Tesla is designing an electric pump system that makes its drive units even better
Amidst Tesla’s continued efforts to usher in an era of mobility optimized for the convenience and safety of car owners, the electric car maker is exploring new ways to improve its vehicles’ systems. Recently published patent applications, for one, indicate that Tesla is working on better damage monitoring features, as well as safer seats that are capable of classifying a car’s occupants. Apart from these, Tesla is also looking into improving its vehicles’ electric pump system, which could ultimately result in better cooling and diagnostics.
The patent application, published on January 3, 2019 and titled “Electric Pump System and Method,” explores improvements that could be implemented on traditional pump systems used in automobiles. As noted by Tesla, traditional oil pumps, particularly those that are used for EV components such as the drive unit, do not have the capability to monitor oil condition. As a result, oil that is used to lubricate an electric car’s drive unit need to be changed on a regular basis (albeit very infrequently).
In the discussion section of its patent application, Tesla pointed out that traditional oil pumps are unable to accurately determine temperature, since temperature sensors are usually located outside of a conventional pump system. Apart from this, the electric car maker notes that conventional oil pumps are also large and unwieldy due to attachment mechanisms comprised of different parts. With these points for improvement in mind, Tesla has pointed out that there is a need for an “improved oil pump — in particular an electric pump system — designed to work in conjunction with an electric motor.”

Tesla’s patent describes an electric pump system that “presents methods and structures that help overcome the difficulties of operating a cooling and lubrication system, in particular, managing the transfer of heat and assessment of fluid temperature in electric pump systems.” The Silicon Valley-based carmaker describes its electric pump system design as follows.
-->“There is provided an apparatus that includes an electronic control unit, a mechanical pump, and a motor having a first side and a second side, the motor including: a stator, a rotor including a hollow shaft, and a housing around the stator and rotor, wherein the electronic control unit is connected to the first side of the motor, wherein the mechanical pump is connected to the second side of the motor, wherein the hollow shaft defines a shaft inlet and a shaft outlet, wherein the mechanical pump defines a first fluid passageway from a first pump inlet to the shaft inlet, wherein the housing defines an internal motor cavity, wherein the shaft outlet is in fluid communication with the internal motor cavity, wherein the mechanical pump defines a second fluid passageway from a second pump inlet to a pump outlet, and wherein the motor housing and mechanical pump define a third fluid passageway from the internal motor cavity to the pump outlet via a third pump inlet.”
“In some embodiments the apparatus according to the above-described aspect of the present disclosure or any other aspects thereof, a number of optional operations and features may be employed. One optional feature is the electronic control unit further including a thermistor to measure a temperature of a fluid exiting the shaft outlet. Another optional feature is wherein the housing defines a bypass inlet in fluid communication with the internal motor cavity. Another optional feature is at least a portion of the second fluid passageway and the third fluid passageway is common. Another optional feature is the mechanical pump is a gerotor. Another optional feature is the electronic control unit includes a microcontroller controlling the mechanical pump. Another optional feature is the electronic control unit includes cooling ribs.”

With such a design, the fluid temperature inside the electric pump system could be used to control and optimize the lubrication system of a vehicle, thereby improving the efficiency of an electric drive unit. Depending on the temperature of the oil in the system, the electric pump could react accordingly, even warning the vehicle’s computers that something is wrong. The readings from the electric pump system can be used to monitor the health of a vehicle’s drive unit as well. Tesla explains this process in the following discussion.
“The fluid temperature may be controlled to achieve certain lubrication properties. For example, hotter oil has lower viscosity which reduces drag and hydraulic power to pump the fluid, which can increase efficiency. If the oil becomes too hot, however, it will not provide sufficient cooling. The fluid temperature reading feature of the oil pump can monitor the general health and performance of the fluid in the electric drive unit system. For example, if the oil is too hot, the oil pump may alert the car computer that something is wrong, for oil that is too hot can damage or/and reduce the life of some components on the drive unit.”
-->“Stated another way, the temperature of fluid may be used to monitor the health and performance of the drive unit. The ECU may capture other information besides the temperature, such as pump speed, pump current composition, oil pressure, or other information. The information captured by the ECU may then be fed into a proprietary algorithm that monitors oil pump and overall drive unit health. The algorithm may provide an indication of service, such as when oil must be replaced or when the drive train needs to be serviced.”
What is particularly notable is that these improvements could result in enhancements to Tesla’s drive units, which are already among the best in the industry. The Model 3’s drive unit, for one, has been lauded by veteran teardown experts such as Sandy Munro as industry-leading. In a recent appearance at Autoline TV, for one, Munro noted that Tesla’s drive units are practically a class above its competitors.
Tesla’s constant efforts to improve its vehicles are highlighted by the patent applications from the company that have been published over the past months. Among these include an automatic tire inflation system that hints at off-road capabilities for the company’s vehicles, a system that allows Tesla to address panel gaps during vehicle assembly, a way to produce colored solar roof tiles, and even a model that utilizes electric cars as a way to improve vehicle positioning, to name a few.

Tesla Full Self-Driving has warranted a huge switch-up on an essential company strategy as the automaker is hoping to increase the take rate of the ADAS suite.
Unlike other automotive companies, Tesla has long been an outlier, as it has famously ditched a traditional advertising strategy in favor of organic buzz, natural word-of-mouth through its production innovation, and utilizing CEO Elon Musk’s huge social media presence to push its products.
Tesla has taken the money that it would normally spend on advertising and utilized it for R&D purposes. For a long time, it yielded great results, and ironically, Tesla saw benefits from other EV makers running ads.
Tesla counters jab at lack of advertising with perfect response
However, in recent years, Tesla has decided to adjust this strategy, showing a need to expand beyond its core enthusiast base, which is large, but does not span over millions and millions as it would need to fend off global EV competitors, which have become more well-rounded and a better threat to the company.
-->In 2024 and 2025, Tesla started utilizing ads to spread knowledge about its products. This is continuing, as Full Self-Driving ads are now being spotted on social media platforms, most notably, X, which is owned by Musk:

Interestingly, Tesla’s strategy on FSD advertising is present in Musk’s new compensation package, as the eleventh tranche describes a goal of achieving 10 million active paid FSD subscriptions.
Full Self-Driving is truly Tesla’s primary focus moving forward, although it could be argued that it also has a special type of dedication toward its Optimus robot project. However, FSD will ultimately become the basis for the Robotaxi, which will enable autonomous ride-sharing across the globe as it is permitted in more locations.
-->Tesla has been adjusting its advertising strategy over the past couple of years, and it seems it is focused on more ways to spread awareness about its products. It will be interesting to see if the company will expand its spending even further, as it has yet to put on a commercial during live television.
We wouldn’t put it out of the question, at least not yet.
Tesla was nice enough to hook us up with the new Model Y “Standard” trim for a few days, and while we’ll be sure to fill you in on the full experience in the coming days, there are a lot of differences we noticed right off the bat, which make the ownership experience different from the “Premium” configuration level.
I purchased a Model Y Long Range All-Wheel-Drive back in August and took delivery just two weeks later. Through the first three months of owning my car, I’ve come to love so many things about the Tesla experience.
I traded my ICE vehicle for a Tesla Model Y: here’s how it went
However, I was interested in experiencing the affordable trim and seeing whether I would miss any of the voided features of the “Premium” Model Y.
Through the first 24 hours, here are my first impressions of the Model Y Standard as a Premium trim level owner:
-->Overall Aesthetic
The lack of a light bar is not something that is a dealbreaker. In fact, I would argue that the Model Y Standard’s more traditional headlight design is just as pleasing from an aesthetic standpoint.
The car is great looking from top to bottom; there are not a substantial number of differences besides the lack of a lightbar on both the front and the back of the car.
Overall, it is a very sleek vehicle, but the major changes are obviously with the interior.
Interior Changes
This is where the big differences are, and some of the things I’ve gotten used to in the Premium are not included. If I didn’t have a Premium Model Y already, I’m not sure I’d miss some of the things that are not present in the Standard trim, but I believe I’d get annoyed with it.
First impressions:
✅ Interior is excellent. I definitely miss the additional storage already that is available in my Premium. I could definitely get over it though
✅ Noticeable step down in sound system. Long Time by Boston absolutely cranks in the Premium; it’s still very… https://t.co/JNWvxTd8p1

Storage
The Premium has a large storage compartment between the cupholders and the wireless charger, which is not present in the Standard trim. Instead, it is more like the Cybertruck, as there is a pass-through and floor storage.
I think that the pass-through is nice, but the additional storage is something I take advantage of, especially as someone who films Full Self-Driving videos, which requires hauling mounts, GoPros, and other accessories.
-->The sleekness of the Premium trim is also something I prefer; I really enjoy having the ability to close those compartments and cover the cupholders.
Obviously, this is a really trivial issue and not something that is substantially impactful from an ownership experience. If I weren’t already an owner, I am not sure I’d even have something to complain about.
Material Differences
The Premium trim seats are completely Vegan Leather, which I really do like, even as someone who doesn’t really love leather seats due to their temperature dependency.
The Standard trim features a Textile and Vegan hybrid, which has half of the seat a different material than the other.
The material is very similar to what I had in my previous car, a Bronco Sport. It was very durable, easy to clean, dried quickly, and hid a lot of things that leather does not, like oils from your skin, which constantly require attention to keep your interior looking fresh.
-->The wireless charger is also a different material, as the Premium features an Alcantara material on that. The Standard has a rubberized and textured backing, which looks good, too. They’re both more than suitable.
Other Missing Features
The Standard lacks a few minor things, most noticeably is the ambient lighting. The biggest change, however, and something I really miss, is the glass roof.
A lot of people told me that when I got my Model Y, I wouldn’t even notice the glass roof after a few weeks. That could not be further from the truth. I look out of it all the time, and it’s one of my family’s favorite parts of the car.
My Fiancè and I really love parking and watching Netflix when we pick food up, especially when it’s raining, because the glass roof gives such a great view.
We also loved it as Fall arrived, because it was great to look at the foliage.
-->Buy the Tesla.

Bigger Differences
There are also a handful of very noticeable differences from the overall cabin experience, especially with the sound system.
Much Weaker Sound System
The Model Y Standard has just 7 speakers and 1 amp, with no subwoofer. This is a significant step down from the 13-15 speakers in the Premium Long Range AWD Model Y, the 2 amps it comes with, and 1 subwoofer in the trunk.
-->I usually like to listen to Long Time by Boston to test out a sound system, and it was noticeably weaker in the Standard. It was missing a big portion of the umph that is provided by the Premium’s sound system.
Cabin Noise
It feels like the Cabin Noise is definitely more noticeable in the Standard, which is something I really love about my Model Y. It is able to dampen so much road noise from louder cars, and I don’t feel as if it is very quiet in the Standard.
This is perhaps the biggest make-or-break for me with this car. I truly have been spoiled by how quiet the cabin is in the Premium, and it’s due to the lack of acoustic-lined glass in the Standard.
I will be doing a more in-depth review of the Model Y Standard, especially with ride quality, later this week.

Tesla takes a step towards removal of Robotaxi service’s safety drivers
Tesla watchers are speculating that the implementation of in-camera data sharing could be a step towards the removal of the Robotaxi service’s safety drivers.
Tesla appears to be preparing for the eventual removal of its Robotaxi service’s safety drivers.
This was hinted at in a recent de-compile of the Robotaxi App’s version 25.11.5, which was shared on social media platform X.
In-cabin analytics
As per Tesla software tracker @Tesla_App_iOS, the latest update to the Robotaxi app featured several improvements. These include Live Screen Sharing, as well as a feature that would allow Tesla to access video and audio inside the vehicle.
According to the software tracker, a new prompt has been added to the Robotaxi App that requests user consent for enhanced in-cabin data sharing, which comprise Cabin Camera Analytics and Sound Detection Analytics. Once accepted, Tesla would be able to retrieve video and audio data from the Robotaxi’s cabin.
Video and audio sharing
A screenshot posted by the software tracker on X showed that Cabin Camera Analytics is used to improve the intelligence of features like request support. Tesla has not explained exactly how the feature will be implemented, though this might mean that the in-cabin camera may be used to view and analyze the status of passengers when remote agents are contacted.
-->Sound Detection Analytics is expected to be used to improve the intelligence of features like siren recognition. This suggests that Robotaxis will always be actively listening for emergency vehicle sirens to improve how the system responds to them. Tesla, however, also maintained that data collected by Robotaxis will be anonymous. In-cabin data will not be linked to users unless they are needed for a safety event or a support request.
Tesla watchers are speculating that the implementation of in-camera data sharing could be a step towards the removal of the Robotaxi service’s safety drivers. With Tesla able to access video and audio feeds from Robotaxis, after all, users can get assistance even if they are alone in the driverless vehicle.
