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.

IM Motors co-CEO apologizes to Tesla China over FUD comments
Liu said later investigations showed the accident was not caused by a brake failure on the Tesla’s part, contrary to his initial comments.
Liu Tao, co-CEO of IM Motors, has publicly apologized to Tesla China for comments he made in 2022 suggesting a Tesla vehicle was defective following a fatal traffic accident in Chaozhou, China.
Liu said later investigations showed the accident was not caused by a brake failure on the Tesla’s part, contrary to his initial comments.
IM Motors co-CEO issues apology
Liu Tao posted a statement addressing remarks he made following a serious traffic accident in Chaozhou, Guangdong province, in November 2022, as noted in a Sina News report. Liu stated that based on limited public information at the time, he published a Weibo post suggesting a safety issue with the Tesla involved in the crash. The executive clarified that his initial comments were incorrect.
“On November 17, 2022, based on limited publicly available information, I posted a Weibo post regarding a major traffic accident that occurred in Chaozhou, suggesting that the Tesla product involved in the accident posed a safety hazard. Four hours later, I deleted the post. In May 2023, according to the traffic police’s accident liability determination and relevant forensic opinions, the Chaozhou accident was not caused by Tesla brake failure.
“The aforementioned findings and opinions regarding the investigation conclusions of the Chaozhou accident corrected the erroneous statements I made in my previous Weibo post, and I hereby clarify and correct them. I apologize for the negative impact my inappropriate remarks made before the facts were ascertained, which caused Tesla,” Liu said.
Investigation and court findings
The Chaozhou accident occurred in Raoping County in November 2022 and resulted in two deaths and three injuries. Video footage circulated online at the time showed a Tesla vehicle accelerating at high speed and colliding with multiple motorcycles and bicycles. Reports indicated the vehicle reached a speed of 198 kilometers per hour.
The incident drew widespread attention as the parties involved provided conflicting accounts and investigation details were released gradually. Media reports in early 2023 said investigation results had been completed, though the vehicle owner requested a re-investigation, delaying the issuance of a final liability determination.
The case resurfaced later in 2023 following a defamation lawsuit filed by Tesla China against a media outlet. According to a court judgment cited by Shanghai Securities News, forensic analysis determined that the fatal accident was unrelated to any malfunction on the Tesla’s braking or steering systems. The court also ruled that the media outlet must publish an apology, address the negative impact on Tesla China’s reputation, and pay a penalty of 30,000 yuan.

SpaceX is exploring a “Starlink Phone” for direct-to-device internet services: report
The update was reportedly shared to Reuters by people familiar with the matter.
SpaceX is reportedly exploring new products tied to Starlink, including a potential Starlink-branded phone.
The update was reportedly shared to Reuters by people familiar with the matter.
A possible Starlink Phone
As per Reuters’ sources, SpaceX has reportedly discussed building a mobile device designed to connect directly to the Starlink satellite constellation. Details about the potential device and its possible release are still unclear, however.
SpaceX has dabbled with mobile solutions in the past. The company has partnered with T-Mobile to provide Starlink connectivity to existing smartphones. And last year, SpaceX initiated a $19.6 billion purchase of satellite spectrum from EchoStar.
Elon Musk did acknowledge the idea of a potential mobile device recently on X, writing that a Starlink phone is “not out of the question at some point.” Unlike conventional smartphones, however, Musk described a device that is “optimized purely for running max performance/watt neural nets.”
Starlink and SpaceX’s revenue
Starlink has become SpaceX’s dominant commercial business. Reuters’ sources claimed that the private space company generated roughly $15–$16 billion in revenue last year, with about $8 billion in profit. Starlink is estimated to have accounted for 50% to 80% of SpaceX’s total revenue last year.
SpaceX now operates more than 9,500 Starlink satellites and serves over 9 million users worldwide. About 650 satellites are already dedicated to SpaceX’s direct-to-device initiative, which aims to eventually provide full cellular coverage globally.
Future expansion of Starlink’s mobile capabilities depends heavily on Starship, which is designed to launch larger batches of upgraded Starlink satellites. Musk has stated that each Starship launch carrying Starlink satellites could increase network capacity by “more than 20 times.”

FCC accepts SpaceX filing for 1 million orbital data center plan
The move formally places SpaceX’s “Orbital Data Center” concept into the FCC’s review process.
The Federal Communications Commission (FCC) has accepted SpaceX’s filing for a new non-geostationary orbit (NGSO) satellite system of up to one million spacecraft and has opened the proposal for public comment.
The move formally places SpaceX’s “Orbital Data Center” concept into the FCC’s review process, marking the first regulatory step for the ambitious space-based computing network.
FCC opens SpaceX’s proposal for comment
In a public notice, the FCC’s Space Bureau stated that it is accepting SpaceX’s application to deploy a new non-geostationary satellite system known as the “SpaceX Orbital Data Center system.” As per the filing, the system would consist of “up to one million satellites” operating at altitudes between 500 and 2,000 kilometers, using optical inter-satellite links for data transmission.
The FCC notice described the proposal as a long-term effort. SpaceX wrote that the system would represent the “first step towards becoming a Kardashev II-level civilization – one that can harness the Sun’s full power.” The satellites would rely heavily on high-bandwidth optical links and conduct telemetry, tracking, and command operations, with traffic routed through space-based laser networks before being sent to authorized ground stations.
FCC Chairman Brendan Carr highlighted the filing in a post on X, noting that the Commission is now seeking public comment on SpaceX’s proposal. Interested parties have until early March to submit comments.
What SpaceX is proposing to build
As per the FCC’s release, SpaceX’s orbital data center system would operate alongside its existing and planned Starlink constellations. The FCC notice noted that the proposed satellites may connect not only with others in the new system, but also with satellites in SpaceX’s first- and second-generation Starlink networks.
The filing also outlined several waiver requests, including exemptions from certain NGSO milestone and surety bond requirements, as well as flexibility in how orbital planes and communication beams are disclosed, as noted in a Benzinga report. SpaceX noted that these waivers are necessary to support the scale and architecture of the proposed system.
As noted in coverage of the filing, the proposal does not represent an immediate deployment plan, but rather a framework for future space-based computing infrastructure. SpaceX has discussed the idea of moving energy-intensive computing, such as AI workloads, into orbit, where continuous solar power and large physical scale could reduce constraints faced on Earth.
