The FIA's proposed budget cap looks like it is having the desired effect as several teams are considering a return to Formula One.
Super Aguri have become the latest team to hint that they might give F1 another go next season.
The Honda-powered team withdrew from last year's Championship after running into financial difficulties. However, former team owner Aguri Suzuki has told Japanese media that a return to F1 could be on the cards.
"If it's physically possible I would certainly like to (return to Formula One)," Suzuki told the Sankei Sports.
Prodrive and Lola have already indicated that they are tempted to return after the FIA decided to implement a £40million budget cap.
The FIA also announced there would be space for three new teams on the 2010 grid, potentially increasing the number of cars to 26.
