It's definitely a commercial. Monro has a platform. Part of having a small business like his is sales. If this helps bring businesses to him, then great. He's letting people know he's open to work on their projects. This makes him feel uncomfortable, and I get it. But I like that it makes him feel uncomfortable. It should. That is a sign of old school integrity right there.

I've never understood why *the biggest enemy of a battery is cool not hot.* I've always thought while once used as motive power heat is what degrades efficiency of a battery and not an excessively *cool*(by temperature) battery. Having been a snowmobile rider in my past life I can speak with Authority on the value of *active cooling*(running a 2 stroke motor through snow) as creating an enormous benefit to engine efficiency in point of fact. And I think a *note* on energy efficiency is always worthy of discussing as the idea that a two stroke motor is *energy inefficient* relative to anything is plainly false. We use to drag race stock snowmobiles against tricked out motorcycles in Florida and blow them away all the time way back in the 1990s before everyone caught on to the obviousness as to why that was.

[@zackj997]

@@doolittlegeorgeI think he may have been referring to the cool as the biggest enemy in the context of efficiency as turning on the heater can draw almost 8kw on the Model 3.

[@Poxenium]

@@doolittlegeorge The optimal temperature for most Li-Ion batteries is around 35C. Significantly higher temperatures may be dangerous, cells can get damaged. Anyone who knows chemistry, knows that most reactions slow down in lower temperatures, that's what happens to batteries too. A cold battery (approximately under 10C) loses some of the capacity AND is slowed down, meaning that it can't charge nor output energy as fast as at 35C. These problems will be solved with new battery formulas soon. PS: gas engines have nothing to do with efficiency. Most of them create more heat than rotation, except for those weird rotary engines from Mazda, which can reach 50% efficiency.

[@TennisGvy]

@@Findalfen Big flat areas like the other person said. Sandy called it "drumming" because those large areas really move like a drum head.

@@Findalfen take a screwdriver, knock the surfaces. If it rings, put some mastic on that area. If sound muffled no need to apply nothing.

[@HenryLoenwind]

@@bassrover5925 It takes a bit more, especially when talking mass production. One thing to keep in mind is that an even coating of that stuff is nearly useless. You then still have the exact same drum, it just takes a bit more energy to get it vibrating. Instead you want to capture the specific frequencies it resonates at and convert them into heat. You can see this nicely on the trunk where there are 2 triangles. Those cover a wide frequency spectrum, dampening the metal's vibrations at those frequencies.

I was surprised that there was no comparison of the Y's sound deadening relative to the Model 3? There have been some anecdotal reports of the Y being quieter. Did you see any evidence to support that?

[@luca7069]

Until someone gets in both cars with some proper instrumentation, who says "it's quieter" it's probably just down to placebo effect.

[@GoldenDon548]

I think the comparison should be taken with a grain of salt. The Model 3 Munro analysed was a pretty early production model. So all comparisons are a current Model Y with an old Model 3. Model 3 got a lot of tweaks and upgrades since then. So one should not say "Model Y has this and Model 3 doesnt" or "this is different between the Y and the 3" just based on these videos. We dont know if the parts are also changed on current Model 3. Still nice to see what changed in these years.

[@DavidHRyall]

One youtuber did a comparison with a decibel meter, it was very minor - like one or two points difference

[@kkallioj]

@jaysbrain 3dB is twice the sound energy, but not twice the subjective listening experience. To the ear it's barely noticeable.

[@quantaca5773]

@@DavidHRyall the downside of that decibel meter is that it only tells you about the loudest sound, it doesn't tell you anything about the sound in general, so whatever sound there is may be almost as loud but there's less different sounds to be heard. making it sound much quieter. also certain frequencies can be very annoying to (different) people as we're more sensitive to them. hope i'm making some sense here as its sometimes hard to put what i'm thinking into english

[@hunterbill77]

Dear Sandy - Greetings from the NHS secured UK. The original use of the acronym NVH was (at least in the UK) in about 1967 (a bit before your time I guess) with the release of the first Ford Cortina. NOISE - VIBRATION - HEAT. Please correct me if I am wrong.

[@SpenserRoger]

On my Mercedes SUV I took out the front plastic wheel well liners out and covered them in a layer of aluminum foil constraint layer, a layer of butyl rubber elastomeric layer, and another layer of metal constraint... Apparently doing it exactly like this creates a sound deadening layer that is as effective as an equal thickness of lead (which is incredibly dense). I also mounted the plastic on rubber insulators when I put them back on. It worked so well that I no longer could hear the wheel noise at all...not even above highway speeds with loud mud tires, or even spinning and shooting gravel. Btw my "metal constraint layers" were just aluminum foil tape, and my rubber is a membrane for sealing basement walls. It probably added a couple pounds. Now I've been in all sorts of vehicles, the over built w140s from the 90s (with like 6 inches of dense foam in the floors and double glazed windows in the doors) before MB got bought out by Chrysler and had many of the engineers replaced...new MB, Teslas, new f150s, Austin Martin's, lexus, BMW, Audi, etc... And not a single one has the nearly zero noise level that my amateur self did. I also went back and did the rear and now all I can hear is the exhaust. I also did my doors, but not so much to keep sound out but to keep it in and turn the doors into big speaker boxes to get more mid bass. It sounds amazing. Like nothing on the market. I really don't understand why manufacturers don't do more of this considering it's so simple and light and brings down loudly audible road and highway noise to utterly inaudible. I've heard of Audi putting a carpet like material inside the wheel wells to help dampen the frequencies, I was going to try that but like I said the road noise is completely totally gone. Like not there at 100 mph not there.

What Monro & Associates does have a quite good analogy in the software world. Source code gets compiled into machine code. Sure you can have the processor manual and look at what each instructions do and follow along but takes lots of time and you don't get the bigger picture. Then there are programs called decompilers that takes machine code you know was written in one language and tries to reconstruct the source code. It won't be 'nice' code always but more understandable. Sandy and the team do decompilation of products (machine code) into design and parts costs (source code). And also work with designs (source code) and optimize it - like when you use optimization flags for the compiler.
