2 Answers
The black plastic under the door of the Wuling Hongguang S3 is called the door seal strip. The door seal strip is used to seal the door, making it harder to open, and serves functions such as shock absorption, waterproofing, noise insulation, heat insulation, dust prevention, and fixation. The Wuling Hongguang S3 is a mid-size SUV with body dimensions of 4655mm in length, 1735mm in width, and 1790mm in height, with a wheelbase of 2800mm and a fuel tank capacity of 49 liters. The Wuling Hongguang S3 is equipped with a 1.5T turbocharged engine, delivering a maximum power of 108kW at 5200 rpm and a maximum torque of 250Nm between 2200 to 3400 rpm.
I've been driving the Wuling Hongguang S3 for several years. The black plastic part under the door is called the sill trim, also known as the scuff plate in the industry. Its main function is to protect the car body from scratches. For example, when parking, if another car door hits it, it can act as a buffer. Small stones or debris from the road won't damage the metal part either. The material is usually engineering plastic, and the black design is both dirt-resistant and wear-resistant, making it less likely to show stains. A simple wipe with a wet cloth during car washing is enough. Located at the bottom of the door frame, it also helps prevent slipping and tripping when getting in and out of the car, making it quite practical. You can also add stickers or other decorations, but I recommend regularly checking for cracks. Keeping it in good condition can extend the overall lifespan of the car.
