Rolex 24 Hour 1: Acuras start fast

Running under the radar in the pre-race buildup, the Acura Team Penske cars were running 1-2 at the one-hour mark of the 57th Rolex 24 At Daytona. Juan Pablo Montoya in the No. 6 leads Ricky Taylor's No. 7, followed by the No. 77 and No. 55 Mazdas, with the No. 5 Action Express Cadillac of Filipe Albuquerque leading six Cadillacs and the lone Nissan.

Class leaders were: LMP2, No. 38 Kyle Masson; GTLM, No. 911 Nick Tandy; and GTD, No. 86 Trent Hindman.

Standings

Ryan Briscoe, running fourth in GTLM, took the No. 67 (Castrol livery) Ford GT to the garage at the 48-minute mark. Last year, the Chip Ganassi Racing Fords dominated the class with a 1-2 finish. Both Briscoe and the No. 912 Bamber are now several laps down in GTLM.

Jarvis led the opening 18 laps before his first pit stop. Felipe Nasr, Jordan Taylor and Ricky Taylor then took turns at the lead before Montoya passed teammate Taylor to lead on Lap 22.

A few firsts:

First car to the garage -- Alfred Renauer in the No. 99 NGT Motorsports 20 minutes into the race, reporting, “It’s undriveable.”

First car with bodywork damage -- Roberto Gonzalez in the No. 18 DragonSpeed ORECA Gibson in the LMP2 class, also after 20 minutes.

First class contender to pit: Earl Bamber in the No. 912 Porsche at the 27-minute mark.

First overall contender to pit: Jonathan Bomarito in the No. 55 Mazda, at the 30-minute mark. Polesitter Jarvis pitted on the following lap.

While A.J. Allmendinger spent the opening hour in the NBC Sports booth, his car (the No. 86 Acura) led in GTD. This marks the 13th consecutive time that his car led the Rolex 24, although Allmendinger led all 12 of his starts.
