TNT analyst Kyle Petty called the wreck "the official first fireworks of the Fourth of July," since the incident occurred just after midnight.
David Stremme's spin through Turn 3 on Lap 136 provided an opportunity for pit stops with 23 laps left in the race. Kurt Busch won the race off pit road, but the field couldn't complete a full lap before a crash involving Matt Kenseth and Elliott Sadler slowed the field for the fifth time.
That was just an appetizer, however, for the wild melee that followed on Lap 148.
David Ragan turned sideways in Turn 3 and triggered a Lap 117 wreck that demolished the car of Daytona 500 winner Jamie McMurray and damaged the vehicles of Martin Truex Jr. and Kahne, who slid in oil and hit the wall behind the collision. The wreck knocked Truex out of the race, but Kahne recovered to run in the top 10 before finishing second.
"You had to be aggressive and drive your car sideways all night long," Kahne said. "That's just the way it was. I felt like I had one of the best cars from start to finish -- even hitting the wall I still felt like we had a great car. It was just a wild race. I really enjoyed it."
After climbing to second in the Cup standings, Kyle Busch had his third consecutive star-crossed run. Contact with Montoya's Chevrolet on Lap 104 sent Busch's No. 18 Toyota -- leading the race at the time -- nose-first into the backstretch wall. Busch finished 40th.
The 18 different leaders Saturday night were a record for the event.
