Volkswagen Passat vs BMW M Models

What's the difference?

I'm calling it - the Volkswagen Passat is the forgotten hero of station wagons.

It's surprisingly large while retaining the creature comforts and understated styling of old-world glamour.

Then enters the R-Line. A badge that diehard Volkswagen enthusiasts know is synonymous with sporty performance and handling.

However, it can be overlooked for its more affordable rivals, the Mazda6 and Skoda Octavia wagons.

But does affordability take it out of the running for the family market? Or is this the answer for the drivers who don't want to compromise on performance but still have a kid (or three) to throw in the back?

I've been hauling my little family of three around town this week to see what the big blue wagon could do.

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.
