World Wide Technology Raceway just outside of St. Louis, Missouri is an intriguing 1.25-mile (2.01 km) oval favored by many of the drivers who race there due to the unique shape and varying degrees of banking in each corner. Turns 1 & 2 have characteristics similar to New Hampshire Motor Speedway while Turns 3 & 4 are similar to ISM Raceway in Phoenix and the track's egg shape is reminiscent of the oval at Twin Ring Motegi.

The 2.439-mile, 14-turn road course incorporates portions of Turns 1 and 2 and the front straight of the famed Indianapolis Motor Speedway oval and the remainder of the circuit is within the infield, allowing for great spectator viewing.
