Generally, the trunk size of a sedan varies depending on different situations, as follows: 1. Hatchback: The trunk volume is approximately 150 to 300 liters. 2. Sedan: Usually ranges from 350 to 500 liters. 3. SUV: Approximately 300 to 600 liters. However, when the rear seats are folded down, the trunk volume can increase to around 1300 to 1800 liters. 4. Rear Seat Folding: The specific situation depends on the model. Nowadays, many sedans or SUVs support the rear seat folding function, which effectively enhances the vehicle's loading capacity. If you have cargo transportation needs, you can choose a model with this feature.

The sedan in my family is usually used to pick up and drop off the kids at school. I've actually measured the trunk dimensions: the depth is about 95 cm, the width is around 100 cm, and the height is approximately 50 cm. It can generally fit two 28-inch checked suitcases upright along with some miscellaneous items. On weekends when I take the kids camping, I've managed to squeeze in two folding tents and three sleeping bags. However, for particularly long items like fishing rods, I have to place them diagonally or fold down the rear seats. I think when a car, don't just focus on the listed volume parameters—always open the trunk and test how your actual items will fit.

After comparing data from dozens of compact cars, I found that the trunk capacity of regular sedans typically ranges between 400-550 liters. For example, the Corolla has an interior trunk width of 105 cm and a depth of 98 cm, while the Lavida has a depth of approximately 102 cm. Hatchbacks like the Focus offer a larger trunk opening but with shallower depth. When actually loading items, it's important to note that the wheel arches may narrow the width, and in some models, the rear suspension may encroach on height space. I often advise friends to bring a 24-inch suitcase to test the fit at the dealership before purchasing, as there's always some discrepancy between official specifications and real-world usage.

Having driven a taxi for 15 years, I've gained deep experience in helping passengers with their luggage. The trunk of a standard sedan can usually fit three carry-on suitcases, but for 28-inch large suitcases, typically only two can be accommodated. The most challenging situations involve wheelchairs or strollers—those over 50 cm in height often require disassembling the wheels. Some well-designed models, like the older Teana, have very tidy trunk spaces, allowing 20% more storage compared to cars with odd protrusions. I always keep some elastic nets in the car to secure loose items.

Moving last time made me reconsider trunk dimensions. The depth of regular sedans is generally less than 1.1 meters. I specifically measured mainstream models at the auto show: Civic 98cm depth, Sagitar 104cm, and Camry 112cm. If you frequently transport large items, I recommend choosing models with 4/6 split-folding rear seats, which can extend the depth to nearly 2 meters when folded down. Due to layout, the trunk floor of new energy vehicles is usually higher. For example, the Model 3 has only 46cm height, making it a bit cramped for large luggage boxes.

In recent years, there have been innovations in sedan trunk designs. Traditional three-box sedans typically feature a depth range of 90-120 cm. Some brands have begun optimizing internal space utilization—for instance, Škoda's hatchback design achieves a 110 cm depth while maintaining an oversized opening. Car enthusiasts have tested and found that the 508's trunk offers more practical capacity than its specifications suggest, as designers reduced the spare tire well space. Some models now also come with adjustable lift-up floors, allowing flexible height adjustments to accommodate various loading needs.
