The Targa 4 and 4S versions were introduced in 2006.
Like its predecessors, the 993 and 996, the 997 Targa is equipped with a glass roof system.
At any speed, the roof can be opened where it drops down 25 mm and slides a metre back underneath the rear window.
As the roof weighs an additional 60 kg (132 lb), the suspension has been modified as compared to the other Carrera models.
When the glass roof is retracted, a small glass deflector is raised above the windshield to aid aerodynamic stability.

Unlike previous versions, the 997 Targa was only available with all-wheel drive.
Targa 4 models are slightly slower than the hard top Carrera models because of the heavier roof and the all-wheel-drive system.

The 997 Targa became available in the fall of 2006 as a 2007 Model.
In the first year, Porsche produced 1,760 cars worldwide (with 800 sold in the US market) out of the 38,922 911 models produced in total.
