VIENNA, Austria - Red Bull fizzy drinks company owner Dietrich Mateschitz says the company will quit Formula 1 if engine supplier Renault doesn't build "a competitive" engine.
Mateschitz told the Austria Press Agency: "We'll only stay in Formula 1 if we have a competitive team and we need a competitive power unit for that. If we can't have one that can race with the best car and the best drivers, we still have no chance of victory."
Mateschitz didn't mention a time frame for improvement. Renault's contract is signed to the end of 2016.
