The Porsche 911 Targa 4S (997) is a special variant of the Porsche 911 Carrera 4S (997). Like the previous Porsche 911 Targa models, it is noticeable for its retractable glass roof. The 997 Targa was the first in the Targa lineup to be sold exclusively with an all-wheel drivetrain. Performance-wise, the Targa 4S has no particular difference to the Carrera 4S. The price of the Targa 4S was $3,000 cheaper than the Carrera 4S Cabriolet.
