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.

With most vehicles moving on to Tesla’s 2025.14 Spring Update, we’re now taking a look at all the undocumented features that were discovered during Tesla’s 2025.8 update.
While these features tend to be smaller in nature, some of them are just as valuable as the features outlined in Tesla’s release notes in the vehicle.
This update includes changes such as improvements to maps, trip meters, and Rainbow Road. Let’s take a look at all the undocumented features in Tesla’s 2025.8 software update.
New Map Icons
Not a Tesla App
Icons on the map are being redesigned to be rounder and easier to see. They now feature a white border to make them pop out against a colorful background, which is especially better when using satellite views.
This feature started rolling out slowly but should now be available to everyone.
Trips & Odometer
Not a Tesla App
The Trips display has been improved to show more precise information, and a new metric has been added.
More Precision: The trip meters will now show values with a tenths place when they’re under a certain value. That means that the Current Drive and Since Last Charge trip meters will now show a fractional kWh and a mile. This is especially useful for Current Drive.
The Current Drive meter is automatically reset when your vehicle comes out of park so that it can track your current drive, while the Since Last Charge meter automatically resets after a charging session completes.
More Data: In addition to added precision, the Current Drive now features a new data point. kWh is now shown for the current drive, just like the other trip meters. Previously, the Current Drive showed minutes instead of kWh -- it now features both.
These changes affect the Trips widget in the Model 3, Model Y and Cybertruck. While the added precision is also added to all vehicles under Controls > Trips, the new kWh metric for the Current Drive is only displayed in the small widget.
Additional Tool Tips
Not a Tesla App
Tesla has added some additional tips to the screen that show up in certain cases. For example, if you’re playing audio over Bluetooth, Tesla will suggest that you use their built-in music apps instead of streaming through your phone.
Destination Charging
Not a Tesla App
Destination charging icons are now visible on the map when you have Points of Interest enabled. You can enable Points of Interest by tapping on the map and choosing the Points of Interest icon on the right side near the satellite imagery icon.
Some destination chargers may charge a fee, while others may be open to the public or exclusive to paying customers.
Navigation Improvements
Not a Tesla App
If you're using Tesla's navigation system with voice guidance enabled, the spoken directions will now stop immediately when you end the trip. Previously, the spoken directions would continue being played until the phrase was completed.
Improved Rainbow Road
Not a Tesla App
The rainbow road feature has been greatly improved in this update with FSD. Rainbow road, which can be enabled in the Toybox app, now changes the vehicle's path when on Autopilot from a blue path to a rainbow one.
Previously, Tesla had to overlay the blue path on top of the rainbow colors because rainbow road didn’t support all the features of the path, such as showing chevrons when slowing down rapidly.
With this update, the rainbow path now incorporates all the same features as the blue path when FSD is active.
In addition, if you start Rainbow Road by tapping the right stalk four times, audio will play. Unfortunately, the sound couldn’t be stopped until it was completed before, but with this update, you can now stop the audio by reducing the volume with the left scroll wheel.
Additional Transparency Effects
Not a Tesla App
On Intel vehicles, several modules didn't include a transparency effect. This was primarily due to Intel cars not using the blur effect since it could slow down the infotainment unit.
With this update, Tesla has enabled the transparency effect across a set of modules. Notably, this fixes the issue when using full-screen visualizations where the music player had transparency, but the navigation module on the right did not.
Transparency has also been added to other modules that are displayed over the map, such as the list of Superchargers, destinations, search results, and the ETA / End Trip module displayed at the bottom.
Note: Due to the lack of the blur effect on Intel due to performance reasons, these changes could make some text more difficult to read.
No Phone Key Graphic
Not a Tesla App
The graphic that's displayed in the vehicle when it doesn't detect a phone key has been updated. Tapping on the blue text at the bottom displays the old animation showing you where to tap a key card.
Bluetooth Player
Not a Tesla App
The Bluetooth app typically only displays the connected devices and a button to connect a new device. There was a lot of white space, since there wasn’t much other information to display.
With this update, Tesla is making it easier to jump to another source by displaying available music streaming services underneath the connected Bluetooth device.
Tapping a music service will jump to the selected service.

Next Update
Tesla’s next update is the 2025.14 Spring Update, which has now rolled out to more than half of the Tesla fleet. If you’re still waiting for it, rest assured that you should be updated soon. If you’ve already updated, be sure to check out the undocumented features already found in the 2025.14 update.
Tesla has issued a strong denial in response to a Wall Street Journal report (Paywall) which claimed that Tesla’s Board of Directors had initiated a search for a new CEO.
In a statement posted directly on Tesla’s X account, Board Chair Robyn Denholm denied the report unequivocally. As per the statement, Tesla’s board did not reach out to recruiting firms in search of a new CEO.
Earlier today, there was a media report erroneously claiming that the Tesla Board had contacted recruitment firms to initiate a CEO search at the company.
This is absolutely false (and this was communicated to the media before the report was published).
The statement reaffirmed the board’s position on Tesla’s current leadership and that the board is highly confident in Elon’s ability to continue executing Tesla’s plans and future growth.
This confidence behind Elon follows his recent statements made during the Q1 2025 Earnings Call that he would be stepping back from the Department of Government Efficiency (DOGE) in the coming days and significantly reducing time spent there. Instead, he would be returning to focus on Tesla’s operations and the upcoming deployment of Robotaxi.
Shortly after the denial was posted, Elon Musk also commented on the report, specifically tagging the Wall Street Journal and criticizing their handling of the report.
It is an EXTREMELY BAD BREACH OF ETHICS that the @WSJ would publish a DELIBERATELY FALSE ARTICLE and fail to include an unequivocal denial beforehand by the Tesla board of directors! https://t.co/9xdypLGg3c
We’re glad to see Tesla and Elon set the matter straight, but there could have been a better way to spread this message and maybe even prevent the report from WSJ from going out.
We recently published an opinion piece on why Tesla needs its PR team back, and this specific incident is a good example. Relying solely on platforms like X for critical corporate communications - and in this case, late at night (1 AM EST), with limited reach outside the existing follower base seems like an ineffective way of communicating important company information.
We’d love to see Tesla really put some thought into managing its image, as it seems that several recent reports from major financial news organizations have apparently been wrong.
Either way, the board’s stance is clear - there is no active search underway, and Elon has the full backing and support of the board to lead Tesla toward the future.
