Renault boss Eric Boullier has expressed frustration with the amount of income distributed to the teams by F1's commercial rights holders.
"F1 is the only sport where the owner of the commercial rights gets 50 per cent and leaves its participants with the task of finding their own source of income," he said in an interview with France's Auto Hebdo magazine.
In a separate interview with Germany's Auto Motor und Sport, former FIA president Max Mosley is predicting a complicated battle between the teams and F1 chief executive Bernie Ecclestone.
Referring to forthcoming negotiations over the next Concorde Agreement, he said: "The question is whether the teams will still be as united when Bernie lures one or two of them with a special offer.
"It will be fun to watch from the outside for a change," said Mosley.
If I was Bernie, I would offer to distribute the revenue equally to all the teams except the top four
The Briton proposed a fascinating solution to the teams' push for more money and power for his old sparring partner Ecclestone.
"If I was Bernie, I would offer to distribute the revenue equally to all the teams except the top four. The top four can threaten to have their own championship but it would not work.
"When they come back to Bernie and the FIA, they could both say: 'You are welcome, but there is no money left over for you'. The approach would bring the small teams a little bit closer to the big ones," he added.
