“While it is often said that nothing can be all things to all people, there are rare exceptions. The 911 Targa 4 and 911 Targa 4S certainly fall within that category, offering the open-air driving enjoyment of a cabriolet with the security and weather protection of a coupe.
In a 911 Targa 4 and Targa 4S, you can quickly tailor the driving environment as your mood or the temperature changes.
Both Targa 4 models have an electrically operated glass roof panel which forms an integral part of the bodyshell structure. Building on the same basic platform as the 911 Carrera 4 and 4S models, the Targa roof provides a unique sense of space and light – even when the roof is closed. Your surroundings become part of the driving experience, whatever the season, whatever the weather, whatever the time of day or night. Amen.”
