UPDATE: Tesla Cybertruck steel supplier’s Sinton, TX plant to start initial operations next month
Correction: A message sent to Teslarati has confirmed that Steel Dynamics Inc. is not Tesla’s supplier for the Cybertruck’s steel. With regards to the Cybertruck’s supply chain, Steel Dynamics will aspire to work towards becoming an approved supplier to Tesla.
***Original article follows***
Steel Dynamics Inc. (SDI), Tesla’s steel supplier for the Cybertruck’s exoskeleton, is expected to start initial operations in its Sinton, Texas facility next month. The update was shared to local media by Dennis Black, the General Manager of SDI’s Sinton site.
The Sinton site is a 1.2-million-square-foot facility that is packed with innovative technologies. The steel that would be produced in the Sinton site would be quite environmentally-friendly as well. As noted in a report from 3News, the steel mill features machines that could turn scrap metal into rolled steel that could be used for various commercial purposes.
Black explained that the facility would be using about 90% scrap metal, which, in turn, becomes rolls of steel that could be sold to clients. Among SDI’s clients is Tesla, which has made Texas its headquarters. “We do start with scrap metal, probably 90% scrap. There may be some alternative irons that we do use to try and make the purification a little bit better, but overall 90% scrap,” Black remarked.
While Steel Dynamics’ Sinton, TX plant is poised to begin initial operations next month, there is still a lot of work to be done in the complex. The company is currently building another 300,000-square-foot building on the site after it realized that it needed more space. So far, about $1.9 billion have been invested in the Sinton facility, which is estimated to have about 700 employees when it is operational.
The Steel Dynamics Sinton plant is located just about 167 miles away from Tesla’s Gigafactory Texas, which should make the transportation of steel between the two facilities fairly straightforward. Interestingly enough, previous comments from San Patricio County Judge David Krebs have hinted that Tesla would “redoing” the steel that it would be receiving from SDI, at least before the material could be used for the Cybertruck’s exoskeleton.
“Now some of these other companies who work with SDI will actually be taking SDI’s product and refining it a little bit better. We’re hearing that one of the companies that were pretty close to–probably getting close–is a company that’s going to be taking SDI steel, redoing it, and that steel will actually be going into the Tesla cars that they’re moving in from California to manufacture here,” the judge previously said.
While recent reports have suggested that the Cybertruck’s initial production would be around Q1 2023, development on the all-electric pickup truck seems to be going at a fair pace. Amidst sightings of updated prototypes in California, Tesla CEO Elon Musk has stated that he would be giving a product roadmap update later this month when the company holds its Q4 and FY 2021 earnings call.

Tesla inks multi-billion-dollar deal with LG Energy Solution to avoid tariff pressure
Tesla has reportedly secured a sizable partnership with LGES for LFP cells, and there’s an extra positive out of it.

Tesla has reportedly inked a multi-billion-dollar deal with LG Energy Solution in an effort to avoid tariff pressure and domesticate more of its supply chain.
Reuters is reporting that Tesla and LGES, a South Korean battery supplier of the automaker, signed a $4.3 billion deal for energy storage system batteries. The cells are going to be manufactured by LGES at its U.S. factory located in Michigan, the report indicates. The batteries will be the lithium iron phosphate, or LFP, chemistry.
Tesla delivers 384,000 vehicles in Q2 2025, deploys 9.6 GWh in energy storage
It is a move Tesla is making to avoid buying cells and parts from overseas as the Trump White House continues to use tariffs to prioritize domestic manufacturing.
LGES announced earlier today that it had signed a $4.3 billion contract to supply LFP cells over three years to a company, but it did not identify the customer, nor did the company state whether the batteries would be used in automotive or energy storage applications.
The deal is advantageous for both companies. Tesla is going to alleviate its reliance on battery cells that are built out of the country, so it’s going to be able to take some financial pressure off itself.
For LGES, the company has reported that it has experienced slowed demand for its cells in terms of automotive applications. It planned to offset this demand lag with more projects involving the cells in energy storage projects. This has been helped by the need for these systems at data centers used for AI.
During the Q1 Earnings Call, Tesla CFO Vaibhav Taneja confirmed that the company’s energy division had been impacted by the need to source cells from China-based suppliers. He went on to say that the company would work on “securing additional supply chain from non-China-based suppliers.”
It seems as if Tesla has managed to secure some of this needed domestic supply chain.

Tesla brings perhaps the coolest interior feature to cars in latest update
Tesla adds on to the “fun” aspect of its vehicles.

Tesla has brought perhaps the coolest interior feature to its cars in a new update that is rolling out to vehicles now.
The feature will require a newer vehicle that has interior ambient lighting, which is present on the new Model S, Model X, Model 3 “Highland,” and Model Y “Juniper.” The Cybertruck also has ambient lighting strips throughout.

With the Version 2025.26+ Software Update, Tesla is rolling out a new “Sync Accent Lights w/ Music” feature, which is available on the Tesla Toybox:

To enable the feature, you’ll access the Toybox, choose “Light Sync,” and then choose “Sync Accent Lights w/ Music.”
Although it does not improve the performance of the vehicle, it is yet another example of Tesla making one of the coolest cars out there. This is truly a cool add-on that can be used to impress your friends and family.

Tesla uses Sydney Sweeney ad controversy to flex its car seat testing strategy
Tesla says its seat robot also has great jeans, just like Sydney Sweeney.

Tesla has a knack for making light of a situation. As tensions seem to be high over American Eagle’s latest jeans ad featuring Hollywood it girl Sydney Sweeney, the automaker saw it as a grand opportunity to show off its seat testing.
Tesla builds and does quality control on its own car seats, and they have been built at a factory just down the street from the Fremont Factory for some time. It also performs quality testing in-house.

Outside of the Tesla world, there is a strange controversy going on with Sydney Sweeney and her recent ad for American Eagle, where she describes her “good jeans.” Some see it as a commercial for jeans, others see it as something else, perhaps a political statement of some sort by the clothing maker.
Nevertheless, Tesla is making light of the joke and using it as a chance to show off its in-house seat testing, stating, “Our seats robot also has great jeans.”
Here’s the post:

Tesla went on to refer to the robot as “Sydney Seatney.”
It is nice to see some companies still have a sense of humor, and as the controversy over a seemingly innocuous ad for a pair of jeans continues to rage on, it will be interesting to see who comes after Tesla for this one. It will obviously draw some attention.
The video here is actually from 2019, and not from recently. The robot and machine used in this testing phase simulate long-term use. This is one of the most crucial testing processes the seats go through during the quality assurance phase.
