Jean-Michel Jalinier believes Renault will sign with four teams
Jun.14 (GMM) Renault is still yet to finalise new V6 engine deals with existing customers Caterham and Lotus.
Red Bull and Toro Rosso already under contract for 2014, another customer or two "is the ideal".
It has been reported that while Caterham is expected to stay with Renault, Lotus has been in talks with Ferrari.
"We very likely will end up with four teams," Jalinier is quoted by Reuters this week.
"The discussions with Lotus and Caterham have progressed. It's almost done with them, so there's a high probability that we end up with four in 2014."
