2025 BMW M Models Summary

To say the BMW M4 CS is a hot ticket in Australia is something of an understatement.

Consider this. There is an even more expensive one, the M4 CS Edition VR46 – at a cool $346,900 – and it sold out in less than an hour. Now, granted, Australia only got four examples, but still, demand was running hot.

That car makes this one, the regular M4 CS, seem like an absolute steal. It's only $254,900 (yes, the word 'only' is doing a lot of heavy lifting in that sentence), and it shares the same upgrades, and makes the same monstrous power, as the VR46 – for Valentino Rossi’s 46th birthday – only it does it for around $100K less.

See? A bargain. At least, that's how I'd be justifying it to myself if I had a quarter of a million burning a hole in my pocket.

So, this or a Porsche 911? Read on.

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?

Verdict

Brutal, bruising and utterly brilliant, the M4 CS will be an acquired taste due to its no-compromise approach, but those willing to take the leap will find a performance car like few others at their disposal.

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.
