"It is still taking a little time to sink in what I've achieved this week as was the case when I won the FedEx Cup but then it just kept getting better and better as the days went on and I am sure this will be the same," he said.
Stenson was consistent throughout the season but produced his best form at the final tournament, where he outclassed his nearest rivals with some excellent play.
He becomes the second Swede to end the season as Europe's top player — replicating the success of Robert Karlsson in 2008.
Stenson said the victory capped off what had been a "dream season", adding that he was at a loss in terms of how he would better it.
"I played so well this week. I knew the guys would try to catch me, especially Ian (Poulter) who never gives up. I wanted to stay ahead of him and I managed to do that," he told the European Tour website.
"I don't know how I am going to be able to top this next year but I am going to give my best in the Majors and that (to win one) would be the icing on the cake."
