Renault rely on developments in Hungary

The reigning world champions have spent time at their factory conducting a thorough examination of exactly what went wrong in Germany last weekend to allow title rivals Ferrari to cruise to a comfortable 1-2 finish.

And in a bid to ensure there is no repeat at the Hungaroring this weekend, they have already decided to take aggressive steps to address the situation.

These include the reintroduction of their mass damper system after an FIA clarification; reverting to an older specification of rear suspension; and taking Michelin up on the offer of a fresh choice of tyres to address the blistering issues the team suffered in Germany.

Renault director of engineering Pat Symonds said: "We received notification on Monday that the FIA will recommend to the Court of Appeal that teams who have used the mass damper in Hungary should not have retrospective penalties applied when the hearing takes place before Turkey. In light of this, we will use the device again in Hungary.

"We have also re-analyzed the other updates added to the car in Germany. A new rear suspension geometry was introduced for this race and in light of the fact that our problems were focused on rear tyre degradation, we will probably revert to the previous specification until we can track test the evolution further.

"However, our substantial new aero package performed in line with our predictions and will be maintained for Hungary, where we hope to demonstrate its true effectiveness."

Speaking about the Michelin situation, Symonds added: "Michelin have responded quickly to the performance in Hockenheim.

"All of the partner teams suffered from blistering to a greater or lesser extent in Germany, and Michelin are therefore offering their partner teams the chance to change one of the tyres that had been selected for Budapest. It has been a fantastic response."

Symonds is confident that the changes made by Renault will see them perform stronger in Hungary.

"This season has been a dangerous one for making predictions, but I am optimistic of a much-improved showing in Hungary. We have not made any knee-jerk reactions to the race in Germany, and this would be the wrong time to be timid and conservative.

"Our approach to the problems has been honest and pragmatic, and it is now up to us to turn things around. Last year, we showed that we can come back and fight a competitor who appeared to be faster than us.

"Hearing people write us off this year has only strengthened our resolve. We will be doing everything in our power to turn the tables on Sunday in Budapest."
