The Porsche 996 was the first water-cooled 911 and one of the most important generations in the model’s history. Produced from 1998 to 2005, it introduced an entirely new platform and expanded to include everything from the Carrera and Carrera 4 to the Turbo, GT2, GT3, and several special editions. Early cars used a 3.4-liter flat-six before Porsche increased displacement to 3.6 liters in 2002. Today, the 996 is valued for its analog driving experience, compact dimensions, and relative affordability compared with later 911 generations. The guide below shows every major 996 variant, including engine changes, drivetrains, power outputs, and special editions.
