Renault to push harder in races now

Renault boss Eric Boullier thinks that his team can set its sights on pushing even harder in the races now - after Robert Kubica's breakthrough podium finish in the Australian Grand Prix.

Kubica delivered a brilliant performance at Albert Park to hold off race-long pressure from Lewis Hamilton and Felipe Massa and grab his first podium for his new team.

And with the outfit now understanding exactly how quick its car is, and getting a better grip on tyre strategies, Boullier thinks Renault can lift its performance up a gear in future races.

"Obviously we knew already that our car has good race pace, and is a consistent one, but it was a question mark about tyre degradation," Boullier told AUTOSPORT.

"Now we know so we can push on with a little bit more."

Boullier believes that the podium finish, which comes after a troubled spell for Renault after the Singapore GP crash scandal and a winter of uncertainty about its future, will help spur team personnel on even more.

"We know our car has the pace to be at least just behind the big top four, so obviously any mess up front we can take the opportunity to score points.

"Obviously I am very, very happy with the team at Enstone and Viry-Chatillon because they did an awesome job during the winter, and it is good to have some points and podiums. The target is done, but it helps morale to be even better."

Reflecting on the importance of the victory after the troubled winter, Boullier said: "Of course it was difficult because they are racer people.

"When you don't have results you are just flat. On top of all of this we had the stories, and the change of control of the company – so as we have been saying for three months, I wanted this team to be head down, working and to do what we know is the best – racing. So to be on the podium is great for them."

Brembo denies Vettel's brake failure

Brake manufacturer Brembo has denied reports that Sebastian Vettel's retirement from the Australian Grand Prix was caused by a brake failure.

The Red Bull Racing driver retired from the Melbourne event while leading comfortably, after he suffered a mechanical problem on his front left wheel.

Red Bull's brake supplier Brembo issued a statement on Tuesday clarifying that the failure had nothing to do with the brakes.

The company said Red Bull had confirmed a torque drive between the front left axle and wheel has been lost.

"With regard to the retirement of the Red Bull Racing's driver Sebastian Vettel during the Grand Prix of Australia, Brembo communicates that the cause of his exit in Turn 13 was not caused by the braking system supplied by Brembo, as some publications have reported," Brembo said.

"Red Bull Racing has confirmed that Sebastian Vettel retired from the Australian Grand Prix after the torque drive between the front left axle and wheel was lost.

"Post-race investigations revealed the wheel nut was correctly tightened at the pitstop as well as other possible causes of the fault.

"The team has communicated that it's studying a number of solutions at present, which can be implemented for the Malaysian Grand Prix."
