Cheever lost its Red Bull sponsorship after the season and Carpentier was left without a ride as the now unsponsored team scaled back its IndyCar involvement dramatically, although he did race for Cheever in the 2006 Rolex 24 at Daytona, driving a Crawford-Lexus DP03.
Carpentier competed in the 2006 CASCAR Super Series event at Cayuga Speedway.
