Force India are coming to the British Grand Prix armed with their biggest update of the season so far.
Fourth-placed Force India are 49 points ahead of their nearest rivals Williams in the World Constructors' standings. But the midfield battle is far from over yet, especially given Haas' sudden improvement last weekend in Austria.
Force India, though, are hoping they are in a position to take step up at Silverstone in order to keep themselves ahead of the rest.
"We've got a suite of things coming for Silverstone, including a new front wing," said technical director Andrew Green. "There are other bits as well, mainly the front end.
"It's one of our biggest if not the biggest we have done so far this season."
Green was also asked whether it was a bigger upgrade than the one introduced in Spain: "Yes. It'll be incremental from there and then there will be another big update around Singapore time.
"That is just coming through the wind tunnel now, it's going into full-size now."
Green also revealed that it is not yet clear when the Force India team will start prioritising work on next year's car.
"It's going to start to become a challenge when we have to allocate resource to next year's car," Green added.
"The two cars, this year's and next, are aligned. From a concept perspective, everything we learn on this car transfers straight to next year's car.
"In that respect, we'll keep on bringing parts to the track. They will become less frequent and less complex parts but we will be bringing parts.
"A lot will be looking over our shoulder and seeing how far away fifth place is and whether we can focus more on next year."
