Tesla is planning to expand its Model Y production lines at the Fremont facility located in Silicon Valley, California.
According to two applications that were spotted on Fremont’s Public Access website, there are several planned advancements of “General Assembly 4.5,” which has been designated for Model Y production at the production facility.
In the past, GA 4.5 was also responsible for the production of the Model 3 sedan in late 2018. GA 4.5 is effectively an outdoor tent that Tesla placed outside of the main building. It currently holds five production lines, with the most recent being installed in September 2019. Tesla planned to expand GA 4.5 in April 2020 but had to find solutions to handle stormwater drainage.
The applications are named “4.5 Expansion Rev 1” and “F20-0048-F DCM2 Arch & MEP.” DCM2 could refer to a second die-cast machine in GA 4.5 that will allow the Model Y to be manufactured with a single-piece casting design.
“The current version of Model Y has basically two big high-pressure die-cast [HPDC] aluminum castings that are joined, and there’s still a bunch of other bits that are attached. Later this year. We’ll transition to the rear underbody being a single-piece casting that also integrates the rear crash rails,” CEO Elon Musk said earlier this year.

It was reported in early June that Tesla was planning to purchase the massive “Giga Press” for Model Y production. But now, the name of the application seems to infer that Tesla is planning to install a second die-cast machine for the Model Y to increase production volume.
Additionally, the F20-0048-F DCM2 Arch & MEP application shows Tesla’s planned expansion of a new “canopy structure” that will connect to the main assembly building.
The expansion is broken down into Mechanical, Process, and Controls.
Mechanical
“Process cooling water & natural gas piping distribution design from existing ab utility mains to new casting area outside. Industrial water to serve process equipment. New cooling tower & distribution pump added to existing ab cooling tower yard.”
Process
“Installation of soft water system with distribution piping & accessories. Installation of new compressed air header with filters, distribution & accessories. Installation of new argon and nitrogen distribution with accessories. Installation of new trade waste piping from the tie point inside the building to dcm2 area with pipes, pumps & accessories.”
Controls
“Installation of new sensors on chilled water lines to monitor & control process Installation & networking of new VFD’s to provide control of cooling tower.”

Tesla is preparing for a massive push of the Model Y crossover as demand for the company’s vehicles continues to increase. After delivering 90,650 cars in Q2 2020, the next step is to begin increasing production and delivery figures to sustain growth and increase the consecutive streak of profitable quarters for the electric automaker.
In early June, Musk indicated via email to Fremont employees that the company needed to continue to increase the production of the Model Y by stating that rectifications were to be minimized and that everyone’s effort was appreciated. “I want you to know that it really makes a difference to Tesla right now,” the Tesla frontman said in the email.
After ditching the plans to produce the Standard Range Model Y due to range deficiencies, Tesla can focus on the Long Range and Performance configurations of the vehicle, which have been widely popular within the community thus far.
Tesla’s Long Range and Performance Model Y variants are available for $49,990 and $59,990 respectively.

It is the first time Tesla has launched the suite by name in a region outside of North America. In China, Tesla has “City Autopilot,” as it was not permitted to use the Full Self-Driving label for regulatory reasons.
However, Tesla still lists Full Self-Driving (Supervised) as available in the U.S., Canada, China, Mexico, and Puerto Rico.
The company teased the launch of the suite in Australia earlier this week, and it appeared to have been released to select media members in the region earlier this week:

The rollout of Full Self-Driving in the Australian market will occur in stages, as Model 3 and Model Y vehicles with Hardware 4 will receive the first batch of FSD rollouts in the region.
TechAU also reported that “the initial deployment of FSDs in Australia will roll out to a select number of people outside the company, these people are being invited into Tesla’s Early Access Program.”
Additionally, the company reportedly said it is “very close” to unlocking FSD in customer cars:

Each new Tesla sold will also come with a 30-day free trial of the suite.
Australia is the sixth country to officially have Full Self-Driving available to them, following the United States, Canada, China, Mexico, and Puerto Rico.
Here’s the first look at the suite operating in Australia:

Tesla AI6 chips will start sample production at surprising Samsung site
AI6 is expected to be used in Tesla’s expanding lineup of high-volume products, such as the Cybercab and Optimus.

It appears that the initial sample production of Tesla’s next-generation AI6 chip would not start in Samsung’s United States-based facilities.
AI6 is expected to be used in Tesla’s expanding lineup of high-volume products, such as the Cybercab and Optimus.
Early AI6 production
As noted in a ZDNet Korea report, the production of initial samples of Tesla’s AI6 chip is expected to start at Samsung Electronics’ domestic foundry and packing facilities in South Korea. Mass production for AI6 chips will follow at the tech giant’s Texas-based foundry in Taylor, which is expected to start operations in 2025. Investment in mass production facilities for the Taylor plant are expected to start this year, the publication noted.
Samsung has reportedly finalized the process design kit for its second-generation 2nm technology. This node offers a 12% performance improvement, 25% lower power consumption, and an 8% reduction in chip area compared to its previous-generation counterparts.
Tesla’s AI6 deal
As per previous reports, Tesla has signed a $16.5 billion contract with Samsung for the production of its AI6 chips. In a post on social media platform X, Musk clarified that $16.5 billion is actually just the bare minimum. Considering that the demand for AI6 chips will be substantial due to the ramp of products such as Optimus and the Cybercab, it would not be farfetched if the deal becomes notably larger in the future.
Musk has shared his excitement for Samsung’s production of AI6 chips, with the CEO stating on X that he would “walk the line personally” in the facility to “accelerate the pace of progress.” In a follow-up comment, the Tesla CEO stated that Samsung is fully aware of what a real partnership with Tesla will be like. “I had a video call with the chairman and senior leadership of Samsung to go over what a real partnership would be like. Use the strengths of both companies to achieve a great outcome,” Musk wrote in his post.

Elon Musk’s Boring Company begins Tesla FSD testing in Las Vegas tunnels
The update was shared by Las Vegas Convention and Visitors Authority (LVCVA) CEO Steve Hill.

The Boring Company has started testing Tesla’s Full Self-Driving (Supervised) system in its Las Vegas tunnels.
The update was shared by Las Vegas Convention and Visitors Authority (LVCVA) CEO Steve Hill in a comment to Fortune.
Controlled FSD testing
In his comments, Hill noted that Tesla’s FSD tests in the Boring Company’s underground tunnels in Las Vegas have been going on for months. However, the full-self driving Teslas have reportedly not been carrying passengers during the tests. Interestingly enough, Hill noted that the FSD-driven vehicles have not had any incidents in the Boring Company tunnels yet, though safety drivers have been required to intervene “periodically.”
Hill further noted that the self-driving Teslas have found some spots that seem quite difficult in the underground tunnels system. The LVCVA CEO added that the rock walls of the Boring Company tunnels and their colorful lighting have created some “interesting but odd lighting” for FSD. That being said, Hill noted that the FSD tests are ongoing, though the LVCVA will likely be a consultant before the self-driving vehicles’ safety drivers are removed.
The executive, however, noted that it will only be a matter of time before the Teslas in Las Vegas’ Boring Company tunnels are operating without a driver. “Sooner or later, this is going to be autonomous,” Hill said.
Vegas Loop updates
The Boring Company’s underground transit system has been operating beneath the Las Vegas Convention Center for about four years. While the network is slated for expansion across more of the city, it currently connects the convention grounds with a handful of nearby hotels. Updates from the Boring Company’s official social media account on X suggests that tunneling is underway across other stops in Las Vegas.
As per the Boring Company on its official website, the greater Vegas Loop, when completed, will have 104 stations across 68 miles of tunnels. This should allow the underground system to serve an estimated 90,000 passengers per hour. It will also be able to connect key locations across the city, such as Harry Reid International Airport, Allegiant Stadium, and downtown.
While the Vegas Loop is nowhere near complete, Hill noted that the system is already well appreciated by residents and visitors. As per the LVCVA CEO, the underground transport system is the “highest rated feature we have” at the Convention Center. “People love it,” he said, adding that the only reason the tunnels are not coming faster is due to holdups with permits. “We’re holding them back. They’re not holding us back,” he stated.
