Infiniti QX30 vs Mercedes-Benz A-Class

What's the difference?

Tim Robson road tests and reviews the 2016 Infiniti QX30 at its Australian launch with specs, fuel consumption and verdict.

There’s no doubt that the compact crossover segment is a vitally important place for any carmaker to be. Nissan’s luxury arm, Infiniti, is no different, and thanks to a decision from its Japanese masters, the diminutive premium brand will go from having no players on the field to having two marquee players in a matter of just a few months.

The architecturally identical front-wheel-drive Q30 launched only a month ago in three variants, and now it’s the turn of the all-wheel-drive QX30 to take to the pitch.

But is there enough of a difference between the two to actually consider them different cars? Is it adding a layer of complexity for the prospective Infiniti customer? As it turns out, the differences run more than skin deep.

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.
