Fiat reckons most of you will buy the 1.6-litre diesel 500X, which can achieve a claimed 68.9mpg and 109g/km – although mid-forties are a more realistic bet. It’s good for 236lb ft and 0-62mph in a respectable 10.5 seconds, so if you can’t abide revvier petrol power (and if you do, avoid the base 1.6), it’s a safe bet. The muddy-trousers 4x4 Cross versions can top £24k before options (you can nudge £30k if you’re really committed), so avoid them like a fake designer handbag. When it comes to 500Xs, less really is more
