Force India team boss Vijay Mallya says the team has to start scoring points again on a regular basis during the final stages of the 2013 season.
The Silverstone-based team were regular top ten finishes in the first half of the year but have suffered more than most from the changes made to Pirelli's tyres since the British Grand Prix.
Since then, the team has picked up just three points to slip down to sixth in the constructors' championship and Mallya said it was vital for the team to turn things around.
“We are making small steps forward on the one-lap pace and working hard to recapture the race pace we showed earlier in the season,” he said. “Unfortunately, we can't convert our performance into points. In Korea we could have had one or two cars in the battle for points that developed at the end of the race.
“The final five races offer some very different challenges. Some tracks will suit us more than others, but it's vital that we get back to scoring regular points to secure our position in the championship. Suzuka is a big challenge for us, but it's important we keep our heads up and try to put the disappointment of Korea behind us.”
Both Paul di Resta and Adrian Sutil
will hope to recover from tough weekends in Korea, with Sutil hoping to make the most of his previous experience of Suzuka to produce the goods on race day.
“I would say Suzuka is one of my favourite tracks along with Spa,” he said. “The difference is that Suzuka is more technical than Spa because it's narrow and quite bumpy, so I think having more experience of Suzuka can help you make the difference. Because I raced in Japanese Formula Three, I have driven so many laps of this track and I probably know it a little better than some other drivers.
“You need a car that works well in the high-speed corners. The 'S' curves at the start of the lap are beautiful because you can really feel the performance of a Formula One car and the incredible grip you have available. You need to have a car that allows you to find the right flow and rhythm through these corners because you can make up or lose a lot of time through this part of the lap.”
