Sep.15 (GMM/Inautonews.com) Renault CEO Carlos Ghosn on Tuesday all but confirmed speculation the French carmaker is set to split with F1 partners Red Bull and Toro Rosso.

At the Frankfurt Motor Show, he admitted Renault is “renegotiating” its deals with the two energy drink-owned teams, amid intense speculation the decision to split has already been made.

“We will either exit or run our own team,” confirmed Ghosn, although he did not comment specifically on the talks with the Enstone based team Lotus.

“We are assessing in detail and still having talks,” he added.

What Ghosn did admit was that operating solely as an engine supplier no longer works for Renault.

“When you win, no one notices the engine, and when you lose, you are criticised,” said Ghosn.
