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.

On Friday, Tesla launched the Outlet Adapter that enabled Vehicle-to-Load (V2L) energy transfer, meaning owners could essentially utilize their cars as a power source for things like laptops, electric grills, or string lights.
However, even owners of some of the newest builds of the Model Y are finding out that their cars are not compatible with the new $80 accessory, stirring up a new complaint among members of the community.
Tesla launches V2L Outlet Adapter for Premium Model Y in the U.S.
Upon the release of the Outlet Adapter on Friday, I signed into my Tesla account to order the accessory. However, I was met with the dreaded “This product is not compatible with your 2026 Model Y” message at the bottom of the screen.
Some said their accounts also displayed the same message, but they ordered anyway. However, they might be surprised to find that this is no mistake; some of the newest Model Ys do not have the appropriate Power Conversion System (PCS). Mine, which was ordered on this day last year and delivered on August 31, has the old 48A, single-phase PCS.
Vehicles with the new, two-piece PCS are able to utilize V2L features on their cars:
🚨 Looks like you can hit the Parts Catalog and enter your VIN and check to see if your Model Y will be able to use the adapter for V2L.https://t.co/QA9zRk7n2k
h/t to @SawyerMerritt for finding this out.
I am sad but this isn’t a huge loss. https://t.co/AYpI12QVV9 pic.twitter.com/LRFSrtRywo

Obviously, it’s disappointing. Many owners have taken delivery this year and still can not utilize the Outlet Adapter because their cars feature the old PCS:

It looks like if you have one of these older PCS units, you can upgrade, but the parts alone are $1,750, and that’s before Tesla adds labor for installing. It is honestly more logical to get some kind of portable power supply or power station at that point.
It is great that Tesla has enabled V2L for Model Y vehicles, but it is also unfortunate that vehicles that are less than one year old are not able to take advantage of this awesome new feature.
With that being said, it truly is a first-world problem; can you really complain when Full Self-Driving is available, maintenance is incredibly inexpensive, and the car has been so good through a year of ownership?
Tesla has launched a new Vehicle-to-Load (V2L) Outlet Adapter for Premium Model Y vehicles in the United States, meaning you can now power devices like laptops or light strings with your vehicle’s battery.
It appears the capability will be available for any Model Y Premium trim, including those that were purchased prior to the Adapter being launched. It will also only impact Juniper Model Y vehicles, so the first-gen owners will unfortunately not have access to this capability.
If your Model Y was purchased before Tesla renamed the trim levels to “Premium” and “Standard,” it does not seem to be compatible. My Model Y is technically a Premium build, as it is the Long Range All-Wheel-Drive. However, Tesla says it is not compatible with my vehicle.
🚨 Tesla has launched the Outlet Adapter for Model Y Premium in the U.S., enabling V2L capability for all Premium trims (that’s what it appears to be as it is available for purchase with all Premium trims)
It’s available for $80. 2.4kW max power and rated for 120v, 20A pic.twitter.com/lDxlVIk5s8

For $80, you can now utilize your car as a portable charger for small appliances or devices. This is perfect for things like tailgates, concerts, or camping, as you can now plug in devices that you might use. Those string lights for camping? That laptop for the other games that are on at the tailgate?
They’ll both utilize energy from your Tesla’s battery to be powered. This is the first time Tesla has expanded the capability to vehicles outside of the Model Y Performance and Cybertruck. However, this feature has been highly requested by owners for an extended period of time.
Tesla launched the Outlet Adapter in China last year:
Tesla China rolls out Model Y L V2L adapter, and it’s free for early owners
You will need the Mobile Connector to operate the Outlet Adapter: the Outlet Adapter will plug into the main housing of the Mobile Connector, where the appropriate adapter to charge your vehicle will plug in.
It is rated for 120 volts and 20 amps, and has a max power rating of 2.4kW.
You can buy it here from Tesla for $80.
Tesla is nearing its long-awaited unveiling of the all-electric Tesla Roadster, a new report from The Information claims, as the company has said several times this year that the event would take place “soon.”
Now, it appears there is movement on Tesla’s end regarding when it will happen.
The report says that Tesla will unveil the Roadster as soon as this month with a SpaceX version that will utilize cold-gas thrusters to help the vehicle float for a short period of time. This is something CEO Elon Musk has talked about with the Roadster for years.
🚨 The Information is reporting this morning that Tesla is ready to unveil the “flying” Roadster as soon as this month
It’s almost here, folks. pic.twitter.com/IdL4atsucQ
— TESLARATI (@Teslarati) August 14, 2026
Additionally, due to the delays, Tesla explored “a variety of designs” for the Roadster, potentially planning to abandon the design it showed off for the first time in 2017 and adopting an entirely new aesthetic.
According to The Information, Tesla considered utilizing a repurposed Model S Plaid and even wanted to upgrade the look to something like a Lamborghini Countach.
We’ve heard all of these things before, including teases about the date and how “soon” the Roadster will finally be ready to be shown off to the world (for the second time). Musk said that the event would occur in April, then May, then Chief Designer Franz von Holzhausen continued to say it would be coming “soon.”
We do expect to see the Roadster by the end of the year, and now with this new report swirling, it appears it could be sooner rather than later.
The wait has been incredibly long, but there is likely a good reason for it. Tesla’s desire to make the Roadster the craziest vehicle on the road was non-negotiable, and it likely took a lot of time and resources to develop and perfect into something that was safe and suitable for a vehicle like this.
