2009 BMW X6 M (E71) Dimensions, Size & Specs

The height of the BMW X6 M (E71) stands at 1684 mm (66.3 inches). This relatively tall stature compared to conventional sedans provides excellent road visibility for the driver, enhancing safety and confidence when driving in traffic. The increased height also contributes to a spacious and airy interior cabin, improving passenger comfort especially for those sitting in the rear. Additionally, the height supports an elevated driving position typical of SUVs, which many drivers prefer for better control and view.

The BMW X6 M (E71) has a curb weight of 2305 kg (5085 lbs) and a maximum permissible weight of 2905 kg (6406 lbs). The curb weight reflects the car's empty weight including all standard equipment, fluids, and a full tank of fuel but without occupants or cargo. The relatively heavy weight is due to its robust SUV architecture and M-specific performance parts. This weight contributes to its solid road feel and stability at high speeds but can also lead to increased fuel consumption compared to lighter vehicles. The maximum weight indicates the upper limit with passengers and cargo; respecting this limit is important to maintain safety and performance.

The BMW X6 M (E71) provides 570 liters (20.1 cubic feet) of luggage capacity with the rear seats upright, which is ample for daily use, family trips, or shopping errands. When the rear seats are folded down, the cargo space expands significantly to 1450 liters (51.2 cubic feet), greatly increasing versatility for carrying larger items such as sports equipment, furniture, or luggage for extended travel. This folding option enhances the SUV's utility, allowing it to shift from a passenger-focused vehicle to a practical cargo hauler with ease.

Given the BMW X6 M's length of 4876 mm (191.9 inches) and width of 2195 mm (86.4 inches) with mirrors open, fitting it into a standard residential garage can be tight but generally feasible. Many standard garages are about 2400 mm (8 feet) wide and 4800-5000 mm (16-16.5 feet) long. While length is suitable for many garages, the width with mirrors deployed requires careful maneuvering to avoid damage to mirrors or adjacent walls. It is advisable to fold in the mirrors where possible or consider a garage slightly wider than average for easier access.

Compared to the preceding BMW X5 M (E70), the BMW X6 M (E71) shares many mechanical components but has a distinct coupe-like SUV design. Dimensionally, the X6 M is longer at 4876 mm versus roughly 4855 mm for the X5 M, and the width is similar, though the X6 M's roofline slopes more dramatically which reduces rear headroom slightly. The height of the X6 M is somewhat lower than the X5 M, reflecting its sportier styling. These dimensional nuances make the X6 M feel sleeker and more aggressive, while the X5 M retains a more traditional SUV shape with somewhat better interior space in the rear.

When compared to contemporaries like the Porsche Cayenne Turbo and Mercedes-Benz ML63 AMG, the BMW X6 M (E71) is broadly similar in width and height. The X6 M's width at 1983 mm (78.1 inches) without mirrors aligns closely with these rivals, although some competitors may have slightly lower overall heights. The X6 M’s coupe-like sloping roof sets it apart by reducing height compared to more traditional box-shaped SUVs. Overall, the X6 M offers competitive exterior dimensions that balance aggressive styling and practical interior space, positioning it well within the high-performance luxury SUV segment of its era.

The BMW X6 M (E71) comes equipped with front rims sized at 11J x 20 inches and rear rims at 10J x 20 inches, fitted with 315/35 R20 tires at the front and 275/40 R20 tires at the rear. These wide performance tires contribute significantly to the car’s superior grip, cornering capability, and handling dynamics typical of BMW M models. The staggered tire setup enhances traction and stability, especially when accelerating and cornering at high speeds. However, this setup also results in a firmer ride quality typical of sports-tuned SUVs, which prioritizes performance over plushness.

The BMW X6 M (E71) is the high-performance variant of the X6 lineup, engineered by BMW's M division to deliver superior power and handling. It features a tuned 4.4-liter twin-turbo V8 engine producing about 555 horsepower, significantly more than standard X6 engines. Performance upgrades include sport-tuned suspension, enhanced brakes, M-specific all-wheel drive, and aggressive aerodynamic elements. The interior is equally upgraded with M-specific trim and sport seats. These features combine to make the X6 M a blend of luxury and sports car agility, offering a unique driving experience within the SUV segment.

The BMW X6 M (E71) balances high-performance capability with practical aspects suitable for everyday use. Its relatively large luggage capacity of 570 liters (20.1 cubic feet) expandable to 1450 liters (51.2 cubic feet) with rear seats folded makes it capable of handling family and recreational cargo demands. The spacious interior and elevated driving position offer comfort and visibility for daily driving. However, its substantial curb weight and performance tuning mean fuel consumption and ride comfort may not be as optimized as standard SUVs, making it more suited for drivers who prioritize sporty dynamics and luxury alongside practicality. Additionally, maneuvering in tight urban environments may require care due to its large size.
