Tesla Semi Unveiled: 500+ mile range, Bugatti-beating aero, 2019 production
Tesla CEO Elon Musk unveiled the company’s highly anticipated semi-truck Thursday night on an airport hangar adjoining the company’s Design Center in Hawthorne, CA. It’s the California-based electric car maker’s first foray into the commercial trucking industry.
Before a packed crowd of thousands, Musk revealed industry-disrupting details of the Tesla Semi.
The Tesla Semi can accelerate from 0-60 in 5 seconds, without cargo, and 20 seconds with a full 80,000 lb. load, more than twice as quick as a traditional diesel truck. The Semi can also traverse a 5% gradient at 65mph, compared to 45mph for diesel trucks. This is all powered by the truck’s four independent electric motors says Musk. “You can lose two of the four motors, and the truck will still keep going. In fact, even if you have only two of the four motors active it will still beat a diesel truck.”

In addition, the Tesla Semi has a .36 drag coefficient, compared to the standard of .65-.70. Musk compared it to a Bugatti, noting that the semi-truck beats the supercar’s .38 drag coefficient. “Overall, the Semi is more responsive, covers more miles than a diesel truck in the same amount of time, and more safely integrates with passenger car traffic,” says Tesla in its official announcement. The company also highlighted the fact that the Semi benefits tremendously from the regenerative braking that can recapture 98% of braking energy into the battery.
The Tesla Semi’s development has been led by Jerome Guillen, VP of Trucks and Programs. He has led the development of the truck since January 2016, and prior to his current role was VP of Worldwide Sales and Service and was the Model S’s Program Director & VP of Vehicle Engineering. While it may seem odd that Guillen jumped from Sales and Service to leading the development of an all-electric semi-truck, it’s worth noting that before joining Tesla, he was Director of Business Innovation at Daimler and General Manager of Freightliner (Large manufacturer of class 8 diesel semi-trucks, owned by Daimler).
Musk also pointed out that it takes 15 minutes for traditional diesel-powered semi-trucks to fuel up, where as a Tesla Semi can charge 400 miles in 30 minutes, which is provided by “Megachargers“. The Megachargers run on solar power and Tesla has guaranteed electricity rates of $0.07 per kWh with Semi owners.

The interior of the Tesla Semi has one seat positioned in the center and provides drivers with unparalleled visibility. The seat is surrounded by two touchscreens that reminisce the ones found in the Model 3 sedan. Tesla’s semi-truck will also be equipped with Enhanced Autopilot which Musk notes will provide safety by automatically pulling over and stopping when truckers are in danger.
The Semi also has a small front truck, “because why not”, said Musk. The glass windshield on the Semi is thermonuclear resistant glass, which Musk says is a big deal because semi-trucks often have their windshields crack twice a year (which renders the truck undrivable). It can be assumed that this incredible glass could be related to Tesla’s nearly indestructible Solar Roof glass development.
Tesla claims that the semi will cost 20% less per mile compared to diesel trucks, costing $1.26/mile versus $1.51/mile . But that wasn’t all. Musk announced convoy technology that will further reduce the cost per mile driven for the Tesla Semi, even beating the cost of rail-based transportation.
“Tesla Semi can also travel in a convoy, where one or several Semi trucks will be able to autonomously follow a lead Semi.”
While Tesla didn’t unveil the price of the Semi, Musk noted that the semi-truck is expected to save operators $200k on fuel alone over 1 million miles. This resonated with fleet owners as Jerome Guillen pointed to some important guests at the event, stating that they had “placed a lot of reservations”. First production of the Tesla Semi is expected sometime in 2019.

Tesla Optimus project fires up as Musk sees production line progress
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.

Tesla gets its latest short from Michael Burry: ‘Happy it jumped back to this level’
Tesla short seller Michael Burry, the subject of the film “The Big Short,” where he was portrayed by Steve Carell, has revealed he has opened a new bet against the stock.
In a new update to his Substack newsletter in a post titled “Trading Post June 30, 2026,” Burry revealed a new set of bets against Tesla, Caterpillar, NVIDIA, Applied Materials Inc., and the iShares Semiconductor ETF.
In regard to Tesla, Burry wrote:
“And finally I shorted Tesla at 416.22. Happy it jumped back to this level.”
This means Burry likely opened his new short position after the company’s recent rally on Wall Street, which saw Tesla shares sink in mid-May, only to recover to well over the $400 mark. Currently, shares trade at around $427.
The company saw a big Tuesday as shares climbed considerably, over 10 percent. The size of the Tesla short was not provided, nor did Burry give any information on the position’s structure, the number of shares, dollar value, or whether options were used in the short.
The Tesla and SpaceX merger everyone is talking about is quietly building
Over the years, Burry has been one of the more vocal critics of Tesla, calling its share price “media inflated,” and saying it was “ridiculously overvalued” as recently as December.
The company has largely transitioned away from being known as an automotive company and instead is much more widely regarded as an AI play, mostly due to its Full Self-Driving efforts, Optimus robot development, and data collection related to both.
This has not pulled those skeptics away from being vocal about their distaste for how Tesla is valued, but there’s no denying that the company is a global force in many things, including sustainable energy, automotive, and AI.

SpaceX gets initial stock coverage from Tesla’s biggest bull
Wedbush Securities is initiating stock coverage on SpaceX (NASDAQ: SPCX), marking the first comments on the company since it went public several weeks ago. Wedbush and its analyst handling coverage, Dan Ives, are widely bullish on fellow Musk company Tesla (NASDAQ: TSLA).
Ives wrote his first note initiating coverage of SpaceX shares on Wednesday with a $190 price target and an ‘Outperform’ rating. The firm believes the company is well positioned off of its IPO because of its wide array of projects, including AI compute power and infrastructure, connectivity projects, and launches.
“We view SpaceX as one of the most differentiated assets within the tech market with a strong footprint across its three core markets, with Starlink driving success with connectivity,” Ives wrote, “Starship launches leading to a demand flywheel and increasing deal flow for its Colossus clusters.”

Wedbush leans heavily on Starlink, which they say is the “profitability driver given the strength of its recurring revenue base of ~12 million subscribers as of June 5th.” Ives believes Starlink is still in the “early innings” of penetrating the global telecommunications and broadband market, as it only holds less than a 1 percent share. However, this number is sure to increase over time.
It also highlights the importance of Starship, which it says is an “essential layer” of SpaceX’s overall success. SpaceX developing and displaying the ability to reuse rockets is a major cost and reliability advantage “as it reduces the necessary hardware launch costs while generating a feedback loop for future flights to improve their launch flight rate without accelerating capex spend.”
Finally, SpaceX’s recent AI/Compute projects are also very elementary, Ives writes. It is worth mentioning Wedbush said its $190 price target is derived from a valuation forecast that sees the company yielding roughly $2.48 trillion of implied enterprise value.
There are also some factors that Wedbush did not take into account with its initial coverage. The firm wrote in the note:
“We note that there is optional value coming from Starship’s accelerating scale towards sub-$200/kg unit economics, orbital data centers, and enterprise AI monetization as these factors could drive meaningful upside but these face major hurdles, so we do not take that into account with our valuation.”
SpaceX shares are down just over 2 percent today, trading at around $167 at the time of publication.
