Kimi Raikkonen is adamant Lotus have what it takes to be the team to end Red Bull's reign this season.
The Finn returned to Formula One last season with Lotus and tasted success when he took the chequered flag at the Abu Dhabi Grand Prix.
It was a strong finish to the Championship, which saw Raikkonen finish all but one of the 20 grands prix in the points. His points-scoring run put him third in the standings.
Raikkonen is keen to build on that in his second season with Lotus and says there is no reason why the team cannot be the ones to end Red Bull's three-year run.
"It's clear from working with them that they are racers, and you can see in their history that they've won Championships," he said. "Nothing I saw last year made me think that another Championship was impossible in the future.
"Of course, there is some pretty tough competition out there and everyone wants to win. The team have beaten everyone before and there's nothing to say they can't do it again."
The Finn highlighted one area in which Lotus need to up their game but concedes it is the complete package that must be quicker.
"We've tried to improve on all areas and for sure if we qualify higher up then it will help us win more races but it's the whole package which we want to be faster and hopefully we have done that."
