The GF09's last appearance was in practice for the 2008 Indianapolis 500 when Phil Giebler, who drove for American Dream Motorsports, crashed his Panoz chassis and failed to qualify. Panoz effectively discontinued their IndyCar Series involvement after the 2008 season due to all IndyCar Series teams opting for the Dallara IR-05 chassis, and Panoz concentrated on sports car endurance racing.
