911 G (1974-1989)

Technical data

The Porsche 911 G series was manufactured from 1974 to 1989. Each model year was internally designated with a consecutive letter, so technically only the 1974 model year is referred to as the G model, although "G-model" has often been colloquially used to describe the second generation of the 911. In MY 1974, Porsche introduced impact bumpers to comply with low-speed protection requirements of U.S. law. These bumpers were seamlessly integrated into the design and remained unchanged for 15 years. Additionally, the engine size was increased to 2,687 cc in 1974, resulting in a torque boost. The 911 and 911S models retained the narrow rear wings of the old 2.4 version, now equipped with a detuned version of the RS engine producing 150 and 175 PS (110 and 129 kW; 148 and 173 hp), respectively. In 1975, Porsche unveiled the first production turbocharged 911. While known as the Porsche 911 Turbo in Europe, it was marketed as the Porsche 930 (with 930 being its internal type number) in North America. Featuring wide wheel-arches to accommodate wider tires and a large rear spoiler often called a "whale tail" for the early cars, and "tea-tray" for the later ones. its engine initially produced 260 PS (191 kW; 256 hp) with a 3.0 L capacity, later increasing to 3.3 L and 300 PS (221 kW; 296 hp) by 1978. These early models were renowned for their exhilarating acceleration paired with challenging handling characteristics and extreme turbo lag. In 1978, Porsche introduced the new version of the 911, the '911SC'. Initially, its power output was 180 PS (132 kW; 178 hp), later increased to 191 PS (140 kW; 188 hp), and then further to 204 PS (150 kW; 201 hp) in 1981. The first 911 Cabriolet debuted in late 1982 as a 1983 model, marking Porsche's return to offering a cabriolet since the mid-1960s with the 356. Despite its premium price compared to the open-top targa, it proved highly popular, with 4,214 units sold in its introductory year. Cabriolet versions of the 911 have been offered ever since. Replacing the SC series in 1984 was the 911 3.2 Carrera, featuring a new, higher-displacement 3.2-liter horizontally opposed flat 6-cylinder engine. Power output increased to 207 hp (154 kW; 210 PS) for North American-delivered cars and to 231 PS (170 kW; 228 hp) for most other markets. The 915 transmission from the SC series was retained for the first three model years, but in 1987, the Carrera received a new five-speed gearbox sourced from Getrag, model number G50, featuring proven Borg-Warner synchronizers and a hydraulically operated clutch.
