Acura’s domination of its home IMSA WeatherTech SportsCar Championship race has been extended to the third hourlong practice session of the weekend, which saw Dane Cameron and Helio Castroneves place Team Penske’s two Prototype entries atop the timesheet once again.
On the 17th of 32 total laps turned during the Saturday morning outing for the No. 6 Acura ARX-05, Cameron turned a 1:12.675, marking the fastest lap of the weekend leading into qualifying.
Castroneves was 0.088 seconds back in the No. 7 Acura DPi and, remarkably, was the only other driver who lapped within a second of Cameron’s pace.
At 1:13.767, Jonathan Bomarito reached the third slot on the results sheet in Mazda Team Joest’s No. 55 Mazda RT24-P, but was still 1.004 seconds back from the slower Acura.
Colin Braun and Oliver Jarvis were fourth and fifth in CORE autosport’s No. 54 ORECA 07 and the second Mazda DPi, placing an LMP2 car in fourth and both Mazdas in the top five.
Entering qualifying, Performance Tech Motorsports’ ORECA was 2.721 seconds off the pace as it brought up the rear of the Prototype division.
Bamber Well Ahead in No. 912 Porsche
While Penske’s pair of Acuras have taken turns topping Prototype, the same car set the fastest lap in each of the three one-hour practice sessions in GT Le Mans.
After opening the weekend atop the class with the fastest GTLM lap in Practice 1, Earl Bamber returned to the position having turned a 1:18.590 on his best revolution of the 2.258-mile road course in the No. 912 Porsche 911 RSR.
Remarkably, the second-fastest driver in the class, Antonio Garcia in Corvette Racing’s No. 3 car, was nearly four-tenths off Bamber’s leading time.
BMW Team RLL was represented in third with its No. 24 BMW M8 GTE as Jesse Krohn lapped within 0.521 seconds of Bamber. Nick Tandy and Ryan Briscoe comprised the remainder of the top five in the No. 911 Porsche and No. 67 Ford GT, respectively.
The second Corvette C7.R was eighth and last in the class in Practice 3, with Tommy Milner’s best lap being 0.976 seconds slower than Bamber in the class-leading Porsche.
