McLaren may be in the lead of the constructors' championship and also at the head of the drivers' tables, but the team is still pushing development on every aspect of the car possible, test driver Pedro de la Rosa has said.
"The objective is not only to continue to fight; it is to win the championships," de la Rosa said. "The team that will win the championship is the team that will develop their car better and faster whilst maintaining high reliability. Our reliability so far has been good, but it is important that we continue to finish races. We have to continue with the hard work, and have to make sure that any new parts we introduce are reliable enough.
"Every department of the racing operation is working flat out," he added. "There are a lot of new parts that we will introduce gradually, from aerodynamic changes to mechanic changes. It is on every single item of the car, that there will be some development coming. Everyone else is also doing this at the moment, so we will have to wait for an answer about who is developing the fastest."
