CONCORD, N.C. -- Kasey Kahne, who only qualified after being voted in by the fans, used a late pit gamble and bad luck by another competitor to win Saturday night's All-Star Race and more than $1 million.

Kahne finished fifth in the Sprint Showdown -- the prelude to the all-star race -- and won the fan vote to start last in the 24-car field.

He benefited because Joe Gibbs Racing saw two of its cars have engine problems while leading.

Kahne took the lead when Denny Hamlin's engine soured as he led on lap 83 in the 100-lap race and held on the rest of the way.

Greg Biffle finished second with Matt Kenseth, Jimmie Johnson and Tony Stewart completing the top five. Dale Jarrett, running in his final Cup race, finished 21st.

Kahne had not challenged for the lead until he moved toward the front during a pit stop before the final segment. He and Johnson were the only drivers not to take tires. Johnson restarted first with Kahne second. Hamlin was third with Biffle fourth going into the final 25 laps.

Biffle, who had one of the fastest cars, could never get by.

"I can't believe I got beat by no tires considering I put two on,'' Biffle said afterward.

At least he was there at the finish. Both Kyle Busch and Hamlin had engine problems while leading and neither finished.

Busch, Hamlin and Stewart each had experimental engines this weekend. Stewart had to change engines Friday and then came Busch's problems after he led the first 38 laps.

Gibbs was using its own engines this weekend. The team has used engines from Toyota Racing Development all season while developing its own Toyota powerplants and used this event to test the engine's progress.

Hamlin radioed his crew while leading on lap 83

"We're done,'' Hamlin radioed as his engine suffered problems.

"Great job man,'' Hamlin radioed his crew. "You gave me a fighting chance. They were going to have to knock me out to do it.''

Their problems were about as exciting as it got. The race was devoid of fireworks -- except for those during pre-race introductions and after the race. There was not a caution except for the breaks between the 25-lap segments.

Kyle Busch led the first 38 laps before a broken rocker arm slowed him. He made it to the halftime break after 50 laps but his crew could not repair his engine woes and he finished.

As the cars restarted to run the final 50 laps, Busch walked to the garage and his crew pushed the car away. The crowd, which had booed Busch when he and his crew did a bow during pre-race introductions, saluted the stricken car by cheering its demise.
