Exclusive: Tesla Adds HW3 Support to FSD v12.5.1.4 [Confirmed]

Not a Tesla App

Last night Tesla rolled out update 2024.26.15 which included FSD v12.5.1.4. Although the release notes remain the same with this update, the big news is that Tesla has finally added support for hardware 3 vehicles to this FSD 12.5 version.

Once the release went out, we heard rumblings early on that update 2024.26.15 may add support for hardware 3, however, today we’ve been able to confirm that Tesla has HW3 vehicles running this latest FSD update.

Elon Musk initially said that FSD 12.5 was expected to be available for HW3 in about 10 days after it rolled out to AI4. Although that date has come and passed, it finally arrived for employees last night. Although It’s only been about three weeks, it felt like an eternity for HW3 owners who have been anxiously awaiting this update. Many owners weren’t sure whether their vehicles would be able to run the latest version of FSD once the original goal of 10 days was missed. This is one area where Tesla can stand to improve — consumer communication.

Rollout Plan

Although Tesla has internal HW3 vehicles running update FSD 12.5.1.4, their public rollout plan may not go to HW3 vehicles initially. Tesla may choose to roll out the update to vehicles with HW4 first to confirm there are no regressions before proceeding with the launch on HW3 vehicles.

Keep in mind that not every release that goes to employees ends up going out to the public. However, most releases usually start rolling out to early-access customers within a few days if there are no major issues.

HW3 vehicles are currently running FSD v12.3.6, while most HW4 (AI4) vehicles are running FSD v12.5.1.3. FSD v12.5 in general includes a huge array of optimizations and is supposed to be as big an improvement as the capability jump between v11 and v12.

We don’t expect any new features in FSD v12.5.1.4 besides HW3 support as that would complicate solving any potential regressions. However, we’re still awaiting several new features that come in a later version of FSD v12.5 such as nag-less FSD using sunglasses, FSD support on the Cybertruck, improved lane changes, end-to-end neural networks on the highway, and even Actually Smart Summon.

What’s Included & Who’s Eligible

This update is based on Tesla’s 2024.26 code branch, meaning that everyone who subscribes or owns FSD will be eligible to receive it. Tesla is already testing update 2024.32, but it hasn’t gone out to customers yet.

This FSD update will include everything in update 2024.26, Tesla’s “Summer Update.” This includes YouTube Music, Amazon Music, Parental Controls, a new climate screen and much more.

Hardware 3 Optimization

FSD V12.5 rolled out to AI4 vehicles much earlier than hardware 3 vehicles – as code optimization was required to have the FSD model run on the older hardware. It seems that the extra compute offered by AI4 vehicles has allowed Tesla to release V12.5 faster, which also helps them gather more data.

Now that HW3 support has been released, this could set the new tempo for new updates. Major FSD updates – V12.6 or V12.7 will likely also have AI4 support before hardware 3 support, as it seems easier to develop with more hardware power and then later optimize code once you have a working product. However, Tesla has committed to maintaining hardware 3 support, even if the code requires optimization to function on older hardware.

Divergence

AI4 only really started rolling out in the middle of last year, with most customer vehicles arriving with AI4 near May 2023. The optimization gap has been a surprise, especially since AI4 is still running hardware 3 in emulation mode. There will be a divergence between AI4 and Hardware 3, and Elon has mentioned that the new supercomputer cluster will be dedicated to preparing for AI4, and in the future, AI5.

Will HW3 FSD Be the Same As AI4?

This is going to be a big one for most people – after all, we’re estimating that nearly 85% of Tesla’s current fleet, if not more, is still on hardware 3. Did Tesla manage to fit the complete AI model, with all its parameters – a 6x increase over V12.3.6 – onto Hardware 3?

If there were compromises, we’ll need to watch and see. Hopefully, some enterprising Tesla X or YouTube owners will record a test drive on v12.5.1.4 on both, a HW3 and AI4 vehicle for us to compare the differences. We’re hoping that since the official divergence of hardware hasn’t happened yet, at this point, we won’t see any differences.

Upcoming Features

Once FSD v12.5 rolls out to hardware 3 vehicles, we can look forward to the upcoming list of features, including more natural and better-planned turns, the E2N highway stack, and vision-only monitoring with sunglasses. Of course, there are a few other hotly anticipated features we’re waiting for, but which aren’t on the Upcoming Improvements list provided in the patch notes – including Park Seek and Banish Autopark, as well as vehicle-to-fleet communications and FSD understanding hand gestures.

We’re hoping to see these features come in point releases of FSD V12.5, which means they should arrive at similar times for HW3 and AI4 vehicles.

Tesla Introduces Hands-Free Frunk Opening in Update 2024.32.3

Not a Tesla App

In Tesla’s upcoming update, 2024.32.3, Tesla has added hands-free support for opening the vehicle’s frunk. This follows the Spring Update (2024.14), which added Hands-Free Trunk support for certain vehicles.

When hands-free trunk support was added earlier this year, it was supported on vehicles that include an ultra wideband chip, which includes the refresh Model S, new Model X, and the 2024 Model 3. Due to the hardware requirement, these will be the same vehicles that support the new Hands-Free Frunk feature. Legacy vehicles without UWB will unfortunately not support either feature due to the hardware requirement. UWB enables far more accurate tracking of the phone key, allowing Tesla to pinpoint its exact location relative to the vehicle.

The Cybertruck interestingly also includes an ultra wideband chip, however, it didn’t include the automatic opening of the gate earlier this year. However, we expect the Cybertruck to also receive the hands-free frunk opening in this 2024.32.3 update or relatively soon afterward.

Update: The Cybertruck is receiving hands-free frunk support in the 2024.32 update as well.

Hands-Free Frunk

The Hands-Free Frunk works similarly to the trunk feature – with an iPhone 11+ and a recent version of the app, you’ll be able to stand in front of your vehicle, and the Frunk will unlatch after sounding a chime. On some vehicles, the frunk will immediately open after being unlatched, however, you’ll need to manually close it.

This new feature isn’t enabled by default – you’ll need to go to Settings > Locks > Hands-Free Frunk to enable it.

At this time, Tesla doesn’t support UWB on Android devices, though both the Hands-Free Trunk and Hands-Free Frunk support will come to Android users in a future app update, according to Tesla.

Exclude Home

With the addition of the hands-free frunk opening, Tesla has also added a new option. You can now choose to disable the automatic opening when your vehicle is located at home to prevent you from accidentally opening. This will apply to the automatic frunk and trunk. In addition, in the Model X, you’ll also be able to disable the self-presenting doors at home. This is a great addition as many people have kept the hands-free feature disabled due to it awkwardly opening in the garage.

In the 2024.32.3 update, Tesla also mentions that they’ve improved the detection of the phone key, which should make the feature more reliable and faster when approaching the vehicle from the front or rear.

Tesla’s Referral Program Launches in Europe

Not a Tesla App

Following its recent launch in the United States and Canada, Tesla has launched their referral program in several European countries as well.

The program is available in Germany, Norway, France, the Netherlands, the United Kingdom and possibly others. The program is almost the same as the one available today in North America, with rewards for each referral and a discount for those referred. The cap in Europe is also ten per year.

This program comes right on the heels of a 0% financing offer for the Model Y in Sweden and France. While referrals aren't currently available in Sweden, the 0% financing still is.

European Referrals

The European Referral program accounts for country and local currency, where applicable.

The referral reward program is comparable to the one available in North America. After exchange rates, there is only an approximately 10% difference between the available rewards in the US and EU.

Other Countries

We expect this program to start rolling out to other European countries over the next few days or weeks, as Tesla continues to expand its referral program.
