2026 Mercedes-Benz GLB-Class Summary

A new-generation Mercedes-Benz GLB is just around the corner, so the current model is now on its farewell tour.

When it launched in 2019 it stood out from the crowd as a premium small-to-medium SUV with the flexibility of seven seats. Even now no other premium carmaker offers a car that’s a direct rival to this. You need to look at mainstream options instead that are slightly larger.

The Kadjar is also French, and that’s appealing to us city folk because even though there are millions of us living in one square metre we like to think of ourselves as different, as individuals, cosmopolitan, metropolitan.

So the Kadjar looks perfect then, right?

Well, it’s good yes… in some ways, but after reading this you might prefer its Japanese cousin, the Nissan Qashqai. Let me explain...
