Chip Ganassi Racing was on its way to reclaiming the 24 Hours of Daytona title, with Juan Pablo Montoya leading more than six hours into the sports car endurance race Saturday. Montoya powered past Lucas Luhr on the outside of the slippery track after a restart on the 169th lap. He deftly guided the No. 02 BMW Riley with clean and crisp moves on Daytona International Speedway's infield twists that had been pelted with rain early, causing cautions and skid outs. Montoya's teammates and fellow Indianapolis 500 champions Dario Franchitti and Scott Dixon held the top spot for a combined 91 laps when he regained the top spot. They considered the early lead a big accomplishment under the conditions. There were nine other cars on the lead lap. Alex Gurney was in second when he handed off to teammate and four-time NASCAR champion Jimmie Johnson for Gainsco/Bob Stallings Racing after about three hours. Johnson kept them in contention, and Jimmy Vasser pushed them in the lead for three laps before pitting. Vasser was in seventh after six hours.
