Chief Designer Franz von Holzhausen talks about Tesla's upcoming Cybertruck
Tesla
Tesla's Cybertruck is ready to go into production, said the company's Chief Designer Franz von Holzhausen during an interview on the Ride the Lightning podcast. However, the designer admits it's always a work in progress on all of Tesla's vehicles as the team continuously looks for ways to refine and improve the process.
The 55-minute interview covered several topics, but much of the conversation focused on the highly anticipated, Cybertruck. Listeners were teased with what could be in the final product and reminded of how we go to this point.
More Unknown Extras
Despite all the eyes on Tesla at all times, von Holzhausen says some brand-new features are coming with Cybertruck. "I'm not going to talk about them, but I think they'll be pleasant surprises, and I think they are the right things for the product, and they're the right kind of competitive things for the product as well.
When asked about including vehicle-to-grid charging, the function that allows energy to go back to the grid from the battery, or vehicle to home, von Holzhausen said, "I won't comment." Cybertruck being able to act as a boat was not discussed.
Different Logo on Cybertruck
There are no logos on the Cybertruck except inside the charge port. Tesla owners are familiar with the "T" logo that lights up when charging. The prototype Cybertruck has an 8-bit logo in that spot, "in those development days when we were designing the truck, it was such a like a low-resolution, low-bit idea in its kind of simplicity as a form we thought this 8-bit concept. So we did an 8-bit version of the T."
While von Holzhausen says we will have to wait to see if it appears on the production vehicle, he did agree that the 8-bit logo design should be added to shirts in the Tesla store.
More Details on the Unique Exterior
There are so many rare aspects of the Cybertruck, from the design to the stainless steel exterior shell, "We spent a lot of time developing a finish… the stainless is incredibly hard." But how will it hold up against scratches? "In the event that there is a scratch, we do have a process that you could basically buff it or remove the scratch and return to the basic finish."
It appears there won't be any color options available for Cybertruck. It will be stainless steel, "we experimented with some finishes. There is always the opportunity to wrap. The thing we wanted to do is preserve the hardness, and anytime you put something softer like a clear coat or a painted finish on the material, it just then... basically takes away from the idea of putting the hardest thing on the outer surface," said von Holzhausen.
Steering Wheel and Door Handles
Tesla recently made some changes when ordering a Model S or Model X. Buyers can now choose a conventional steering wheel or the yoke. But von Holzhausen is confident about what the Cybertruck will use, "the yoke makes a lot of sense. You know once you experience it, it's a great driving experience combined with Autopilot. It makes the whole kind of user experience in the interior cockpit simpler and cleaner." Last year there were rumors that Tesla may implement steer-by-wire in some of their vehicles, so it'll be interesting to see if the Cybertruck comes with this new feature.
The door handles will also be the same as what is on the Model X with the "chauffer" auto-present doors. However, when asked if that would be the same for both front and back doors, von Holzhausen said, "possibly on the back, there are also buttons."
Cybertruck was Almost Normal
It's been in the works for over half a decade, but von Holzhausen acknowledges that Tesla was considering something more mainstream, even working off silhouettes of what's on the road. "we have an opportunity to do something different, an opportunity that nobody else would have the balls to do, and Elon's like yeah, we've got to do it," said Von Holzhausen.
The designer confessed he wasn't sure about Cybertruck, "I didn't 100 percent know what to expect… It's so different it needs a moment to grow on you. It's like the first time you hear a song. Sometimes it can be grading, or like you're not sure if you like it, you listen to it three or four or five times, and suddenly it's your favorite song. You just need to... because it's so new and fresh you need to get comfortable with it, and I think this like it just is so radically different than expectations."
Finally, von Holzhausen says it's great that other manufacturers have produced electric trucks. He believes Tesla has "moved the needle" and will continue to do so.
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.
