It appears that Tesla’s rear casting and structure improvements for the Model Y have been designed to improve the safety of passengers who will occupy the vehicle’s future third row of seats.
As Sandy Munro continues to dive into the company’s new all-electric crossover, several clues hint toward the vehicle’s improved rear safety design. Munro mentions multiple design improvements that range from thicker longitudinal bars to prevent crunching in the even of an accident, to new bolt shapes that decrease weight and improve durability.
Munro first looks at the castings on the side rails of the Model Y. The attachment points on each side of the car indicate they are one piece and are not welded on. “They’re plenty strong, and you can see they’re just cast in place,” he said. Also, the under-seat points are 3 to 3.5mm thick. Munro suggests Tesla moved added density to other areas that may be more susceptible to being compromised in an accident. “There is a lot of good stuff here. I like that.”
According to Munro, Model Y has improved fixture points on the rear longitudinals that run from the front to the back of the car. While the two bolts on the front of the longitudinals are standard, the top bolt on the rear end is scooped out. “These are common on Japanese cars. See how it’s dished out? The Japanese use this for weight reduction, but it is also good for a shear bolt. So my guess is this may be something to do with crashworthiness,” Munro said.
Shear bolts are commonly used to protect equipment from sudden impact or excessive load. They are often referred to as “anti-theft bolts” and popular among assemblies that may be subjected to occurrences of excessive force. However, they are ideal for safety and an accident would maintain the structural integrity of the rear portion of the car, keeping those seated in the back safe from injury during a violent collision.

Speculation from the Detroit veteran suggests the Model Y’s third row of seats will be rear-facing, especially as the design of the mounting brackets only leads Munro to believe that the sixth and seventh passengers will be looking out of the vehicle’s rear windshield.
“We can’t see anything that says that we’re going to be putting front-facing seats. But, we sure can see where it could be a potential there for rear-facing seats,” Munro said.
A video Munro posted on April 4 to the company YouTube channel examined the Model Y’s potential for rear-facing third-row seats. Munro hopped into the trunk of the crossover and was impressed by the size and spaciousness, and mentioned that it was “semi-comfortable” and may be best for children based on its storage design.
Based on what is known about Tesla’s previous and upcoming third-row seating options, the design would likely be rear-facing. Jump seats in the Model S were popular among the sedan’s owners before the release of the Model X. Additionally, the upcoming release of the Plaid Mode Model S will include rear-facing jump seats that will support larger passengers instead of just children.
The Model Y was always aimed toward being the safest midsize SUV on the road. With the inclusion of an optional third row of seats, the Model Y’s rear collision safety had to be revamped and rejuvenated. The addition of shear bolts for durability and increased thickness in some areas for added strength was likely added to improve the safety of third-row passengers in an accident.

Tesla watchers spot mysterious castings at Fremont Factory
The castings seem to be quite new, as they do not seem to match any of the castings that are currently being used for the Model Y.

A recent flyover of the Fremont Factory has triggered speculations about Tesla’s ongoing initiatives that are yet to be unveiled publicly. This was hinted at by the sighting of some apparent vehicle castings around the factory that have never really been observed before.
A Fremont Factory flyover
In a recent update, drone operator Met God in Wilderness, who has been chronicling the progress and developments of the Fremont Factory for years, shared some footage from his August 14, 2025 flyover. Based on the video, the Fremont Factory seemed very much alive. Vehicles were being pumped out of the factory, and a rather interestingly covered car could be seen going around the test track.
What is quite fascinating about the footage from the Fremont Factory is the fact that the vehicles that were moving from the production line to the outbound logistics lot are not driven manually anymore. As per Tesla in previous updates, vehicles produced at the Fremont Factory navigate to the outbound logistics lot on their own using Unsupervised FSD.
Mysterious castings
Perhaps most interestingly, the drone operator also managed to capture some footage of some castings that were being gathered just outside one of the facility’s sprung structures. These castings seem to be quite new, as they do not seem to match any of the castings that are currently being used for the Model Y. This has brought speculations suggesting that the new components, which seem smaller than standard Model Y megacasts, may be for a different, perhaps more compact, vehicle.
As per Tesla in its second quarter earnings call, the company actually started the initial production of more affordable models sometime in June. These vehicles, as per Elon Musk, will be made available for consumers in the fourth quarter. “Given that we started in North America and that our goal is to maximize production with higher rates by the end of Q3, we’re going to keep pushing hard on our current models to avoid complexity… We’ll be running with the more affordable models available for everyone in Q4,” Musk said.

Shareholder group urges Nasdaq probe into Elon Musk’s Tesla 2025 CEO Interim Award
The SOC Investment Group represents pension funds tied to more than two million union members, many of whom hold shares in TSLA.

An investment group is urging Nasdaq to investigate Tesla (NASDAQ:TSLA) over its recent $29 billion equity award for CEO Elon Musk.
The SOC Investment Group, which represents pension funds tied to more than two million union members—many of whom hold shares in TSLA—sent a letter to the exchange citing “serious concerns” that the package sidestepped shareholder approval and violated compensation rules.
Concerns over Tesla’s 2025 CEO Interim Award
In its August 19 letter to Nasdaq enforcement chief Erik Wittman, SOC alleged that Tesla’s board improperly granted Musk a “2025 CEO Interim Award” under the company’s 2019 Equity Incentive Plan. That plan, the group noted, explicitly excluded Musk when it was approved by shareholders. SOC argued that the new equity grant effectively expanded the plan to cover Musk, a material change that should have required a shareholder vote under Nasdaq rules.
The $29 billion package was designed to replace Musk’s overturned $56 billion award from 2018, which the Delaware Chancery Court struck down, prompting Tesla to file an appeal to the Delaware Supreme Court. The interim award contains restrictions: Musk must remain in a leadership role until August 2027, and vested shares cannot be sold until 2030, as per a Yahoo Finance report.
Even so, critics such as SOC have argued that the plan does not have of performance targets, calling it a “fog-the-mirror” award. This means that “If you’re around and have enough breath left in you to fog the mirror, you get them,” stated Brian Dunn, the director of the Institute for Comprehension Studies at Cornell University.
SOC’s Tesla concerns beyond Elon Musk
SOC’s concerns extend beyond the mechanics of Musk’s pay. The group has long questioned the independence of Tesla’s board, opposing the reelection of directors such as Kimbal Musk and James Murdoch. It has also urged regulators to review Tesla’s governance practices, including past proposals to shrink the board.
SOC has also joined initiatives calling for Tesla to adopt comprehensive labor rights policies, including noninterference with worker organizing and compliance with global labor standards. The investment group has also been involved in webinars and resolutions highlighting the risks related to Tesla’s approach to unions, as well as labor issues across several countries.
Tesla has not yet publicly responded to SOC’s latest letter, nor to requests for comment.
The SOC’s letter can be viewed below.

Tesla Model Y L has two distinct features for luxurious comfort
This is not to say the other interior additions are not factors in the Model Y becoming a more luxurious and premium vehicle, but the two mentioned in this article are particularly pertinent in that conversation.

Tesla’s new Model Y L has two distinct features that are geared toward giving occupants a taste of luxury with guaranteed comfort.
These two features should definitely be part of the company’s future lineup, and they could prove to be massive upgrades to the Model Y’s interior, which is certainly premium but is missing some things that truly tailor to a “luxury” feel of an automobile.
This is not to say the other interior additions are not factors in the Model Y becoming a more luxurious and premium vehicle, but the two mentioned in this article are particularly pertinent in that conversation.
Tesla Model Y L might not come to the U.S., and it’s a missed opportunity
Power-Adjustable Thigh Supports
In the front seats of the Model Y L, there are power-adjustable thigh supports that will enable some additional comfort on the legs:

Most might think that these thigh supports are simply a feature that makes the ride more comfortable, which is true. However, they have benefits for the ride and after you exit the car.
Providing proper lift on the legs and thighs can be beneficial for people with back problems or posture issues. The lower back takes an increased amount of stress during long car rides, especially as the legs are fixed in the chosen seating position.
Tesla Model Y L officially launched: price, features, and more
Adding some support to the thighs can help reduce pressure on the lower back and hips, and distribute weight more evenly, taking stress off pressure points.
It can also contribute to better spinal alignment. They also have safety benefits, as some riders could have an improved seatbelt position thanks to the thighs being in this position.
Second-Row Mechanical Armrest
Tesla also added mechanical, one-touch armrests to the Model Y L’s second row, a nice and premium touch for the riders in the middle of the vehicle:

Add the additional space the Model Y L provides to riders, and it already gets more comfortable. However, the addition of the mechanical armrests gives a good option of comfort for those who are seated in the second row.
They can also be retracted with the touch of a button, allowing for those in the third row to exit the vehicle easily.
One con to the mechanical portion of these armrests is that it is another moving part, and, of course, that puts it at risk of having issues.
However, it is certainly more premium than a manual armrest, and the flashy carbuyers will appreciate this small but mighty addition.
