DAYTONA BEACH, Fla. (AP) - Engine problems gave the 24 Hours of Daytona a twist Sunday, with the Chip Ganassi Racing car that dominated the first day falling out. The organization's second entry was one of two cars on the lead lap more than 18 hours into the sports car endurance race.
Scott Pruett was guiding Ganassi's No. 01 BMW Riley about 10 seconds behind Mike Rockenfeller of Action Express Racing. Some of the biggest names were far out of contention come sunrise.
The most startling development came shortly after midnight, when Ganassi's No. 02 car had a piston failure in the engine. Drivers Juan Pablo Montoya, Dario Franchitti, Scott Dixon and Jamie McMurray had led a combined 132 of the opening 247 laps.
Then suddenly, stunningly, they were out.
