The 2026 Mercedes-Benz GLB is a masterclass in spatial engineering. While maintaining an agile, city-friendly footprint, it is one of the rare vehicles in its class to offer an optional third row of seating. This specialized addition transforms the GLB from a standard five-passenger vehicle into a highly capable seven-passenger luxury transport. This 50/50-split folding third row is highly compact, making it the perfect solution for accommodating children or extra guests during short trips across town.
The second row is meticulously designed to maximize this utility. It features a 40/20/40-split folding configuration that can slide forward and backward, as well as recline. This allows drivers to instantly prioritize either second-row passenger legroom or rear cargo volume depending on the specific demands of the day. For a complete breakdown of available interior trims and technology features, review our comprehensive 2026 Mercedes-Benz GLB capabilities overview.
When the priority shifts from moving people to moving gear, the GLB delivers exceptional practicality. Even with the optional third row upright, you retain 12.4 cubic feet of space for everyday items. By folding the second and third rows completely flat, the cabin opens up to reveal a maximum of 62.0 cubic feet of total cargo capacity.
This expansive area is shaped perfectly by the upright, boxy exterior design of the vehicle, allowing it to easily swallow bulk groceries, large luggage sets, or bulky finds from local antique shops without compromising the luxurious atmosphere of the cabin. You can verify the exact dimensional measurements and interior layout configurations on the official Mercedes-Benz USA specification portal.
