When it comes to towing capacity you really do have to check the manufacturers details, as what might appear to be a model with the same engine can have quite different towed weight and nose load limits. Some more powerful sporting variants are not even allowed to tow anything!Ouch, you would think the xc90 would have been a lot higher, just shows you never take things for granted .
Sometimes something as small as a trim level can change the maximum towed weight limit of the model.
