Tesla owners who are dog lovers no longer have to decide between Sentry Mode and Dog Mode. That is just one of several enhancements in the latest update — 2022.40.1.
Other improvements include battery preconditioning, driver door unlock and radio station logos, while existing features have launched in new regions.
New Features
Let's start with the Sentry and Dog Mode combo. Both of these features would rate high on items that Tesla owners appreciate about their vehicles. Sentry is a best-in-class security/surveillance system, and Dog Mode keeps the cabin at an appropriate temperature for your pet while you are away.
However, the two systems did not work together because Sentry would constantly be triggered whenever the dog moved inside the vehicle. For those who have dogs that love car rides, this meant not being able to use Sentry to protect your car and your dog. Now both features can be used together for most vehicles. This update silences Sentry Mode alarms while still recording and keeping the temperature safe for your pooch.
Listening to the radio may get more appealing with the addition of radio station logos to the media player.
The radio in a Tesla doesn't get a lot of recognition since competes against music streaming services and other entertainment that have much more engaging screens, but Tesla did a great job with its radio implementation.
The radio will automatically scan for local stations, so you can just tap to get to your favorite station. It also offers a direct input instead of a radio dial and now features radio station icons to make it easier to find your favorite station. With this update the list of radio stations has been changed to a grid to make room for the station name and logo. When playing an FM radio station, the station's logo will also appear in the album artwork area of the music player. (Photo credit to ArsalamiSandwich).

Voice directions are now available in Hebrew in the Middle East. Tesla continues to expand the languages offered in its vehicles. It's estimated that 9 million people speak Hebrew worldwide.
Improvements to Existing Features
In an effort to speed up charging times, the thermal system control will now be optimized to match the charging station's power capability. The company has been expanding its vast network of Superchargers, which means there are many variations in the station output. This update means your Tesla won't waste too much energy preparing the battery if you're headed to a slower DC charging station.
Update 2021.44 added the ability to only unlock the driver's door when the handle is pressed to improve safety. However, it wasn't ideal when traveling with passengers as they would have to wait until you get into the vehicle to open the other doors.
With update 2022.40, Tesla did what it does best — improve vehicle features. If you have the Driver Door Unlock Mode feature on, you can now hold and press the interior driver door switch to unlock all vehicle doors and trunk.
If this update Tesla is also adding this feature to the new Model S.
To access Driver Door Unlock Mode, tap Controls > Lock > Driver Door Unlock Mode.
More vehicles and regions now have access to a consistent regenerative braking feel even when it's limited. For example, regenerative braking may not be available when the battery is at a max charge or in certain weather conditions. In May 2022, Tesla sent out an update to many areas and vehicles, allowing the car to behave the same way when it is decelerating with or without regenerative braking. This feature enables drivers to perfect the one-foot driving technique at all times.
With this update, it is now available for some legacy Model S and Model X vehicles.
With winter coming, the Tire Configuration program is now for the Model Y as well. It allows users to reset the learned tire settings after a tire rotation or replacement for an improved driving experience. To reset, tap Controls > Service > Wheel & Tire Configuration > Tires.
Other changes include exterior lighting improvements and Sentry Mode Live Camera Access added to Israel, Supercharger details included in China, and Boombox is now available in Japan. However, Hong Kong went against the trend as it continues to allow fewer features. The dashcam viewer has been removed, the country recently took away Tesla's arcade and Toybox.
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.
