2021 Mazda CX-9 Summary

The second-generation Mazda CX-9 may have been on sale in Australia for nearly five years now, but it remains the second best-selling large SUV using unibody construction (as opposed to old-school, off-road-focused body-on-frame).

That said, it is getting on a bit, so Mazda’s given it an update with a twist for 2021, hoping to inject a little bit more life into its flagship model.

And when we say twist, we mean it. After all, who would’ve thought there’d ever be a six-seat CX-9? Well, we’ve checked it out to see if it’s the version we needed all along. Read on.

2026 Audi RS Q8 Summary

Not to spoil the illusion, but at their core the Lamborghini Urus, Bentley Bentayga and Porsche Cayenne all share the same base mechanical DNA. And yet despite their huge price tags and enviable reputation for performance, the fastest SUV isn’t one of them - it’s an Audi.

The new Audi RS Q8 Performance, to be precise, which has lapped the famous Nurburgring in Germany in record time, usurping the Cayenne Turbo GT in the process.

Boasting the most powerful internal combustion engine Audi has ever installed in a production car, ceramic brakes and a highly advanced suspension package, the RS Q8 Performance takes the German brand’s SUVs to a new level of, how do I put this… performance.

So it’s an appropriate name, but is it an appropriate car for Australian buyers looking for something fast, spacious and special? Read on to find out…

Verdict

The CX-9 is still a great option for families looking for a large SUV, even if it is starting to show its age as new rivals continue to launch with newer technologies.

That said, the availability of a luxury-focused six-seat configuration (Azami LE AWD) for the first time might be enough to convince some buyers to give it further consideration.

But for others who need the versatility of seven seats, this is still the CX-9 we’ve all come to know and love – but just a little bit better – particularly in its best-selling Azami AWD form.

Verdict

The Audi RS Q8 Performance is a lot - of everything. It offers lots of power, lots of performance, lots of space and lots of luxury. But it’s also a lot of money, and at more than $250k it’s not going to be on everyone’s shopping list. It’s a very niche proposition for a small group of buyers. For those select few, those who want a lot of everything and who crave the ultimate of whatever product they’re buying, then the RS Q8 Performance is going to be a very tempting proposition - even if they never set any lap record in it.
