2026 Audi RS6 Summary

When I say this is a rare review, I’m talking about the kind of rare that means you can’t even buy the car you’re reading about.

The 2026 Audi RS6 Avant GT you’re looking at in the pictures around this story is number 248 of 660. That’s six-hundred and sixty worldwide.

In Australia, there are only 22 RS6 GTs, and they’re all sold - at exorbitant prices, mind you, but we’ll get to that.

The RS6 GT is essentially a production version of the Audi RS6 GTO concept, built in 2020 and inspired by the Audi 90 quattro IMSA GTO race car, which means the RS6 GT carries a lot of ‘90 GTO’ in the way it looks. More on that shortly.

Aside from its extremely limited availability and its design package, there are some mechanical changes to increase the appeal of the RS6 GT, though whether any of its owners will put the on-road (or on-track) ability of this special wagon from Ingolstadt to the test remains to be seen.

A couple of days to live with one of the few RS6 GTs in Australia should reveal how special this car feels, and result in at least one example of the rarity being driven good and proper.

2021 Renault Kadjar Summary

Don’t let people talk you into buying a tiny car just because you live in the city. That’s what I’ve learnt from being a car reviewer and living about eight kilometres from the CBD.

Yes, car spaces are small, or almost non existent, but the people that live there are as full-sized as people elsewhere and they often carry around just as much gear. What you need is a big, little car and the Renault Kadjar is that – a small SUV which is actually bigger than most.

The Kadjar is also French, and that’s appealing to us city folk because even though there are millions of us living in one square metre we like to think of ourselves as different, as individuals, cosmopolitan, metropolitan.

So the Kadjar looks perfect then, right?

Well, it’s good yes… in some ways, but after reading this you might prefer its Japanese cousin, the Nissan Qashqai. Let me explain...
