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 says texting and driving capability is coming ‘in a month or two’
“In the next month or two, we’re going to look at the safety statistics, but we’re going to allow you to text and drive, essentially.”
Tesla CEO Elon Musk said that within the next month or two, the company will be able to open the ability for people to text and drive because its Full Self-Driving suite will be robust enough to allow drivers to take their attention away from the road.
In its current state, Tesla Full Self-Driving is a supervised driver assistance suite that requires the vehicle operator to maintain control of the vehicle and pay attention to the road surroundings.
However, the company has been aiming to release a fully autonomous version of the Full Self-Driving suite for years, teasing its future potential and aiming to release a Level 5 suite as soon as possible.
CEO Elon Musk believes the company is on the cusp of something drastic, according to what he said at yesterday’s Annual Shareholder Meeting.
One thing Musk hinted at was that the company should be able to allow those sitting in the driver’s seat of their cars to text and drive “in the next month or two,” as long as the statistics look good.
He said:
“In the next month or two, we’re going to look at the safety statistics, but we’re going to allow you to text and drive, essentially.”
The company recently transitioned to its v14 Full Self-Driving suite, which is its most robust to date, and recently expanded to Cybertruck, completing its rollout across the vehicle lineup.
Currently, Tesla is running v14.1.5, and when major improvements are made, that second number will increase, meaning v14.2 will be the next substantial improvement.
Musk said that v14.3 will be when you can “pretty much fall asleep and wake up at your destination.”

We’ve heard a considerable amount of similar statements in the past, and Tesla owners have been conditioned to take some of these timeframes with autonomous driving with a grain of salt.
However, with the upgrades in FSD over the past few months, especially with the rollout of Robotaxi in Austin, which does not utilize anyone in the driver’s seat for local roads, it does not seem as if autonomy is that far off for Tesla.

Tesla Semi undergoes major redesign as dedicated factory preps for deliveries
The Semi has been one of the most anticipated products in the Tesla lineup due to the disruption it could cause in the trucking industry.
Tesla put its all-electric Semi truck through quite a major redesign as its dedicated factory for the vehicle is preparing for initial deliveries to the public starting next year.
The Semi has been one of the most anticipated products in the Tesla lineup due to the disruption it could cause in the trucking industry.
It has already been in numerous pilot programs for some pretty large companies over the past couple of years, PepsiCo. being one of them, and it is moving toward first deliveries to other companies sometime in 2026.
Yesterday at the 2025 Annual Shareholder Meeting, Tesla unveiled its new Semi design, which underwent a pretty significant facelift to match the aesthetic and vibe of the other vehicles in the company’s lineup.
Additionally, Tesla announced some other improvements, including changes to efficiency, and some other changes that we did not get details on yet.
The first change was to the design of the Semi, as Tesla adopted its blade-like light bar for the Class 8 truck, similar to the one that is used on the new Model Y and the Cybertruck:
There also appear to be a handful of design changes that help with aerodynamics, as its efficiency has increased to 1.7 kWh per mile.
Tesla also said it has an increased payload capability, which will help companies to haul more goods per trip.
All of these changes come as the company’s Semi Factory, which is located on the same property as its Gigafactory in Reno, Nevada, is just finishing up. In late October, it was shown that the Semi facility is nearly complete, based on recent drone imagery from factory observer HinrichsZane on X:
The factory will be capable of producing about 50,000 Tesla Semi units annually when it is completely ramped. The company has major plans to help get the Semi in more fleets across the United States.
Other entities are also working to develop a charging corridor for electric Class 8 trucks. The State of California was awarded $102 million to develop a charging corridor that spans from Washington to Southern California.
Another corridor is being developed that spans from Southern California to Texas, and 49 applicants won $636 million from the Department of Transportation for it.
Tesla requested funding for it, but was denied.
The Semi has been a staple in several companies’ fleets over the past few years, most notably that of Frito-Lay and PepsiCo., who have reported positive experiences thus far.
Musk said last year that the Semi had “ridiculous demand.”

Tesla Cybercab production starts Q2 2026, Elon Musk confirms
Elon Musk highlighted that the fully autonomous vehicle will be the first Tesla designed specifically for unsupervised self-driving.
Tesla CEO Elon Musk confirmed that production of the company’s autonomous Cybercab will begin in April 2026, and its production targets will be quite ambitious.
Speaking at Tesla’s 2025 Annual Shareholder Meeting, Musk highlighted that the fully autonomous vehicle will be the first Tesla designed specifically for unsupervised self-driving.
A robotaxi built for an autonomous world
Musk described the Cybercab as a clean-slate design optimized for autonomy, with no steering wheel, pedals, or side mirrors. “It’s very much optimized for the lowest cost per mile in an autonomous mode,” Musk said, adding that every Tesla produced in recent years already carries the hardware needed for full self-driving.
The Cybercab will be assembled at Giga Texas and will serve as the company’s flagship entry into the commercial robotaxi market. Musk emphasized that the project represents Tesla’s next evolutionary step in combining vehicle manufacturing, artificial intelligence, and mobility services.
One Cybercab every ten seconds
Musk reiterated that the Cybercab’s production process is more closely modeled on consumer electronics assembly than on traditional automotive manufacturing. This should pave the way for outputs that far exceed conventional automotive products.
“That production is happening right here in this factory, and we’ll be starting production in April next year. The manufacturing system is unlike any other car. The manufacturing system of the Cybercab, it’s closer to a high volume consumer electronics device than it is a car manufacturing line. So the net result is that I think we should be able to achieve, I think, ultimately, less than a 10-second cycle time, basically a unit every 10 seconds.
“What that would mean is you could get on a line that would normally produce, say, 500,000 cars a year at a one minute cycle time, Model Y. This would be maybe as much as 2 million or 3 million, maybe ultimately it’s theoretically possible to achieve a 5 million unit production line if you can get to the 5-second cycle time,” the CEO said.
