Dane Cameron and Acura Team Penske led the way in opening practice for Sunday’s Sahlen’s Six Hours of The Glen.
Cameron reeled off a best lap of 1:33.562 in the No. 6 Acura ARX-05 in the 60-minute IMSA WeatherTech SportsCar Championship session, outpacing the No. 10 Wayne Taylor Racing Cadillac DPi-V.R of Jordan Taylor by 0.914 seconds.
Romain Dumas, fresh from a record-setting run in the Pikes Peak International Hill Climb, made a late improvement to third in the No. 54 CORE autosport Oreca 07 Gibson with a 1:34.490 lap.
It came after an incident by co-driver Colin Braun earlier in the session, which brought out the first of two red flags, when Braun tagged the wall in Turn 1.
Braun brought the car back to the pits under its own power but without its rear wing.
The No. 2 Tequila Patron ESM Nissan Onroak DPi of Ryan Dalziel and Tristan Vautier’s No. 90 Spirit of Daytona Cadillac DPi completed the top-five.
A number of times, including a 1:34 lap by Gustavo Yacaman in the No. 52 AFS/PR1 Mathiasen Motorsports Ligier, was disallowed due to track limits.
It would have put Yacaman fourth on the time charts.
Ford 1-2 in GT Le Mans
Richard Westbrook led a Ford Chip Ganassi Racing 1-2 in GT Le Mans, thanks to a 1:43.214 lap time by the Englishman.
Westbrook edged out the No. 66 Ford GT of Dirk Mueller by 0.206 seconds, with Patrick Pilet third in the No. 911 Porsche 911 RSR.
Lexus, meanwhile, topped the time charts in GT Daytona, with the No. 15 3GT Racing Lexus RC F GT3 of Jack Hawksworth posting a 1:45.443 lap.
It was 0.170 seconds quicker than the Jeff Segal-driven No. 63 Scuderia Corsa Ferrari 488 GT3 in second.
In addition to Braun’s incident, the No. 77 Mazda RT24-P of Oliver Jarvis crawled to a halt to trigger a second red flag with 20 minutes to go.
Jarvis’ car, which had reported electrical issues, did not rejoin the session
