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.
While Tesla’s 2024 Holiday Update brought many new features, including Apple Watch Support, Cross Traffic Alerts, Weather Overlays, Search Along Route, and others, there are also several smaller items in this update that didn’t get much attention.
Ambient Lighting Now Affects Rainbow Road & Santa Mode
The 2024+ Model 3 and Cybertruck both come equipped with ambient lighting, and Tesla is now taking advantage of this custom lighting feature by incorporating it into several easter eggs.
Rainbow Road: If you head over to Apps > ToyBox > Rainbow Road, you’ll find a new option available that allows the ambient lighting in the vehicle to also change shades while Rainbow Road is active. The Rainbow Road easter egg is a tribute to the iconic course course in Nintendo’s Mario Kart.
Check out the feature in action below:
🇮🇹 Con l’aggiornamento di Natale, quando attiviamo la pista arcobaleno, anche i LED interni diventeranno arcobaleno. Questa è una novità non documentata, scovata da un utente di TESLERS (chiaramente riguarda le Model 3 Highland)
Santa Mode: Just in time for Christmas, Tesla has improved Santa Mode by cycling the ambient lighting between Christmas colors. Similar to Rainbow Road, the use of ambient lighting for the easter egg is optional and can be enabled under Apps > ToyBox > Santa Mode.
When using Santa Mode with ambient lighting turned on, the lights will cycle just between Christmas colors, red, green and white, instead of the full rainbow. There’s a video of the feature below:
The Model S and Model X vehicles that support Steam gaming are receiving a Steam app update in the holiday update as well. This update could end up being very interesting, but for now Tesla says that the SteamOS, which also runs on Valve’s Steam Deck has been updated to version 3.6.
Valve outlines a wide range of fixes and improvements in their release notes for version 3.6, but Tesla simply states that the OS update includes performance enhancements and improved game compatibility.
The SteamOS hasn’t been updated on the Model S and X for quite a while, so we believe there may be more to this besides performance improvements and fixes. We’ll be looking to share some insights into this in the near future.
So, there you have it—three new features in the Holiday update that have mostly gone under the radar. While they may not apply to everyone, there are plenty of other cool features in the Holiday Update, like the arrival of Dynamic Road Closure Routing and Nearby Parking, that are coming to every vehicle, so go check out the full release notes.
At the 2023 Q3 Earnings Call, Tesla provided an update on its next-generation model, what many are referring to as the “Model 2” or “Model Q.” Although the actual model name is yet to be determined, it is known internally as Redwood.
During the 2024 Shareholder Meeting, Musk again mentioned the upcoming model, saying that Tesla is working on new products, including a more affordable vehicle and a larger SUV.
While we know the next-gen vehicle is aimed at the $25k to $30k USD market, we now have some new information thanks to a new report out of China.
Launch & Price
According to the Chinese outlet CNMO Technology News (Sina Finance), Travis Axelrod, Tesla’s Head of Investor Relations, announced plans to launch a new model. Axelrod shared this update while addressing senior corporate investors at an investor conference hosted by Deutsche Bank on December 5, 2024.
The goal of Project Redwood, internally dubbed “Model Q” by Deutsche Bank, is to achieve a post-subsidy price of under $30,000 USD. With the Federal EV Rebate potentially expiring next year, this suggests that the Model Q’s starting price will be around $30,000 USD. For comparison, the Model 3 currently starts at $42,490 in the U.S.
We previously reported that Tesla has already been speaking to suppliers and is looking to begin volume production of the vehicle sometime around June 2025. Of course, prototyping is still necessary, but we haven’t seen any signs of Tesla testing a new vehicle since spotting the Cybercab on the streets ahead of We, Robot.
Specs
The Model Q will supposedly be about 15% smaller and 30% lighter than the Model 3, with an approximate length of 3,988mm, or 157 inches. For scale, the Mini is 157 inches, while the Model 3 is 185 inches, so it’s fairly compact.
The battery will also be smaller to match the vehicle’s smaller size as Tesla tries to reduce the vehicle’s price while maintaining a similar range as its other vehicles. Tesla is expected to offer two models—a single-motor RWD model and a Long-Range Dual-Motor AWD variant.

Motors
Battery Size
Estimated Range
RWD
1
53 kWh
230 miles (375km)
AWD
2
75 kWh
310 miles (500km)
There’s no news yet on the price of the AWD version, but we expect it to be about $5,000 more expensive than the RWD variant.
Once the vehicle ramps up in production, Tesla intends to produce about 10,000 of these per week globally or about 500,000 per year. As Tesla mentioned during one of their previous earnings calls, this next-gen vehicle will be built using Tesla’s current assembly lines with minimal changes. This should allow for a smoother and more predictable production ramp. While Tesla still plans to use its new unboxed assembly process, it’s now saving it for the robotaxi.
We’re expecting Juniper to launch early next year, as production has supposedly already begun at Giga Shanghai, at least on a limited prototyping basis. If the rollout matches the Model 3 Highland refresh, we’ll see Juniper arrive in China first and then make its way to North America and Europe by the end of 2025. The performance variants should launch in early 2026, after the standard models.
If you’re excited about Juniper, so are we! Check out our wishlist of features for Tesla’s Model Y refresh, and see everything we know so far.
