2026 Kia Stonic Summary

This might be Kia's best defence yet against the wave of cheap Chinese SUVs currently crashing against our shores.

It's the Kia Stonic, and this update brings mild hybrid technology, which lowers your fuel bill while upping your power. There's also some new tech stuff and some new safety stuff, as well as a refreshed front-end look.

Critically, though, it's not actually new. The Stonic launched globally back in 2017, before an updated version arrived in Australia around 2021. This is yet another update, albeit a significant one, which means the Stonic has been given dual-cab ute levels of longevity in the market.

All of that should be helping Kia to keep the pencil sharp, with the new range kicking off at $28,180, plus on-road costs.

Not quite China cheap, but not too far off it.

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

Unlike a lot of rivals in this segment, the Stonic's actually quite a bit of fun to drive, and that alone earns it a tick from me.

Yes, it can feel underpowered in places, especially when you're trying to do high-speed overtakes or if you're on a really engaging road and on and off the accelerator. But just cruising around, the little powertrain gives you plenty to get around the city.

And I guess that is the point. This does feel like a very city-friendly vehicle, even if it is undeniably showing its age in places.

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.
