Audi RS6 vs Lexus LS500H

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.

Almost 30 years after Lexus launched its original LS flagship sedan, the fifth generation of the car has arrived in Australia in what appears to be the brand’s never-ending battle to hunt down and beat Mercedes-Benz, BMW and Audi at their own game.

In some markets it looks as though Lexus is making headway. In the United States last year Mercedes-Benz was the best-selling luxury brand, followed by BMW and then Lexus. To give you even more insight, 50 per cent of all Lexus sales globally are in the US.

The story is different in Australia, with Lexus hardly a threat to the big three Germans, selling about a third less each month.

The Lexus LS is the Japanese prestige brand’s flagship and comes with a price that nudges up against formidable rivals. There’s the Mercedes-Benz S-Class, BMW 7 Series and Audi’s A8. Only the best cars from a few of the best brands in the world – no pressure, Lexus.

This may even be a reason to buy one – in that it’s not one of the traditional three. You could see Lexus as the popular underdog that in some ways does a better job than the usual suspects. A people’s favourite perhaps?

Just look at how often it’s mentioned in songs. According to lyrics.com.au the word Lexus has been used in 873 songs. Meanwhile Mercedes Benz appears in 500, Audi in 402 and BMW in 307.

With all this in mind we headed to the Australian launch to drive the LS 500 and its hybrid twin the 500h.
