Tesla's 2024.14.3 update brings some design changes
Klaus Schmid / Not a Tesla App
Klaus Schmid on YouTube has posted a nice video overview of some of the major new features in this major update.
While most of the design changes appear to be limited to vehicles with AMD Ryzen chips, there are plenty of features to be excited about for Intel owners as well.
Parked Visualization
In the video, Klaus of course fiddles with the amazing-looking new vehicle model that is front and center while the vehicle is parked. You can freely pan, zoom, and play with the vehicle. The Cybertruck was the first vehicle to feature this new v12 design and even includes an easter egg when you tap on the glass multiple times. There’s no word on whether there are any easter eggs built into other vehicles.
The 3D model looks fantastic, but it's not immediately clear whether it's the same model that Tesla was using before this update or potentially a higher-resolution version, which could help explain the AMD requirement for this view.
The map while parked is now small and in the top-right corner of the screen. However, you can make the vehicle's visualization smaller so that it goes back to the older look with the visualization on the left and maps on the right.

Spotify Queue
Next, Klaus goes into Spotify, which now gives you the ability to queue up songs instead of just playing a predefined playlist or starting a new song immediately.
Quick Access to Car Wash Mode
Under Controls, you also now have quick access to Car Wash Mode, instead of having to remember it's under Service.
New Wiper Controls
The windshield wipers have been one of the most controversial topics on Teslas, mostly due to their automatic function not always working well. Tesla continues to add wiper controls to make them easier to manage.
In the last few updates, Tesla has now added various ways to control the wipers. You're able to add the wipers button to the dock at the bottom of the screen, use the newer multi-function control to control them with the left scroll wheel, and now Tesla is adding another way to control them.

Easier Way to Change Wiper Speed
With update 2024.14.3, if you press the button on the left stalk to activate the wipers, you can now adjust their speed up by moving the scroll wheel up or down. Before this update, you could do something similar, but it required tilting the scroll wheel left/right, which wasn't as intuitive.
If you have your wipers on and set to a certain speed after installing this update, you’ll now also be able to tap the wipers button to cycle through the various speed options.
While this is a welcomed improvement, all the wiper control changes could be a little confusing for folks who don't follow Tesla as closely as we all do. In the end, the issue comes down to the automatic wiper function not working reliably, which is a little ridiculous since every automaker has already solved this problem with a $4 rain sensor. Tesla makes a lot of gambles, and I guess this one hasn’t panned out.
Full-Screen Visualizations
Owners outside of North America will finally be able to enjoy full-screen visualizations, although unfortunately, it doesn't include the full set of visualizations that are included with FSD. It appears that Tesla is keeping the full visualizations tied to FSD.
For drivers in North America who own or subscribe to FSD, which was recently lowered in price, the new full-screen view brings some improvements.
The new media player is now centered on the screen and includes additional buttons such as repeat, shuffle, search and more. You also get the small map in the corner which is useful to be able to see your next turn.
In addition, Tesla is now leaving the "Navigate to" module on the screen as well, so that you can set a new destination without leaving the admittedly nice full-screen view.
Update 2024.14.3 just started rolling out to owners yesterday, so it will be several weeks before most owners have access to this update. For now, check out all of our coverage and the release notes to see which features you can look forward to.

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.
Having the ability to open your trunk hands-free can be incredibly useful when your hands are full, especially in a busy parking lot.
Tesla vehicles now support opening the vehicle’s trunk or frunk completely hands-free — no foot waving required.
What is Hands-Free Frunk and Trunk?
Tesla implemented its hands-free feature by leveraging your phone’s position in relation to the vehicle. When you stand still behind your vehicle, the trunk will automagically open for you.
While this functionality isn’t available on every vehicle, it’s available on every vehicle Tesla manufactures today, including the new Model Y, the Cybertruck and other recent models.
With a compatible device and a supported vehicle, you can now open your Tesla’s trunk hands-free.
How It Works
Tesla’s hands-free feature requires the use of ultrawide-band (UWB) in the vehicle and on your phone. Apple and Samsung have supported ultra-wideband for a number of years and most flagship Android devices also support the low-energy feature.
Ultra-wideband allows another device to precisely detect its relative location. In this case, the vehicle is tracking where the driver’s phone is in relation to the vehicle. Since the vehicle is able to more precisely track the phone’s location, ultra-wideband also improves Tesla’s phone key feature.
Since the vehicle depends on your phone, you’ll need to have your phone on you in order to activate the hands-free feature. Simply stand within 2.5 to 3 feet from the front or rear of your vehicle for the frunk or trunk to open. You’ll then hear a couple of chimes. If you continue to stand still, then your frunk or trunk will open automatically.
The chimes serve as a warning that the trunk will open if you don’t move, which helps reduce accidental openings.
Hands-Free Trunk in Action
The video below shows how Tesla’s hands-free trunk feature works.
Supported Models
Since Tesla uses ultra-wideband to power the hands-free feature, only vehicles with the needed hardware are supported. The list of supported vehicles includes:
2021 Model S and later
2021 Model X and later
2024 Model 3 (Highland) and later
2026 Model Y (Juniper) and later
All Cybertrucks
Supported Phones
Your phone will also need to support UWB. Luckily, most manufacturers have included UWB in their devices for several years.
Apple: All Apple devices since the iPhone 11 have included UWB, except for the iPhone SE (2nd and 3rd generation). The iPhone 16e also has UWB.
Android: Most Android phones - especially flagship devices - already support and use UWB for other uses, but it’s not available on all phones. If you have a Google Pixel 6 or higher, Samsung Fold 2 or higher, Samsung S21+, or other recent Android phone, then your phone already supports ultra wideband.
Which Models Support Hands-Free Frunk
Unfortunately, not every supported model supports the hands-free frunk and trunk feature. The hands-free frunk feature is only supported on the Model S, Model X, and the Cybertruck. In addition, the Cyebrtruck is the only vehicle with a powered frunk, so while the Model S and Model X will unlock the frunk for you, you’ll still need to lift it and close it manually. The Cybertruck will open the frunk for you, much like the trunk on another Tesla.
Which Models Support Hands-Free Trunk
While most supported Tesla vehicles can use the hands-free trunk, it excludes the Cybertruck, which doesn’t have a powered trunk.
Enable Hands-Free Trunk / Frunk
If you plan to use your vehicle’s hands-free trunk feature, you’ll need to enable it in settings, as it’s off by default. Simply open Controls by tapping the vehicle icon in the bottom left corner, then navigate to the Locks section.
Within the Hands-Free section, you’ll find a few options, depending on your model. You’ll be able to choose whether to enable the hands-free frunk or trunk and whether you’d like to disable the feature at home.
Preventing Accidental Opening - Exclude Home
Although the hands-free feature requires you to stay still in front or behind your vehicle for a couple of seconds, it can still be triggered accidentally if you’re working around your garage. To prevent accidental opening of the frunk or trunk, Tesla allows you to disable the feature while your vehicle is parked at home.
Tesla determines your home location by the address that’s set in your vehicle. However, it also adds a buffer, meaning that your hands-free trunk feature will also not work in your driveway or at your neighbor’s home. The exclude home feature is located in the same spot as other hands-free trunk features, Controls > Locks > Hands-Free > Exclude Home.
If you have a recent Tesla that’s supported, go ahead and give the feature a try.
