As a popular new energy vehicle at present, BYD Tang DM-i has very solid materials, including low NVH investment. For example, soundproof cotton is stuck in the inner container of the wheel cover, which can reduce the noise of gravel knocking, and the front and rear bumpers are also filled with a lot of soundproof cotton, which optimizes the sound insulation and vibration of the whole vehicle. I started BYD Tang DM-i 1 12KM distinguished model for more than half a year. Generally speaking, I feel that its NVH performance is quite excellent, and it is very good for environmental sound insulation and road noise suppression. Wind noise can be directly ignored when driving at medium and low speeds, and it will be a little bit after the speed is fast, but it will not be heard if you don't pay attention. The engine also performs well during daily driving, with no obvious noise, and the overall vibration suppression is also in place. Some riders call it "NVH library-level quiet space", and I think this metaphor is really worthy of the name.
