BMW X3

As you’d expect, there’s very little to separate the main contenders in this fiercely competitive sector. Take the most popular X3 – the 20d – as your example, and you’ll find that fuel consumption and CO2 emissions are virtually identical to those of the equivalent versions of the Audi Q5 and
Mercedes-Benz GLC and only a shade better than those of the Jaguar F-Pace. There’s very little to separate the rivals on price, either, and because they’re all highly desirable cars with a prestige image, they’ll all hold onto their value with similar stubbornness.

The new plug-in hybrid xDrive30e version meanwhile delivers sub-50g/km CO2 and a pure electric range of over 30 miles, with significant tax advantages for company drivers alongside excellent economy, assuming you drive it with that in mind.
