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 arsonist who burned Cybertruck sees end of FAFO journey
The man has now reached the “Find Out” stage.
A Mesa, Arizona man has been sentenced to five years in federal prison for setting fire to a Tesla location and vehicle in a politically motivated arson attack, federal prosecutors have stated.
The April 2025 incident destroyed a Tesla Cybertruck, endangered first responders, and triggered mandatory sentencing under federal arson laws.
A five-year sentence
U.S. District Judge Diane J. Humetewa sentenced Ian William Moses, 35, of Mesa, Arizona, to 5 years in prison followed by 3 years of supervised release for maliciously damaging property and vehicles by means of fire. Moses pleaded guilty in October to all five counts brought by a federal grand jury. Restitution will be determined at a hearing scheduled for April 13, 2026.
As per court records, surveillance footage showed Moses arriving at a Tesla store in Mesa shortly before 2 a.m. on April 28, 2025, carrying a gasoline can and backpack. Investigators stated that he placed fire starter logs near the building, poured gasoline on the structure and three vehicles, and ignited the fire. The blaze destroyed a Tesla Cybertruck. Moses fled the scene on a bicycle and was arrested by Mesa police about a quarter mile away, roughly an hour later.
Authorities said Moses was still wearing the same clothing seen on camera at the time of his arrest and was carrying a hand-drawn map marking the dealership’s location. Moses also painted the word “Theif” on the walls of the Tesla location, prompting jokes from social media users and Tesla community members.
The “Finding Out” stage
U.S. Attorney Timothy Courchaine noted that Moses’ sentence reflects the gravity of his crime. He also highlighted that arson is never acceptable.
“Arson can never be an acceptable part of American politics. Mr. Moses’ actions endangered the public and first responders and could have easily turned deadly. This five-year sentence reflects the gravity of these crimes and makes clear that politically fueled attacks on Arizona’s communities and businesses will be met with full accountability.”
Maricopa County Attorney Rachel Mitchell echoed the same sentiments, stating that regardless of Moses’ sentiments towards Elon Musk, his actions are not defensible.
“This sentence sends a clear message: violence and intimidation have no place in our community. Setting fire to a business in retaliation for political or personal grievances is not protest, it is a crime. Our community deserves to feel safe, and this sentence underscores that Maricopa County will not tolerate political violence in any form.”

Tesla says its Texas lithium refinery is now operational and unlike anything in North America
Elon Musk separately described the site as both the most advanced and the largest lithium refinery in the United States.
Tesla has confirmed that its Texas lithium refinery is now operational, marking a major milestone for the company’s U.S. battery supply chain. In a newly released video, Tesla staff detailed how the facility converts raw spodumene ore directly into battery-grade lithium hydroxide, making it the first refinery of its kind in North America.
Elon Musk separately described the site as both the most advanced and the largest lithium refinery in the United States.
A first-of-its-kind lithium refining process
In the video, Tesla staff at the Texas lithium refinery near Corpus Christi explained that the facility processes spodumene, a lithium-rich hard-rock ore, directly into battery-grade lithium hydroxide on site. The approach bypasses intermediate refining steps commonly used elsewhere in the industry.
According to the staff, spodumene is processed through kilns and cooling systems before undergoing alkaline leaching, purification, and crystallization. The resulting lithium hydroxide is suitable for use in batteries for energy storage and electric vehicles. Tesla employees noted that the process is simpler and less expensive than traditional refining methods.
Staff at the facility added that the process eliminates hazardous byproducts typically associated with lithium refining. “Our process is more sustainable than traditional methods and eliminates hazardous byproducts, and instead produces a co-product named anhydrite, used in concrete mixes,” an employee noted.
Musk calls the facility the largest lithium refinery in America
The refinery’s development timeline has been very impressive. The project moved from breaking ground in 2023 to integrated plant startup in 2025 by running feasibility studies, design, and construction in parallel. This compressed schedule enabled the fastest time-to-market for a refinery using this type of technology. This 2026, the facility has become operational.
Elon Musk echoed the significance of the project in posts on X, stating that “the largest Lithium refinery in America is now operational.” In a separate comment, Musk described the site as “the most advanced lithium refinery in the world” and emphasized that the facility is “very clean.”
By bringing large-scale lithium hydroxide production online in Texas, Tesla is positioning itself to reduce reliance on foreign refining capacity while supporting its growth in battery and vehicle production. The refinery also complements Tesla’s nascent domestic battery manufacturing efforts, which could very well be a difference maker in the market.

Tesla Optimus V3 gets early third-party feedback, and it’s eye-opening
Jason Calacanis’ remarks, which were shared during a discussion at CES 2026, offered one of the first third-party impressions of the yet-to-be-unveiled robot
Angel investor and entrepreneur Jason Calacanis shared some insights after he got an early look at Tesla’s upcoming Optimus V3. His remarks, which were shared during a discussion at CES 2026, offered one of the first third-party impressions of the yet-to-be-unveiled robot.
Calacanis’ comments were shared publicly on X, and they were quite noteworthy.
The angel investor stated that he visited Tesla’s Optimus lab on a Sunday morning and observed that the place was buzzing with energy. The investor then shared a rare, shocking insight. As per Calacanis, Optimus V3 will be so revolutionary that people will probably not even remember that Tesla used to make cars in the future.
“I don’t want to name drop, but two Sundays ago, I went to Tesla with Elon and I went and visited the Optimus lab. There were a large number of people working on a Sunday at 10 a.m. and I saw Optimus 3. I can tell you now, nobody will remember that Tesla ever made a car,” he noted.
The angel investor also reiterated the primary advantage of Optimus, and how it could effectively change the world.
“They will only remember the Optimus and that he is going to make a billion of those, and it is going to be the most transformative technology product ever made in the history of humanity, because what LLMs are gonna enable those products to do is understand the world and then do things in the world that we don’t want to do. I believe there will be a 1:1 ratio of humans to Optimus, and I think he’s already won,” he said.
While Calacanis’ comments were clearly opinion-driven, they stood out as among the first from a non-Tesla employee about Optimus V3. Considering his reaction to the humanoid robot, perhaps Elon Musk’s predictions for Optimus V3 might not be too far-fetched at all.
Tesla has been careful with its public messaging around Optimus V3’s development stage. Musk has previously stated on X that Optimus V3 has not yet been revealed publicly, clarifying that images and videos of the robot online still show Optimus V2 and V2.5, not the next-generation unit. As for Calacanis’ recent comments, however, Musk responded with a simple “Probably true” in a post on X.
