Kimi Raikkonen is confident that Ferrari's difficult showing at the British Grand Prix is circuit-specific, rather than a deeper malaise with the SF16-H.
Raikkonen qualified in fifth place and raced to the same position, albeit over a minute adrift of Mercedes' Lewis Hamilton, who claimed the squad's ninth victory of the campaign.
With Red Bull finishing third and fourth courtesy of Max Verstappen and Daniel Ricciardo, it means Ferrari holds a slender nine point advantage over its rivals in the scrap for second in the standings.
"The whole weekend has been difficult," Raikkonen said.
"We're missing downforce and, at a place like this, it's not easy. You need downforce here to go fast. With the mixed conditions, the wind, you take a big penalty on that.
"I'm sure the next circuits will be much more normal for us. Downforce will help in any place, it doesn't matter where we go, so it's what we need to challenge [Mercedes] at every circuit.
"I'm sure if we would put downforce like a few cars in front of us it would be a completely different story. I think right now, in these kind of conditions, and circuit, that's our biggest issue."
Team-mate Sebastian Vettel slumped to a low-key ninth in the other Ferrari.
