Infiniti Q30 vs Mercedes-AMG E63

What's the difference?

Welcome to the future - where your Mercedes-Benz is a Nissan and your Nissan is a Mercedes-Benz. 

Lost already? Let me catch you up. Infiniti is the premium arm of Nissan, in much the same way Lexus is the premium arm of Toyota, and the Q30 is Infiniti’s hatchback. 

Thanks to the state of various global manufacturing alliances the Q30 is mechanically, largely a previous-generation Mercedes-Benz A-Class, with a similar arrangement seeing the new Mercedes-Benz X-Class ute comprised largely of Nissan Navara underpinnings.

Recently, the Q30 has had its range of variants trimmed from a confusing five down to two, and the one we’re testing here is the top-spec Sport.

Make sense? I hope so. The Q30 Sport joined me on an 800km trip along the east coast in the height of summer. So, can it make the most of its German/Japanese roots? Read on to find out.

Feels like lately all the Mercedes-AMG buzz has been at the smaller end of the scale.

Most recently, the screaming GLA 45 S has arrived in Australia, pumping out more kilowatts and newton-metres than any compact SUV has a right to.

But here, we're doubling the cylinder count to eight, arranging them in a vee, and lighting the wick on AMG's powerhouse mid-size sedan, the recently upgraded E 63 S.

While the ferocious twin-turbo V8 and the rest of this beast's powertrain are unchanged, the car has been brought up to speed with some aero-focused styling tweaks, Merc's latest 'Widescreen' digital cockpit, as well as the MBUX multimedia system, and a tricky new multi-function sports steering wheel.
