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.
As part of Tesla’s 2024 Holiday Update, Tesla included two awesome new features - Weather at Destination and the long-awaited Weather Radar Overlay. These two features are big upgrades built upon the weather feature that was added in update 2024.26. The original weather feature added an hourly forecast, as well as the chance of precipitation, UV index, Air Quality Index, and other data.
However, this update also added some smaller weather touches, such as the vehicle alerting you if the weather at the destination will be drastically different from the current weather.
Weather At Destination
When you’re navigating to a destination and viewing the full navigation direction list, the text under the arrival time will show you the expected weather next to your destination. You can also tap this, and the full weather pop-up will show up, showing your destination's full set of weather information.

Not a Tesla App
You can also tap the weather icon at the top of the interface at any time and tap Destination to switch between the weather at your current location and the weather at your destination.
You’re probably considering that the weather at your destination doesn’t matter when you’re three hours away - but that’s all taken into account by the trip planner. It will add in both charge time and travel time and show you the weather at your destination at your expected arrival time.
And if the weather is drastically different or inclement, such as rain or snow, while you’ve got sunshine and rainbows - the weather will be shown above the destination ETA for a few moments before it tucks itself away.

One limitation, though—if you’re planning a long road trip that is more than a day of driving, the weather at destination feature won’t be available until you get closer.
Weather Radar Overlay
As part of the improvements to weather, Tesla has also added a radar overlay for precipitation. You can access the new radar overlay by tapping the map and then tapping the weather icon on the right side of the map. It’ll bring up a 3-hour radar overlay centered on either your vehicle or your route. You can play or pause the animation of the weather overlay, but it’s useful to see the direction the storm is moving in.
You’re able to scroll around in this view and see the weather anywhere, as long as you’re not zoomed out too far. It also works while you’re driving, although it can be a little confusing if you’re trying to pay attention to the navigation system. If you like to have Points of Interest enabled on your map, the weather overlay will hide POIs except for Charging POIs.

Unfortunately, you’ll need Premium Connectivity for any of the weather features to work, and being on WiFi or using a hotspot will not be enough to get the data to show up. The data, including the weather radar, is provided by The Weather Channel.
As for supported models, weather and weather at destination are available on all vehicles except for the 2012-2020 Model S and Model X. The weather radar has more strict requirements and requires the newer AMD Ryzen-powered infotainment center available on the 2021+ Model S and Model X and more recent Model 3 and Model Y vehicles.
While Tesla’s 2024 Holiday Update brought many new features, including Apple Watch Support, Cross Traffic Alerts, Weather Overlays, Search Along Route, and others, there are also several smaller items in this update that didn’t get much attention.
Ambient Lighting Now Affects Easter Eggs
The 2024+ Model 3 and Cybertruck both come equipped with ambient lighting, and Tesla is now taking advantage of this custom lighting feature by incorporating it into several easter eggs.
Rainbow Road: If you head over to Apps > ToyBox > Rainbow Road, you’ll find a new option available that allows the ambient lighting in the vehicle to also change shades while Rainbow Road is active. The Rainbow Road easter egg is a tribute to the iconic course course in Nintendo’s Mario Kart.
Check out the feature in action below:
🇮🇹 Con l’aggiornamento di Natale, quando attiviamo la pista arcobaleno, anche i LED interni diventeranno arcobaleno. Questa è una novità non documentata, scovata da un utente di TESLERS (chiaramente riguarda le Model 3 Highland)
Santa Mode: Just in time for Christmas, Tesla has improved Santa Mode by cycling the ambient lighting between Christmas colors. Similar to Rainbow Road, the use of ambient lighting for the easter egg is optional and can be enabled under Apps > ToyBox > Santa Mode.
When using Santa Mode with ambient lighting turned on, the lights will cycle just between Christmas colors, red, green and white, instead of the full rainbow. There’s a video of the feature below:
The Model S and Model X vehicles that support Steam gaming are receiving a Steam app update in the holiday update as well. This update could end up being very interesting, but for now Tesla says that the SteamOS, which also runs on Valve’s Steam Deck has been updated to version 3.6.
Valve outlines a wide range of fixes and improvements in their release notes for version 3.6, but Tesla simply states that the OS update includes performance enhancements and improved game compatibility.
The SteamOS hasn’t been updated on the Model S and X for quite a while, so we believe there may be more to this besides performance improvements and fixes. We’ll be looking to share some insights into this in the near future.
So, there you have it—three new features in the Holiday update that have mostly gone under the radar. While they may not apply to everyone, there are plenty of other cool features in the Holiday Update, like the arrival of Dynamic Road Closure Routing and Nearby Parking, that are coming to every vehicle, so go check out the full release notes.
