Porsche 911



Generation 1



The earliest editions of the 911 had a 130 PS (96 kW) flat-6 engine, in the "boxer" configuration like the 356, air-cooled and rear-mounted, displaced 1991 cm³ (cc) compared with the 356's four-cylinder, 1600 cc unit. The car had four seats although the rear seats are very small, and the car is usually called a 2+2 rather than a four-seater (the 356 was also a 2+2). It was mated to a five-speed manual "Type 901" transmission. The styling was largely by Ferdinand "Butzi" Porsche, son of Ferdinand "Ferry" Porsche. Erwin Komenda, the leader of the Porsche car body construction department, was also involved in the design.

The 356 came to the end of its production life in 1965, but there was still a market for a 4-cylinder car, particularly in the USA. The Porsche 912, introduced the same year, served as a direct replacement. It used the 356's 4-cylinder, 1600 cc, 90 hp (67 kW) engine but wore the 911 bodywork.

In 1966 Porsche introduced the more powerful 911S, the engine's power raised to 160 PS (120 kW; 160 hp). Alloy wheels from Fuchs, in a distinctive 5-leaf design, were offered for the first time. In motorsport at the same time, installed in the mid-engined Porsche 904 and Porsche 906, the engine was developed to 210 PS (154 kW).

In 1967 the Targa version was introduced as a "stop gap" model. The Targa had a stainless steel-clad roll bar, as Porsche had, at one point, thought that the National Highway Traffic Safety Administration (NHTSA) would outlaw fully open convertibles in the US, an important market for the 911. The name "Targa" (which means "shield" in Italian) came from the Targa Florio sports car road race in Sicily, Italy in which Porsche had notable success, with seven victories since 1956, and four more to come until 1973. This last win in the subsequently discontinued event is especially notable as it was scored with a 911 Carrera RS against prototypes entered by Italian factories of Ferrari and Alfa Romeo. The road going Targa was equipped with a removable roof panel and a removable plastic rear window (although a fixed glass version was offered alongside from 1968).

The 110 PS (81 kW; 110 hp) 911T was also launched in 1967 and effectively replaced the 912. The staple 130 PS (96 kW; 130 hp) model was renamed the 911L. The 911R had a very limited production (20 in all). This was a lightweight racing version with thin aluminium doors, a magnesium crankcase, twin-spark cylinder heads, and a power output of 210 PS (150 kW; 210 hp).

In 1969 the B series was introduced: the wheelbase for all 911 and 912 models was increased from 2,211 to 2,268 millimetres (87.0 to 89.3 in), an effective remedy to the car's nervous handling at the limit. The overall length of the car did not change: rather, the rear wheels were relocated aft. Fuel injection arrived for the 911S and for a new middle model, 911E. A semi-automatic Sportomatic model, composed of a torque converter, an automatic clutch, and the four-speed transmission, was added to the product lineup.

The B17 (1969) is a concept designed by Pininfarina by lengthening the wheelbase by 7.5 in (190 mm), resulting in a car 2,500 lb (1,100 kg) heavier than original.

For MY 1970 the engines of all 911s were increased to 2,195 cc (2.195 L; 133.9 cu in). Power outputs were uprated to 125 PS (92 kW; 123 hp) in the 911T, 155 PS (114 kW; 153 hp) in the 911E, and 180 PS (130 kW; 180 hp) in the 911S. The 912 was discontinued, thanks to the introduction of the Porsche 911T as an entry model.

The 2.2 L 911E was called "The secret weapon from Zuffenhausen". Despite the lower power output of the 911E compared to the 911S, the 911E was quicker in acceleration up to 160 km/h (99 mph).

The C 20 (1970) is a prototype extended by 13.6 in (345 mm) over stock car, with 911S engine.

The 1972–1973 model years consisted of the same models of 911— the entry level T, the midrange E and the top of the line S. However, all models got a new, larger 2,341 cc (2.341 L; 142.9 cu in) engine. This is universally known as the "2.4L" engine, despite its displacement being closer to 2.3 litres— perhaps to emphasize the increase over the 2.2 L. The new power ratings were 130 hp (97 kW), or 140 hp (104 kW) in the U.S., for the T, 165 hp (123 kW) for the E and 190 hp (142 kW) for the S.

The 911E and 911S used mechanical fuel injection (MFI) in all markets. The 911T was carbureted, except in the US where it also used MFI, which accounts for the 7 kW (9 hp) power difference between the two. In January, 1973, US 911Ts were switched to the new K-Jetronic CIS (Continuous Fuel Injection) system from Bosch. These CIS-powered cars are usually referred to as "1973.5" models by enthusiasts.

With the power and torque increases, the 2.4 L cars also got a newer, stronger transmission, identified by its Porsche type number 915. Derived from the transmission in the Porsche 908 race car, the 915 did away with the 901/911 transmission's "dog-leg" style first gear arrangement, opting for a traditional H pattern with first gear up to the left, second gear underneath first, etc. Some say this was because the dog-leg shift to second gear was inconvenient for city driving, other say it was due to Porsche’s desire to put 5th gear outside the main transmission housing where it could easily be changed for different races. The Sportomatic transmission was still available but only as a special order.

In 1972 a tremendous effort was made to improve the handling of the 911. Due to the 911's unusual engine placement (rear-mounted, with most of the vehicle's weight concentrated over the rear axle) early 911's were prone to oversteer when driven at the limit, and could easily spin in the hands of an inexperienced driver. In an attempt to remedy this, Porsche relocated the oil tank from its position behind the right rear wheel to in front of it. This had the effect of moving the weight of almost 9 quarts (8.5 L) of oil from outside the wheelbase to inside, improving weight distribution and thus, handling. To facilitate filling of the oil tank, Porsche installed an oil filler door (much like the fuel filler door on the left front fender) on the right rear quarter panel. Unfortunately, this unique design was scrapped after only one year, some say because inattentive gas station attendants were putting gas in the oil tank. The oil tank was subsequently moved back to its original position for model year 1973, and remained there until it was moved back within the wheelbase for the 964 models.

911S models also gained a discreet spoiler under the front bumper to improve high-speed stability. With the car's weight only 1050 kg (2315 lb), these are often regarded as the best classic mainstream 911s. For racing at this time, the 911 ST was produced in limited numbers (the production run for the ST only lasted from 1970 to 1971.) The cars were available with engines of either 2466 cc or 2492 cc, producing 270 PS (199 kW) at 8000 rpm. Weight was down to 960 kg (2166 lb). The cars had success at the Daytona 6 Hours, the Sebring 12 Hours, the 1000 km Nürburgring and the Targa Florio.

The Carrera RS (1973 and 1974), valued by collectors, are considered by many to be the greatest classic 911s all-time. RS stands for Rennsport in German, meaning "racing sport". The Carrera name was reintroduced from the 356 Carrera which had itself been named after Porsche's victories in the Carrera Panamericana races in Mexico in the 1950s. The RS was built so that Porsche could enter racing formulae that demanded that a certain minimum number of production cars were made. Compared with a standard 911S, the Carrera 2.7 RS had a larger engine (2687 cc) developing 210 PS (150 kW; 210 hp) with MFI, revised and stiffened suspension, a "ducktail" rear spoiler, larger brakes, wider rear wheels and rear wings. In RS Touring form it weighed 1075 kg (2370 lb), in Sport Lightweight form it was about 100 kg (220 lb) lighter, the saving coming from the thin-gauge steel used for parts of the bodyshell and also the use of thinner glass. In total, 1580 were made, comfortably exceeding the 500 that had to be made to qualify for the vital FIA Group 4 class. 49 Carrera RS cars were built with 2808 cc engines producing 300 PS (221 kW).

In 1974, Porsche created the Carrera RS 3.0 with K-Jetronic Bosch fuel injection producing 230 PS (169 kW).It was almost twice as expensive as the 2.7 RS but offered a fair amount of racing capability for that price. The chassis was largely similar to that of the 1973 Carrera RSR and the brake system was from the Porsche 917. The use of thin metal plate panels and a spartan interior enabled the shipping weight to be reduced to around 900 kg (1984 lb).

The Carrera RSR 3.0 and Carrera RSR Turbo (its 2.1 L engine due to a 1.4x equivalency formula) were made in tiny numbers for racing. The turbo car came second at the 24 Hours of Le Mans in 1974, a significant event in that its engine would form the basis of many future Porsche attempts in sportscar racing, and can be regarded as the start of its commitment to turbocharging.
