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.

2021 Audi A4 Summary

The Audi A4 allroad is the off-roader of the A4 line-up. I’m using the term ‘off-roader’ loosely here because this wagon is obviously best suited to daily duties in a city and suburbs, with perhaps an occasional foray into very light off-roading, i.e. driving on a well-maintained gravel or dirt road with few, if any, corrugations, and in dry weather only. 

But that’s not a negative factor because the great thing about adventures is that they can be scaled to suit you, your lifestyle and your vehicle of choice.

However, is this allroad your best option for a comfortable, nice-driving all-rounder? Read on.
