The German looks to have broken Mercedes' stranglehold on the F1 title and, having trailed in their wake for three years, is 14 points clear of Lewis Hamilton.
The 30-year-old has won four Grands Prix wins this year, in Australia, Bahrain, Monaco and Hungary, and is eyeing a fifth drivers' title.
It always seemed as though Ferrari, and in particular Vettel, would challenge Mercedes this year and the former Red Bull flyer seems more than content with his showing so far.
"It's what I dream about, to be honest," he said. "I want to win, so that's where you want to be. I don't have very precise dreams in terms of gaps, points and stuff like that.
"I think all in all, the mission has been to get back to the top, so obviously we had a great year, I'm only two-and-a-half years in with the team.
"I think we had a great year in 2015, which helped to get the project going."
