After once again falling foul of minor problems, Kimi Raikkonen is hopeful of putting in a full race distance on his final day of testing.
The Ferrari driver will return to the cockpit on Saturday having handed the F14T over to Fernando Alonso for Day Two of the Bahrain test.
The day will be an important one for Raikkonen, as it will be his final opportunity in the car before heading to Australia for the season-opening grand prix.
Raikkonen hopes to spend it making up for the track time he lost on Thursday where once again he was hit with minor issues.
The Finn, who won the 2007 World Championship with Ferrari, managed just 54 laps with a best time of 1:36.432, which put him third on the day's timesheets.
"I've seen much worse winters [of testing] than this one so I'm not worried about it, we would like to keep putting more mileage on the car," he told ESPNF1.
"We've learnt again and we will see where we are on the last day.
"There were small changes we had to make but they all take time. There's been no major issues, from team to team it has been difficult to get a good feeling on certain things with set up but we are getting there little by little.
"We need to do a little more laps of course but that's how it is. I think we need to do a race distance on the last day, and then see how we are."
He added: "I think there's been a lot [of improvement] in driveability but there is always places to improve and that's what we are looking for really. It's more to get the car how I like it to be but it's difficult to know or find the right levels.
"The car looks reliable, we have some small issues but everyone has. I think we improve all the time, finding new things and learning more. It's hard to say from day to day, things change always. I'm sure we learned again."
Raikkonen, though, would not be drawn on Formula One's pecking order, yet again insisting that it is too early to judge.
"The feeling is okay but lap times will decide where we are and we will see in the first race where we sit. I don't know [who are favourites]. We will see in Australia who is the best.
"My target is to try to win but right now I don't know where we are.
"It's going to be a long season with the new rules for everyone. It gets exciting when we get to racing again. There's lots of things we are still trying to learn and they will get better. It's all new stuff and hopefully we can do a good final day."
