Also FIA might tender for more teams:
Jean Todt - “I am not happy for Marussia and Caterham and I sympathize for them, but it has always happened."
“But in 2016 we have a new team coming,” he added, referring to the arrival of the Gene Haas team from the United States. “And we may make a tender again for one or two teams to encourage teams. And try to reduce the costs.”
