As with its predecessor, Porsche offered the car in Coupé, Targa, and Cabriolet variants and, from the 1993 model year, a Speedster version, which featured a chopped-down front windscreen. Joining the 911 Turbo widebody variant were the exceptionally sporty and lightweight Carrera RS models. For the US, Porsche developed the 911 RS America.
With the introduction of the 964, Porsche offered the all-wheel-drive 911 Carrera 4 from 1988. It also included an automatically extending rear spoiler, dual ignition, knock control and a three-way catalytic converter. Porsche launched its Tiptronic automatic transmission in 1989. From 1991, Porsche equipped all 911 models with driver and passenger airbags as standard. The Carrera 4 was the first passenger vehicle fitted with a metal catalytic converter as standard.
