Helio Castroneves set the fastest lap in a trouble-free warmup session for this afternoon’s IMSA Road Race Showcase at Road America.
The Team Penske driver posted a time of 1:50.947 behind the wheel of the No. 7 Acura ARX-05, beating his teammate Juan Pablo Montoya in the No. 6 car by two-tenths of a second.
Castroneves and Ricky Taylor will start today’s race from second on the grid, sharing the front row with Montoya and Dane Cameron.
Third-quickest in the warmup was Tristan Nunez, who steered the No. 77 Team Joest Mazda RT24-P DPi that will start third on the grid to a time of 1:51.781.
Nunez was followed closely in the leaderboard by his Mazda teammate Harry Tincknell, while Tristan Vautier set the best Cadillac DPi-V.R time in the No. 85 JDC-Miller Motorsports car.
BMW Team RLL led the way in GT Le Mans, courtesy of Tom Blomqvist’s 2:01.794 effort aboard the No. 25 BMW M8 GTE.
