Purpose of the System
- The aim of BMW development was to achieve a high degree of rigidity in combination with low weight. This objective was achieved by using aluminum in a space frame design.
- The body of the Z8 roadster has been developed as a solid aluminum structure that combines an aluminum space frame with bolt on aluminum outer skin paneling. This design therefore renders necessary repair methods specific to aluminum.
- The aluminum outer skin panel consists of aluminum-magnesium-silicon alloy. The body framework is made up of extruded sections. The entire frame work has a weight of 225kg (496 lbs.).
- The bodyshell of the Z8 consists of a total of 287 parts, of which 87 parts are extruded sections.
