Production of the second-generation Porsche 911 started in August 1973, complete with a body redesign. Improvements over its predecessor included the use of the 2.7 litre engine in the 911, 911S and Carrera models and the introduction of the K-Jetronic fuel injection system.
With each year of the second generation 911 production, improvements were made known as the G (1974), H (1975), I (1976) and J (1977) programs. All models came in both Coupe and Targa body styles and were also released with either a 5-speed manual, 4 speed manuals in earlier models or the Sportomatic transmission options.
The improvements made until 1977 included hot dip zinc coating for the entire body shell, a full width reflector placed between the taillights, improved heat regulation, electric door mirrors and face level air vents in the center of the dashboard.
