Heritage:
Porsche has a long and distinguished history in motorsport and sports car manufacturing, with the 911 being its flagship model since 1963. The 996 generation marked a significant technological shift with the introduction of water cooling.
996 Evolution:
Introduced in 1997 for the 1998 model year, the 996 replaced the air-cooled 993. It featured a completely new chassis, body, and interior. Key updates included a more powerful and refined engine, improved aerodynamics, and enhanced safety features. Carrera 4 models offered all-wheel drive. Later iterations saw the introduction of the larger 3.6L engine and performance variants like the GT3.
