The Tesla Semi has been proving itself in real-world situations, with the company’s fleet of all-electric Class 8 trucks transporting over 20,000 battery packs from Gigafactory Nevada to the Fremont Factory. The update was shared by Tesla Senior Manager for Semi Truck Engineering Dan Priestley, who recently provided some insights on the US Environmental Protection Agency’s (EPA) Phase 3 rules.
The EPA recently announced a final rule, “Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles – Phase 3.” As stated by the agency on its official website, the rule sets stronger standards to reduce greenhouse gas emissions from heavy-duty vehicles beginning in model year 2027. Vehicles covered by the new standards include large trucks like day cabs and sleeper units.
The EPA’s Phase 3 rules were praised by Priestley, who noted that the Tesla Semi has been proving that all-electric trucks can run the same route and carry the same load as diesel trucks at a significantly lower operating cost. Priestley added that Tesla’s fleet of Semi units have transported over 20,000 battery packs from Giga Nevada to the Fremont Factory. The executive also noted that he believes full market adoption of all-electric trucks like the Tesla Semi might happen faster than expected.

“Every day, the Tesla Semi demonstrates that battery electric trucks can directly replace diesel trucks. With our own fleet of Semis, Tesla has shipped >20,000 battery packs out of Gigafactory Nevada to support Fremont vehicle builds. These trucks run the same route, carrying the same load (no load reduction for weight) as the diesel trucks running this route but at substantially lower operating cost. Now, it’s about scale.
“The EPA Phase 3 rules will help hasten the overall fleet transition to zero emissions and address the harmful particulate emissions and other pollutants from diesel trucks. In combination with the superior economics and experience that battery electric trucks provide, I expect full market adoption will occur faster than many think,” Priestley wrote in a post on X.

Tesla Vice President of Public Policy and Business Development Rohan Patel also praised the EPA’s proposal. In a post on X, Patel noted that the pollution standards would help accelerate the electrification of the trucking industry. He also shared the same sentiments as Priestley by stating that the Tesla Semi is already proving on a daily basis that zero emissions trucks will dominate the market in the future.
“Michael Regan is back at it again with a solid EPA proposal to address the significant public health impacts of air pollution from the heavy-duty trucking vehicle fleet. These pollution standards will help jumpstart electrification of the trucking industry. The Tesla Semi is proving on a daily basis that zero emission trucking will dominate in the near future. We are in the process of building a manufacturing facility at Giga Nevada to significantly increase production,” Patel noted.

SpaceX Starship just nailed something it’s never done before
SpaceX’s Starship flew successfully Friday, landing both stages and deploying its first Starlink V3 satellites.
Starship’s thirteenth test flight delivered exactly what SpaceX needed with a clean liftoff, two successful stage recoveries, and the first real payload the vehicle has ever carried to space. Booster 20 and Ship 40 lifted off at 5:51 p.m. CT from Starbase, and by the time the mission wrapped roughly an hour later, both halves of the rocket had done exactly what they were supposed to do.
Booster 20 separated from Ship 40 a few minutes into the flight and stuck a controlled splashdown in the Gulf of Mexico about six minutes after liftoff. That is a meaningful turnaround from Flight 12 in May, when the booster lost several engines during its boostback burn before a hard water landing attempt.

Starship 40’s performance was arguably the bigger win. The vehicle deployed the first 20 operational Starlink V3 satellites Starship has ever carried, then flew a suborbital arc to a landing in the Indian Ocean that SpaceX commentator Dan Huot called the company’s softest splashdown yet. “This is a dream scenario for this team that’s trying to get this heat shield data,” Huot said on the live broadcast, according to Space.com’s live coverage. “I’m a little over the moon right now. Wow. Lucky number 13.”
Unlike the mass simulators SpaceX flew on Flight 12, these were production Starlink V3 satellites, meant to extend solar arrays and antennas and attempt to link with the broader constellation before reentering minutes later. Getting real hardware through a full deploy sequence on only the second flight of the V3 generation keeps Starship on schedule for the payload work NASA is counting on for future Artemis lunar landings.
What an awesome launch, really seems like everything went super well and it was all incredibly smooth.

The flight also arrives at a moment when SpaceX needed a win. SPCX has traded below its $135 IPO price since mid-July, as Teslarati reported when the mission slipped to Friday, and short interest has climbed to roughly a third of the tradable float. A clean flight will not fix a balance sheet, but it does answer the one question SpaceX absolutely needed answered this week: whether the fixes made after the July 16 abort would hold up under real flight conditions. They did, on both stages, on the first try after the redesign.
SpaceX has not set a target date for Flight 14, though the company has said it wants to push toward an orbital attempt on the next mission. After Friday, that goal looks a lot more within reach.

Tesla’s Supercharger Diner probably just secured more locations
Tesla’s Supercharger Diner in Los Angeles dominated the company’s global usage rankings after just one year, proving the concept is more than just a one-off novelty location that will fade away.
The performance could incite the company to build more locations, something that CEO Elon Musk has hinted at for some time.
Tesla’s Supercharger Diner delivered 21.2 GWh of energy in its first year of operation, the company’s head of Charging, Max de Zegher, revealed on X. Of the top 10 most utilized Supercharger locations in Tesla’s global infrastructure, the Diner in Los Angeles was the most used by drivers, and it wasn’t particularly close:
Tesla Diner opened exactly 1 year ago. Inspiring that futuristic places like this exist.
It’s our highest usage Supercharger in the world: 21.2 GWh delivered in a year, 1.6k sessions/day.

On its launch day one year ago, nobody was too sure what the Tesla Diner would be about. It seemed like an interesting concept, and considering it had been in the works for years, it was a highly anticipated launch that many were looking forward to.
Based on its success, we could see additional Diners with Superchargers built throughout the United States, and potentially beyond. Musk has said on several occasions that the company would be willing to bring the Diner idea to more markets.
Tesla makes major change at Supercharger Diner amid epic demand
Of the markets that Musk has mentioned, both Palo Alto and Austin have come to be perceived as ideal selections. However, there are no concrete plans as of now to build new Supercharger Diners anywhere; the location on Santa Monica Boulevard will remain the exclusive spot to pick up Tesla-inspired eats, at least for the time being.

Tesla short sellers win big after shares fall after earnings
Tesla short sellers won big following the company’s massive fall on Wall Street after it reported subpar Earnings on Wednesday.
Tesla short sellers collected about $4.12 billion in single-day profits on Thursday, according to Bloomberg. Shares fell as much as 15 percent during Thursday’s session. It closed as one of the worst days for Tesla on Wall Street in the past three years.
Investors sold off the stock after Tesla said it would aggressively direct its spending toward AI and its Optimus robot project. The company had record revenues, which were driven by one of the strongest quarters in terms of vehicle deliveries in company history.
However, it missed EPS estimates by reporting just $0.33, a far cry from the $0.53 analysts expected.
S3 Partners reported that about 3 percent of Tesla’s outstanding stock is sold short. Managing Director at S3, Ihor Dusaniwsky, provided the short seller’s potential profit, as well as another figure: shorts have likely had paper gains of $8.92 billion this year, as Tesla shares are down 30 percent in 2026.
Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue
Tesla has burned short sellers many times in the past, but the company’s latest Earnings Call was a chance for those skeptics to taste some payback. Although the company gave some very transparent information regarding future projects, the rollout of Robotaxi, Optimus, and Semi, many investors took their profits on Thursday.
Notable short sellers like Michael Burry have been transparent about their skepticism around Tesla shares. Burry just revealed three weeks ago that he had opened up a new short on the stock, stating he shorted Tesla shares at $416.22. “Happy it jumped back to this level,” he said in a blog post.
At the time of publication, Tesla shares were down about 3 percent and the stock was trading at $309.92.
