Is it okay to load 600 pounds in a sedan trunk?

Basically, as long as the vehicle itself has no issues, it can handle this weight, but it will have an impact on the vehicle. For example, excessive weight can damage the shock absorbers, making them prone to problems. Loading too much weight and driving on rough roads can cause excessive body torsion, which over time may lead to a loose chassis and increased body noise. Here is some additional information: 1. Trunk cargo capacity: The cargo capacity of a sedan trunk is the lowest among all vehicle types, especially for three-box sedans. The trunk is located behind the rear wheels and at a considerable distance, so loading cargo increases the load on the rear axle and chassis due to the lever effect. Hatchbacks, SUVs, and minivans perform relatively better in this regard. 2. Solutions: If you really have no choice but to carry cargo, try to place heavy items on the rear seats or the passenger seat to balance the overall vehicle load and avoid excessive stress concentration. This can help minimize the impact on driving stability. When placing heavy items in the trunk, try to position them as far forward as possible and place lighter items toward the rear. This is beneficial for both the vehicle and safety, as excessive weight at the tail can significantly affect stability when driving.
I once tried filling the trunk with heavy items, loading several hundred kilograms, and the car felt extremely unstable when driving, as if the suspension was about to give out. Later, at the repair shop, the mechanic said it was due to overloading causing the suspension springs to deform, and the repair cost wasn't cheap. Generally, a sedan's load limit is specified in the manual—mine was around 300 kg. Carrying 600 jin (equivalent to 300 kg) likely exceeded that limit. Overloading not only increases fuel consumption but also accelerates tire wear and raises the risk of a blowout, especially on highways. I recommend checking your car's manual first to confirm the load capacity. If you really need to transport that much, it's better to do it in batches or use a larger vehicle—safety first.
To be honest, carrying 600 jin (300 kg) in the trunk is definitely not advisable. Sedans have limited designed load capacity, generally not exceeding 500 kg, and 600 jin equals 300 kg, which likely exceeds the limit. This can compress the rear suspension, making the vehicle unstable in terms of center of gravity, leading to potential loss of control during turns; tires may age prematurely, and braking distance could also increase, which is dangerous in emergencies. I've seen a friend do this, and halfway through the trip, the tire bulged, forcing them to call a tow truck, costing several thousand yuan. Safety is the top priority when driving—don't risk overloading. It's better to make multiple trips or rent an SUV.
