Kimi Raikkonen reckons Lotus will be quick in Saturday's Spanish qualifying, after all "we've been fast everywhere else so far."
The Finn, who finished runner-up at the previous grand prix in Bahrain, was fifth quickest in Friday's practice with a 1:23.918.
That time was set using a different front wing to the one previously run by Lotus.
But how much of a difference it made Raikkonen isn't willing to guess.
"There were no problems with the car and everything felt good today," said the 32-year-old.
"We tried a different front wing, but in the car you can't tell if it makes much difference; that is why the team's engineers are looking at the data.
"I felt comfortable and I think the work done at Mugello and in the Windshear test programme have made improvements."
The 2007 World Champ added that his feeling positive about his chances in Saturday's qualifying and sees no reason why Lotus cannot take the fight to the frontrunners.
"We'll have to see tomorrow how much pace everyone has when it comes to qualifying as that's when it matters.
"We've been fast everywhere else so far and there's nothing to suggest we won't be fast here again."
