Audi RS6 vs Volvo XC90

What's the difference?

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.

The first-generation Volvo XC90 remained on sale for 12 years in Australia before being replaced by the handsome second-gen version that recently clocked up a decade of sales.

There’s a reason for the longevity. People love the Volvo XC90. It is a reliable seven-seat family-friendly SUV with a premium bent. You’ll spot loads of these at fancy private school drop off.

Volvo has extended the life of the second-gen XC90 with a significant late-life update. It adopts some features from its stablemate, the similarly sized and positioned EX90 electric SUV.

It doesn’t get a fully-electric powertrain but you have the choice of a mild-hybrid grade that acts as the range opener and the well-equipped T8 Plug-In Hybrid I’m testing.

Interestingly, a number of this car’s rivals have had their lives extended, too. As many carmakers pour billions into EVs, they’ve taken to delivering major updates to older internal combustion platforms rather than developing all-new underpinnings. The Audi Q7 and BMW X5 are other examples of this.

For the update, Volvo has ushered in a front-end design refresh, a fresh take on the interior, new multimedia and safety tech, a light tweak to suspension and new colours and wheels.

But is this enough to keep premium SUV buyers interested? Let’s find out…
