The bodyshell of the Cayman models is based on an intelligent lightweight principle involving the composite construction of aluminum and steel. The use of dissimilar but precisely combined components makes it possible to utilise specific material properties exactly where they are needed. Not only does this provide a high degree of safety for the driver, it also offers a considerable weight saving compared with the bodyshell of the previous model. This is why the doors, luggage compartment lid and rear hatch are made entirely of lightweight aluminum. Aluminum accounts for around 44% by weight of the entire bodyshell.
The crumple zones in the front and rear fascias feature integral light-alloy bumpers, while impact absorbers offer additional safety. For the protection of occupants, energy-absorbing padding is used selectively in important areas within the passenger cell.
