2026 Audi Q3 Summary

Replacing a popular model is fraught with danger. Existing customers will tell you they love it, while focus groups of non-customers will tell you why they hate it and sometimes carmakers get caught trying to appease both groups.

Sometimes they’ll make it too big or change too much in the search for more sales and ultimately end up removing the elements that made it popular in the first place.

Which is why Audi has been extra careful with some subtle evolution for this new-generation Q3 SUV and Sportback. This isn’t just a popular model for Audi Australia, it has been the best-selling model for the German brand for more than five years, so getting it wrong would be a disaster.

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…

Verdict

So is this new Q3 good enough to remain Audi’s number one choice? In a word, yes.

Audi has resisted the temptation that some brands fall into by making too many changes to a proven sales performer. This new Q3 isn’t radically different from the old Q3, but it has improved in almost every way.

It isn’t different enough to widely expand its appeal to a new wave of customers, but there’s no reason it won’t remain Audi’s most popular choice for the foreseeable future.

Verdict

The Audi RS Q8 Performance is a lot - of everything. It offers lots of power, lots of performance, lots of space and lots of luxury. But it’s also a lot of money, and at more than $250k it’s not going to be on everyone’s shopping list. It’s a very niche proposition for a small group of buyers. For those select few, those who want a lot of everything and who crave the ultimate of whatever product they’re buying, then the RS Q8 Performance is going to be a very tempting proposition - even if they never set any lap record in it.
