Christian Horner says F1 is not doing enough to help new teams attempting to enter the sport.
The past three years have seen the three new teams from 2010 - HRT, Caterham and Marussia - all disappear from the grid, though the latter has since returned as Manor. While Haas will join the grid in 2016, it has a major partnership in place with Ferrari which is aiding its cause.
With the Strategy Group having discussed a number of changes to F1, Horner says one area which has been neglected is helping facilitate the arrival of any new teams.
"I don’t think anything we discussed has made it any easier for teams to come into F1 because the idea of a customer or franchise car was rejected," Horner said. "I can’t see that it will get any easier."
When asked if there were any other ideas discussed which could help new teams looking to join the sport, Horner replied: "I think there was a proposal for a budget cap with freedom of wind tunnel and testing, but that is like putting an alcoholic in a wine cellar…"
F1i understands just two teams registered an interest with the FIA to join the grid in 2016 or 2017 following a new tender which closed on June 30.
