Tesla is expected to move the Model 3 and Model Y to a steering wheel with touch-sensitive buttons
Tesla
According to Twitter user @ChrisZheng001, who has ties with the Tesla supply chain in China, the Model 3 and Model Y will be receiving a new steering wheel for the 2023 model year.
The new steering wheel will supposedly follow what has already been done with the new Model S; replacing the steering wheel stalks with touch-sensitive buttons on the steering wheel.
In a Model 3 or Model Y, the left stalk is mainly used for the vehicle's turn signals, but it can also be used to activate or flash the car's high beams. The button at the end of the stalk brings up the windshield wiper controls and wipes the windshield a single time.
As for the right stalk, it's used to shift gears, enable Autopilot and put the vehicle into park. The button can also be used to enable the vehicle's emergency brake by holding it down.
In the Model S, which the Model 3 and Model Y are likely to mimic, these functions are moved to the steering wheel and the touch screen.
The steering wheel will likely be similar to the one in the Model S. However, it'll likely be round since a major advantage of having a yoke steering wheel is to have a better view of the instrument cluster.
The upcoming steering wheel may be the one that's featured in the new Tesla Semi photos.
Like the Model S, the touch-sensitive buttons wrap around the outside of the scroll wheels on the steering wheel.
On the left side, you have the turn signals and high beam buttons, while on the right you have buttons for the windshield wipers and voice commands. On the Model 3, clicking the right scroll wheel starts a voice command, but in the Model S that's used to engage Autopilot.
There is also a button for the horn, however, unlike earlier versions of the Model S, the center of the steering wheel also functions as a horn.
Other functions that were previously available on the steering wheel stalks, such as shifting gears are moved to the center touch screen.
Since the buttons and their designs are fixed, you can't customize these buttons nor can Tesla change them through software updates.
I'd love to have seen tiny OLED screens for these buttons, similar to the Optimus keyboard that has a tiny screen for each key. That would leave room for customization or change down the road, although it would come at a cost and introduce additional complexity. Two things Tesla tries hard to reduce.
It's not clear whether existing vehicles with steering wheel stalks will also gain the ability to swipe to shift, but it's possible since Tesla could use the existing steering wheel stalks as a backup solution if the touch screen isn't working.
The backup solution in the Model S and likely future Model 3s and Model Ys are touch-sensitive gear buttons that appear underneath the wireless phone charger if the touch screen becomes unresponsive.
This upcoming change may be unexpected, but it's not surprising, as Tesla often tries to reduce costs by simplifying designs and processes. Tesla also tries to reuse as many parts throughout their models as possible. While the Model S and Model X use a different steering wheel, it looks like the Semi may utilize the same steering wheel as the Model 3 and Model Y.

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.
