Overall verdict

"Unless you’re willing to spend mega money on a larger model, we don’t think there’s a more desirable seven-seat SUV on the market. The GLB has got a superb interior and - provided you avoid the AMG model - shouldn’t cost a fortune to run."

Mercedes GLB front

The Mercedes-Benz GLB is yet another SUV, but its clever packaging means it’s significantly smaller than seven-seaters like the Volvo XC90 and Mercedes-Benz GLS.


It’s based on the latest Mercedes-Benz A-Class and B-Class. That’s good news as they’re two of our favourite hatchbacks, with superb interiors and strong engine line-ups. 


The GLB has showroom appeal in the bucketload. It looks really cool, almost like a miniature G-Class (the firm’s old-school Land Rover Defender alternative). There’s a huge three-pointed star on the grille, while high-spec models look particularly classy with big wheels and chrome trim.


Its boxy design translates to a load of interior space, too. Adults will be extremely well looked after in the front, enjoying comfortable seats and a high seating position. There’s loads of head and legroom, too, and it feels like a much bigger SUV.


Things are equally good in the middle row. A pair of adults won’t have any cause for complaint with regards to headroom, and the bench slides backwards and forwards should you need more legroom.


Most Mercedes-Benz GLB models come with seven seats but, if you really need to carry seven people regularly, you’d be better looking for a people carrier (however dull that sounds). The back seats pop up from the boot floor, meaning there’s basically no boot space with them in use. As a five-seater, the GLB’s a very practical SUV.


The engine range is made up of the usual petrol and diesel choices, all paired with a seven- or eight-speed automatic gearbox. We think the diesels suit the GLB well, with the 200d being our engine of choice. The more powerful 220d is tempting but isn’t available with seven seats.


Annoyingly the petrol GLB 200 is let down by its tardy transmission, using the seven- rather than eight-speed ’box. For that reason it’s best avoided. The Mercedes-AMG GLB 35, however, is a lot of fun - with enough pace to challenge the BMW's sporty X2 M35i SUV, and a great soundtrack to boot.


AMG model aside, the GLB refreshingly focuses on comfort rather than being fun to drive. That means it rides very well and feels composed in the corners, although there is a little more lean than you’d get in the A- or B-Class.


Ultimately, the Mercedes-Benz GLB is a very appealing family SUV. It’ll be practical enough for a lot of buyers and it feels extremely premium inside. The biggest issue is the price - the most desirable models cost more than £40,000 when new and, as it’s still a relatively recent model (and it’s in demand), we’re yet to see huge savings on the used market.

Is the Mercedes-Benz GLB right for you?

If you’re looking for a classy car that has room for all the family but don’t want (or need) a massive SUV, the Mercedes-Benz GLB should be high on your shortlist.

What’s the best Mercedes-Benz GLB model/engine to choose?

All GLB models come with seven seats as standard and even the entry level Sport model comes well equipped with 18-inch alloys, a digital instrument display and keyless go as well as Mercedes' Artico artificial leather seats. While this offers all most people will need, the sportier looking AMG Line is only £1500 more so that's the one we'd choose.  The extra equipment such as rear privacy glass and a 180 degree reversing camera make it worth it. 


The engine line-up is small but we'd go for the GLB 200 petrol unless you're covering big miles, in which case the GLB 200 d is best for economy.

What cars are similar to the Mercedes-Benz GLB?

The GLB is unique in that it has seven seats - you usually have to go for a bigger SUV for this. Competitors come in the form of five-seat premium SUVs like the BMW X1, Volvo XC40 and Audi Q3 as well as more mainstream alternatives like the Peugeot 5008 and Volkswagen Tiguan Allspace
