S-Klub LA, a private Coach design studio in southern California, builds and designs artistic automobiles. They’re individually unique and one-of-a-kind, and S-Klub decided that it was time to take their retro touch and put it on a Tesla Model 3.
Tesla rebuilds – using the motors and batteries – are extremely popular with retro car modders. It’s an easy way to have a highly performant vehicle – without needing to hunt down or hand-produce old parts for vehicles that aren’t made anymore. Additionally – this leaves them with a lot more space on the inside and less maintenance to perform. Some modders even go as far as including a speaker to emulate engine noises.
But this rebuild is a bit more unique… Let’s get into it.
Mercedes 300SL or Model 3?
The base body is actually a Mercedes 300SL, with some modifications made to fit the battery, motors, and computers of a Model 3. Interestingly, this isn’t actually a real Mercedes 300SL body, but rather a fiberglass replica. The car was previously displayed at Specialty Equipment Market Association (of the automotive aftermarket) – or SEMA SHOW 2023 in Las Vegas.
The Tiffany 300 SL, as it’s named by S-Klub LA, took some extensive work to build, with many of the parts hand-made and hand-designed to build a convincing classic Gullwing body.
The Tiffany moniker comes from the fashion brand Tiffany Co – it’s their brand Tiffany Green and Blue that decorates this car inside out. The car drives and is fully functional, which is definitely a testament to the team’s engineering skills.
The interior, in Tiffany colours, replete with Tesla steering wheel and central screen.

Mercedes With FSD?
The folks at S-Klub LA did go through the work of re-installing the Autopilot Cameras and re-using the main Tesla infotainment and Autopilot computers – something that very few retro EV-modders do. This vehicle is definitely more Model 3 than Mercedes – the steering wheel and steering rack, as well as the entire central infotainment system are still intact.
According to the listing information – because yes, you could buy this thing if you wanted – since all the cameras and sensors are intact, it is possible to enable Autopilot on this vehicle. We’re not sure exactly how well that would work – considering the positions of the cameras are likely no longer the same as the original Model 3, the wheelbase has been changed, and the car is an entirely different shape.
We definitely would not recommend trying this vehicle with Autopilot - especially given how long it takes Tesla to simply get AP working on a new vehicle chassis like the Cybertruck - which won’t get FSD or AP until V12.5.

Definitely Retro
It’s absolutely an original vehicle – that we can say for sure. The Gullwing 300SL is quite a popular vehicle – a 1955 300SL recently sold in 2022 for $6.8 million at RM Sotheby’s auction – but that was an intact, original vehicle, not a replica hull built over a Model 3.
S-Klub LA doesn’t actually list any prices for their one-of-a-kind vehicles, but if for some reason you love Tifanny colors and the idea of a 1955 Gullwing with semi-functional Tesla Autopilot, you can check out their store page.
Build Process
You can check out a video recap of their build process here.
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.
