Sergio Perez believes he can achieve his third podium result of the season in Britain but will need a boost in qualifying.
Sauber are heading to the Silverstone circuit with an updated package for their C31 which includes modifications of the engine cover and the rear of the car.
Perez, who is ninth in the Drivers' Championship on 39 points, is hoping to put those upgrades to good use as he seeks his third top-three result of the campaign.
"I think our car will be good in Silverstone and I want to fight for another podium there," Perez said.
"In my view in Silverstone it is even more difficult to overtake than it was in Valencia, therefore qualifying is high priority on the job list. I need a better grid position than recently.
"I like the fast and fluid corners a lot, so this is a very enjoyable part of the track.
"The race in Silverstone is a special grand prix - because of the fans and the atmosphere and also for me personally. I lived in Oxford for three years and I have quite a few friends in England."
The Sauber driver also knows what it is like to win at Silverstone, having taken victories there in both Formula 3 and the GP2 series.
"I really like the Silverstone circuit. I have won there in Formula 3 and in GP2 and also last year my first Formula One race was good," he said.
"I came seventh and this was actually my best race result in 2011. Back then it was a crazy race in difficult weather conditions with the track drying."
