The 1985 CART PPG Indy Car World Series season was the 7th national championship season of American open wheel racing sanctioned by CART. The season consisted of 15 races. Al Unser Sr. was the national champion, and the rookie of the year was Arie Luyendyk. The 1985 Indianapolis 500 was sanctioned by USAC, but counted towards the CART points championship. Danny Sullivan won the Indy 500, in dramatic fashion, a race that became known as the "Spin and Win."
