X5 4.0d M Sport F15 (UK model 2017)

[Mike200]

I have posted this question on a different forum and have not had a definitive answer i.e. reference to BMW technical information that confirms the exact specification.

"I have searched for information on the BMW X5 option of 'towing capacity increased', which appears to be standard when the electrically deployed tow bar is selected as a factory option.

I am going to test drive a 2017 X5 tomorrow that has the factory towbar option and would like to know what changes the car has with the 'towing capacity increase' added.

The dealer salesman answered with 'its so you can tow a caravan with more than 2 wheels'. Basically he does not know and can't be bothered to check.

Any further information on the changes appreciated."
