2021 Mercedes-AMG GLE53 Summary

You might have some traditional notions of what a 'sports car' is.

Low and light, slick and aerodynamic, purely mechanical and centred around the driver. These notions may have held true for a long time, but in an age where Lamborghini makes a Touareg-based super SUV is there room for those parameters to move?

Especially with consumer sentiment indicating the somewhat oxymoronic idea of a low-slung coupe SUV with an AMG powertrain is more than just a niche.

Mercedes told us the previous generation GLE coupe was a major success, amassing up to 25 per cent of the model line's sales split, and its research indicated  a buyer of this massive SUV was drawn to its "performance, style and technology" and was even "a motorsport fan."

Sounds like this buyer would have once been looking for a 'sports car' and like it or not, performance coupe SUVs are here to stay. But does the new GLE 53 Coupe really make for a compelling experience behind the wheel? We found out at its local launch.

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.
