Xiaomi New Generation SU7 Door & Window Sound Insulation Effect Review

How is the sound insulation performance of the doors and windows on the new‑generation SU7?

The entire lineup of the new‑generation SU7 comes standard with four‑door silent laminated glass. The PVB material in the glass enhances sound insulation, delivering a quieter cabin. Even at a highway speed of 120 km/h, passengers can converse without raising their voices intentionally.

The Max variant offers an optional ultra‑quiet cabin upgrade, featuring super‑silent PVB front windshield and additional acoustic materials. Compared with the previous‑generation SU7 MAX, the overall vehicle sound insulation is improved by an average of 3dB.

When you are in noisy environments, such as waiting at a red light next to a bus or driving past a construction site, closing the windows immediately creates a noticeable quiet atmosphere with strong sound isolation.
