Tesla Model Y vs Model 3 casting comparison shows that legacy auto’s ‘soil-your-pants’ moment is at hand
Back in April 2018, automotive teardown expert Sandy Munro mentioned that if Tesla had contracted an experienced automaker to produce the early-production Model 3’s body, the electric car maker would have “wiped the floor with everybody.” This is because from the suspension down, the Model 3 was a stellar piece of engineering, despite its body having several issues.
Its electric motors were compact, powerful, and cost effective; its batteries are the best in the industry, and its driving dynamics give the impression that the vehicle was riding on rails. Munro noted that if Tesla had hit a home run with the Model 3’s “dinosaur technologies” like its welds and casts, even veteran auto giants like Toyota would appropriately be “crapping their pants.”
It has been nearly two years since Munro mentioned those words during an appearance at YouTube’s Autoline After Hours. Tesla has changed a lot since then, and the company has even released its latest vehicle, the Model Y crossover. Sharing 75% of the Model 3’s parts, the Model Y is designed as a mass-market electric vehicle, and one that can be even more disruptive as its sedan sibling.
Munro, for his part, has acquired and started a teardown of the all-electric crossover. And based on his findings thus far, it appears that Tesla’s “dinosaur technologies” have improved vastly since the Model 3. This is most evident in the rear casting utilized on the two vehicles.
One look at the Model Y and Model 3’s rear casts shows that the two vehicles are already worlds apart in terms of build quality and design. Munro noted that he did not like the Model 3’s rear casting at all, since it was also over-engineered, with about 100 parts utilized for its rear trunk.
In a way, the Model 3’s rear casting represented the hubris that Elon Musk has admitted to in the past, as it showed Tesla essentially trying to fix something that is not necessarily broken. The result of this was a lot of challenges for Tesla, and a lot of issues with the early-production Model 3’s rear casting.
The Model Y is an entirely different animal. The all-electric crossover features what could only be described as a giant rear casting that is the complete antithesis of the Model 3’s. It has few parts, its welds are consistent, and it features a trunk tub that is similar to those utilized by the world’s best automakers. It’s pretty much what the Model 3 could have been if Tesla was more experienced when they started building the all-electric sedan.
If the Model 3’s rear casting was an exercise in hubris, the Model Y’s rear cast is an exercise in humility. It showed that Tesla is flexible, and that it’s willing to learn, even if it meant abandoning its initial plans and starting from the ground up. Tesla evidently abandoned the early-production Model 3’s rear casting and trunk design. And it’s all the better for it.
A lot of this could be attributed to Elon Musk himself. Munro has noted in the past that he and the Tesla CEO had talked over the phone during his Model 3 teardown, where Musk explained the reasons behind some of the findings about the all-electric sedan. Munro’s firm later sent Tesla a pro bono list of over 200 suggestions that can improve the Model 3’s body.
These suggestions seem to have come to life in the Model Y. Granted, the teardown process for the all-electric crossover has only just begun. Still, several aspects of the vehicle, most notably its rear casting, shows that Tesla did learn from the Model 3, and it has become a much more mature automaker today. Other suggestions from the teardown expert were also applied to the Model Y’s other components, such as its wiring.
It should be noted that Tesla’s fast evolution is partly due to the company’s Silicon Valley startup roots. Startups are notorious for quick, drastic changes in direction, and workers at these companies are required to be tough and flexible. Tesla embodies this, making the company notoriously challenging to work for compared to conventional car companies like GM or Ford.
Yet despite this, Tesla has ranked consistently among the most attractive firms for engineering students. This is because in Tesla, conventional corporate bureaucracy is replaced with an open communication system that allows even interns to share their ideas with company executives. Some of the issues in the Model 3’s early production lines, for example, were addressed by interns, who were later hired full-time by Tesla.
The Model Y is a crossover, which means that it is competing in one of the fastest-growing segments in the auto industry today. With the Model Y, Tesla has the chance to make its biggest mark in the market yet. Fortunately, the electric car maker appears to have done its homework before it released its newest vehicle. One could even argue that Tesla released the Model Y at the perfect time. A mass-market all-electric vehicle that can disrupt the market of crossover SUVs requires a mature company, after all, and Tesla has only started to fit this bill recently.
Just two years ago, Munro mentioned that if the Model 3 had a properly-built body, veteran automakers like Toyota would be “crapping their pants” because of how outclassed they would be. With how the Model Y is turning out, it appears that legacy auto would be wise to keep some extra pairs of pants for the coming years, just in case.

Tesla CEO Elon Musk teased the insane capabilities of the next major Full Self-Driving update just hours after the company rolled out version 14.2 to owners.
Tesla Full Self-Driving v14.2 had some major improvements from the previous iteration of v14.1.x. We were on v14.1.7, the most advanced configuration of the v14.1 family, before Tesla transitioned us and others to v14.2.
However, Musk has said that the improvements coming in the next major update, which will be v14.3, will be where “the last big piece of the puzzle finally lands.”
14.3 is where the last big piece of the puzzle finally lands
— Elon Musk (@elonmusk) November 21, 2025
There were some major improvements with v14.2, most notably, Tesla seemed to narrow in on the triggers that caused issues with hesitation and brake stabbing in v14.1.x.
One of the most discussed issues with the past rollout was that of brake stabbing, where the vehicle would contemplate proceeding with a route as traffic was coming from other directions.
We experienced it most frequently at intersections, especially four-way stop signs.
Elon Musk hints at when Tesla can fix this FSD complaint with v14
In our review of it yesterday, it was evident that this issue had been resolved, at least to the extent that we had no issues with it in a 62-minute drive, which you can watch here.
Some owners also reported a more relaxed driver monitoring system, which is something Tesla said it was working on as it hopes to allow drivers to text during operation in the coming months. We did not test this, as laws in Pennsylvania prohibit the use of phones at any time due to the new Paul Miller’s Law, which took effect earlier this year.
However, the improvements indicate that Tesla is certainly headed toward a much more sentient FSD experience, so much so that Musk’s language seems to be more indicative of a more relaxed experience in terms of overall supervision from the driver, especially with v14.3.
Musk did not release or discuss a definitive timeline for the release of v14.3, especially as v14.2 just rolled out to Early Access Program (EAP) members yesterday. However, v14.1 rolled out to Tesla owners just a few weeks ago in late 2025. There is the potential that v14.3 could be part of the coming Holiday Update, or potentially in a release of its own before the New Year.
Tesla rolled out Full Self-Driving version 14.2 yesterday to members of the Early Access Program (EAP). Expectations were high, and Tesla surely delivered.
With the rollout of Tesla FSD v14.2, there were major benchmarks for improvement from the v14.1 suite, which spanned across seven improvements. Our final experience with v14.1 was with v14.1.7, and to be honest, things were good, but it felt like there were a handful of regressions from previous iterations.
While there were improvements in brake stabbing and hesitation, we did experience a few small interventions related to navigation and just overall performance. It was nothing major; there were no critical takeovers that required any major publicity, as they were more or less subjective things that I was not particularly comfortable with. Other drivers might have been more relaxed.
With v14.2 hitting our cars yesterday, there were a handful of things we truly noticed in terms of improvement, most notably the lack of brake stabbing and hesitation, a major complaint with v14.1.x.
However, in a 62-minute drive that was fully recorded, there were a lot of positives, and only one true complaint, which was something we haven’t had issues with in the past.
The Good
Lack of Brake Stabbing and Hesitation
Perhaps the most notable and publicized issue with v14.1.x was the presence of brake stabbing and hesitation. Arriving at intersections was particularly nerve-racking on the previous version simply because of this. At four-way stops, the car would not be assertive enough to take its turn, especially when other vehicles at the same intersection would inch forward or start to move.
This was a major problem.
However, there were no instances of this yesterday on our lengthy drive. It was much more assertive when arriving at these types of scenarios, but was also more patient when FSD knew it was not the car’s turn to proceed.
Can report on v14.2 today there were ZERO instances of break stabbing or hesitation at intersections today
It was a significant improvement from v14.1.x
— TESLARATI (@Teslarati) November 21, 2025
This improvement was the most noticeable throughout the drive, along with fixes in overall smoothness.
Speed Profiles Seem to Be More Reasonable
There were a handful of FSD v14 users who felt as if the loss of a Max Speed setting was a negative. However, these complaints will, in our opinion, begin to subside, especially as things have seemed to be refined quite nicely with v14.2.
Freeway driving is where this is especially noticeable. If it’s traveling too slow, just switch to a faster profile. If it’s too fast, switch to a slower profile. However, the speeds seem to be much more defined with each Speed Profile, which is something that I really find to be a huge advantage. Previously, you could tell the difference in speeds, but not in driving styles. At times, Standard felt a lot like Hurry. Now, you can clearly tell the difference between the two.
It seems as if Tesla made a goal that drivers should be able to tell which Speed Profile is active if it was not shown on the screen. With v14.1.x, this was not necessarily something that could be done. With v14.2, if someone tested me on which Speed Profile was being used, I’m fairly certain I could pick each one.
Better Overall Operation
I felt, at times, especially with v14.1.7, there were some jerky movements. Nothing that was super alarming, but there were times when things just felt a little more finicky than others.
v14.2 feels much smoother overall, with really great decision-making, lane changes that feel second nature, and a great speed of travel. It was a very comfortable ride.
The Bad
Parking
It feels as if there was a slight regression in parking quality, as both times v14.2 pulled into parking spots, I would have felt compelled to adjust manually if I were staying at my destinations. For the sake of testing, at my first destination, I arrived, allowed the car to park, and then left. At the tail-end of testing, I walked inside the store that FSD v14.2 drove me to, so I had to adjust the parking manually.
This was pretty disappointing. Apart from parking at Superchargers, which is always flawless, parking performance is something that needs some attention. The release notes for v14.2. state that parking spot selection and parking quality will improve with future versions.

However, this was truly my only complaint about v14.2.

SpaceX issues statement on Starship V3 Booster 18 anomaly
The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX has issued an initial statement about Starship Booster 18’s anomaly early Friday. The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX’s initial comment
As per SpaceX in a post on its official account on social media platform X, Booster 18 was undergoing gas system pressure tests when the anomaly happened. Despite the nature of the incident, the company emphasized that no propellant was loaded, no engines were installed, and personnel were kept at a safe distance from the booster, resulting in zero injuries.
“Booster 18 suffered an anomaly during gas system pressure testing that we were conducting in advance of structural proof testing. No propellant was on the vehicle, and engines were not yet installed. The teams need time to investigate before we are confident of the cause. No one was injured as we maintain a safe distance for personnel during this type of testing. The site remains clear and we are working plans to safely reenter the site,” SpaceX wrote in its post on X.
Incident and aftermath
Livestream footage from LabPadre showed Booster 18’s lower half crumpling around the liquid oxygen tank area at approximately 4:04 a.m. CT. Subsequent images posted by on-site observers revealed extensive deformation across the booster’s lower structure. Needless to say, spaceflight observers have noted that Booster 18 would likely be a complete loss due to its anomaly.
Booster 18 had rolled out only a day earlier and was one of the first vehicles in the Starship V3 program. The V3 series incorporates structural reinforcements and reliability upgrades intended to prepare Starship for rapid-reuse testing and eventual tower-catch operations. Elon Musk has been optimistic about Starship V3, previously noting on X that the spacecraft might be able to complete initial missions to Mars.
