Tesla’s Model 3 electric motor is a clever mystery box, says auto experts

Model 3 drivetrain.

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 makes two big interior changes to several Model Y vehicles

Tesla has made two big interior changes to several Model Y vehicles in its lineup, and the changes come just as the new model year begins production.

Last year, Tesla launched the Model Y Standard, which separated the previous models into the “Premium” category. The Standard vehicles lack several features, including more premium interior materials, acoustic-lined glass, and storage.

@teslarati There are some BIG differences between the Tesla Model Y Standard and Tesla Model Y Premium #tesla #teslamodely ♬ Sia – Xeptemper

The Model Y “Premium” trims are now getting several new upgrades, which come after the company launched a seven-seat configuration of the vehicle last night in the North American market for an upcharge of $2,500.

The new Model Y seven-seat configuration did not come with just an additional row of seating; it also came with a slew of other goodies that now come standard and were previously only available on the Model Y Performance, which was launched late last year.

All Black Headliner

The new Tesla Model Y Premium trims will now come standard with a black headliner, something that many owners have been requesting for some time.

The previous grey headliner and trim within the vehicle is now gone; it will be all black on all of the Premium trims from here on out, a welcome change:

Larger and Higher Resolution Center Touchscreen

The center touchscreen in the new Model Y Premium configuration is now larger and has a higher resolution than the previous version.

In last year’s Model Y configurations (apart from the Performance), the center touchscreen was 15.4″. Now, Tesla has decided to go with the 16″ version across all Premium trims, which is a nice step up. It was nice to see this in the Performance, but it is really great to see Tesla include this in the Model Y’s more Premium trim levels.

Tesla Model Y Seven Seater

Tesla launched the latest iteration of the seven-seater for the Model Y on Monday night. Traditionally, the Model Y seats five passengers in total, but there were calls for a more spacious version several years ago.

Tesla released it, but it was extremely tight in the back, basically reserving those back seats for only small people or children.

The new configuration looks to be slightly more spacious in the third row, but not as much space as most would require or want. Instead,

Lufthansa Group has announced a partnership with Starlink that will bring high-speed internet connectivity to every aircraft across all its carriers. 

This means that aircraft across the group’s brands, from Lufthansa, SWISS, and Austrian Airlines to Brussels Airlines, would be able to enjoy high-speed internet access using the industry-leading satellite internet solution.

Starlink in-flight internet

Starlink’s low-Earth orbit satellites are expected to provide significantly higher bandwidth and lower latency than traditional in-flight Wi-Fi, which should enable streaming, online work, and other data-intensive applications for passengers during flights.

Starlink-powered internet is expected to be available on the first commercial flights as early as the second half of 2026. The rollout will continue through the decade, with the entire Lufthansa Group fleet scheduled to be fully equipped with Starlink by 2029. Once complete, no other European airline group will operate more Starlink-connected aircraft.

Free high-speed access

As part of the initiative, Lufthansa Group will offer the new high-speed internet free of charge to all status customers and Travel ID users, regardless of cabin class. Chief Commercial Officer Dieter Vranckx shared his expectations for the program.

“In our anniversary year, in which we are celebrating Lufthansa’s 100th birthday, we have decided to introduce a new high-speed internet solution from Starlink for all our airlines. The Lufthansa Group is taking the next step and setting an essential milestone for the premium travel experience of our customers. 

“Connectivity on board plays an important role today, and with Starlink, we are not only investing in the best product on the market, but also in the satisfaction of our passengers,” Vranckx said.

Tesla locks in Elon Musk’s top problem solver as it enters its most ambitious era

The generous equity award was disclosed by the electric vehicle maker in a recent regulatory filing.

Tesla has granted Senior Vice President of Automotive Tom Zhu more than 520,000 stock options, tying a significant portion of his compensation to the company’s long-term performance. 

The generous equity award was disclosed by the electric vehicle maker in a recent regulatory filing.

Tesla secures top talent

According to a Form 4 filing with the U.S. Securities and Exchange Commission, Tom Zhu received 520,021 stock options with an exercise price of $435.80 per share. Since the award will not fully vest until March 5, 2031, Zhu must remain at Tesla for more than five years to realize the award’s full benefit.

Considering that Tesla shares are currently trading at around the $445 to $450 per share level, Zhu will really only see gains in his equity award if Tesla’s stock price sees a notable rise over the years, as noted in a Sina Finance report.

Still, even at today’s prices, Zhu’s stock award is already worth over $230 million. If Tesla reaches the market cap targets set forth in Elon Musk’s 2025 CEO Performance Award, Zhu would become a billionaire from this equity award alone.

Tesla’s problem solver

Zhu joined Tesla in April 2014 and initially led the company’s Supercharger rollout in China. Later that year, he assumed the leadership of Tesla’s China business, where he played a central role in Tesla’s localization efforts, including expanding retail and service networks, and later, overseeing the development of Gigafactory Shanghai.

Zhu’s efforts helped transform China into one of Tesla’s most important markets and production hubs. In 2023, Tesla promoted Zhu to Senior Vice President of Automotive, placing him among the company’s core global executives and expanding his influence beyond China. He has since garnered a reputation as the company’s problem solver, being tapped by Elon Musk to help ramp Giga Texas’s vehicle production. 

With this in mind, Tesla’s recent filing seems to suggest that the company is locking in its top talent as it enters its newest, most ambitious era to date. As could be seen in the targets of Elon Musk’s 2025 pay package, Tesla is now aiming to be the world’s largest company by market cap, and it is aiming to achieve production levels that are unheard of. Zhu’s talents would definitely be of use in this stage of the company’s growth.
