One championship-contending DPi was traded for the other atop the running order at Michelin Raceway Road Atlanta as Dane Cameron followed the top Practice 1 performance from his rival Felipe Nasr with the top lap in Thursday’s second session.
- Results: 2019 Motul Petit Le Mans
Driving the points-leading No. 6 Acura ARX-05 of Team Penske, Cameron nearly identically matched the quickest lap Nasr and the No. 31 Action Express Racing Cadillac DPi-V.R laid down in the morning session. Hours after Nasr’s 1:09.093, Cameron was just two-thousandths of a second slower at 1:09.095.
Twelve points separate these DPi entries on the championship leaderboard heading into Saturday’s 10-hour contest and four cars split them on the Practice 2 timesheet. Tristan Vautier, Filipe Albuquerque, Renger van der Zande and Ricky Taylor filled positions two through five in their Cadillac and Acura prototypes while Pipo Derani and the No. 31 Whelen Engineering Cadillac DPi placed sixth. Derani was the final driver within a second of Cameron.
Mazda Team Joest’s DPi duo was seventh and eighth, 1.005 and 1.339 seconds off the top lap. Tristan Nunez took the No. 77 Mazda RT24-P off track to initiate one of the session’s four red-flag periods, which combined to eat up just over 20 minutes of potential track time.
NTT IndyCar Series regular Spencer Pigot was two seconds in arrears of Cameron as he prepares for his first IMSA WeatherTech SportsCar Championship race in Juncos Racing’s Cadillac.
Gabriel Aubry made PR1 Mathiasen Motorsports the quicker of the two LMP2 teams while, in GT Le Mans, Daniel Serra moved Risi Competizione into the top spot after the lone Ferrari 488 GTE in the field settled for second in Practice 1. Unofficially, Serra went 0.298 seconds under the standing GTLM lap record at the 2.54-mile Michelin-branded venue.
The quickest cars from Corvette Racing, Chip Ganassi Racing and the Porsche GT Team occupied the next three positions in GTLM with Antonio Garcia, Scott Dixon and Laurens Vanthoor chasing the Risi Ferrari in those positions. Joey Hand completed the top five in the second Ford GT, just within half a second of Serra.
Felipe Fraga put four-tenths of a second between his Riley Motorsports-prepared Mercedes-AMG GT3 and the Audi R8 LMS GT3 of Montaplast by Land-Motorsport at the head of the GT Daytona field with a lap 0.109 seconds under the Road Atlanta record for the GT3 category.
Ferrari, BMW and Acura were represented in the three remaining top-five positions due to the fastest laps by Toni Vilander, Robby Foley and Justin Marks of Scuderia Corsa, Turner Motorsport and Meyer Shank Racing, respectively.
