The Xiaomi SU7 is undeniably popular, with every aspect of its production generating buzz and topping the trending lists on major platforms. Recently, the Xiaomi SU7 disassembly phase has become the center of attention.
Today, leveraging the insights from popular online influencers, let's examine the original car sound insulation of the Xiaomi SU7. Is it bare to the core, just a formality, or does it leave no room for further car soundproofing modifications?
First, let's look at the doors of the Xiaomi SU7. According to the disassembly bloggers, the interior of the SU7's front doors is not the usual bare sheet metal but is mostly covered with steel plates. These plates are sealed with a layer of foam, which is more solid than the thin plastic films commonly seen.
The rear doors of the SU7 are also commendable, using hard fiberglass plastic boards for sealing, which appear even more robust than the front doors.
Examining the backside of the interior door panels of the SU7. there is a layer of white cotton. This cotton is notably thick, unlike the superficial thickness seen in some cars, and visibly more substantial, surpassing many Japanese cars in quality.
Regarding the door soundproofing structure of the SU7. it can be said to significantly outperform some bare-bones models. From a car owner's perspective, this enhances driving and riding comfort, showing genuine sincerity.
Next, let's review the floor as disassembled by bloggers. The SU7's floor is covered with a relatively thick foam material, which is lightweight and waterproof, likely reducing noise from the chassis to some extent.
Upon removing the area around the foot pedals, one might mistakenly think it's the notorious "black heart cotton," which is prone to dampness, mold, and odor. However, it's not. The SU7 uses polyester fiber cotton in this area, which is a type of cotton formed from melted plastic filaments, waterproof and mold-resistant.
The thick foam material and polyester fiber cotton used in the SU7's interior floor structure for soundproofing are far superior to the bare sheet metal or the "black heart cotton" and asphalt damping boards seen in some other models, making a striking and overwhelming difference.
As a pure electric vehicle, the SU7 doesn't have engine noise, but motor noise is unavoidable. How does the SU7 address this? Let's check out another disassembly blogger who examined the SU7's external chassis.
From their disassembly and introduction, it's evident that the front motor of the SU7 is wrapped in a layer of sound-absorbing cotton. From a purely sound insulation perspective, this layer of cotton is likely used to reduce motor noise, preventing excessive noise from entering the cabin.
As for whether the sound-absorbing cotton added to the motor serves this actual purpose or intention, we won't delve too deeply.
With soundproofing materials used in the front doors, internal floors, foot pedal areas, and motor sections, the SU7's approach is quite impressive. After getting accustomed to other models' "bare" interiors, seeing the "thick" treatment of the SU7 naturally leaves a favorable impression.
Considering the known disassembled areas and adding the comfort or silent tires of the SU7. its driving comfort level should not be bad at all, at least it looks promising. As for the actual experience, friends who have already driven the SU7 can share their insights.
After three years of development, upon thorough disassembly, it's clear that some once top-tier, popular models are just exploiting their brand reputation, leaving consumers with bare interiors or subpar materials like asphalt damping boards and "black heart cotton." Where's the conscience in that?
After understanding the Xiaomi SU7's original car sound insulation from the disassembly bloggers, let's discuss whether there's a need for further soundproofing upgrades on the Xiaomi SU7.
The necessity of upgrades depends on the car owner's comfort requirements and whether the sound insulation solutions provided by professional car audio shops align with the Xiaomi SU7.
However, when a Xiaomi SU7 comes to a shop requesting soundproofing upgrades, reputable car sound insulation brands (such as Shurnoff Car Sound Insulation) and professional audio modification shops across the country can undoubtedly provide satisfactory solutions.
Lastly, some may still argue that post-purchase soundproofing upgrades are useless, calling them a "scam." But if soundproofing were useless, why would the Xiaomi SU7 put so much effort into the soundproofing cotton in various parts?
