A late-night Elon Musk post on X has this writer wondering if the Matrix has a glitch. For over a year, credible Tesla-focused websites and the mainstream media have referred to the Tesla Model 3 as the "Highland." But the company’s CEO says the Highland name “is not real,” although it has been seen in various Tesla documents. The cryptic message comes just 24 hours after the new Model 3 launched in North America. Is Musk simply joking, or is there a deeper meaning to his words?
Reuters was the first to use the word Highland. On November 28, 2022, the news outlet ran an “exclusive” story citing “four people with knowledge of the effort” of a revamped version of Model 3 codenamed "Highland." The name made sense. Although the exact origin remains unknown, there were intriguing theories:
Historical Reference to Ford: Some believe "Highland" might refer to Ford Motor Co's Highland Park plant, the birthplace of Ford's revolutionary assembly line.
Cinematic Nod: Others speculate that the name could be a homage to the 1986 film "Highlander", known for its immortals' battle and the iconic line, "there can only be one." This theory aligns with Musk's penchant for movie references and quirky humor.
A few weeks after the report, the mysterious partially covered Model 3s appeared around California. The name Highland took off from there.
Musk vs. Mainstream Media: A Turbulent Narrative
Elon Musk's relationship with the mainstream media has been tumultuous, marked by a series of confrontations and criticisms. His stance has been particularly conspicuous since he acquired Twitter. This ongoing battle with the press can be seen as a backdrop to the "Highland" mystery, casting Musk's latest tweet in a different light.
Perhaps his dismissive comment about the "Highland" codename might not be a straightforward denial but a nuanced swipe at media credibility. Considering that Reuters, a major news outlet, was the first to report on Highland, it could be interpreted as a continuation of his broader skepticism towards media reporting, mainly when it involves narratives about Tesla.
This dynamic adds an intriguing layer to the story, where the "truth" of the Model 3 "Highland" becomes not just a matter of fact but also a symbol in the larger narrative of Musk's complex relationship with the media. As Musk continues to engage in this media tug-of-war, each tweet and statement becomes a potential chess move in an ongoing battle of narratives.
Tesla Community Reaction
Seriousness aside, the internet did not fail to bring a few laughs in the replies to Musk’s post. Some played with the idea of it being part of a grand simulation, adding a touch of sci-fi flair to the debate. Others jokingly asked if this was all just a clever trick or even a plot twist worthy of a movie. The popular “TMFINR” meme showed up a few times.
A few users leaned into humor and parody, echoing the playful skepticism that often accompanies Musk's cryptic messages. Amidst the laughter, there were genuine queries and theories, with several pondering if "Highland" was just an internal project name or something more.
Rumors and conspiracy theories weren't far behind, as some speculated about hidden meanings and possible secret projects. This led to various interpretations, from outright dismissal to earnest theorizing. Could it also have been used to identify who was leaking information? There are a lot of leaks! YoursYour's truly was reminded of a classic Creed line from The Office:
Overall, the community's response was a lively mix of jest, confusion, and curiosity, showcasing the engaging and speculative environment that Musk's tweets often create. It's a unique relationship between Musk, his projects, and his audience, where a single tweet can ignite a spectrum of imaginative and playful discussions.
The Model 3 "Highland" story continues to blend mystery and speculation, fueled by Musk's latest remarks. The “Highland” name was used internally, as it has shown up in several internal documents, so Musk's post causes some confusion. Does he possibly mean that Highland isn’t a part of the (final) product’s name and shouldn’t be used by media to differentiate it from the previous generation?
Whether a clever ruse, a misunderstood codename, or a media misinterpretation, it is a fascinating example of Tesla's cultural impact. Dare we ask if Juniper is real?

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.
