Mercedes-Benz Glb250 vs Mercedes-Benz GLS-Class

What's the difference?

We all know by now Mercedes-Benz loves to fill a niche, and if it can't find a niche to fill, it will create one. So, please welcome its latest niche-filler, the GLB.

Despite shaping up as a mid-sizer, the GLB is a small SUV… with a twist. Whereas other small SUVs have five seats, the GLB has seven, lending itself to unrivalled practicality.

So, does the GLB operate in the 'Goldilocks Zone', or is it an answer to a question no-one asked? We put its mid-range GLB 250 variant to test to find out.

The ‘Upper Large SUV over $120K’ segment of the Aussie new-car market is what you might call the top end of town, not only in terms of the extravagant models available but also their purchase prices, which stretch well into six figures and require monthly lease payments that rival home mortgages.

It’s where you’ll find some of the most prestigious marques in the automotive world including Rolls-Royce, Aston Martin, Bentley, Ferrari, Lamborghini, Range Rover, Lexus and BMW. And, of course, Mercedes-Benz with its big GLS which represents the flagship of the German manufacturer’s SUV fleet.

It was given a refresh in 2023 with cosmetic and multimedia upgrades along with powertrain enhancements, but there have only been minor changes since then. We were recently entrusted with the keys to the latest GLS to see if the ‘S-Class of SUVs’ leaves any room for improvement.
