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…

2022 Mercedes-Benz CLS53 Summary

Mercedes-Benz loves to fill a niche. This is the company, after all, that has a coupe version of its GLC and GLE SUVS, four-door coupes ranging in size from the CLA to the AMG GT 4-door, and enough electric vehicles to make Tesla jealous.

The nichest of all though, might the CLS, which has been updated for the 2022 model year.

Positioned above the E-Class but below the S-Class in the line-up as a sporty sedan for customers after a blend of style, technology and performance, the new CLS is available in just one engine now, while styling and equipment have also been tweaked in the update.

Can the CLS earn its place in the Mercedes line-up or is it destined to be a bit player amongst more popular models?
