Adrian Sutil sure Force India's strong German Grand Prix form was not a one-off

The Silverstone-based team has become increasingly competitive during the previous four races, with Sutil qualifying eighth and finishing sixth in Germany and Paul di Resta running in the top six in both the British and Canadian Grands Prix.

Sutil believes that the car is now a regular top 10 contender and that Force India is capable of putting together a good run of points finishes.

"We have made some steps during the last few races," said Sutil. "At Silverstone, we had the chance to be around the top eight with both cars, but we missed this opportunity because of the strategy. But we did it again at the Nurburgring.

"That was the true performance of the car. It was very strong in the race and in qualifying. Now we are looking quite strong and we want to keep this level of performance, or maybe even do better. There are a few good races coming up for us and we are on the right track."

The German, who has scored 18 points in the last five races, believes that his strong result in his home grand prix will give the team added impetus as it heads into the final nine races of the season.

After a slow start to the year, the team introduced a radical new aerodynamic package during practice for the Spanish Grand Prix, racing it for the first time in the next event in Monaco.

Sutil believes that this development path will allow it to continue its run of form in the second half of 2011.

"It's good for the team to have a good result finally so that everyone knows that we are at the beginning of a good run of races to the end of the season," said Sutil. "The momentum is there; sometimes you need a bit of success to build on.

"We are on the right course with the car, but we still have to catch up. We need to maximise all of our potential."
