Getting back to the original question. I understand that this isn't relevant to the particular model in question. But coincidentally we looked at a 2020 1.7 diesel yesterday with a view to towing. The salesman said that the naximum towing limit for the 1.7 is 2000kg. I checked when I got home and a lot of sites seemed to contradict this, quoting limits already mentioned in this thread. However, with a but of digging, it turned out the salesman was correct. This is from a 2019 Nissan press release
