Design & Presence

The GLB wears Mercedes-Benz cues with a boxy, upright silhouette that deliberately trades sleekness for interior space and presence; it measures around 4.63–4.65 m long and sits taller than many compact rivals, so it looks purposeful rather than dainty. A squared-off tailgate and short overhangs give it a family-SUV vibe that reads as practical and slightly adventurous, while AMG-line and optional trim packages sharpen the stance for buyers who want something sportier. Road presence is strong in town and on the motorway, where the raised driving position aids visibility without feeling trucklike. The styling is a clear signal: this is a premium compact that prioritises usability over flash.

Interior & Usability

The cabin balances Mercedes polish with sensible ergonomics: materials are generally premium up front with soft-touch surfaces and neat contrast stitching, although harder plastics appear in less visible areas to keep costs down. The dashboard can be fitted with the familiar MBUX twin-screen layout and a responsive voice assistant that simplifies everyday tasks like navigation and climate control. Controls are well placed and seats are supportive enough for long drives, while small-item storage and practical touches—cupholders, charging points and sensible door bins—make daily life easier. Overall the GLB feels grown-up without being intimidating to use.

Space & Everyday Practicality

The GLB’s raison d’être is space: with a generous boot of about 565–570 litres it swallows weekly shopping, suitcases and a bulky stroller with ease, and folding the rear seats increases cargo capacity to roughly 1,800 litres for larger loads. The passenger compartment is upright and roomy, offering good headroom and usable rear legroom for adults on shorter trips, and in many markets an optional third row is available for occasional extra passengers. Practical details such as sliding rear seats and clever folding mechanisms boost day-to-day flexibility, so the GLB behaves more like a small MPV when it needs to. For families wanting a compact footprint without compromising load space, it’s a strong offering.

Driving & Handling

Driving the GLB is a study in compromise between comfort and agility: it rides composed over motorway distances and soaks up bumps better than many sportier crossovers, but cornering remains more secure than floaty thanks to precise steering and a stable chassis setup. Powertrains range from modest mild-hybrid petrols and economical diesels to a sharp AMG variant for buyers who prioritise performance, and real-world 0–100 km/h times vary accordingly from around 11–12 seconds in entry-level engines to under 6 seconds in the AMG models. Front-wheel drive is the norm for the mainstream units, with all-wheel drive available for more traction and winter confidence, so the GLB can be tuned to suit daily commutes or longer cross-country runs. In short, it’s more comfortable cruiser than sports car, unless opting for the outright performance version.

Efficiency, Consumption & Range

Economy figures depend on engine choice: the mainstream petrol MHEV units can manage around 6.8–7.6 L/100 km in official testing while diesels sit lower at roughly 5.6–5.9 L/100 km, and real-world consumption is typically 1–2 L/100 km higher in mixed urban use. With fuel tanks ranging from about 52 to 60 litres, expect practical driving ranges of roughly 600–900 km depending on engine and driving style, which makes the GLB competitive for both weekday errands and longer trips. Mild-hybrid assistance smooths start-stop traffic and can shave a little off consumption, but those chasing the best economy will still favour the diesel choices. The takeaway is straightforward: choose the engine to match typical use—city, mixed driving or long-distance cruising.

Assistance & Infotainment

Technology is a strong point: the GLB comes with the MBUX system, large digital displays, smartphone integration and voice control, plus navigation that integrates traffic data and route guidance cleanly into the interface. Driver assistance covers modern essentials such as adaptive cruise, lane-keeping aids and active emergency braking, and more advanced packages add semi-autonomous features and parking assists for stress-free urban manoeuvres. Over-the-air updates keep the software current, and usable menus mean the system rarely feels like a gimmick rather than a tool. In short, the GLB’s kit list reads like what a modern family expects from a premium compact SUV.

Who is it for?

The GLB is aimed at buyers who need the flexibility and space of a small SUV without stepping up to a larger, more expensive model—families, couples with active lifestyles and those who value a higher seating position and practical boot. A wide range of petrol and diesel mild-hybrid engines, front- and all-wheel drive choices, and a performance AMG variant mean it can be configured for frugal commuting, long-distance comfort or outright pace. The Mercedes badge, thoughtful interior packaging and usable tech make it attractive to buyers who want premium feel and practicality in one compact package. If space and everyday usefulness top the shopping list but size must remain city-friendly, the GLB is a convincing contender.
