Scuderia Toro Rosso team principal Franz Tost believes that Renault is no longer interested in buying the Red Bull B-team, and has now turned its attention to another operation.
Renault is known to be re-evaluating its involvement in Formula 1 following a turbulent spell as an engine supplier to Red Bull and Toro Rosso.
The French marque is looking to either scale up its operations by reviving its works team, which last raced in 2010, or scale down by withdrawing from F1 altogether.
Toro Rosso and Lotus were identified as teams that Renault could take over earlier this year, and the possibility of becoming a works operation was welcomed by Tost back in March.
However, whilst speculation about Renault returning to Enstone and taking over Lotus has intensified in recent weeks, little more has been said about Toro Rosso.
In an interview with the official F1 website, Tost revealed that he has heard nothing from Renault of late, leading him to believe that its interest has gone cold.
“I can only say what happened in the last months in connection with Renault and Toro Rosso,” Tost said.
“Yes, they have visited us in Faenza and Bicester but in the last weeks it has been quiet so I assume that they have decided to buy another team. How that would influence Toro Rosso we have to see.
“We have to wait for Renault’s move and announcement. Then we have to discuss a program that fits the requests and needs of Toro Rosso.”
Toro Rosso’s future largely depends on that of parent company Red Bull, with owner Dietrich Mateschitz threatening to withdraw from F1 unless changes are made to the sport for the future.
