The Porsche 930 is a turbocharged variant of the 911 model sports car manufactured by German automobile manufacturer Porsche between 1975 and 1989. It was the maker's top-of-the-range 911 model for its entire production duration and, at the time of its introduction, was the fastest production car available in Germany.[3][4][5]
Porsche began experimenting with turbocharging technology on their race cars during the late 1960s, and in 1972 began development on a turbocharged version of the 911. Porsche originally needed to produce the car in order to comply with homologation regulations and had intended on marketing it as a street legal race vehicle like the 1973 Carrera 2.7 RS. The FIA's Appendix "J” rules upon which the 911 Turbo Carrera RSR 2.1 was entered into competition in 1974 changed in 1975 and 1976. The FIA announced that cars for Group 4 and Group 5 had to be production cars and be available for sale to individual purchasers through manufacturer dealer networks. For the 1976 season, new FIA regulations required manufacturers to produce 400 cars within a twenty-four-month period to gain approval for Group 4. Group 5 would require the car to be derived from a homologated model in Group 3 or 4. Porsche's Group 4 entry was the 934, homologated on 6 December 1975. For Group 5, Porsche would develop one of the most successful racing cars of the time, the 935. 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. Four hundred cars were produced by the end of 1975.[citation needed] Since Porsche wanted to compete in the 1976 season, they gained FIA homologation for the Porsche Turbo for Group 4 in Nr. 645 on 6 December 1975 and the 1,000th 911 Turbo was completed on 5 May 1976.
Porsche 930 Turbo No. 1
Ferry Porsche gave the first Turbo model to his sister Louise Piëch for her 70th birthday. Although this 911 Turbo No. 1 already has the large rear spoiler of the later production model, it still has the narrower bodywork of the Carrera, whose lettering at the rear has not been removed. In addition, the 911 Turbo No. 1 has only a turbocharged 2.7-liter boxer engine with 177 kW (240 hp) instead of the 3.0-liter boxer engine installed later.[6]
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 Carrera RS 3.0, thus creating what Porsche internally dubbed as the 930. The car utilises a single KK&K turbocharger.[7]
Total power output from the engine was 260PS (191kW; 256hp) at 5,500 rpm and 329N⋅m (243lb⋅ft) of torque at 4,000 rpm, much more than the standard Carrera it was based on. The engine has a compression ratio of 6.5:1. In order to ensure that the platform could make the most of the higher power output, a revised suspension, larger brakes and a stronger gearbox became part of the package, although some consumers were unhappy with Porsche's use of a four-speed transmission whilst a five-speed manual transmission was available in the "lower trim" Carrera. A "whale tail" rear spoiler was installed to help vent more air to the engine and to create more downforce at the rear of the vehicle, and wider rear wheels with upgraded tires combined with flared wheel arches were implemented in order to increase the car's width and grip, making it more stable.
Early US-spec 930 with "Turbo Carrera" badgingPorsche 911 (930) Turbo
Porsche badged the vehicle simply as "Turbo" (although early U.S. units were badged as "Turbo Carrera") and introduced the vehicle at the Paris Auto Show in October 1974 before putting it on sale in the spring of 1975; export to the United States began in 1976.
The 930 proved very fast but also very demanding to drive, and due to its short wheelbase and rear engine layout, was prone to oversteer and turbo-lag. It acquired the nickname "the Widowmaker" after several crashes and deaths attributed to its handling characteristics, which were unfamiliar to many drivers. Under certain conditions, applying too much throttle would cause the heavy rear end of the car to swing outward like a pendulum, causing the car to spin out. To this day, Porsche corporate employees who drive 911 Turbo models for testing or for business reasons are mandated to undergo "Turbo Training", despite the fact that newer 911 Turbo models are generally safer and easier to drive. [citation needed]
Porsche made its first and most significant changes to the 930 for 1978 model year, enlarging the engine bore by 2mm (0.08in) to a total displacement of 3,299cc (3.3L; 201.3cuin) and adding an air-to-air intercooler. By cooling the pressurised air charge, the intercooler helped increase power output to 300PS (221kW; 296hp) at 5,500 rpm and 412N⋅m (304lb⋅ft) of torque at 4,000 rpm (DIN); the rear 'whale tail' spoiler was re-profiled and raised slightly to make room for the intercooler and the spoiler was now infamously called the 'tea tray' spoiler by the enthusiasts. The suspension benefitted from new anti-roll bars, firmer shock absorbers and larger diameter rear torsion bars. Porsche also upgraded the brakes to units similar to those used on the 917 race car. While the increase in displacement and addition of an intercooler increased power output and torque, these changes also increased the weight of the vehicle, especially the engine, which contributed to a substantial change in the handling and character of the car compared to the earlier 3.0-litre models.
Changing emissions regulations in Japan and the United States forced Porsche to withdraw the 930 from those markets in 1980. It however remained available in Canada. Envisioning the luxurious 928gran turismo eventually replacing the 911 as the top of the Porsche model lineup, Fuhrmann cut back further development on the model, and it was not until his resignation that the company finally committed the financing to update the car's emissions systems, and recertify the 930 for sale in all markets.
The 930 remained available in Europe, and for 1983 a 330PS (243kW; 325hp) at 5750 rpm and 432N⋅m (319lb⋅ft) of torque at 4000 rpm[8] performance option became available on a build-to-order basis from Porsche. With the so-called Werksleistungssteigerung (WLS, "Works Performance Increase") add-on came a quad-pipe exhaust system and an additional oil-cooler requiring a remodelled front spoiler and units bearing the add-on often featured additional ventilation holes in the rear fenders and modified rockers.
By the 1985 model year, 928 sales had risen slightly, but the question remained as to whether it would supersede the 911 as the company's premier model. Porsche reintroduced the 930 to the Japanese and U.S. markets in 1986 with an emission-controlled engine having a power output of 282hp (210kW; 286PS) at 5500 rpm and 377N⋅m (278lb⋅ft) at 4000 rpm of torque.[9] At the same time Porsche introduced targa and cabriolet variants, both of which proved popular.
Porsche discontinued the 930 after the 1989 model year when its underlying "G-Series" platform was being replaced by the 964. The 1989 models were the first and last versions of the 930 to feature the Getrag G50 five-speed manual transmission. A turbocharged variant of the 964 officially succeeded the 930 in 1991 with a modified version of the same 3.3-litre flat-six engine and a five-speed transmission.
Flatnose (Slantnose 930S)
1988 factory 930 Cabriolet flatnose
Kremer Racing had originally begun offering conversion kits for 930 Turbo models which included front bodywork like the famous 935 race car in 1981.[10] In 1982, TAG Heuer co-owner Mansour Ojjeh commissioned Porsche to develop a road-legal version of the 935 race car. The final product was developed using a body shell of the 930 and fitting fabricated 935 body panels to it. The one-off also had the suspension and brakes shared with the 935 race car. Other special features of the car included special paintwork called Brilliant Red by the manufacturer, BBS wheels and the use of the 3.3-litre turbocharged flat-6 engine of the 934 race car. The car proved very popular among enthusiasts and prospective buyers began to demand a similar car as a factory offering. Porsche offered a "Flachbau" ("flatnose" or "slantnose") 930 under the "Sonderwunschprogramm" (special order program) from 1986 model year, an otherwise normal 930 with a 935-style slantnose instead of the normal 911 front end with the replacement of the famous "bug eye" headlamps with pop-up units.[11]
Each Flachbau unit was handcrafted by remodeling the front fenders (option code M505 for the US and M506 elsewhere). A limited number of units were produced due to the fact that the package commanded a high premium price, an initial premium of up to 60 per cent (highly individualised cars requiring even more) over the standard price. 948 units were built in total with 160 of them being imported to the US. The Flachbau units delivered in Europe usually featured the 330PS (243kW; 325hp) WLS performance kit. The flat nose greatly contributed to the aerodynamics of the car and enabled it to accelerate from 0–97km/h in 4.85 seconds and attain a top speed of 278km/h (173mph) (figures with the performance kit).[12][13]
Car and Driver recorded a 0–60mph acceleration time of 4.9 seconds for both the 1975 and 1978 Porsche 911 Turbo, they shared first place in the magazine's "quickest cars of the 1970s" ranking with a 0.4-second lead.[21]
TAG Turbo
Porsche 930 TAG Turbo
In the 1980s, Porsche built twin-turbocharged 1.5-litre V6 engines for the McLaren Formula One team. The engine was given the code TTE P01 and was fitted in the McLaren MP4/2 and MP4/3 generating 760–1,014PS (559–746kW; 750–1,000hp) depending on track conditions. The engine was financed by Luxembourgian holdings company Techniques d'Avant Garde (TAG), leading to the engine being branded as the TAG Turbo. A Porsche 930 Turbo was used as a test mule by McLaren in order to test the engine's capability. The car was exterior-wise similar to the standard 930 Turbo but featured RUF sourced wheels instead of the standard Fuchs units, a taller whale tail rear spoiler in order to accommodate a large pair of intercoolers and a new front bumper. The changes to the interior consisted of racing bucket seats and a new TAG branded tachometer with a 10,000 rpm redline.
In September 2018, English automotive company Lanzante introduced a new model based on the same principle at the RennSport Reunion VI. The company obtained permission from McLaren to produce the model and bought 11 of those engines originally installed in the F1 cars for this purpose from the manufacturer. Cosworth is tasked to restore the engines. Each of the 11 cars fitted with the engines would come with a plaque signifying the engine's race history, engine number and the car's production number. The Lanzante display car's engine was originally fitted in 1984 to Niki Lauda's MP4/2 in which he won the British GP.[22][23][24]

The Porsche 924 is a sports car produced by Porsche in Neckarsulm, Germany, from 1976 until 1988. A two-door, 2+2 coupé, the 924 replaced the 912E and 914 as the company's entry-level model.
The Porsche Carrera GT is a mid-engine sports car that was manufactured by German automobile manufacturer Porsche from 2004 to 2006. Sports Car International named the Carrera GT number one on its list of Top Sports Cars of the 2000s, and number eight on its Top Sports Cars of All Time list. For its advanced technology and development of its chassis, Popular Science magazine awarded it the "Best of What's New" award in 2003.
The Porsche 993 is the fourth generation of the Porsche 911 model sports car manufactured and sold between January 1994 and early 1998, replacing the 964. Its discontinuation marked the end of air-cooled 911 models.
The Porsche 996 is the fifth generation of the 911 model sports car manufactured by the German automaker Porsche from 1997 until 2006. It was replaced by the 997 in 2004, but the high performance Turbo S, GT2 and GT3 variants remained in production until 2006. The 996 had little in common with its predecessor, with the first all new chassis platform since the original 911 and a new water-cooled engine. Technically, it was a major change, a complete break from the original car other than the overall layout.
The Porsche 997 is the sixth generation of the Porsche 911 sports car manufactured and sold by the German automobile manufacturer Porsche between 2004 and 2013. Production of the Carrera and Carrera S coupés began in early 2004, all-wheel drive Carrera 4 and Carrera 4S began to be delivered to customers in November 2005, the Turbo and GT3 derivatives went on sale in late 2006 and the GT2 in 2007. In addition to the coupé and cabriolet versions, Targa versions of the Carrera 4 and Carrera 4S were also available, which carry on with the "glass canopy" roof design used since its first application on the 993 until the 991, which reverted to the classic targa top layout used on the early 911 Targas.
The Porsche 964 is a model of the Porsche 911 sports car manufactured and sold between 1989 and 1994. Designed by Benjamin Dimson through January 1986, it featured significant styling revisions over previous 911 models, most prominently the more integrated bumpers. It was the first car to be offered with Porsche's Tiptronic automatic transmission and all wheel drive as options.
The Porsche 935 is a race car that was developed and manufactured by German automaker Porsche. Introduced in 1976 as the factory racing version of the 911 (930) Turbo and prepared for FIA-Group 5 rules, it was an evolution of the Carrera RSR 2.1 turbo prototype, the second place overall finisher in the 1974 24 Hours of Le Mans.
The Ruf CTR2 is a 2-door sports car built by German automobile manufacturer Ruf Automobile from 1995 to 1997 as the successor to the CTR Yellowbird, but based on Porsche's Type 993 generation 911.
The Porsche 911 GT3 is a high-performance homologation model of the Porsche 911 sports car. It is a line of high-performance models, which began with the 1973 911 Carrera RS. The GT3 has had a successful racing career in the one-make national and regional Porsche Carrera Cup and GT3 Cup Challenge series, as well as the international Porsche Supercup supporting the FIA F1 World Championship.
The Ruf CTR also known as the CTR Yellowbird or simply Yellowbird, is a limited-production, high performance sports car manufactured by German automobile manufacturer Ruf Automobile. Introduced for the 1987 model year and based on the Porsche 911, the CTR featured an enlarged and highly tuned version of Porsche's 3.2 litre flat-six cylinder engine, lightened body panels, an integrated roll cage, upgraded suspension and braking systems, a custom-designed transmission, and several unique trim pieces such as polyurethane bumpers, and the use of the side-mounted oil filler necessitated by relocating the oil tank forward to clear the intercooler on that side.
The Porsche 911 GT2 is a high-performance, track-focused sports car built by the German automobile manufacturer Porsche from 1993 to 2009, and then since 2010 as the GT2 RS. It is based on the 911 Turbo, and uses a similar twin-turbocharged engine, but features numerous upgrades, including engine enhancements, larger brakes, and stiffer suspension calibration. The GT2 is significantly lighter than the Turbo due to its use of rear-wheel-drive instead of all-wheel-drive system and the reduction or removal of interior components. As a result, the GT2 is the most expensive and fastest model among the 911 lineup.
The Ruf BTR is a sports car built by German automobile manufacturer Ruf Automobile. The BTR began production in 1983 and was based on the Porsche 911 available in a narrow 911 or optional wide body configuration akin to the 930 Turbo. The BTR was the first Ruf production sports car with a company specific VIN.
The original Porsche 911 is a luxury sports car made by Porsche AG of Stuttgart, Germany. A prototype of the famous, distinctive, and durable design was shown to the public in autumn 1963. Production began in September 1964 and continued through 1989. It was succeeded by a modified version, internally referred to as Porsche 964 but still sold as Porsche 911, as are current models.
The Porsche 991 is the seventh generation of the Porsche 911 sports car, which was unveiled at the 2011 Frankfurt Motor Show on 15 September as the replacement for the 997. The 991 was an entirely new platform, only the third since the original 911 launched in 1963. Production of the 991 generation ended on December 20, 2019, with 233,540 units produced.
The Porsche 911 is a two-door 2+2 high performance rear-engined sports car introduced in September 1964 by Porsche AG of Stuttgart, Germany. It has a rear-mounted flat-six engine and originally a torsion bar suspension. The car has been continuously enhanced through the years but the basic concept has remained unchanged. The engines were air-cooled until the introduction of the 996 series in 1998.
The Porsche 982 is the internal designation of the fourth generation Boxster/Cayman made by German automobile manufacturer Porsche. With the switch to a new turbocharged flat-four engine the marketing name for the models was changed to Porsche 718, in reference to the 718, which won the Targa Florio race in 1959 and 1960. The name is meant to evoke Porsche's past racing successes with light cars like the 718 that outmanoeuvred competitors with larger and more powerful engines.
The Porsche 992 is the eighth and current generation of the Porsche 911 sports car, which was introduced at the Porsche Experience Center in Los Angeles on 27 November 2018.
The Ruf BTR2 is a sports car produced by Ruf Automobile. Based on the Porsche 993 Carrera, it succeeded the original BTR. The BTR2 was among the fastest road cars of its time, attaining a top speed of 308 km/h (191 mph).
The Ruf SCR is a sports car manufactured by German automobile manufacturer Ruf Automobile. The SCR was based on the Porsche 911 SC and the changes made to its engine enabled it to have similar performance to the 930 Turbo, despite having a naturally aspirated engine.
The Porsche Supercup is an international one-make production stock car racing series supporting the FIA Formula One World Championship organized by Porsche Motorsport GmbH.
