What are the key safety features of the Mercedes GLB?

Euro NCAP gave the Mercedes GLB a five-star rating in 2019. Standard features include lane keeping and attention assist as well as ISOFIX points for child seats in the third row. Some cars may have advanced features like blind spot monitoring.

What engine options are available with the Mercedes GLB?

GLB models use either a 1.3-litre turbo petrol (GLB 200), 2.0-litre diesel (GLB 200d or 220d) or a 2.0-litre turbo petrol in the AMG 35 performance version. The latter can reach zero to 62mph in just 5.5 seconds. All have automatic gearboxes.

What are the standard technology and infotainment features in the Mercedes GLB?

You’ll find a crisp 10.3-inch infotainment screen, digital driver display, Apple CarPlay and Android Auto as standard. There's also a voice control feature. Top trims may add wireless phone charging and 360-degree cameras.

What is the fuel consumption of the Mercedes GLB?

Official figures for the GLB show around 38 to 50mpg for the diesels and 31 to 39mpg for the petrols. Real-world economy varies with driving style and whether you use all seven seats often, but the diesels usually deliver the best results for everyday use.

What should I check when buying a used Mercedes GLB?

Check for a full service history and inspect the condition of all seven seats, especially the folding mechanism for the third row. Make sure infotainment, cameras and safety systems work as expected and check for any recalls. To feel more confident in your chosen used car, consider booking The AA Vehicle Inspection before buying.

Are Mercedes GLB cars reliable?

The Mercedes GLB performed well in recent reliability surveys, ranking above the likes of the Discovery Sport for dependability. Some minor electrical issues have been reported, but serious problems are rare.

The Mercedes GLB at a glance

The Mercedes GLB was made for families and anyone who needs extra flexibility – it’s one of the few small upmarket SUVs offering seven seats as standard. Launched in 2020, the GLB cleverly slots between the GLA and GLC in Mercedes' SUV range and even offers more interior space than some of the bigger versions. While rivals like the Land Rover Discovery Sport and Skoda Kodiaq offer more boot space, few can match the GLB’s brilliant headroom and easy driving experience. In your chosen used car, you'll find advanced driver assistance and parking aids along with an upgraded infotainment system, too. In summary, the GLB is a way to get a premium badge without the hassle of navigating a huge car.

Pros

Seven seats as standard
Comfortable, premium interior
Strong safety score

Cons

Third row can be tight for adults
Higher running costs
Alternatives have bigger boots

What our AA Mechanics think of the Mercedes GLB

The Mercedes-Benz GLB is a highly useful and extremely comfortable, practical compact SUV, and we love the optional seven-seat layout, which is bound to appeal to young families. It has a premium feel, excellent technology and drives more sharply than its appearance might suggest.
