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.
Elon Musk told The Economist that artificial intelligence will likely surpass the combined intelligence of every human on Earth within about five years, and that humans may not remain in charge once that happens. In a wide-ranging interview with editor-in-chief Zanny Minton Beddoes, recorded at Giga Texas for the outlet’s Insider series, Musk compared the widening gap between AI and human intelligence to the gap between humans and chimpanzees.
“It’s hard to imagine that the chimpanzee would be in charge,” he said, addressing what happens to human authority once AI moves far beyond us.
Elon Musk reiterates his most optimistic prediction yet with “UHI” forecast
Musk’s timeline stretches out from there. Five years for AI to out-think humanity combined, ten years before humans lose meaningful control, and by 2036, he says, money itself may stop mattering.
Musk notes that if robots and AI produce more goods and services than people could ever consume, currency loses its purpose. He told Beddoes that governments could respond with direct payments, what he called “universal high income,” a term he first used in an X post last August describing a future where “everyone will have the best medical care, food, home, transport and everything else.”
There will be universal high income (not merely basic income).

Sustainable abundance.

He also floated a more surprising prediction that deflation, and not inflation, would become the bigger economic problem, since expanding the supply of goods and services faster than the money supply grows would push prices down rather than up.
None of this is new territory for Musk, who has spent years describing an “age of abundance” built on Optimus and autonomous vehicles. What’s notable is the timing. The interview landed the same week Tesla shares dropped roughly 19 percent following a second quarter earnings report that beat on revenue but missed badly on profit, and as SpaceX stock continues to slide from its post-IPO peak.
Musk’s own net worth has fallen close to $700 billion since mid-June, according to the Bloomberg Billionaires Index, even as he describes a future where personal wealth stops being the point.
Musk did not dodge the risk side of the equation either. He put the odds of AI contributing to human extinction somewhere in the 10 to 20 percent range, then arrived at what he called his “philosophical conclusion” since the technology cannot realistically be stopped and the arguably better response is to keep building it and hope the outcome leans toward abundance rather than catastrophe. “I’ve gone from exhilaration to terror regarding AI,” he told Beddoes, “even intraday.”
Tesla is adding a new “Traction Control Modes” feature to its cars for better handling in any conditions. These features will roll out to the Model 3 and Model Y, the two vehicles in Tesla’s lineup that typically do not have drive modes for various conditions.
Tesla did include this in the Model S and Model X, as well as the Cybertruck.
The new feature will roll out with the 2026 Summer Update, which Tesla announced last week and subsequently started rolling out to some owners today. The Summer Update is the latest iteration of the usual four seasonal releases the company rolls out throughout the year. These releases typically feature some owner-requested features, as well as improvements to things like the Full Self-Driving suite.
Tesla reveals 2026 Summer Update with crazy fixes to Nav and more
This release is no different. Among the changes are improvements to Navigation, new customization options with wraps and how they can be shared and stored, more functionality with the Tesla smartphone app, and new gamification with self-driving.
However, Tesla announced today that it was adding another feature to the Summer Update. Traction Control Modes will now be available with the release
Tesla describes them:
-
“Choose from three updated Traction Control Modes: Auto for normal driving conditions, Slippery Surface for icy or wet roads, Stuck Assist when stuck in snow, mud, or sand. The mode resets to Auto at the start of each drive. To select, go to Controls > Dynamics > Traction Control Mode.”
Tesla’s 2026 Summer Update also includes new Traction Control Modes

The use of these modes will help improve a Tesla’s overall performance in less-than-ideal conditions. Typically, these traction control modes monitor wheel speed through sensors and track engine power to adjust responsiveness in various conditions.
These drive modes are not an ultimate solution to all driving conditions; just because there is a “Stuck Assist,” doesn’t mean your Tesla will dig itself out of a foot-and-a-half trench during a blizzard. It is important to remember that some of these scenarios also require some assistance from the driver. For example, driving in sand requires tires to be aired down significantly to increase traction and control.
However, this will be a welcome addition for those who use the Full Self-Driving suite and might not be convinced of its performance in adverse conditions. Some of us prefer to be in control in rain, snow, or ice, which is totally understandable. However, adjusting the Traction Control Mode while utilizing FSD in snow, rain, or ice could increase confidence and overall experience.

Tesla’s Summer Update is already rolling out to some owners, so it should be making its way to most of the fleet over the next several weeks. The Spring Update rolled out at a very conservative pace, so if you don’t have it by the end of August, don’t be too upset. It might just be Tesla’s method.
Just hours after Starship Flight 13 achieved a successful soft splashdown of its upper stage in the Indian Ocean on July 24, Elon Musk announced an ambitious next step for the company’s next launch of the rocket.
“Unless we discover problems after mission data review, SpaceX will attempt to catch the ship with the tower on [the] next flight,” the SpaceX CEO posted on X on Friday.
That “next flight” is expected to be Flight 14. The plan involves returning the Starship upper stage, commonly called the “ship,” to the Starbase launch tower in Texas and catching it mid-air using the same mechanical “chopsticks” arms that have already proven themselves with the Super Heavy booster.

A successful catch would mark the first time an orbital-class upper stage has been recovered this way, advancing SpaceX’s goal of full and rapid reusability for the entire vehicle.
SpaceX has already demonstrated the tower-catch technique multiple times with Super Heavy. The first successful catch came on Flight 5 in October 2024, when Booster 12 was plucked from the sky by the Mechazilla arms. Subsequent flights, including those involving Boosters 14 and 15, repeated the feat. Several of those recovered boosters were later inspected, refurbished, and flown again, proving the system’s viability for quick turnaround.

Traditional reusable rockets, such as SpaceX’s own Falcon 9 or Blue Origin’s New Shepard, land on legs either on land or droneships. Rocket Lab has recovered its small Electron first stages by helicopter, but those are far lighter vehicles.
SpaceX Starship just nailed something it’s never done before
The China Academy of Launch Vehicle Technology (CALT), a subsidiary of the China Aerospace Science and Technology Corp. (CASC), completed a catch of its booster on July 10. They are the only entity besides SpaceX to attempt and complete the feat.
Flight 13 provided encouraging data. The ship executed a controlled reentry, flipped, and soft-landed intact in the ocean after deploying Starlink satellites, offering the first clear post-splashdown views of an undamaged heat shield. The Super Heavy booster, meanwhile, experienced a harder splashdown in the Gulf of Mexico.
Musk has previously stressed that ship catches would only follow multiple successful soft ocean landings to minimize risk of debris over land.
If Flight 14 succeeds, SpaceX would take a major stride toward routine, rapid reuse of both stages—critical for lowering launch costs and supporting ambitious plans for lunar and Mars missions. For now, teams are reviewing the Flight 13 data. Should everything check out, the next Starship flight could deliver one of the most spectacular recoveries in aerospace history.
