The provisional 2015 entry list has 22 teams listed, but there's a catch.
Although both Caterham and Marussia have both gone into administration, there's still some hope that they may still return to the grid. Although Caterham is listed on the provisional 2015 entry list, there isn't any solid news regarding a potential buyer.
As for Marussia, their situation looks more optimistic. There's just one catch. On the 2015 entry list, they are listed, but not as 'Marussia.' They are instead called 'Manor F1 Team.' Both teams missed the United States GP and will also miss Interlagos.
It is believed that they will have the investors that will allow them to participate in the season-ending Abu Dhabi GP. Following the withdrawal of Russian backer Andrey Cheglakov, the team is reportedly in advanced negotiations with an Indian buyer.
Manor was part of the original name of this young team, prior to them jumping to F1 and switching to Virgin Racing, then later Marussia.
Lending a helping hand
Lotus team owner Gerard Lopez, who has become the voice for the smaller teams, is directly speaking with Donald Mackenzie, the chairman of F1's major shareholder, CVC. Teams such as Sauber, Lotus, Force India, and the aforementioned Caterham/Marussia could benefit to a potential $160 million boost if the negotiations are indeed successful.
