British rookie Mark Taylor won the series with a total of 7 wins in 12 races, driving for a newly formed program by IndyCar team Panther Racing, who then signed him to drive for the team's main programme in 2004.

Ed Carpenter, driving for reining champions A. J. Foyt Enterprises, won the race over Cory Witherill from pole position, his lone win of the year in route to a 3rd place finish in the standings.

Thiago Medeiros won the final race at Texas and finished a mere six points behind Carpenter.

Aaron Fike was also a winner at Pikes Peak, but he missed the Phoenix race early in the season for a DUI offence and didn't score another podium during the year, losing fifth place in the points to Witherill.

Among former IndyCar competitors Witherill and Brandon Erwin competed full-time in the series, while Billy Roe, Scott Harrington and Ronnie Johncox also took part in the Freedom 100, and Dave Steele in the Nashville race.
