Ferrari test Red Bull nose bulges
Kimi Raikkonen showed up on track at Valencia with a new nose design, or more correctly with Red Bull's nose bulges glued on top of the F60's usual nose shape. Many other teams - including Toyota - have tried this design idea to analyse its advantages but none have so far come up with such an elegant solution.
The different design is supposedly aimed to prevent air from flowing over the nosecone when the car is turning. The higher side surface will keep help to split airflow on both sides of the nose, helping nose stability under yaw.
I think that Red Bull has a combination aero set up in order for the bulges to take full effect.
