The FIA has revealed the entry list for the F1 2012 season, with 15 drivers out of a possible 24 already confirmed.

Red Bull Racing, McLaren, Ferrari, Mercedes, Sauber and Caterham (formerly Team Lotus) will all field unchanged driver pairings.

Marussia (formerly Marussia Virgin Racing) will bring in Charles Pic alongside Timo Glock, as announced following the season ending Brazilian GP, while the Lotus F1 Team (formerly Lotus Renault GP or Renault) will of course run Kimi Raikkonen, who returns to the sport after spending the last two years competing in the World Rally Championship [see separate story - click here].

Raikkonen's team-mate has still to be announced, possibilities include Vitaly Petrov, Bruno Senna and Romain Grosjean.

Force India, Toro Rosso, Williams and HRT have no named drivers' on the list, although the latter has already announced Pedro de la Rosa. HRT's engine supplier is also listed as TBA.

Paul di Resta and Nico Hulkenberg are expected to make up the Force India line-up, when it is finally revealed by team boss, Vijay Mallya, while Toro Rosso is believed to be considering four drivers' - namely Sebastien Buemi, Jaime Alguersuari, Daniel Ricciardo and Jean-Eric Vergne.

At Williams, Pastor Maldonado is thought certain to stay alongside either Adrian Sutil or GP3 champion Valtteri Bottas.
