So, from that article I would infer that the elusive China engine cover with cooling outlet may be making a return. From what I can understand from the article, there seems to be a lot of thought going into cooling for Monaco, and it seems to imply (if my understanding is correct) that the RBR style central hot air exit is because of this.
But surely this would also require a major change of radiator layout to accomodate a whole new cooling approach? In which case, you would imagine this is not simply a Monaco measure, but a more long-term view to improve general airflow.
