Against a tide of Daytona Prototype international machinery in the Prototype class, Colin Braun turned the fastest lap in opening IMSA WeatherTech SportsCar Championship practice at Canadian Tire Motorsport Park to put an LMP2 car in the top spot.

Even though DPis hold a significant numbers advantage at CTMP with eight representatives in the 13-car class, Braun beat all of them to the top of the timesheet with a 1:07.155 in his No. 54 CORE autosport ORECA 07. The lap put him 0.916 seconds clear of Dane Cameron, who ended the hourlong session second fastest in his No. 7 Team Penske Acura ARX-05.

Cadillac rebounded from a difficult weekend in Watkins Glen with the third-fastest lap attributed to Action Express Racing’s Filipe Albuquerque. Jonathan Bomarito was fourth fastest in his No. 55 Mazda RT24-P, one-tenth of a second quicker than Felipe Nasr in the second Action Express Cadillac.

Ricky Taylor, Stephen Simpson, Renger van der Zande, Simon Trummer and Pipo Derani completed the top 10 ahead of Oliver Jarvis and Gustavo Yacaman.

Performance Tech Motorsports’ No. 38 ORECA 07 brought up the rear of the Prototype field after sustaining heavy damage in a Turn 1 crash.

Bamber Puts Porsche on Top of GTLM

Much like practice and qualifying at Watkins Glen, the four manufacturers competing in GT Le Mans ended Practice 1 in order with the pair of Porsche 911 RSRs ahead of the rest of the eight-car class.

Earl Bamber turned the fastest lap in his No. 912 machine, 0.493 seconds quicker than Nick Tandy in the sister No. 911.

Two sets of American cars trailed the German duo with Corvette Racing’s bright yellow pair ahead of Chip Ganassi Racing’s Ford GTs. Jan Magnussen was 0.081 seconds quicker than teammate Oliver Gavin for third and fourth, respectively, while fifth-fastest Dirk Mueller was 0.126 seconds quicker than Richard Westbrook who ended the session in sixth.

The pair of BMW M8 GTEs of BMW Team RLL were relegated to the rear of the class with Jesse Krohn 0.154 seconds faster than Alexander Sims.

Bill Auberlen, back with Turner Motorsport for the CTMP weekend, put the Watkins Glen-winning No. 96 BMW M6 GT3 on top of GT Daytona with a 1:16.848.

Auberlen’s best lap around the 2.459-mile circuit was just 0.081 seconds clear of Jack Hawksworth in 3GT Racing’s No. 15 Lexus RC F GT3, who ended Practice 1 with the second fastest lap.

Jeff Segal was third quick in his Scuderia Corsa Ferrari 488 GT3 ahead of Kyle Marcelli’s Lexus and Jeroen Bleekemolen in Riley Motorsports’ Mercedes-AMG GT3.

GTD championship leaders Bryan Sellers and Madison Snow ended Practice 1 at the bottom of the timesheet but just six-tenths of a second slower than best in class.

The 32-car field will be back in action Friday for Practice 2 at 3:50 p.m. EDT.
