Watch Munro Inspect Tesla Model Y Welds, ABS, Reinforcements and More


We love these Tesla Model Y disassembly videos that Sandy Munro makes. Fortunately for us, Munro posts at least one a day, and there are still a lot of vehicles to cover. In this latest video, Munro inspects the welds on the Model Y door sills, the self-piercing rivets (SPR), the tailgate reinforcement plate, the head impact countermeasures (HIC), the anti-lock braking (ABS) and eReinforcements in expanded polypropylene foam (EPP) in the ground.

When Munro disassembled the Model 3, one of the things he criticized was the welds on the door flange. However, the Model Y door flange welds were perfect in Munro’s opinion, and he even added that any automotive company, foreign or domestic, would be happy to have the quality of the Model Y welds.

“When I saw the Model 3, I really didn’t have a good opinion of the welds. I didn’t have a good opinion of how the welding was done, and I didn’t like the variety. – Sandy Munro on Tesla model 3 door flange welds

Next, Munro looked at the rear door flange where Tesla is to join the aluminum and steel. In doing so, Tesla used self-piercing rivets and Munro notes that he is pleased that Tesla has installed them all on the same side. It doesn’t actually say that Tesla hasn’t done this in the past, but judging how happy he was to see it that way, suggests that Tesla didn’t always do it the way it did on the Y model.

Munro then points out a small piece of foam that is attached to the inside of the plastic cover from the inside of the B-pillar. He notes that even though it is small, it is just enough to provide some cushioning if a passenger hits his head against the pillar from inside the vehicle and calls it a “nice touch”.

Munro then heads to the back of the vehicle and starts talking about what he calls a rear crush plate. He admits that he doesn’t know what to call him because he hasn’t seen anything like it on any other vehicle. The purpose of the plate is to minimize damage to the vehicle in a rear impact. He likes it and says it’s a good idea.

It was then that Munro said something that surprised us. He said he heard people say that the hatch may be too low and that it could be damaged in a collision. It was actually me he was referring to because I wrote the InsideEVs article last week that asked exactly that. We then followed it up with another post that showed a photo of a damaged Model Y hatch.

Munro said he didn’t think it was going to be a problem due to the rear compression plate and the fact that the Model Y tailgate seemed higher than that of a Chrysler minivan. My instinct is to trust Munro because he knows a lot more about the automotive design and engineering that I do. It is also encouraging to hear that Munro doesn’t seem at all to think this is a problem. However, we continue to ask him for clarification, so that he can explain his reasoning to us further. At the very least, we’re happy to find that Sandy is reading InsideEVs!

We then discover how Tesla used an expanded polypropylene reinforcement in the rear floor. Munro said he uses this material a lot in the defense projects he does, and to say that Tesla’s decision to use EPP where they did is a great idea, at a great price, without no sacrifice.

“There are so many different types of foam in this car that it’s amazing

Munro ended with a look at the ABS system. He points out that it looks like the same system used in the Model 3, but that Tesla changed the piping for an unknown reason. Munro speculates that Tesla may have found a problem with this one in Model 3 and fixed it for Model Y.

So watch the video and let us know what you think. We are very happy to see Munro continue to rave about the Y model and to point out that Tesla seems to have really improved its design and manufacturing techniques since the launch of the model 3. We will have the next shortly after Munro l ‘posted on his new YouTube channel Munro Live.
