2015 Mercedes-Benz GLE SUV (W166) Dimensions, Size & Specs

The curb weight of the Mercedes-Benz GLE SUV (W166) ranges between 2000 and 2390 kilograms (approximately 4409 to 5269 pounds), depending on the specific trim and equipment. The maximum permissible weight of this SUV varies from 2850 to 3050 kilograms (6283 to 6724 pounds), accommodating passengers, cargo, and additional equipment. This weight range reflects the vehicle's robust build quality and safety features, balancing luxury with substantial structural integrity and performance capabilities.

The Mercedes-Benz GLE SUV (W166) offers a versatile luggage capacity to meet different needs. With the rear seats in use, the luggage space ranges from 480 to 690 liters (approximately 16.9 to 24.4 cubic feet), providing ample room for daily errands and family trips. When the rear seats are folded down, the capacity significantly increases to between 1800 and 2010 liters (63.6 to 70.9 cubic feet), allowing for the transport of larger items or bulkier cargo. This flexible cargo space makes the W166 GLE an excellent choice for those requiring both passenger comfort and substantial storage.

The Mercedes-Benz GLE W166 offers a ground clearance (ride height) between 180 and 202 millimeters (7.1 to 8.0 inches), depending on the suspension setup and optional features such as the Air Suspension package. This clearance provides a balanced approach for light off-road capabilities and comfortable road ride height, helping the SUV navigate rough terrain, dirt roads, and uneven surfaces without risking damage to the undercarriage. The adjustable suspension also enhances on-road handling, blending off-road readiness with everyday usability.

The Mercedes-Benz GLE W166 supports a variety of rim sizes, including 8.5J x 19, 9J x 20, 9J x 21, and others ranging from 17 to 21 inches. Tire sizes compatible with these rims include 255/50 R19, 265/45 R20, 265/40 R21, 235/65 R17, 255/55 R18, and 295/45 ZR21. These options allow owners to balance ride comfort, performance, and aesthetics. Larger rims with low-profile tires enhance sporty handling and styling, while smaller rims with taller tires improve comfort and durability, particularly useful for off-road or rough-road driving.

Generally, the Mercedes-Benz GLE W166 can fit into a standard garage; however, some aspects require attention. Its width ranges from 1926 to 1981 mm (75.8 to 78.0 inches) without mirrors, and 2141 mm (84.3 inches) with mirrors opened. Standard garages typically allow widths starting around 2400 mm (94.5 inches), so there should be enough lateral clearance, but opening doors comfortably might be tight depending on garage size. The height ranges between 1758 and 1796 mm (69.2 to 70.7 inches), which falls below the common garage door height of at least 2100 mm (82.7 inches). Overall, the SUV will fit inside most garages, but wide mirror spacing and door clearance need consideration.

Compared to its predecessor, the Mercedes-Benz M-Class (W164), the GLE W166 is slightly larger and more refined, reflecting Mercedes-Benz’s evolution in the midsize luxury SUV segment. The W166 GLE offers additional length, wider track, and improved overall dimensions, enhancing interior space and cargo capacity. The W164 M-Class had a length around 4770 mm (187.8 inches), making the W166 slightly longer by about 30 to 50 mm (1.2 to 2 inches). Visibility, ride height, and luggage capacity were also improved, contributing to a more premium and spacious driving experience while maintaining a similar footprint that is compatible with existing garages and parking spaces.

Within the midsize luxury SUV class, the Mercedes-Benz GLE W166 competes favorably with rivals such as the BMW X5 (F15), Audi Q7 (second generation), and Porsche Cayenne of the same era. The GLE emphasizes a blend of comfort, advanced technology, and strong safety features. Dimension-wise, it is comparable in length and width to these competitors, offering a competitive cargo capacity and cabin space. Mercedes-Benz’s focus on a smooth ride, luxurious interiors, and advanced driver assistance technology often gives the W166 an edge in terms of comfort and refinement, while still providing capable performance and off-road ability for those who require versatility.

The roof load capacity of the Mercedes-Benz GLE W166 is specified at 100 kilograms (approximately 220 pounds). This capacity is sufficient for most standard roof racks, cargo boxes, bike racks, or roof baskets, allowing owners to expand the vehicle’s cargo capabilities for outdoor activities or additional storage needs. It’s important to distribute the load evenly and adhere strictly to this limit to maintain vehicle stability, safety, and to avoid any structural damage. The SUV’s roof design supports securing various accessories securely, making it practical for families and adventure enthusiasts alike.

The Mercedes-Benz GLE W166 delivers a refined ride quality that balances comfort and control impressively. Thanks to optional Airmatic air suspension and advanced chassis tuning, the SUV absorbs road imperfections smoothly, offering a plush cabin experience on highways and urban roads alike. Handling is responsive and confident, aided by electronic aids such as dynamic select driving modes and optional four-wheel drive systems, which enhance traction and performance across diverse conditions. Whether navigating tight city streets or open country roads, the GLE W166 provides a composed and engaging driving experience that is typical of Mercedes-Benz’s luxury standards.
