Practical review of articulation construction that improves the quietness of the featured Tesla Model Y.
Tesla's "Model Y", which is said to be the world's best-selling EV car, has finally landed in Japan. How did Model Y change by implementing the topical "acoustic construction" on Tesla's latest model? To say the conclusion first, it became a higher-grade ride comfort. Eh, isn't "articulation construction" a construction to reduce road noise?
Transfer From Model 3 To Model Y. Where Is The Difference?
This time, Model Y was introduced as a demo car in-house, and the "articulation work" was carried out at Focal' s plug & play store Chiba Kita in Chiba Prefecture. Immediately, I went to the shop and asked about the details of the tuning work on Model Y and the actual effect. Since the shop previously owned the "Model 3" as a demo car, it is also a shop where you can see the difference and the evolution of Tesla's car making from both the user's point of view and the professional point of view.
I feel that each Tesla model car making continues to evolve year by year. In many cases, we take feedback from the market in a short period of time, feed it back into the car making process, and upgrade it, instead of using model changes as the timing for evolution, as is the case with ordinary cars. One of the evolutions is improved quietness. We have also confirmed that the current model is quieter than the initial model for Model 3.”
Mr. Koshino Model 3 from Focal Plug & Play Store Chiba Kita told us so. Mr. Koshino himself seemed to be very interested in how it would be effective in the construction of Model Y, as the shop has a lot of achievements in sound tuning construction for Model 3. "When the Model Y was delivered, I checked each part and found that the double glass that was used in the front side windows in Model 3 was also used in the rear of Model Y. Also, the luggage floor panel surface The is reinforced with ribs, and the floor panel is made of strong resin, so you can see how quiet it is. The ADVANS sound articulation sheet was introduced by the company.
This time, we used the ADVANS sound articulation sheet made by BEWITH, which was newly developed exclusively for sound articulation construction. Based on a sound absorbing layer (nitrile rubber foam), a sound insulating layer (aluminum) with high sound insulation and a vibration damping layer (butyl rubber) with a strong adhesive specification that suppresses unnecessary vibrations. The three-layer structure sheet has a high noise reduction effect. It is a component that can be expected. I used "AD-8CS" with a thickness of 9 mm. The front is the inner cover, and the rear is the style of pasting the advanced sound adjustment sheet to the body side inside the fender.
Is There An Effect On Model Y, Which Is Originally Quiet?
After the construction was completed, I decided to ask Mr. Koshino, the owner, to talk about the differences in his feelings before and after construction.
Originally, it was quiet and pure due to the effect of the double glazing, but after the installation, I got the impression that small noises, especially high-frequency noises, were suppressed. The biggest difference is that the noise received from bumps on the road has been overwhelmingly suppressed, and the comfort has improved considerably. However, if you sit in the rear seat, there is no tonne cover, so noise from the luggage direction is a concern. I felt that the tuning work around the floor of the luggage seems to be effective for this car. This is an issue of MODEL Y for the future.”
Model Y is said to have a fairly stiff ride, partly because of the high rigidity of the "Giga Press" die-cast underbody (many readers have seen and heard of it, as it is often talked about in various test drive impressions of Model Y). deaf). When you actually ride it, you will be worried about the "push-up sound" due to its high rigidity.
However, that push up sounds are managed properly. If you implement sound tuning construction, you can enjoy the feeling of replacing the suspension with a one-grade high-quality one, probably because it has the effect of suppressing noise and micro-vibration from the suspension. Of course, I didn't physically replace the suspension, so the change in the sense of hearing affects the driving feeling, and that's how it feels.
Before the tuning work, the sound of the joints of the road was "thumping, thumping", but after the construction, it felt like a high-quality ride. Even though the suspension has not been changed, the feeling of pushing up has been reduced and the ride has become more comfortable.
