996 GT3 MKI 1999-02

Porsche introduced a road-legal GT3 variant as part of the 996 series, directly inspired by the company's racing car used in GT3 class racing. Known simply as the GT3, this model embraced lightweight construction, featuring thinner windows and the removal of rear seats. Drawing from Porsche's rich racing heritage, the GT3 prioritized agility and performance, echoing the ethos of the iconic 1973 Carrera RS.

The GT3 underwent significant modifications to enhance handling and responsiveness. Its suspension system was fine-tuned for precision and sharpness, sacrificing some comfort for heightened performance. However, the most notable aspect of the GT3 was its engine. Departing from the water-cooled units used in other 996 models, the GT3 was equipped with a naturally aspirated engine derived from the 911 GT1 '98 sports-prototype racing car. Constructed with lightweight materials, this engine boasted higher rpm capabilities.

The initial iteration, often known as the Mk.I GT3, made its debut in 1999 across global markets, excluding North America. Equipped with a naturally aspirated 3.6-liter flat-six engine, it boasted an impressive maximum power output of 265kW (360PS; 355hp). This engine, shared with the 996 Turbo, derived from the powerplant engineered for the 911 GT1 race car.
