In 2006, Elon Musk released The Tesla Motors Master Plan. The first plan outlined how Tesla would build an expensive electric sports car, use that money to build a more affordable car, then use that money to build an even more affordable car. All while providing zero-emission electric power generation options. Tesla has since accomplished all of the above, producing millions of electric cars while rapidly bringing down production costs.

A decade later, in 2016, while the first plan was coming to fruition, Tesla released the Tesla Master Plan, Part Deux. In short, the plan would be to "Create stunning solar roofs with seamlessly integrated battery storage. Expand the electric vehicle product line to address all major segments. Develop a self-driving capability that is 10X safer than manual via massive fleet learning and enable your car to make money for you when you aren't using it."

While this plan has yet to be fully realized, a third plan may indicate that the second plan is within reach. Tesla has made huge progress with its FSD beta program and Elon Musk recently doubled down that Tesla will release FSD later this year. The production of the CyberTruck and Semi is set to begin next year. As the second plan is coming together, Elon Musk tweeted that he’s working on Tesla's “Master Plan Part 3

Elon further hinted at the subject of the master plan in another recent tweet:

This tweet gives us a lot more insight into what Tesla is planning. It is now clear that a key part of the plan will be to “scale to extreme size to shift humanity away from fossil fuels.”

Tesla has put out a 20 million vehicle target by 2030. It sounds like a third plan will address how to achieve or even exceed this target. Despite Tesla's massive growth, the automaker currently accounts for just roughly 1% of the total vehicle market share. Scaling to “extreme size” is necessary to make a significant shift away from fossil fuels. The limiting factor to further scaling is the manufacturing of batteries. In particular, the real bottleneck is the mining of rare earth minerals (copper, lithium, nickel, cobalt etc.) required for battery production.

This is why Tesla’s Master Plan, Part 3 could be centered around rare earth mineral mining. So how does the Boring Company, AI and SpaceX play into mining? One theory is that the Boring Company could create the necessary tunnels and land environment to extract raw materials. The Tesla bot could be used to safely and ethically mine raw materials. SpaceX could use starships to rapidly and cost-effectively transport raw materials across long distances. If the battery limiting factor is conquered successfully, the company could begin to think about other uses for batteries including HVAC systems, pre-built homes, and more.

It’s also possible that Tesla’s Master Plan, Part 3 will involve Tesla’s transition to an Artificial Intelligence and data company. After all, Elon has repeatedly stated that Tesla will be thought of more as an artificial intelligence company than anything else. The company has been focused on solving real-world AI and more recently we had AI day, introducing the Optimus Humanoid Robot.

In the product roadmap update on the Q4 earnings call, Elon stated that "the most important product development is the Optimus Humanoid Robot” which he thinks "has the potential to be more significant than the vehicle business over time. He explained that “labor is the foundation of the economy."

With no labor shortages, humanoid robots could revolutionize the world economy. They could also play a crucial role in scaling to extreme size and overcoming the limiting factor of battery manufacturing.

Here is a prediction of what the Master plan, Part 3 could include:

  • Develop the best AI training supercomputer to solve real-world problems that goes way beyond just self-driving
  • Remove battery manufacturing as the limiting factor to vehicle production by building millions of Tesla bots to eliminate the need for dangerous, boring, repetitive jobs (mining)
  • Synergize The Boring Company, Tesla and SpaceX to mine and transport raw materials on a massive scale

What do you think Tesla aims to accomplish in its third master plan? Let us know.

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

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.
