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…

2023 Lexus NX250 Summary

As far as clichés go, attempting to make “a silk purse from a sow’s ear” couldn’t be more apt than when contemplating the original NX of 2014.

What was essentially the Lexus-fication of the vocal, fidgety and thirsty old Toyota RAV4 may have worked a treat sales-wise, but proved trickier when assessed against the lens of a BMW X3, Audi Q5 and Volvo XC60 rival.

The earliest NX just wasn’t refined enough.

This was especially true following the reborn RAV4 arrival in 2019, proving to be embarrassingly more competent – even compared to most luxury midsized SUV alternatives.

Now, finally, the NX redesign has followed suit, moving on to a variation of the Toyota’s stronger, quieter and more advanced TNGA architecture (dubbed GA-K) as a starting base.

Speaking of which, let’s dive straight into the least-expensive version, the NX 250 Luxury 2WD auto, to find out if the most popular Lexus model in Australia has finally found its mojo.

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.

Verdict

So, is the cheapest Lexus NX the grade you’d skip? Depends on where you live and drive.

If you’re urban based and bound, save up a bit more and go the petrol-electric hybrid; otherwise, out on country roads especially, the spirited and sporty NX 250 is more than up to the task.

Either way, though, the latest NX is finally fit to fight the other premium brands’ medium SUV efforts, head on and held up high. Welcome to big mid league, Lexus.

Ignore or underestimate at your own peril, everybody else.
