Sahara Force India completed its second week of Formula One pre-season testing with lead driver Paul Di Resta exuding confidence in car's pace, specially in long runs.
Resta completed 101 laps on the fourth and final day and the fastest came in 1:23.119 minutes.
"I had a small trip through the gravel in the morning, but nothing that caused too much of an issue, although we lost half an hour of running. The important thing is that we still managed to do our long runs in the afternoon and I could feel the changes we made compared to yesterday."
"It's given me a good impression of the car's balance and consistency, and we've seen that our long run pace is improving step by step," he said.
Chief Engineer Jakob Andreasen was satisfied with the way the car has behaved and the way the drivers are getting used to it.
"We've built up some good knowledge of all the dry tyre compounds, collected lots of aero data and given the drivers a good opportunity to experiment with setting up the car."
"What is encouraging is the feedback from both Nico and Paul, which is positive about the handling of the car, especially over longer runs. It's good to hear those comments at a high-speed aero circuit such as Barcelona, which suggests our development steps are leading us in the right direction," he said.
