2009 Mercedes-Benz GL (X164 facelift 2009) Dimensions, Size & Specs

The Mercedes-Benz GL (X164 facelift 2009) has a curb weight ranging from 2355 kg to 2475 kg (5193 to 5455 lbs) and a maximum weight between 3150 kg and 3250 kg (6945 to 7165 lbs). The substantial curb weight reflects the SUV's large size, luxury features, and robust build quality, contributing to a solid and stable ride. However, this heavier weight can slightly reduce agility compared to lighter SUVs and impacts fuel efficiency, generally leading to higher fuel consumption. The maximum weight rating allows for considerable payload, including passengers and cargo, without compromising safety or vehicle integrity.

The Mercedes-Benz GL (X164 facelift 2009) offers a generous luggage capacity of 620 liters (21.9 cubic feet) with the rear seats in their upright position, ideal for daily use such as grocery shopping or luggage for several passengers. When the rear seats are folded down, the capacity expands dramatically to 2300 liters (81.2 cubic feet), allowing for bulky items, large shopping trips, or moving gear. This high degree of versatility makes the GL suitable for families and outdoor enthusiasts who require flexible cargo space.

The Mercedes-Benz GL (X164 facelift 2009), with its length of 5099 mm (16 feet 8.4 inches), width of 1920 mm (6 feet 3.6 inches), and height of 1840 mm (6 feet 0.4 inches), is relatively large for SUV standards. Standard residential garages typically measure about 2.4 to 2.7 meters (8 to 9 feet) in width and 5.5 to 6 meters (18 to 20 feet) in length, so in terms of length and width, it will generally fit, but it may be a tight fit especially in narrower garages. The height is less of a concern unless the garage has a low ceiling or specialized features like storage racks overhead. Owners should measure their garage space carefully, especially accounting for door clearance and ease of entry/exit.

The Mercedes-Benz GL (X164 facelift 2009) has a ground clearance of 198 mm (7.8 inches). This elevated ride height is beneficial for tackling uneven terrain, light off-roading, and overcoming obstacles such as curbs or shallow stream crossings without damage to the underbody. While primarily designed as a luxury SUV, this ground clearance gives the GL respectable versatility in rough conditions. Additionally, the higher stance provides better driver visibility compared to lower vehicles, increasing confidence on and off the pavement.

The Mercedes-Benz GL (X164 facelift 2009) offers two rim sizes: 18 inches and 19 inches. Corresponding tire sizes are 265/60 R18 and 275/55 R19 respectively. The larger 19-inch rims typically improve handling by reducing sidewall flex and increasing road contact, though they may transmit more road imperfections, affecting ride comfort slightly. The 18-inch rims with a higher tire sidewall offer a more cushioned ride and better absorption of bumps, which is ideal for off-road conditions or rough urban surfaces. Both tire options balance performance and comfort well for a luxury SUV.

The Mercedes-Benz GL (X164 facelift 2009) retains the fundamental dimensions of its predecessor but features subtle enhancements. The original pre-facelift X164 measured roughly the same in length, width, and height. The facelift focused more on styling updates and mechanical improvements rather than significant size changes. The facelifted model typically offers refined aerodynamics and slightly updated interior packaging, which might marginally affect cargo capacity and weight. However, overall, drivers familiar with the first generation will notice very similar size and space characteristics in the facelifted GL.

During the 2009-2012 production of the Mercedes-Benz GL (X164 facelift), it competed against full-size luxury SUVs like the BMW X5, Audi Q7, and Lexus LX. The GL was generally larger in length and height compared to the BMW X5, which is more mid-size oriented, providing the GL with a more spacious cabin and cargo area. Compared with the Audi Q7, the GL had comparable length but was slightly wider and taller, aiding interior roominess and road presence. The Lexus LX, a traditional body-on-frame luxury SUV, often matched or exceeded the GL in off-road capability but was typically heavier and slightly longer. Overall, the GL balanced size, luxury, and versatility effectively in its segment.

The 2009 facelift of the Mercedes-Benz GL (X164) introduced several updates enhancing both aesthetics and function. Visually, it featured redesigned front and rear fascias including new LED daytime running lights and refreshed grille styling for a more modern look. Interior quality was improved with upgraded materials and infotainment technology, including better multimedia interfaces. Mechanically, the facelift introduced improved suspension tuning for better ride comfort and handling balance. Safety was enhanced with additional driver assistance systems like improved stability control and optional night vision. These updates helped the facelifted GL maintain competitiveness in the luxury SUV market while retaining its commanding presence and spacious design.
