Background
To mark the milestone birthday of the iconic 911 sports car, the engineers in Weissach designed a particularly purist and driving-pleasure-oriented sports car: the 911 S/T. The exclusive anniversary model offers a unique combination of agility and driving dynamics. Its naturally aspirated 386 kW (525 PS) four-liter flat-six engine is combined with a close-ratio manual gearbox. Added to this is a systematically lightweight construction philosophy – down to the smallest detail – and a chassis setup optimized for agility and drivability. The name identifies the new 911 S/T as a descendant of a particularly sporting version of the first-generation 911. From 1969 onwards, Porsche offered the 911 S as a special competition version, and it was internally called the 911 ST.
