127-634: The Triumph TR4 is a sports car produced by the Triumph Motor Company from 1961 to 1965. Successor to the TR3A , the TR4's chassis and drivetrain are closely related to those of its predecessor, but with an updated body designed by Michelotti . Triumph began planning a successor to the TR3 as early as 1956. At the time, the company was facing a number of challenges. Lack of capital to fund development

254-405: A 3.2-litre horizontally opposed flat 6-cylinder unit, was utilized. At the time Porsche claimed it was 80% new. The new swept volume of 3,164 cc was achieved using the 95 mm (3.7 in) bore (from the previous SC model) combined with the 1978 Turbo 3.3 crankshaft's 74.4 mm (2.9 in) stroke. In addition, higher domed pistons increased the compression ratio from 9.8 to 10.3:1 (9.5:1 for

381-557: A 5-speed 915 transmission. Originally power output was 180 PS (132 kW; 178 hp), later 191 PS (140 kW; 188 hp) and then in 1981 it was increased to 204 PS (150 kW; 201 hp). The move to an aluminium engine was to regain case reliability, something missing for many years with magnesium. In 1981 a Cabriolet concept car was introduced at the Frankfurt Motor Show . The convertible body design also featured four-wheel drive , although this

508-544: A 7-year run from 1975–1981. As of Q2 2022 there were approximately 953 licensed and 216 SORN TR4s registered with the DVLA . The TR4 had a number of racing successes in America, primarily through the efforts of Californian engineer Kas Kastner and his top driver, Bob Tullius . In 1961 the TR4 with commission number CT 7L, driven by George Waltman and Nick Cone, won first in class and thirtieth overall at Sebring . In 1962

635-403: A 911T/E. With power and torque increase, the 2.4-litre cars also got a newer, stronger transmission, identified by its Porsche type number 915. Derived from the transmission in the 908 race car, the 915 did away with the 901 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. The E series had

762-492: A K-Jetronic 2.7-litre. The 911S 2.7 engine was rated during the entire lifespan at 175 hp (130 kW; 177 PS). The Carrera 2.7 model built for all markets, except for the United States, used the 210 PS (150 kW; 210 hp) RS 911/83 engine with Bosch mechanical fuel injection pump from the 1973 Carrera RS. These Carrera 2.7 MFI models were built from 1974 until 1976 and were mechanically identical to

889-618: A TR4A-based version. The aerodynamics of the Dové gave it good acceleration from 80 to 100 mph (130 to 160 km/h) in comparison with the TR4 drophead coupé. One example was exported for sale through Australian Motor Industries in Melbourne, Australia. A road test of one of these cars was reported in Autocar magazine dated 7 June 1963, and in Autosport magazine on 12 July 1963. Up to

1016-409: A chart on the wall of Professor Bott's office. It depicted the ongoing development schedules for the three primary Porsche product lines: 944 , 928 and 911. Two of them stretched far into the future, but the 911 program stopped at the end of 1981. I remember rising from my chair, walking over to the chart, taking a black marker pen, and extending the 911 program bar clean off the chart. I am sure I heard

1143-399: A controversial choice for a "purist" sports car. The Elan sold poorly and was discontinued after three years. The 1996 Lotus Elise , a mid-engined, rear-wheel drive roadster, was much more successful and remained in production until 2021. Roadsters enjoyed a resurgence in the mid-1990s, including the 1989-present Mazda MX-5 , the 1995-2002 BMW Z3 (succeeded by the 2002-2016 BMW Z4 ),

1270-409: A definition. Insurance companies have also attempted to use mathematical formulae to categorise sports cars, often charging more for insurance due to the inherent risk of performance driving. There is no fixed distinction between sports cars and other categories of performance cars, such as muscle cars and grand tourers , with some cars being members of several categories. Traditionally,

1397-505: A detachable centre panel made of aluminium on the first 500 units, and steel on subsequent cars. Featured on one of the Zoom prototypes, this was the first such roof system on a production car, predating the Porsche 911 / 912 Targa by five years. On the TR4 the rigid roof panel could be replaced with a vinyl insert and supporting frame. While the rigid panel could not be stowed in the car,

1524-674: A different name in France, Porsche changed the name to 911. Internally, the cars' part numbers carried on the prefix 901 for years. Production began in September 1964, with the first 911s exported to the US in February 1965. The first models of the 911 had a rear-mounted 130 hp (97 kW) Type 901/01 flat-6 engine, in the " boxer " configuration like the 356, the engine is air-cooled and displaces 1,991 cc (2.0 L) as compared to

1651-476: A dozen of the cars are known to still exist. Sports car A sports car is a type of car that is designed with an emphasis on dynamic performance, such as handling , acceleration, top speed, the thrill of driving, and racing capability. Sports cars originated in Europe in the early 1910s and are currently produced by many manufacturers around the world. Definitions of sports cars often relate to how

1778-469: A flat top edge to fit the new roof line. Some were fitted with a fully balanced motor built by either Jack Brabham Motors or Laystall Engineering in London, which was offered as an option in the sales catalogue. Each Dové was an individual order, with some variations between each car. The cars were priced at an expensive £1250. Although most Dovés were based on the TR4 model, some brochures include pictures of

1905-506: A larger engine (2,687 cc) developing 210 PS (154 kW; 207 hp) with Bosch ( Kugelfischer ) mechanical fuel injection, revised and stiffened suspension, a "ducktail" rear spoiler, larger brakes, wider rear wheels and rear fenders, to fit 185/70VR15 and 215/60VR15 tyres front and rear. In RS Touring form it weighed 1,075 kg (2,370 lb), in Sport Lightweight form it was about 100 kg (220 lb) lighter,

2032-460: A limited production (20 in all), as this was a lightweight racing version with thin fiberglass reinforced plastic doors, a magnesium crankcase, twin overhead camshafts, and a power output of 210 PS (154 kW; 207 hp). A clutchless semi-automatic Sportomatic model, composed of a torque converter , an automatic clutch , and the four-speed transmission was added in Autumn 1967. It

2159-531: A notchback design with proper space for seating two rear passengers but Ferry Porsche insisted that the 356's successor was to use its fastback styling. 7 prototypes were built based on Butzi Porsche's original design and were internally called the Porsche 754 T7. Erwin Komenda , the leader of the Porsche car body construction department who initially objected, was also involved later in the design. Production of

2286-399: A pressed-steel chassis, a gated 4-speed transmission, pushrod-actuated overhead inlet valves , a honeycomb radiator, low-tension magneto ignition , a long wheelbase, a low center of mass and a very effective suspension system. The overall result was a "safe and well-balanced machine" with a higher performance than any other contemporary production car. At the 1903 Gordon Bennett Cup ,

2413-427: A production Simplex 60 hp was entered only due to a specially-built 90 hp racing car being destroyed in a fire; the 60 hp famously went on to win the race. The 1910 Austro-Daimler 27/80 is another early sports car which had success in motor racing. The 27/80 was designed by Ferdinand Porsche , who drove the car to victory in the 1910 Prince Henry Tour motor race. The Vauxhall and Austro-Daimler —like

2540-419: A removable roof panel. The Zoom body was used for the three Triumph TRS race cars fielded at the 1960 24 Hours of Le Mans , which were powered by three 20X DOHC engines. The cars staged a formation finish, but were unclassified due to having failed to cover their mandatory distance. The cars were revised and entered again in the 1961 race, where they finished ninth, eleventh, and fifteenth overall, and claimed

2667-784: A significant event in that its engine would form the basis of many future Porsche attempts in sports car racing. This, and the earlier 917, was Porsche's commitment to turbocharger applications in its cars. 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. Model year 1974 (G Series. Aug. 1973 to July 1974 production) Model year 1975 (H Series. Aug. 1974 to July 1975 production) Model year 1976 (J Series. Aug. 1975 to July 1976 production) Model year 1977 (K Series. Aug. 1976 to July 1977 production) The 1974 model year brought many significant changes to

2794-605: A silent cheer from Professor Bott, and I knew I had done the right thing. The Porsche 911, the company icon, had been saved, and I believe the company was saved with it. 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. A new higher-displacement engine,

2921-491: A similarly converted Sunbeam Alpine . Conceived as a more weather-proof alternative to the drophead coupé TR4, the Dové provided a way for Dove Ltd. to enter the market for GT automobiles. The company substituted an accented vowel at the end of the Dové name, although it is not typically pronounced. The cars came with a heater in the engine's water jackets to assist cold starts. Tinted swing-down see-through acrylic sun visors were custom fitted. Two jump seats were located behind

3048-400: A working unit in February 1964. It originally was designated as the "Porsche 901" (901 being its internal project number). A total of 82 cars were built which were badged as 901s. However, French automobile manufacturer Peugeot protested on the grounds that in France it had exclusive rights to car names formed by three numbers with a zero in the middle. Instead of selling the new model with

3175-452: Is an iconic sports car of the early 1960s, due to its attractive styling and claimed top speed of 241 km/h (150 mph). The E-type was produced for 14 years and was initially powered by a six-cylinder engine, followed by a V12 engine for the final generation. In 1962, the MG B introduced a new era of affordable lightweight four-cylinder roadsters. The MG B used a unibody construction and

3302-451: Is fitted with rack and pinion steering , replacing the cam and lever system used on the earlier TR models. The TR4 was originally fitted with 15x4.5" disc wheels. Optional 48-lace wire wheels could be ordered with one of three finishes: painted the same colour as the car's bodywork (rare), stove-enamelled (matte silver with chrome spinners, most common) or in matte or polished chrome finishes (originally rare, but now more common). Originally,

3429-464: Is known as the "2.4 L" engine, despite its displacement being closer to 2.3 litres. The 911E (Type 911/52 engine) and 911S (Type 911/53) used Bosch mechanical fuel injection (MFI) in all markets. For 1972 the 911T (Type 911/57) was carbureted , except in the US and some Asian markets where the 911T also came with (MFI) mechanical fuel injection (Type 911/51 engine) with power increase over European models (130 hp) to 140 hp commonly known as

3556-406: Is notable for using a three-seat layout, where the front row consists of a centrally-located driver's seat. The location of the engine and driven wheels significantly influence the handling characteristics of a car and are therefore crucial in the design of a sports car. Traditionally, most sports cars have used rear-wheel drive with the engine either located at the front ( FR layout ) or in

3683-646: The 1000 km Nürburgring , and the Targa Florio . RS stands for Rennsport in German, meaning race sport . The Carrera name was reintroduced from the 356 Carrera which had itself been named after Porsche's class victories in the Carrera Panamericana races in Mexico in the 1950s. The RS was developed to meet motorsport homologation requirements. Compared to a standard 911S, the Carrera 2.7 RS had

3810-609: The 24 Hours of Daytona . The 911-derived 935 turbo also won the 24 Hours of Le Mans in 1979. Porsche won the World Championship for Makes in 1976, 1977, 1978, and 1979 with 911-derived models. In a 1999 poll to determine the Car of the Century , the 911 was fifth. It is one of two in the top five that had remained continuously in production (the original Beetle remained in production until 2003). The one millionth example

3937-520: The Audi RS 2 Avant . Ford Europe withdrew from the sports car market at the end of 1986 when the Capri was discontinued after a production run of nearly two decades. There was no direct successor, as Ford was concentrating on higher-performance versions of its hatchback and saloon models at the time. In 1989, a new generation of Lotus Elan roadster was released which used a front-wheel drive layout,

4064-541: The BMW 303 , Citroën Traction Avant and Fiat 508 — offered similar handling and comfort to the more expensive sports cars. Powerful, reliable, and economical (although softly suspended) American saloons began to be imported to Europe in significant numbers. Sports car ownership was increased through models such as the Austin 7 and Wolseley Hornet six , however many of these sports cars did not offer any performance upgrades over

4191-623: The Bentley Speed Six (1928-1930), with the former famously described by Bugatti's founder as "the fastest lorry in the world". Between the Great Depression and the World War II the pre-war era was a period of decline in importance for sports car manufacturers, although the period was not devoid of advances, for example streamlining . Cheap, light-weight family sedans with independent front suspension— such as

4318-593: The Geneva International Motor Show in March 1957. Triumph deemed the car too expensive to put into production, but did give the job of designing the new Triumph Herald to Michelotti. Later in 1957 Standard-Triumph commissioned Michelotti to develop a serious proposal for a revised TR. A prototype, code-named Zest and built on a TR3A chassis, was complete by 1958. The Zest received a full-width body style, with headlamps that were inset from

4445-520: The Jensen FF became the first sports car to use all-wheel drive . The Ford Capri is a 2+2 coupe that was produced from 1968 to 1986 and intended to be a smaller European equivalent of the Ford Mustang. A main rival to the Capri was Opel Manta , which was produced from 1970 to 1988. The 1973-1978 Lancia Stratos was a mid-engined two-seat coupe that was powered by a Ferrari V6 engine. This

4572-405: The Porsche 914 for 1973 through 1975 model years. 2,099 units were produced. The 912E was replaced by the front-engine Porsche 924 for the 1977 model year. For the 1976 model year, Porsche introduced the Carrera 3.0 with wide rear flares, optional whaletail, and a variety of other luxury options. It was available in all markets except North America. The Carrera 3.0 was fitted with a variation of

4699-403: The 1905 Isotta Fraschini Tipo D, the 1906 Rolls-Royce Silver Ghost , the 1908 Delage , the 1910 Bugatti Type 13 , and the 1912 DFP 12/15 . Early motor racing events included the 1903 Paris–Madrid race , the 1905-1907 Herkomer Trophy, the 1908-1911 Prince Henry Tour and the 1911–present Monte Carlo Rally . The Prince Henry Tours (which were similar to modern car rallies) were among

4826-426: The 1920s. The term initially described two-seat roadsters (cars without a fixed roof), however, since the 1970s the term has also been used for cars with a fixed roof (which were previously considered grand tourers ). Attributing the definition of 'sports car' to any particular model can be controversial or the subject of debate among enthusiasts. Authors and experts have often contributed their ideas to capture

4953-495: The 1921 Coppa Florio . Another approach— such as that used by Morris Garages— was to convert touring cars into sports cars. The first 24 Hours of Le Mans race for sports cars was held in 1923, although the two-seat sports cars only competed in the smallest class, with the majority of cars entered being four-seat fast touring cars. "This race, together with the Tourist Trophy Series of Races , organised after

5080-404: The 1948 Ferrari 166 S . A new concept altogether was the modern Gran Turismo class from Italy, which was in effect unknown before the war: sustained high-speed motoring from relatively modest engine size and compact closed or berlinetta coachwork. The 1947 Maserati A6 1500 two-seat berlinetta was the first production model from Maserati. In Germany, the motor industry was devastated by

5207-612: The 1965 SCCA D modified championship against Ferraris and other prepared race car exotica. In 1964 the factory-sponsored Team Triumph entered three TR4s in the Canadian Shell 4000 rally . These "works" cars were reportedly built with gussets on the chassis members and aluminium body panels to strengthen and lighten the car. After import, the engines were prepared by Kastner in New York, where they were also fitted with lightweight magnesium wheels. Although they did not place well in

5334-535: The 1973 Carrera RS. The Carrera 2.7 model produced for the North American markets, often referred to as the Carrera 2.7 CIS, was powered by the same 2.7-litre engine as the 911S which produced 175 PS (129 kW; 173 hp). The initial Carrera 2.7 models had the same welded-on rear RS flares, before switching to the SC stamped style rear flares during the middle of the 1974 production year. The Carrera 2.7 coupés weighed in at 1,075 kg (2,370 lb),

5461-499: The 1980 Deutsche Rennsport Meisterschaft and Giro d'Italia automobilistico marathon. The Montecarlo was a basis for the silhouette racing car , Lancia Rally 037 . In the 1970s, turbocharging began to be adopted by sports cars, such as the BMW 2002 Turbo in 1973, the first Porsche 911 Turbo in 1975, and the Saab 99 Turbo in 1978. Turbocharging became increasingly popular in the 1980s, from relatively affordable coupes such as

5588-452: The 1980–1986 Renault Fuego and 1992–1996 Rover 220 Coupé Turbo , to expensive supercars such as the 1984-1987 Ferrari 288 GTO and 1987-1992 Ferrari F40 . In the late 1980s and early 1990s, several manufacturers developed supercars that competed for production car top speed records . These cars included the 1986–1993 Porsche 959 , 1991–1995 Bugatti EB 110 , 1992–1994 Jaguar XJ220 and 1993–998 McLaren F1 . The 1980-1995 Audi Quattro

5715-506: The 1990s, all-wheel drive has become more common in sports cars. All-wheel drive offers better acceleration and favorable handling characteristics (especially in slippery conditions), but is often heavier and more mechanically complex than traditional layouts. Examples of all-wheel drive sports cars are the Lamborghini Huracan , Bugatti Veyron , and Nissan GT-R . Rear engine layouts are not typical for sports cars, with

5842-503: The 1995-2002 MG F , the 1996–present Porsche Boxster and the 1998–present Audi TT . Porsche 911 The Porsche 911 (pronounced Nine Eleven or in German : Neunelf ) 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

5969-471: The 3.0 engine and a flat "whale tail" in place of the ducktail spoiler along with wide body panels and large tyres. In 1974, Porsche developed the Carrera RS 3.0 with mechanical fuel injection rated at 230 PS (169 kW; 227 hp). Its price was almost twice that of the 2.7 RS, but it offered racing capability. The chassis was largely similar to that of the 1973 Carrera RSR and the braking system

6096-419: The 356 ended in 1965, but there was still a market for a 4-cylinder car, particularly in the US. The 912 , introduced in the same year, served as a direct replacement, offering the de-tuned version of 356 SC's 4-cylinder, 1,582 cc (1.6 L), 90 hp (67 kW; 91 PS) boxer four Type 616/36 engine inside the 911 bodywork with Type 901 four-speed manual transmission (a 5-speed manual transmission

6223-405: The 356's four-cylinder, 1,582 cc (1.6 L) unit. The car had four seats although the rear seats were small, thus it is usually called a 2+2 rather than a four-seater (the 356 was also a 2+2). A four or five-speed "Type 901" manual transmission was available. The styling was largely penned by Ferdinand "Butzi" Porsche, son of Ferdinand "Ferry" Porsche . Butzi Porsche initially came up with

6350-540: The 906 and 910 with a power output of 220 PS (162 kW; 217 hp). In August 1967, the A series went into production with dual brake circuits and widened (5.5J-15) wheels still fitted with Pirelli Cinturato tyres, and the previously standard gasoline-burning heater became optional. The Targa (meaning "plate" in Italian ) version was introduced. The Targa had a stainless steel -clad roll bar, as automakers believed that proposed rollover safety requirements by

6477-443: The 911 remained so strong, however, that Porsche revised its strategy and decided to inject new life into the 911 editions. 911 SC sales totaled 58,914 cars. Peter W. Schutz (CEO Porsche AG 1981–1987) wrote: The decision to keep the 911 in the product line occurred one afternoon in the office of Dr. Helmuth Bott  [ de ] , the Porsche operating board member responsible for all engineering and development. I noticed

6604-411: The 911 to meet legislative requirements around the world for both impact safety and emissions. First, the engine size was increased to 2,687 cc achieving higher torque. Second, new impact bumpers conformed with low-speed protection requirements of US regulations. Thirdly, the use of K-Jetronic CIS Bosch fuel injection in two of the three models in the line up— the 911 and 911S models, retaining

6731-415: The 911/01 engine (155 PS (114 kW; 153 hp) at 6,200 rpm) compared to the 911S's Type 911/02 (180 PS (132 kW; 178 hp) at 6,500 rpm), but 911E was quicker in acceleration up to 160 km/h (99 mph). The E series for 1972–1973 model years (August 1971 to July 1972 production) consisted of the same models, but with a new, larger 2,341 cc (2.3 L) engine. This

6858-603: The 930 Turbo's 2994 cc engine (minus the turbocharger ). The engine (dubbed the 930/02) featured K-Jetronic CIS. It developed 200 PS (147 kW; 197 hp) in contrast to the older Carrera 2.7 MFI model's 210 PS (154 kW; 207 hp). The crankcase and gearbox housing were made of aluminium rather than magnesium for improved reliability. Magnesium cases were reviled for thermal expansion/contraction issues as engines grew in displacement and heat generation also increased. The new engine, which featured bigger intake and exhaust valves, produced greater torque allowing

6985-611: The Belgian Gendarmerie. The 1976 Carrera 2.7 MFI Sondermodells were the last mechanically fuel injected 911 produced by Porsche and still featured the 1973 RS engine. For the 1976 model year, the 912E was produced for the U.S. market. This was a 4-cylinder version of the 911 in the same manner as the 912 that had last been produced in 1969. It used the I-series chassis powered by the Volkswagen 2.0 engine also used in

7112-526: The British company. Michelotti responded with the Triumph TR3 Speciale, also called the "TR Dream Car". Built by Vignale on an unmodified TR3 chassis, Michelotti's TR Dream Car incorporated many styling cues from contemporary American practice, including tailfins, a full width grille, lidded headlamps in the tops of the front wings, and a two-tone paint treatment. The TR3 Speciale debuted at

7239-466: The Carrera 3.0 to achieve the same performance as the previous Carrera 2.7, 0–100 km/h (0–62 mph) in 6.1 seconds and 0–200 km/h (0–124 mph) in 27 seconds. Both versions boasted a top speed of approximately 236 km/h (147 mph). Weight increased marginally by 45 kg (99 lb) to 1,120 kg (2,470 lb). The 911 Carrera 3.0 was produced in both targa (1,125 examples produced) and coupé (2,566) versions. The Carrera 3.0

7366-468: The Mercedes Simplex 60 hp— were production fast touring cars. The 1912 Hispano-Suiza Alfonso XIII is also considered one of the earliest sports cars, as it was a "purpose built, high performance, two-seater production automobile". The model was named after King Alfonso XIII of Spain , a patron of the car's chief designer and an enthusiast for the marque. Other early sports cars include

7493-478: The TR2 and TR3 models, but with displacement increased from 1991 cc to 2138 cc by enlarging the bore from 83 to 86 mm (3.268 to 3.386 in). The cast iron block carries the crankshaft in three main bearings, and the cast iron head has two valves per cylinder driven from a camshaft in the block via pushrods and rocker arms. The 1991 cc engine was a no-cost option for cars whose owners planned to race in

7620-478: The TR4 was a common sight at hill-climb events and various club rallies and circuit racing events. In 1965, the TR4A superseded the TR4. Although appearing nearly identical to the TR4, the TR4A was equipped with a significantly revised chassis, an independent rear suspension (IRS), and a wider front and rear track, as well as numerous changes to the exterior trim and interior fitments. An estimated 25% of TR4As sold in

7747-406: The TR4 with a seven-speed close ratio gearbox. The TR4's front suspension consists of upper and lower wishbones, and telescopic dampers. Running changes to the car included a revised front suspension geometry, indicated by a smooth upper wishbone, and a revised front brake caliper and pad size. The rear suspension includes a live axle with semi-elliptical springs, and lever-arm dampers. The TR4

7874-617: The TR4 won the E production national championship, after which the SCCA reclassified the car to D production, which class Tullius won in 1963 and '64. Soon after the TR4 was introduced, Kastner and with Mike Cook from the advertising department at Triumph in New York City convinced the company to provide three new TR4s to race in the 12 Hours of Sebring in 1963. Preparation of the cars began in September 1962 in California, where Kastner

8001-490: The TR4. The next year a privateer TR4 finished dead last in the 1964 running of the Sebring 12-hour race. Kastner returned to Sebring in 1966 with four carefully prepared TR4As, three of which finished winning the class. At Sebring in 1966, Tullius threw a piston in the most highly tuned car and did not finish. Perhaps the greatest racing victory for the TR4A was at Daytona, where a Kastner-prepared car driven by Charlie Gates won

8128-654: The US National Highway Traffic Safety Administration (NHTSA) would make it difficult for fully open convertibles to meet regulations for sale in the US, an important market for the 911. The name "Targa" came from the Targa Florio sports car road race in Sicily , Italy in which Porsche had several victories until 1973. The last win in the subsequently discontinued event was scored with a 911 Carrera RS against prototypes entered by Ferrari and Alfa Romeo . The road-going Targa

8255-545: The US were not equipped with IRS but instead reverted to a live axle system similar to the TR4's on a slightly modified TR4A chassis. A total of 43 Dové GTR4 and GTR4A fixed head coupés were produced at the direction of L. F. Dove Ltd., an auto dealership in Wimbledon, London. The conversions from standard TR4s were done by coachbuilder Harrington Motor Bodyworks , best known for building the Harrington Alpine,

8382-799: The body and chassis of the TR3A, but the 2138 cc engine and fully synchronised gearbox from the TR4. A small number of TR4s were put to use as "Fast Pursuit Cars" by police departments in places such as Manchester City and the Southend-on-Sea Borough. Only 40,253 TR4s were built during its 5-year production run, of which 37,661 cars were sold in export markets (primarily the US), and only 2,592 cars sold domestically. In comparison, 8,635 TR2s were sold during its 3-year run from 1953–1955; 74,800 TR3s in an 8-year run from 1955 to 1962; 94,500 TR6s in an 9-year run from 1968–1976, and 111,500 TR7s over

8509-479: The car appeared during the next year or two, all conforming to the same basic design and earning for themselves a reputation second to none for fast and reliable travel. The 60-h.p. cars were announced late in 1902. The cars were possessed of a very real performance superior to anything else which could be bought at the time... and the model achieved an almost invincible position among the fast cars of its day. The Sports Car: Development and Design The basis for

8636-405: The car design is optimised for dynamic performance, without any specific minimum requirements; both a Triumph Spitfire and Ferrari 488 Pista can be considered sports cars, despite vastly different levels of performance. Broader definitions of sports cars include cars "in which performance takes precedence over carrying capacity", or that emphasise the "thrill of driving" or are marketed "using

8763-419: The car was simply called the Porsche 911 Turbo worldwide. The larger engine helped reduce some of the turbo lag inherent in the earlier models. In 1989, a 5-speed manual transmission became available for the 930. The 930 was replaced in 1990 with the 964 turbo featuring the same 3.3-litre engine. There have been turbocharged variants of each subsequent generation of 911 since then. In 1978, Porsche introduced

8890-465: The car well into the 1980s until the FIA and IMSA rules were changed. For the 1978 model year, Porsche revised the 930 with a larger 3.3-litre turbocharged engine with intercooler rated at 300 PS (221 kW; 296 hp). To fit the intercooler a newly designed "tea-tray" tail spoiler replaced the earlier whale tail spoiler. Porsche dropped the "Carrera" nomenclature for the North American markets and

9017-411: The development of performance cars such as the 1910 Vauxhall Prince Henry , 1910 Sunbeam 12/16 , 1910 Talbot 25 hp , 1910 Straker-Squire 15 hp and 1913 Star 15.9 hp . Following the halt in sports car production caused by World War I , Europe returned to manufacturing automobiles from around 1920. It was around this time that the term 'Sports Car' began to appear in the motor catalogues, although

9144-455: The driver's and passenger's seats, covered in material that matched the original TR4 upholstery. A wood-rimmed wheel with riveted perimeter was fitted to some models, along with auxiliary lamps under the front bumper bars. A metallised identifying sticker with "Dové" on it was fitted to the glovebox cover. On the left rear deck below the boot cover was another identifying badge with the Dové logo. The side window glasses were specially shaped, with

9271-400: The early 1920s, the cost to produce a racing car was not significantly higher than a road car, therefore several manufacturers used the design from the current year's racing car for the next year's sports car. For example, the 1921 Ballot 2LS based on the racing car that finished third at the 1921 French Grand Prix. The Benz 28/95PS was also a successful racing car, with victories including

9398-451: The engine, a chassis was created that widened the track by four inches and extended the wheelbase by six inches over those of the TR3. In late 1958 Triumph commissioned Michelotti to create a body for the 20X development chassis. The new shape, named Zoom , was a full-width body, with tall doors having wind-down windows, and headlamps moved to the tops of the front wings. Two prototypes were complete by 1959; one convertible and one coupé with

9525-463: The exact origin of the name is not known. The decade that followed became known as the vintage era and featured rapid technical advances over the preceding Brass Era cars . Engine performance benefited from the abandonment of " tax horsepower " (where vehicles were taxed based on bore and number of cylinders, rather than actual power output) and the introduction of leaded fuel , which increased power by allowing for higher compression ratios . In

9652-531: The excitement of speed and the glamour of the (race)track" However, other people have more specific definitions, such as "must be a two-seater or a 2+2 seater" or a car with two seats only. In the United Kingdom, early recorded usage of the "sports car" was in The Times newspaper in 1919. The first known use of the term in the United States was in 1928. Sports cars started to become popular during

9779-472: The first supercars . Other significant European models of the 1960s and 1970s which might be considered supercars today are the Ferrari 250 GTO (1962-1964), Ferrari 250 GT Lusso (1963-1964), Ferrari 275 GTB/4 (1966-1968), Maserati Ghibli (1967-1973), Ferrari Daytona (1968-1973), Dino 246 (1969-1974), De Tomaso Pantera (1971-1993), Ferrari 308 GTB (1975-1980) and BMW M1 (1978-1981). In 1966,

9906-468: The first World War by the R.A.C. , appealed to the public imagination and offered to the manufacturers of the more sporting cars an excellent opportunity for boosting sales of their products." The classic Italian road races— the Targa Florio , and the Mille Miglia (first held in 1927)— also captured the public's imagination. By 1925, the higher profits available for four-seater cars resulted in

10033-431: The introduction of the whale tail rear spoiler, available as an option on the 1974-75 Carrera 2.7 models, as well as the newly introduced 930 Turbo. The Carrera 2.7 was replaced by the Carrera 3.0 for the 1976 model year, except for a special run of 113 1976 Carrera 2.7 MFI coupés were built for the German market featuring the 911/83 RS engine, with an additional 20 narrow-bodied 1976 Carrera MFI 2.7 Targas being supplied to

10160-573: The late 1920s were AC Cars , Alfa Romeo , Alvis , Amilcar , Bignan and Samson, Chenard-Walcker , Delage , Hispano-Suiza , Hotchkiss , Mercedes-Benz and Nazzaro . Two cars from the Vintage Era that would influence sports cars for many years were the Austin Seven and MG M-type "Midget". Successful sports cars from Bentley during this era were the Bentley 3 Litre (1921-1929) and

10287-417: The majority of TR4s were sold. The TR4 uses essentially the same ladder chassis with central cruciform bracing as the TR3. At 88.1 in (2,238 mm), the TR4 has the same wheelbase as the earlier car, but its track widths are 4 in (102 mm) wider in front and 2.5 in (64 mm) wider in back than the earlier model. The TR4 uses the same Standard wet liner inline-four engine that powered

10414-423: The manufacturer's team prize for Triumph. By the middle of 1960, Triumph had two potential TR replacements — Zest and Zoom — with a combined program cost of £676,000. Originally, Zest had been conceived as the TR3's replacement, while Zoom was considered for production as an upmarket model. Having seen Zoom , some at Triumph wanted it to become the next TR, but the cost to produce a detuned 20X engine killed

10541-518: The mass-produced cars upon which they were based. The highest selling sports car company of the 1930s was Morris Garages , who produced 'MG Midget' models of the M-Type , J-Type , P-Type and T-Type . The K3 version of the K-Type Magnette was a successful racing car, achieving success in the Mille Miglia , Tourist Trophy and 24 Hours of Le Mans . The Bugatti Type 57 (1934-1940)

10668-537: The middle of the vehicle ( MR layout ). Examples of FR layout sports cars include the Caterham 7 , Mazda MX-5 , and the Dodge Viper . Examples of MR layout sports cars are the Ferrari 488 , Ford GT , and Toyota MR2 . To avoid a front-heavy weight distribution , many FR layout sports cars are designed so that the engine is located further back in the engine bay, as close to the firewall as possible. Since

10795-544: The most common layout for sports cars was a roadster (a two-seat car without a fixed roof). However, there are also several examples of early sports cars with four seats. Sports cars are not usually intended to transport more than two adult occupants regularly, so most modern sports cars are generally two-seat or 2+2 layout (two smaller rear seats for children or occasional adult use). Larger cars with more spacious rear-seat accommodation are usually considered sports sedans rather than sports cars. The 1993-1998 McLaren F1

10922-421: The narrow rear arches of the old 2.4, now had a 2.7-litre engine rated at 150 PS (110 kW; 148 hp) and 175 PS (129 kW; 173 hp), respectively. The standard 911 version received an increase to 165 PS (121 kW; 163 hp) for Model Year 1976, which meant that starting from MY 1976, there was only a difference in power of 10 hp between the 911 and the 911S. The engine remained

11049-448: The new version of the 911, called the '911SC'. Porsche reintroduced the SC designation for the first time since the 356SC (as distinguished from the race engined 356 Carrera). There was no Carrera version of the 911SC. According to modern-day Porsche literature and websites (there is no period reference to SC meaning anything) the "SC" stands for "Super Carrera". It featured a 3.0-litre aluminium engine with Bosch K-Jetronic fuel injection and

11176-755: The notable exception of the Porsche 911 . The front-wheel drive layout with the engine at the front ( FF layout ) is generally the most common for cars, but it is not as common among traditional sports cars. Nonetheless, the FF layout is used by sport compacts and hot hatches such as the Mazdaspeed3 . Sports cars with an FF layout include the Fiat Barchetta , Saab Sonett , or Opel Tigra . The ancestor of all high-performance cars had its origin in Germany. The 28-h.p. Cannstatt-Daimler racing car of 1899

11303-469: The oil tank back to the original behind-the-wheel location. This change was in response to complaints that gas-station attendants often filled gasoline into the oil tank. In January 1973, US 911Ts were switched to the new K-Jetronic CIS (Continuous Fuel Injection) system from Bosch on Type 911/91 engine. 911S models also gained a small spoiler under the front bumper to improve high-speed stability. The cars weighed 1,050 kg (2,310 lb). The 911 ST

11430-456: The philosophy of achieving performance through minimizing weight and has been rated as one of the top 10 sports cars of the 1960s. The Elan featured fibreglass bodies, a backbone chassis, and overhead camshaft engines. A different style of roadster was the AC Cobra , released in 1962, which was fitted with V8 engines up to 7.0 L (427 cu in) in size by Shelby . The Porsche 911

11557-440: The previous side-curtains, making the TR4 a true convertible. The taller, more squared-off rear body line encloses a capacious boot for a sports car. The car's bonnet has a power bulge or "bubble" offset to one side to clear the engine's two carburettors. Early cars have a short bubble, while cars after CT 6429 have a longer bubble. The TR4 offered an optional hard top consisting of a fixed glass backlight with integral rollbar and

11684-423: The production of two-seat sports cars being limited to smaller manufacturers such as Aston-Martin (350 Astons built from 1921 to 1939) and Frazer-Nash (323 cars built from 1924 to 1939). Then by the late 1920s, the cost of producing racing cars (especially Grand Prix cars) escalated, causing more manufacturers to produce cars for the growing sports car market instead. Significant manufacturers of sports cars in

11811-511: The project. Ultimately management decided that neither Zest nor Zoom adequately addressed the target market, so the final design for the TR4 was based on Zest , but included some features from Zoom , including the wider track and hardtop option. The TR4's new body, produced in Triumph's Speke factory, does away with the cutaway door design and sloping boot lid of the previous TRs. The taller doors allow room for wind-down windows in place of

11938-474: The racing version called the Porsche 934 of 1976 participating at the 24 Hours of Le Mans and other races including battles with the BMW 3.0 CSL "Batmobile" . The FIA Group 5 version called Porsche 935 evolved from the 934. Fitted with a slope nose or "slant nose", the 500+ PS car was campaigned in 1976 by the factory, winning the world championship title. Private teams went on to win many races, like Le Mans in 1979, and continued to compete successfully with

12065-568: The rally, the surviving cars have become quite valuable, one of which is owned by Neil Revington, the proprietor of Revington TR in the UK. Indeed, the TR4 became a celebrated rally car in Europe and the UK during early to mid-sixties, and various replicas are still campaigned by privateers in vintage rally events throughout Europe. The TR4 continues to be raced in vintage sports car events, and even won an SCCA class championship as late as 1991. In Australia

12192-482: The same weight as the 1973 Carrera RS Touring. For the 1974 model year, the Carrera 2.7 was available with the "ducktail" rear spoiler first introduced with the 1973 Carrera RS. In the North American markets, the ducktail was standard equipment for the Carrera. All other markets the ducktail was optional, except for the home German market where the ducktail had been outlawed by the TÜV road homologation department. This led to

12319-527: The saving coming from thin gauge steel used for parts of the body shell and also the use of thinner glass. In total, 1,580 units were made, and qualified for the FIA Group 4 class. 49 Carrera RSR cars were built with 2,808 cc (2.8 L) engines rated at 300 PS (221 kW; 296 hp). For the 1974 IROC Championship (which started in December 1973), 1973 Carrera RSR models were fitted with

12446-460: The sides and set high in the grille to stand above the bonnet, which was shaped into cowls over the lamps. Around this time Triumph's Competitions department was working on a new high performance engine with the development label 20X , later named Sabrina after contemporary British actress Norma Ann Sykes , the 20X is an inline four cylinder engine with dual overhead camshafts , and was expected to develop 160 hp (119 kW). To accommodate

12573-558: The sporting events of the period, bringing renown to successful entrants. The Prince Henry Tours started the evolution of reasonably large and technically advanced production sports cars. In England, the development of sporting cars was inhibited by the Motor Car Act 1903 , which imposed a speed limit of 20 mph (32 km/h) on all public roads. This led to the 1907 opening of the Brooklands motor circuit , which inspired

12700-408: The sports car is traced to the early 20th century touring cars and roadsters , and the term 'sports car' would not be coined until after World War One. A car considered to be "a sports-car years ahead of its time" is the 1903 Mercedes Simplex 60 hp , described at the time as a fast touring car and designed by Wilhelm Maybach and Paul Daimler . The Mercedes included pioneering features such as

12827-476: The sports car, but also the most important and diverse technical developments [and] very rapid and genuine improvement in the qualities of every modern production car; assisted by new design and manufacturing techniques a consistently higher level of handling properties has been achieved." In Italy, a small but wealthy market segment allowed for the manufacture of a limited number of high-performance models directly allied to contemporary Grand Prix machines, such as

12954-402: The tyres most commonly fitted were 590-15 bias ply or optional radial tyres. At one point, American Racing alloy (magnesium and aluminium) wheels were offered in the US as an option, in 15x5.5" or 15x6" size. The first production TR4 was built on 18 July 1961, and received commission number CT1. The last car was built on 6 January 1965, with commission number CT40304. Final assembly of the cars

13081-496: The under-two-litre classes of the day. At different times the factory installed either a pair of SU H6 carburettors, or a pair of Zenith-Stromberg CD175s. The car's four speed plus reverse manual transmission has synchromesh on all forward gears, an upgrade from the transmission in the TR3 which did not synchronize first gear. Additionally, the optional Laycock de Normanville electrically operated overdrive could be selected for second, third, and fourth gears, effectively providing

13208-438: The unusual oil filler behind the right side door, with the dry sump oil tank relocated from behind the right rear wheel to the front of it in an attempt to move the centre of gravity slightly forward for better handling. An extra oil filler/inspection flap was located on the rear wing, for this reason it became known as an "Oil Klapper", "Ölklappe" or "Vierte Tür (4th door)". The F series (August 1972 to July 1973 production) moved

13335-407: The vinyl insert and frame could be. The factory offered the rigid top and backlight assembly as the "Hard Top kit", and the vinyl insert and frame separately as the "Surrey top". The revised interior introduced adjustable fascia ventilation and a collapsible steering column. Features such as these were seen as necessary to keep pace with the competition, particularly in the important US market where

13462-423: The war, but a small number of manufacturers returned it to prominence. In 1948, the Porsche 356 was released as the debut model from Porsche. The significance of the Porsche 356 and its successors was described in 1957 as "future historians must see them as among the most important of mid-century production cars". The 1954 Mercedes-Benz 300 SL is another significant car from this era. The 1961 Jaguar E-Type

13589-401: The wide 205/50R15 & 225/50R15 Pirelli P7 tyres, and a large rear spoiler often known as a " whale tail " on the early cars (modified from the original 1974 IROC design). They were initially fitted with a 3.0-litre engine producing 260 PS (191 kW; 256 hp), and a four-speed manual transmission. Production of the first 400 units qualified the 930 for FIA Group 4 competition. With

13716-400: The years but the basic concept has remained unchanged. The engines were air-cooled until the introduction of the 996 series in 1998. The 911 has been raced extensively by private and factory teams, in a variety of classes. It is among the most successful competition cars. In the mid-1970s, the naturally aspirated 911 Carrera RSR won world championship races including Targa Florio and

13843-415: Was a pioneering all-wheel drive sports car. The 1995 Porsche 911 Turbo (993) saw the 911 Turbo model switch to all-wheel drive, a drivetrain layout that the model uses to this day. The BMW M3 was released in 1986 and has been produced for every generation since. The 1993-1996 Mercedes-Benz W124 E36 AMG was the mass-produced AMG model. Audi's equivalent division, called "RS", was launched in 1994 with

13970-684: Was an unusual arrangement for a car used to compete in rallying, nonetheless it was very successful and won the World Rally Championship in 1974 , 1975 , and 1976 . The Lancia Montecarlo was produced from 1975 to 1981 and is a mid-engine two-seater, available as a coupé or a targa-top. It was sold as Lancia Scorpion in the USA. Its racing variant, Montecarlo Turbo, won the 1979 World Championship for Makes in its division and overall for 1980 World Championship for Makes and 1981 World Endurance Championship for Makes . Montecarlo also won

14097-627: Was another significant sports car of the pre-war era and is now among the most valuable cars in the world. The T57 was successful in sports car races, including winning the 1937 24 Hours of Le Mans and 1939 24 Hours of Le Mans . Another successful Bugatti sports car was the Bugatti Type 55 (1932-1935), which was based on the Type 51 Grand Prix racing car. The decade following the Second World War saw an "immense growth of interest in

14224-608: Was available with a manual gearbox (type 915) with 4 or 5 speeds as well as 3-speed automatic transmission (called the Sportomatic). Production totals were 3,691 manual cars and 58 Sportomatic cars. For the 1975 model year, Porsche introduced the first production turbocharged 911. Although called the 930 Turbo (930 being its internal type number) in Europe, it was marketed as the 930 Turbo Carrera in North America. The body shape incorporated wide wheel-arches to accommodate

14351-527: Was canceled after the 1980 model year partly because of the elimination of a forward gear to make it a three-speed. The B series went into production in August 1968, replacing the 911L model with 911E with fuel injection. It remained in production until July 1969. The 911E gained wider tires on 6J-15 wheels. The C series was introduced in August 1969 with an enlarged 2.2-litre engine (84 mm bore x 66 mm stroke). The wheelbase for all 911 and 912 models

14478-433: Was developed as a more powerful, larger and a more comfortable replacement for the 356 , the company's first model. The new car made its public debut at the 1963 Frankfurt Motor Show ( German : Internationale Automobil-Ausstellung ). The car was developed with the proof-of-concept twin-fan Type 745 flat-six engine, but the car presented at the auto show had a non-operational mockup of the single-fan 901 engine, receiving

14605-494: Was done at Triumph's Canley-Fletchamstead factory near Coventry. TR4s were also assembled from Complete Knock-Down (CKD) kits in Mechelen, Belgium and Borgo Panigale, Italy, the latter in a factory owned by Ducati . American Triumph dealers were concerned that buyers might not accept the car's updated styling, so a brief special run of TR3s, commonly called TR3Bs , was produced for the US market in 1961 and '62. These cars have

14732-446: Was dropped in the production version. The first 911 Cabriolet debuted in late 1982, as a 1983 model. This was Porsche's first cabriolet since the 356 of the mid-1960s. A total of 4,214 were sold in its introductory year, despite its premium price relative to the open-top targa. Cabriolet versions of the 911 have been offered ever since. In 1979, Porsche had made plans to replace the 911 with their new 928 company flagship . Sales of

14859-444: Was equipped with a removable roof panel and a removable plastic rear window (although a fixed glass version was offered from 1968). The 110 PS (81 kW; 110 hp) 911T was also launched in 1967 with Type 901/03 engine. The 130 PS (96 kW; 128 hp) model was renamed the 911L with Type 901/06 engine and ventilated front disc brakes. The brakes had been introduced on the previous 911S. The 911R with 901/22 engine had

14986-453: Was from the 917 racing car. The use of thinner metal plate panels and a minimalist interior enabled its weight to be reduced to around 900 kg (2,000 lb). The Carrera RSR 3.0 was sold to racing teams and scored wins in several major sports car races of the mid-1970s. Also, a prototype Carrera RSR Turbo (with 2.1-litre engine due to a 1.4x equivalency formula) came second at the 24 Hours of Le Mans in 1974 and won several major races,

15113-439: Was increased from 2,211–2,268 mm (87.0–89.3 in), to help as a remedy to the car's nervous handling at the limit. The overall length of the car did not change, but the rear wheels were relocated further back. Fuel injection arrived for the 911S (901/10 engine) and for a new middle model, 911E (901/09 engine). The D series was produced from Aug. 1970 to July 1971. The 2.2-litre 911E (C and D series) had lower power output of

15240-621: Was manufactured in May 2017 and is in the company's permanent collection. Although Porsche has used internal code numbers for each series of the 911, all models have been marketed and sold as 911s. The model series and associated internal codes are as follows: A series letter is used by Porsche to indicate the revision for production cars, usually on an annual basis. 911s have also been categorized into families based on body styles or engine enhancements: The 911 traces its roots to sketches drawn by Ferdinand "Butzi" Porsche in 1959. The Porsche 911

15367-537: Was optional). In 1966, Porsche introduced the more powerful 911S with Type 901/02 engine having a power output of 160 PS (118 kW; 158 hp). Forged aluminium alloy wheels from Fuchsfelge , with a 5-spoke design, were offered for the first time. In motorsport at the same time, the engine was developed into the Type 901/20 and was installed in the mid-engine 904 and 906 with an increased power output of 210 PS (154 kW; 207 hp), as well as fuel injected Type 901/21 installed in later variants of

15494-412: Was partly relieved by the sale of Triumph's tractor division to Massey-Harris of Canada. A long overdue refresh of their small sedans was further complicated by the departure of chief stylist Walter Belgrove over a disagreement with the direction of the redesign. After being introduced to Giovanni Michelotti , Triumph managing director Alick Dick invited the Italian designer to produce a concept car for

15621-573: Was produced in small numbers for racing (the production run for the ST lasted from 1970 to 1971).
