Renault R27 - new front wing 22 July 2007
Introduced at the Nurburgring, this design closely recalls that on the latest BMW Sauber. The differences compared to its predecessor are a squared-off, flatter central spoon section (1), and a deep, 60cm-wide slit (2) in the centre of the main profile. The slit helps to increase the pressure of the airflow passing under the main profile and exiting the flap. The BMW sports a similar slit, but in the flap rather than the main profile. Both solutions tend to provide the same kind of improvements.
