In a session interrupted by numerous red flags as drivers tested Road America’s new pavement, Sebastien Bourdais set the benchmark for Cadillac Racing in Friday’s first practice session for the IMSA SportsCar Weekend at Road America. Bourdais turned a 1m49.538s on his final circuit in the No. 01 Chip Ganassi Racing Cadillac V-Series.R to claim the top spot.
That was only a tick ahead of Pipo Derani, who made it a Cadillac one-two in the No. 31 Action Express Racing Cadillac, 0.054s off Bourdais’ best. Augusto Farfus did a late 1m49.873s lap in the No. 24 BMW M Team RLL M Hybrid V8 for third. Filipe Albuquerque (No. 10 Wayne Taylor Racing with Andretti Autosport Acura) and Tom Blomqvist (No. 60 Meyer Shank Racing Acura ARX-06) rounded out the top five. Tijmen van der Helm was the quickest of the Porsche drivers in seventh, with the No. 5 JDC-Miller Motorsports 963 ahead of the factory Porsche Penske Motorsports machines.
