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.

2025 Rivian R1S Summary

An American all-electric car brand with a unique take on the automotive industry, an up and down share price and a cheaper model in its future plans. You could be mistaken for thinking I’m talking about Tesla, but I’m not.

Recently CarsGuide got the opportunity to experience an alternative electric car brand, and one that, despite having many similarities to Tesla, is also in many respects its polar opposite.

I’m talking about Rivian, which is very much behind Tesla in terms of sales, market cap and just about every other measure. But what it does have is a compelling line-up of electric vehicles, with plans for expansion, including an eventual entry into Australia.

Back in 2023 we drove the brand’s ute, the R1T, but on a recent trip to Los Angeles we sampled the brand’s other model, the R1S SUV. It was an eye-opener to see how far the brand has come in two years and showcased just how different Rivian is from Tesla.
