Porsche 911 G-Body - The Story

There is a common misconception that all 911s built between 1974 and 1989 are 'G-series' cars. In fact, the G-series was only produced for the 1974 model year. It was followed by the H, J, K, and so on. We refer to them a "G-Model" or "Second Generation 911s" because they are all new bumper designs. The 1974 model year brought many significant changes to the 911 to meet legislative requirements around the world for both impact safety and emissions that it is the start of the G-body cars, and thus is referred to as the second generation 911. We cover the full story from 1974 until 1989 below.

Porsche 911 G-Body Model Timeline

2nd Gen Porsche 911 Model Guides (1974 - 1989)

Below, we take you through in-depth guides for each and every Porsche 911 model between 1974 and 1989. We have summarized the core variants above, so just dive in to get under the hood now.

The base model Porsche 911, along with the 2.7 Liter 911S and Carrera 2.7, was introduced for the 1974 model year with many significant changes to meet legislative requirements around the world for both impact safety and emissions. It was available in Coupe and Targa variants, sporting engine Type 911/92 with K-Jetronic fuel injection, rated at 150 hp. For the 1975, the base model was discontinued in North America. ROW got Coupe and Targa variants, featuring engine Type 911/41 rated at 150 hp.
Production of the second generation 911 started in August 1973. The 1974 model year G-series derivative replaced the outgoing 1973 model year F-series. Visually, the new 911 was given a major facelift and all three production variants now came with fuel-injected 2.7-litre engines. The entry level 911 had 150bhp, the mid-range 911 S offered 175bhp and the flagship 911 Carrera came with 210bhp. Once again, customers were given the choice of either Coupe or Targa body styles.
In 1974, Porsche's performance version of the 911 was simply known as the 911 Carrera. It had new bumpers that complied to American regulations and the 2.7-liter engine from the Carrera RS 2.7. Other new features for 1974 included new seats, a full-width rear taillight. The Carrera deleted all the chrome off the car in favor of black window frames, wipers, doorhandles, but chrome could be ordered as an option. In 1976 Porsche replaced the Carrera with a new 3.0 liter variant.
In 1974 Porsche offered a high performance fuel injected Carrera specifically for the European market. These were close to 2.7 RS specification and are often referred to as the 2.7 or Euro Carrera. In many regards, this car is similar to the 1973 2.7 RS in touring trim, with its 210bhp 911/83 engine, but the 2.7 Carrera is based on the updated G-series body and interior. Later Carreras that reach American shores used had reduced power and throttle response compared to Euro counterparts.
As a successor to the Carrera 2.7 MFI, the Carrera 3.0 was fitted with a variation of the 930's engine without a Turbo. During its production period only 3,687 cars were made. The Carrera 3.0 was replaced by the Porsche 911 SC for model year 1978. Between 1976 and 1977, Porsche introduced the Carrera 3.0 with wide rear flares, optional whale-tail, and other luxury options. Built before the ‘911 SC’ it has everything the SC has, and more. It’s a different drive with more power @200bhp; more torque @188 ft/lb @4200rpm and it was 10% lighter too.
The 911 SC effectively replaced the 911 S and was one of Porsche's first models that was meant for the international market. It was sold as a cheaper alternative to the 911 Turbo. The SC used an unblown version the 930 Turbo unit that offered 180 to 200 bhp depending on model year. Options included the rear whale tail, front chin spoiler, Bilstein dampers, 16 inch wheels with Pirelli P7 tires and sports seats. Sometimes dealers lumped these options together to create their own sport package. It was available as a Coupe and Targa from 1978 - 1983, while the Cabriolet version was only available in 1983.
The replacement for the SC series came in 1984 as the 911 3.2 Carrera, reviving the Carrera name for the first time since 1977. This was the last iteration in the original 911 series, with all subsequent models featuring new body styling and new brake, electronic, and suspension technologies. Almost the same galvanised body as the SC. Engine was claimed to be 80 per cent new, and the first production 911 to feature an ECU to control the ignition and fuel systems.
The 911 Turbo was put into production in 1975. While the original purpose of the 911 Turbo was to gain homologation for the 1976 racing season, it quickly became popular among car enthusiasts. Ernst Fuhrmann adapted the turbo-technology originally developed for the 917/30 CAN-AM car and applied it to the 3.0 litre flat-six used in the Carrera RS 3.0, thus creating what Porsche internally dubbed as the 930. Total power output from the engine was 260 bhp and 254 ft lbs of torque.
Porsche made its first and most significant changes to the 930 for 1978 model year, enlarging the engine bore by 2 mm (0.08 in) to a total displacement of 3,299 cc (3.3 L; 201.3 cu in) and adding an air-to-air intercooler. The suspension benefitted from new anti-roll bars, firmer shocks and larger diameter rear torsion bars. While the increase in displacement increased power output and torque, it also increased the weight of the vehicle, which contributed to a substantial change in the handling and character of the car compared to the Earlier 3.0-Litre Models.
Also produced for the 1976 "model year", for the U.S. market, was the 912E, a 4-cylinder version of the 911 like the 912 that had last been produced in 1969. It used the I-series chassis and the 2.0 Volkswagen engine from the Porsche 914. In all, 2092 units were produced. In 1976, the Porsche 924 took this car's place for the 1977 "model year" and beyond. The power was supplied by a 4-cylinder high-performance fuel injection motor also used in the Volkswagen 411.

2nd Gen Porsche 911 Special Models

There were several basic special edition models throughout the second generation 911s lifecycle that were nothing more than design exercises, but there were also some really interesting models too. Following the famous 1973 F-model 911 Carrera RS 2.7, Porsche built its successor based on the G-model and it was called the 911 Carrera RS 3.0. With its new 3.0-liter engine, featuring mechanical fuel injection, it was capable of 230 hp and boy, was it rare, with only 56 made. Then there was the Option M491 which was called the 'Supersport' in the UK, and commonly referred to as the 'Turbo-look'. The M491 option closely resembled the Model 930 Turbo with it's exterior styling that included flared wheel arches and the classic rear spoiler. It also featured wider wheels, a stiffer suspension and the superior turbo braking system. From August 1987 to September 1989 Porsche produced the model 911 Carrera Club Sport, or 911 Carrera CS. A total of 340 of these cars were built and they were built specifically for club racing and included a blueprinted engine with hollow intake valves, a higher rev limit, spartan interiors and zero power options - in an effort to save weight, of course. There was also the Speedster, a 2 seater, low-roof version of the Cabriolet, reminiscent of the model 356 Speedster of the 50's.

Following the famous 1973 F-model 911 Carrera RS 2.7, Porsche built its successor based on the G-model and it was called the 911 Carrera RS 3.0. With its 172 kW engine, it was the most powerful series production street-legal Porsche made so far. With its new 3.0-liter engine, featuring mechanical fuel injection, it was capable of 230 hp. While 1,580 Carrera RS 2.7s were built for 1973, only 56 Carrera RS 3.0s were built for 1974.
The first road-going 911 Turbo was not the familiar 930 that entered production in February 1975. Nor was it the engine-less prototype that had appeared at the Paris Motor Show in October 1973. Instead, it was a one-off narrow-bodied mule that was subsequently gifted to Ferry Porsche’s sister, Louise, on her 70th birthday in August 1974. Built on chassis 9115600042, this 2.7 Carrera Turbo also pre-dated the prototype 930 that was shown in almost production-ready at Frankfurt show in 1974.
1975 PORSCHE 911S SILVER ANNIVERSARY EDITION
Commemorating 25 years of Porsche sports car production, the 911S Silver Anniversary Edition is distinguished by unique Diamond Silver Metallic paint and a special black leatherette and tweed interior. The first of Porsche’s commemorative ‘celebration’ cars, this Silver Anniversary was produced in a limited run of 1,063 examples, of which approximately 500 are reported to have made their way to the United States.

1978 Porsche 911 SC Martini Edition
The 'Martini' edition of 1978, was identifiable by a set of side stripes similar to those that appeared on the 1976 British Motor Show 911 Turbo which was clad with the stripes to celebrate victories in the World Manufacturers Championship and the World Sports Car Championship, as well as the fourth consecutive racing season with sponsors Martini & Rossi. The stripes were so popular that Porsche quickly made them an option available to any owner as a factory or retro fit.
In 1980, a true limited edition model 911SC was produced for the American market. The 'Weissach' edition was a standard SC with special paint. It was built in 1980 to honor the Porsche Motorsport team working in Weissach Germany. 468 units were made and half were painted Metallic Black, the other half in Platinum Metallic. The interiors were wrapped in Doric Grey leather with burgundy piping. Additional body and mechanical specs included whale tail spoiler, Bilstein dampers and Fuchs wheels.
Slantnosed and based on that of the 935 racecars, with pop-up headlamps. The front spoiler was made deeper in order to accommodate the extra oil cooler, while intakes in the rear wings fed air to the brakes. The larger turbocharger and four-outlet exhaust gave 30bhp of extra power. Porsche began their “special order program” offering a Flachbau option (Slantnose) for the 930 in very limited production. All of this at a cost of nearly 2 times the standard 930S.
Finally, in 1982 the model 911 SP 'Ferry Porsche' was introduced as a special edition to celebrate 50 years of Porsche. This special edition was finished in Meteor metallic paint with burgundy leather interior and a 'Ferry Porsche' signature on the headrests. Only 200 of these now-classic special cars were built (130 Coupes and 70 Targas). The 911 SC “Jubilee” or “Ferry Porsche” is the first “limited series” sold in Europe.
Porsche introduced a new wide-body package option. Known as the M491 option it was commonly known as the "Turbo-Look". It gave the naturally aspirated cars the look and style of the 930 Turbo with wide wheel arches and the distinctive "tea tray" tail. It wasn't just about looks however, because M491 also got you the stiffer suspension shared with the Turbo and the superior Turbo braking system as well as the wider Turbo wheels. It was available on the Coupe, Cab and Targa.
The 911 Carrera Club Sport was Porsche refocusing on what they do best – high performance, lightweight motoring. This is probably the most underrated Porsche ever made. Manufactured between August 1987 and September 1989 only 340 cars. It had a blueprinted, high revving engine mated to a modified short-shift, close-ratio G50 gearbox. It had track-bias suspension modifications too.
Just 50 ‘C16’ cars were manufactured for the UK-market, initially equipped with an uprated engine of 330bhp (from 300) mated to a 4-speed transmission. However, at the end of 1988, the uprated 5-Speed G50 gearbox was introduced, dramatically easing the peaks in power delivery by reducing the effects of ‘turbo-lag’. The factory SE also benefited from a dual-exit exhaust system, limited-slip differential, heated front seats and a sunroof.
In 1988, Porsche produced 875 examples of the CE or Commemorative Edition 911 Carrera in coupe, targa and cabriolet variants to mark the production of the 250,000th 911. Distinguishing features include special diamond blue metallic paint with color-matched Fuchs wheels, front and rear spoilers, and interior carpets and leather. These cars also featured Dr. Ferdinand Porsche's signature embroidered on the seats in the headrest area.
Only 50 units made. The 911 Turbo Limited Edition comes equipped with the 330 bhp power unit normally only available in the 911 Turbo with Sport Equipment. In addition, the fitment of a limited slip differential as standard ensures the the increased engine performance can be used to it’s fullest extent. This Limited Edition also adopts the rear wheel air intakes of the Sport Equipment version. Essentially an SE without a slantnose front.
Essentially a Carrera 3.2 with a chopped, more steeply raked windscreen and hood, plus a stripped-out interior. Most had wide Turbo bodies. Porsche insisted that the simple hood was not designed to be 100 per cent watertight. The first Porsche 911 Speedster was built in 1989 and it was the last vehicle with the old 911 body. Three decades passed before the Speedster made a comeback. Had a 3.2 L Aircooled Flat 6 and 2274 were produced for the 1989 model year.
For 1989, Porsche produced the 25th Anniversary Special Edition model to mark the 25th year of 911 production. The 1989 Porsche brochure lists production of 500 U.S. market cars, of which 300 were coupés (240 in silver metallic paint and 60 in satin black metallic), and 200 cabriolet models (160 in silver and 40 in black). All had "silk grey" leather with black accent piping and silk grey velour carpeting. Includes small bronze "25th Anniversary Special Edition" badges.

2nd Gen Porsche 911 Race & Motorsport Models

This was one hell of an era for Porsche 911 race based cars. For 1974 both the 911 Carrera RSR 3.0 and RSR Turbo 2.1 were created - the 3.0L for the customer teams and the 2.1 turbo for Porsche’s own team. The 911 Carrera Turbo 2.1 was the first turbocharged Porsche 911, and the first turbo-powered Porsche race car at Le Mans. It was fitted with a newly-developed 2,142 cc engine which was good for 500 bhp. The 3.0 RSR was an amazing car to drive and it went on to become one of the most successful Group 4 racing cars ever. The Carrera RSR 3.0 was made in small numbers for racing. For the privateer in the mid-1970s who wanted to go sports car racing, and in particular compete successfully at the famed 24 Hours of Le Mans, there was really only one viable option, the Porsche RSR. Introduced in 1973, the 2.8 RSR was a factory-built racing car based on the 911 chassis. These were not converted street cars, but rather purpose built competition models designed and built from the ground up for serious racing use. The 3.0 RSR had the perfect combination of low weight, immense Porsche 917 brakes, impeccable handling, and a 330+hp naturally aspirated flat-6 that gave the model a mighty power-to-weight ratio. This era also gave us some great Porsche 911 rally cars too, which we have included below.

For 1974 both the 911 Carrera RSR 3.0 and RSR Turbo 2.1 were created - the 3.0L for the customer teams and the 2.1 turbo for Porsche’s own team. The 911 Carrera RSR Turbo 2.1 developed 338-368 kW in power, but as the engine was small, the turbo lag was big and it wasn’t as easy to drive out of the corners as it was with the 3-litre normally aspirated car. Weight reduction measures included plastic hoods, fender flares and doors and an aluminium safety cage.
Porsche-911-Carrera-RSR-3.0
For the 1974 racing season 911 Carrera RSR 3.0 (246 kW) and RSR Turbo 2.1 (338+ kW) were created - the 3.0L for the customer teams and the 2.1 turbo for Porsche’s own team. The Carrera RSR 3.0 was made in small numbers for racing. The 3.0 RSR would go on to become the most successful Group 4 racing car of its time thanks to its combination of low weight, immense Porsche 917 brakes, impeccable handling, and a 330+hp naturally aspirated flat-6.
In 1978, the works team fields two 911 SC at the East African Safari Rally. The name of game is to survive 5,000 kilometres of the toughest tracks in sweltering heat and torrential rain. The conditions take their toll: of the 72 starters, 13 reach the finish line. Martini Racing Porsche System Engineering signs on two specialists to drive: Sweden’s Björn Waldegård (Start No. 5) and Kenyan Vic Preston Jnr (Start No. 14).
Röhrl and Geistdörfer very nearly won that San Remo Rally, after a comeback that would have been one for the ages. Röhrl and Geistdörfer were up against a field of faster, more powerful four-wheel-drive cars in their rear-wheel-drive Porsche 911 SC, and somehow managed to pull within an eyelash of victory. Unfortunately, a broken driveshaft forced the pair to retire, leaving Michele Mouton's Audi Quattro to run away with the race.
Built so that the factory Rothmans Porsche Rally Team could hit the international stage, the SC RS used the Turbo’s body with fibreglass bumpers and aluminium doors. In Autumn 1983, Porsche presents the 911 SC/RS for motor racing. The engine originates from the 911 SC, with improved performance achieved by the mechanical ball fuel injection, increased compression, the cylinder heads from the 935 and forged pistons. Racing seats are fitted in place of the standard seats.
The Porsche 953 ranks as one of the finest off-roaders Porsche has ever made. It was basically a souped-up 911 designed specially to give Porsche an advantage in the 1984 Paris–Dakar Rally. Just a year later, it was replaced by the 959. Despite its brief run, it still managed to make quite the impression. Built around a massively enhanced suspension and a supremely powerful 300 bhp (224 kW), 6-cylinder engine, it showed Porsche knew more than just sportscars.
