Mechanical Components

The RHT is a roof system which consists of a three piece sheet steel design. The roof system withstands speeds up to 167 mph
(270 km/h) and has a sophisticated water management system for draining remaining water when the roof is extended or retracted.
Aerials (AM/FM) are integrated into the bonded rear window. The hardtop roof panels (shells) are made of sheet steel in a classic
"sandwich" construction and are engineered for optimum weight and rigidity.
A central hydraulic system in the luggage compartment floor provides the hydraulic pressure for movement of 8 hydraulic cylinders
in the overall system.
The retractable hard top (RHT) consists of two main (major) sections; the roof module and the rear module.
