FSD Beta V11 will be Tesla's next major FSD update
@xXIczNZWJUuJmGv
Stop me if you’ve heard this before, but Elon Musk says Version 11 of Full Self Driving will be released in two weeks. Tesla’s CEO has promised the long-awaited FSD V11 a few times. Most observers were certain it would be part of the Holiday update, but here we are in the second week of 2023 without Version 11.
However, unprompted, Musk responded to a general tweet about Tesla and the stock price. Musk tweeted: Looks like V11.3 will be ready for wide release in about 2 weeks. Many major improvements.
Improved Highway Autopilot
This is the build that has been touted by the CEO as the big one for several months now. The big change in FSD Beta V11 will be the new highway Autopilot experience. Tesla is leveraging and adapting the neural nets they use for city driving to highway driving. Navigate on Autopilot hasn't seen many advances in the last few years, but that's expected to change with this update.
Highway driving is notably easier than city driving, but when Tesla finally merges the two tech stacks we should see several improvements to Navigate on Autopilot, including smoother lane changes, merges and better transitions when entering or exiting the highway.
FSD Beta V11.3 may also finally include Tesla's 'reverse creep' feature which has been talked about for some time. This will allow the vehicle to reverse and readjust or move out of dangerous situations.
Release Notes
The FSD V11 release notes were partially leaked in November. However, there are likely now even more improvements in V11.3. The notes for V11 stated:
Enabled FSD Beta on highway. This unifies the vision and planning stack on and off-highway and replaces the legacy highway stack, which is over four years old. The legacy highway stack still relies on several single-camera and single-frame networks, and was setup to handle simple lane-specific maneuvers. FSD Beta's multi-camera video networks and next-gen planner, that allows for more complex agent interactions with less reliance on lanes, make way for adding more intelligent behaviors, smoother control and better decision making.
Improved Occupancy Network's recall for close by obstacles and precision in severe weather conditions with a 4x increase in transformer spatial resolution, 20% increase in image featurizer capacity, improved side camera calibration, and 260k more video training clips (real-world and simulation).
It's Unknown Who Gets FSD Beta V11
It’s unclear who's getting FSD Beta V11 in two weeks. Will it include a wider range of employees, or will it go to the OG beta testers as well?
With the latest Tesla updates, it appears Tesla has finally merged FSD Beta software and production builds, meaning that FSD Beta is available to everyone in the U.S. and Canada. However, does that mean all FSD Beta users will get v11 right away? Likely not, as Tesla will probably want to roll it out slowly and release minor revisions before everyone has access to it.
What to Expect
Expectations are key. Whenever Elon Musk communicates a date, that is often the best-case scenario and delays are a real possibility.
We may see the first glimpse of FSD Beta V11 in two to three weeks, but it'll likely be in limited numbers.
We know that Tesla employees were testing V11 in November. At that time, it was believed that the program would soon roll out to a small group of public testers to get more input.
We don't know just how far into testing V11 has been. But for Musk, who has been busy with Tesla, Twitter, and SpaceX, to take the time to again give an update and a timeline for V11, the most advanced FSD yet must be coming soon. Right?
Tesla’s been on a roll with Supercharger improvements lately, from the 325kW charging update for the Cybertruck, to 500kW with V4 Superchargers coming next year. While those improvements have been limited to the Cybertruck, Tesla didn’t put all their focus on their new flagship vehicle, but looked at their more affordable vehicles as well.
LFP Battery Heating
Tesla’s Superchargers can now heat LFP Batteries - those that are in the Model 3 and Model Y Rear Wheel Drive variants. This applies to Long Range and Standard Range models, which saw a limited run. This is another update included as part of the 2024 Tesla Holiday Update - which really arrived with a lot of unannounced new features and capabilities.
The change is pretty interesting - Superchargers of the V3 and V4 variety can now pre-heat batteries for Model 3 and Model Y vehicles equipped with LFP battery packs. That means those vehicles are able to get back on the road faster when it's extremely cold. Of course, Tesla still advises you to precondition before you arrive, saving drivers time and money.
Max de Zegher, Tesla’s Director of Charging, also commented on the new feature. Essentially, Tesla is inducing an AC (alternating) ripple current through the battery to warm it up. Keep in mind that Superchargers are DC charging. That means it is possible to get a cold-soaked LFP vehicle on the road 4x faster than before, assuming that it didn’t precondition at all and that it is in the worst-case scenario (below 0ºF).
In essence, Tesla is using some engineering magic to turn the circuits inside the LFP battery into an electric heater - and powering that heater through the Supercharger. An AC ripple current is a small oscillation in the DC charging current that generates heat through electrical resistance, warming up the battery. Those ripples are a byproduct of converting AC to DC and back - so Tesla is using the onboard charger to induce those ripples to warm up the battery. Definitely an innovative technique that’s really only possible with the versatility of the NACS connector.
We’re hoping Tesla can implement this across their full lineup of vehicles, but we’ll have to wait and see how it is trialed across LFP vehicles first and if it is even possible on vehicles with 2170 or 4680 battery packs.
Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.
FSD V13.2.4
A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.
FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.
While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.
It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.
Same Update, Multiple FSD Builds
What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.
The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.
While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.
What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.
While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.
While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.
Thanks to Greentheonly for helping us understand what happened with this release and for the insight into Tesla’s processes.
