2026 Audi RS Q8 Summary

Not to spoil the illusion, but at their core the Lamborghini Urus, Bentley Bentayga and Porsche Cayenne all share the same base mechanical DNA. And yet despite their huge price tags and enviable reputation for performance, the fastest SUV isn’t one of them - it’s an Audi.

The new Audi RS Q8 Performance, to be precise, which has lapped the famous Nurburgring in Germany in record time, usurping the Cayenne Turbo GT in the process.

Boasting the most powerful internal combustion engine Audi has ever installed in a production car, ceramic brakes and a highly advanced suspension package, the RS Q8 Performance takes the German brand’s SUVs to a new level of, how do I put this… performance.

So it’s an appropriate name, but is it an appropriate car for Australian buyers looking for something fast, spacious and special? Read on to find out…

2026 Mercedes-Benz GLE-Class Summary

Well into its second generation, the Mercedes-Benz GLE remains a key player in the luxury large SUV space.

Though it lags well behind the BMW X5 in terms of sales, by about half in fact, the GLE still aims to exude status and luxury, helped by a facelift in 2023.

In its category, there are however plenty of badges with the power to lure buyers away: Audi, Porsche and Range Rover. Even non-Euros like Genesis and Lexus.

Despite the facelift, the category is moving on with big screens and more tech, where the GLE still has to rely on some traditional charm to win over wallets - especially in our big diesel ‘450d’ guise.

A week behind the wheel around and out of the city should reveal whether the GLE still has a strong-enough USP in 2025.
