Tesla’s Gigafactory formula rose from a humble “tent” at the Fremont Factory
Back in 2018, Tesla was in a very different place. The company was struggling to release the Model 3, and it was behind on Elon Musk’s aggressive self-imposed vehicle production targets. The Fremont Factory’s assembly lines were not producing enough Model 3s, and it seemed like the company was poised to fail. Critics and shorts circled Tesla like sharks smelling blood in the water. But something unexpected happened, and things were never the same after.
Throwing convention out the window, Tesla built another Model 3 line inside a massive sprung structure at the Fremont Factory grounds, which CEO Elon Musk fondly called a “tent” online. The structure, dubbed as GA4, was mocked to the highest degree, used as a joke by critics, and dismissed outright by skeptics. However, what was almost unknown at the time was that Tesla might have actually stumbled into something special with its sprung structure-based line. By building a simple, straight, Model 3 line inside a “tent,” Tesla seems to have effectively created a solid Gigafactory formula.
No standard automotive solution could be built in time, so we created a new solution. It is working & has slightly higher quality than the more traditional general assembly line. Perhaps most surprising is that the total cost of production in the Sprung tent is lower.

A Practical Concept
The sprung structure-based Model 3 line was the brainchild of Automotive President Jerome Guillen, widely known as Elon Musk’s “problem solver” back in the Model S’ early days. The “tent”-based line followed a relatively simple system, with vehicles being assembled progressively the further they moved into the tent. Even GA4’s loading bays were placed on the sides of the structure, allowing Tesla to take deliveries into the line efficiently. Musk was enthusiastic about the sprung structure on Twitter, noting not long after the “tent” was built that the vehicles produced in the site had “slightly higher quality” than cars made elsewhere.
These humble but creative beginnings appear to have become the heart of Tesla’s Gigafactory formula, one used in Giga Shanghai and Giga Berlin, and seemingly improved further with Gigafactory Texas. This could be seen in the design and processes that Tesla has adopted so far in its Shanghai and Berlin plants, both of which invoke the image of a scaled-up, refined, and optimized version of Fremont’s “tent.”
A Gigafactory Formula
Tesla critics typically overlook the fact that the Fremont Factory is a legacy car plant at its core. It’s an expansive facility, and it is impressive in its own right, but it’s not a site developed specifically to produce all-electric cars. Thus, for the Model S, Model X, and the Model 3’s early days, Tesla was essentially developing a system that makes EVs at scale using a facility designed initially to manufacture cars equipped with the internal combustion engine.
Of course, Tesla has made numerous adjustments to make the Fremont Factory into one of the most advanced electric vehicle plants in the market. However, it is difficult not to be impressed with Tesla’s quick production ramp and flexibility in Gigafactory Shanghai, arguably the first EV factory that the company built using its GA4 formula, with its simple production lines to its numerous loading bays at its side. This concept seems to have been carried over to Gigafactory Berlin, which is expected to ramp its operations at a rate that rivals even that of Giga Shanghai.
A Matter of Scale
Ultimately, it appears that GA4 was Tesla’s “eureka” moment of sorts, at least for its electric vehicle factories. By scaling up and refining the sprung structure-based concept, Tesla was able to create monster factories like Giga Shanghai, and later this year, Gigafactory Berlin as well. However, this is not all as Tesla seems to be adopting an updated design for Gigafactory Texas, with its three main buildings built parallel with each other. Little is known about the reasons behind Giga Texas’ design, but there’s little doubt that the expansive facility will be very impressive when completed nonetheless.
Prior to the Model 3’s “production hell,” Elon Musk spoke about Tesla’s “Alien Dreadnought” factories, which are supposed to be so automated and advanced that they would resemble alien facilities featured in sci-fi fiction. Tesla seems to have shelved this idea following the Model 3’s challenges in its initial production ramp. With an established Gigafactory formula of sorts in its repertoire, however, and coupled with innovations such as the Model Y’s megacasts, Elon Musk’s dreadnoughts may not be too far into the future at all.

Tesla has opened its northernmost Supercharger in Fairbanks, Alaska, with eight V4 stalls located in one of the most frigid cities in the U.S.
Located just 196 miles from the Arctic Circle, Fairbanks’s average temperature for the week was around -12 degrees Fahrenheit. However, there are plenty of Tesla owners in Alaska who have been waiting for more charging options out in public.
There are only 36 total Supercharger stalls in Alaska, despite being the largest state in the U.S.
Eight Superchargers were added to Fairbanks, which will eventually be a 48-stall station. Tesla announced its activation today:

The base price per kWh is $0.43 at the Fairbanks Supercharger. Thanks to its V4 capabilities, it can charge at speeds up to 325 kW.
Despite being the northernmost Supercharger in North America, it is not even in the Top 5 northernmost Superchargers globally, because Alaska is south of Norway. The northernmost Supercharger is in Honningsvåg, Norway. All of the Top 5 are in the Scandanavian country.
Tesla’s Supercharger expansion in 2025 has been impressive, and although it experienced some early-quarter slowdowns due to V3-to-V4 hardware transitions, it has been the company’s strongest year for deployments.
🚨🚨 Tesla Supercharging had a HUGE year, and they deserve to be recognized.

Through the three quarters of 2025, the company has added 7,753 stations and 73,817 stalls across the world, a 16 percent increase in stations and an 18 percent increase in stalls compared to last year.
Tesla is on track to add over 12,000 stalls for the full year, achieving an average of one new stall every hour, an impressive statistic.
Recently, the company wrapped up construction at its Supercharger Oasis in Lost Hills, California, a 168-stall Supercharger that Tesla Solar Panels completely power. It is the largest Supercharger in the world.

Tesla hints toward Premium Robotaxi offering with Model S testing
Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”
Tesla Model S vehicles were spotted performing validation testing with LiDAR rigs in California today, a pretty big switch-up compared to what we are used to seeing on the roads.
Tesla utilizes the Model Y crossover for its Robotaxi fleet. It is adequately sized, the most popular vehicle in its lineup, and is suitable for a wide variety of applications. It provides enough luxury for a single rider, but enough room for several passengers, if needed.
However, the testing has seemingly expanded to one of Tesla’s premium flagship offerings, as the Model S was spotted with the validation equipment that is seen entirely with Model Y vehicles. We have written several articles on Robotaxi testing mules being spotted across the United States, but this is a first:
🚨 Tesla is using Model S vehicles fitted with LiDAR rigs to validate FSD and Robotaxi, differing from the Model Ys that it uses typically

Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”
It seems to hint that Tesla could add a premium, more luxury offering to its Robotaxi platform eventually. Think about it: Uber has Uber Black, Lyft has Lyft Black. These vehicles and services are associated with a more premium cost as they combine luxury models with more catered transportation options.
Tesla could be testing the waters here, and it could be thinking of adding the Model S to its fleet of ride-hailing vehicles.
Reluctant to remove the Model S from its production plans completely despite its low volume contributions to the overall mission of transitioning the world to sustainable energy, the flagship sedan has always meant something. CEO Elon Musk referred to it, along with its sibling Model X, as continuing on production lines due to “sentimental reasons.”
However, its purpose might have been expanded to justify keeping it around, and why not? It is a cozy, premium offering, and it would be great for those who want a little more luxury and are willing to pay a few extra dollars.
Of course, none of this is even close to confirmed. However, it is reasonable to speculate that the Model S could be a potential addition to the Robotaxi fleet. It’s capable of all the same things the Model Y is, but with more luxuriousness, and it could be the perfect addition to the futuristic fleet.

Rivian unveils self-driving chip and autonomy plans to compete with Tesla
Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.
Rivian unveiled its self-driving chip and autonomy plans to compete with Tesla and others at its AI and Autonomy Day on Thursday in Palo Alto, California.
Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.
CEO RJ Scaringe said it will learn and become more confident and robust as more miles are driven and it gathers more data. This is what Tesla uses through a neural network, as it uses deep learning to improve with every mile traveled.
He said:
“I couldn’t be more excited for the work our teams are driving in autonomy and AI. Our updated hardware platform, which includes our in-house 1600 sparse TOPS inference chip, will enable us to achieve dramatic progress in self-driving to ultimately deliver on our goal of delivering L4. This represents an inflection point for the ownership experience – ultimately being able to give customers their time back when in the car.”
At first, Rivian plans to offer the service to personally-owned vehicles, and not operate as a ride-hailing service. However, ride-sharing is in the plans for the future, he said:
“While our initial focus will be on personally owned vehicles, which today represent a vast majority of the miles to the United States, this also enables us to pursue opportunities in the rideshare space.”
The Hardware
Rivian is not using a vision-only approach as Tesla does, and instead will rely on 11 cameras, five radar sensors, and a single LiDAR that will face forward.
It is also developing a chip in-house, which will be manufactured by TSMC, a supplier of Tesla’s as well. The chip will be known as RAP1 and will be about 50 times as powerful as the chip that is currently in Rivian vehicles. It will also do more than 800 trillion calculations every second.

RAP1 powers the Autonomy Compute Module 3, known as ACM3, which is Rivian’s third-generation autonomy computer.
ACM3 specs include:
- 1600 sparse INT8 TOPS (Trillion Operations Per Second).
- The processing power of 5 billion pixels per second.
- RAP1 features RivLink, a low-latency interconnect technology allowing chips to be connected to multiply processing power, making it inherently extensible.
- RAP1 is enabled by an in-house developed AI compiler and platform software
As far as LiDAR, Rivian plans to use it in forthcoming R2 cars to enable SAE Level 4 automated driving, which would allow people to sit in the back and, according to the agency’s ratings, “will not require you to take over driving.”
More Details
Rivian said it will also roll out advancements to the second-generation R1 vehicles in the near term with the addition of UHF, or Universal Hands-Free, which will be available on over 3.5 million miles of roadway in the U.S. and Canada.
More than any other feature, our owners have asked for more hands-free miles.
With Universal Hands-Free, you can now enjoy hands-free assisted driving on any road with clearly defined lanes. That’s roughly 3.5 million miles in the U.S. and Canada.
