. But while the Rivian R2 has earned praise for its price, specs, and looks, one aspect of the vehicle has raised eyebrows — its charge port location.
As could be seen in the Rivian R2 prototype that was shown off onstage, as well as the R3 and R3X prototypes that were unveiled after, the electric vehicle maker has opted to equip its upcoming vehicles with a charge port located on the rear passenger side. This, as noted by EV owners, would result in the R2 taking up two spots at Tesla’s V3 and V2 Superchargers.
EV advocate Chris Hilbert, who attended the R2 event, claimed in a post on X that Rivian was able to provide him an answer behind the R2’s charge port location. As per Hilbert, “Rivian is counting on the charging infrastructure to adapt over the next two years. Tesla should not dictate the port location. They are expecting (the) charge port location to not matter by 2026. They are also expecting the future to be curbside charging,” Hilbert wrote, though he also noted that Rivian employees were receptive when he told them that the R2’s charge port location was the vehicle’s only flaw.
I stopped back at the theater to talk to many @Rivian employees tonight. I told them this is the only flaw of the vehicle and they were wrong on charge port location. They did listen to the feedback. They have 2 years to fix it. https://t.co/d9mTqhBFWs— Chris Hilbert (@Hilbe) March 8, 2024
The Rivian R2’s charge port location has since become a well-discussed topic in social media. On Friday morning, Tesla Cybertruck Lead Engineer Wes Morrill weighed in on the matter, encouraging Rivian to move the charge port of the R2 to the rear driver’s side instead. While the Tesla Lead Engineer admitted that Tesla’s V4 Superchargers have longer cables that could accommodate electric vehicle charge port doors in any location, Tesla’s existing network of V3 and V2 Superchargers — which number over 50,000 — are optimized for vehicles whose charge port doors are located in the rear driver’s side.
“RJ Scaringe and Nick Kalayjian, cool product. Great looking prototypes. I know how these things go. There is still time to move the charge port location. It will take some re-engineering but the tools are not kicked off yet. This location will forever doom all Rivian owners to be the jerk taking two spots at a Tesla charger. Don’t do that to your customers.

“I know the Rivian Network has been installed to support the front left/rear right, but there are <500 Adventure Network fast charge handles vs more than 50,000 Supercharger handles. You’ve done the right thing for customers moving to NACS. Take it the last mile and put it in a location that works seamlessly with existing infrastructure. Can be the front right if you are trying to optimize for street parking. Looking forward to charging harmoniously with a great-looking EV,” Morrill wrote in a post on X.
Rivian has highlighted that it puts consumers’ feedback front and center when it designs its vehicles. Considering the substantial requests from EV community members calling for Rivian to move the location of the R2’s charge port door, it would truly be surprising if the electric vehicle maker stands firm and still releases the upcoming all-electric crossover SUV with its original charge port location.

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.
