Force India driver Paul di Resta says that the team needs to improve its one lap pace ahead of qualifying for the Korean Grand Prix.
Di Resta was eleventh quickest in second practice, just a thousandth of a second behind team-mate Adrian Sutil.
“It was quite a successful session and right from the first run I felt in the groove with the car,” he said.
“The long run pace looks promising and our tyre wear seems comparable to our rivals, which is a good sign. The area we need to improve is our one-lap pace so we will work hard tonight and hopefully find some gains ahead of final practice.”
“We worked hard to find the ideal balance and in the morning there was more understeer, while in the afternoon there was more oversteer,” added Sutil.
Reserve driver James Calado replaced di Resta during the first practice session and completed 21 laps, finishing the session in eighteenth place.
“A new track for me and it proved to be quite difficult to learn, especially the last sector, which is quite a challenge with some off-camber corners,” said the GP2 driver.
“The programme involved some high fuel running, which is the first time I’ve done that, and by the end of the session I was feeling very comfortable with the car.”
