Sebastian Vettel is confident Ferrari can finish 2016 on a high after his drive from last to fifth at the Singapore Grand Prix, something he thinks highlighted the strengths of the team's package.

Singapore was another disappointing weekend for Ferrari, with a suspension issue in qualifying dashing Vettel's hopes of challenging for a win or podium. Teammate Kimi Raikkonen finished off the podium despite running third ahead of Lewis Hamilton before a questionable strategy call late on.

Despite the negatives from Singapore Vettel thinks his performance in Singapore should give the team encouragement.

"I think if we get everything right then we know we have a strong package, for sure," Vettel said. "There have been a lot of races where we didn't do that; some was up to us, some was up to stuff that happened, but for sure it didn't end up so far the way we wanted and we're not yet where we want to be. But I think we believe in ourselves."

Ferrari is only 15 points behind Red Bull in the fight for second and Vettel thinks planned upgrades will help cut the gap in the remaining six races.

"For sure we are not entirely where we want to be in terms of raw pace. Sometimes it's a bit better, sometimes it's worse. Obviously on tracks like this it's generally more close so we kind of expected to be competitive and then you always have a chance to win or fight for a very solid podium.

"Unfortunately it didn't turn out for both of us but I think going forward we have confidence, there are some bits coming still. We're here to fight and that's what we're going to do."
