NEW CHALLENGE, OLD SOLUTION
Like most other cars, the new Ferrari sports a shark fin engine cover. The device is making a return in the sport, with teams seeking to clean up the air flowing towards the lower rear wing.
The latter is more exposed to dirty air, as flows on both sides of the engine cover meet at the back of it and create turbulences.
The flat shark fin helps ‘straighten’ the two streams, which then merge into a flow that is more laminar (see blue lines on the image above). Fed with cleaner air, the lower rear wing can produce more downforce.
