Reported Tesla supplier Saueressig Engineering plans to establish a facility in San Antonio’s East Side—about 80 miles away from Gigafactory Texas. Saueressig is a division of Matthews International Corp. and may be linked to Tesla’s 4680 battery cell initiatives.

On April 1st, the San Antonio City Council approved an economic incentive package that gave Saueressig a 75% tax abatement on a property located in Profit Drive. According to the official tax abatement agreement, Matthews must invest $9 million in property improvements to avail of the incentive package.

Saueressig Engineering was linked to Tesla when it hinted at a major order from an American automobile manufacturer. According to its official website, Saueressig focuses on “special machine construction” for several industries, including the battery sector.

Previous reports have suggested that Saueressig could be involved in making machines for Tesla’s battery cell production lines for Giga Texas and Giga Berlin. Tesla plans to produce its 4680 cells in its new Gigafactories. Tesla’s 4680 cells will be essential to larger vehicles like the Cybertruck and Semi in the United States, as well as the Made-in-Germany Model Y.

In 2019, the Fraunhofer Institute for Material and Beam Technology IWS shared that it partnered with companies such as Saueressig Engineering to develop a dry electrode coating process for EV batteries.

Fraunhofer IWS started developing a new production process for batteries that coated electrodes with dry film instead of liquid chemicals. Fraunhofer IWS project manager Dr. Benjamin Schumm noted that dry coating would reduce process costs in electrode coating.

“Our transfer process for dry coating aims to noticeably reduce process costs in electrode coating. This means that manufacturers can do without toxic and expensive solvents and save energy costs during drying. In addition, with our technology, electrode materials can also be used that can hardly or not at all be processed wet-chemically,” Dr. Schumm said.

Tesla executives such as Elon Musk and Jerome Guillen have noted in the past that Gigafactory Berlin and Gigafactory Texas would be home to their own 4680 battery cell production facilities. Considering that Tesla’s 4680 cells would utilize dry electrode technology, Saueressig Engineering’s upcoming Texas site would likely be invaluable for Tesla’s operations in the Lone Star state.

Tesla Robotaxi rival Waymo confirms massive fleet expansion in Bay Area

New data from the California Public Utilities Commission (CPUC) said Waymo had 1,429 vehicles operating in California, and 875 of them were “associated with a terminal in San Francisco,” according to The SF Examiner.

Tesla Robotaxi rival Waymo has confirmed that it has expanded its fleet of driverless ride-sharing vehicles in the Bay Area of California massively since its last public disclosure.

It is perhaps one of the most important metrics in the race for autonomous supremacy, along with overall service area. Tesla has seemed to focus on the latter, while expanding its fleet slowly to maintain safety.

Waymo, on the other hand, is bringing its fleet size across the country to significant levels. In March, it told The SF Examiner that there were over 300 Waymos in service in the San Francisco area, which was not a significant increase from the 250 vehicles on the road it reported in August 2023.

In May, the company said in a press release that it had more than 1,500 self-driving Waymos operating nationwide. More than 600 were in the San Francisco area.

However, new data from the California Public Utilities Commission (CPUC) said Waymo had 1,429 vehicles operating in California, and 875 of them were “associated with a terminal in San Francisco,” according to The SF Examiner.

CPUC data from March 2025 indicated that there were a total of 1,087 Waymo vehicles in California, with 762 located in San Francisco. Some were test vehicles, others were deployed to operate as ride-sharing vehicles.

The company’s August update also said that it deploys more than 2,000 commercial vehicles in the United States. That number was 1,500 in May. There are also roughly 400 in Phoenix and 500 in Los Angeles.

While Waymo has done a good job of expanding its fleet, it has also been able to expand its footprint in the various cities it is operating in.

Most recently, it grew its geofence in Austin, Texas, to 90 square miles. This outpaced Tesla for a short period before the company expanded its Robotaxi service area earlier this week to roughly 170 square miles.

The two companies have drastically different approaches to self-driving, as Waymo utilizes LiDAR, while Tesla relies solely on cameras for its suite. Tesla CEO Elon Musk has made no mistake about which he believes to be the superior solution to autonomy.

Tesla has launched its Full Self-Driving suite in a new region, marking a significant step in the company’s progress to expand its driver assistance suite on a global scale.

It is also the first time Tesla has launched FSD in a right-hand-drive market.

Today, Tesla launched Full Self-Driving in Australia for purchase by car buyers for $10,100, according to Aussie automotive blog Man of Many, which tried out the suite earlier this week.

Previously, Basic and Enhanced Autopilot suites were available, but the FSD capability now adds Traffic Light and Stop Sign Control, along with all the features of the previous two Autopilot suites.

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:

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.
