2025 Kia Stonic Summary

Small SUVs have found plenty of favour in Australia and understandably so because they offer much in the way of urban-driving appeal.

And carmakers like Kia have near-perfected the art of fulfilling drivers' needs and wants and doing so with an end product that’s quite often also easy on the eyes.

But drivers – even drivers of small SUVs – like some poke in their engine. To that end, Kia has punched some turbocharged oomph into its Stonic line-up with the introduction of the 1.0-litre, three-cylinder turbo-petrol engine previously offered only in the top-spec GT-Line.

Now there’s also more safety gear onboard than in previous versions, but – of course – prices have increased, as well.

2024 Mazda CX-30 Summary

If you’re in the market for a city- and family-friendly compact SUV, you’re in luck.

The small SUV segment is one of the most heavily populated and hotly contested in the Aussie new-car market and the Mazda CX-30 G25 GT SP FWD is pitched against a seething pack of at least 10 similarly sized, generously specified and highly-credentialed competitors. 

So, stay with us on a mission to determine whether this high-end version of one of Mazda’s best sellers is worthy of a spot on your new-car short list.
