Cadillac broke Mazda’s stay at the top of the Roar Before the Rolex 24 timing charts as Filipe Albuquerque set the fastest lap for Whelen Engineering Racing on Saturday afternoon.
In the fourth of seven IMSA WeatherTech SportsCar Championship pre-season test sessions, Albuquerque laid down a time of 1:36.441 to beat Mazda’s Ryan Hunter-Reay by 0.147 seconds.
This marked the first time of the weekend that Mazda Team Joest had been beaten to the top spot.
Third-quickest was Loic Duval in the No. 5 JDC-Miller Motorsports Cadillac, four-tenths off the pace, while Rengeet van der Zande slotted the Wayne Taylor-run Cadillac into fourth.
The No. 77 Mazda of Tristan Nunez rounded out the top five while the best of the Team Penske Acuras finished sixth as a result of Simon Pagenaud’s 1:37.446 effort.
Times in the 30-minute spell were generally slower than the preceding on-track opportunities due to cooler track conditions stemming from rain earlier in the day.
The GT Le Mans class order was led by Mathieu Jaminet in the No. 912 Porsche 911 RSR-19.
The Frenchman’s 1:44.542 tour put him three-tenths clear of James Calado in Risi Competizione’s Ferrari 488 GTE Evo, while Oliver Gavin lapped third for Corvette Racing.
In LMP2, Simon Trummer led the way with a 1:38.764 marker which set PR1/Mathiasen Motorsports out front.
Lexus, meanwhile, paced GT Daytona for the second time this weekend courtesy of Frankie Montecalvo’s 1:47.250 which put the AIM Vasser Sullivan driver three-tenths up on the Pfaff Motorsports Porsche driven by Zach Robichonn.
