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.

2018 Hyundai I40 Summary

A wagon and not an SUV, eh? Respect. You see, when most people now think of a new car they think of an SUV, especially when they want something with a bit of cargo space. But not you. 

And for thinking outside the box you’ll be rewarded with something that’s better to drive than most SUVs – like the Hyundai i40 Tourer in the Active grade and a diesel engine we’ve road tested here.

So, what are the strengths and weaknesses of this Korean wagon, and should you wait or buy it now? Read on to find out.
