The IndyCar Series leads all other forms of sport in the U.S. in terms of growth, increasing its fan base by 9% yearly since 2004. Compared to NASCAR, a sponsor can find a better dollar-per-fan ratio in the IndyCar Series.
Sponsors who remain in NASCAR can take advantage of “cross-marketing” between the two series. Race fans show an extraordinarily high percentage of sponsor product loyalty realized by those brands affiliated with motorsports. The Indianapolis 500 Mile Race, IndyCar Series anchor race, remains the "Greatest Spectacle In Racing" boasting a larger attendance than any other race in any series and even larger than the Super Bowl.
The IndyCar Series has momentum! With the recent merger between the IndyCar Series and the Champ Car Series, there is a heightened interest in the IndyCar Series. The Series has become more competitive and offers some of racing’s hottest new media stars. New young driving stars are quickly adding a younger demographic. Not only is this younger demographic important to sponsors, it helps ensure the longevity of the sport.
