No less than 15 teams have applied for the final place on the 2011 formula one grid.

Italian website 422race.com reports that the governing FIA has now written to all those who expressed interest in the place made vacant by the demise of USF1.

June 21 has been set as the deadline for the teams’ actual application and dossier, at which time EUR12,750 must be paid.

The frontrunners must be successful GP2 team ART, headed by FIA president Jean Todt’s son Nicolas, and the Spanish Le Mans competitor Epsilon Euskadi.

422race.com claims that more than one team may be selected by the FIA, in case HRT or Sauber run further into financial trouble.
