2020 Audi A6 Summary

The Subaru Outback has a lot to answer for. Way back in 1994 the Japanese brand created the high-riding wagon scene - and while the idea never really took off with most mainstream makers, European luxury brands seemingly loved the idea of a rugged estate. It’s another niche to fill, after all.

This led to the Volvo V70 Cross Country in 1997, and Audi followed suit with the A6-based Allroad quattro back in 1999.

Other luxury brands have entered the fray since then, and obviously the market has proliferated with SUVs… but they’re not the same as a high-riding station wagon.

There has been evolution in the Audi Allroad line-up over time: in 2015 the company added the smaller A4 Allroad, while the original larger A6-based Allroad wagon continues to cop the rough-and-tumble treatment, as it has for decades now.

So, since the all-new Audi A6 Allroad has just arrived in Australia, we thought we’d see what it’s like. And perhaps more pertinently, maybe we’ll be able to answer the question that many of you probably have: Should you buy a high-riding wagon? Or is it smarter to just buy an SUV?

2025 Audi S3 Summary

In a world where car upgrades often feel like saying, “Can I upsize that?”, it’s refreshing to hop into the updated Audi S3 Sportback.

The flagship RS 3 may still be the holy grail of hot hatch dreams, but with boosted engine outputs and upgraded tech, the S3 is stepping up.

Is the S3 Sportback the smarter pick over pricier rivals? It delivers serious performance and polish without stretching into RS 3 territory. With fierce competition in the segment, let’s see what this contender brings to the table.

Verdict

I was thoroughly impressed by the Audi A6 Allroad 45 TDI quattro 2020 model. It is excellent on road, resolved and comfortable on unsealed surfaces, and very well packaged for family touring.

I’d personally have it in a heartbeat over a Q7 or any SUV, for that matter. I can understand why some buyers wouldn’t consider it, but if you’re someone who likes to think outside of the boxy SUV, then be sure to take a look at the Audi A6 Allroad.

Verdict

The updated Audi S3 Sportback is a fun-sized dynamo with impressive outputs and athletic road manners. It’s missing a few premium features, but its compact size paired with a gutsy engine makes it a compelling option for drivers who don’t want to compromise on performance (just space).
