Force India team boss Vijay Mallya admits he is unsure what impact upgrades planned for the Spanish Grand Prix will have as rivals also introduce new parts for the first race back in Europe.
The team evaluated a number of new parts during testing at Mugello last week and will introduce some of those at Catalunya for the fifth round of the season.
While that should allow Force India to make forward progress, Mallya admitted it was hard to predict the impact that the updates will have given that rival teams will also be introducing new parts of their own.
“Now that the European season is upon us, we should be able to bring through more updates to the car,” he said. “That will start this weekend when we run with some of the new parts we evaluated in Mugello last week. However, we have to remember that most teams will make a development step for Barcelona so it remains to be seen how this will impact on our relative performance.
“As well as developments for the car we are pushing hard to maximise the strategies and the drivers are delivering excellent performances in the races. That's so important this year with the margins between the teams so tight. If we can continue to deliver like we did in Bahrain then we should be able to remain in the hunt for points this weekend.”
Testing at Mugello didn't go completely to plan for the team with technical problems sidelining di Resta for much of the second day, and the Scot admitting there was still work to be done in practice as a result.
“We didn't do a massive number of laps but it was a chance to start evaluating some of our car developments,” he said. “There's still plenty of work to do in free practice to get on top of the car, but we've already done the basic checks.
“I probably know Barcelona better than any other track on the calendar. We did two tests there in the winter and I had four days in the car so I already feel quite well prepared, but it's the same for everyone. I expect the field to be incredibly close once again.”
