Sepang, Malaysia - Engine-maker Renault said it was considering quitting Formula One on Friday after its previously successful partnership with Red Bull descending into mud-slinging.
Managing Director Cyril Abiteboul said it was weighing up several options, including buying a team and walking away, a move which could have severe repercussions.
Renault is one of only four engine suppliers in F1, and Red Bull warned it could also be forced out of the sport if the French manufacturer leaves.
"I can confirm that we're looking at a lot of options, including heading out of Formula One," Abiteboul told journalists at the Malaysian Grand Prix.
"Honestly, if Formula One is that bad for Renault's reputation, if we see that we struggle with the current formula, if Formula One is not delivering the value that it costs to Renault.
"Bearing in mind that when you are an engine supplier you have no financial incentive to develop and to fund engine development."
Red Bull also threatened to quit F1 after this month's disappointing season-opener in Australia, when Daniel Ricciardo placed sixth and Daniil Kvyat failed to start.
Frustrated Renault and Red Bull traded insults after the race, with Abiteboul reportedly calling the team's chief designer a liar over comments about the French engine.
Abiteboul tried to play down the row, claiming he was misquoted.
"What goes on tour stays on tour. It's not what I said, let's leave that behind," he said.
