2006 Porsche 911 Carrera S for Sale in Thousand Oaks, California

The Porsche 911 lineup has been overhauled. For 2006, new Carrera 4 and Carrera 4S models join the Carrera and Carrera S models that were introduced for 2005. Cabriolet versions also join the 2006 Porsche 911 lineup. Essentially, every possible combination is available between coupe and cabriolet, 3.6-liter and 3.8-liter engines, rear-wheel drive and all-wheel drive.

Using Porsche's internal codename, all are new 997 models, replacing the 996 series produced since 1998. Only the Turbo continues to ride on the 996 platform.

These newest Porsches are thoroughly modern driving machines, packed with the latest in material advances, engine technology and electronic management. Yet one of the most striking things about them is that in some subtle but obvious ways, the 911 has devolved.
