Which Cars Do Not Use Asphalt Damping Sheets?
2 Answers
Cars that do not use asphalt damping sheets are Volvo models. Asphalt damping sheets refer to damping sheets made from asphalt as the raw material. As a viscoelastic material, they adhere closely to the steel panels of the car body to reduce noise and vibration. Volvo models include: Volvo S60, Volvo S90, Volvo XC60, Volvo XC40, Volvo V60, etc. Taking the 2021 Volvo XC40 Smart Fashion Edition as an example, it is a compact 5-door, 5-seat SUV with body dimensions of: length 4425mm, width 1863mm, height 1652mm, and a wheelbase of 2702mm.
In my recent research on automotive materials, I found that vehicles without asphalt damping sheets are mainly those brands that prioritize environmental protection and health, such as many electric vehicles and luxury models. Brands like Tesla use water-based damping sheets or special foam instead of traditional asphalt, as this reduces the release of toxic gases inside the car, making it safer especially during high summer temperatures. Some car owners prefer such vehicles because the interior has less odor and is less likely to cause allergies. Of course, this is not applicable to all vehicles, as some low-cost economy cars sometimes use cheaper asphalt to reduce costs. However, the trend is that more brands are shifting towards eco-friendly materials.
