A new front wing for Alonso's Renault R29

Apart from a whole range of changes on the rear end of the car, Renault have also changed their front wing to be more efficient. The above detail image is the new Shangai version for Alonso, while the lower one is that used in the 2 earlier races and by Piquet at Shangai. The latter will undoubtedly soon also have this update once the team finish manufacturing of a second one.
Marked by the arrows is the trailing edge of the main flap, now featuring sharp cuts and a more elaborate gurney flap - the latter painted white as of Saturday's free practice.
