In 1982, Rahal entered the CART series with the Truesports team, winning two races and finishing second in the championship behind Rick Mears. He continued racing for Truesports through the 1988 season, winning at least one race every year. In 1986, Rahal dramatically passed Kevin Cogan on a restart with two laps to go to win the Indianapolis 500, only days before his team owner, Jim Trueman died of cancer. Later that year, Rahal won his first CART championship, and successfully defended it the following year.
