Jarno Trulli hopes that an updated power steering system planned for the Hungarian Grand Prix can help rescue his season with Team Lotus.
The Italian has struggled all year to get comfortable with his feeling in the car, and an ongoing lack of confidence in the power steering design has left Trulli unable to push it to its limits.
The Hingham-based outfit has made several modifications to the system to try and help Trulli but, having failed to overcome all his problems, another new version will be tried out at Budapest.
Speaking to AUTOSPORT about the ongoing power steering issues, Trulli said: "I hope that in Hungary we should have a new power steering. So this I hope will also help my feeling with the car."
Trulli says that the power steering problems are preventing him making much progress with the car at all, because he cannot feel what set-up changes need to be made.
"I said straight away that I cannot really set up the car or judge the car," he said. "So if someone asked me what's going on in the car I always say I don't know - I'm just trying to drive what I have but I cannot give any feedback to the team. It's a bit frustrating but that's the way it is at the moment.
"It is quite a complicated thing. Basically the power steering has got some anomalies and gives some wrong feelings, and something is happening there. So because I am so precise, at the beginning of the season I was really struggling with that.
"Because basically when you are in the corner, at a certain steering angle you keep feeling [shakes his hands to indicate steering shake] and so I react to this. But actually I am reacting to something which is not correct."
Although Trulli's struggles this season have cast doubt over his future in F1, he is adamant that his major concern is getting the car sorted now rather than worrying about what he does next year.
"I don't really care about this," he said. "What I do care is that I have struggled sometimes to enjoy what I am doing, more than thinking about the future. The future we will see, the team knows what I am going through. They know why sometimes I am quick and sometimes I am not. But to be honest I don't really care about this."
