What are the differences between the BMW X4 and X6?
4 Answers
The differences between the BMW X4 and X6 are as follows: 1. BMW X4: Length 4683mm, width 1890mm, height 1636mm. BMW X6: Length 4929mm, width 1989mm, height 1709mm. 2. The X6 is equipped with a 2.0T or 3.0T-V6 engine, paired with the same 8AT transmission. The X4 is equipped with a 2.0T engine paired with an 8AT transmission. The BMW X6 and X4 are derived crossover models of the X5 and X3 SUVs, respectively. Their lower body height and fastback tailgate design help reduce the drag coefficient, improving the vehicle's power performance and driving stability. 3. The BMW X6 does not adopt BMW's latest family design, so there are differences in the headlight styling between the two models.
I recently work at a 4S dealership and often help customers compare the X4 and X6. The most obvious difference lies in their dimensions—the X6, over 4.9 meters long, is like a big brute, while the X4, at just 4.7 meters, is more agile and easier to park. The rear seating in the X6 is more spacious, with adults having about two fists' distance between their knees and the front seats, whereas the X4's sloping roofline slightly compromises headroom. The X6's trunk can fit three large suitcases, while the X4 struggles with just two. Price-wise, the X6 starts at over 700,000 RMB, about 100,000 more than the X4, but it comes standard with 21-inch wheels for a more commanding presence. On the road, the X4 feels nimble and better suited for city driving, while the X6 offers greater stability at high speeds, making it ideal for long-distance trips.
As a father of two, practicality is my top priority when choosing a car. The X6 is clearly more hassle-free for taking kids out—it can fit two child safety seats in the back with room for an adult, while the X4's rear seat width is just barely enough. When loading a stroller into the trunk, the X6 can take it upright straight in, whereas the X4 requires folding the stroller twice due to the sloping roofline. For storage details, the X6's door panel can hold five water bottles, compared to just three in the X4. On family road trips, the X6's 75-liter fuel tank is 10 liters larger than the X4's, meaning fewer gas stops on long drives. However, for city commuting, the X4 does have slightly better fuel efficiency, saving about 1 liter per 100 kilometers.
Having played with cars for over a decade, let me talk about handling differences. With the same 30i engine, the X4 is 200kg lighter and corners like it's glued to the ground. The X6 has less body roll in turns but heavier steering. Brake pedal feel is more linear in the X4, while the X6 is softer initially. In terms of chassis tuning, the X4 in sport mode offers clear road feedback - you'll feel every manhole cover. The X6's air suspension excels at filtering out minor vibrations. For drifting, the X4's rear wheels break traction more easily, while the X6's electronic stability system intervenes quicker. Regarding modification potential, the X4 has more widebody kit options, while the X6 suits high-performance brake disc upgrades. I recommend test driving both on mountain roads to truly feel the differences.
