Cape Town - Sebastian Vettel joked the 2018 season could be a "walk in the park" for Ferrari if they make the same step in progression like they did in 2017.
Sitting alongside Lewis Hamilton and Daniel Ricciardo in the final drivers' press conference of the season in Abu Dhabi, Vettel was asked whether Ferrari had learned and improved enough to launch a sustained title challenge in 2018.
"Well I think if we can do a similar step for next year
and... don't get me wrong, it's a joke and Germans don't like to joke so
much, it should be a walk in the park," he replied.
"What I want to say by that is the steps made this year have been incredible. The way the team came out with a competitive car at the beginning, the way we have improved both chassis, engine has been outstanding.
"It has been close for most of the year but not close enough when it mattered. From that, we have made our conclusions, learned our lessons so that will help us next year.
"We are completely fired up. It has been bitter but I think it has been positive that we have had a couple of races (this year) to approach and look forward to next season."
