Summary


The Mercedes-AMG GLB 35 is a compact performance SUV which sits above the regular GLB range in the Mercedes-Benz line-up.

A four-wheel drive model powered by 2.0-litre petrol engine paired with an eight-speed automatic gearbox, the GLB 35 stands out from the rest of the growing compact performance SUV pack thanks to its standard seven-seat configuration. However, reviewers frequently comment that the extra third row of seats is anything but spacious.

“It’s surprisingly cramped”, says Sean Carson of Auto Express, so it is “best thought of as a five-seat hot SUV with occasional seven-seat capability.”

Several outlets criticise the car’s driver appeal too, explaining that while the GLB 35 is nice to look at and fast off the line, it can be rather subdued on the road.

The Carwow team comments that the SUV’s “high seating position dulls your sense of speed”, while Top Gear instead recommends practical but sporty estate cars like the BMW 330d Touring or Volkswagen Golf R Estate, as they are “much more satisfying to drive”.

As of January 2024, the Mercedes-AMG GLB 35 holds a New Car Expert Rating of D, with a score of 58%. Although its safety score is good, its CO2 emissions are only average while its running costs are very high. And, for a performance model, its media reviews are surprisingly poor.
