Mercedes GLB SUV - Practicality & boot space

The Mercedes GLB’s third row of seats improves flexibility

Practicality & boot space Rating

4.0 out of 5

There may be some initial confusion as to where the GLB sits in relation to the Mercedes GLC, given their similar size, but it's best to think of the GLB as the slightly more utilitarian and family-focused vehicle. It's taller and boxier, and while the GLC is a strict five-seater, the GLB is available with up to seven seats.

Mercedes GLB interior space & storage

The GLB's square, somewhat traditional design, is a big plus when it comes to passenger space. There's heaps of headroom in the front and back, while the long wheelbase means kneeroom is also plentiful and three adults can easily sit in the back. It's competitive with the Land Rover Discovery Sport and Volkswagen Tiguan Allspace for taking on the school run. The third row seats aren't really big enough to accommodate adults but will be fine for most children.

Boot space

Luggage space for the five-seater comes in at 570 litres - 20 litres more than the GLC, although this does drop to 500 litres for the seven-seat model because the boot isn't as deep once the extra chairs are folded into the floor. With all seven seats in use, there's very little loading space, making the Discovery Sport feel a bit more spacious in this scenario.

Towing

The Mercedes GLB should be quite an accomplished tow vehicle, with braked trailer limits of 1,800kg for the 200 and 200d, increasing to 2,000kg for the 200d 4MATIC and 220d 4MATIC. This is easily enough to tow a caravan, but for really heavy trailers a Land Rover Discovery Sport pips it, with a capacity of up to 2,500kg.
