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 has taken home the “Overall Loyalty to Make” award from S&P Global Mobility for the fourth consecutive year, reinforcing Tesla owners’ willingness to come back. The 2025 awards are based on S&P Global Mobility’s analysis of 13.6 million new retail vehicle registrations in the U.S. from October 2024 through September 2025. The complete list of 2025 winners includes General Motors for Overall Loyalty to Manufacturer, Tesla for Overall Loyalty to Make, Chevrolet Equinox for Overall Loyalty to Model, Mini for Most Improved Make Loyalty, Subaru for Overall Loyalty to Dealer, and Tesla again for both Ethnic Market Loyalty to Make and Highest Conquest Percentage.
Tesla’s streak in this category started in 2022, and the brand has now won the Highest Conquest Percentage award for six straight years, meaning it keeps pulling buyers away from other brands at a rate no competitor has matched. Tesla’s retention among Asian households reached 63.6% and among Hispanic households 61.9%, rates that significantly outpace national averages for those groups. That breadth of appeal across demographics adds a layer of significance to a win that some might dismiss as routine.
The timing matters too. After several consecutive quarters of decline, Tesla’s share of U.S. EV sales jumped to 59% in Q4 2025. That rebound, arriving just as competitors were flooding the market with new models and incentives, suggests Tesla’s loyalty numbers are not simply the result of limited alternatives. Buyers are still choosing it when they have plenty of other options.
What keeps Tesla owners coming back has a lot to do with the and convenience of charging. The Supercharger network is the most straightforward example. With over 65,000 Superchargers globally, it remains the largest and most reliable fast-charging network in the world, and owners who have built their routines around it face a real practical cost when considering a switch. Competitors have made progress, but the consistency, speed, and availability of Tesla’s network is still the benchmark the rest of the industry is chasing. Then there is the software side. Tesla has built a model where the car you own today is functionally different from the car you bought two years ago, through over-the-air updates that add continuous game-changing improvements such as Full Self-Driving that has moved from a driver-assist feature to an increasingly capable autonomous system. For many Tesla owners, leaving the brand means starting over with a car that will not get meaningfully better over time, and that is a trade-off fewer and fewer are willing to make.
Tesla Robotaxi services in Austin have been operating since last Summer, but Tesla has admittedly been delayed in its expansion of the geofence, fleet size, and other details in a bid to prioritize safety as new technology rolls out.
But those barriers are being broken with new guardrails being removed from the program.
Tesla has achieved a significant advancement in its autonomous ride-hailing program. As of May 4, the Robotaxi fleet in Austin, Texas, has begun operating unsupervised during evening hours for the first time. This expansion moves beyond previous limitations that restricted unsupervised service to daylight hours, typically ending in mid-afternoon.

The change brings Austin in line with operations in Dallas and Houston. Those cities have supported evening unsupervised runs since their initial launches in April, and both recently received additions of new unsupervised vehicles to their fleets. This coordinated progress across Texas strengthens Tesla’s regional presence and provides a broader testing ground for the technology.
This milestone carries substantial weight in the development of autonomous vehicles. Extending operations into low-light conditions meaningfully expands the Robotaxi’s operational design domain (ODD)—the specific environments and scenarios in which the system is approved to operate safely without human intervention.
Nighttime driving presents unique technical demands: diminished visibility, headlight glare from oncoming traffic, reduced contrast for identifying pedestrians and lane markings, and greater variability in camera sensor exposure.
Tesla’s pure vision approach, powered by neural networks trained on vast real-world datasets rather than lidar or pre-mapped routes, must handle these variables reliably. Demonstrating consistent unsupervised performance after sunset validates the robustness of the end-to-end AI stack and its ability to generalize across diverse lighting conditions.
Beyond technical validation, the expansion holds important operational and economic implications. Evening hours often coincide with peak urban demand for rides, including commutes, dining, and entertainment outings.
Enabling service during these periods increases daily vehicle utilization, allowing each Robotaxi to generate more revenue while gathering additional high-value training data. Higher utilization accelerates the virtuous cycle of data collection, model improvement, and further ODD growth.
Looking ahead, this step paves the way for more ambitious rollouts. Success in low-light environments positions Tesla to pursue near-24-hour operations, potentially integrating highways and expanding into varied weather patterns. Regulators worldwide frequently demand evidence of safe performance across day-night cycles before granting wider approvals.
Proven capability in Texas could expedite deployments in planned cities such as Phoenix, Miami, Orlando, Tampa, and Las Vegas during the first half of 2026.

Moreover, scaling evening service supports Tesla’s long-term vision of a high-efficiency robotaxi network. Greater fleet productivity lowers the cost per mile, making autonomous mobility more accessible and competitive against traditional ride-hailing.
As the company iterates on software updates informed by nighttime data, reliability is expected to compound rapidly, unlocking denser urban coverage and longer-distance trips.
In summary, the introduction of an unsupervised evening Robotaxi service in Austin represents more than an incremental schedule adjustment. It signals a critical maturation of the underlying technology and sets the foundation for broader geographic and temporal expansion.
With Texas operations gaining momentum, Tesla is steadily advancing toward transforming urban transportation at scale.

Tesla Cybercab just rolled through Miami inside a glass box
Tesla paraded a Cybercab in a glass display at Miami’s F1 Grand Prix event this week.
Tesla set up an “Autonomy Pop-Up” at Lummus Park in Miami Beach from April 29 through May 3, 2026, embedded within the official F1 Miami Grand Prix Fan Fest. The centerpiece was a Cybertruck towing the Cybercab inside a glass display case marked “Future is Autonomous,” rolling through the beachfront crowd.
Miami is on Tesla’s confirmed list of cities for robotaxi expansion in the first half of 2026, making the promotion a strategic promotion that lays groundwork in a target market.
This was not Tesla’s first time using Miami as a showcase city. In December 2025, Tesla hosted “The Future of Autonomy Visualized” at its Miami Design District showroom, coinciding with Art Basel Miami Beach. That event featured the Cybercab prototype and Optimus robots interacting with attendees. The F1 pop-up this week marks Tesla’s return to Miami and follows a pattern Tesla has been running since early 2026. Just two weeks before Miami, Tesla stationed Optimus at the Tesla Boston Boylston Street showroom on April 19 and 20, directly on the final stretch of the Boston Marathon, letting tens of thousands of runners and spectators meet the robot for free, generating massive earned media at zero advertising cost.

Tesla has confirmed plans to expand its robotaxi service to seven cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas, building on the unsupervised service already running in Austin. Musk has said he expects robotaxis to cover between a quarter and half of the United States by end of year. On the production side, Musk told shareholders that the Cybercab manufacturing process could eventually produce up to 5 million vehicles per year, targeting a cycle time of one unit every ten seconds. Scaling robotaxis to 10 million operational units over the next ten years is a key condition of his compensation package, alongside selling 20 million passenger vehicles.
As for the Cybercab’s price, Musk has said buyers will be able to purchase one for under $30,000, with an average operating cost around $0.20 per mile. Whether those numbers hold through full production remains to be seen.
