Force India Team Principal Vijay Mallya believes this weekend's Spanish Grand Prix will be a "pivotal moment" in the season for his team.
Force India have been one of the success stories so far this year and are currently in third place in the Constructors' Championship, thanks to the podium finish in Bahrain from Sergio Perez, and the consistent results of Nico Hulkenberg throughout.
Although Mallya is confident that his team will continue to be competitive at Barcelona and throughout the season, he admitted that it is difficult to predict how things will turn out since most teams will be bringing updates to Catalunya.
"It's encouraging that we have performed well across a wide range of circuits, so I'm optimistic that we can maintain our competitive form in Barcelona," Mallya told crash.net.
"China has never been an especially strong track for us, so to come away with ten points was a very good effort.
"We also expect our car to perform better in warmer conditions and there are some upcoming races that will play more to our strengths. At the same time we know that Formula One never stands still and Barcelona is always a pivotal moment in the development race, but I'm optimistic we can keep up our momentum.
"I think we can feel extremely satisfied with our performance during the first four races. We've been in the points in every race, Sergio has been on the podium and Nico has finished no lower than sixth place. We've already scored 70 percent of the total points we scored in 2013 and that puts us in a fantastic position to potentially enjoy our best season to date."
