Format and eligibility

The race was broken up into two segments: a 20-lap segment, followed by a ten-minute intermission, concluding with a 50-lap second segment. While a pit stop was no longer required by rule, a reduction in fuel cell size (from 22 gallons to 13.5 gallons) made a fuel stop necessary. (In 2007, fuel cells were expanded to 18.5 gallons.) Many drivers also changed two tires during their fuel stop, as the time required to fuel the car allowed for a two-tire change without additional delay.

Pole winners of the previous season were automatically eligible for the race. Then, previous winners who had not already qualified would receive automatic berths.
