Tesla Model 3’s body structure is a strategic blend of aluminum and ultra high-strength steel

Published

on

New photos from Tesla Model 3’s Body Repair Tech Note reveal a metal composition for the vehicle’s structure that strikes a perfect balance between world class safety and cost effectiveness.

One might recall Tesla CEO Elon Musk giving a tonque-in-cheek response about Model 3’s 5-star safety rating during a speech in Fremont, California. “The Volvo [S60] is arguably the second safest car in the world”, said Musk while alluding to the fact that Model 3 takes top honors for being the safest car in the world.

Photos posted to Twitter and shared on Reddit illustrate just how Tesla has been able to achieve a Model 3 body structure design that’s lightweight and has unparalleled strength at an entry level price point.

Looking at a front quarter exploded view of the Model 3 body, one can see the various compositions of steel the Tesla engineers used across the machine-stamped, multi-layer structure.

Tesla uses three different grades of steel, from mild steel used on the outer body structure where it’s designed to absorb initial impacts, and high-strength, to ultra high-strength used in the vehicle’s core. For instance, the A-pillar and B-pillar (noted in red on the graphic) is fabricated from ultra high-strength steel in order to provide maximum rollover protection. Model 3’s front frame rail is a composition between high-strength and ultra high-strength steel, and serves as the main support for the front “crumple zone”.

Tesla Model 3’s body repair manual notes that “Structural Pulling” is not allowed, meaning that any structural component that’s welded, weld-bonded, riveted, or rivet-bonded to the vehicle can not undergo a process wherein the straightening of structural parts are facilitated through a hydraulic pulling machine. Doing so would compromise the yield strength of the metals being used.

 

Also noted in the Model 3 structural diagram is the “underbelly” that serves as the main support for Model 3’s skateboard style battery pack, similar to what’s used in its older Model S and Model X siblings. The entire underside of the vehicle is fabricated from high-strength steel.

Side impact safety on the Model 3 is bolstered by a fully fortified closed steel structure in ultra high-strength steel. Looking at the crash test video showing a side-pole impact test performed on Tesla’s Model 3 and Volvo’s S60, one can easily see the level of deformity the Volvo has over the Model 3.

Lastly, lightweight aluminum is introduced in areas of the body structure that are less susceptible to accidental impact such as the trunk floor and wheel wells. Using aluminum helps Model 3 maintain a relatively light curb weight of 3,549 lbs. for the standard version and 3,814 lbs. for the Long Range Model 3 with larger (and heavier) battery pack.

All in all, Tesla’s use of various steels and aluminum in Model 3’s body structure can be seen as a learning experience and first iteration towards even more affordable and higher volume production down the road – Model Y.

Tesla Model Y L might not come to the U.S., and it’s a missed opportunity

The Model Y L has a variety of big changes that would be advantageous for the U.S. market, including a longer wheelbase, more comfortable seats, a third row that appears to be more spacious than Tesla’s six-seat Model Y that it previously offered, B-Pillar vents for rear passengers, and more.

Tesla’s new Model Y L might not come to the U.S., CEO Elon Musk said this morning.

It’s a missed opportunity, and I’m not the only one who feels this way.

In the past, I have personally written a handful of articles about what Tesla owners have been wanting in the United States: a full-sized SUV, or at least a vehicle that is larger than the Model Y but less of a crossover than the Model X.

Tesla is missing one type of vehicle in its lineup and fans want it fast

The only thing that Tesla has announced that even slightly matches this sort of idea is the Robovan, which is, optimistically, several years off because it lacks a steering wheel and pedals and will require Full Self-Driving to be fully autonomous.

Even if Tesla launches FSD next year, it will take a year or two to figure out manufacturing, go through regulatory hurdles with the EPA, and eventually enter mass production for customers.

The Model Y L has a variety of big changes that would be advantageous for the U.S. market, including a longer wheelbase, more comfortable seats, a third row that appears to be more spacious than Tesla’s six-seat Model Y that it previously offered, B-Pillar vents for rear passengers, and more.

However, Musk said it won’t come to the U.S. until next year, and that it “might not ever, given the advent of self-driving in America.”

To be blunt, I’m not sure if I truly believe that Musk thinks the Model Y L won’t come to the U.S. Some believe he said this to not Osborne Effect Model Y sales here, which seems more likely than anything.

Tesla Model Y L gets disappointingly far production date in the United States

People have been buying the Model Y for two years more than any other car in the world. To act as if many families would not appreciate the extra space seems very strange; a big complaint with the Model Y is that it simply does not fit larger families.

If you have four kids, you’re forced into the Model X, which might be too expensive for some families, as it starts at $79,990.

While Tesla’s focus is undoubtedly on autonomy, it is important to remember that some people still really enjoy the act of driving their cars. Tesla has worked very hard to create a fun and sporty driving experience, especially in the new Model Y. Many consumers, including myself, like to take advantage of that.

Autonomy might eventually take over human driving completely, but in the near term, it does not seem as if that is the case. Even if someone were interested in never driving again, this longer and more spacious Model Y L would be an ideal option for American families that need the room for at least six passengers.

Quite a few big names in the Tesla community share this sentiment:

More than likely, Musk does not want to announce a more attractive option than the current Model Y, as many consumers would likely wait a year or two for the L in an effort to have more space.

In all honesty, I see the Model Y L coming to the United States, as it truly fits the bill as an ideal car for the modern American family.

Tesla’s Elon Musk shares optimistic teaser about FSD V14: “Feels sentient”

FSD V14 is arguably the second biggest update to Tesla AI/Autopilot after the release of V12, Musk wrote.

Tesla CEO Elon Musk has provided a rather exciting teaser about the capabilities of Full Self-Driving’s (FSD) upcoming V14 update. 

As per Musk, V14 is arguably the second biggest update to Tesla AI/Autopilot after the release of V12, which started its initial rollout to Tesla employees way back November 2023.

Tesla FSD V14

Elon Musk has been teasing the capabilities of FSD V14 in recent weeks. Earlier this month, the CEO shared that FSD V14 will feature a 10X higher parameter count, and it will also nag drivers significantly less than the system’s current iteration. While FSD V14 is not Unsupervised FSD, which is being used in the Austin Robotaxi pilot, it is expected to be a significant improvement nonetheless.

“The FSD release in about 6 weeks will be a dramatic gain with a 10X higher parameter count and many other improvements. It’s going through training & testing now. Once we confirm real-world safety of FSD 14, which we think will be amazing, the car will nag you much less,” Musk wrote in his post.

“Feels sentient”

Musk recently shared some more details about FSD V14 on X. In response to a video of a William Blair analyst who mentioned that Tesla’s Robotaxi service felt a lot more like a person was driving it compared to Waymo’s robotic maneuvers, Musk noted that “Version 14 of Tesla self-driving fells sentient.”

Musk also clarified that the system that the William Blair analyst experienced was Version 13, so the system’s performance will definitely get even better. “He was just on version 13. Version 14 is the second biggest update to Tesla AI/Autopilot ever after V12. It feels alive,” Musk wrote in his post.

Musk’s comments bode well for the rollout of FSD V14. So far, FSD has reached a point where drivers and passengers have commented that the system already operates a vehicle in a very cautious and humanlike manner. Having a system that feels “sentient,” as the CEO noted, would most definitely be game-changing.

Tesla has officially rolled out the Model Y L, a six-seat variant of its best-selling SUV, across all showrooms in China, and it is getting a lot of attention from potential buyers.

Images and videos from Tesla stores in China show crowds of people checking out the recently released extended wheelbase all-electric crossover.

Model Y L details

The vehicle, which carries a starting price of RMB 339,000 ($47,180), went live in Tesla China’s configurator this week. Deliveries are scheduled to begin in September, and early media reviews have already been released following the lifting of an embargo.

Unlike a full model refresh, the Model Y L is positioned as a new variant within the existing Model Y lineup. It joins the five-seat rear-wheel drive (RWD) and long-range all-wheel drive (AWD) Model Y variants currently available in China.

The six-seat Model Y L features dual-motor all-wheel drive, a 0–100 km/h time of 4.5 seconds, and an 82.0-kWh battery pack from LG Energy Solution. Its CLTC-rated range reaches 751 km, the highest among Tesla’s Model Y trims.

So far, the reception to the Model Y L appears to be very warm, with photos and videos of stores in locations such as Shanghai and Shenyang showing numerous people checking out the recently released vehicle. Reports from industry watchers in China also suggest that Tesla received about 35,000 orders for the Model Y L on its first day of release.

Market backdrop

The timing of the Model Y L’s release comes as Tesla faces headwinds in China’s competitive SUV segment. Between January and July, Model Y retail sales in the country reached 202,257 units, a 17.15 percent decline compared to the same period last year, according to data cited by CNEVPost. It should be noted, however, that a good portion of this decline was due to the retooling of Tesla’s factories to make way for the new Model Y.

Despite the slowdown, the Model Y remains one of Tesla’s strongest performers globally. By introducing a higher-range, six-seat option, Tesla appears to be positioning the Model Y L as a way to boost demand and appeal to new buyers in a market that was previously only accessible to the much more expensive Model X.
