The 911 G-serie successor, referred to internally as type 964, was first shown in 1988. The first model variants of the 964 generation show just how advanced the new 911 was: all-wheel drive was introduced to the series for the first time on the Carrera 4, with Porsche having originally designed it for the 959 high-performance sports car. The 911 Carrera 2 with rear-wheel drive followed in 1989. Along with the Coupé, the Cabriolet and Targa versions also celebrated their debut at the same time. 85% of the 964 was made from newly designed parts. 63,762 third-generation Porsche 911s were produced within six years.
