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.

2020 Mercedes-Benz Glb250 Summary

We all know by now Mercedes-Benz loves to fill a niche, and if it can't find a niche to fill, it will create one. So, please welcome its latest niche-filler, the GLB.

Despite shaping up as a mid-sizer, the GLB is a small SUV… with a twist. Whereas other small SUVs have five seats, the GLB has seven, lending itself to unrivalled practicality.

So, does the GLB operate in the 'Goldilocks Zone', or is it an answer to a question no-one asked? We put its mid-range GLB 250 variant to test to find out.
