2009 Mercedes-Benz M-class (W164, facelift 2008) Dimensions, Size & Specs

With mirrors opened, the width of the W164 facelift M-Class ranges from 2124 mm to 2170 mm (83.6 to 85.4 inches). This wider stance is important to consider for parking or maneuvering in tight spaces, as the mirrors add significant width compared to the body alone.

The curb weight of the 2009 Mercedes-Benz M-Class W164 facelift ranges between 2060 kg to 2240 kg (4542 to 4938 lbs), varying by engine and equipment. Its maximum weight, which includes passengers and cargo, ranges from 2830 kg to 2950 kg (6240 to 6503 lbs), reflecting its robust SUV build designed for utility and comfort.

This generation delivers a generous luggage space of 833 liters (about 29.4 cubic feet) with the rear seats upright. When folding the rear seats down, the cargo capacity expands significantly to 2050 liters (approximately 72.4 cubic feet), providing ample space for large items and making it practical for travel and transporting bulky cargo.

The ground clearance ranges between 153 mm and 210 mm (6.0 to 8.3 inches), depending on suspension setup and driving modes. This ride height offers a good balance between on-road comfort and off-road capability, allowing the vehicle to handle rough terrain and obstacles while maintaining stable handling and a comfortable ride on pavements.

Standard residential garages typically measure about 2.4 m (8 feet) wide by 4.8 m (16 feet) deep. While the 2009 M-Class length (4.78 to 4.81 meters / 188 to 189 inches) fits within the depth comfortably, its width with mirrors open (2.12 to 2.17 meters / 83.6 to 85.4 inches) might be tight in narrower garages. The SUV usually fits, but care is needed when parking, especially in garages without extra clearance.

The 2009 facelifted W164 M-Class maintained a similar footprint to the pre-facelift W164 generation, with minor tweaks. The length remained close (around 4781 mm to 4812 mm), width stayed about 1911 mm without mirrors, and height varied slightly due to suspension tweaks. The facelift mostly updated the exterior styling, tech, and features, rather than major dimensional changes.

The 2009 M-Class W164 facelift is competitively sized among mid-size luxury SUVs of its time, comparable to the BMW X5 E70 and Audi Q7. Its length of around 4.8 meters (roughly 189 inches) places it squarely in the mid-size SUV category. Width and height are also similar, though the M-Class tends to offer slightly more luggage space with seats folded compared to some rivals, enhancing practicality.

The M-Class facelift offers a wide range of wheel sizes to suit different preferences and performance needs. Rim sizes include options from 17 inches up to 21 inches, specifically 7.5J x 17, 8J x 18, 8J x 19, 9.5J x 19, 8.5J x 19, 9J x 20, 8.5J x 21, and 10J x 21. Tire sizes range from 235/65 R17 to 295/35 R21, allowing owners to balance ride comfort, handling, and aesthetics.

The 2009 W164 facelift brought refreshed front and rear styling, updated technology including improved infotainment and safety features, and refined engine options to enhance performance and efficiency. Known for its strong build quality, luxurious interior, and capable off-road and on-road dynamics, the facelifted M-Class remained a popular luxury SUV choice in its segment during its production from 2008 to 2011.
