The vehicle's manual provides the curb weight and gross vehicle weight. Subtracting these two figures and then deducting 400kg gives the maximum capacity for the trunk. Below are the hazards of trunk overload: 1. Increased vehicle weight compresses the springs, keeping them in a prolonged compressed state, and places additional strain on the engine. This can easily damage the vehicle's frame and rear axle suspension, reducing the engine's lifespan. 2. The vehicle may experience reduced acceleration power. 3. Fuel consumption increases. For every 10% increase in weight, the car consumes 6% more fuel. 4. The overall driving and handling performance of the car is diminished, significantly raising the risk of losing control during uphill and downhill driving.

I once accidentally overloaded my car and caused problems, so I pay close attention to this: The typical load capacity of a sedan's trunk usually shouldn't exceed 300 to 400 kg, depending on your vehicle's manual. For example, my old family sedan had a designed limit of 320 kg. Overloading can prematurely wear out the suspension system, cause uneven tire wear, and in extreme cases, affect the car's balance, increasing the risk of skidding when turning. I know a friend who forced 500 kg into their car for moving, resulting in deformed suspension and over 2000 yuan in repair costs. Safety first—always estimate the load before packing, and don't gamble with luck. For a new car, check the manual or ask the dealer for the standard. Overall, controlling the weight is key to avoiding traffic accidents.

I often go on self-driving trips, and stuffing the trunk is a common occurrence. My car's trunk has a load capacity of about 300 kg. I once tried exceeding the limit with luggage, and the car drove unsteadily—it was too dangerous. I remember packing too much camping gear for a family trip, estimated to weigh over 350 kg, which slowed down the braking response and increased fuel consumption. Different sedans vary greatly: compact cars like economy models can only handle around 250 kg, while midsize cars can manage slightly higher, up to 350 kg. It's recommended to use a household scale to weigh heavy items in actual use to ensure you don't exceed the limit. An overloaded trunk also affects handling stability, so control weight distribution during long-distance driving. Develop the habit of reducing extra burdens to ensure a worry-free journey.

From a mechanical perspective, the trunk typically has a load capacity of around 300 kilograms. Exceeding this weight limit can compress the suspension springs and, over time, lead to damage to the shock absorbers. Based on my experience, it's advisable to avoid concentrated stacking of items; distributing the weight evenly can help mitigate risks. Overloading also affects steering precision and increases braking distance. Always refer to the vehicle's manual for specific load limits.
