Caddy takes 1st and 2nd place in DPI class
and Corvettes were the only 2 cars in the GTLM class and also take 1st and 2nd place

Renger van der Zande was able to hold off a hard charging Felipe Nasr to give Chip Ganassi Racing its first IMSA WeatherTech SportsCar Championship victory with Cadillac in Saturday’s Chevy Sports Car Classic in Detroit’s Belle Isle.

The Dutchman survived a late-race caution & restart with three minutes to go to edge out the No. 31 Action Express Racing Cadillac DPi-V.R by 0.573 seconds.
Having led from green, the No. 01 Cadillac held control of the 100 minute race, which was appearing to come down to a fuel mileage race until a full course caution with nine minutes to go.

Flipe Albuquerque limped the DPi championship-leading Wayne Taylor Racing Acura ARX-05 home in third with an apparent issue.
Co-driver Ricky Taylor battled handling issues in his opening stint but capitalized on pit strategy to jump from fifth to third.

The No. 55 Mazda RT24-P of Oliver Jarvis and Harry Tincknell finished fourth, marking the pairings first non-podium finish of the season.

GTLM saw the No. 4 Chevrolet Corvette C8.R of Tommy Milner & Nick Tandy come out ahead of teammates Jordan Taylor & Antonio Garcia.
It came despite radio communication issues for Milner during his stint.
