The aerodynamics of the Porsche 992

With the new 911, Porsche has further developed the mixed body construction throughout the vehicle and designed a completely new body structure. The steel share of 63 percent in the previous model has now been more than halved to 30 percent, for example. Apart from the front and rear aprons, the outer skin is now made fully of aluminium. The new door design, made from aluminium sheet, reduces the bodyshell weight without negatively impacting stability or quality.

In addition to high-strength steels, there is increased use of extruded aluminium profiles in the bodyshell, 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 has also used more die-cast aluminium parts on the new 911. These components include the front spring strut mount, rear tunnel housing, rear carrier, and shock absorber mounts, for example.

The body components grouped directly around the passenger cell, as well as the A and B pillars and side roof frame, are made from ultra high-strength, hot-formed steels. These absorb the main loads to meet crash requirements and contribute to the intelligent lightweight construction: to achieve comparable strength using aluminium components would require additional bulk and more weight. For the first time worldwide, the new 911 Carrera Coupé also has a curtain airbag.
