Helmut Marko conceded that Red Bull's current under performance is to be partly blamed on the teams RB11's chassis.

In the aftermath of the season opener Australian Grand Prix, Red Bull pointed an accusing finger towards engine partner Renault, emphasizing the manufacturer's power unit weaknesses in terms of performance and reliability.

Renault's Cyril Abiteboul was quick to respond, alleging that the team's car had problems of its own, a state of affairs which embroiled the two partners in a nascent public feud.

Marko has now admitted that the Milton Keyes outfit has issues that it also needs to address. " The Sepang result was unfortunate for Red Bull Racing," Marko told Servus TV. "But there is a need to wake up in England as there are some things in the chassis that do not work optimally."

Sunday's race was particularly difficult for both Ricciardo and Kyvat who, amongst other things, encountered early on overheating brake issues. Red Bull's out performance by its Toro Rosso junior squad, which exploits the same Renault power unit as its sister team, underlined the fact that current difficulties cannot be traced to the engine alone.

Helmut Marko said Red Bull's row with Renault was now over and that the two parties have now put their down together to pull the team out of its doldrums.

"We do not have to love each other, but we do need an engine that works," Marko concluded. "We have decided to postpone the debate and focus on working together to get us out of this situation and be able to once again fight at the top."

Phillip van Osten

Motor racing was a backdrop from the outset in Phillip van Osten's life. Born in Southern California, Phillip grew up with the sights and sounds of fast cars thanks to his father, Dick van Osten, an editor and writer for Auto Speed and Sport and Motor Trend. Phillip's passion for racing grew even more when his family moved to Europe and he became acquainted with the extraordinary world of Grand Prix racing. He was an early contributor to the monthly French F1i Magazine, often providing a historic or business perspective on Formula 1's affairs. In 2012, he co-authored along with fellow journalist Pierre Van Vliet the English-language adaptation of a limited edition book devoted to the great Belgian driver Jacky Ickx. He also authored "The American Legacy in Formula 1", a book which recounts the trials and tribulations of American drivers in Grand Prix racing. Phillip is also a commentator for Belgian broadcaster Be.TV for the US Indycar series.
