The Mercedes-Benz GLB is a unique vehicle in the compact SUV market, offering a blend of versatility, luxury and performance. Based on the A-Class hatchback, the GLB offers up to seven seats, making it the perfect choice for families who are looking for both space and style. Unlike most seven-seat SUVs, the GLB occupies a niche segment, offering a more premium and luxurious experience which is synonymous with the Mercedes-Benz brand.

The GLB also comes with a range of engine options, including both petrol and diesel variants. For those looking for a more athletic experience, the Mercedes-AMG GLB 35 4Matic adds a performance edge, making it a truly sporty seven-seater. The optional 4Matic all-wheel drive system provides even greater traction on wet roads.

The Mercedes-Benz GLB is a compelling choice for those looking for a compact yet versatile SUV. It offers a premium experience without compromising on practicality or safety. Whether you're a family in need of extra seats or an individual looking for a luxurious and capable SUV, the GLB is worth considering.

Mercedes-Benz GLB updates and facelifts

The Mercedes-Benz GLB made its debut in 2019, quickly establishing itself as a unique offering in the compact SUV market. Despite its relatively short time on the market, the model has already garnered accolades, including the Best Medium Family Car award for 2021 from Parkers. The GLB has not received any major facelifts as of 2023.

Practicality and style of the car

Though the Mercedes-Benz GLB is a compact SUV, it offers a surprising amount of practicality and versatility. Its boxy design ensures that there's plenty of room for both passengers and cargo. Boot space starts at 150 litres with all seven seats in place, but it expands to a generous 700 litres when the third-row seats are folded down.

If you need even more space, folding down the second-row seats will give you a cavernous 1,680 litres. These figures make the GLB a strong competitor against other seven-seaters like the Volkswagen Tiguan Allspace, which has the same 700-litre capacity with the rear seats folded.

If you are looking to tow, the GLB 200 d and GLB 220 d 4Matic are great options. Both have a braked towing capacity of 2,000kg. Two-wheel-drive models including the GLB 200 d, GLB 200 and GLB 35 4Matic also have braked towing capacities of 1,800kg.

Running costs

The Mercedes-Benz GLB offers a range of efficient engine options, with CO2 emissions as low as 137g/km for the diesel models. This puts some trims of the GLB in a moderate road tax bracket, with costs ranging from £180 to £570 per year, depending on the engine and trim level.

When it comes to insurance, the GLB falls within groups 24–35 out of a maximum of 50, making it generally more affordable to insure than some of its more powerful counterparts.

How a used Mercedes-Benz GLB drives

Whether you're a fan of petrol or diesel engines, the Mercedes-Benz GLB offers a variety of options to suit your needs. Starting with the diesel powertrains, the GLB 200 d features a 2.0-litre four-cylinder engine that produces 150bhp and 320Nm of torque. This results in a 0-62mph time of 9.0 seconds.

If you're looking for even more power, the GLB 220 d delivers 190bhp and 400Nm of torque, achieving a 0-62mph time of 7.6 seconds and a top speed of 135mph.

On the petrol side, the entry-level GLB 200 comes with a 1.3-litre four-cylinder engine, delivering 163bhp and 250Nm of torque. It can go from 0-62mph in 9.1 seconds and has a top speed of 129mph.

For those seeking the ultimate in performance, the Mercedes-AMG GLB 35 4Matic packs a 306bhp 2.0-litre turbocharged petrol engine, capable of accelerating from 0-62mph in just 5.2 seconds and reaching a top speed of 155mph.

When it comes to fuel economy, the GLB doesn't disappoint. The most economical diesel variant, the GLB 200 d, delivers an impressive 49.6mpg on the combined cycle. Even the petrol models are efficient, with the GLB 200 and AMG 35 4Matic returning between 38.7-40.4mpg and 32.5mpg, respectively.

Optional 4Matic all-wheel drive enhances traction on wet roads. There are also various drive modes that allow you to adjust the steering weight to suit different driving conditions.

For families, the GLB comes equipped with ISOFIX child seat anchor points in the second row, ensuring that younger passengers can travel safely.

The GLB's commitment to safety is also backed by its rating. The vehicle received a full five-star rating from Euro NCAP in 2019. It shares its platform with the A-Class and B-Class, both of which have also achieved the maximum score. An adult occupancy score of 92% and child occupancy score of 88% further ensure that this is an ideal choice for families who prioritise safety alongside comfort and performance.
