Pirelli's Paul Hembery says everyone in F1 needs to do better job in wake of Testgate

Pirelli boss Paul Hembery believes everyone in Formula 1 can learn learns from the Testgate affair and has reiterated the need for the tyre supplier to have access to a more up-to-date car.

The Barcelona test has been one of a number of controversies and rows Pirelli have found themselves at the centre of this season with tyres having been the dominant paddock topic of conversation all year. While Hembery is confident they won't now have to introduce revised compounds or constructions for this year to resolve the recent spate of delaminations following a change to their in-house production process, he says the possibiluty to complete in-season tyre testing with up-to-date cars and race drivers going forwards is imperative. He's therefore hopeful that plans which are already affot to relax F1's testing restrictions for next year can work in Pirelli's favour. "You've got to bear in mind that in-season we don't really like to change things because teams make technical decisions on the data they get before the year and they make design decisions based on that," Hembery explained. "It's been one of the issues this year that some have maybe wanted us to make changes because they want to gain a performance advantage, but we believe that we'll actually remain with the current product. We had some of the tread detachment issues - we've had 13 this year in 9,500 tyres, which is too many and doesn't look good for us. So we've worked on that and we believe for Silverstone we now have a solution that retains the current product. "But we need to have some proper testing and maybe there is light at the end of the tunnel because there is talk next year of having some in-season testing staying on after four races with all the teams and maybe if we can find a way of using that, maybe if we can get a few times to run a second car, that might well be a way that we can have some representative running. "You need the correct cars and you need the top drivers. You need to be pushing the product to its extremes because that allows us to understand where we are. Running as we are now with a 2010 Renault, you turn up for the start of the season with cars that you're not sure what developments they've had, what jumps they've made in terms of performance. "It's really very difficult from our point of view. So if we can get as close as we can to the performance of the current cars that will make our life a lot easier and make sure that we do a better job."
