Christmas came early for some Tesla owners thanks to the new High-fidelity Park Assist that was part of the Holiday Update. Ashok Elluswamy, Tesla’s Autopilot Software Director, took to X to show off Tesla’s latest technology, a complete overhaul of the parking experience, blending advanced 3D visualization with real-time environmental mapping.

First, the bad news. The new technology is initially available only to customers with Tesla models that do not have ultrasonic sensors. Elluswamy says models with USS will get the new park assist “eventually” - insert your two-week joke here.
Future
Any time more than one sensor is used to create an output it gets more complicated because the output from each sensor won’t match exactly. Ultrasonic sensors are extremely good at what they do and produce extremely accurate output of distances where they’re aimed, but they can also miss things that are lower to the ground or higher up, things that Tesla Vision may be able to see.
It’s not clear whether Tesla will fuse the two sensor outputs into one or whether they’re planning on disabling USS completely when an improved version gets rolled out to vehicles with USS.
Requirements
The requirements for this new feature are still up in the air as well. All the vehicles that have received the new park assist have Tesla’s latest Ryzen-based infotainment CPU (MCU 3), however, we don’t know whether that will be required for these new visualizations.
Enhanced 3D Surroundings Reconstruction
Elluswamy's posts revealed that the new High-fidelity Park Assist is replacing the older 2D obstacle detection system with a sophisticated 3D reconstruction of the Tesla's surroundings. This breakthrough is an extension of Tesla's Occupancy Network, now boasting much higher resolution, thereby aiding drivers in navigating tight parking spots with unprecedented precision. The engineer posted: “In addition to obstacles, we also predict painted lines on the ground, also in 3D. Together, these help perform the full parking maneuver just by looking at this one screen.”
First Release and Upcoming Enhancements
Acknowledging that this is the initial version, Elluswamy teased future updates to the technology. These updates will likely include improved geometric consistency with the cameras and enhanced tracking of occluded obstacles. Even in its emergent stage, this technology significantly improves upon previous parking assistance systems. He stated: “This is the v1 release of this technology, and will have follow up releases that have even better geometric consistency with the cameras, better persistence of occluded obstacles, etc.”
The visualizations provided by this updated Park Assist system are impressively accurate. The 3D models, which change color based on proximity to the vehicle, offer a new level of awareness and interaction for drivers. This system, which uses vision technology to render 3D models in a way typically associated with LiDAR, is a significant step forward in Tesla's software development.

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.
Powershare is a feature that is currently exclusive to the Cybertruck and one of the truck’s best selling points. With its massive 123kWh battery, the Cybertruck can supply power to your home when paired with a Tesla PowerShare setup. This system also includes automatic backup failover, ensuring seamless power during home outages.
Powershare Limitations
One major limitation has been that Tesla Powerwall owners couldn’t use the PowerShare feature due to software conflicts, which took a while to resolve.
However, the challenge wasn’t just software-related—Tesla also had to navigate several regulatory hurdles. A key issue was that homes with solar integrated into their backup solution couldn’t use PowerShare. This meant homeowners had to choose between powering their home with solar or their Cybertruck, rather than combining both sources.
Solar Update
Thanks to a recent update, PowerShare is now available for customers with solar in their backup circuit, allowing them to power their home with solar energy and even charge their Cybertruck during an outage—seamlessly and automatically.
Additionally, PowerShare is now enabled for customers with a backup switch, provided they are in an approved utility region.
Powerwall Update
PowerShare will be available to Powerwall owners using a Wall Connector Gen 3 or Universal Wall Connector starting in Q3 2025. While still a few months away, this is great news for Powerwall users looking to leverage the Cybertruck’s large battery as an extended backup power source for their homes.
Wall Connector Gen 3
Interestingly, Tesla has now enabled PowerShare for the Wall Connector Gen 3, a change that appears to be driven more by regulatory approvals than hardware or software limitations.
Currently, Tesla requires customers in the U.S. and Canada to use the Universal Wall Connector for PowerShare, even if they already own a Gen 3 Wall Connector. However, this policy will likely change in the coming months as the Gen 3 Wall Connector gains official support.
Author’s Note - Powershare Pricing
We’d love to see Tesla reduce the cost of PowerShare installation. The author received a quote for a home setup with two Wall Connectors in a standalone garage with its own breaker panel. Since the home already had an automatic Generac backup failover switch, much of the required electrical work was already in place.
Despite this, the final quote for installation came in just under $12,000 CAD (about $8,500 USD at the time). This covered only the installation of a Tesla Gateway, replacing a single Gen 3 Wall Connector with a Universal Connector, and some additional wiring. Even with the Foundation-Series discount of $3,500 CAD, it won’t be cheap to install.
While this update is a great step forward, Tesla needs to make PowerShare more accessible—both by expanding it to more vehicles and by lowering installation costs. It’s an incredibly useful feature that will help sell vehicles, but affordability remains an issue.
