Kimi Raikkonen says Ferrari has "quite a bit of work" to do on reliability after suffering two retirements during the opening rounds of the 2016 F1 season.
The Finnish driver was forced out of the first race in Australia after a turbo issue, which caused a fire in the airbox of his Ferrari SF16-H.
Meanwhile team-mate Sebastian Vettel failed to start the last race in Bahrain due to a valve failure. The German driver finished third at the season opener, while Raikkonen finished second in Sakhir.
Raikkonen is pleased with the speed of the car but admits the Maranello-based outfit still has lots to improve on in terms of reliability.
“We’re still positive about what the team has built over winter, that hasn’t changed at all,” he said in Thursday’s FIA press conference.
“Obviously it hasn’t been ideal, the first two races, for us as a team. We had two podiums but two not scored, not finished. That’s not what we want. There is quite a bit of work to be done on that side – but the speed is there.
“Not in qualifying exactly – if you take the last qualifying in the last race. Until that it was pretty OK. I think we have a good package, we just have to improve it and make it even better but, the car has improved in all areas: it’s not just one thing that has improved over the winter.
“Still not as good as we want to be, not the best that we wanted to be – but this is definitely a good car and we go from there. But there’s always things to improve and do things better.”
