For the 2008 season, Wheldon stayed with CGR. He began the year finishing third at the season-opening Gainsco Auto Insurance Indy 300 at Homestead–Miami Speedway after moving through the field starting from 22nd. Wheldon won the RoadRunner Turbo Indy 300 at Kansas Speedway three races later, becoming IndyCar's first driver to claim two consecutive victories at the track. He started eighteenth in the Indianapolis 500 finishing six places higher in twelfth due to handling problems in the final 50 laps. Wheldon took his second (and final) victory of the season in the Iowa Corn Indy 250 at Iowa Speedway. He donated his winnings to help the victims of the recent tornadoes and flooding which had occurred in Iowa. As IndyCar had become more orientated towards road and street circuits, his performance diminished in the remaining races. He achieved one further podium finish, a second-place at Nashville Speedway, and five top-seven finishes for fourth in the drivers' championship with 492 points.
