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 Semi gets strange-but-understandable comparison from Jay Leno

The Tesla Semi recently received a strange-but-understandable comparison from automotive enthusiast and former long-time late-night television show host Jay Leno.
In a recent interview with MotorTrend, legendary comedian and automotive enthusiast Jay Leno shared his impressions after driving Tesla’s long-range Semi truck, offering one of the most vivid descriptions to date:
“It’s like driving an office building.”
The comparison may seem quirky—office buildings evoke images of immobility rather than motion—but it aptly conveys the experience of commanding a massive 23,000-pound Class 8 electric truck that delivers sports-car acceleration.
Lenotested the production-spec Long Range model, which is rated for up to 500 miles of range. He was visibly impressed by its performance, noting how the enormous vehicle moves with surprising urgency.
“It’s as fast as a Tesla, but it’s like driving an office building,” he remarked. “It’s this huge thing that moves like right now. You go 500 miles. You get 60% charge in 30 minutes. You’re saving on fuel costs. It seems quite good.”

The reaction highlights the cognitive dissonance at the core of the Tesla Semi. Traditional diesel semi-trucks are slow, noisy, and expensive to run. The Semi rewrites the rules with instant torque from its tri-motor electric powertrain, producing up to 800 kW.
Despite its size, the truck feels agile thanks to full electric steering assist, upgraded actuators borrowed from the Cybertruck, and a 48-volt electrical architecture that improves responsiveness and efficiency.
Tesla reports real-world energy consumption below 1.7 kWh per mile for the Long Range version. Megacharger stations can deliver a 60% charge in roughly 30 minutes, making the truck suitable for long-haul operations.
Additional features include an electric Power Take-Off (ePTO) capable of 25 kW for trailer refrigeration or other equipment, and a driver-focused cab with a central seating position for optimal visibility and a quiet, high-tech interior.
Fleet operators stand to benefit significantly from the economics. Diesel trucks often cost nearly one dollar per mile when including fuel, maintenance, and downtime.
Tesla projects the Semi can reduce operating costs to as low as 15 cents per mile through cheaper electricity, regenerative braking that minimizes brake wear, and reduced service requirements. While early deployments, like Pepsi’s, focused on shorter routes, the 500-mile variant targets cross-country applications.
Obstacles remain. A fully loaded tractor-trailer can reach 80,000 pounds, which reduces real-world range compared to the unloaded test conditions. Building out a nationwide Megacharger network will be essential for broader adoption. The Semi also carries a higher upfront price than conventional diesels, though total cost of ownership and available incentives frequently tip the scales in its favor over time.
Tesla Semi hauls fresh Cybercab batch as Robotaxi era takes hold
Leno’s “office building” description resonates because it captures the unexpected thrill of piloting something so large yet so capable. As the trucking industry faces pressure to cut emissions and control rising fuel expenses, the Semi offers a compelling alternative that excels in performance, comfort, and efficiency.
Coming from a man who has driven everything from vintage classics to modern hypercars, Leno’s genuine enthusiasm adds weight to the verdict.
The Tesla Semi is emerging as more than an experimental EV—it represents a practical vision for the future of heavy-duty transport where massive rigs accelerate instantly, and the numbers finally make sense. If fleet results continue to validate the claims, the era of diesel dominance could be drawing to a close.

Tesla expands its mass-market color palette in the U.S.
Delivering a fresh splash of color to its lineup, Tesla is giving U.S. buyers two stunning new blue options that are already turning heads.
Tesla has expanded the color palette it offers on its mass market vehicles in the United States, giving buyers of the Model 3 and Model Y a few additional options than before.
Delivering a fresh splash of color to its lineup, Tesla is giving U.S. buyers two stunning new blue options that are already turning heads. Starting on May 8, the automaker updated its North American configurator to introduce Marine Blue on Model Y Premium trims and Frost Blue exclusively on the Model 3 Performance.

The move replaces the long-running Deep Blue Metallic, a staple for over eight years, and brings previously exclusive shades stateside.
Marine Blue, a deep, rich oceanic hue formerly limited to Europe and Asia-Pacific markets, is now available on Model 3 and Model Y RWD and Long Range AWD Premium variants. Priced at a $1,000 upgrade—standard for Tesla’s premium paints—it delivers a sophisticated, metallic finish that shifts beautifully under light.

Tesla North America highlighted the change directly in an official post, confirming Marine Blue as the new flagship blue for non-Performance models.
Frost Blue, on the other hand, is the real crowd-pleaser for enthusiasts. Previously reserved for the flagship Model S and Model X, this lighter, icy metallic shade is now offered at no extra cost on Model 3 Performance and Model Y Performance trims.

Performance buyers effectively get a premium color included in the base price, a smart perk that Tesla has extended to higher-end variants across the board. Early in-person sightings and configurator renders show Frost Blue’s cool, modern vibe popping against the cars’ sleek lines, especially with black wheels and red brake calipers.
The timing couldn’t be better. With Tesla pushing refreshed Model 3 and Model Y refreshes amid growing competition, these updates add visual excitement without major redesigns.
Deep Blue Metallic orders are being transitioned to the new shades, according to customer reports and Tesla communications. In the U.S., Puerto Rico, and Mexico, the options are live now; Canada sees limited Frost Blue availability on the Model 3 Performance.
Tesla’s color strategy continues to evolve, borrowing from higher-end models to refresh mass-market EVs. Now that we bid farewell to the Model S and Model X, some of their colors might be available on the more widely available Model 3 and Model Y.

Tesla Semi’s official battery capacity leaked by California regulators
A California regulatory filing just confirmed the exact battery size inside each Tesla Semi variant.
A regulatory filing published by the California Air Resources Board in April 2026 has put official numbers on what Tesla Semi owners and fleet buyers have long wanted confirmed: the exact battery capacities of both the Long Range and Standard Range Semi truck variants. CARB is California’s independent air quality regulator, and it certifies zero-emission powertrains before they can be sold or operated in the state. When a manufacturer submits a vehicle for certification, the resulting executive order becomes a public document, making it one of the most reliable sources for confirmed production specs on any EV.
The document lists two certified powertrain configurations. The Long Range Semi carries a usable battery capacity of 822 kWh, while the Standard Range version comes in at 548 kWh. Both use lithium-ion NCMA chemistry and share the same peak and steady-state motor output ratings of 800 kW and 525 kW respectively. Cross-referencing Tesla’s published efficiency figure of approximately 1.7 kWh per mile under full load, the 822 kWh pack supports roughly 480 miles of real-world range, which aligns closely with Tesla’s advertised 500-mile figure for the Long Range trim. The 548 kWh Standard Range pack works out to approximately 320 miles, again consistent with Tesla’s stated 325-mile target.
Here is a direct comparison of the two versions based on the CARB filing and published specs:
| Tesla Semi Spec | Long Range | Standard Range |
| Battery Capacity | 822 kWh | 548 kWh |
| Battery Chemistry | NCMA Li-Ion | NCMA Li-Ion |
| Peak Motor Power | 800 kW | 525 kW |
| Estimated Range | ~500 miles | ~325 miles |
| Efficiency | ~1.7 kWh/mile | ~1.7 kWh/mile |
| Est. Price | ~$290,000 | ~$260,000 |
| GVW Rating | 82,000 lbs | 82,000 lbs |
The timing of this certification is not incidental. On April 29, 2026, Semi Programme Director Dan Priestley confirmed on X that high-volume production is now ramping at Tesla’s dedicated 1.7-million-square-foot facility in Sparks, Nevada. A key advantage of the Nevada location is vertical integration: the 4680 battery cells powering the Semi are manufactured in the same complex, eliminating the supply chain bottleneck that had delayed the program for years.
Tesla’s long-term goal is to reach a production capacity of 50,000 trucks annually at the Nevada factory, which would represent roughly 20 percent of the entire North American Class 8 market. With CARB certification now in hand and the production line running, the regulatory and manufacturing groundwork for that target is in place.
