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.

SpaceX set to launch astronauts and a classified Falcon Heavy mission on the same day
SpaceX plans three launches Thursday, including Crew-13 astronauts and Falcon Heavy’s first classified NRO mission.
SpaceX is lining up one of the busiest single days in its history, and the company offered a preview on Wednesday morning with a simple post on X: “Sunrise at pad 40.” The video and photos show Falcon 9 standing at Space Launch Complex 40 at Cape Canaveral, roughly a day before it is scheduled to carry four astronauts to the International Space Station.
That launch is only the first of three SpaceX missions planned for Thursday, October 1, across both coasts.

Crew-13 is targeting liftoff at 11:10 a.m. ET, with a backup opportunity Friday at 10:47 a.m. ET. NASA astronaut Jessica Watkins will command the mission, with NASA’s Luke Delaney as pilot and Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov serving as mission specialists. According to NASA, Dragon is set to dock with the forward port of the station’s Harmony module around 8 p.m. ET, less than nine hours after launch. Watkins is the only member of the crew who has flown before, and Kutryk will become the first Canadian to reach orbit through NASA’s Commercial Crew Program.
The Falcon 9 booster is flying for the third time after supporting Crew-12 and a Starlink mission, and it will attempt a landing at Landing Zone 40 beside the pad. That site made its debut in February when the Crew-12 booster touched down there, as Teslarati reported at the time. Crew-13 will relieve the Crew-12 astronauts, who have been aboard the station since the middle of February.
On the West Coast, another Falcon 9 is scheduled to lift off from Vandenberg Space Force Base in a window running from 2:18 to 3:16 p.m. ET, a flight NASASpaceflight lists as a Transporter rideshare mission.
The day is set to close at 11:53 p.m. ET, when Falcon Heavy launches from Launch Complex 39A with NROL-97, the first National Reconnaissance Office payload ever to fly on the rocket. SpaceX rolled the vehicle out to the pad Tuesday night. Its two side boosters, which previously flew GOES-U, ViaSat-3 F3 and NASA’s Roman Space Telescope, will return to Landing Zones 1 and 2, while a new center core will be expended in the Atlantic. The Roman launch took place on August 30, so NROL-97 will come barely a month later as Falcon Heavy’s third flight of 2026 and 14th overall.
NASA taps SpaceX to launch the telescope that could unlock new worlds
If all three Florida boosters land as planned, it would be the first time the Space Coast has seen landings at LZ-40, LZ-1 and LZ-2 on the same day, according to the Orlando Sentinel, which has warned residents in Brevard, Orange and Volusia counties that more than one sonic boom is possible.
The schedule arrives just three days after Starship reached orbit for the first time on Flight 14 from Starbase, Texas, deploying 26 Starlink V3 satellites. If Thursday’s missions stay on time, SpaceX will have flown Starship, Falcon 9 and Falcon Heavy from four different pads in about four days.
Crew-13 is also the start of a longer run for Dragon. NASA recently added Crew-15, Crew-16 and Crew-17 to SpaceX’s contract in a $946 million modification, keeping Dragon as the agency’s only operational ride to the station while Boeing’s Starliner remains grounded.
Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.
The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.
🚨 Tesla designed the integrated thermal systems for Cybercab and Semi at the same time as the vehicles were both in development

— TESLARATI (@Teslarati) September 25, 2026
Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:
“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”
Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”
Priestley also highlighted a practical payoff of the indirect design:
“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”
This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.
The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.
This thermal system is also shared with Cybercab – one thermal system for both our most efficient vehicle & our biggest vehicle
— Tesla Semi (@tesla_semi) September 25, 2026
Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.
Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.
For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.
Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
