The 997.1 Targa 4 was introduced for model year 2007, fitted with a panoramic, retractable glass roof to give both more sunlight when closed and more fresh air when open than a traditional sunroof. In the 997.1 generation, the Targa variant was only available as an all-wheel drive model – thus the models were Targa 4 and Targa 4S – each with the powertrains found in the 997 Carrera 4 and 997 Carrera 4S.
