Mercedes GLB review

You’ll have no complaints about the amount of reach and height adjustment that you get with the steering wheel. However, you don’t get adjustable lumbar support unless you go for the top-level AMG Line Premium Plus trim, which brings many extras on top, including full electric seat adjustment with a memory function.

The GLB’s driver’s seat is also narrow enough to make you question whether you’ll still fit if you eat dessert, plus some people will find the non-adjustable lumbar overly firm, and you sit comparatively low in the car, so that you almost feel like you're in a hatchback rather than an SUV. The Land Rover Discovery Sport, by contrast, offers a wide, comfortable seat and the sort of view usually reserved for HGV drivers.

Every GLB gets LED lights all round, including the headlights, and top-spec AMG Line Premium Plus models have adaptive LED headlights, which you can leave on main beam, because they automatically shape their light to avoid dazzling other road users.

As standard, you get a 7.0in infotainment screen with crisp graphics and responsive software. Built-in sat nav, Bluetooth and a DAB radio are all included, while upgrading to AMG Line Premium expands the screen’s size to 10.25in, and adds wireless phone charging as well as Apple CarPlay and Android Auto smartphone mirroring.

Whatever the screen size, it can be operated either as a touchscreen or via a touchpad controller (similar to a laptop's) between the front seats. The latter method is less distracting when you're driving, and gives the GLB an advantage over pure touchscreen systems like the one in the Discovery Sport.
