Mercedes-Benz GLB-Class vs Mercedes-Benz GLC-Class

What's the difference?

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.

A mid-life update that arrived in 2023 brought some minor tweaks including different exterior and interior styling, along with mild-hybrid power for certain variants.

On test here is the entry-level GLB200 which didn’t receive mild-hybrid assistance. Read along to find out whether it’s the pick of the line-up.

Let’s make one thing clear from the very beginning - this new Mercedes-AMG GLC63 S E Performance is technically superior to the model it replaces. Whether it’s actually better or not, is the real question at the heart of the matter.

Why? Because, like the C63 sedan stablemate, AMG has opted to replace the previous model’s 4.0-litre twin-turbo V8 engine with a new 2.0-litre four-cylinder hybrid powertrain. It was a move brought about in part because of increasingly stricter emissions standards in Europe, but also ties-in with the German firm’s success in modern Formula One racing.

While the new hybrid system offers more power, more torque and better fuel economy, as the lukewarm response to the C63 has demonstrated, the hard reality for AMG is that its buyers associate it with V8 and even V12 engines. That emotional pull is hard to replace with logic, even if the new model offers technical superiority.

But how does the new powertrain suit the GLC63 - is it just technically better or is it holistically improved?
