European document reveals that Tesla is adding hardware 4.0 to the Model S and Model X
Tesla
Tesla's highly anticipated FSD hardware 4, also known as HW4, will be installed in new vehicles any day. The company received European approval to sell its latest FSD hardware in the Model S and Model X vehicles.
The timeline for deployment of the new computer that operates the most technologically advanced vehicle in the world has been a mystery. There was some speculation that Tesla may hold off launching the highly advanced system until Cybertruck's release. However, only a limited number of Cybertrucks are expected this year, with full production starting in 2024.
Several Changes Incoming
Several other changes are being made to Teslas according to the European Certificate, issued by the Dutch vehicle authority RDW, dated January 20, 2023. The maximum speed for the Model S is increasing to 174 MPH (280 km/h) from the factory. But owners can tack on even more speed with the optional Carbon Ceramic Brake Kit, which will boost the car to the previously mentioned 200 MPH (322 km/h). It sounds like the Carbon Ceramic Brake Kit option may soon become available.
Hardware 4.0
Unfortunately, the European certificate doesn't reveal any details on what is included in Tesla's 4th generation Autopilot hardware. The system is expected to use 5-megapixel cameras, which will give Autopilot a substantial advantage in determining objects that are further away. The new hardware will also include a new FSD computer which is expected to be about 4x more powerful than the FSD computer in hardware 3 today. Additionally, HW4 is expected to include an HD radar, which could significantly improve FSD. In the same line item as the new FSD computer, Tesla also mentions a new GNSS antenna that is used for GPS. However, GNSS antennas also provide support for other systems such as GLONASS, Baidu, and Galileo.
Other Changes to the Model S and Model X
Other approved European updates are new Gen3 inverters and changes to the automatic headlights. In addition, the Model X will have a unified braking system and a new stay arm for the interior rear-view mirror. Finally, the cosmetic changes that rolled out in North America last month will also be implemented in Europe with the rear badging.
Retrofits will not be Offered by Tesla
It is yet to be known when the new hardware will debut, but Tesla will not retrofit the existing fleet. During the fourth quarter earnings call, Elon Musk said that the "cost and difficulty of retrofitting hardware 3 with hardware 4 is quite significant. So, it would not be, I think, economically feasible to do so."
This could be due to the new HD radar, new power, or space requirements for the new computer or radar, or due to complexities with wiring harnesses. It would also put a huge burden on Tesla Service, which would have to upgrade millions of vehicles. There could also be more to hardware 4.0 that has not been disclosed.
Model 3 and Model Y
It's not surprising that Tesla has decided to introduce hardware 4.0 to the Model S and Model X first. These are lower-volume vehicles and it makes sense for them to slowly roll out these changes. Parts may still be limited or Tesla may want to reduce the cost of a recall if there are any issues with the new hardware. We know the upcoming Cybertruck will also use hardware 4.0, but that still leaves the Model 3 and Model Y out. However, we speculate that Tesla will try to get the Model 3 and Y updated as soon as possible. Once the word is out that the Model S and Model X vehicles include hardware 4.0, many owners may prefer to wait before ordering or taking delivery of a Model 3 or Model Y.
We will likely find out more about FSD hardware 4.0 very soon as these vehicles start being delivered to customers.

Tesla maintains two primary software branches: the main feature branch and the FSD branch. In general, the FSD branch lags behind on new features pushed to the main branch but provides a more recent FSD version.
However, now Tesla is updating the main branch to a much more recent version of FSD.
Current FSD Build & Shadow Mode
Nowadays, the main branch always includes an older but stable build of FSD. It’s been on FSD V12.3.6 since July 2024. So, if you subscribe to FSD in North America, this is the FSD version you’ll receive until you get added to the FSD track.
Even if you don’t subscribe to or have purchased FSD, your vehicle has v12.3.6 on it. That includes vehicles in regions where FSD isn’t available for general use, such as Europe and China. In those cases, FSD runs in Shadow Mode, providing training data to Tesla if you’ve agreed to their data privacy policies. So Tesla is always analyzing what the vehicle would do compared to what the driver does. When there are contradictions, these are the clips and data Tesla will want to analyze.
FSD V12.5.4.2 on Main Branch
For the first time in five months, Tesla has now updated the baseline version of FSD in the main branch. The new version included with 2024.44 updates is FSD v12.5.4.2. This Tesla is updating the baseline FSD version to FSD V12.5.4.2
FSD 12.5 includes many features for a much smoother experience compared to FSD 12.3.6. Many users will appreciate that it gets rid of the steering wheel nag and instead relies on the cabin camera to provide real-time driver monitoring. This version also includes support for sunglasses with driver monitoring. It’ll be a big upgrade for anyone coming from FSD 12.3.6.
It's always a good thing when Tesla updates the baseline FSD version—that means that Tesla is confident that this new baseline is considerably safer and will continue to train the fleet against it.
What Update Am I Getting?
If you’re already on FSD V12.5.4.2, you’ll likely remain on that FSD build unless V13.3 manages to make its way to the public as Tesla originally planned, but that’s unlikely to happen before the Thanksgiving holiday. In all likelihood, you’ll be getting update 2024.44, which will give you some additional Tesla features while keeping you on the same FSD version.
For those who are already on 2024.44 - if you subscribe now, you’ll have V12.5.4.2 enabled on your vehicle.
If you have a Cybertruck, then you’ll receive update 2024.39.5 with FSD V12.5.5.3. They’re on a unique build for the moment, and this will likely be the case until Tesla acquires enough training data from the Cybertruck fleet.
The Cybertruck is having an eventful November. Just last week, we shared the news that Tesla isn’t offering their in-house wrap service for the Cybertruck anymore; the Foundation Series is now available in inventory in select US locations, Crossbars have arrived, and faster charging is around the corner. Now there’s even more to discuss about the stainless steel beast.
Projection Puddle Lights
Like the recently launched puddle lights for the Model 3 and Model Y, Tesla has introduced a set of add-on Projector Puddle Lights for the Cybertruck. These Cybertruck-specific ones go for $75 USD, or $105 CAD and are available in both the Canadian and US Tesla stores.
However, these don’t have the Tesla wordmark - instead, they feature the iconic Cybertruck symbol and, in our opinion, look even nicer. Here’s to hoping Tesla also introduces a set with the graffiti-style Cybertruck wordmark.
Powershare in Canada
While the Foundation Series Cybertruck has been getting delivered in Canada since November 7th, there was no news on Powershare being supported due to regulatory constraints. On the 20th, Foundation Series owners in Canada began to receive emails to get their Powershare installs started through Tesla’s official installer - Qmerit.
More to follow on pricing and the process as we receive our Canadian quote from Qmerit soon.
FSD in Canada
The Cybertruck Program Manager, Siddhant Awasthi, confirmed that with Powershare now becoming available, FSD for the Cybertruck in Canada will also become available soon. Canadian trucks shipped with a factory software build that didn’t include FSD, but did include TACC and stoplight/traffic control.
Early this morning Tesla began rolling out a new version of FSD 12.5.5.3 for the Cybertruck, which is update 2024.39.5. Will this be the version that rolls out in Canada?
Update: Yesterday, Tesla started rolling out FSD on the Cybertruck in Canada for the first time. The update being rolled out is update 2024.39.5, which not only features the latest FSD available on the Cybertruck, version 12.5.5.3, but it also includes all the features update 2024.38, which includes the huge Sentry Mode improvements that reduce power consumption by about 40%.
Following Integrated Flight Test 6 for SpaceX’s Starship, Elon Musk confirmed that uncrewed Starships are likely to begin making their way to Mars in about 2 years. You’re probably going to ask what’s going to be in those Starships - that’s what Brett Winston on X asked as well. Elon confirmed that Cybertrucks and Optimus robots will be among some of the first items landing on Mars.
That’s a ton of awesome news for Cybertruck, and there’s absolutely going to be more around the corner, especially as we await the big Tesla Holiday Update. While you wait, why not take a look at our Holiday Update Wishlists?
