Paul Di Resta hopes he can produce the aggression needed to claim a points finish in Sunday's Korean Grand Prix after qualifying in ninth place.
The Scot managed to qualify in the top 10 for the fourth time this season in Saturday's practice.
"It was a good effort from the whole team to get both cars back into Q3," said the 25-year-old.
"We looked quite strong throughout, although we seemed to be very close on performance with the cars around us."
Di Resta starts ninth on Sunday, one place ahead of Force India team-mate Adrian Sutil.
"I couldn't believe how tight it was, with Mercedes underestimating some people's performance, and Michael [Schumacher] only doing one run in Q2.
"But it's good to make Q3 and it puts me in a strong position, especially starting from the clean side of the grid.
"With our focus on competitors in the constructors' championship, being ahead of them, we need to be as aggressive as possible to gain some points.
"There are some fast cars behind us, including a Mercedes, and we need to work hard to keep them at bay."
It is thought that some drivers may need to make four stops on Sunday given concerns about how quickly tyres will degrade.
However, Di Resta is relaxed, adding: "I'm not massively worried about tyres. Given the run we had in final practice, we were quite happy.
"I'm not so sure it's quite as bad as people are predicting and Pirelli have done a very good job on their tyre choice here. They should be credited for that.
"The grip is there, the compounds [the soft and supersoft] are as close as they have ever been, probably about eight or nine tenths [of a second difference], which is the best gap we've had in terms of performance.
"It should show quite well in the race. It's not going to be what people think it is."
