Infiniti Q30 vs MG S6 EV

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.

BYD, Chery, GWM and MG - one of these Chinese car brands is not like the others.

While the first three all enjoyed major growth in 2025, MG had a year to forget. A flood of new models, rushed into the market with little or no fanfare, resulted in a nearly 20 per cent sales decline, when the brand should have been basking in the same growth as its rivals.

So, the old management has been swept away and MG Australia is attacking 2026 with a fresh outlook and a renewed purpose, fully aware that launching an affordable car and hoping the buyers come is not a sound strategy.

Which is why the brand is making a far more concerted effort with this all-new MGS6 (all one word, likely to avoid copyright issues with Audi). It’s an important model to get right, too, as the electric mid-size SUV is becoming an increasingly popular choice for Australian buyers, as witnessed by the success of the BYD Sealion 7 and Tesla Model Y.

But with those two, plus many more mid-size EV SUVs, including the Kia EV5, GAC Aion V, Geely EX5 and Zeekr 7X (to name a few), to compete with, MG will need to put its best foot forward to give the MGS6 its best chance of success.

This one model alone won’t determine the fortunes of MG in the final reckoning of the year, but if MG wants to turn around its sales numbers and enjoy the same growth as its Chinese rivals, having the MGS6 succeed would be an important step.
