For the 2004 IRL season Panoz introduced GF09B, the updated version of the 2003 model GF09. While majority of the 2004 IRL teams used Dallara chassis, few others, including Chip Ganassi Racing opted for G-Force, whose cars were present in the league since 1997. 2003 series champion, New Zealander Scott Dixon did not defend his title. In the 32 races held during these two years, Dixon made the podium only once, finishing second at Phoenix International Raceway. The weak element in the chassis-engine combination was Toyota engine, which could not be as competitive as Honda counterparts.
