Lightweight Body Thanks to Multi-material Design

The body of the new Porsche 911 is 7 % lighter than its predecessor. This is thanks to a further refined hybrid design using aluminum, steel, and composite materials. Despite the drop in weight, there is no loss of stability, rigidity and safety, which have even been strengthened in some areas compared to before. The company is using hybrid construction for an A-pillar for the very first time. The reinforcement with organic sheet, injection- molded ribs, and structural foam replaces the previous reinforcement using high- tensile steel tubing. The A-pillar itself comprises higher- and maximum-strength sheet metal components made from e.g. boron steel. Except for the front apron and rear trim, the car's outer shell is all-aluminum. The sidewall of the coupé alone reduces the overall weight by around 12 kg. Besides high- tensile steel, greater use has been made of extruded aluminum profiles for the body shell, for example in the...
