Although Charles Leclerc says Sauber are racing “above expectations”, he reckons there is even more to come from the Formula 1 team.
Last season, racing a year-old Ferrari engine, Sauber managed just five points the entire campaign.
“We all are aware it’s above our expectations and we need to keep on the ground and keep working,” said Leclerc.
“But, yes, definitely [Sauber can aim higher].
“We really thought it would have been a big problem for us this weekend and it definitely has not been the case. We are now a bit more comfortable.”
The Sauber rookie was racing his way toward a sixth top-ten result at Silverstone when he was forced to retire due to a loose wheel after a pit stop.
He added: “I keep thinking that in terms of pure potential we are still a bit behind, but we are very good at hitting the right balance in the car that makes the car easy to drive and that’s why we manage to get this performance.
“If the others keep struggling to put their car in the right balance then it might be better for us because we might achieve this, but once they get their car in the right balance we might struggle more.
“Teams have struggled with the warmer conditions here, and we have maybe struggled a bit less, so maybe it’s a combination of things that make us particularly strong this weekend.
“But we need to keep our feet on the ground, keep working because it’s not going to be Q3 every weekend. We will try to push. Hockenheim is a track I really like so hopefully it can be as good a weekend as here.”
