Porsche 911


"G" model (1973-1989)

  • Porsche 911 classic
  • Porsche 911 Carrera (G model)

For model year 1974, the Porsche 911 has been substantially revised. The most striking exterior of distinction is the higher and heavier bumpers, to go over the black plastic bellows in the body. These so-called "bellows-bumpers" were necessary in order to meet new U.S. crash test conditions, demanding a front-or rear-end collision on a barrier at a speed of 8 km / h without body damage. To this end, the bumpers on hydraulic impact absorbers connected to the body to absorb the impact energy. On other markets, these were replaced by lighter and cheaper standard baffle tubes.

They are the built in this form born 1974-1989, according to the internal name "G-series for model year 1974, commonly known as" G "model called (beginning with model year 1968, the A-series, was every year until 1979 . (M-series - the letter I was not given) indicated by a continuous letters of the alphabet, the year 1980, then the designation A-program).

For the 1974 model year the 911 was offered only in the variants 911 and 911 S and the new flagship 911 Carrera. Even with the less powerful variants was the capacity of the still air-cooled flat-six engine to 2687 cm ³ (2.7 liters) increased. Which carried 911 110 kW (150 hp), 911 S 128 kW (175 hp) and the Carrera 154 kW (210 hp). This was equipped with machinery from the legendary RS and was produced in similar quantities (Coupe: 1534 copies, Targa: 610 copies). Like its predecessor, the body of the new Carrera to accommodate the larger tires on the rear fenders by 42 mm was widened. Where the authorization permitted by legislation and has acted with a front spoiler lip and a distinctive, fitted on the hood mounted rear spoiler. The new Carrera was 1075 kg, the same weight as the 911 Touring RS and therefore offered identical performance.

For model year 1976 (J-series), the cubic capacity of 911 to 2993 cc (3.0 liters) was increased. At a speed of 6000 rpm, the engine in this release 147 kW (200 hp), which meant in terms of power reduction compared to the previous model 2.7 Carrera. The base engine with 110 kW (150 hp) was no longer offered; weakest engine was now the 2.7-liter engine of the previous S-911, whose output now without any technical modification with 121 kW (165 HP) was specified. For both models available on request semi-automatic "Sportomatic" had only three gears. Structural body parts were galvanized on both sides and Porsche could therefore offer a lifetime limited warranty of 6 years against rust perforation.

As the Porsche model range, already included the 924 and 928, was the 911 program of the model year 1978 (L-series) should be streamlined: The Carrera was accounted for - there was the 911 only as SC and Turbo. The 911 Carrera SC had the wide body and a three-liter engine with 132 kW (180 hp) with mechanical K-Jetronic. The car was in power and speed surpassed the type 928, which, according to the wishes of the Porsche lead in the 911 replace the 1980s.

In model year 1980 (A program) the performance of the SC to 138 kW (188 PS) was increased, the following model year 1981 by switching from normal to super gasoline to 150 kW (204 hp) further increased - the semi-automatic "Sportomatic" was not longer offered. There was now made the entire body made of double-dip galvanized steel sheets, was the long-term anti-perforation warranty be extended to seven years.

The plans of management before seen, let the 911 run in 1981. The future model portfolio should consist only of the modern water-cooled front engine car with 924, 944 and 928th After separation of the CEO by Peter W. Ernst Fuhrmann protection at the end of 1980, this plan was changed. As a signal for the realignment in 1981 at the International Motor Show in Frankfurt, the study of a Porsche 911 convertible with turbo engine and all wheel drive presented. From model year 1983 for the next SC Coupe and Targa, the convertible was offered as a third body variant.

Porsche 911 racing on trackFor model year 1984 (D program, from mid-1983) was the designation of SC Carrera changed and increased the capacity of the naturally aspirated engine to 3.2 liters, which now provided a power of 170 kW (231 hp). In place of the mechanical K-Jetronic was the fully electronic engine management system "Motronic (Digital Motor Electronics, DME) from Bosch. By the DME has been significantly reduced, especially the gas mileage of the car compared to the previous SC models (average of 17 liters of petrol per 100 km on 16 liters per 100 km). Caused by stricter emission regulations in the USA for the first time a catalyst for the 911 was offered. This came with catalyst models had a lower performance than the katlosen car. It was initially 152 kW (207 hp), but this was raised from 1986 to 160 kW (217 hp). At the request of the Carrera with a front spoiler lip and a large, flat rear spoiler has been delivered. This spoiler kit improved the factory in bene top speed of 245 km / h for the version without catalytic converter with 170 kW of auto, motor und sport tested 254 km/h.

In 1989, the G-model (K) program and in a limited series as a purist, roadster-like variant under the name "Speedster" sold, mainly by its shorter windscreen frame and two humps distanced visually on the top flap from the 911 Cabriolet. Furthermore, the Porsche Carrera offered in wide-body, to say with the broad wings of the 911 turbos. Due to the slightly worse aerodynamics of the "turbo wide" Carrera same engine performance was slightly slower than the "normal" Carrera. These models and also vehicles from special series, such as the limited edition Ferry Porsche count as sought collector's items and are found only rarely on the road.

Porsche 911 (1974), Porsche 911 Turbo (G model)

1974 Porsche built the first time the turbocharger in a production car. In the early 1970s, Porsche had achieved with turbo-powered cars like the Porsche 917/10 and 917/30 wide racing success and gained experiences that fed now in mass production. The new sports car with the internal development number 930 has been presented as a Porsche 911 Turbo. At the Paris Motor Show, Porsche introduced this year to the world's first production sports car with exhaust turbocharger and pressure control.

brought the car with 3 liters, it initially to a power of 191 kW (260 hp). The performance was taken for model year 1978 by a higher compression ratio, increasing the displacement to 3.3 liters and the use of an intercooler, which also required a larger rear wing, to 220 kW (300 hp). The fuel consumption of the turbo engines is substantially higher than those of a 911 without turbo at about 20 l/100 km. Typical features of the 911 Turbo is the much wider front and rear fenders and large rear spoiler with an even more massive spoiler lip rubber.
