13599 - Definite progress at Force India - di Resta

The team is aiming for fifth in the constructors' championship this year after a strong finish to last season. The new car impressed onlookers at the opening two tests and di Resta, who completed a shakedown of the second chassis on Thursday, is confident things are moving forward.

"Another busy day and we managed to tick off all the objectives once again," he said. "The final test is all about adding new parts to the car, seeing how they perform, and getting our set-up sorted for Melbourne.

"I think we have a good idea of where we need to be based on the performance of the car today and Nico will continue with that work tomorrow. As I said last week, we are definitely making progress in terms of performance and we're getting a good understanding for the new 2012 tyre constructions."

Chief engineer Jakob Andreasen said updates brought to this week's test were working well.

"As the first race in Melbourne approaches, there are more developments arriving at the track and our task this week is to evaluate as much as we can. The first of those were on the car today, so we carried out some aero passes and had some encouraging feedback from Paul."
