Mercedes-Benz C43 vs BMW 4 Series

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.

Without a whole lot of fanfare BMW has slipped yet another model into its Australian line-up.

Sitting alongside existing coupe and convertible variants, the new 4 Series Gran Coupe follows the template established by the previous gen version. 

A sports luxury four-door with a sleek, fastback twist, it provides a more adventurous alternative to its close 3 Series cousin. 

Offered in three grades, this is the M440i xDrive, the 3.0-litre, six-cylinder, all-wheel drive 4 Series Gran Coupe flagship. 

It competes with premium all-wheel drive four-doors like Audi’s S5 Sportback, the Jaguar XF P300 R-Dynamic HSE, and the Mercedes-AMG C 43.
