DesignEdit

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]
