The 911 G series was presented at the IAA (International Motor Show) in Frankfurt on September 12, 1973. Serial production began in 1974. This model is actually a deeply modernized version of its predecessor. The basic engine of this model was a naturally aspirated 2.7-liter engine. In later years, engines with capacities of 3.0 and 3.2 liters were added to the lineup.
The production version of the Turbo model was presented in 1974 in Paris. The 930, as this model was named, initially featured a 3.0-liter engine producing 191 kW. In 1978, a series of modifications were made to the turbo version. The engine capacity was increased to 3.3 liters, and an intercooler was installed, allowing for the use of a smaller turbocharger. This resulted in reduced turbo lag and an impressive power output of 221 kW, which was remarkable for that time. It is worth noting that this was the fastest production car available on the German market. New brakes, developed by the racing department, were also installed.
In 1986, Targa and Cabriolet body styles were introduced to the Turbo lineup. In 1989, the Speedster version was launched, after which the production of the G model was concluded.
