Di Resta aiming for consistent season

The Scot, who was Force India's third driver last year, has been promoted to the racing seat alongside German Adrian Sutil.

Di Resta, last year's DTM champion, conceded there are too many unknowns to set concrete goals.

"I don't want to say exact targets on record as there are so many factors that can come into play," said di Resta. "What I do want to do is to have a positive approach, finish, be consistent and contribute strongly to the team's overall performance.

"We've got high aims of finishing in a good Constructors' Championship position and I know that I've got to play my part in this."

Sutil is also upbeat about the upcoming season, the German confident that the new VJM04 unveiled today will help the team take another step forward.

"I'm genuinely excited about the 2011 season," he said. "I just missed out on the top 10 last year in the drivers' standings - I'm pretty hopeful I can get in there this season!

"The progress the team has shown over the past two years has been very impressive and what I've seen in the factory and at the wind-tunnel over the past weeks indicates that the rate will continue this year.

"I feel very good and confident; the team and I know each other very well and we know how to get the most from each other."
