Adrian Sutil does not expect a big change in Formula 1's pecking order at the Spanish Grand Prix, even though most teams are expected to bring a raft of updates to their cars.
With teams having saved their first big car upgrades until the Barcelona event, seven outfits believe that improvements could lift them nearer the front of the field. But Sutil is less convinced about any team being able to do that – because he thinks most cars are already at their maximum limit in terms of potential.
"We've got a few bits, but the car will be very good there [at Barcelona] I think, and the top 10 will be very similar to what we've seen in the last few races," Sutil told the Force India website.
"Nobody will be finding half a second in their car, because right now it's really hard to improve the cars. Everybody is at a point where it's hard to find every single tenth."
Sutil believes that the high-downforce demands of Barcelona will almost certainly play into the hands of Red Bull – which has had the out-and-out quickest car at the start of the campaign.
"There you just need downforce, so I think it's a Red Bull circuit again," he said. "You have a long straight, but if you have a quick car through the corners, it's definitely a better way."
