Fiat 500X vs Audi RS Q3

What's the difference?

Fiat's indomitable 500 is one of the great survivors - not even VW's recently deceased New Beetle could keep riding the nostalgia wave, partly because it made itself just that little bit out-of-touch by not being a car anyone can buy. The 500 avoided that, particularly in its home market, and is still going strong.

Fiat added the 500X compact SUV a few years ago and at first I thought it was a daft idea. It's a polarising car, partly because some people complain it's capitalising on the 500's history. Well, duh. It's worked out well for Mini, so why not?

I've driven one every year for the last couple so I was keen to see what's up and whether it's still one of the weirdest cars on the road.

Is 10 years long enough for a special birthday celebration? When you're a kid, hitting 'double figures' is a pretty big deal, and Audi's obviously in the mood to make some noise because it has lit the candles on a limited 10th anniversary version of its compact SUV rocket ship, the RS Q3.

Only 555 examples of the 'RS Q3 Sportback edition 10 years' will be produced for worldwide consumption, with Audi Australia capturing a batch of them and sending one our way for a brief blast as the fiery five-cylinder starts filtering into dealerships.
