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.

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.

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

The Audi A4 allroad 40 TDI quattro S Tronic is a nice-looking wagon that’s fun to drive.

It’s packed with tech, adequately functional for daily life and it’s also capable enough off-road as long as the driving surface is nothing more challenging than well-maintained gravel or dirt tracks in dry weather, and you’re not planning a rough-and-tumble expedition into remote bushland.

As I mentioned earlier, the great thing about adventures is that you can scale them to suit you and your vehicle and the allroad offers a nice stepping-stone for people who’d like to experience the outdoorsy lifestyle, before perhaps diving deeper into it.
