Rosberg announced the surprising news Friday at the FIA gala in Vienna, five days after he won his first world title in F1.
"Since I started racing 25 years ago, it was my dream, my one thing, to become a world champion in Formula 1", says Rosberg in a statement. "And now, after all the hard work, the pain and the sacrifices, it has paid off."
"I stand on the top of the mountain, so this feels good. My strongest emotion right now is the gratitude for everybody who made it possible to make my dream come true."
I think we will never know the true reason Rosberg quit F1. Or maybe we will, if Rosberg decides to publish a biography, like Lewis said he will after he quits F1, and writes the real reasons down.
