Tesla files to expand Fremont factory, make Model Y ‘tent’ permanent
Tesla has filed an application with the City of Fremont to expand its vehicle production facility by 64,000 square feet. The application describes plans to implement foundations and install below-ground utilities under General Assembly 4.5 (GA 4.5), where the Model Y production lines are located at the Fremont factory.
GA 4.5 is currently a tent, or spring structure, that sits outside of Tesla’s Fremont factory. It has been home to the Model Y production and possibly the Model 3 as well since February 2020. According to past permit filings with the City of Fremont’s local government, Tesla initially opened the tent outside during this time and has added to the tent on several occasions.

Tesla is now looking to make GA 4.5 permanent by adding a 64,000 square foot structure onto the Fremont factory. The spring structure that was used before was erected in a pinch as Tesla was planning to begin the production of the Model Y but didn’t have the space for it with Model S, Model X, and Model 3 production all going on under the same roof.
The filing, known as BLD2021-05126, also called Foundations for GA 4.5 South Expansion, states:
“Foundations and underground utilities for proposed 64,000 sf south expansion.”

Tesla will add GA 4.5 to the Southern portion of the Fremont factory, expanding the factory itself, and at the same time, making the 4.5 assembly lines permanent with foundational structures and underground plumbing and electrical work.
It seems that it was only a matter of time before Tesla expanded the Fremont factory to make way for more projects. While demand continues to expand globally, Tesla is still funneling many of its vehicles from the Fremont factory in Northern California. The plant handles global Model S and Model X demand, while Model 3 demand is split with Giga Shanghai. Some Model 3s from Fremont have made their way to other countries that aren’t in North America, but it seems that Giga Shanghai is taking some of the load, especially in the European market.

Here is my understanding of the general assembly lines at Fremont:
• GA1/2 Model S/X (GA1&2 merged into a single line)
• GA3 Model 3
• GA4 Model 3 or Y (tent)
• GA4.5 Model 3 or Y (tent, under construction)
• GA5 Model 3 or Y (indoors next to GA1&2, under construction)— Troy Teslike (@TroyTeslike) July 5, 2020
Last year, Tesla expanded the Model Y production lines to make way for the IDRA Giga Press. This was filed in July 2020, and the Giga Press is now operational at the facility and is cranking out single-piece rear castings for the Model Y crossover. Tesla attempted to expand GA 4.5 in April but had to solve issues with stormwater drainage before the project was ultimately approved.
The Fremont factory has been in Tesla’s possession since 2010 after the company purchased it from Toyota’s New United Motor Manufacturing, Inc. The first Model S rolled off the lines at Fremont in 2012, and the company has made numerous improvements to the facility since being in its possession. The expansion of the facility to make GA 4.5 permanent will alleviate space constraints, allowing Tesla to build more of its all-electric vehicles for a constantly growing and expanding consumer base.
Tesla didn’t immediately respond to Teslarati’s inquiry about the expansion.
Here’s a recent flyover of the Fremont Factory by Gabeincal.
The Tesla Model X has always been one of the company’s most loved vehicles, despite its low sales figures, which can be attributed to its high price tag.
However, the Model X has been a signature item on Tesla’s menu of cars, most notably recognized by its Falcon Wing Doors, which are aware of its surroundings and open according to what’s around it.
But recent improvements to the Model X were looking slim to none, but it appears most of the fixes actually happened under the body, at least according to Tesla’s Vice President of Powertrain, Lars Moravy.
In a recent interview with Car and Driver, Moravy detailed all of the changes to the 2026 iteration of the vehicle, which was about 400 pounds lighter than it was originally. The biggest change is a modification with the rear motor, switching from an induction-type motor to a permanent-magnet design and optimizing the half-shafts, which shed about 100 pounds.
Tesla also got “almost 80 pounds out of the interior bits and pieces,” which “included making parts thinner, different manufacturing process choices, and incorporating airbag-deployment requirements into the headliner fabric,” the report said.
Additionally, the standard five-passenger, bench seat configuration saved 50 pounds by ditching pedestal mounting. This also helped with practicality, as it helped the seat fold flat. Engineers at Tesla also saved 44 pounds from the high-voltage wiring through optimizing the wiring from the charge-port DC/DC converter and switching from copper to aluminum wiring.

Tesla also simplified the cooling system by reducing the number of radiators. It also incorporated Nürburgring cooling requirements for the Plaid variant, which saved nearly 30 pounds.
Many Tesla fans will be familiar with the megacastings, manufactured in-house by presses from IDRA, which also saves more than 20 pounds and boosts torsional stiffness by around 10 percent. Tweaks to the suspension also saved 10 pounds.
People were truly disappointed with what Tesla did with the Model S and Model X, arguing that the cars needed a more severe exterior overhaul, which might be true. However, Tesla really did a lot to reduce the weight of the vehicle, which helps increase range and efficiency. According to Grok, every 200 pounds removed adds between 7 and 15 percent to range estimations.
This makes sense considering the range estimations both increased by 7 percent from the Model X’s 2025 configuration to the 2026 builds. Range increased on the All-Wheel-Drive trim from 329 miles to 352 miles, while the Plaid went from 314 miles to 335 miles.
Tesla has officially launched its first branded Supercharger just months after initiating a new program that allows third-party companies to brand their own charging piles.
The site opened in Land O’ Lakes, Florida, and features eight V4 Supercharging stalls offering up to 325 kW of charging speed. It appears it was purchased by a company called Suncoast Credit Union. This particular branch is located Northeast of Tampa, which is on the Gulf of Mexico.
It features graphics of Florida animals, like alligators:

Tesla launched this program back in September, and it basically was a way to expand its Supercharger presence and also allow companies to pay for the infrastructure. Tesla maintains it. When it announced the “Supercharger for Business,” it said:
“Purchase and install Superchargers at your business. Superchargers are compatible with all electric vehicles, bringing EV drivers to your business by offering convenient, reliable charging.”
The program does a few things. Initially, it expands EV charging infrastructure and makes charging solutions more readily available for drivers. It can also attract people to those businesses specifically.

The chargers can also be branded with any logo that the business chooses, which makes them more personalized and also acts as an advertisement.
The best part is that the customers do not have to maintain anything about the Supercharger. Tesla still takes care of it and resolves any issues:
“We treat your site like we treat our sites. By providing you with a full-service package that includes network operations, preventative maintenance, and driver support, we’re able to guarantee 97% uptime–the highest in the industry.”
It appears the Superchargers will also appear within the in-car nav during routing, so they’ll be publicly available to anyone who needs to use them. They are still available to all EVs that have worked with Tesla to utilize its infrastructure, and they are not restricted to people who are only visiting the business.
Tesla has revealed its Cybertruck light bar installation fix after a recall exposed a serious issue with the accessory.
Tesla and the National Highway Traffic Safety Administration (NHTSA) initiated a recall of 6,197 Cybertrucks back in October to resolve an issue with the Cybertruck light bar accessory. It was an issue with the adhesive that was provided by a Romanian company called Hella Romania S.R.L.
Tesla recalls 6,197 Cybertrucks for light bar adhesive issue
The issue was with the primer quality, as the recall report from the NHTSA had stated the light bar had “inadvertently attached to the windshield using the incorrect surface primer.”
Instead of trying to adhere the light bar to the Cybertruck with an adhesive, Tesla is now going to attach it with a bracketing system, which will physically mount it to the vehicle instead of relying on adhesive strips or glue.
Tesla outlines this in its new Service Bulletin, labeled SB-25-90-001, (spotted by Not a Tesla App) where it shows the light bar will be remounted more securely:
The entire process will take a few hours, but it can be completed by the Mobile Service techs, so if you have a Cybertruck that needs a light bar adjustment, it can be done without taking the vehicle to the Service Center for repair.
However, the repair will only happen if there is no delamination or damage present; then Tesla could “retrofit the service-installed optional off-road light bar accessory with a positive mechanical attachment.”
The company said it would repair the light bar at no charge to customers. The light bar issue was one that did not result in any accidents or injuries, according to the NHTSA’s report.
This was the third recall on Cybertruck this year, as one was highlighted in March for exterior trim panels detaching during operation. Another had to do with front parking lights being too bright, which was fixed with an Over-the-Air update last month.
