Ferrari F138 - revised exhaust cooling
In Malaysia Ferrari are again running with no hole in the nose and chassis, and with a very similar configuration to that seen in Melbourne. To cope with the heat of Sepang, the bodywork around the exhausts has been opened up (part of the original F138 project plan) to improve the extraction of hot air from the sidepods (single arrow), over and above the standard set-up (two small arrows).
