Tesla HW3 FSD Update Coming: What's Included & What to Expect

Not a Tesla App

It's been a while since HW3 owners have received a new FSD update, with the latest update coming with FSD version 12.5.4.2. While this version added vision-based attention monitoring with sunglasses, it’s still far behind the latest features available on FSD v13.2.1.

Tesla shared their FSD roadmap twice in the past few months, but HW3 was mostly left out, except for a single bullet point that stated there would be improved V12.5.x AI models for city driving.

We’ve recently seen HW4 vehicles receive much larger AI models, camera improvements that include processing video feeds at full resolution and 36 FPS, and much more. FSD V13 also gained features such as the ability to reverse and start FSD from park, amongst others.

It’s clear that HW3 is not powerful enough to run these latest FSD models, but HW3 owners are right to feel left out and disappointed with Tesla selling vehicles with HW3 up through the middle of 2023. Elon Musk has stated that Tesla will upgrade HW3 cars if needed, but are left in the dark in terms of what the upgrade will be and when it’ll become available.

Since that comment from Musk and Tesla’s updated roadmap in late October, Tesla hasn’t shared any additional news on HW3, until now.

Ashok Elluswamy, VP of AI at Tesla, has confirmed on X that an FSD update for HW3 owners is coming before the end of the year. Putting aside the 2 weeks joke, he did confirm that FSD V12.6 will be on its way for HW3 vehicles by the end of the year - which just happens to be about 2 weeks away.

FSD V12.6

It seems that the V12.6 build will be unique to Hardware 3 - as there haven’t been any builds with that FSD version yet. The closest build that we have to look at is FSD V12.5.6.4, which only went out to HW4 vehicles. We expect FSD V12.6 to include everything in 12.5.6.4 with possibly some additions.

FSD V12.5.6 brought a lot of improvements. We covered all of the features in FSD 12.5.6 previously, if you want a detailed breakdown and photos of all the features. However, here’s a high level overview of everything that version included:

• Better and More Natural Lane Change Decisions

• Updated Speed Profiles, including Hurry Mode

• Auto Speed Changes

• End-to-End Highway Stack

• Audio Data Collection

These changes greatly improved FSD on HW4, so we’ll have to wait and see if they provide similar improvements for HW3 vehicles. The more natural decisions should improve overall smoothness and get rid of the jerky-wheel syndrome and green-light braking that has become synonymous with V12.5.4.2. Alongside better lane selection, this makes the entire experience much smoother and more fitting of Full Self Driving.

The updated speed profiles are applicable on both roads and highways (up to 50 mph with this version), which means you’ll get an updated Chill Mode (with Minimal Lane Changes), Standard Mode, and the new Hurry Mode, which is focused on driving faster and making more frequent lane changes.

Auto Speed has also been removed in favor of Max Speed, which will let you define an overall max while letting FSD still pick its overall speed up to that maximum set speed. You can adjust the hard max by using your scroll wheel to slow down or speed up the vehicle.

However, the biggest feature in this update is the new End-to-End Highway Stack, which finally brings the benefits of FSD V12 on city streets to highway driving.

The final feature that we’re expecting in FSD V12.6 is the ability to collect audio data to begin training for hearing emergency vehicles. This one will be big and it’s what will make FSD feel very human-like. Tesla is starting off with detecting emergency vehicles, but you can expect them to start detecting much more than that soon.

Tesla hints at that in their release notes, saying that audio sharing will be used for features such as emergency vehicle detection. Expect FSD to react to more in the future, such as vehicles honking or someone yelling. Tesla also said that they’ll be looking to have the vehicle honk when needed.

Why FSD 12.6

It’s interesting that Tesla is choosing to name this version FSD 12.6 instead of FSD 12.5.6.x, like they’ve done in the past. This points at some additional improvements being included, but it’s not clear what they could be. Could Tesla bring down some improvements from FSD V13, or add some features such as the ability to reverse?

Tesla may want to stay away from the FSD V13 name if the HW3 version isn’t going to perform as well as FSD V13 on HW4, but at the same time, they could simplify some FSD V13 features and make them available for HW3 owners.

What’s in FSD V13

Let’s take a quick look at all the features in FSD V13 that weren’t in FSD 12.5.6.x. FSD V13 includes significant improvements to the FSD model that just won’t fit into HW3 that are likely responsible the the smoothness seen in FSD V13. This includes a much larger model, full camera resolution, higher frame rates, and more, but FSD V13 also includes these additional features:

• Speed Profiles on both City Streets and Highways (available on all roads and speeds)

• Integrated unpark, reverse, and park capabilities

• Start FSD from Park

• Improved reward predictions for collision avoidance

• Improved camera cleaning

• Redesigned controller for smoother, more accurate tracking

• Dynamic routing around road closures, which displays them along an affected route when they are detected by the fleet

While the larger model of FSD V13 is not expected to be available for HW3 vehicles, some of these other features have the possibility of making the cut in V12.6.

Legacy Vehicles

There’s no news on Model S and Model X legacy vehicles with MCU 1 receiving the same update just yet. Teslas with MCU 1 did receive FSD V12.3.6 on update 2024.26.3.1, but we haven’t seen anything indicating there will be another update coming soon. However, getting FSD 12.6 out for HW3 with MCU 2 could be the precursor to it becoming available for older MCU 1 vehicles.

We’re super excited to hear Tesla talking about HW3 vehicles and that an update is coming in just a couple of weeks. While it’s not FSD V13, it could provide massive improvements until a hardware upgrade becomes available for HW3 owners.

Tesla FSD in Europe: June Update

Not a Tesla App

The road to bringing FSD to Europe has been a long and complex one and filled with regulatory and bureaucratic hurdles. Elon Musk, as well as other members of Tesla’s AI team, have previously voiced their grievances with the regulatory approval process on X.

However, it appears that there is finally some progress in getting things moving with recent changes to upcoming autonomy regulations, but the process still seems slow.

Waiting on the Dutch

Elon commented on X recently, stating that Tesla is waiting for approval from Dutch authorities and then the EU to start rolling out FSD in Europe. Tesla is focusing on acquiring approvals from the Dutch transportation authority, which will provide them with the platform they need to gain broader acceptance in Europe. Outside of the Netherlands, Tesla is also conducting testing in Norway, which provides a couple of avenues for them to obtain national-level approval.

The frustration has been ongoing, with multiple committee meetings bringing up autonomy regulation but always pulling back at the last second before approving anything. The last meeting on Regulation 157, which governs Automated Lane Keeping Systems, concluded with authorities from the UK and Spain requesting additional time to analyze the data before reaching a conclusion.

Tesla, as well as Elon, have motioned several times for owners to reach out to their elected representatives to move the process forward, as it seems that Tesla’s own efforts are being stymied. 

This can seem odd, especially since Tesla has previously demoed FSD working exceptionally smoothly on European roads - and just did it again in Rome when they shared the video below on X.

DCAS Phase 3

While the approval process has been slow, Kees Roelandschap pointed out that there may be a different regulatory step that could allow FSD to gain a foothold in Europe.

According to Kees, the European Commission is now taking a new approach to approving ADAS systems under the new DCAS Phase 3 regulations. The Commission is now seeking data from systems currently operational in the United States that can perform System-Initiated Maneuvers and don’t require hands-on intervention for every request.

This is key because those are two of the core functionalities that make FSD so usable, and it also means that there may not be a need to wait years for proper regulations to be written from scratch. Now, the Commission will be looking at real-world data based on existing, deployed technology, which could speed up the process immensely.

What This Means

This new, data-driven regulatory approach could be the path for Tesla to reach its previous target of September for European FSD. While the cogs of bureaucracy are ever slow, sometimes all it takes is a little data to have them turn a bit faster in this case.

Alongside specific countries granting approval for limited field testing with employees, there is some light at the end of the tunnel for FSD in Europe, and hopes are that a release will occur by the end of 2025. With Europe now looking to North America for how FSD is performing, Tesla’s Robotaxi results could also play a role.

Tesla Launches 'TeslaVision' Contest With Big Prizes — See Last Year’s Winner [VIDEO]

Not a Tesla App

Tesla’s marketing has always been relatively unconventional, relying on word-of-mouth rather than traditional advertising. The passion of the owner’s community is always massive, but it is especially high now with the launch of the Robotaxi network just around the corner.

Tesla is now tapping into that spring of fan creativity and announced the TeslaVision video contest, with some seriously impressive prizes up for grabs.

Announcing the TeslaVision fan video showcase

Tesla owners & supporters have always been able to see our products & mission for what they truly are.

Your word of mouth has made Tesla what it is today.

The OGs will remember that in 2017, we held our first video contest. 8 years… pic.twitter.com/6pPpkqmqOH

The Contest

The core of the contest is simple. Create a video that shows how your Tesla gives you more in life. Tesla is looking for submissions that highlight themes of freedom, safety, fun, and convenience.

Prizes

The prizes definitely make this contest worth entering if you’re good with a camera and have some basic video editing abilities.

For North America, the prizes include a brand new Model Y AWD Long Range, alongside an all-expenses-paid trip to Austin for a tour of Giga Texas. The grand prize winner will also be able to custom order their Model Y, allowing them to select their preferred wheels and color.

The two runners-up won’t get a Model Y, but they’ll also enjoy an all-expenses-paid trip to Giga Texas for a tour of the factory.

The travel and tour include lodging in Austin for 2 nights, as well as economy-class round-trip tickets from anywhere in North America. Tesla will also provide a vehicle for use during the trip.

Hopefully, these winners will also have the opportunity to experience the Robotaxi network while they’re in Austin, as it’s expected to be opened to the public later this month.

Project Loveday

For long-time followers of Tesla, this contest may feel familiar. The contest is a direct throwback to the 2017 Project Loveday contest, which was inspired by a letter to Tesla from a 10-year-old aspiring marketer. That contest was won by MKBHD, with his submission below:
