Braun’s Acura topped the 90-minute session for the 34-car entry with a quickest time of 1m07.341s, over three quarters of a second clear of all rivals at the fabled sportscar track near Toronto.
Ricky Taylor’s Wayne Taylor Racing with Andretti Autosport Acura ARX-06 set the early benchmark at 1m09.803s. That was soon pipped by Alexander Sims in Action Express Racing’s Cadillac V-Series.R and then Augusto Farfus in the #24 BMW M Hybrid V8 – keen to make amends after his first-corner exit at Watkins Glen last time out.
