DAYTONA BEACH, Fla. — Joao Barbosa has powered Action Express Racing to the 24 Hours of Daytona title with an improbable victory in the organization's first appearance in the sports car endurance race.

The newly formed team avoided major mechanical problems and benefited from a late blunder by star-studded Chip Ganassi Racing to win by 50 seconds Sunday. Ganassi's Justin Wilson was leading before he made an ill-advised stop into the garage late, believing something was wrong with the No. 01 BMW Riley.

The crew didn't find anything, and the difference was too much for teammate Scott Pruett to make up in the final two hours. The group that has dominated the race recently could only watch as it lost to a team with few sponsors that, weeks ago, didn't exist.
