Mercedes GLB buying guide

What Mercedes GLB trim levels are there?

There are three Mercedes GLB trim levels, with all getting the AMG Line styling pack – 19-inch grey wheels, a chrome-studded grille, straked air vents and exhaust finishers. The standard AMG Line trim comes with LED headlights, a powered tailgate, heated front seats, a reversing camera and two seven-inch screens – one for driving information and one for infotainment.

AMG Line Premium ups the size of the screens to 10.25 inches, filling the panel much more snugly. This spec also gets parking sensors, 64-colour ambient lighting, keyless entry, augmented reality sat nav, wireless phone charging and Apple CarPlay/Android Auto connectivity.

Top-spec AMG Line Premium Plus boasts upgraded headlights, a panoramic sunroof, electrically adjustable front seats and Mercedes’ Driving Assistance package – with tech like blind-spot monitoring, active and evasive steering assistance and traffic sign recognition.

Mercedes GLB interior and technology

If you’ve outgrown the Mercedes A-Class or GLA, you’ll feel right at home in the GLB as it’s very familiar. The interior is very premium-feeling, with cool metal air vents, microfibre suede-like seat upholstery and plush nappa leather on the steering wheel. The big screens add an extra wow factor, but even the standard screens have lots of features and pin-sharp graphics.

There’s very little engine noise, the car is comfortable and every GLB has an automatic gearbox, so driving it is easy and relaxing. It could be the ideal antidote to stressful commutes or fraught family trips.

Mercedes GLB engine range explained

(Most popular) Mercedes GLB 200 petrol

The only standard petrol engine in the GLB range is the best choice if you regularly do short journeys or have a low-ish annual mileage. It’s a 1.3-litre engine with 163hp and a reasonably quick nine-second 0-62mph time, and can return up to 39mpg – a consequence of the GLB’s boxiness and practicality.

Mercedes GLB 200d diesel

Mercedes’ 2.0-litre diesel engine produces 150hp in the GLB 200d, which is enough to match the acceleration time of the 200 petrol. It’s more economical, with up to 50mpg possible, but you’ll need to make sure you do longer journeys from time to time. This engine is available with four-wheel drive, which is optional on the AMG Line Premium trim and standard on the AMG Line Premium Plus trim.

Mercedes GLB 220d diesel

Available on the top two trim levels, the 220d diesel comes with four-wheel drive as standard. Power is up to 190hp and the acceleration time is down to 7.6 seconds, but it returns the same 47mpg fuel economy as the 200d with four-wheel drive. Diesel GLBs with four-wheel drive can tow a 2,000kg braked trailer.

Mercedes-AMG GLB 35 petrol

Someone at Mercedes has decided that everything needs the AMG treatment, even a seven-seat family bus. The AMG GLB 35 has 306hp and a five-second 0-62mph time, which’ll certainly spice up the school run. Fuel economy takes one of the five back seats, as you’ll struggle to achieve 32mpg.


In the UK, all versions of the GLB come with seven seats and AMG Line styling, so your choice will come down to the engine you want and just how much tech you feel you need. It’s been on sale since 2020 and was facelifted in 2023, when the car’s styling was tweaked and the two big screens became standard.

The Mercedes GLB is a little over 4.6 metres long, placing it almost exactly between the GLA and GLC. It’s marginally longer than the Land Rover Discovery Sport but shorter than the Volkswagen Tiguan Allspace. The GLB doesn’t offer much boot space when all seven seats are in place, but has a bigger boot than the C-Class estate as a five-seater.

If you’re mostly going to be doing short journeys or don’t fancy a diesel, pick the GLB 200 petrol. The diesels are best for long-distance drivers, while the AMG GLB 35 might be up your street if you want a family car with attitude.
