2023 Mercedes-Benz A-Class Summary

Think of a Mercedes-AMG and the first words that spring to mind are probably not - understated, efficient and restrained. And yet those are probably the best words to describe the all-new C 43.

Of course, before we go any further it’s important to note that the C 43, even in its previous six-cylinder guise, was never meant to be as wild, raucous or powerful as the C63 flagship - that’s simply not its role in the AMG line-up.

But even so, this new model is a dive into fresh territory for the brand and puts a very different spin on the AMG sports sedan as we know it.

This is a four-cylinder model, complete with a Formula One-derived electric turbocharger, so it lacks the sound and fury you expect from something carrying the ‘AMG’ badge - but that doesn’t mean it’s a bad car, as we’ll explain.

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.

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.
