Curb weight refers to the quality of the car fully equipped (but excluding cargo, driver and passengers), which includes not only the engine, chassis and body, but also the weight of the car after being filled with fuel, lubricating oil, coolant and carrying the tools on board.
The curb weight of a car has a great impact on the performance of the car. If the curb weight is large, the advantage is that it feels stable to drive, and it is not easy to float when driving at high speeds; The negative effects are high fuel consumption due to high power consumption, which is easy to affect the performance of air conditioning, slow starting speed, and long braking distance.
Curb weight is very important for a car because it is one of the important indicators of car performance. If the curb weight is too large, the car will become too bulky, which is not only easy to flutter in city driving, but also increases safety hazards at high speeds.
In addition, the large curb weight will also lead to an increase in vehicle power consumption, high fuel consumption, affecting air conditioning performance, slow starting speed, long braking distance and other problems.
However, an overly light curb weight is also not a good thing. This will cause the vehicle to flutter easily during driving, making it difficult to ensure stability and safety. In addition, light vehicles will also be greatly affected in terms of power performance and handling performance, which is not conducive to the performance of the vehicle in actual use.
Therefore, for a car, its mass (in this case, not its reliability and workmanship, etc., but its "weight") should be a reasonable value, not too light, not too heavy. Light vehicles have advantages in terms of energy saving, environmental protection, and carbon emission reduction, but it is necessary to pay attention to avoid safety hazards and handling problems caused by being too light. For heavy-duty vehicles, care needs to be taken to avoid the economical fuel consumption and high maintenance costs caused by being too heavy.
In short, curb weight is a process of weighing the pros and cons for a car, and it needs to be reasonably selected according to the actual use needs and performance requirements of the vehicle.
