Red Bull F1 "called for change at engine partners Renault" after an "unacceptable" performance in Sunday's Austrian Grand Prix, according to Alan Baldwin of REUTERS. Four-time world champion Sebastian Vettel "retired from the race at Spielberg with an electronics problem, his third failure to finish this season due to an issue with the new V6 turbo hybrid power unit." Red Bull Team Principal Christian Horner said, "The reliability is unacceptable. The performance is unacceptable. There needs to be change at Renault. It can't continue like this. It's not good for Renault and it's not good for Red Bull." Renault Sport F1 Deputy Managing Dir Rob White said that the French manufacturer, which "started the year well behind Mercedes on performance," knew what "had to be done and progress was being made." White: "The anxiety that Christian feels, and the frustration he feels after a result that is not at the full potential of the performance of car and power unit, is completely understandable and shared by us" (REUTERS, 6/23).
