The Cadillac DPi-V.R is a prototype racing car which started competing in the IMSA WeatherTech SportsCar Championship in North America in 2017. It is the successor to the Corvette DP. It marked Cadillac's début to sports car racing as a full constructor since Cadillac Northstar LMP that competed in American Le Mans Series from 2000 to 2002. It was unveiled on November 30, 2016.[2]

Design

Cadillac DPi-V.R is the variation of Dallara P217 base. The car was designed to compete in the DPi Prototype class. The car's first win came at the 2017 24 Hours of Daytona by Wayne Taylor Racing.[3] A closed-top design, it incorporates several new mechanical and safety features not used in the previous Corvette DP car. Zylon anti-intrusion panels are built into the frame that prevent any mechanical components from coming into the chassis in the event of an accident. The Cadillac DPi-V.R. has an electrical power steering system and an improved gearbox.[4]
