Parkers overall rating: 4 out of 5 4.0
  • Design is largely copied from Mercedes-Benz A-Class
  • Some subtle nods to the G-Class SUV, however
  • Twin screens still feel like the centre point of the cabin

The GLB’s interior is very similar to the A-Class's (and others based on the same basic structure), therefore, the order of the day is crisp, modern, mostly high quality materials, plus plenty of high-end technology on offer. However, certain elements of the cabin, such as the brushed metal grab handles on the doors, and more substantial facia directly in front of the passenger feel like nods to Mercedes’ G-Class SUV.

Much of the cabin’s look also depends on which trim level you go for. As well as cosmetic changes (AMG Line models upwards will get a chunkier sports steering wheel for example), the two dashboard mounted screens (arguably the centre point of the cabin) vary in size.

For example, Sport and AMG Line versions make do with the 7.0-inch digital instrument cluster and 7.0-inch infotainment screen, while AMG Line Premium models upwards get the full 10.25-inch monitors. And while both iterations run the same MBUX software, it’s clear that the GLB cabin has been designed to work best with the larger screens.

MBUX is becoming more familiar throughout the Mercedes-Benz range, with its sharp graphics, speedy processor and seemingly endless functionality – not to mention ‘Hey Mercedes’ voice activation (like Siri, but in your car) and Mercedes me connect. Smart as it is, however, we still reckon that equivalents systems from Audi and BMW are easier to navigate with simpler controls.

All GLBs come as standard with :

  • Cruise control
  • Two-zone climate control
  • 180-degree reversing camera
  • Heated front seats
  • Light and sight interior lighting package
  • Sat-nav
  • Artico man-made leather and Albury fabric upholstery
  • 7.0-inch digital instrument cluster and 7.0-inch infotainment screen
  • Apple CarPlay/Android auto

How comfortable is the GLB?

  • Comfortable standard fit half-leather seats
  • UK cars won’t get air suspension…
  • Worth waiting to see our review of how the car drives in the UK

Naturally, both the driver and passenger sit high up in the GLB’s standard driving position. There’s a broad range of adjustment in both the seat and steering wheel, too, meaning occupants of all heights shouldn’t have any problem getting comfortable. Visibility is decent too, with the car’s boxy profile allowing a mostly uninterrupted view out from all angles.  

We’ve only driven the GLB on the international launch thus far, with every car we tested running on Mercedes-Benz’s adaptive suspension that won’t be available on UK cars (apart from the performance A 35). Instead, all regular variants will have fixed, or passive, suspension. We reckon this could be a cause for concern as the GLB runs on 18-inch wheels as standard, with 19- and 20-inch variants available.

Without adaptive suspension to smooth out the bumps – which it did reasonably well on our European test cars – ride comfort could be on the firm side. That said, we wouldn’t bet against air suspension being quietly introduced as an option on the GLB further down the line, so it’s worth waiting for us to drive a passive suspension car in the UK before considering an order.

Engine refinement is in line with other Mercedes-Benz vehicles – good, but not quite as smooth-sounding as BMW and Audi equivalents, while wind noise in the GLB is a notch up on the A-Class, but still largely unintrusive.
