The French manufacturer originally had a pre-contract with Andretti for a supply of power units when it first looked at making it onto the grid.
However, that deal lapsed last year and there is currently no formal arrangement with Andretti while it ponders its next steps following FOM’s rejections of its plans last week.
It is understood that Renault remains Andretti’s preferred option for a customer deal if it gets the go-ahead from 2026, prior to it forming any works relationship with Cadillac’s own operation as could happen from 2028.
However, Renault has made it clear that until Andretti gets as far as securing an official entry, then there will be no point in discussing the matter.
Asked by Autosport about the engine situation with Andretti, Alpine VP of motorsport Bruno Famin said at his team's 2024 car launch: “We had a pre-contract and after nothing happened.
“But it was related to the [condition] for Andretti to have this entry. For the time being, they have no entry.
“I read, like you, what FOM said about 2028. Let's see what will be the future after that.”
