McLaren MP4-23 - revised front winglets 26 August 2008
Like Ferrari, McLaren increased the vertical surface area of the MP4-23's sidepod winglets (see red arrow) in Valencia to maximise their ability to divert airflow. The winglets featured a completely vertical front edge as well as an increased height. This change increases the quantity of air diverted towards the car's rear end and also helps to improve the extraction of hot air from the top of the small venting gills.
