Tesla Model Y from Giga Texas is just one EPA approval away from first deliveries
Hundreds of Tesla Model Y all-electric crossovers have been spotted in the lots of Gigafactory Texas in the past few weeks, with some being spotted on haulers to be driven to destinations not known. However, haulers will likely be back soon for another logistics mission: to pick up the “Austin-made” Model Ys and take them to customers for delivery.
Tesla will be able to begin delivering units of its Austin-made Model Y all-electric crossover from Gigafactory Texas following the EPA approval of the vehicle, the agency told Teslarati. Currently, the Model Y from Gigafactory Texas is being produced with Tesla’s newest 4680 battery cells and new structural battery pack, has not gained its Certificate of Conformity, a document needed for a vehicle to be introduced into commerce.
Certificates of Conformity are effectively approval by the EPA that a vehicle can enter the stream of commerce. If it is introduced into commerce, the vehicle must have a Certificate of Conformity. The certifications are valid for a single model year, and new model year vehicles make their way to the EPA’s testing facility in Ann Arbor, Michigan every year to confirm they align with the EPA’s emissions standards.
“Prior to offering a vehicle for sale, all carlines in the Light-duty sector must be certified and Fuel Economy test data representing each model type must be submitted to EPA,” the EPA said to Teslarati in a statement. “EPA can confirm that Tesla has received a Certificate of Conformity for the 2022 Model Y Long Range AWD, Model Y Performance AWD (Test Group NTSLV00.0L2Y) and a Certificate for the Model Y RWD (Test Group NTSLV00.0L1Y).” These test groups were certified by the EPA last year, with the 2022 Model Y Long Range AWD and Performance variants gaining their Certificate of Conformity on November 1, 2021. It does not expire until December 31, 2022. The 2022 Model Y RWD, which is the variant that Tesla ultimately did not sell, gained its Certificate of Conformity from the EPA on September 28.

Tesla’s Model Y made in Austin will also be a 2022 Model Y, which would mean it would technically align with the EPA’s Certificates of Conformity, especially as the geographic location of manufacture does not determine whether a vehicle conforms to the EPA’s standards or not. “EPA does not use the build location as a descriptor for a new test group or Certificate of Conformity,” the agency said. Instead, updates in the vehicle’s battery pack can prompt the EPA to consider certifying a vehicle again, even if the changes occur to a car in the same model year. However, the changes made to the vehicle prompted the EPA to certify the Austin-made Model Y separately.
In its 2017 document titled, “EPA Test Procedures for Electric Vehicles and Plug-in Hybrids,” the agency says that Confirmatory Testing for vehicles with the same model year is determined on a case-by-case basis, and the EPA can make a choice to certify a vehicle based on the changes:
“Currently, EPA performs confirmatory testing on all new light-duty electric vehicles and plug-in hybrid vehicles at EPA’s emission testing laboratory in Ann Arbor Michigan. If the manufacturer makes changes to an EV or PHEV that was previously tested at EPA, EPA will decide on a case-by-case basis whether additional EPA confirmatory testing is needed.”
What were the changes Tesla made exactly? The EPA confirmed to us that it could not comment on the status “of preproduction vehicles that are pending new emissions certification until manufacturers introduce them into commerce,” which means the Model Y’s changes are confidential until the car earns its Certificate of Conformity. Tesla did not respond to our inquiries to clarify why the vehicle needed to go through the EPA’s conformity procedure once again. However, Tesla’s most recent Earnings Call provided plenty of color to what the changes that prompted a new certification process likely are, and it has to do with Tesla’s 4680 battery cell.

The Battery Pack likely required the EPA to certify the Model Y once again
During the Q4 2021 Earnings Call, Tesla said that “after final certification of Austin-made Model Y, we plan to start deliveries to customers.” Additionally, during the Earnings Call CEO Elon Musk stated that Tesla was “building the Model Ys with the structural battery pack and the 4680 cells, and we’ll start delivering after final certification of the vehicle, which should be fairly soon.” Read More.
Previous builds of the Model Y, even 2022 model year vehicles, which were built at the Fremont Factory, have not yet used Tesla’s 4680 battery pack or the structural battery pack. Instead, Model Ys built at Fremont in the United States have used the automaker’s previous cell chemistry, the 2170 cell. When the EPA certified Tesla’s 2022 model year vehicles in August 2021, the certifications were for the previous battery pack. Read More.
Tesla Model Y from Giga Texas will equip Structural Battery Pack, 4680 cells
The 4680 batteries differ significantly from the 2170 cell in power, range, and efficiency. Therefore, the Model Y from Texas will have ratings that are substantially different from previous builds from Fremont. The Model Y from Austin needs eMPG ratings for FuelEconomy.gov and Monroney stickers.
Once Tesla is granted a Certificate of Conformity for Model Ys that are set to be produced at Gigafactory Texas, the automaker will be able to deliver the vehicles to customers.
Documents obtained by Teslarati show Tesla’s application to have the Model Y’s AWD and Performance variants certified together, while the RWD build of the car was certified separately. The documents state that each variant of the car conformed with California Air and Resource Board (CARB) standards, as well as Federal Emissions Standards that States which do not align with the CARB standards utilize. Texas withdrew its intentions to adopt CARB standards in 2007, State documents revealed.
States that have adopted CARB standards are New York, Massachusetts, Vermont, Maine, Pennsylvania, Connecticut, Rhode Island, Washington, Oregon, New Jersey, Maryland, Delaware, and most recently, Colorado, which adopted the standards this year.

How long until the Tesla Model Y from Gigafactory Texas is approved by the EPA?
The EPA cannot predict the timing of the certification process, and it varies from vehicle to vehicle. Rough timeframes are available by determining when Tesla submitted an application for a vehicle and when the vehicle gained its Certificate of Conformity.
Tesla’s application for the 2022 Model Y Long Range AWD and Performance variants is dated for October 21, while the Certificate of Conformity is dated November 1. However, this vehicle had a previous model year and utilized the same battery pack. The timeframe may be quicker as the 4680 pack has not been previously tested by the EPA for a passenger vehicle.
When Tesla submitted its application for the 2021 Model Y, it was the first certification process for the vehicle. Tesla submitted the application on December 13, 2019, with the Model Y gaining its Certificate of Conformity about a month later on January 8.
If Tesla submitted its application for the new Model Y on January 26 when it announced it was awaiting certification, deliveries could be approved within the coming days.
4680 Battery Cell
In September 2020, Tesla held “Battery Day” to unveil a new cell and manufacturing design that would increase vehicle safety and structural integrity. Musk unveiled the 4680 cell, a new electric vehicle battery capable of more range, power, and performance while offering a longer life cycle. Tesla has been producing the cell in volume at a facility known as Kato Road near the company’s Fremont factory in Northern California. Until now, no customer has driven a Tesla vehicle equipping the 4680 cell. The Model Y built at the Texas factory will be the first Tesla vehicle to utilize the new 4680 battery pack. Read More.
The vehicle will also utilize Tesla’s structural battery pack, the automaker confirmed. The structural battery pack uses engineering similar to an aircraft wing to use negative mass to increase structural integrity and density. The packs will also use a structural adhesive and flame retardant, attaching cells to the floor and ceiling of the pack, increasing stiffness and preventing major deformation in the event of a crash.

Tesla released Full Self-Driving version 14.3.6 last week, and after what was potentially one of the best FSD releases in v14.3.5, there has been a bit of a regression. While there are some bright spots, the changes made to v14.3.6 seem to have backtracked some behaviors.
Overall, it is hard to really complain about FSD in any sense; it has revolutionized how I travel literally anywhere. According to my self-driving app, the last time I went a day without using it was 59 days ago.
However, I think it’s also important to recognize when things are just plain bad with FSD. There are times it does truly mind-boggling things, and I’ll dive into those here. Additionally, I only had these issues on local roads, not on highways. Highway operation, generally, is always incredible other than the occasional complaint about speed or left lane camping.
With those things being said, my personal experience may not represent others’ experiences. A handful of people have said they have had a similar experience on v14.3.6, while others have said it is more than normal.
Turning Hesitancy, Inaccuracy
I’ve noticed more inaccuracy turning into multi-lane stretches of road than in any version I can remember. I’ve had at least three instances of FSD turning into a stretch of roadway that has two or more lanes, and not selecting a lane confidently as it has in past versions.
I think Tesla FSD v14.3.6 is a regression from previous .3 branches
This version in particular has been incredibly hesitant, jerky, and indecisive at times. There’s actually been two drives that I have decided to not used FSD for the remainder of the trip. These were local trips… pic.twitter.com/YobHDOKRS6

Instead, the car will drive over one of the dashed road lines, and the steering wheel will jerk back and forth before picking the lane. It should be said that it has always picked the correct lane when choosing based on the navigation, but it is still very indecisive. The steering wheel jerking is reminiscent of some of the later versions of v13.
I admit I really hate to see the steering wheel jerking come back. However, I think when Tesla releases v14.3.7, it won’t be present. When there are occurrences of it in FSD versions, it is usually resolved by the following release.
FSD Disregards Manual Turn Signals
This is my biggest bone to pick with FSD other than Navigation issues, but this one seems like it would be such an easy fix.
If Tesla is going to put the word “Supervised” on the end of “Full Self-Driving,” then when I tell the car to do something, it should do it. If I input an increase in speed by pressing the accelerator, the car will immediately respond. It does not disregard my input because it feels it is traveling at the right speed.
FSD should never disobey and turn off turn signals that the driver inputs. Trying to direct the car into the correct lane, I had initiated the left turn signal not once, not twice, but three times, with the car turning it off all three times and continuing in a lane that would end in just one block. The only solution at this point would be to zipper merge.
This goes back to the fact that self-driving’s biggest bottleneck might be rider preference. A zipper merge might have been more than reasonable, might have saved me time that I spent sitting through an additional light cycle, and might be something many drivers would do. I was in no hurry, I traditionally do not try to zipper merge because it feels inconsiderate, and lastly, the car should have just followed my input.
-
This caused me to disengage and drive manually the rest of the way home. Sometimes I just do not need FSD to try to pass every car it can at intersections.
Bird Braking is a Thing of the Past
The big complaint with recent versions of Full Self-Driving has been what we’ve coined as “bird braking,” which is when the car will brake suddenly as a bird flies past.
There have been zero issues with this so far in v14.3.6, which is an excellent improvement.
FSD Might Already Be Taking Note of Driver Preferences
Another thing I have noticed over the past few days is that v14.3.6 seems to already be taking my preferences with navigation into account.
This is something that is supposed to be rolling out with the Summer Update, but I have a hunch it’s already present and might have been included in this v14.3.6 build. On Friday, FSD pulled into an entrance to a local convenience store that it had never attempted to go into before.
Typically, I manually pull into this entrance because it avoids heavy cross traffic at the main entrance. FSD has always chosen that congested main entrance.
I don’t want to get anyone excited but my Tesla running FSD v14.3.6 just:
✅ Pulled into an entrance at my local Sheetz that I routinely pull into manually but FSD never has entered
-✅ Pulled into my assigned parking space at home despite many other spots being vacant https://t.co/ZUShvknTWO pic.twitter.com/83O5a2S0eh
— TESLARATI (@Teslarati) July 24, 2026
Additionally, FSD has pulled into my assigned parking spot at my townhouse community on multiple occasions with this release. This is something that used to happen ocassionally, but not consistently.
It also navigated back to the same convenience store last night, drove through crazy cars scrambling to gas pumps, navigated out of the parking lot correctly, drove me home, and, once again, parked in my assigned spot.
As previously stated, this release just seems to have a few things that need to be brought to Tesla’s attention, and also to make others who use FSD aware of some things that I’ve experienced. I look forward to the next release that will remedy these issues, just as Tesla has always done in the past.

Elon Musk’s massive Terafab project, which will be the first true conglomeration between each of his major entities, is set to get its final location soon, the CEO said on Tesla’s recent earnings call.
“The Terafab, we expect to announce a location soon, and provide more details about our plans in that regard. We’ll leave that to the product, the launch announcement rather than try to squeeze it into an earnings call,” Musk said last Wednesday.
Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
Terafab was announced by Musk back in March and was essentially a massive, vertically integrated semiconductor manufacturing project that would provide all the chips the three companies needed for their AI initiatives without needing third-party companies.
The plant will produce over 1 terawatt of AI compute each year, and will help back up projects like Optimus, Full Self-Driving, and other AI-based projects that Musk’s companies are working on.
In April, less than a month after the project was launched, Intel announced it would join the project, contributing manufacturing expertise and consulting to Terafab as a whole. Intel is one of three chip manufacturers that produce sub-5 nanometer chips at scale. TSMC and Samsung are the other two.
However, there was no true indication of where Terafab would end up, but most believe it will likely be somewhere in Texas. Business Insider has reported that SpaceX plans to build out Terafab in Grimes County, Texas, but this is unconfirmed.

Musk confirmed recently that it would not be on Giga Texas property, as it is simply too large.
The sheer scale of TERAFAB is going to be insane.
Elon said it wouldn’t be suitable for anywhere on Giga Texas property because it’s too big:
“We couldn’t possibly fit the Terafab on the GigaTexas campus. It will be far bigger than everything else combined there.

Terafab holds much of Musk’s grand ambitions for the future within its construct. It holds so much responsibility for the future and the biggest projects that Musk’s companies can imagine.
-
“I think this is a very big announcement and it deserves to have its own day in the spotlight and not be squeezed into an earnings call,” he said. “I do think Terafab is going to be an amazing initiative and a necessary one, and one without which we will be constrained in our ability to scale Optimus production, because we simply won’t have enough AI chips.”
He continued by stating that Terafab is necessary for scaling Optimus, which Musk said could be the biggest product of any kind of all time. “It’s crucial to solve that, and we’ll have to solve memory, logic, and packaging in order to scale Optimus.”
SpaceX performed a secret test on a specific portion of Starship with its recent 13th test flight last week, CEO Elon Musk revealed.
Starship’s 13th test flight took place last Friday, and in many aspects, it was one of the most overwhelmingly successful launches in the project’s history.
All of the mission objectives were met without incident, both the Super Heavy Booster and Ship managed to perform safe splashdowns in the Gulf of America and the Indian Ocean, respectively, and the deployment of Starlink satellites came and went without any complications.
— Elon Musk (@elonmusk) July 25, 2026
However, there was more on the agenda for SpaceX with Flight 13. Musk revealed an internal test of the ship’s heat shield tiles, as the space exploration company wanted to push them to the limits after previous issues.
Many noticed that Starship’s initial launch seemed to be more accelerated than normal, and that was not a mistake. Musk revealed that SpaceX decided to give Flight 13 an intentionally aggressive acceleration rate in an effort to test how well the tiles would remain attached to the ship:
-
This flight intentionally had much higher acceleration to test how well the heat shield tiles would remain attached at high dynamic pressure.
Test was successful.
— Elon Musk (@elonmusk) July 25, 2026
SpaceX had issues with some of the heat shield tiles remaining attached early on in the Starship program. The first six test flights presented some kind of anomaly with them, so the company’s big focus with them was to figure out a way to keep them intact through the duration of the flight.
Things truly improved as Flight 10 showed that ceramic tiles generally stayed attached to the ship far better due to refined attachment, as SpaceX utilized pins instead of adhesives. Flights 10 through 13 truly showed some clear progress with the heat shield tiles, and this latest test seems to be where some real progress was noticed, especially by Musk.
The 13th Starship launch last Friday was the second with Starship V3, SpaceX’s latest and greatest iteration of the spacecraft. Goals and ambitions are getting even grander as the project continues to progress. Musk has already hinted that SpaceX will likely try to catch Starship with Flight 14.
