The Cadillac V-Series.R, originally named the Cadillac V-LMDh, is a sports prototype racing car designed by Cadillac and built by Dallara. It is designed to the Le Mans Daytona h regulations, and debuted in the IMSA SportsCar Championship at the season opening 24 Hours of Daytona.[6][7] The car is also contesting the FIA World Endurance Championship from 2023 onwards.[8] The engine's 5.5L displacement is the largest displacement of any of the GTP cars debuted in the revival of the GTP class at the 2023 24 Hours of Daytona.[9]
Background
On August 24, 2021, Cadillac announced they would participate in IMSA's new GTP class and join the FIA World Endurance Championship's Hypercar class in 2023 using an LMDh-compliant racing design.[10] It was also confirmed on the same day that Dallara was chosen as the chassis supplier for their LMDh contender, and that Action Express Racing and Chip Ganassi Racing would campaign the car in the 2023 IMSA SportsCar Championship season as well as contest the 24 Hours of Le Mans.[11][12]
Cadillac released renders of the car on June 9, 2022. It was also announced that the car would use a hybrid powertrain, consisting of a 90° Naturally-Aspirated V8 internal combustion engine and standardized hybrid drivetrain components provided by Williams Advanced Engineering, Bosch and Xtrac, and that Chip Ganassi Racing would campaign one car in the 2023 FIA World Endurance Championship season.[13][14][15]
The first shakedown was completed in July 2022.[16] This was followed by testing at Sebring International Raceway and Road Atlanta, where the car covered nearly 19,312 km (12,000 mi).[17][18][19]
