The 1993 PPG Indy Car World Series season was the 15th national championship season of American open wheel racing sanctioned by CART (d.b.a "IndyCar"). The season consisted of 16 races. Nigel Mansell was the national champion as well as the Rookie of the Year. The 1993 Indianapolis 500 was sanctioned by USAC, but counted towards the CART points championship. Emerson Fittipaldi won the Indy 500, his second career victory in that event.
