Hour 2 of the Rolex 24 at Daytona saw some of the high-profile teams that had been confined to the garage resume racing, or still carry out repairs flat-out to resume their progress. Scott Pruett carried on leading in the #01 Chip Ganassi Racing with Felix Sabates, with the #02 of Scott Dixon closing the gap incredibly quickly, before Max Angelelli capitalized on a slow stop from Dixon, and was just over 2 seconds behind the 4-time winner as the sunlight started to fall at the end of the hour. Dario Franchitti was later robbed of further places, as the restart was feverish with Prototypes swarming three wide into turn 1.
The #43 Team Sahlen had power steering and gearbox issues, after having an excursion off track at Turns 5 and 6, with the #3 8 Star Motorsports Corvette finally coming back on track after repairs finally were carried out and found itself last in class. A.J. Allmendinger in the Michael Shanks Racing Ford-Riley pushing hard to make up for lost time, closing up by a further 3 laps in the second hour. The #50 Highway to Help Riley was finally back on track after a gear cluster replacement kept them in the garage.
The GT Class saw Olivier Beretta in the #63 Scuderia Corse Michelotto Ferrari leading at the end of the second hour, as Andy Lally in the Magnus Racing Porsche handed over the lead as the round of pit stops, as well as AIM Autosport Team FXDD’s Ferrari moving into second place in class. Stevenson Motorsports’ #57 Camaro was now in the top 3, with only one Audi in the top five.
The GX Class saw absolute disaster for all three Mazda 6s, all running the Sky Activ Diesel power plants, as the #00 Mazda again slowed on the racing line, with smoke billowing from the rear, showing signs of fragility, and brought out the first full course caution of the race. Then the other two cars were pushing back behind the wall, as there were further concerns, as the gauges were functioning, but their problems were even greater. It was a Porsche 1-2-3 in the class battle, as the #16 Napelton Racing Porsche was still ahead, as all teams were heading into dusk.
