The cars ran with the spoiler on the rear of the cars, as NASCAR announced in January that it was going to transition from the wing to the traditional spoiler sometime during the first quarter of this season. Teams started the day with a 1 1/32-inch sized restrictor plate. For the majority of the morning session, the teams participated in single-car runs over the 2.66-mile superspeedway. However, five cars hooked up for some drafting shortly before the lunch break and the speeds picked up a bit, with Jimmie Johnson (No. 48 Lowe’s Chevrolet) putting up the quickest time of 48.741 seconds or 196.467 miles per hour.
