Tesla integrates Steam into the Model S and Model X
Tesla
Tesla has integrated Steam's library of thousands of games in its Model S and Model X electric vehicles. In July, Elon Musk said that Tesla would release a demo of the Steam integration by August. The demo never came to fruition, but Musk reiterated the plan to integrate Steam into Tesla vehicles. Tesla just launched a beta version of the video game library as part of its holiday update.
Supported Vehicles
For now, Steam is only available on newer versions of the Model S and X with 16GB of ram, but Elon has said that there will be a retrofit available for earlier S and X models in the future.
Although newer Model 3 and Model Y cars have the AMD Ryzen chip, they did not get beta access to Steam because these vehicles do not have a discrete GPU like the Model S and X. It's not clear whether Steam will eventually be integrated into other MCU 3 cars (with a smaller catalog), including the Model 3 and Model Y, but it's unlikely that it'll ever come to any MCU 2 vehicles.
Storage
Games must be downloaded on WiFi and stored locally in the vehicle. This could be in the vehicle's internal drive, which appears to have about an 80GB partition allocated for games or via external storage. The holiday update that added Steam also added support for external storage devices. Additionally, Tesla has released a 1TB SSD that costs $350 and will be available in February 2023. The SSD offers storage for any vehicle data including dashcam footage but is optimized for fast loading. It is also designed to withstand the potentially extreme temperature fluctuations that can occur inside a car and is guaranteed to have a long life span.
However, owners can use almost any solid-state drive they own. In fact, Tesla's own hard drive appears to just be a rebranded Samsung T7 SSD, which is known for its speed and durability. It currently sells on Amazon for less than $140.

Cloud Saves
For games that support Steam Cloud, Tesla will automatically sync your game progress, so that you can pick up right where you left off, regardless if you're at home or in your car.
Premium Connectivity
Tesla's Premium Connectivity allows vehicle owners to access more bandwidth-hungry features such as streaming music and video. Although Steam games are downloaded over WiFi, Tesla requires Premium Connectivity to access Steam. This could be due to Tesla keeping your Steam profile and game process synced.
Rear Display
Unfortunately, Tesla does not currently allow users to play Steam on the vehicle's rear 8" display which can be used to watch streaming video while the car is in motion. Tesla could allow this in a future update, but at the moment Steam is limited to the vehicle's 17" display when the vehicle is in park.
Bluetooth Controllers
Along with Steam support, Tesla has added support for Bluetooth controllers and even keyboard and mouse setups in supported games. Tesla says that PS5 controllers work best with this feature.
In June of 2021, Tesla unveiled a proprietary controller which closely resembled a PS5 controller with two analog sticks, four directional buttons and four action buttons. The controller also resembles a steering wheel with a closed-loop design, likely to accommodate racing games. Since the unveiling, we haven’t heard much about the Tesla controller.

Tesla’s Cybertruck has officially earned a 5-Star Safety Rating from the NHTSA—an impressive achievement given the vehicle’s design. The achievement demonstrates Tesla’s engineering prowess. As one engineer points out, it wasn’t an easy feat.
Interestingly, the NHTSA only recently disclosed the results, despite the crash tests being completed a while ago. According to Lars Moravy, Tesla’s VP of Vehicle Engineering, the team had been aware of the 5-star rating for quite some time. While the reason for the delay remains unclear, now that the results are public, Tesla’s engineers can finally share how they achieved the rating.
Crumple Zones
Wes Morril, the Cybertruck’s Lead Engineer, wrote about the crash test video on X recently, addressing the claims that the Cybertruck doesn’t have a crumple zone. He also posted a side-by-side video (below) of the engineering analysis and the crash test itself.
Engineered Crash Safety
There’s a lot of engineering precision at play when a Cybertruck is involved in a crash. Unlike traditional crash structures that rely on crash cans and collapse points, the Cybertruck’s front gigacasting is designed to absorb and redirect impact forces in a highly controlled manner.
It all starts with the bumper beam, which crushes within the first few milliseconds of a high-speed impact. At the same time, the vehicle’s sensors rapidly analyze the crash dynamics and determine the optimal deployment of safety restraints, including airbags and seat belt pre-tensioners. These split-second actions are crucial in keeping occupants safe.
As the crash progresses, the vehicle’s structure deforms in a carefully engineered sequence. The drive unit cradle bends, directing the solid drive unit downward and out of the way, allowing the gigacasting to begin absorbing impact forces.
The casting crushes cell by cell, methodically dissipating energy in a controlled manner. This gradual deceleration reduces the g-forces transferred to occupants, making the crash much less severe. As the gigacast begins crushing, the safety restraints are deployed.
As Wes points out in his post - you can see how accurate the virtual analysis and modeling were. The video shows the simulated crash side by side with the real-life crash test and they’re almost identical. All that virtual testing helps provide feedback into the loop to design a better and safer system - one that is uniquely different than any other vehicle on the road.
All the armchair experts claimed the Cybertruck has no crumple zone and I get it, the proportions seem impossible. It was a tough one and there is a lot of engineering that went into it. Let me break it down for you:
Tesla has pioneered the use of single-piece castings for the front and rear sections of their vehicles, thanks to its innovative Gigapress process. Many automakers are now following suit, as this approach allows the crash structure to be integrated directly into the casting.
This makes the castings not only safer but also easier to manufacture in a single step, reducing costs and improving repairability. For example, replacing the entire rear frame of a Cybertruck is estimated to cost under $10,000 USD, with most of the expense coming from labor, according to estimates shared on X after high-speed rear collisions.
These insights come from Sandy Munro’s interview (posted below) with Lars Moravy, Tesla’s VP of Vehicle Engineering, highlighting how these advancements contribute to the improvements in Tesla’s latest vehicles, including the New Model Y.
However, with the new Model Y, Tesla has decided to go a different route and eliminated the front gigacast.
No Front Casting
Tesla’s factories aren’t equipped to produce both front and rear castings for the Model Y. Only Giga Texas and Giga Berlin used structural battery packs, but these were quickly phased out due to the underwhelming performance of the first-generation 4680 battery.
Tesla has gone back to building a common body across the globe, increasing part interchangeability and reducing supply chain complexity across the four factories that produce the Model Y. They’ve instead improved and reduced the number of unique parts up front to help simplify assembly and repair.
There is still potential for Tesla to switch back to using a front and rear casting - especially with their innovative unboxed assembly method. However, that will also require Tesla to begin using a structural battery pack again, which could potentially happen in the future with new battery technology.
Rear Casting Improvements
The rear casting has been completely redesigned, shedding 7 kg (15.4 lbs) and cutting machining time in half. Originally weighing around 67 kg (147 lbs), the new casting is now approximately 60 kg (132 lbs).
This 15% weight reduction improves both vehicle dynamics and range while also increasing the rear structure’s stiffness, reducing body flex during maneuvers.
Tesla leveraged its in-house fluid dynamics software to optimize the design, resulting in castings that resemble organic structures in some areas and flowing river patterns in others. Additionally, manufacturing efficiency has dramatically improved—the casting process, which originally took 180 seconds per part, has been reduced to just 75 seconds, a nearly 60% time reduction per unit.

Tesla’s new casting method incorporates conformal cooling, which cools the die directly within the gigapress. Tesla has been refining the die-casting machines and collaborating with manufacturers to improve the gigapress process.
In 2023, Tesla patented a thermal control unit for the casting process. This system uses real-time temperature analysis and precise mixing of metal streams to optimize casting quality. SETI Park, which covers Tesla’s manufacturing patents on X, offers a great series for those interested in learning more.
The new system allows Tesla to control the flow of cooling liquid, precisely directing water to different parts of the die, cooling them at varying rates. This enables faster material flow and quicker cooling, improving both dimensional stability and the speed of removing the part from the press for the next stage.
With these new process improvements, Tesla now rolls out a new Model Y at Giga Berlin, Giga Texas, and Fremont every 43 seconds—an astounding achievement in auto manufacturing. Meanwhile, Giga Shanghai operates two Model Y lines, delivering a completed vehicle every 35 seconds.
