McLaren MP4-23 - nosecone winglets 01 August 2008

These horn-like winglets halfway up the MP4-23's nosecone have been introduced by McLaren in Hungary. It's a solution not dissimilar to the 'delta' winglets on the BMW Sauber and one that provides a better quality of airflow to the car's sidepod inlets and rear end. It does this by improving the management of the airflow exiting the front wing. This doesn't directly increase front downforce, but instead improves the aero efficiency and downforce load in the central and rear sections of the car.
