Things haven't always gone according to plan for Kimi Raikkonen and Lotus during pre-season, but the Finn says it is nothing to be concerned about.
After sitting out day three in Barcelona on Saturday due to health problems, Raikkonen was forced to spend a lot of time in the team garage on the fourth and final day after a gearbox change.
He completed only 50 laps on Sunday, but is nevertheless confident they will fix the problems before the season gets underway.
"For sure this winter could have run a bit smoother for us and there have been a few problems here and there, but this is pretty normal and whenever we've been out on track the car has felt good," he said.
"The issues we've had have been pretty minor and we've found solutions to all of them, but unfortunately they took a bit of time to fix so in the end it's cost us track time which is a shame. If you look back at last year the car was very reliable, so hopefully it will be the same again this season; I'm not worried about it."
The usual suspects - Ferrari, McLaren, Mercedes and Red Bull - are once again expected to challenge for honours in Melbourne, but the 2007 World Champion says it's too difficult to predict who will come away with the win.
"It's hard to say as you never know what kind of programme the others are running," he said.
"We've run through a lot of assessments over the past few weeks and the feeling in the team is that we have a strong basis to start the season, even if we haven't shown that every day.
"I'm happy with the car and looking forward to going racing. Whether we'll be up there from the start we won't know until we get there, but we don't have to wait very long to find out."
