The Boring Company’s innovations take center stage at Hawthorne test tunnel opening event
Two years ago, Elon Musk founded a tunneling startup aimed at battling what he creatively described as “soul-destroying traffic.” Musk’s idea was simple — traffic congestion can be addressed by using underground tunnels where vehicles can travel at extremely fast speeds on electric skates. Hence, a startup aptly named The Boring Company was born.
Since then, the tunneling company has acquired a high-profile project in Chicago, developed low-cost bricks from tunneling rocks, and completed its first test tunnel. Constructed on the backyard of the SpaceX headquarters, the Boring Company’s Hawthorne test tunnel was unveiled on Tuesday in an opening party, complete with entertainment, fun activities, and a medieval watchtower overlaid with Boring Bricks.
Being smaller in diameter than traditional tunnels, The Boring Company’s projects are more cost-effective and faster to construct. Its 1.14-mile Hawthorne tunnel, for example only cost ~$10 million to build, including internal infrastructure, lighting, comms/video, safety systems, ventilation, and tracks. Conventional tunneling projects, which involve larger tunnels and traditional digging methods, could cost as much as $1 billion per mile.
Elon Musk conducted an information session to members of the press prior to the official start of the unveiling. During the meeting, Musk discussed some updates about the startup’s concepts. For one, Musk noted that The Boring Company had changed its idea of using electric skates to propel cars. Instead of using pre-made electric skates, the company is now using the vehicle as the skate itself.
“There won’t be a skate — no more skate. The vehicle is the skate,” Musk said.

The Hawthorne test tunnel would be utilizing the Loop System, which is designed to accommodate cars and passenger pods. During the Q&A, Musk noted that the Loop is a step towards the eventual creation of Hyperloop, which utilizes pods traveling inside low-pressure tubes at speeds of up to 700 mph. “The loop is a stepping stone toward Hyperloop. Loop is for transport within a city. And Hyperloop is transport between cities,” Musk said.
Apart from referencing Hyperloop transportation, Musk further discussed other possible uses for The Boring Company’s technology. Reiterating an idea he expressed during a “fireside chat” in Los Angeles with LA Mayor Eric Garcetti, Musk noted that the Boring Co.’s tunnels could also be used for utilities such as water lines. Due to the tunnels’ construction and design, Musk stated that “If a water main breaks, it floods through the tunnel one end, and gets pumped out the other.” This would allow cities to address utility issues without much hassle.
Just like Musk’s other companies like Tesla and SpaceX, The Boring Company is in a constant process of innovation. The startup, for one, continues to design and develop its third-generation Tunnel Boring Machine. Once operational, the new TBM would be capable of digging 15 times faster than a conventional boring machine. Apart from using a fully-electric system to increase power, The Boring Machine is also designing the upcoming TBM’s cutter head to process more dirt. In yet another step away from convention, the tunneling startup is also creating reinforcement segments on site using the dirt excavated from the tunnel itself.
Musk has noted that The Boring Company’s tunneling projects are already attracting a lot of interest, stating that “we have more demand on tunnels than we can satisfy,” and that “we have people hounding us to invest nonstop.” In a flourish of classic Elon Musk humor, the Tesla and SpaceX CEO noted that “it’s kinda ridiculous how much interest we’ve had in investing in Boring Company.” Elaborating further, Steve Davis, the CEO of the Boring Company, added that the startup receives “greater than 5 and less than 20 requests per week from different municipalities and stakeholders.”
Tesla is using the vehicles’ internal microphones to improve build quality, Vice President of Engineering Lars Moravy revealed recently.
It’s no secret that Tesla is always finding ways to make its manufacturing operations more efficient, accurate, and valuable. Constantly trying to make its cars better, the company has never placed any restrictions on what it will do to improve everything from panel gaps to paint.
As Teslas have been driving autonomously on the property of the Gigafactory Texas plant for a while now, Moravy revealed to Herbert Ong in a new interview that cars rolling off production lines now autonomously navigate themselves through a bumps, squeaks, and rattles (BSR) portion of the line. This helps to identify any loose or improperly installed internal parts.
The cabin’s microphones, which are used for a variety of things in ownership, simultaneously monitor any noises inside the vehicle while it rolls through the BSR portion of the production line. Moravy actually revealed that Tesla is trying to build “Full Self-Hearing,” an AI system that will detect minor imperfections so they can be corrected before delivery.
It’s no secret that build quality is something that Tesla struggled with as it scaled to a fully massive production operation that manufactures over 1.6 million vehicles per year. However, in recent years, especially, there have not been as many complaints. Tesla has truly improved upon its build quality and paint quality over the past several years, especially in the U.S.
Tesla’s ‘megacasts’ are key to massive build quality improvements
While those improvements have been evident, there are still some complaints; no automaker is perfect with this. But this step will now ensure that every single car that rolls off the production lines at Gigafactory Texas will be void of any creaks, squeaks, or squeals when it leaves the factory.
This measure is one of the most unique we’ve seen in terms of a strategy to avoid build quality issues, but it is not exclusive to Tesla.
Ford uses acoustic analysis AI to find abnormalities in seat motors, climate control units, and other components. Suppliers and OEMs will also use microphone arrays or particle velocity sensors in end-of-line stations.

Tesla crushes Wall Street expectations, beats delivery estimates by over 15 percent
Tesla (NASDAQ: TSLA) beat Wall Street expectations of 406,000 vehicles delivered in Q2 by reporting 480,126 deliveries for the three months ending in June.
Tesla reported it delivered 467,762 Model 3 and Model Y units, while 12,364 Model S, Model X, and Cybertrucks switched hands during the quarter. The Model S and Model X were officially sunset this past quarter and will no longer be part of the company’s Production & Delivery reports moving forward.
🚨 BREAKING: Tesla delivered 480,126 vehicles in Q2, ANNIHILATING Wall Street expectations of 406,000. Production was reported at 451,758.
Deliveries:
Model 3/Y: 467,762
Other Models: 12,364Production:
Model 3/Y: 442,936
Other Models: 8,822 https://t.co/TTHwQAsKt8 pic.twitter.com/7qI4Zj6FE5— TESLARATI (@Teslarati) July 2, 2026
The quarter is a pleasant surprise and a good rebound from Q1, when Tesla slightly missed the Wall Street consensus of 365,645 cars by reporting 358,023 deliveries for the first three motnhs of the year.
Energy storage deployments also provided some strength in Tesla’s delivery report, hitting 13.5 GWh for Q2. This is a particular division of Tesla’s business that has been overwhelmingly robust over the past few years, truly being a strong point of the company’s overall model.
For the year, Tesla analysts still predict deliveries to trend in the 1.69 million unit region, a modest 3 to 5 percent increase from the 1.64 million cars the company delivered last year. Tesla will likely return to more sequential and noticeable year-over-year growth as the Cybercab project starts to ramp up considerably in the next few years.
Tesla has some other potential catalysts to spur vehicle deliveries, too. Not only is it expecting Cybercab to truly start making a change in the next few years, but other vehicles could be entering the company’s lineup.
Tesla sends production Cybercab with no steering wheel, pedals to on-road testing
The slightly longer Model Y L has been a highly speculated release candidate in the U.S. It has already done incredibly well in China, and U.S. buyers have been wanting slightly more interior space than the Model Y. Now that the Model X is gone, it is more needed than ever.
Q2 highlights a pretty stable automotive division within Tesla, and no true concerns arise from these figures, especially considering it managed to beat expectations convincingly.
Tesla CEO Elon Musk posted a photo of himself standing with the Optimus production team inside Tesla’s Fremont factory, arms crossed amid workers in hard hats and safety vests. The image captures a pivotal industrial shift: the same facility space once dedicated to building Tesla’s flagship Model S sedan and Model X SUV is now home to the company’s humanoid robot manufacturing line.

Tesla’s Fremont Factory, acquired in 2010 from the former NUMMI joint venture between Toyota and GM, has been the company’s original U.S. manufacturing hub since Model S production began in 2012.
The Model X followed soon thereafter. These premium vehicles offered lower annual volumes, recently around 30,000 combined, compared to the high-volume Model 3 and Model Y lines that continue around the site. Over their combined run, the S and X accounted for roughly 610,000 units.
In late January 2026, during Tesla’s Q4 2025 earnings call, Elon Musk announced the end of Model S and Model X production in Q2 2026. The final vehicles rolled off the line in early May. Rather than retooling for another vehicle, Tesla chose to convert the dedicated S/X assembly area into a dedicated Optimus Gen 3 production line.
Model 3 and Y manufacturing remains unaffected. Tesla’s official Fremont Factory page now lists Optimus alongside the 3 and Y as core products.
The conversion was executed with remarkable speed. After production stopped, crews dismantled the existing vehicle line and installed entirely new modular equipment—including lines sourced from Germany and dozens of sub-lines for actuators, batteries, and other components—in roughly four months.
Musk described the timeline as “insanely fast,” noting it would be unprecedented for any other manufacturer. Initial Optimus output is expected to ramp slowly due to the robot’s roughly 10,000 unique parts and the brand-new production processes involved. The Fremont line targets an eventual capacity of 1 million Optimus units per year.
Tesla isn’t joking about building Optimus at an industrial scale: Here we go
Optimus Development Timeline
- August 19, 2021: Optimus (then called Tesla Bot) formally announced at Tesla’s first AI Day. A concept video showed a person in a suit demonstrating the vision for a general-purpose humanoid capable of dangerous, repetitive, or boring tasks using the same AI architecture as Full Self-Driving.
- 2022: Early prototypes displayed. At the second AI Day in September, semi-functional units demonstrated walking across a stage and basic arm movements
- 2023: September videos showed improved capabilities, including sorting colored blocks, precise limb awareness, and holding a Yoda pose.
- 2024-early 2025: Factory integration videos showed Optimus navigating workspaces and handling objects like battery cells.
- January 2026: Gen 3 mass-production activities began at Fremont, with reports of over 1,000 Gen 3 units already operating inside the factory for real-world learning and AI training
- April 2026: Musk confirms Optimus production on converted Fremont line would begin in late July or August 2026. The Gen 3 reveal, originally eyed for Q1, was pushed closer to production start. A second, much larger Optimus factory at Giga Texas is under construction, with volume production targeted for Summer 2027 and long-term capacity of 10 million units annually
- July 1, 2026: Musk’s on-site visit and team photo confirm the Optimus line is operational and the transition is actively progressing
Tesla positions Optimus as potentially its largest project ever, leveraging vertical integration, AI expertise, and car-like manufacturing know-how to scale humanoid robots first for its own factories and later for broader industrial and consumer use.
The Fremont conversion serves as a critical proving ground for this ambitious new chapter in Tesla’s already-rich history.
