The width of the 2023 GLC SUV ranges between 1890 mm and 1920 mm (approximately 74.4 to 75.6 inches or 6.20 to 6.30 feet). When considering the opened side mirrors, the total width extends to 2075 mm, equivalent to about 81.7 inches or 6.81 feet. This dimension is important for parking and garage clearance, as the mirrors add significant width beyond the body itself.

The height of the 2023 GLC SUV spans from 1635 mm to 1648 mm, roughly equating to 64.4 to 64.9 inches or 5.37 to 5.41 feet. This height supports a commanding driving position typical of SUVs while maintaining a streamlined silhouette to balance aerodynamics and interior headroom.

The curb weight of the 2023 Mercedes-Benz GLC SUV varies between 1850 kg and 2340 kg, translating to approximately 4078 to 5157 pounds. This range depends on configuration, engine choices, and optional equipment. The robust curb weight reflects the SUV’s solid build quality, safety features, and luxury appointments.

The maximum weight, or gross vehicle weight rating (GVWR), for the 2023 GLC SUV is between 2510 kg and 2885 kg. This corresponds roughly to 5535 to 6361 pounds. The GVWR indicates the maximum safely loaded weight including passengers, cargo, and vehicle itself, ensuring structural integrity and vehicle control.

The luggage capacity of the 2023 GLC SUV ranges from 470 to 620 liters (approximately 16.6 to 21.9 cubic feet) with the rear seats upright, providing ample trunk space for daily use or weekend getaways. When the rear seats are folded down, cargo capacity expands significantly to between 1530 and 1680 liters, equating to around 54.0 to 59.3 cubic feet. This flexible storage makes it practical for larger items or extended trips.

A standard residential garage typically measures about 2.4 to 2.7 meters (8 to 9 feet) in width and roughly 5.0 to 6.0 meters (16.4 to 19.7 feet) in length. The 2023 GLC SUV, with a width ranging from 1.89 to 1.92 meters (6.20 to 6.30 feet) excluding mirrors and length between 4.716 to 4.749 meters (15.48 to 15.58 feet), generally fits comfortably inside a standard garage. However, the mirrors, which increase the width to 2.075 meters (6.81 feet), require caution when opening doors or parking near walls. Height at around 1.64 meters (5.38 feet) does not pose any typical garage clearance issues.

Compared to its predecessor (the X253 generation), the 2023 GLC SUV (X254) is slightly larger in several key dimensions. The length has increased marginally from approximately 4656 mm (183.2 inches) to up to 4749 mm (187.0 inches), giving it a bit more space inside and enhancing cargo capacity. Width has also expanded from around 1890 mm (74.4 inches) to a maximum of 1920 mm (75.6 inches), contributing to a more substantial road presence and improved interior shoulder room. Height remains similar but the new generation features subtle increases in ground clearance and overall stance, supporting better off-road capability and ride comfort. These dimensional increases reflect a trend toward greater interior space and versatility to meet evolving customer expectations.

In comparison with competing luxury compact SUVs like the BMW X3, Audi Q5, and Volvo XC60, the 2023 Mercedes-Benz GLC SUV holds its own with competitive dimensions and cargo versatility. Its length of up to 4749 mm (187 inches) is marginally longer than the BMW X3 (about 4708 mm or 185.3 inches) and Audi Q5 (4663 mm or 183.5 inches), giving the GLC a slight edge in interior space. The GLC's width (up to 1920 mm or 75.6 inches) also generally matches or slightly exceeds its rivals. Cargo capacity with rear seats up (470-620 liters or 16.6-21.9 cubic feet) is competitive and expands generously to 1530-1680 liters (54.0-59.3 cubic feet) with seats folded, placing it among the leaders in the segment for practical storage. This makes the GLC a strong contender for buyers prioritizing luxury, space, and versatility.
