Mercedes-Benz GLB-Class (2019-present) Pros and Cons

Pros	Cons
Impressive practicality and space	Panoramic sunroof reduces headroom
Seven seats when most rivals have five	Not as capable off road as a Land Rover Discovery Sport
Wow-factor of MBUX infotainment system	The AMG model is a bit OTT

Quick Summary

The Mercedes-Benz GLB-Class (2019-present) is a practical and spacious compact SUV that fills the gap between the GLA and GLC models. With its upright, functional design and seven-seat configuration, it prioritises practicality over style, offering what customers have moved into SUVs to find. The GLB is spun off from the same underpinnings as the A-Class and B-Class, providing excellent interior space in a relatively small footprint. Its MBUX infotainment system is industry-leading, featuring configurable screens and intuitive controls that set it apart from rivals.

To drive, the GLB is pragmatic and competent rather than thrilling, with commendable ride quality, adequate engine performance, and assured steering and braking. Fuel economy is respectable, with the 200d diesel achieving 49.6mpg and the petrol GLB 200 returning 39.2mpg. Running costs are reasonable for a premium badge, with retained values higher than mainstream rivals. The range-topping Mercedes-AMG GLB 35 4Matic offers 302bhp for those seeking more excitement, though servicing and maintenance costs are considerably higher. All-wheel drive is available but the GLB is not designed for serious off-road capability.

Best for: Family buyers seeking maximum practicality and space, those wanting seven seats in a compact SUV, and drivers who value cutting-edge technology and premium quality.

Not ideal for: Off-road enthusiasts, buyers prioritising driving excitement, or those concerned about reduced headroom with a panoramic sunroof fitted.

The GLB is best suited to family buyers prioritising practicality over driving dynamics or off-road capability.
