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.

Elon Musk has publicly questioned Moody’s credit assessments following the rating agency’s decision to assign SpaceX a Baa1 investment-grade rating, two notches above Tesla’s Baa3. The comments came amid discussions comparing the two companies’ financial profiles.
SpaceX earned its first-time Baa1 rating with a stable outlook from Moody’s. The agency highlighted the company’s leadership in orbital launches, the growing recurring revenue from its Starlink satellite network, strong vertical integration, U.S. government contracts, and emerging opportunities in AI infrastructure.
These factors were cited as supporting robust cash flows, margin expansion, and financial flexibility.
Musk responded directly: “Tesla’s credit rating is ridiculously low tbh,” and added, “Yeah, makes no sense. Tesla has over $40B in cash, no debt, and is consistently profitable!” His remarks underscored Tesla’s balance sheet strength and profitability at a time when many traditional automakers continue to report losses in the shift to electric vehicles.
Yeah, makes no sense.
Tesla has over $40B in cash, no debt and is consistently profitable!
— Elon Musk (@elonmusk) June 19, 2026
Tesla maintains a leading position in the global EV market, with diversification into energy and storage, battery technology, and robotics through projects like Optimus. Recent financial updates show the company generated positive free cash flow of $1.4 billion in Q1 2026, supported by operating cash flow of $3.9 billion. Cash and short-term investments stood at approximately $44.7 billion.
Moody’s has affirmed Tesla’s Baa3 issuer rating with a stable outlook in periodic reviews, acknowledging the company’s EV leadership, technology strengths, including AI for autonomous vehicles, solid profitability, and strong liquidity.

However, the agency has also noted challenges in the automotive segment and expectations for margin pressures.
Musk’s critique highlights a common debate about how traditional rating methodologies apply to high-growth, capital-intensive technology companies. SpaceX benefits from long-term government-backed contracts and diversified, recurring revenue streams, while Tesla’s valuation reflects heavy investment in future technologies such as autonomy and robotics.
Both ratings remain investment-grade, yet the one-notch difference has fueled online discussion about potential inconsistencies in evaluating innovative firms.
The exchange comes as SpaceX explores financing options following its recent valuation milestones, while Tesla continues executing on its multi-year roadmap. Musk’s pointed response serves as a reminder that credit ratings, though influential for borrowing costs, represent one lens through which markets assess corporate strength—and that company leaders often view their financial positions through the lens of long-term innovation and cash generation rather than short-term risk metrics alone.
A new report from Reuters claims that a transport authority in Sweden is pushing back against the approval of Tesla’s Full Self-Driving suite because it will travel over speed limits.
The report says the Swedish Transport Administration (TRV) recommends the European Union votes against FSD’s approval. TRV believes it should not be approved until Tesla disables FSD’s ability to speed.
TRV sent a letter to the European Union’s Technical Committee on Motor Vehicles (TCMV), which is set to meet on June 30 to discuss the potential approval of the Tesla FSD suite in the country. Tesla, which has received various approvals in Europe over the past two months, has not provided a comment.
Teslas operating on FSD do travel over the speed limit, depending on the Speed Profile that is chosen. Drivers have the ability to disengage FSD at any point; Tesla specifically states that those supervising the suite are responsible for its actions.
Let’s cut to the chase: humans operating any vehicle speed almost daily in the United States. Realistically, speed limits in the U.S. are more frequently treated as speed minimums. However, other countries are different, and driving behaviors are less aggressive.
TRV believes that “allowing automated systems to systematically exceed legal speed limits…risks undermining both the legal framework and the expected safety benefits of vehicle automation,” the report stated. It’s surprising that Tesla has not received this claim from other countries previously.
This could be a good argument to bring Max Speed back, the setting that previously allowed the driver to choose the absolute fastest the car would travel.
This would still put the responsibility of supervision in the hands of the driver. It would allow the driver to choose whether the car would travel over the speed limit or not, acknowledging that they set the speed, and if they get pulled over, there would be no ability to argue it.
However, it does not seem as if this is something Tesla will do, especially considering many U.S. drivers have requested the feature in an effort to eliminate speeding or at least tone it down. The company has not shown any interest in bringing it back.
Tesla has approvals for FSD in Europe in Estonia, Lithuania, Denmark, the Netherlands, and Belgium.
Tesla is going to let you guide Full Self-Driving with Grok in 3 months, CEO Elon Musk confirmed on X.
The response from Musk, which revealed Tesla plans to allow drivers to effectively control the car and its navigation more explicitly using Grok, puts the feature for about September.
A Tesla owner said that Full Self-Driving is great, but owners should be able to “converse with Grok like we can with an Uber driver.” She then used examples like, “Grok, turn right here,” and “Drop us off right here, we’ll walk due to traffic,” and finally,” Drop at entrance first, then park far away.”
Coincidentally, the final piece of dialogue would also mean features like Banish are potentially on the way soon.
This functionality will be there in about 3 months or so
— Elon Musk (@elonmusk) June 18, 2026
Banish is also referred to as “Reverse Summon,” and would enable the car to self-park while dropping occupants off at their destination.
This would be a great way to improve the overall experience while supervising FSD. Navigation is already a major painpoint that many owners complain about. Manual overrides when a maneuver is requested or canceled (like using the turn signal stalk to override a navigation route), do not always work.
The feature could be especially useful in street parking scenarios in a city, where spots are sometimes tough to come by. Many of us who grab dinner in a more populated area will park a street or two over from wherever we’re going, because sometimes you know that’s the best you will get. If a driver using FSD could say, “Hey Grok, turn right here on Queen St. and park in that open spot on the right,” it could save a lot of confusion FSD might have on its own.
Musk teased that a similar feature was “coming” back in February:
Tesla Full Self-Driving set to get an awesome new feature, Elon Musk says
It is certainly surprising that Tesla is doing it at this point. The company’s more recent moves have been more evident of taking control and inputs away from humans and putting them in the AI’s hands more frequently. The biggest example of this was taking away Max Speed in AI4 cars, giving us Speed Profiles, and not having any input on the fastest speed the car will travel.
Of course, giving navigation preferences to Grok is availble already in Teslas, but not at the drop of a hat. Instead, you can suggest a certain route at the beginning of your drive.
Here’s an example of that from December:
🚨🏈 I am taking my parents and Fiancee to the @Ravens game next weekend and asked @Grok to help me route my @Tesla through a specific neighborhood to reach the correct Lot we will park in.
This is a great example of the new @grok nav integration with the Tesla Holiday Update: pic.twitter.com/rPp4I7q8Yv
— TESLARATI (@Teslarati) December 13, 2025
Finally, the original post that Musk responded to mentioned a parking preference after dropping off the occupants, which describes the Banish feature that Tesla has teased for years.
We’re not sure if Musk was responding more to the ability to guide the car with Grok, or whether he also was including Banish in the three-month prediction timeframe.
