The latest generation of BMW’s X5 promises strong performance and heavyweight towing ability. Here we’re testing the xDrive 40d M Sport; with 465lb ft of torque from its six-cylinder diesel engine, it should have no trouble pulling any sensibly matched caravan.

We want to see if the X5 is stable and secure at speed, as well as powerful. Also, is today’s X5 practical enough to rival the Land Rover Discovery as a family 4×4? Read the Practical Caravan review to find out.
