Tesla FSD v9, how it's going. We take a look at what v9 is capable of

By Henry Farkas

It’s presumptuous of me to write an article on Tesla’s FSD Beta v9 considering the sad fact that my Tesla Model 3 doesn’t have it. I’ve had the urge to do it anyway, but what could I say? Well, I’ve watched videos and read articles written by people who have it, and now I have something to say that no one has said. I’m going to compare Tesla to Mercedes Benz.

There are numerous people who now have access to the FSD v9 Beta, and many of them have now posted videos online to describe their experience. We take a look at some of those most interesting videos below.

All these reviewers mention that v9 is much smoother and more human-like in its driving leading to fewer disengagements. You’ll note that even though v9 is a better driver, it’s not yet a human-level driver. There’s no such thing as disengagement when a human is driving.

AI Addict took his Tesla with v9 down Lombard St. in San Francisco and here's how it did:

For those of you not familiar with San Francisco, Lombard St is extremely curvy and hilly. It’s also very narrow. It’s a one-way street, so you have to drive downhill. The last time I drove down that hill, I scraped my car on a cement curb. AI addict went down the street twice, and he had to take over both times. Clearly, Lombard St is an edge case that the neural network hasn’t mastered yet.

Here’s a v9 video in San Francisco that doesn’t go down Lombard St, but that does still need some human interventions.

Here’s a video by Dirty Tesla in downtown Ann Arbor. He did need to intervene a number of times.

So, basically, v9 is much better than v8, but it’s still not able to drive as well as the average human driver. So, what else is new? Here’s the kicker.

There’s an article in Engadget that describes the author's test track experience in a Mercedes Benz with level 3 self-driving. Benz is planning to release level 3 within a year.

Below you have the six levels of vehicle autonomy as defined by the SAE International group, which defined the standards the US goverment now uses.

SAE Internationa autonomy levels

Here’s the thing about the Mercedes Benz version of level three. It’s geofenced to limited access highways, and it’s velocity fenced to speeds of less than 60 kilometers/hour which translates to speeds of less than 37.2 miles an hour. So if you buy one of these cars for the level 3 self-driving feature, you’ll be able to use it only on limited-access highways during traffic jams. According to the video, you’ll be able to watch movies, play video games, and send texts while in traffic jams, that is unless the police see you doing those things. You’ll be able to keep your hands off the steering wheel, but you still have to be ready to take over instantly if the car decides it doesn’t know what to do. If you fall asleep or raise a newspaper high enough so the interior camera doesn’t know if you’re awake and alert, the level 3 self-driving feature will stop working.

So now, let’s get back to Tesla. Although I don’t have FSD Beta v9, I do have Navigate on Autopilot on my Model 3, and that’s what gets used on limited-access highways even on cars with FSD Beta v9. So here’s my experience on limited-access highways.

I do have to keep my hands on the steering wheel, and I’m not permitted to text, play video games, or watch movies even when I’m in a slow-moving traffic jam. Frankly, I wouldn’t feel safe doing those things while driving any car including a Mercedes. And keeping my hands on the wheel seems like the right thing to do in a car that might want me to take over at any moment. It would take one or two tenths of a second for me to get my hands onto the steering wheel if they were off the wheel when an emergency situation arose. It would take one or two seconds to figure out what to do if my mind was on a text, a video game or a movie when a disengagement happened. Even a tenth of a second could make the difference between a close call and an accidental crash.

For the most part, the only time I ever need to intervene while on a limited-access road is when my Tesla and I disagree on which is the most propitious travel lane. This sort of disagreement happens often enough that I have the settings adjusted so that the car needs my consent before it changes lanes.

But if you’re willing to let your Tesla decide which lane to travel in, then Tesla FSD non-beta is already more powerful than the Mercedes level 3. Yes, you need to keep your hands on the wheel and you’re not permitted to watch movies. But otherwise, the Tesla will drive itself as well as the Mercedes, and it will do that very well at full highway speeds, in stop and go traffic jams and everything in between. Level 3 self-driving below 37 MPH isn't an improvement over advanced autopilot.

Tesla's Autopilot is currently a level two driving feature, which basically means that it should be used as an aid to drivers, but that it does not drive on your own. If you've ever used Autopilot then you'll know that Tesla is right on the cusp of level three. With the FSD Beta, I believe Tesla is planning on pushing level three automation to everyone who has purchased the FSD package. Level three is where the FSD features break free and stop just being an aid and turn into an "autonomous" vehicle that the driver should pay attention to, and not just at 37 MPH.

Tesla LFP Batteries Can Now Be Warmed up While Supercharging Using Innovative Feature

By Karan Singh

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 Included FSD V12.6.1 and V13.2.4 in the Same Update: What Caused This and What It Means

By Karan Singh

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.

While this update focuses on bug fixes, Tesla’s already working on bigger features for FSD V13.3, which we have already confirmed to include improvements to highway following and speed control.

FSD V12.6.1

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.
