Raikkonen is optimistic Lotus has hit a sweet spot in setting up the E20 and believes that if the Hungarian Grand Prix remains dry he may finally be able to fully deliver on the E20's promise this weekend.
The Finn, who has finished on the podium four times in the ten races he's started since returning to the sport in 2012, still thinks a win is possible this year if the team can get a clean race and the conditions are right.
"We haven't won any races so it [the car] is not a winner," he said at Hungary. "We have a good package but for many reasons we haven't got the best out of it, or not got the best out of it in all the races. We are still pretty happy but you want to do better, we want to win races, but it hasn't happened so far but hopefully we can.
"It is not easy, we know that, and we keep trying to improve things from the things we do, and we see what we can do in the second part."
Raikkonen added that rain in the build-up to the race in Hockenheim last weekend cost the team badly in the German Grand Prix. It meant that Raikkonen could finish than fourth on the road after qualifying 10th.
"We had good speed in the last weekend, apart from the rain where we could not get anything for some reason," he said, "and that really put us in a not very good position. But I think if I is a dry weekend we have found the place where we want to be with set-up and things like that, so hopefully we can be better than last weekend."
