Mercedes-Benz A-Class vs Peugeot 408

What's the difference?

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.

Unveiled globally in 2022 before arriving here in late 2024 as a plug-in hybrid GT, the Peugeot 408 has been a niche player for the long-established French brand with less than 100 examples finding homes here last year.

But 2025 marked the transition to a new ‘plug-less’ mild-hybrid powertrain for the mid-size crossover-style SUV with the hope it may take a bigger swing at segment heavyweights.

We spent a week with the current 408 GT Premium Hybrid to see if its efficiency-focused petrol-electric set-up has what it takes to win a spot on your upscale five-seat SUV shopping list.
