Design
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.[3]
