McLaren MP4-21 - nose & no-keel design 28 February 2006
The MP4-21 sports a much narrower nose than its predecessor, modifying the car's centre of aerodynamic pressure. Its front end looks significantly cleaner in terms of airflow management, especially towards the sidepod air inlets, which are smaller and at a higher level than before. These changes work in conjunction with the zero-keel suspension concept retained from the MP4-20, whereby the lower wishbones are connected directly to the lowermost corners of the chassis. Last year this solution proved highly effective aerodynamically, providing plenty of valuable room for airflow passing under the front wing.
