In Monaco, Ferrari have kept the new diffuser they introduced in Spain. It features curved connections (1) between the vertical middle plate and the trailing edge of the diffuser. The vertical plates are also rounded in their lower section (2) in an effort to improve efficiency and reduce drag. Meanwhile, mini flaps (3) on top of the trailing edge work as a more angled diffuser to create increased downforce. New rear-wing endplates (4) extend low down and feature four vertical gills to reduce drag.
