The Porsche 911 G - that has changed

In the tenth year of its history, the Porsche 911 G-Model underwent its first major revision. Porsche itself speaks of the most profound changes that the sports car manufacturer has made to the Porsche 911 model series up to that point. has made. The background to this was a new regulation issued by the U.S. National Highway Traffic Safety Administration (NHTSA) in 1972. The Motor Vehicle Information and Cost Saving Act" required that a collision at speeds of up to eight kilometers per kilometers per hour must not cause damage to the car. This means that the vehicle should remain undamaged when moving forward or in reverse. remain undamaged. To achieve this, Porsche used the 911 G model's characteristic bellows bumpers with the rubber lip in front of the trunk lid. These redesigned bumpers were equipped with elastic bumpers for the U.S. market. Outside the American market, less expensive impact tubes were used. However, experience showed that these tubes deformed in the event of parking bumps, so that so Porsche decided to replace them. The impact absorbers for the American market could be ordered as an extra. The heavier, larger bumpers of the Porsche 911 G model compared to its predecessor earned it the nickname bellows Porsche. Greater safety is the guiding principle of the 911 G-series. As standard, they were equipped with three-point safety belts, with integrated head restraints in the front seats and impact surfaces on the sports steering wheels. The Porsche 911 G models were built from mid-1973 to mid-1989.

Porsche 911 G: Some visual changes

The variations to the bodywork involved other visual elements. The turn signal lamps at the front were integrated from the fender corners into the bumper integrated. A red reflector strip with the inscription "Porsche" was found between the taillights. Sport editions such as the Porsche 911 Turbo or also the Porsche 911 Carrera in the optional Turbo Look feature, in consideration of the wider tires, further outwardly shaped front and rear fenders. Less obvious to see were the differences such as the wheelbase, which was increased again in compared with the original model. Within Porsche, the respective model years were named alphabetically, starting in mid-1967 with the 1968 model year as the A-series to the 1979 model year with the M-series, whereby the letter I was not assigned. From 1980 onwards, Porsche then spoke of programs. For the 911 G model, it would be correct to refer to it as the G series. It was produced up to the K-program and ended with the production of the Porsche 964 successor model from 1988.

More performance for the road

The new Porsche 911 initially took over the displacement volume of the Porsche 911 Carrera RS with 2.7 liters. Only a little later, the displacement already increased to three liters. In 1983, it even brought it up to 3.2 liters and, in the new 911 SC RS, up to 250 hp. The Porsche engineers themselves were surprised by the great development potential of the boxer engine with air cooling. The entry-level model achieved 110 kW (150 hp), the Porsche 911 S model 129 kW (175 hp). From the 1974 model year onwards - with the exception of the Carrera - the 911s used the so-called K-Jetronic as an as an alternative to the complex mechanical 6-barrel injection pump. The new technology, developed by Bosch in cooperation with Porsche from 1970, ensured lower pollutant emissions and lower fuel consumption. The 911 Carrera was produced as a G-model for two years with built with an engine with a mechanical double-row injection pump. Like the Porsche 911 and especially the Porsche 911 Carrera RS from the series before it, the G-model Carrera has since achieved a high collector value. And this despite the high number of units - in total, the Porsche 911 G model was built over 198,414 times. It is thus a very successful 911 model.

The 911 G model - from the 1980s with catalytic converters

At the beginning of the 1980s, legislators in the USA, Japan and Europe tightened emissions legislation - for Porsche, the main sales markets of its vehicles. Porsche reacted and introduced catalytic converter technology in the E program starting in 1983. At the same time, the displacement was increased to 3.2 liters and the K-Jetronic was replaced by the Motronic electronic injection and ignition system (DME) with a so-called overrun cutoff from Bosch. One exception to this was the 911 Turbo (Porsche 930) built in 1974, which continued to use K-Jetronic until it was phased out in 1989. With engine's output increased to 170 kW (231 hp) with lower fuel consumption thanks to DME. With the modified technology of the air-cooled boxer engine in the rear, the Porsche 911 Turbo reached new performance peaks as a G model from 1974. In the process the turbocharging technology adopted from motorsport was used. From 1977, an additional intercooler and a displacement expansion to 3.3 liters were installed, bringing the sports car up to 300 hp. The driving performance remained unmatched by the competition. The Porsche accelerated from zero to 100 kilometers per hour in 5.2 seconds and reached top speeds of 260 km/h. The turbo makes it possible. In 1982, a Cabriolet was added to the Porsche 911 G model, followed in 1989 by a 911 Carrera Speedster, of which 2,103 were built with a wide body. with a wide body were built. In the 16 production years of the G series ran 198,414 Porsche 911 sold.
