On the series’ debut on the tight and twisty 1.654-mile, nine-turn temporary street circuit in downtown Detroit, Eng beat Nick Tandy’s Porsche and Cadillac’s Sebastien Bourdais to the fastest time in this two-hour session for GTP and GTD Pro cars.
The FP1 pacesetting #6 Porsche Penske Motorsport 963 of Tandy and Mathieu Jaminet was given a 10-minute hold at the start of the session due to a tire carryover infringement. The early stages were interrupted anyway by a red flag after the #64 Ford Mustang GTD entry of Harry Tincknell went off at Turn 1.
