Mercedes-Benz C250 vs Infiniti Q30

What's the difference?

If you’re picturing the premium mid-size segment in Australia, you’re almost certainly picturing Mercedes-Benz. Honestly, the premium carmaker has the kind of powerful and unquestioning stranglehold on the segment that would have despots and dictators turning green with envy.

The C-Class often outsells its nearest competitor by a factor of two to one. Even more impressive, that nearest competitor is another Mercedes, the CLA. Audi and BMW are left off in the middle distance, duking it out for third and fourth place.

So yes, the C-Class is a very important car for Mercedes. And this new one, updated for 2019, is even more so. It’s the first major update in the current car’s four-year lifespan, with a handful of exterior tweaks, some new key cabin technology and, most importantly, a new and clever engine option for its top-selling version.

So is that enough to keep the C-Class at the top of the mid-size pile?

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.
