The car is handbuilt around a central cage structure using various kinds of reaction-injected or sheet-molded plastic body panels, door skins, hood and decklid. The cage makes its presence known in the form of the very tall, wide central tunnel that houses the shifter, handbrake, and window switches, newly turned out in brushed metal instead of black plastic. They have left plenty of room for a roll cage inside the car.
The first and second generation Vipers were pretty wavy here and there, but the plastic body panels on the Vipers we drove were straighter, flatter, better fitting, and more uniform than on any previous Viper, so they have apparently improved their plastic parts manufacturing processes while they were finding more power, more torque and more chassis stiffness.
