The bodyshell of the Boxster 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 utilize specific material properties exactly where they are needed. Not only does this provide a high level of safety for the driver, it offers a considerable weight saving compared with the bodyshell of the previous model. This is why the doors of both luggage compartment lids are made from lightweight aluminum.
The crumple zones in the front and rear aprons 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.
