As is often the way with endurance racing, the 60th running of the Rolex 24 at Daytona turned into a sprint for the flag after a safety car intervened with less than an hour left on the clock. The Rolex 24 was the final Daytona 24-hour race for the DPi category of prototypes, and the class put on a fine show over the weekend.
There were dozens of lead changes over the course of 24 hours, and any of the five Cadillac DPi-V.Rs and two Acura ARX-05s would have been plausible winners. But racing for 24 hours is not easy, and hour 13 took out two of the contenders: the No. 48 Action Express Racing Cadillac (which counted NASCAR legend Jimmie Johnson as one of its drivers) and the 301 Chip Ganassi Racing Cadillac (driven at the time by multiple-IndyCar champion Sebastien Bordais).
With less than eight hours remaining in the race, the second Chip Ganassi Cadillac had to spend time in the garage with a fuel pump problem. That left a four-way fight for the win between a pair of Cadillacs (the No. 5 JDC-Miller Motorsports car and No. 31 Action Express car) plus the pair of Acuras (the No. 10 Wayne Taylor Racing car and the No. 60 Meyer Shank Racing machine).
