2025 BMW X3 Long (G48) Dimensions, Size & Specs

The curb weight of the BMW X3 Long (G48) ranges from 1885 kg to 1915 kg (4158 to 4221 lbs), which places it slightly heavier than some compact SUVs due to its extended size and premium features. Its maximum allowable weight is between 2450 kg and 2460 kg (5401 to 5423 lbs). This weight spectrum reflects robust construction, premium materials, and additional equipment, contributing to a stable and comfortable ride. When compared to other midsize luxury SUVs, the X3 Long maintains competitiveness, balancing weight and performance.

The BMW X3 Long (G48) features a ride height or ground clearance of 214 mm (8.4 inches). This relatively generous clearance for a luxury SUV helps the vehicle handle rougher terrains and uneven surfaces comfortably. It enhances off-road capability while maintaining good stability on paved roads. This clearance ensures that owners can confidently navigate countryside paths or snowy conditions while benefiting from the vehicle's sporty driving dynamics.

The BMW X3 Long (G48) offers a range of rim sizes including 19, 20, and 21 inches which can be fitted with tires such as 245/50 R19, 285/40 R20, 285/35 R21, 255/45 R20, and 255/40 R21. Larger rim and tire configurations generally provide better grip and sportier handling due to a larger contact patch with the road, but they can slightly reduce ride comfort and fuel efficiency. Smaller rims and taller tires typically offer improved comfort and a softer ride, making the suspension more forgiving over rough surfaces. This variety allows buyers to select a setup that suits their driving preferences, from sporty performance to comfort-oriented cruising.

With a length of 4865 mm (191.5 inches), width of 1920 mm (75.6 inches), and height of 1664 mm (65.5 inches), the BMW X3 Long (G48) generally fits into standard residential garages, which typically accommodate vehicles up to about 6 meters (19.7 feet) long. The width including side mirrors might require a garage wider than 2.5 meters (8.2 feet) for comfortable entry and exit. Homeowners should measure their garage dimensions, including clearance height and door width, to ensure a hassle-free fit, but in most cases, the X3 Long should fit comfortably within standard garage spaces.

The BMW X3 Long (G48) is an extended version of the current X3 model, designed specifically to offer more rear legroom and cargo space. Compared to the standard G01 X3, this version is longer—measuring 4865 mm (191.5 inches) in length versus approximately 4708 mm (185.3 inches) for the standard version—providing nearly 157 mm (6.2 inches) of extra length primarily benefiting passenger comfort and luggage capacity. Width and height remain fairly consistent to maintain the model's signature proportions. This increase makes the X3 Long a more family-friendly SUV without significantly impacting driving dynamics or urban maneuverability.

The elongated chassis of the BMW X3 Long (G48) significantly improves rear passenger legroom and cargo volume compared to the previous X3 generation, making it ideal for families or those who regularly carry rear-seat passengers. The additional length, around 157 mm longer than its predecessor, translates into more spacious seating and easier access to the rear seats. Despite the increased size, BMW manages to maintain an upscale interior with premium materials and generous features. This generation also benefits from advanced infotainment and driver assistance technologies, contributing to an overall more comfortable and refined driving experience.

Its width of 1920 mm (75.6 inches) is comparable with its competitors, ensuring a balanced presence on the road.

This combination of size and practicality positions the X3 Long as a strong competitor for buyers prioritizing space without losing the sporty handling expected from a BMW.

The BMW X3 Long (G48) has a maximum weight (gross vehicle weight rating) between 2450 kg and 2460 kg (5401 to 5423 lbs), which accounts for the vehicle's curb weight plus passengers, cargo, and optional equipment. This rating is essential for safety and performance considerations, indicating the maximum load the vehicle can handle without compromising structural integrity or handling. Staying within this limit preserves braking efficiency, suspension function, and tire safety. It also gives buyers an idea of the practical carrying capacity, factoring in passengers and luggage for trips, making the X3 Long suitable for both daily use and longer journeys.
