Tesla patent hints at possible Model S, X refresh with new HVAC system
Details coming out of a new international patent application filed by Tesla reveals an infotainment-controlled HVAC system that could be intended for an upcoming Model S and Model X refresh.
A similar HVAC control system has already been rolled out by Tesla in its compact electric sedan, the Model 3. The Model 3 uses two intersecting planes of air for vertical control. Lateral fins hidden within the electric car’s dashboard provide horizontal air control while also providing a clean, minimalistic look. Tesla’s filed patent describes features that are similar to Model 3’s air vent system that’s controlled through its 15″ center touchscreen. Patent US2017 / 058015 titled “Infotainment System with Air-Vent Control,” describes a system to manipulate the airflow inside the vehicle through the vehicle’s media control unit.
The air vent assembly includes a first vent portion placed in front of the driver and a second vent portion that is placed in front of the passenger. These vent portions may be elongated as compared to traditionally known designs of air vent assemblies in that they have longer, more linear vents instead of more circular or boxy vents.
Embodiments of the present disclosure enhance the capabilities of this air vent assembly to provide air flow in a leftward, rightward, onward, and a split configuration using a single rotary actuator. In certain embodiments, the user interface may also allow a user to define the degree to which the vents may cause air to flow in the rightward, leftward, or split direction.
Similar to Model 3’s unique HVAC system, the one described in the patent application also allows passengers to customize the airflow within the vehicle according to passenger preferences.
In certain embodiments, the user customizes the airflow, for example, the specific direction of the airflow. This can allow for a more comfortable experience for the occupants of a vehicle. For example, certain occupants may desire for air to be directed towards themselves while other occupants may desire the temperature of the vehicle cabin to be set to a certain value without having air directly impinging on themselves.

With anticipation running high that Model S and Model X is due for a refresh, an update to its HVAC system would not only unify the dashboard design across its fleet of vehicles but could also simplify production. For one, Tesla’s unique air vent system requires less hardware and thus minimizes the need for multiple suppliers. Using a simpler design, Tesla’s thinner HVAC system can efficiently utilize space in the dashboard, and provide a much more expansive interior feel. Such a system, as proven by the Model 3, would also give drivers better road visibility.
While Tesla’s international patent application did not specifically mention a vehicle model, illustrations included in the document resembles the design of the Model S and Model X’s dashboard. Figure 1, for example, features a dashboard that is similar to the all-electric luxury sedan and SUV. Apart from a similar-looking instrument cluster and infotainment system, the illustration also features a dashboard curvature that’s aligned with that of Model S and Model X’s current design. Armrest cupholders located between the front seats at the bottom of Fig. 1 also draws resemblance to ones found in the Model S and Model X.
Adopting an HVAC system that’s akin to the Model 3 for the Model S and Model X would likely be a welcomed change for Tesla enthusiasts. During his testing and teardown of the vehicle earlier this year alone, Detroit veteran Sandy Munro, who issued a harsh critique of the electric car’s build quality, admitted in a later comment that the Model 3’s HVAC system was “brilliant,” citing its simple yet ingenious design.
Aside from major refreshes, Tesla continues to improve the components of its vehicles over time. As revealed by Elon Musk in a recent conversation with Consumer Reports’ Jake Fisher, the Tesla CEO noted that improvements have been rolled out to the Model 3 since its production began, from better interior materials that reduce road noise to a software update that improves the vehicles’ controls. Tesla’s flagship Model S and Model X are no strangers to this, and a revamped HVAC system can only improve the experience for its driver and passengers.
Tesla has started to deploy the 2026 Summer Update to owners across its fleet, and among the biggest changes are improvements to Navigation, a new startup animation for the Model 3 and Model Y, Caraoke scoring, and new capabilities for Grok.
As the update has started making its way to some cars, we can now see a few of the features operating in real-time. We will show you what some of the new features look like in this article, along with some additional details on what changed.
Not all of the new features in the 2026 Summer Update have quite made an appearance, but some of them have, so we’ll show those here:
New Animation Screen for 3/Y
Tesla is rolling out a new startup animation for Tesla Model 3 and Model Y owners. This is present in Launch Edition and Performance Model 3 and Model Y, but other trim levels do not have anything like this.

Owners can adjust the color associated with the startup animation to suit their preferences. It is a surprise that more automakers do not focus on this animation for their vehicles; it can be a great first impression piece and make the car immediately feel more luxurious.
Tesla has included this on more premium trims, but it is nice to see it on the Model 3 and Model Y.
Grok Improvements
Grok can now adjust more things in the car outside of the Navigation system. Now, drivers can adjust anything from climate to driving settings by simply speaking to the AI assistant in the car:

You don’t even have to push a button, either. Instead, you can just say “Hey, Grok,” if you have it enabled. That feature rolled out with the 2026 Spring Update just a few months back.
-
This is a great feature, especially pertinent for the Robotaxi platform, as there will be no buttons inside the Cybercab when it eventually starts giving rides to the public. It also broadens Grok’s capabilities, which were relatively limited in terms of vehicle setting adjustments beforehand.
Tesla briefly offered one Robotaxi part in its Parts Catalog for your personal car, only to remove it just a short time after it was first noticed.
Tesla’s Robotaxi camera washer apparatus was briefly available for purchase on the company’s Online Parts Catalog. The camera washer was first noticed on Model Y Robotaxi vehicles about six months ago in Austin.

First noticed by Not a Tesla App, the Camera Washer entries appeared for the new “Juniper” Model Y under a category called “Halo,” which has also now disappeared. Interestingly, Halo probably is related to Tesla’s internal “Project Halo,” which was a project that aimed to retrofit customer-owned Model Ys into functional Robotaxis.
This hardware addition would likely be required for the vehicle to operate as a Robotaxi, as the Camera Washer seems to be a non-negotiable part of the vision-based system Tesla utilizes for self-driving efforts.
However, this part has since been removed and is no longer visible on the EPC.
-
Now the true question lingers: Why would Tesla add this Camera Washer to the Model Y parts catalog? Is it planning to make it available for owners to utilize on their own cars for personal use, or will it become a prerequisite for Robotaxi operation in customer-owned cars?
While discussing the upgrade options for Hardware 3 vehicles during the Q1 Earnings Call, Tesla CEO Elon Musk had said that the company could establish small, satellite shops that would upgrade cameras and self-driving computers. Perhaps this same strategy could be utilized for vehicles that want to be included in Robotaxi but do not have the correct hardware.
AI4 is currently represented as capable of unsupervised self-driving, and the same was said about HW3 at one point, only for Tesla to admit last quarter that it would, unfortunately, not be possible. Perhaps AI4 vehicles might need this camera washer as a prerequisite, just as HW3 cars will need that camera and computer upgrade.
This could be the first hint of that’s where we are headed.
Tesla has started rolling out a broader change to the ride experience for its Robotaxi fleet by silencing turn signals, but the change is certainly polarizing.
Tesla has generally made it clear that its purpose-built ride-hailing platform, Robotaxi, will cater to the rider in nearly every way possible. This includes having climate preferences, music, and other personal settings loaded up in the car as the rider enters.
But Tesla is taking it a step further by muting turn signal chimes altogether, a change that appears to be a way to make the ride more peaceful:
Tesla has finally turned off the blinker/turn signal noises in their Model Y Robotaxis.
This is a small update, but will definitely be noticeable for riders. It didn’t really make much sense to leave the turn signal sound on when it’s Unsupervised. pic.twitter.com/ITwx60PAMO

However, there are a handful of people who are not thrilled about this change. Turn signals are a conditioned part of the human mind for those who ride in a car regularly.
-
Taking a turn without one feels strange and odd, and not hearing it click while activated could set off some alarms for riders, who might use the noise as confirmation that other drivers know of their intention to turn.
I kind of like it being on, threw me off when riding with Zoox who has had it disabled

Turn signal noises are still audible in customer cars, so if you use FSD in your personal vehicle, you will still hear the turn signal.
The move is certainly one that is unique, but not one that separates it from other ride-sharing services. In a normal car, the clicking sound confirms to the driver that the blinker is active. In a fully driverless Robotaxi, that feedback serves no purpose for passengers, other than peace of mind.
