Jamie McMurray, last year¿s surprise winner of the UAW-GM Quality 500, led the speed parade Tuesday night at Lowe¿s Motor Speedway as seven NASCAR Winston Cup drivers and teams fine tuned their ¿night moves¿ in preparation for the inaugural nighttime running of the track¿s 500-mile fall classic.

The unofficial stopwatches caught McMurray¿s No. 42 Havoline Dodge with a lap of 29.834 seconds (181.002 mph) around the 1.5-mile superspeedway. McMurray¿s pacesetting lap was posted after the sun had set and the track surface cooled, nearly identical conditions teams will face during Bojangles¿ Pole Night qualifying on Thursday, Oct. 9.

Interestingly, McMurray¿s lap came in a different car than the one he drove to victory last year. That No. 40 Dodge is still part of the stable of cars being wheeled by McMurray¿s teammate, Sterling Marlin.

Dale Jarrett, a two-time UAW-GM Quality 500 winner, was second fastest on the unofficial watches at 180.566 mph in the No. 88 UPS Ford.

Jeff Fultz, the May 2002 winner of the EasyCare Vehicle Service Contracts 100 ARCA race, was third fastest at 180.391 mph in the No. 55 Ford. NASCAR Busch Series point leader Scott Riggs, making his first appearance in the No. 57 Ford, was fourth fastest at 179.509 mph while Scott Wimmer rounded out the top five at 177.954 in the No. 27 Chevrolet

A brief rain shower shortly before 5 p.m. forced officials to stop the session for just over an hour. The only on-track incident came when Christian Fittipaldi¿s No. 44 Dodge scraped the outside wall in turn four.

Testing for the UAW-GM Quality 500 continues Wednesday. NASCAR Winston Cup cars will be on the track from 3 p.m. to 10 p.m. and spectators will be admitted free to the main grandstand.

Tickets for the UAW-GM Quality 500 on Saturday night, Oct. 11, start at just $19 and can be purchased online at www.charlottemotorspeedway.com or by calling 1-800-455-FANS.
