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?

2024 Audi RS4 Summary

It's the end of the line for that Audi A4 as we know it. In saying goodbye to the ‘B9’ generation A4 that launched in 2015, we welcome the Audi RS4 Competition Plus.

It is the most hardcore example of the breed yet, sitting lower to the floor with hard-edged gear changes, lightweight wheels and snuggly bucket seats. You can also get it in swoopy RS5 Sportback guise.

Audi is only bringing 75 units of each down under as a swan song for the B9 generation RS4 and RS5 before the even-numbered model moves into its all-electric future.

As we’ll go on to discover, these two special models see the A4 and A5 bow out in style.

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

What a way to send off this generation of Audi RS4 and RS5. The extra focus courtesy of those trick coil overs and drama from the exhaust plus the sharper gear changes deliver the best Audi has done with these RS products.

There are some compromises, with the suspension favouring outright control over low-speed comfort. It’s also true that the current BMW’s M3 and M4 are more impressive, but when the products are nearly seven years fresher than Audi’s, what do you expect?

Plus, those looking for a more restrained and polite fast executive sedan (or wagon) will gel with the Audi’s sophistication. There aren’t many of these Competition Plus RS4 and RS5s coming to Australia and they are impressive visually and from behind the wheel. It’s a fitting way to send off the current generations.
