Tesla’s near-obsessive efforts to improve efficiency shown in new ventilated seat patent
It is no secret that Tesla’s electric vehicles are among the most efficient in the auto industry. This is shown in the gap between Tesla and its competitors when it comes to battery tech and just how far the company’s vehicles can last between charges.
The Model X, for example, is Tesla’s largest vehicle available today, yet it is far more efficient than competitors from veteran automakers such as the Audi e-tron and the Jaguar I-PACE, both of which are smaller and newer than the Silicon Valley-based company’s flagship crossover. Part of this is likely due to Tesla’s proprietary battery chemistry, as well as the design and components of its vehicles themselves.
Tesla optimizes its vehicles’ efficiency in several ways, from equipping its cars with software that optimizes the battery pack to using materials that simply consume less power. The less power is consumed by the car’s systems, after all, the more power there is that could be used to turn the wheels of the vehicle.
An example of this is described in a recently-published patent titled “Vehicle Seat with Integrated Temperature-Control System.” Tesla notes in its patent that heated seats could easily be very inefficient, as they require heat to travel through multiple layers of material.
“Attempts to provide air ventilation through the seat foam are typically insufficient to remove excess heat and provide a comfortable environment for the occupant. Further, conventional heating systems are bulky, occupy space in the seat which typically requires the seat to be thicker, and are inefficient in heating the seat as the heat typically must travel through multiple layers and heats regions of the seat that the occupant does not contact. Hence, there is a need for an improved temperature-control system for vehicle seats,” Tesla noted.
The electric car maker describes how its ventilated seat patent works as follows.
“The temperature-control system is associated with at least one of a seating portion and a backrest portion of the seat. The temperature control system includes a base layer. The temperature-control system includes an intermediate layer disposed adjacent to the base layer. The intermediate layer allows fluid to flow through it. The temperature-control system includes a cover layer disposed adjacent to the intermediate layer. The temperature-control system also includes at least one heating element disposed between the intermediate layer and the cover layer. The temperature-control system further includes a fluid pump to provide the flow of fluid through the intermediate layer,” the company wrote.
Tesla explains that the design outlined in its patent provides a low-cost, low-noise, power-efficient, and effective way of cooling or heating a vehicle’s seats. The company also explained that its patent could be incorporated in any seat, regardless of size and shape.

Being a patent application, it is unknown if Tesla has or will utilize the design it described in the recently published document. Yet, regardless of this, it is difficult to not acknowledge the electric car maker’s constant efforts to improve its vehicles’ efficiency. In a way, the publication of this patent comes at a rather appropriate time for Tesla too, as the company is preparing to unveil its next vehicle, a pickup truck, later this year.
Pickup trucks are by tradition not the most efficient cars on the road, and even the Rivian R1T, a vehicle designed from the ground up to be all-electric, requires a massive 180 kWh battery pack to hit 400 miles of range. That’s a range that the Raven Tesla Model S is already approaching with its 100 kWh battery pack.
At this point in the EV race, it’s evident that the efficiency of Tesla’s electric cars is top-notch, and it will likely take a while before competitors can come close. Rivals will come for the company from several fronts, including veteran automakers and young, upstart manufacturers. But by being a moving target, it will likely be a very challenging task to catch up to Tesla. Very few companies out there could be just as dedicated and near-obsessive with improvement and innovation, after all.
Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…

He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
Tesla has opened its northernmost Supercharger in Fairbanks, Alaska, with eight V4 stalls located in one of the most frigid cities in the U.S.
Located just 196 miles from the Arctic Circle, Fairbanks’s average temperature for the week was around -12 degrees Fahrenheit. However, there are plenty of Tesla owners in Alaska who have been waiting for more charging options out in public.
There are only 36 total Supercharger stalls in Alaska, despite being the largest state in the U.S.
Eight Superchargers were added to Fairbanks, which will eventually be a 48-stall station. Tesla announced its activation today:

The base price per kWh is $0.43 at the Fairbanks Supercharger. Thanks to its V4 capabilities, it can charge at speeds up to 325 kW.
Despite being the northernmost Supercharger in North America, it is not even in the Top 5 northernmost Superchargers globally, because Alaska is south of Norway. The northernmost Supercharger is in Honningsvåg, Norway. All of the Top 5 are in the Scandanavian country.
Tesla’s Supercharger expansion in 2025 has been impressive, and although it experienced some early-quarter slowdowns due to V3-to-V4 hardware transitions, it has been the company’s strongest year for deployments.
🚨🚨 Tesla Supercharging had a HUGE year, and they deserve to be recognized.

Through the three quarters of 2025, the company has added 7,753 stations and 73,817 stalls across the world, a 16 percent increase in stations and an 18 percent increase in stalls compared to last year.
Tesla is on track to add over 12,000 stalls for the full year, achieving an average of one new stall every hour, an impressive statistic.
Recently, the company wrapped up construction at its Supercharger Oasis in Lost Hills, California, a 168-stall Supercharger that Tesla Solar Panels completely power. It is the largest Supercharger in the world.

Tesla shocks with latest Robotaxi testing move
Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”
Tesla Model S vehicles were spotted performing validation testing with LiDAR rigs in California today, a pretty big switch-up compared to what we are used to seeing on the roads.
Tesla utilizes the Model Y crossover for its Robotaxi fleet. It is adequately sized, the most popular vehicle in its lineup, and is suitable for a wide variety of applications. It provides enough luxury for a single rider, but enough room for several passengers, if needed.
However, the testing has seemingly expanded to one of Tesla’s premium flagship offerings, as the Model S was spotted with the validation equipment that is seen entirely with Model Y vehicles. We have written several articles on Robotaxi testing mules being spotted across the United States, but this is a first:

Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”
It seems to hint that Tesla could add a premium, more luxury offering to its Robotaxi platform eventually. Think about it: Uber has Uber Black, Lyft has Lyft Black. These vehicles and services are associated with a more premium cost as they combine luxury models with more catered transportation options.
Tesla could be testing the waters here, and it could be thinking of adding the Model S to its fleet of ride-hailing vehicles.
Reluctant to remove the Model S from its production plans completely despite its low volume contributions to the overall mission of transitioning the world to sustainable energy, the flagship sedan has always meant something. CEO Elon Musk referred to it, along with its sibling Model X, as continuing on production lines due to “sentimental reasons.”
However, its purpose might have been expanded to justify keeping it around, and why not? It is a cozy, premium offering, and it would be great for those who want a little more luxury and are willing to pay a few extra dollars.
Of course, none of this is even close to confirmed. However, it is reasonable to speculate that the Model S could be a potential addition to the Robotaxi fleet. It’s capable of all the same things the Model Y is, but with more luxuriousness, and it could be the perfect addition to the futuristic fleet.
