The fourth generation of the 911 – the type 993 – is today considered one of the most desirable editions. Initially, Porsche offered it only as a Coupé and Cabriolet. The Targa made its debut in 1995, incorporating a new concept: instead of a removable folding roof panel, it had a glass roof with a large surface area, which could be retracted under the rear window. The era of air-cooled engines also ended in 1998 after the production of 68,881 vehicles.
