As a car owner, I've been driving the 2021 BMW X3 for almost two years, and the trunk space is truly sufficient. The official standard capacity is 550 liters, with dimensions of approximately 100 cm in length, 100 cm in width, and 70 cm in height. For every family trip, fitting three large suitcases plus backpacks is more than enough. The rear seats can be folded down, expanding the volume to a whopping 1,600 liters, making it easy to load a bicycle or camping tent. The design is very user-friendly, with a large opening for easy loading and unloading, and a hidden storage compartment under the floor. Compared to the previous generation X3, the 2021 model has better space optimization, with actual loading capacity exceeding expectations, making it particularly suitable for city commuting and weekend trips. Remember to check the sealing strips during maintenance to avoid water leakage affecting items during rainy days. Overall, the space utilization is perfect, offering strong practicality and peace of mind.
