Sauber will introduce a significant upgrade to its car at the Spanish Grand Prix, which technical director James Key believes will shave off several tenths of a second in lap time.

The updates will affect several areas of the car, including ongoing work on the team's latest iteration of the blown diffuser.

"We'll have a new, quite significant aero package on the car, which will be a completely new front wing, updates to the front and rear brake ducts, new bodywork, new devices around the floor leading edge and under the chassis, and we'll be testing the new exhaust system again," Key said.

"We'll also be continuing our work on the mechanical update we had in Istanbul, which proved to be positive. So it will be interesting to see how this works. If it works well it should give us a good few tenths of a second improvement in lap time. Our goal is to continue our good race form, to try to improve qualifying and finish as high in the points as possible."

Sergio Perez is hoping the upgrades will help deliver the first points of his debut season after collisions at the last two races cost him dear.

"I'm looking forward to the weekend in Barcelona very much," Perez said. "I have been quite unlucky in the previous races and I really have the feeling the Spanish Grand Prix is when this will change. I strongly believe I will score points there.

"I am very motivated and I like the Barcelona circuit a lot. Also I always did well there. In Turkey we weren't able to show our potential and I hope this changes in Spain and, to begin with, we are better in qualifying. We will bring an update for the car and I trust it will meet our expectations."
