Ferrari's clever new rear wing design was adjudged to infringe technical guidelines by the FIA, prior to the final Free Practice session this morning.
An extension to the wing was added, but was designed with a 'V' shape cut into the top in an effort to keep it to the strict height regulations. It was, however, decided that this new design could create additional downforce and therefore did not fully meet with the regulations.

However, this appears to have had little effect on Fernando Alonso, who stormed to an impressive fourth place in qualifying. The Spaniard has qualified fifth in every race so far this season, but he claimed that his final lap today was "perfect", and suggested that he wouldn't have been unable to replicate it again if he tried.
