·      Tom Long made history at the end of his opening stint early in the race when he took the lead in the No. 07 SpeedSource Mazda SKYACTIV-D Smart Diesel, becoming the first diesel-powered car to lead overall in the Rolex 24. It also was the first time Mazda has led the Rolex 24 overall, although the manufacturer has 22 class victories in the event, second behind only Porsche (68).

·      Two drivers in search of career milestones are in good position at the one-quarter mark. Scott Pruett – looking to win a record sixth Rolex 24 overall – leads in the Prototype class while teammate Jamie McMurray is second as he tries to join A.J. Foyt and Mario Andretti as the only drivers to win both the Daytona 500 and Rolex 24.

·      The No. 912 Porsche North America Porsche 911 RSR, in a quest to defend its inaugural Patrón Endurance Cup championship in GTLM, fell victim to a gearbox issue three minutes into the 24-hour race, losing six laps. The car has since run flawlessly and now sits four laps down in ninth.

·      Attrition was one of the main storylines in the opening six hours of the event with a number of competitive cars running into early trouble. Among those, the No. 97 BMW Z4 of defending TUDOR Championship GTD champion Turner Motorsport suffered a pair of gearbox related issues relegating the team to 97 laps down in class at the six-hour mark. The No. 0 DeltaWing Racing Cars DWC-13 – which ran solidly in the top-five for much of the early part of the race put fell victim to a transmission issue – and the No. 2 Tequila Patrón ESM Honda HPD ARX (systems failure) were forced to retire. Also retiring right before the six-hour mark was the No. 57 Krohn Racing Ligier JS P2/Judd which reportedly suffered an engine problem.

·      One year after nearly sweeping the four Patrón Endurance Cup events, CORE autosport is off to a strong start in a quest to return to victory lane in the Rolex 24 in 2015. The car co-driven by Colin Braun, Jon Bennett, James Gue and Mark Wilkins has a 68-second lead over the No. 8 Starworks Motorsport ORECA FLM09.
