In Europe, the ball head of a towbar is standardized. It is completely round and must have a diameter of 50 mm. All mft products fit on this ball head. The make or model of the vehicle is irrelevant. It also does not matter whether the towbar is rigid, removable, or swiveling.
Some electric cars have special towbars where the ball head is not completely round, but has additional corners, pins, or similar features attached to the ball head. This is to prevent a trailer from being pulled. mft products are not universally compatible with these special towbars. Information can be found with the respective products.
