Tesla continues rapid innovation with new seat patent
In February of 2019, Tesla filed a patent for a “Vehicle seat with an integrated temperature-control system,” and now it seems the company has just updated the patent.
The new system will heat or cool the seats as needed with the use of coolant, which will ultimately lead to increased comfort and reduced power usage.
The new system will be much more efficient and comfortable than current heated seat technology. Traditionally, car seats get heated by an electric current that flows through resistors and get cooled by a fan under the seat.
The difference between electric resistor-based seat heaters and these new refrigerant-based seats could be compared to Tesla vehicles with electric heaters and those with a heat pump.
A model with a heat pump extracts heat from a refrigerant that is run through the system instead of generating heat using electricity directly. Heat pumps are much more efficient at generating heat when compared to electric heaters. We’d expect a similar efficiency gain from Tesla switching to these new temperature controlled seat heaters.
Most seat heating and cooling systems have 3 heat/cool settings that must be manually adjusted. These types of seat heaters are basically on/off switches and can not control the temperature of the seat well.
Tesla recently added automatic seat heater functionality to Teslas to help address this issue. The new auto setting will automatically turn on seat heaters then gradually lower their temperature as the cabin warms. However, it appears that Tesla is aiming to provide an even better solution with this patent.
Precise Temperature Control
These new seats would be able to precisely control their temperature so that you can set an exact temperature for your seat just like you do for the cabin temperature.
The new seats would be much more efficient than using electric seat heaters and would provide better cooling than running cold air through vented seats.
Better Cooled Seats
Ventilating air through the seat is rarely enough to remove excess heat for the comfort of the passenger.
Instead of blowing cold air into the seat, these new seats would work like an air conditioning system, by removing heat from the seat. This would be much more effective at cooling down the passenger.
Additionally, traditional seat heating systems take up a lot of space and are ineffective because heat typically has to travel through multiple layers of fabric and other materials.
The same way fluid is used to heat/cool batteries, the new system will more effectively transfer heat with the circulation of fluid in between layers of the seats.
The new patent includes multiple layers inside the seat. Under the outermost layer of the seat, there will be a layer of heating/cooling fluid. The fluid will circulate under this layer through the entire seat to ensure that all parts are evenly heated/cooled.
This invention shows how Tesla is innovating and paying great attention to detail in every possible way to make their vehicles more efficient, comfortable and enjoyable for the user.

In the race to deploy autonomous vehicles, there have been two schools of thought. One is led by sensor fusion, which means the more sensors and the more types, the better. The other is Tesla’s school of thought — vision.
So far, even Google’s CEO, Sundar Pichai, has described Tesla as the leader in the autonomy sector.

A new analysis from Bloomberg (paywall) offers a similar perspective, focusing on the numbers and real-world safety metrics. Tesla’s strategy isn’t just viable - it is far outpacing its competitors.
A Tale of Crash Rates
The most striking numbers from Bloomberg’s analysis are safety-related. According to their comparison, FSD reports approximately 0.15 crashes per million miles driven. In contrast, Waymo reported approximately 1.16 crashes per million miles.
That means that a Tesla using FSD is seven times less likely to be involved in a crash than a Waymo vehicle, even with its bevy of sensors. This is in line with Tesla’s latest vehicle safety report, which notes that a Tesla using FSD is 10 times less likely to be involved in an accident than a driver in any other vehicle.

When it comes down to it, sensor fusion, while it can be fantastic, it simply provides too much data to process and analyze. While LiDAR, radar and cameras all have their unique advantages, cameras end up being the most versatile. Our roads and world were created around vision and audio, so a LiDAR-only vehicle can’t navigate our roadways since it would be unable to see signs or any other object that lacks depth. For LiDAR to be useful, it needs to be coupled with vision.
Vision works well because it applies to all situations, and it’s a system that continues to improve thanks to advancements in image processing and AI. While measurements with vision still lag behind LiDAR, they’ve reached a point where they’d “good enough,” and the millimeter-level accuracy of LiDAR isn’t needed.
When radar and vision disagree, which one do you believe? Vision has much more precision, so better to double down on vision than do sensor fusion.
Besides the difficulty of using sensor fusion, Bloomberg also points out that Tesla’s advantage is in the fundamental cost of the hardware. The Model Y costs just 1/7th of the total cost of a Waymo vehicle.
This enormous cost difference is a direct result of how Tesla and Waymo are approaching autonomy. Waymo’s vehicles are high-end, third-party electric cars, like the now-discontinued Jaguar I-Pace, which are then retrofitted with an expensive, custom-built suite of sensors. This sensor suite includes multiple LIDAR units, radars, and cameras.

Tesla, meanwhile, includes all the hardware for autonomy as standard equipment on each of their vehicles, with a relatively inexpensive suite of cameras and its own in-house designed FSD computer. Using affordable hardware means it’s easy to produce and field more vehicles, resulting in more data.
On top of that, building more vehicles at a lower price creates a larger and larger economic difference as time goes on, as Tesla’s Robotaxis become profitable far quicker than Waymo’s.
3 Billion Miles… and Counting
The biggest advantage that Tesla has over any other entrant into the autonomy ring is simply just data. Tesla’s fleet has gathered over 3 billion miles of driving data globally, whereas Waymo’s fleet is just a minuscule 22 million miles.
Putting that into perspective, for every mile driven by a Waymo vehicle, a Tesla has driven over 135. Tesla’s advantage is also the fact that its data is global. It includes vehicles operating in a range of environments, from deserts to the Arctic, from cities to extremely rural areas, and is capable of achieving generalized autonomy.
Waymo’s data is extremely focused on urban and suburban areas and is effectively unusable for generalized vehicle autonomy. A larger, more capable fleet is the key to providing an effective robotaxi service, after all.
Scaling Manufacturing
Finally, Waymo doesn't produce vehicles. Tesla produces Robotaxis from scratch - every vehicle off the line has the ability to run Unsupervised FSD, and eventually join the Robotaxi fleet. Waymo needs to partner with other companies that have a good platform, and they must adapt their technology to that platform.
Waymo’s fleet is expected to be 2,500 vehicles by the end of 2025, while Bloomberg expects Tesla’s functional fleet to hit 35,000 by the same time. That’s not even counting the millions of AI4-powered vehicles that could also join the fleet by late 2026.
Overall, Tesla is a clear winner in the Robotaxi race - and it isn’t just because of one element. They’re winning through data, cost, and scalability, and the gap will only continue to grow.
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.
Front seats learned some manners

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.
