The 2026 Mercedes-Benz GLC SUV offers a versatile luggage capacity of 570 liters (20.1 cubic feet) with the rear seats upright, which is sufficient for everyday needs such as groceries and luggage for trips. When the rear seats are folded down, the luggage space expands significantly to 1740 liters (61.4 cubic feet), allowing for the transportation of larger items such as sports equipment, furniture, or bulky cargo. This flexibility in cargo space makes the Mercedes-Benz GLC highly practical for families and outdoor enthusiasts who require variable space utilization.

With a width of 1913 mm (75.3 inches), the 2026 Mercedes-Benz GLC SUV should comfortably fit within the confines of a standard garage and most parking spaces, which typically measure about 2.4 to 2.7 meters (94.5 to 106 inches) wide. However, drivers should account for side mirrors and allow some clearance to prevent door dings or scraping.

The longer body also contributes to a more imposing road presence and improved ride comfort due to a longer wheelbase, though exact wheelbase figures would confirm that. Overall, the new generation brings a more spacious and luxurious experience while maintaining the GLC's agile handling characteristics.
