Porsche developers took a different approach in the new Porsche 911 using different plastic materials to create a hybrid design that guarantees a high degree of occupant protection.

The consistently evolved composite design – which now consists of more aluminium, less steel and new composite materials – once again cuts the weight of the body shell by around seven percent, without making any compromises in terms of stability, rigidity and safety, which are all at least at the same exemplary level set by the predecessor model.

To achieve this, Porsche developers took a different approach by using different plastic materials to create a hybrid design in the Apillar. This guarantees a high degree of occupant protection in the event of the vehicle overturning. This innovative solution replaces the previous tube reinforcements made of super high strength steel. The greatest benefit being that the new reinforcement cuts the overall weight by 2.7 kilograms and also lowers the centre of gravity. Both effects have a direct impact on the outstanding handling dynamics of the sports car.

Materials and production processes define the ideal connection technology: welding, bonding, clinching, screw connections – no less than ten methods are involved in assembling the body of a new 911.

In addition to high-strength steels, more extruded aluminium profiles were also used in the body shell, such as for the front and rear longitudinal members, inner and outer door sills and floor reinforcements. Their share has been increased from three to 25 percent.

Porsche also uses more die-cast aluminium parts in the new 911, for instance as part of the front spring strut mount, rear tunnel housing, rear longitudinal members and impact absorber mounts. The benefit of die-casting is that even complex, geometrical components can be produced as one single component. Reinforcements or screw connections no longer have to be produced and welded individually. As a result, the component not only becomes lighter, but production steps also become obsolete, making production more efficient.

The body of the new 911 consists of a multi-material mix and is thus taking the next big step in intelligent light-weight design, advancing the weight reduction strategy started by the predecessor model. At the same time, the evolved body concept also guarantees higher rigidity. Compared with the predecessor model, the 911 Coupé delivers better torsion and bending values. As a result, the 911 stays unwaveringly on course even when driven with a sporty driving style on sections of road with different surfaces.
