#Porsche #911: Highlights of #Lightweight-#Composite #Construction - On the #Multimaterial #Mix in the Porsche 911
The new #911 is lighter than ever due to a mix of more aluminum, less steel, and new composite materials, making the total weight 7% less than its previous model, according to Porsche. This new multimaterial mix gives the sports car not only a lighter but also a more stable, safer, and stiffer frame.
For instance, a #hybrid #construction of plastics provides excellent protection against rollovers in the A-pillar. Replacing the high-strength steel reinforcement, this new technique reduced the overall weight by 2.7 kilograms, lowering the center of gravity, and improving the car's performance.
Despite the new 911's larger dimensions, the development and use of intelligent material mixes that combine increased aluminum and less steel keep the new model's weight comparable to its predecessors.
The #lightweight outer skin of the new 911 is entirely made of aluminum except for front and rear parts. #Porsche used ten different #manufacturing techniques to assemble the car's body shell and has optimized the production process to include new materials like #organoblechs, multi-layer #composite materials glued together as #structural reinforcements.
The new #911's doors are made of aluminum for the first time, resulting in some weight reduction. An additional twelve kilograms are shed due to a new inner door panel construction method.
