Confusion reigns over the future of Formula 1, as several top teams threaten to withdraw from the sport in 2010, or set up a new championship ahead of new rules and budget caps. But while several high profile teams such as Ferrari and Red Bull make at least threats of withdraw, some other iconic motor sport names could be on the way back.

It is believed that March has lodged all the necessary paperwork for consideration of inclusion in the 2010 programme along with teams under the name of Brabham and Lotus. But while the March Racing Organisation application looks straight forward, the Brabham and Lotus teams may not be quite what they seem. Both famous racing names have distinguished histories but pulled out of F1 some years ago. It now appears that in both cases it is the owners of the name rights who have put in entry applications, rather than the former team operators.

In the Brabham case, this means Brabham Grand Prix Ltd., owned by German businessman Franz Hilmer, who bought the assets of the now defunct Super Aguri team. His set up has nothing to do with Jack Brabham or the team he founded, with Sir Jack distancing himself from the proposed entry.

Meanwhile Lotus Cars says it may take legal action against the British F3 team Litespeed who have lodged an entry as Team Lotus. David Hunt, brother of former world champion James Hunt, who apparently owns the Team Lotus name rights, has granted them permission to do so.

Expect even more confusion as team jockey for position for 2010 grid positions.
