Sandy Munro, a teardown specialist and auto industry veteran, is releasing the results of a study he conducted with battery expert Mark Ellis comparing the motors inside four electric vehicles, one of which was a Tesla Model 3. Despite analyzing the vehicle for a long time, the auto expert states that there are still mysteries that he is yet to uncover on the electric sedan.
“The Tesla has a lot of stuff hidden. The Tesla is a big mystery. It’s not obvious sometimes what clever things they’ve done, ” he commented about the California-based car maker’s motor in a recent interview summarized by Industry Week. “There’s mysteries every day. We thought we were clever, but we’re not that clever.”
One of the clever features Munro and Ellis discovered in their Model 3 teardown was the disconnect device for the high voltage. “It’s not really a fuse…It’s like a little explosion. If the car rolls over, they have a little disconnect that blows up, [cutting] all the power to everything and that way you don’t have an electric nightmare,” he revealed. Also, the inner magnets of the Model 3 motor were found to be under a lot of stress, which is not something other manufacturers have learned to do in high volume production. “We’ve talked to lots of magnet manufacturers, but this might be another one of these made-in-Tesla kind of deals. They make a lot of stuff in-house,” Munro guessed.
Another innovation that impressed the teardown team was how advanced the inverter/convertor device was that provides power to the motor, particularly in the use of silicon carbide on the devices’ integrated circuits. “It creates a lot less heat and is a lot faster than the Chevy and BMW,” Ellis added to the discussion. “Silicon carbide is the latest and greatest and Tesla so far is the only vehicle out there with it.” Munro and Ellis further noted the high level of tech Tesla’s motor contained, all while being considerably smaller than the competition.
The study will be released in a few weeks and also includes detailed information about the motors inside the Chevy Bolt, BMW i3, and Jaguar I-Pace. Munro had very positive things to say about Tesla’s technology, but the electric vehicles produced by industry giants did not receive quite the same accolades. “It looks like the other guys just went around and glued together whatever they could find off the shelf,” Munro jabbed at Tesla’s competition.
The BMW i3 was hit particularly hard and cited as the heaviest, most expensive, and very inefficient overall. “It’s not designed for… I don’t know what it’s designed for, really,” Munro swiped in the interview. “While everything on Tesla is…very, very efficient engineering.” Munro still isn’t sold on the Model 3 body, though, and takes issue with the complexity of the process it takes to manufacture it thanks to the number of parts, materials, and fastenings involved.
-->Munro has a history of strong opinions on Tesla’s car intended for the mass market. After completing an initial teardown of a 2017 version of the vehicle, he infamously commented that the car’s panel gaps could be seen “from Mars” among other very critical remarks about the way the car was manufactured. Tesla eventually issued a statement in response to the criticisms, indicating that significant improvements had been made to its Model 3 manufacturing process which would render moot many of the issues identified.
Once the Model 3 teardown was complete, Munro later admitted to eating “a lot of crow” in response to the technology installed and implemented throughout the car. He praised the Model 3 battery pack and the way it handles on the road, in particular, and also estimated Tesla was turning a 30% profit on the vehicle. Munro ultimately concluded that everything from the car’s suspension and down was perfect, but everything about its bodywork was questionable.
While the study Sandy Munro and Mark Ellis have conducted has not yet been released, from the sounds of it, crow seems to have still been on the menu for Tesla’s inner workings while old criticisms still stand about its outer packaging.
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.
