Renault fix rear wing problem

Kovalainen and Giancarlo Fisichella had been forced to share a low-mileage rear wing during testing on Thursday while the team got to the bottom of the structural problem discovered on Wednesday.

But after analysis at the team's Enstone factory, and a big effort from the team on Thursday night, the team were able to resume normal testing activities with two cars today.

Renault's technical director Bob Bell said: "The rear wing is a brand new design, and we noticed a small structural problem this week on two examples, leaving us with just one lower-mileage wing available at the test - which meant we only ran one car at a time on Thursday.

"Obviously, a potential problem with the rear wing assembly can have serious consequences if it fails, so we took a very prudent approach and immediately brought the wings back to Enstone.

"After rigorous analysis, we determined the solution that was required, and the team worked through the night yesterday to implement it. The modified components arrived this morning in Jerez, and the cars were both running again at 09:00."
