The 1972-1983 Porsche 911, often referred to as the "G-Series" or "Impact Bumper" 911, represented a significant evolution for the iconic sports car. Following the introduction of the larger, more luxurious 911S in 1971, Porsche sought to modernize the 911 for the 1970s. This resulted in the G-Series, which featured substantial changes to the exterior, interior, and engine. The most significant visual change was the adoption of the "impact bumper" mandated by US regulations for vehicles produced after 1972. These bumpers, along with other styling updates, contributed to a less elegant but more practical design. Additionally, the G-Series saw the introduction of the 2.7-liter engine, which offered improved performance and fuel efficiency compared to its predecessor. The 1972-1983 Porsche 911 models remained true to the renowned handling and performance expectations associated with the 911 name, offering a thrilling driving experience.

The G-Series proved to be a transitional phase for the 911, with the 1974 model year marking the final year of the 2.4-liter engine. The 2.7-liter engine remained the standard powerplant, offering various output levels depending on the model. The 911T, denoted by "T" for "Touring," featured a less powerful version of the 2.7-liter engine, while the 911S boasted a higher output engine with improved performance. The G-Series 911 also saw the introduction of the Carrera model in 1973, featuring a wider body and a 2.7-liter engine with a larger displacement. The Carrera, with its improved handling and power, soon became the flagship model of the G-Series. Despite the numerous changes, the G-Series 911 remained a desirable and capable sports car, showcasing the evolution of Porsche's engineering prowess and design philosophy.
