Heikki Kovalainen believes that finding the right set-up is key to unlocking the potential of Caterham's new upgrades.
The team had hoped to evaluate the new parts in first practice, but an electronics issue for Giedo van der Garde scuppered that plan. Kovalainen nonetheless remains upbeat.
"For me today was pretty good. In the first session we ran a number of the new parts we brought here and then did comparison runs in FP2, as well as trying the soft tyres on a performance run, and a longer stint at the end of the session", he said.
"The key to unlocking the potential of the upgrades is finding the right setup and with the amount of laps we ran over both FP1 and FP2 today we’ve generated enough data to give us a good chance to find something we can work with tomorrow. There’s a long night ahead but everyone’s working harder than ever to keep making progress and hopefully we’ll see some of the results of that tomorrow".
Vitaly Petrov returned to the cockpit for second practice and despite a spin at Turn One, the Russian is confident of a good weekend.
"On my first run we had a few handling issues to sort out so we made some mechanical changes and saw an immediate improvement on the second run", he said.
"By the time we put on the soft tyres the times were getting quicker with every lap and I think we found a balance that’s working for us around here. We’ve generated a lot of data from all the runs we’ve done today on both tyre compounds so even with the problem we had this morning we’ve got through nearly the whole program and are set up ok for the rest of the weekend".
