Targa 4S was introduced in 2006 as a version for the Porsche Carrera 4 – 997.
While it was heavier than its coupe sibling, the powerful engine helped it to be almost as quick its coupe brother.

The airy feeling into a glass-roof vehicle cannot be described. The Porsche management decided to come back on the market with Targa versions for the 911 – 997 generation. That meant to have a removable side of the roof, over the front seats. The idea was not entirely new, but the way it did it, it was.

The car featured two glass panels that blocked the ultraviolet radiation but remained transparent. Thus, the heat transfer was smaller than on a regular glass panel. To offer better protection, a power shade was included. The front part of the glass slid opened and offered a true Targa experience. Unlike other 911s, the Targa 4 S featured hatch-style access. The rear glass was a tailgate, with hinges mounted over the B-pillars. That allowed it to open and provide access to an additional, 230 liters (8.1 cu-ft) storage area behind the rear seats. The roof was opened and closed in seven seconds.

The interior was offered with a choice of two steering wheels and four types of seats. The PCM (Porsche Communication Management) was fitted as standard, but the DVD-based navigation system was on the options list.

For the engine, the Targa 4S featured a 3.8-liter engine that offered 355 hp, 30 more than the non-S version. It was mated as standard to a 6-speed manual, while a 5-speed automatic with manual override (Tiptronic) was on the options list.
