Tesla Semi cabin’s Model 3-inspired elements showcased in new video
A video featuring a rare look at the Tesla Semi’s cabin was recently uploaded on YouTube. As could be seen in the short clip, the all-electric long-hauler features some compelling design elements, from components inspired by the Model 3 to a mysterious pedal beside the vehicle’s brakes.
The Semi’s recent video was uploaded by Moldova-born YouTuber and truck enthusiast Andrew Black, who was able to get up close and personal with the all-electric long-hauler. The Tesla Semi in the video was hauling a trailer from Xtra Lease Trailers, suggesting that the truck was in a transport run when the footage was taken.
Immediately noticeable from the Tesla Semi’s cabin was how roomy and spacious it was. Even with the jumpseat for the passenger unfolded, the electric truck still has a very roomy feel. Upfront, several design elements pop up, the most notable of which is an air vent inspired by the Model 3. The Tesla Semi also features a clean, minimalistic, end-to-end dashboard that runs from one side of the vehicle to the other.
In a lot of ways, the Tesla Semi actually borrows some components from the Model 3. Apart from its end-to-end HVAC system, the Semi also uses the same electric motor as the compact electric car (it has four Model 3-derived electric motors). The Semi is fitted with what appears to be the door handles of the Model 3, as well as dual touchscreen controls that invoke the compact electric car’s landscape-oriented center touchscreen. The size of the Semi’s two touch panels have not been mentioned by Tesla, but based on Black’s recent video, it seems safe to assume that its dual displays are also 15-inch panels.
One thing that grabs the attention from the video, however, was a rather mysterious pedal that could be seen near the 1-minute mark. As the camera was being panned across the Tesla Semi’s cabin, the all-electric truck’s accelerator and brake pedals could be seen prominently. To the left of the brakes, however, was seemingly another pedal. Unlike the dead pedal found in the Model S, Model X, and Model 3, the third pedal in the Semi was rather small, and it looked functional. Some members of the r/TeslaMotors subreddit have weighed in on the mysterious pedal, with a number suggesting that it could be a mechanical parking brake.

Just like the Model 3, the Tesla Semi has the potential to be an incredibly disruptive vehicle. The electric truck is a Class 8 truck equipped with four Model 3-derived electric motors, which enable it to accelerate from 0-60 mph in 5 seconds flat without cargo. With a full 80,000-lb load, the Semi is still capable of hitting highway speed in 20 seconds, far quicker than comparable diesel-powered semi-trailers.
The Tesla Semi is currently being tested and driven across the United States. Just recently, the electric long-hauler was spotted driving over the Golden Gate Bridge on its way to Santa Rosa, CA. According to Tesla’s Tesla’s VP of Truck Programs Jerome Guillen in his LinkedIn profile, the Semi was headed to Santa Rosa to visit some local customers.
Tesla CEO Elon Musk and CTO JB Straubel revealed during the Q1 2018 earnings call that the Semi currently has around 2,000 reservations from businesses within and outside the United States. In the United States alone, several high-profile companies have already placed orders for the electric truck, including PepsiCo, FedEx, and Anheuser-Busch. Outside the United States, grocery chain ASKO from Norway has placed reservations for the long-hauler, as well as waste management conglomerate Bee’ah from the Middle East, among others.

Tesla shared a striking video showcasing the decommissioning of the original Model S and Model X assembly line at its Fremont Factory in Northern California. Completed in just 46 days, the teardown involved heavy machinery dismantling concrete pits, removing robotic arms and conveyors, and clearing the space for new production.
The post, captioned “End of an era,” captured both the end of a historic chapter and Tesla’s aggressive pivot toward its next major initiative, Optimus.

The decision to retire the Model S and Model X originated during Tesla’s Q4 2025 Earnings Call in late January 2026. CEO Elon Musk announced that production of the company’s flagship sedan and SUV would wind down by the end of Q2 2026, describing it as bringing the programs to an “honorable discharge.”
Custom orders ceased around early April 2026, with the final vehicles rolling off the line in early May. A special signature delivery ceremony on May 20 marked the emotional close for these vehicles, which had defined Tesla’s early success and luxury EV segment since the Model S launch in 2012.
The primary reason for tearing down the lines was to repurpose the valuable factory floor space for high-volume production of Tesla’s Optimus humanoid robot. Musk had indicated on Earnings Calls that the Fremont S/X line would be replaced by a dedicated Optimus manufacturing line targeting a capacity of one million units per year.
This move aligns with Tesla’s broader strategic shift from traditional vehicle manufacturing toward robotics and artificial intelligence, leveraging the company’s expertise in autonomy, AI training, and high-volume production.
Optimus, Tesla’s general-purpose humanoid robot, is designed to perform repetitive or dangerous tasks in factories, warehouses, and eventually homes. Powered by Tesla’s AI and Neural Networks, it aims to be a versatile, affordable platform. Production of Optimus Gen 3 is already underway in limited form at Fremont, with full-scale output on the converted line expected to begin in late July or August.
Tesla is targeting rapid scaling, with internal ambitions pointing toward tens or even hundreds of thousands of units annually by the end of 2026.
Longer-term, Tesla is constructing a much larger second-generation Optimus facility at Giga Texas, with potential capacity reaching millions of units per year. The company views Optimus as a transformative product that could eventually surpass its automotive business in scale and value, enabling widespread deployment of useful robots across industries. CEO Elon Musk has even predicted it would be the most popular product of all-time.
As one era closes at Fremont, another is rapidly taking shape.
Elon Musk posted a candid admission on his social media platform X on June 9, declaring that he had been “clearly wrong” about Anthropic. The statement marked a notable reversal from his earlier skepticism toward the AI company.
In September, Musk had written, “Winning was never in the set of possible outcomes for Anthropic,” reflecting his view at the time that the startup had lacked the foundation or even the trajectory to succeed in what is an incredibly intense race for advanced artificial intelligence.
Musk’s latest post came amid discussion of Anthropic’s reliance on external compute resources. He praised the company’s progress, stating that Anthropic is “obviously currently the leader in AI” and that “no company has released a model as good as Mythos/Fable,” with expectations of a strong follow-up in Mythos 2.
The tone shifted dramatically from dismissal to acknowledgement of superior performance.
I was clearly wrong about Anthropic. They are obviously currently the leader in AI. No company has released a model as good as Mythos/Fable and they will undoubtedly have Mythos 2 ready soon.
And I would never cut them off in a way that hurt them badly, even as a competitor.…

The context of Musk’s comments added significance. Anthropic has been operating under a recent compute deal with SpaceXAI, Musk’s AI infrastructure-focused venture. The pair entered a short-term GPU lease agreement initiated in May, providing Anthropic access to critical computing power for training and deploying its frontier models.

Some observers had speculated that Musk could leverage this dependency to disadvantage a rival. Musk directly addressed the possibility, writing, “I would never cut them off in a way that hurt them badly, even as a competitor. That’s not my style.”
To support his commitment to ethical competition, Musk referenced concrete examples from his other companies. Tesla famously open-sourced its entire portfolio of electric vehicle patents in 2014. The move was designed to accelerate the global adoption of sustainable transportation technology rather than protect proprietary advantages.
Tesla also made its Supercharger network available to competing electric vehicle manufacturers, transforming what could have remained an exclusive charging ecosystem into a shared infrastructure that benefits the broader industry and reduces barriers for EV adoption.
Musk further pointed to SpaceX’s practices, noting that the company launches satellites for competing commercial systems “with no increase in price or use of unfair terms.” He extended the principle to his social platform, observing that “even my worst enemies attack me on this platform,” underscoring preference for open discourse over retaliation.
These examples have illustrated Musk’s long-standing philosophy that long-term technological progress is best served by open competition and infrastructure sharing rather than leveraging market power to stifle rivals. In the fast-evolving AI sector, where compute resources and model capabilities determine leadership, Musk’s stance suggests a willingness to compete on innovation and performance alone.
Musk’s admission arrives as SpaceXAI itself advances its own frontier models while maintaining business relationships across the ecosystem. By publicly correcting his earlier assessment and reaffirming principles of fair play, Musk highlights a model of competition that prioritizes advancement of the field over short-term tactical advantages.
A Tesla analyst believes the company’s Full Self-Driving suite is close to an “inflection point,” where people will finally realize that it is more than what it appears, similar to how many view the iPhone.
Pierre Ferragu, an analyst who has covered Tesla for many years at New Street Research, says the Full Self-Driving suite is one piece of evidence supporting the view that a Tesla is more than a car. He compared it to the iPhone and noted that the high price tag seemed like a lot for a phone early on. Then people realized the iPhone was more than just something you make calls with. It made their lives simpler.
🚨 Analyst @p_ferragu says Tesla Full Self-Driving is at an “inflection point” in a recent commentary:
“A Tesla is not a car, the same way an iPhone was not a phone. As a tool that gets you to work peacefully every morning, it is not expensive. Give us 2 more quarters to see… pic.twitter.com/tm6xFrjVPV

Suddenly, that price tag was justified.
Tesla offers several models under the average transaction price for a new vehicle, which was above $49,000, according to Kelley Blue Book. However, that does not take into account that many people can still not afford a $35,000 vehicle. Ferragu offers his thoughts:
“Remember when the addressable market of the iPhone was 10 million units? Then people realized how good it was, and now, nearly 250m are sold every year.
A similar evolution for Tesla is still on the table. A Tesla is not a car, the same way an iPhone was not a phone.
A model 3 at $35k + $100 per month is too expensive for most, but only as a car, the same way a $600 iPhone was too expensive for most, until most realized it was much more than a phone.
As a tool that gets you to work peacefully every morning, it is not expensive.”
This point is valid, especially considering the iPhone’s impact on the cell phone market. There are still a handful of players, but most people you know have an iPhone. The iPhone ties into Apple’s other ecosystem of products.
This is how Tesla plans to infiltrate the automotive market, and once the company offers a fully autonomous suite, or something that can allow for unsupervised self-driving, more and more people will flock to Tesla.
Ferragu believes Tesla needs two additional quarters of development before things will truly change. He didn’t elaborate on what will happen in two quarters, but he said it will give us all time to “see where this is heading.”
It is really quite interesting to see people’s reactions when they find out what a Tesla is capable of. Full Self-Driving is a great tool for taking stress out of travel; I use it daily, and it has made it really difficult to consider taking any other car on a drive of practically any length.
To me, it is really hard to believe that people will not at least seriously consider a Tesla as their next car if they experience Full Self-Driving. This is a major point for those who argue that Tesla should advertise in some way.
