Formula One's rebel carmakers have met FIA president Max Mosley for the first time since December to discuss future rules and regulations for the sport.
Mosley has been a divisive figure in F1 this season
The meeting represented the first talks between the two sides since seven teams expressed doubts over their continued involvement in F1 beyond 2007.
"It was very good," said McLaren chief executive Martin Whitmarsh.
"Both sides were able to establish they were much closer to one another than perhaps had been supposed."
A spokesman for the FIA, motorsport's governing body, also described the meeting in Cannes as positive.
Three teams - Ferrari, Jordan and Red Bull - have remained in talks with the FIA all along and committed their future beyond 2007, but the others refused to enter into discussions until now.
The meeting was attended by BMW board member Burkhard Goeschel, McLaren boss Ron Dennis, and Toyota's Tsutomu Tomita and John Howett on behalf of the manufacturers and teams.
The carmakers - Renault, BMW, Daimler-Chrysler, Honda and Toyota - recently formed the Grand Prix Manufacturers' Association (GPMA) to replace the now-defunct Grand Prix World Championship.
The GPMA submitted a package of preferred rules to Mosley on Monday. However, Friday's talks did not deal with F1's commercial issues.
