Robin Liddell’s late charge to second across the finish line wound up netting the IMSA Michelin Pilot Challenge race win Sunday at Road America.
Liddell and co-driver Frank DePew pushed the No. 71 Rebel Rock Racing Chevrolet Camaro GT4.R from the 17th starting position in the Grand Sport (GS) class to cross the finish line 3.229s behind the No. 57 Winward Racing Mercedes-AMG GT GT4 at the checkered flag of the Road America 120. But following post-race technical inspection, the Mercedes was found to have exceeded its fuel capacity and moved to the rear of the class in the provisional results.
The resulting win is the first of the season for Liddell and DePew and comes on the heels of a second-place finish last month at Canadian Tire Motorsport Park. The revised results put a pair of Ford Mustang GT4s on the GS podium, with the No. 59 KohR Motorsports Mustang shared by Bob Michaelian and Luca Mars taking second place and the No. 13 McCumbee McAleer Racing with AEROSPORT Mustang co-driven by Jenson Altzman and Chad McCumbee placing third.
The race became one of differing fuel strategies and mileage, with a potential BMW podium sweep going awry when the Nos. 95 and 96 Turner Motorsport and No. 92 Random Vandals Racing entries all forced to pit for a splash of fuel with eight minutes to go in the two-hour race.
That promoted Daniel Morad in the No. 57 Winward Mercedes to the front, which he held to the checkered flag – only to have the result negated by the post-race penalty. The win is the 15th of Liddell’s Michelin Pilot Challenge career and the sixth for DePew.
The GS points-leading No. 72 Murillo Mercedes also needed to pit and ended in 11th place.
