BMW’s X5 is on its fourth generation. It’s always been at the sporty end of the SUV spectrum, driving with a verve and agility that most rivals struggled to match.

We’ve also found that past versions of the X5 make very able tow cars.

The latest X5 is bigger than its predecessor, and promises greater efficiency and more high-tech driver aids.

It’s a big and heavy car, and kerb weights north of two tonnes make it a match for just about any van you might want to tow. We’re testing the 30d M Sport.

Is the new X5 practical enough?, we ask. And does it live up to its predecessors by combining a sporty drive with stable towing?
