This weight range reflects the vehicle's solid construction and capability, ensuring safety and performance.

The GLB (X247) offers a ride height or ground clearance of 135 mm (5.31 inches). This clearance is relatively moderate for an SUV, making it suitable for urban and light off-road driving. While not designed for extreme off-roading, it supports confident driving over speed bumps, rough terrain, and unpaved roads.

The GLB (X247) provides a luggage capacity of approximately 565 to 570 liters (19.94 to 20.11 cubic feet) with the rear seats upright. When the rear seats are folded down, the capacity expands dramatically to between 1800 and 1805 liters (63.58 to 63.73 cubic feet). This flexible cargo space is ideal for families or users who need to transport bulky items.

This generation of the GLB comes equipped with rim sizes including 6.5J x 17, 6.5J x 16, and 19 inches depending on configuration. Tire sizes are typically 215/65 R17 or 215/65 R16.

With its dimensions—length of 4634 mm (182.5 inches), width of 1834 mm (72.2 inches) excluding mirrors, and height of 1658 mm (65.3 inches)—the GLB is compact for an SUV and comparable to many midsize vehicles. However, the width with mirrors opened (2020 mm or 79.5 inches) should be considered when parking in narrower garages.

The GLB (X247) replaced the smaller GLA and introduced a larger, more spacious compact SUV option in Mercedes-Benz's lineup rather than being a direct predecessor of identical model names. Compared to the GLA, the GLB is longer at 4634 mm (182.5 inches) versus roughly 4417 mm (173.9 inches) of the GLA, wider, and taller, allowing it to accommodate optional third-row seating. The GLB's design focuses on modular interior space and SUV versatility, delivering more passenger and cargo room with a boxier shape.

Compared to other compact luxury SUVs like the BMW X1, Audi Q3, and Volvo XC40, the GLB (X247) stands out with its slightly larger dimensions and impressive cargo volume. While many competitors measure close to 4400 mm to 4500 mm in length, the GLB's 4634 mm length allows for optional third-row seating and expanded cargo space—offering up to 1805 liters (63.7 cubic feet) with seats folded. It thus caters well to buyers needing flexibility beyond the typical five-seat compact luxury SUV.

The Mercedes-Benz GLB (X247) emphasizes versatility and family-friendly features. It is known for its boxy design that maximizes interior space, available seven-seat configuration, modern infotainment with MBUX system, and advanced safety technology. The GLB balances urban comfort with a raised ride height suitable for some light off-road use, making it a practical choice in the compact luxury SUV segment.

The exterior width of the GLB (X247) without mirrors is 1834 mm (72.2 inches), but with mirrors opened, it widens to 2020 mm (79.5 inches). This is an important consideration for parking, garage clearance, and navigating narrow streets. Mirrors extended offer better visibility and safety but increase the car’s width, so users should be mindful of this when maneuvering in tight spaces.
