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.
*Terry Labonte would decide to withdraw from the race, as he was still angry at NASCAR's actions at the 2004 Budweiser Shootout. Labonte had stated that NASCAR said that cars were not allowed to pit, but near the end of the race, cars were allowed to pit. Labonte would not pit and finish eighth. According to Labonte, "What happened last year is the reason I'm not in it this year."[2]
