Tesla’s Six-Seat Model Y Confirmed in Software, May Feature Captain's Chairs, Aisle and Longer Wheelbase

For several months, we’ve been hearing rumors that Tesla is developing a new variant of the Model Y, one equipped with six seats rather than the five or seven we’re accustomed to seeing. Many people have been holding out for exactly such a variant, one that’s big enough to hold larger families without being as tight on legroom as the seven-seat variant.

Now, thanks to confirmation from Tesla hacker @greentheonly, we now have the strongest evidence yet that Tesla is making a six-seat variant, likely in a unique configuration, as he found in the latest batch of vehicle firmware

Green found references to the six-seater Model Y in the 2025.20 update, validating the rumors we’ve heard. Given that the references are showing up in production software, Tesla may now be actively testing the vehicle. The next place to watch will be code in the Tesla app, which should hopefully provide us with some previews of the seat layout. 

Captain’s Chairs

So, what would a six-seat Model Y actually look like? Well, the configuration all but guarantees a 2x2x2 seat layout. That configuration would replace the traditional second-row bench seat with two more spacious captain’s chairs, which will have an aisle between them. That’s a big bump in comfort for second-row passengers, who would have seats more similar to the ones up front. Tesla didn’t include armrests on the six-seat Model X, so it’s likely the Model Y won’t have them either.

For the Model X, the seven-seat configuration is a $3,500 bump in price, while the six-seater costs an additional $6,500, so expect the Model Y to have a similar price structure.

We can also expect Tesla to add some convenience features into this package, similar to the power-reclining seats introduced in the new Model Y, which can automatically fold and unfold with the tap of a button. In a six-seat Model Y, the middle seats would likely be able to automatically move forward and backward, while the rear two seats would be the folding ones.

However, most importantly, this 2x2x2 layout creates a center aisle. This provides easier access to the third row, eliminating the need to fold down the center bench seat to get in and out of the vehicle. That’s a big improvement for families who use the third-row regularly.

Confirming Rumors

This firmware update actually confirms rumors we heard back in December 2024. China’s Latepost and Reuters had already indicated that a six-seat variant was in the works back then, but many agreed that the variant would be an exclusive option for the Chinese market. That particular market prefers having spacious second-row seating, and the six-seater just makes sense there, given the offerings of other manufacturers.

Now, with Green’s assessment that a global release is more likely helps to confirm those reports, while also providing some hope for customers in North America and Europe who have been holding out.

Utility vs Comfort

The plot thickens when we look at the fact that Tesla just teased another recent development - the Model Y seven-seat variant. Some customers in North America and Europe received emails teasing the return of the seven-seat Model Y.

But why would Tesla release both? Likely for similar reasons that they have a six-seat and seven-seat Model X. The answer is that some will value the utility of the seven-seat option, while others will value the comfort and premium feeling of the six-seat option.

By offering both, Tesla gives its customers a bit more customization and preference, especially those who often have to look outside the brand for larger family vehicles.

Longer Wheelbase

While the firmware finding confirms the seating configuration, there have also been some rumors from Chinese bloggers about the possibility of a longer wheelbase, known as version E80. If this proves to be true, the six-seater would be more than just a new interior layout; it would be a fundamentally larger vehicle. Recent rumors suggest the vehicle may have a wheelbase that’s 5.9” longer than the regular Model Y, which would significantly increase the legroom available in the third row. While the third row may have ample legroom in this longer wheelbase, it would likely still be limited for smaller individuals due to the available headroom.

The Tesla Model X is Tesla’s only current offering for larger families, but it costs significantly more than the Model Y. A six or seven-seater Model Y could help open up a whole new category for Tesla.

Price

We expect that Tesla will likely price the seven-seat variant for an additional $2,000 USD ($3,000 CAD), and the six-seat variant for an additional $4,000 USD ($5,000 CAD) in the North American market, based on the pricing of the old seven-seat variant and the Model X’s six-seat premium configuration.

Below is a video of the seven-seater Model Y:

What Next?

The addition of the six-seat Model Y to Tesla’s public software that’s being delivered to vehicles today practically confirms that Tesla is looking to release a six-seat version of the Model Y. While the longer wheelbase remains speculative, we could expect Tesla to unveil a six-seat variant in the coming months. Alongside the seven-seat variant, customers shopping for a larger vehicle will have some additional choices soon.

Tesla to Integrate xAI's Grok Into Optimus, Helping Bring the Robot to Life

Following the recent news of Grok being almost ready for Tesla vehicles, Elon Musk confirmed on X that the next major step is with Optimus, Tesla’s humanoid Robot. xAI’s advanced Grok models will eventually serve as the voice and brain for Optimus. This will be a convergence of Musk’s two biggest AI ventures — Tesla and xAI.

This will combine a physically humanoid robot - the brawn - with the new brains, Grok. This integration is more than just giving Optimus a voice - it suggests that Tesla is thinking ahead and possibly intends to use Grok to understand the environment around Optimus, while FSD will handle the robot’s movements.

A Symbiotic Relationship

The combination of Optimus and Grok creates a relationship where each component plays to its strengths.

For years, Tesla’s robotics team has been focused on the immense challenge of physical autonomy. Optimus learns complex tasks by observing humans, basically training itself through video by watching humans. This helps Optimus develop the physical dexterity needed to work in the real world. This is the brawn - the ability to navigate, manipulate objects, and perform useful work.

Grok provides the conversational brain. It adds a layer of natural language understanding, reasoning, and interaction. Instead of needing a computer, a specialized app, or pre-programming commands to give Optimus instructions, a user will be able to simply talk to it in a natural way. This makes Optimus infinitely more approachable and useful, especially for tasks in a dynamic environment, such as work or at home.

xAI and Tesla

Viewed from a different perspective, this move isn’t just about upgrading one product. It is the clearest evidence that xAI and Tesla are collaborating together to build a single, unified AI platform. Musk’s biographer, Walter Isaacson, believes Tesla and xAI will merge. Seeing Tesla and xAI both play critical roles in creating Optimus makes us believe that it may very well be the case.

Transformation to a Humanoid Robot

The confirmation of Grok in Optimus is one of the most significant milestones for the project to date. While Optimus’s ability to walk and work (and dance) is already an incredible engineering feat, it has all been physical abilities so far. Adding the ability to interact with Optimus in a human-like way will transform Grok from a machine to a true, general-purpose humanoid robot.

The ability to understand nuanced requests, ask clarifying questions, and respond intelligently is what will ultimately make Optimus a daily fixture in our lives.

Tesla’s HW3 Upgrade: What Tesla Has Announced & What to Expect

By Karan Singh

A lot has changed for Tesla owners with vehicles equipped with Hardware 3 (HW3), which was once hailed as the key to unlocking autonomy and Robotaxi functionality.

FSD updates were consistently released, but now, HW3 is stuck on FSD v12.6 due to compute and memory requirements of the latest FSD releases. While HW3 vehicles still run a capable version of FSD, they are considerably less smooth than HW4 vehicles.

This has many HW3 owners curious about Tesla’s plans to upgrade these older vehicles, which were once promised to be capable of true autonomy. Let’s take a look at everything Tesla has said so far about the HW3 upgrade and what we should expect.

The HW3 Predicament

Introduced around April 2019, HW3 was a big leap over HW 2.5 and HW 2 in terms of computing power. For a long time, it powered the FSD Beta program. However, as FSD Supervised becomes more complex and data-intensive, particularly with neural networks moving towards an end-to-end AI approach, HW3 quickly became the limiting factor.

HW3 vehicles are currently running FSD v12.6, which was launched in January 2025, while AI4 is running FSD v13.2.9. However, the latest improvements in FSD v13 are even stretching the capabilities of AI4 hardware.

Tesla’s HW3 Upgrade Promise

To address these concerns, Elon Musk has made increasingly definitive statements. After initially suggesting an upgrade would happen "if needed," he confirmed at the Q4 2025 Earnings Call that Tesla will upgrade HW3 computers for customers who purchased the FSD package.

Musk stated, “That's going to be painful and difficult, but we'll get it done. Now I'm kinda glad that not that many people bought the FSD package, haha.”

While Musk initially stated that Tesla would offer a hardware upgrade if needed, he now made an important distinction, stating that the complimentary upgrade would be available for those who purchased the FSD package. Subscribers and non-subscribers will likely need to pay a fee similar to upgrading from HW2 / HW2.5 to HW3. Interestingly, Tesla was later sued for charging subscribers a fee to upgrade to HW3 and had to waive the cost, so anything can happen with the HW3 upgrade as well.

When Will the HW3 Upgrade Be Available?

Despite Musk’s confirmation of an upgrade, Tesla hasn’t provided any timelines or estimates for HW3 retrofits. The prevailing logic, and one that aligns with Tesla’s approach to engineering challenges, is that the company is unlikely to initiate a mass upgrade program until FSD is much closer to being “solved,” meaning it has achieved true, unsupervised autonomy where a driver is not needed.

Until Tesla knows the final, stable computing power and architectural requirements needed for that level of autonomy, rolling out an interim upgrade wouldn’t make sense. It would risk needing yet another upgrade down the line. Therefore, HW3 owners are in a waiting game - will they wait it for a free upgrade, or will they take one of Tesla’s FSD transfer deals?

What to Expect With the HW3 Upgrade

One thing is clear. The upgrade will not be a simple swap to the current generation of HW4 hardware. AI4, as found in newer Tesla vehicles, has different physical dimensions, power and cooling requirements, and connector configurations that make it incompatible as a direct retrofit into HW3-designed vehicles. It’d require a lot of effort and cost to adapt HW4 for HW3 vehicles.

This means Tesla will have to develop another custom-designed retrofit FSD computer specifically for HW3 replacements. This computer must fit within an existing and defined physical space and operate within the power and cooling budget of older vehicles.

Speculation naturally turns to Tesla’s next-generation FSD hardware, HW5 or AI5. Elon previously indicated that AI5 would appear in new vehicles near the end of 2025, initially citing a timeframe of 12-18 months back in mid-2023. However, it now looks like it’ll ship sometime in the first half of 2026.

Potentially, a variant of this new AI5 computer, perhaps a more power-efficient or underclocked version, could be engineered to form the basis of the HW3 retrofit solution. This is plausible, as newer chip architectures often bring considerably greater efficiency, potentially allowing a more powerful new design to operate within HW3’s constraints.

What About HW4 and HW5?

The current-generation FSD computer, HW4, is already facing some constraints with the latest FSD v13 updates. This means buyers and owners of AI4 vehicles are also starting to have this question creep into the back of their heads… “What about my vehicle?”

Based on Tesla’s official statements on AI5, it is poised to be a powerhouse of an upgrade. That means up to 10 times the processing capability of AI4. This is an immense increase in processing power, and over time, Tesla will likely use every bit of it to make FSD handle as many edge cases as possible. While AI4’s computing power was a modest increase from HW3, the leap from AI4 to AI5 is expected to be significantly larger.

Tesla’s upcoming Cybercab is slated to use the new AI5 computer, but production of the vehicle isn’t planned until 2026.

What About the Cameras?

Tesla’s executive team has stated that the existing cameras on HW3-equipped vehicles are “capable” and that the upgrade will be focused on the FSD computer. While the AI4 cameras offer a much higher resolution than HW3, Tesla says they’re not needed. This appears to contradict what Tesla is doing as of FSD v13.2. In that update, Tesla introduced processing FSD camera feeds at full resolution, suggesting that there is some advantage to the higher-resolution cameras.

Musk also stated that cameras would not be upgraded in HW3 vehicles.

As we’ve previously covered, the newer HW4 cameras offer several advantages over the HW3 camera generation, which include:

Higher Resolution: The AI4 cameras feature 5 megapixels, compared to the 1.2 megapixels on HW3 cameras, which allows the vehicle to see things further away and in sharper detail.

Improved Dynamic Range and Low-Light Performance: The improved dynamic range allows the system to see more clearly in low-light conditions, such as during sunrise or sunset, or at night.

Wider Field of View: The rear camera on AI4 features a significantly larger field of view, providing greater awareness of the vehicle's surroundings.

It's known that AI4 processes camera data at these higher resolutions, which undoubtedly contributes to its increased performance in decision-making, object recognition (especially at a distance or for small details, such as text on signs), and overall FSD smoothness. 

Therefore, while a new, more powerful retrofit computer for HW3 vehicles will bring substantial improvements, it will still be processing input from the older-generation cameras. Another technical challenge that Tesla will need to address is how to maximize FSD performance using the existing HW3 cameras.

Infotainment (MCU) Upgrade?

Most HW3-era vehicles are equipped with the older Intel Atom-based infotainment computer, known as MCU 2. Newer Teslas, as well as newer HW3 vehicles, use the considerably faster AMD Ryzen-based MCU 3. Given that Tesla sometimes packages the FSD computer and infotainment computer together, it wouldn’t be too surprising to see an MCU upgrade as part of an FSD computer retrofit.

While this would be a welcome improvement, providing a snappier user interface and better media capabilities, Tesla has not confirmed any such plans. The FSD computer and the MCU are technically separate systems, but Tesla usually bundles them together to save on costs. While Tesla has offered paid MCU upgrades in the past (e.g., from the older MCU 1 to MCU 2), there is currently no official upgrade path from MCU 2 to MCU 3. 

It’s best to assume that the promised free FSD computer upgrade will not automatically include an infotainment system upgrade as well, but it’s certainly possible, given that Tesla usually bundles these together.

Playing the Waiting Game

For Tesla owners who purchased FSD with their HW3 vehicles, the commitment for a free hardware upgrade is on the record. However, the "when" and "what" remain tied to the challenge of achieving true, unsupervised autonomy. Once Tesla understands the compute power required to solve FSD, we’ll likely hear more about this hardware upgrade. Until then, we’ll have to hold on tight with FSD v12.6.
