Ferrari technical chief Pat Fry said the team has to find more single lap pace if it wants to challenge for the front end of the grid in Abu Dhabi this weekend.
Fernando Alonso and Felipe Massa were seventh and eighth on the times after Friday practice at Yas Marina, although both showed encouraging pace when on longer runs towards the end of the second session.
The team introduced a series of upgrades for the Abu Dhabi weekend in an effort to try and help Alonso reclaim the championship lead from Sebastian Vettel and while Fry said there has been a postive result from running some of the new parts, he also said the team needed to find more paceto help its drivers.
"We are pushing as hard as we can to bring updates to every race,” he said. “Some of the ones we introduced here seem to be positive, but we must carefully evaluate their performance and then decide which to use in qualifying and the race. Felipe's long run didn't seem too bad, but clearly we have to improve our performance over a single lap if we want to start from the front row of the grid."
Alonso himself wasn't overly concerned by lap times, insisting that the weekend had started like every other, with the real business starting on Saturday.
"The day just ended was a Friday like any other, during which we got through everything on our programme,” he said. “The morning session was dedicated to a comparison of various aerodynamic solutions, while in the afternoon, we concentrated on the tyres.
“Between the first and second sessions, the track changed a lot, which to be honest was predictable, because there aren't many races here over the weekend: at the start, it seemed very dirty but then it improved a lot and tomorrow, it will definitely be even better."
