Tesla Semi truck production would showcase lessons gained from Model 3
Being the electric car maker’s first entry into the trucking industry, the stakes are high for the Tesla Semi. Just like the Model 3, Tesla could revolutionize the trucking industry if the Semi proves to be a success. The company is aiming to start production of the Semi sometime in 2019 — a target that exhibits Elon Musk’s tendency to adopt aggressive manufacturing timelines. That said, if Tesla’s progress in the Model 3 ramp is any indication, there is a good chance that the Semi could be Tesla’s first vehicle to not run into major problems when it starts production.
Tesla is no stranger to missed production deadlines. In 2007, Tesla announced that it has plans to build 10,000 of the then-mythical Model S sedan annually starting in 2009. Production was ultimately delayed, and the vehicle was introduced in June 2012. The Model X experienced an even more significant delay, with deliveries starting on September 2015 instead of its initially planned early 2014 release. Tesla’s latest vehicle, the Model 3, has experienced delays as well — an ordeal that CEO Elon Musk aptly dubbed as “production hell.” When the handover of the first 30 Model 3 was held last year, Musk announced that Tesla is aiming to produce 5,000 units of the electric sedan a week by the end of 2017. Tesla was only able to hit that target at the end of Q2 2018.
Considering Tesla’s history and reputation for delays, does this mean that the Semi would follow the same fate? Most likely not. On the contrary, the Semi might very well be the first Tesla vehicle that would not experience a delay as bad as its predecessors. Tesla might miss its 2019 target for the truck given that the timeline was announced by a very optimistic Elon Musk, but once manufacturing begins, there is a good possibility that the Semi would not take the company to “production hell” like the Model 3.
When Elon Musk unveiled the Semi last November, he pitched the vehicle as an electric truck that can disrupt the trucking industry. With stunning performance specs such as a 0-60 mph time in 5 seconds flat, a capability to haul 80,000 lbs of cargo, and a range of 500 miles per charge for the Long Range version, the Semi is a serious long-hauler. These impressive specs aside, one thing that made the Semi quite remarkable was the fact that it shared components with the Model 3, from its four electric motors to the two touchscreens on the driver’s console. A video of the Semi shared earlier this year on YouTube even showcased how the truck features an air vent similar to the Model 3.
Tesla is not done with the Semi either. As testing of the vehicle continues, Tesla is rolling out improvements to the truck’s design. Back in May, Elon Musk stated that the Semi’s range would be closer to 600 miles per charge. During the Q2 earnings call, Elon Musk also teased a new battery module “that’s actually lighter, better, (and) cheaper.” These new modules are expected to start production sometime in Q1 2019, which could result in vehicles being lighter and having more range — advantages that are pertinent for the electric long-hauler.
Tesla’s production ramp for the Model 3 proved to be a classic tale of trial and error, with a dash of automation-driven hubris thrown in. Over the past year, the company learned a lot of lessons as it evolved from an upstart automaker into a more mature car company. When Tesla starts the Semi’s production, there’s a good chance that it would no longer be a company that adopts unrealistic release timelines. Instead, it would be an automaker that has gained experience over years of missed deadlines. The fact that the Semi shares components with the electric sedan would be a given plus, but the real boost in the manufacturing of the electric truck would likely be caused the expertise that Tesla gained when it tackled the challenge of the Model 3 ramp.
The market for the Tesla Semi is vast, and so far, reactions from the market are encouraging. During the company’s Q1 2018 earnings call, Elon Musk and CTO JB Straubel noted that Tesla has around 2,000 reservations for the vehicle. Tesla has also acquired orders from companies such as PepsiCo, FedEx, and UPS in the United States and Bee’ah from the United Arab Emirates, to name a few.

Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
Tesla set to launch “Terafab Project: A vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla is making one of the boldest bets in its history. On March 14, Elon Musk posted on X that the “Terafab Project launches in 7 days,” pointing to March 21, 2026 as the start date for what he has described as a vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla first confirmed Terafab on its January 28, 2026 earnings call, where Musk told investors the company needs to build a chip fabrication facility to avoid a supply constraint projected to materialize within three to four years. But the seeds were planted even earlier. At Tesla’s annual general meeting last year, Musk warned that even in the best-case scenario for chip production from their suppliers, it still wouldn’t be enough, and declared that building a “gigantic chip fab” simply had to be done.
While there has been no official announcement on where Tesla plans to break ground on the massive Terafab, all signs point to the North Campus of Giga Texas in Austin.
Months of speculation has surrounded Tesla’s North Campus expansion at Giga Texas, where drone footage captured by observer Joe Tegtmeyer revealed massive construction site preparation just north of the existing factory on a scale that rivals the original Giga Texas footprint itself.
Samsung’s Tesla AI5/AI6 chip factory to start key equipment tests in March: report
The project is projected to produce 100–200 billion AI and memory chips annually, targeting 100,000 wafer starts per month, at an estimated cost of $20 billion. Tesla is targeting 2-nanometre process technology and anticipated to be the most advanced node currently in commercial production. Dubbed the Tesla AI5 chip, the chip will pack 40x–50x more compute performance and 9x more memory than AI4, and will be among the first products Terafab factory is set to produce. This highly optimized, and massively powerful inference chip is designed to make full self-driving (FSD) and Tesla’s Optimus robots faster, safer, and with full autonomy.
This is where Terafab becomes a genuine game-changer. If Tesla successfully builds a 2nm chip fab at scale, it becomes one of only a handful of entities that’s capable of producing AI silicon in-house, with competitive implications that extend far beyond Tesla’s own vehicles, and potentially positioning Tesla as a chip supplier or licensor to other industries.

The next-gen Tesla AI chips will power advancements in Full Self-Driving software, the Cybercab Robotaxi program, and the Optimus humanoid robot line. Musk’s projections for Optimus require chip volumes that no existing external supplier can commit to on Tesla’s timeline.Competitors like Waymo and GM’s Cruise remain dependent on third-party silicon, leaving them exposed to the same supply chain vulnerabilities Tesla is now working to eliminate entirely.
The Terafab launch this week may not mean a factory opens its doors overnight, but it signals Tesla is serious about owning the entire AI stack, from software to silicon.

What is Digital Optimus? The new Tesla and xAI project explained
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.
This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.
Grok is the master conductor/navigator with deep understanding of the world to direct digital Optimus, which is processing and actioning the past 5 secs of…
— Elon Musk (@elonmusk) March 11, 2026
Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.
xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.
When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.
Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.
Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.
It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.
Oh and it works in all AI4-equipped cars, so your car can do office work for you when not driving.
We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power.
— Elon Musk (@elonmusk) March 12, 2026
Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.
By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.
As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.
In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.
It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.
There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.
This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.
Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.
Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.
We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.
