The Tesla Semi’s recent Giga 1 sighting highlights its difference from other concept trucks
To say that the Tesla Semi ruffled some feathers when it was unveiled last year is an understatement. Prior to the reveal of all-electric truck, questions were abounding about its viability as an alternative to conventional diesel-powered long-haulers. Even after the Semi’s specs and performance were announced, the vehicle still attracted a lot of skepticism.
During an event for Daimler’s e-Actos electric truck, for example, the company’s Head of Trucks, Martin Daum, noted that Elon Musk’s claims about the Semi’s 300 and 500-mile range are farfetched. Citing limitations in battery tech, Daum stated that “If Tesla really delivers on this promise, we’ll obviously buy two trucks — one to take apart and one to test because if that happens, something has passed us by. But for now, the same laws of physics apply in Germany and in California.” Jon Mills, a spokesman for engine maker Cummins Inc. noted back in August that while electrification is in the future of the trucking industry, the vehicles are not viable in their current state.
Since it was unveiled, the Tesla Semi has been spotted traveling across the United States. Tesla unveiled two working prototypes of the Semi – one painted silver and the other matte black – when it unveiled the vehicle, and so far, both have been spotted testing on US roads. Both trucks were also sighted delivering cargo from Gigafactory 1 in NV to the Fremont factory in CA. Most recently, the silver Tesla Semi was sighted in Gigafactory 1, hauling a trailer and seemingly ready to transport cargo.
Tesla is not the only manufacturer coming up with a zero-emissions truck. As the transport industry starts accelerating its shift towards electrification, even prominent truck companies are coming up with their own green vehicles. Most of these vehicles exist as concepts for now, but they do give an idea of how veteran truckmakers are approaching the industry’s transition to the electric age.
Ford, for one, recently revealed the F-Vision concept, which is loaded to the teeth with cutting-edge tech, including an adaptable windshield that can lower and rise depending on the driver’s preference, as well as front lights that can be fully customized. Last month, Volvo introduced the Vera, its next-generation semi-trailer concept. Unlike Tesla and Ford’s truck, Volvo’s vehicle does not even have a driver’s cabin, as it is designed fully for autonomy. Startup trucking companies are also showcasing their offerings. Nikola Motors, for one, made headlines when it unveiled its long-range sleeper hydrogen-electric truck – the Nikola One – back in December 2016, and the company has since teased its next offering, a day cab called the Nikola Two.
There is little doubt that the upcoming electric truck concepts that have been unveiled so far are exciting vehicles in their own right. Inasmuch as this is the case, though, many of these impressive concepts feature technology that is still yet to be developed or refined. During the F-Vision’s unveiling, for one, Ford clarified that the truck is strictly a concept for now. Volvo’s Vera is a perfect fit for short-haul trips thanks to its 300 kWh battery that gives it a 187-mile range, but the vehicle can’t be deployed anytime soon since self-driving tech is still under development (even autonomous tech leader Waymo is reportedly struggling with its fleet’s real-world testing). Nikola’s hydrogen-electric trucks are powerful and boast long-range, but they would need a network of H2 refilling stations before they can be a viable alternative to diesel trucks. As a result, most zero-emissions truck concepts, including the Nikola One prototype, are yet to be sighted doing real-world tests on public roads.

This is where the Tesla Semi is different. Among the upcoming electric trucks in the market, the Semi is the one undergoing consistent, intensive real-world testing. The vehicle has been spotted in multiple states since its unveiling, at times even visiting the sites of reservation holders like UPS, J.B. Hunt and PepsiCo. As it conducts its extensive real-world tests, the vehicle undergoes a consistent process of improvement. This was highlighted by Tesla’s Head of Automotive Jerome Guillen during the Q2 2018 earnings call, when he stated that several improvements have already been introduced to the electric truck since it was unveiled last year. Elon Musk even teased on Twitter that the Semi would likely have closer to 600 miles of range per charge. With this, it seems safe to infer that the production version of the Tesla Semi would be better than the prototype that is currently traveling across the country today.
The Tesla Semi balances its features without overdoing it as well. It does not have the cloud-based autonomy of concepts like the Vera or the flashy variable front design of the Ford F-Vision, but ultimately, it does not need to have all these extra bells and whistles to become effective at what it’s designed to do. Tesla created the Semi to be a viable alternative to diesel-powered long-haulers, and if recent sightings and its consistent road tests is any indication, it appears that the vehicle is poised to be exactly that.
The Tesla Semi is expected to start production sometime in 2019. Recent reports have indicated that Tesla is planning on “earnestly” producing the Semi sometime in 2020.

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.
