Shortly after the announcement of Rivian and Volkswagen’s joint venture, Rivian hosted a short, impromptu investor call to discuss a few key items. If you want to listen to the call yourself, you’ll need to provide a few short pieces of information at this link. The day after, on the 27th of June, Rivian held its Investor Day.

Let’s dive into all the awesome stuff that was unveiled by Rivian during the call and during Investor Day itself.

Volkswagen Investment

The first item on the list was of course the announcement of the joint venture with Volkswagen. The call confirmed that VW will be providing that $1B initial investment, alongside the $4B planned for 2025 and onwards.

Rivian has said that it intends to use this investment to focus on the Rivian R2 ramp at its Normal, Illinois factory, as well as develop its upcoming facility in Georgia. They also confirmed that they will be providing software and ECU (electronic control units) hardware for Volkswagen EVs going forward, which will be based on the R2 or R3 platforms.

The companies will be sharing the responsibility of the joint venture corporation, and Rivian and Volkswagen will each appoint one co-CEO. If you’re interested in the details of how the Joint Venture and the investment work, we highly recommend you listen to the call.

New Vehicles, New Platforms

Rivian also showed off a slide quite similar to Tesla’s slide at its Shareholder Meeting – with 5 vehicles under the wraps. Of note is the updated R1 Gen 2 platform has a new vehicle, which looks similar to the R1S Suburban Edition that has been previously teased. The R2/R3 platform also has a smaller vehicle in its lineup, which looks similar to a wagon or hot hatch. Finally, the “Affordable Mass Market” platform has a full-size SUV, as well as a smaller SUV and what could be a sedan.

All in all, Rivian has some exciting news to look forward to, with the Joint Venture serving as both a lifeline and an opportunity for Rivian to push towards more affordable mass-market vehicles, which will help cement them as an affordable EV brand.

New Battery Pack and Bi-Directional Charging

Another major update for Rivian’s platforms – including the Gen 2 R1 series and R2/R3 platform, is an updated battery pack. This updated pack is structural – and has greatly reduced the cost of the structural components by approximately 50%, which is a massive improvement. Rivian will be using 4695 cells in their updated pack, similar to Tesla’s 4680 cells. These cell sizes are easier and cheaper to manufacture but cooling them has been difficult – even for Tesla. This difficulty in cooling has resulted in reduced maximum charge rates, but Tesla has recently had some drastic improvements in this field.

Every Rivian vehicle already supports the V2H/V2L vehicle-to-home/vehicle-to-load protocols from CCS, but it has thus far been disabled. Rivian will be introducing a bidirectional charger for V2H, alongside a software update to unlock the functionality on all previous Rivian vehicles.

Electronics and the Maximus Motor

A key portion of Volkswagen’s investment is also access to Rivian’s new electronics – the Zonal controllers. Rivian has built a zone-based ECU that controls various parts of the vehicle in centralized locations – resulting in their Gen 2 platform having 60% fewer ECUs, a 1.6-mile reduction in cable harness length, and a 44lb weight reduction.

These are some pretty impressive numbers and are a great step towards Rivian moving towards scaling mass production of their vehicle platforms.

Of course, it's not just the battery and electronics – Rivian’s in-house motor has received an update, with a 30% cost savings and a 30% reduction in labor per unit for their single-motor-per-axel motor variant. This motor will be going onwards to replace the Enduro and will be the primary drive unit for the R2 and R3 vehicles.

Rivian Spaces, Shop, and the Rivian Adventure Network

Rivian’s sales fronts are known as Rivian Spaces – genuinely a place to get to see a vehicle, hear about it from a Rivian salesperson, and learn about all its features. Spaces have generally been sparsely located – with just 12 open today in 2024, and just 2 open last year.

To address this, Rivian plans a drastic expansion of its Spaces, with 40+ being opened throughout 2024 and 2025. This is going to be Rivian’s big step towards bringing their vehicles to the mass market, and away from the specialty consumers that they target today.

The Rivian Shop will also be receiving plenty of updates – alongside the newly launched shop UI. This will include a dedicated platform for selling pre-owned Rivians, including lease returns.

The Rivian Adventure Network will be opening to the public this summer, which means non-Rivian vehicles will be able to charge there soon for the first time. Rivian has committed to expanding the RAN and aims to fill “charging deserts” that it locates through ABRP.

Rivian previously adopted NACS as a standard and is expected to begin producing vehicles with NACS built-in soon, so we could expect the RAN to also use NACS plugs soon.

Service Centers and Service

Beyond the expansion of Spaces, Rivian currently has 59 service centers open today and aims to have 100+ service centers through 2025. This is a pretty big increase, and Rivian also mentions that it intends to have Rivian Mobile Service be able to reach customers who aren’t near a Service Center.

They intend for their service centers to remain fairly small, with roughly a 50% smaller footprint than other comparables, as approximately 70% of their work orders are completed via mobile service. This is fairly similar to Tesla’s approach with their large-footprint Collision Centers located centrally, and smaller Service Center/Delivery Center combinations spread throughout major cities. Tesla has previously mentioned that approximately 80% of their service orders can be completed by a mobile technician, and Rivian is very similar.

Rivian plans to introduce an AI chat system that can pull vehicle logs and data, as well as known defects to help assist Rivian owners and customers with service requests before they need to speak to an agent. The AI will be able to schedule service appointments, and can even suggest routine maintenance, such as tire rotations. This service will be arriving for Rivian’s commercial vehicle platforms first – the EDV and ECV.

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.
