Sims and Cadillac sweep inaugural GTP championships

BRASELTON, Ga. (Oct. 14, 2023) – Cadillac Racing closed the inaugural IMSA WeatherTech SportsCar Championship Grand Touring Prototype season with multiple trips to the trophy stage following the 26th Motul Petit Le Mans, with the No. 31 Whelen Engineering Cadillac V-Series.R securing both driver/team titles.

Cadillac clinched its fourth IMSA Manufacturer Championship, fifth IMSA Michelin Endurance Cup Manufacturer Championship, fourth Driver/Team Championship, fifth IMSA Michelin Endurance Cup Driver Championship and third IMSA Michelin Endurance Cup Team Championship since entering IMSA prototype competition in 2017.

“You can’t ask for better than straight As. This program has been a challenge of resilience, and everyone has stepped up — all of the partners that are involved from GM, Dallara, our race teams, our hybrid-supplier partners. We delivered excellent results,” GM sports car racing program manager Laura Wontrop Klauser said. “It was not an easy year. We had our ups, and we had our downs. Ultimately our eyes were on the prize, and we were ready to seize any opportunity that was thrown at us.”

The No. 01 Cadillac V-Series.R, with Sebastien Bourdais, Renger van der Zande and Scott Dixon sharing duties behind the wheel, finished second to the No. 60 Acura ARX-06 under yellow.  Alexander Sims, Pipo Derani and Jack Aitken drove the No. 31 Whelen Engineering Cadillac V-Series.R to sixth place.

Less than 16 months since making its on-track test debut and 37 weeks since the opening race, the Cadillac V-Series.R has proven its reliability and performance on the variety pack of North American road and street courses. The Cadillac V-Series.R features an all-new Cadillac 5.5-liter DOHC V8 engine developed by GM’s Performance and Racing propulsion team based in Pontiac, Michigan, paired with the common energy recovery system.

Alexander Sims: “It’s been an incredible year. It’s pretty mad to think we’ve wrapped it up. A crazy race as we expected coming into this. Such a rollercoaster. Just so proud of the job that everyone has done. Pipo and Jack have done an insane job all year long.  The team has been flawless today. So many good pit stops. I’m so, so proud of everyone.”
