It might be abnormal noises coming from the car's chassis. You need to check whether the screws inside the chassis have become loose or whether the tire shock absorbers make abnormal noises when bumping. More extended information is as follows: 1. Overview: The curb weight of a car, also known as the 'empty weight'. The curb weight of a car refers to the weight of the car when it is fully equipped according to the factory's technical conditions (such as spare tires, tools, etc., all installed) and all fluids are filled. The curb weight of a car is an important design indicator. 2. Others: The curb weight of a car is an important parameter affecting the car's fuel consumption. The fuel consumption of a vehicle is directly proportional to its curb weight, meaning that the heavier the curb weight of a car, the more fuel it consumes.
