The FIA has released on Tuesday the 2011 provisional Formula 1 entry list and six teams are yet to confirm their full driver line-ups.
The top four teams (Red Bull Racing, McLaren, Ferrari and Mercedes) as well as Sauber and Lotus have lodged FIA entries naming two race drivers.
One vacancy is at Renault alongside Robert Kubica, although Vitaly Petrov is expected to stay for a second season.
GP2 series’ champion Venezuelan Pastor Maldonado is yet to be announced at Williams, and Force India failed to nominate a single driver, with Adrian Sutil, Tonio Liuzzi, Paul di Resta and Nico Hulkenberg all reportedly in the running.
Scuderia Toro Rosso's line-up is also officially unconfirmed, even though the Italian team have said Sebastien Buemi and Jaime Alguersuari are staying, alongside Australian rookie Daniel Ricciardo in a Friday practice role.
Veterans Heikki Kovalainen and Jarno Trulli have been listed by Lotus, whose entry has been lodged as 'Team Lotus' amid speculation the Malaysian team might change its name before the start of next season.
Similarly, Renault is still officially 'Renault F1 Team', but Group Lotus could step in as a title and naming sponsor, even though that change could compromise its 2010 Concorde Agreement prize money.
German driver Timo Glock is expected to stay at Virgin, but the British team - now renamed Marussia Virgin Racing in deference to its new Russian supercar co-owner - has not listed a single race driver.
