121-555: The Holden Torana is a mid-sized car that was manufactured by Holden from 1967 to 1980. The name apparently comes from a word meaning "to fly" in an unconfirmed Aboriginal Australian language. The original HB series Torana was released in 1967 and was a four-cylinder compact vehicle closely based on the British Vauxhall Viva HB series of 1966–1970. Whilst the 1969–1973 (LC and LJ series) cars included more popular, longer-wheelbase six-cylinder versions, and with

7865-425: The first ultra-performance Torana, the GTR XU-1, was developed by Holden along with Harry Firth of the Holden Dealer Team for competition in popular Series Production touring car racing within Australia, as well as in off-road rallying and unique rallycross events. However, the highlight purpose of the Torana GTR XU-1 was to keep the Holden brand competitive against the larger and more powerful Ford Falcon GT-HO in
7986-481: The fours and sixes were also available for export markets. Exports to the Philippines also occurred, where it was sold as the "Holden 1900". The 5.0-litre engine was reserved for the sporting LH Torana SL/R 5000 sedan. A special build derivative of the SL/R 5000 was the Bathurst-intended 'L34 Option', of which only 263 were built, with a higher-compression engine with stouter components for more power and durability in competition use. The most notable external feature of
8107-415: The grille (with vertical bars) and distinctive chrome wheel covers. It was marketed as a four-door sedan and as a three-door hatchback, unlike the short-lived four-cylinder LX Torana. The introduction of Sunbird also coincided with the first attempt by Holden to add a handling package to its range of cars. The introduction of 'radial-tuned suspension' (RTS) began with the LX Sunbird sedan and hatchback and then
8228-458: The larger Holden HQ series. Many mechanical components were carried over from the LC-series, with some changes to the choice of engines. The four-cylinder Torana retained its Vauxhall designed 1200OHV and 1600OHC engines, but was now also available with a 1300cc OHV unit. The base two-door car was now simply called the Torana 1200, while the 1300 engine equipped the Torana Deluxe model in either two-door or four-door form. The optional 1600 OHC engine
8349-440: The late 1970s, when rising fuel costs and government fuel economy regulations caused all car classes to shrink, and in many cases to blur. Automakers moved previously "full-size" nameplates to smaller platforms such as the Ford LTD II and the Plymouth Fury . A comparison test by Popular Science of four intermediate sedans (the 1976 AMC Matador, Chevrolet Malibu , Ford Torino, and Dodge Coronet ) predicted that these will be
8470-489: The leading edges of the front fenders and to the rear boot lid. In early 1968, a "Series 70" engine option—equivalent to the '90' option for the British Vauxhall Viva—was added. This engine had a higher compression ratio and higher-lift camshaft (adapted from the Brabham option engine) and a single CD Zenith-Stromberg carburettor, which boosted output to 69 bhp (51 kW; 70 PS). Power-assisted front disc brakes were standardised with this engine, whilst availability of
8591-412: The locally produced 1,892-cc Starfire Four engine that was also installed into the Australian-produced versions of the Toyota Corona and in four-cylinder versions of the Holden Commodore. This sluggish motor was simply a crudely cut-down version of the long-running Holden six-cylinder engine. The hatchbacks were deleted in 1979, leaving only the sedans for the 1980 model year. The last Australian Sunbird
8712-552: The mid-20th century, the straight-six layout was the most common design for engines with six cylinders. However, V6 engines became more common in the 1970s. By the 2000s, V6 engines replaced most straight-six engines. In terms of packaging, straight-six engines are almost always narrower than a V6 engine or V8 engine , but longer than straight-four engines , V6s, and most V8s. Straight-six engines are typically produced in displacements ranging from 2 to 4 L (122 to 244 cu in), however engines ranging in size from
8833-881: The mid-size market in the 1980s and 1990s included the Chrysler K-Cars ( Dodge Aries and Plymouth Reliant ), the Ford Taurus , and the Toyota Camry , which was upsized into the midsize class in 1991. The Taurus and Camry came to define the mid-size market for decades. Mid-size cars were the most popular category of cars sold in the United States, with 27.4 percent during the first half of 2012, ahead of crossovers at 19 percent. The United States Environmental Protection Agency (EPA) Fuel Economy Regulations for 1977 and Later Model Year (dated July 1996) includes definitions for classes of automobiles. Based on
8954-454: The most obvious changes were to replace the LH's rectangular headlights with round headlights, side window surrounds were changed from body colour to black, and the front Holden badge was enlarged. A two-door hatchback body was introduced as an alternative to the four-door sedan, although the 1,897-cc Opel unit was not offered in the new body style. Soon after its introduction, in July 1976 the LX
9075-476: The new emissions rules, power from the Opel-sourced engine was down from 76 to 72 kW (102 to 96 hp). From this point, all four-cylinder models were marketed as Sunbirds and the six- or eight-cylinder models as Toranas. The original LX series Sunbird was a single-trim range, with four-speed manual and three-speed automatic transmissions. There were minor trim differences compared to the Torana, notably
9196-430: The nimble XU-1 the power boost it needed to seriously challenge the powerful Ford Falcon GTHO Phase III , which had won the 1971 Hardie-Ferodo 500 production-car endurance race held annually at Bathurst . In the somewhat wet 1972 Hardie-Ferodo 500 , the lightweight HDT Torana GTR XU-1 was able to finally claim victory against the heavyweight GT-HO, driven solo for 500 miles (800 km) by Peter Brock . This would be
9317-480: The performance level significantly with its uniquely specified '2600S' six-cylinder engine. As for general features, a three-person front bench seat became available as an option for four-door S and SL six-cylinder models. Later in production (July 1971), the 161-ci engine was replaced with a larger 173-ci version (badged as the '2850') which also made it into the last of the LC GTR cars as the '2850S'. In August 1970,
9438-476: The recessed door handles now required by Australian Design Rules [ADRs]; further to this, all LC four-cylinder cars carried over HB body panels forward of the 'A' pillar. The LC-series was available in two-door and four-door versions of base (four-cylinder only), S, or SL specification, as well as a two-door sports model called the GTR. The new Torana GTR effectively replaced the previous series' Brabham Torana, but raised
9559-582: The same V8 engine he had developed for the stillborn V8 GTR XU-1 would have solved this problem, as the HDT had already cured the oil problems, but Holden ignored his warnings. Prototype wagon and hatchback versions of the LH Torana were built, but never reached production. Overall, a total of 70,184 LH Toranas were built. A few special models of the LH were built, the somewhat sporting Plus 4 and G-Pak models. The Plus 4 arrived in September 1974 and
9680-516: The similar 130OHV and 1760OHV four-cylinder Vauxhall Viva HC range was also sold there. The 2850S model, with bucket seats and four-speed floor shift or console shift Trimatic three-speed automatic, was also shipped to New Zealand in CKD kit form for local assembly from 1973, becoming the first Kiwi-built Torana. In South Korea the LJ Torana was built and sold by GM Korea as the Chevrolet 1700 , with
9801-560: The standard 56 bhp (42 kW; 57 PS) engine. The Brabham Torana became an independent model in its own right—(option XS5) based upon the Torana S two-door sedan—complete with bold specific 'Brabham Torana' badging front and rear and on the flanks, and new black accent body decoration. Its interior specification included a sports steering wheel (from the contemporary Holden HK Monaro GTS) and uniquely comprehensive dash instrumentation with tachometer and three supplementary gauges. The HB Torana continued until late 1969. Total production
9922-590: The start of the 'Peter Perfect'/Torana legend, and the first of five Bathurst wins for the Torana in its colourful 10-year racing career at Bathurst. The Holden Dealer Team also developed a 300 bhp (224 kW; 304 PS), 308ci V8-powered version of the GTR XU-1, often erroneously referred to as the GTR XU-2. The V8 Torana did race in Sports Sedan racing in the hands of Brock and Colin Bond , and
10043-674: The time was the reigning F1 World Champion and Australian of the Year for 1966. The Brabham Torana's engine featured twin CD Zenith-Stromberg carburettors fitted with individual sports air cleaners. Together with a low-restriction exhaust system, power was boosted to 79 bhp (59 kW; 80 PS). The Brabham option (available only with manual transmission on Torana S or Torana SL) also included wider wheel rims and red-wall tyres, power-assisted front disc brakes, black body accents, and subtle 'Brabham' identification badges attached to
10164-523: Was 16,318 with imported panels and 20,243 with the locally manufactured bodies. The next generation of Holden Torana, the LC-series, appeared in October 1969 and was made available with a range of a four-cylinder or six-cylinder engines. The inline six had a capacity of 138 cu in (badged as the '2250'); a 161 cu in engine (badged as the '2600') was optional. The six-cylinder cars had
10285-521: Was added; this engine was also sourced from Vauxhall in the UK. The 1600 OHC engine option also included a strengthened gearbox. Body styles were based upon the previous HB-series, but the new six-cylinder cars were of a significantly different external appearance. All LC Toranas shared a new body shape rear of the 'B' pillar, but shared windscreen and front doors carried over from the HB-series (modified with
10406-408: Was an attempt to move a few more of the slow-selling four-cylinder models. The G-Pak, first seen in February 1975, received the 3.3-litre inline-six. Both came with a four-speed manual, sporting instrumentation, and disc brakes in front. New Zealand assembly got off to a troubled start. General Motors New Zealand , which still had a wide four-cylinder Vauxhall Viva / Magnum line on sale, had planned
10527-439: Was available for some column shift models. The LC Torana scored Wheels magazine's Car of the Year award for 1969. The four-cylinder engine was initially of 1,159 cc, and offered either 56 or 69 hp (42 or 51 kW). The more powerful Brabham Torana engine was not carried over to the LC-series and the model itself was also discontinued. In July 1971, a bigger overhead cam 1.6-litre engine with 80 hp (60 kW)
10648-658: Was built in September 1980. The Sunbird was replaced initially by a four-cylinder version of the Holden Commodore , before the arrival of its natural, albeit smaller, successor, the Holden Camira , from 1982. At one point, design consideration was given to a five-door hatchback version of the UC Torana, which had a similar side profile to the Rover SD1 and rode an extended wheelbase. The idea never got past
10769-480: Was called a compact to distinguish it from the small imported cars that were being introduced into the marketplace. By the early 1960s, the car was renamed the Rambler Classic and while it retained its basic dimensions, it was now competing with an array of new "intermediate" models from General Motors, Ford, and Chrysler. The introduction of the 1962 Ford Fairlane was viewed by consumers as too close to
10890-605: Was called the UC SL/T. These were mainly ordered through Suttons in NSW, but one is known to have been ordered through Zupps in Queensland. These were produced in a mini production run of five cars and only 33 were built. Only one is known to exist today that was ordered through Zupps. The Holden Sunbird was also updated to UC specifications and continued to sell well as a 1.9-litre four-cylinder car, sharing its body architecture with
11011-707: Was developed by Repco for the LH SL/R 5000 H.O. L34. The A9X version of the Torana had a larger 10-bolt Salisbury differential with disc brakes and had the option of the Borg Warner Super T10 four-speed. Hardly any cars were delivered with Super T10 option, so in effect the immortalized A9X was a pretty stock car with a better differential and suspension. The LH Torana in L34 form won the Bathurst 1000 touring car race with Peter Brock and Brian Sampson in 1975 and with Bob Morris and John Fitzpatrick in 1976, with
11132-582: Was developed in Australia, with four-door bodies shipped back to the UK to be constructed and sold as the Viva saloon. However, the Vauxpedia website, after extensive research with Vauxhall, maintains that the four-door was designed in England, to compete with Ford's four-door Escort, and both Holden and Vauxhall made their own body panels for their respective Torana and Viva versions. A collapsible steering column
11253-416: Was expected to fetch over $ 1,000,000 at auction. The introduction of the UC Torana in March 1978 occasioned the demise of V8 power and the cessation of the sporting SL/R variant in the Torana range of cars. The UC series featured a significantly modernised frontal appearance and a completely new interior dash layout. Torana was now rationalised to a choice of two equipment levels and two six-cylinder engines,
11374-477: Was extensively road tested by HDT boss Harry Firth and young team engineer/driver Larry Perkins , but the car never made it past the prototype stage. This was due to the ' supercar scare ' of 1972, which involved vast political pressure being placed upon Holden, Ford, and Chrysler to abandon their proposed specially built 'Bathurst Supercars', such as the V8 GTR XU-1. This was the result of a media frenzy that
11495-469: Was followed by an IOE version in 1916. The 1951 Hudson Hornet introduced a 308 cu in (5.0 L) flathead straight-six engine. These engines dominated dirt track and NASCAR racing at the time. Production of the Hudson I6 continued after the 1954 merger forming American Motors Corporation and was eventually replaced by a new Rambler V8 after 1956. In 1924, Chrysler began production of
11616-589: Was followed by the AJ6 and AJ16 engines, produced from 1984 to 1996, before being replaced by a Ford-derived V6 engine. The 1948–1959 Lagonda straight-6 dual overhead camshaft petrol engine was used in various Aston Martin and Lagonda cars. This engine's successor was the Tadek Marek-designed straight-six used in the DB4 (1958), DB5 (1963), DB6 (1965) and DBS (1967). The Ford Zephyr 6 overhead valve engine
11737-412: Was followed by the 1962–1988 Chevrolet Turbo-Thrift engine (also using an overhead valve design), which was replaced by various General Motors V6 engines. The 1952 through 2006 AMC Straight-6 petrol engine initially used a flathead design before being upgraded to an overhead valve design in 1956. A new I6 design with a short stroke and seven main bearing crankshaft was introduced in 1964. The engine
11858-423: Was followed by the first generation Toyota F overhead valve engine, which was produced from 1949 to 1975, which in turn was followed by the 2F version from 1975 to 1988 and the fuel-injected 3F / 3FE version from 1988 to 1992. This was replaced by the dual overhead camshaft Toyota FZ engine , produced from 1993 until 2008. Produced alongside these engines was the single overhead camshaft Toyota M engine , which
11979-531: Was introduced in 1929 as a replacement for the brand's straight-four engines and was produced in displacements of 181 cu in (3.0 L), 194 cu in (3.2 L) and 207 cu in (3.4 L). The second generation of this engine family - often referred to as the Blue Flame engine - was produced from 1937 to 1962 in displacements of 216 cu in (3.5 L), 235 cu in (3.9 L) and 261 cu in (4.3 L). This
12100-407: Was introduced in 1965 and produced over seven generations until 1993 (with the 7M-GTE being the final version of the M engine). The M engine was replaced by the dual overhead camshaft Toyota JZ engine , which was produced from 1990 to 2007 and is arguably known as Toyota's best straight-six engine. Toyota's third line of straight-six engines was the 2.0 L Toyota G engine , which was released as
12221-670: Was introduced in the Willys Jeep Station Wagon . At the time of its introduction, the Tornado engine had the lowest specific fuel consumption of an American gasoline (petrol) engine. The Tornado engine was replaced by the AMC I6 engine. In 2001, General Motors resumed production of straight-six engines with the Vortec 4200 dual overhead camshaft petrol engine. This engine was used in various SUV models until 2009. Also,
12342-647: Was introduced in the Dutch Spyker 60 HP racing car in 1903. Straight-six engines increased in popularity in the years after and by 1909, approximately 80 manufacturers were using them (including 62 in the United Kingdom). Prior to the 1950s, V6 engines were rarely used, due to the poorer engine balance of V6 engines compared to straight-six engines. Since the 1980s, however, the shorter length of V6 engines has seen most manufacturers replace straight-six engines with V6 engines. An exception to this trend
12463-653: Was later in the year to be increased in capacity, badged as the 1760 OHC. Otherwise, the 2250 and 2850 engines carried over into the revised six-cylinder Torana models, and the 3300 engine (known as the 202 in the HQ range) was adopted as the engine for the LJ Torana GTR sedan. Gearbox choices remained the same across the range. A race-bred version of the 3300 engine was also fitted to the LJ Torana GTR XU-1, producing 190 bhp (142 kW; 193 PS). By now
12584-549: Was now fitted, together with a new recessed instrument cluster, new indicator switch, and new steering wheel borrowed from the contemporary full-sized Holden HK-series. These local components replaced the previously imported Vauxhall items. A consequence of using these local components was the loss of the stalk-operated headlight dip switch and horn. The dip switch ended up on the floor, as was the case for full-sized Holdens. Dual-circuit brakes were now standard on all models, though power-assisted front disc brakes were still optional with
12705-451: Was optional. Drum brakes were fitted front and rear, with power-assisted front disc brakes optional. In terms of styling, the only points of visual difference between Viva and Torana were in the grille and headlamps, the rear tail panel (no registration plate recess), the deletion of the Viva's dashboard air vents, the wheel trims, and the badging—otherwise it was very much a straightforward exercise in badge engineering. Holden's HB Torana sedan
12826-527: Was powered by a 1.3-1.6 L overhead camshaft straight-six petrol engine. The 1931–1932 MG F-type tourers, 1932–1934 MG K-type sports cars, and 1934–1936 MG N-type sports cars were powered by an overhead camshaft straight-six petrol engine. During the mid-1930s, the Riley MPH sports car and Riley Kestrel 6 saloon were produced in small numbers and were powered by dual overhead camshaft straight-six petrol engine. The 1947 Bristol 400 luxury car
12947-613: Was powered by an overhead valve straight-six petrol engine based on the design of the BMW M328 engine. This engine remained in use until the Bristol 406 was discontinued in 1961. The dual overhead camshaft Jaguar XK6 engine petrol engine was produced from 1948 to 1992 in the Jaguar XK120 sports car. Introduced as a 3.4 L, it was used in passenger and racing cars, produced in displacements of 2.4 to 4.2 L. The XK6 engine
13068-516: Was powered by the Daewoo XK6 straight-six petrol engine, which is one of the few straight-six engines to be used in a transverse engine front-wheel drive car. From the 1950s to the 2010s, many cars produced in Australia were powered by a straight-six engine. Holden's first car, the 1948 Holden 48-215 sedan, was powered by the Holden 'grey' motor , an overhead valve petrol engine. This engine
13189-543: Was released in February 1974 on the Australian market only, in both two- and four-door forms, as the TA Torana. It was only produced for 11 months with a total production run of 11,304 units. March 1974 had the first completely new Torana body, with the arrival of the larger mid-sized LH series, produced in four-door sedan style only. Despite the larger external size, the car was relatively cramped by mid-1970s standards. It resembled other GM products of its generation, notably
13310-419: Was replaced by Chevrolet's straight-six engine and Buick's V6 engine. a The overhead valve Buick Straight-6 petrol engine was introduced in the 1914 Buick Six luxury car and was produced until 1930. Buick did not make another six-cylinder engine until they introduced a V6 engine in 1962. The 1916 through 1926 Hudson Super Six was powered by a 289 cu in (4.7 L) straight-six petrol engine. This
13431-605: Was replaced by the Austin D-Series engine , an overhead valve engine initially designed for trucks, which was used in passenger cars from 1947 until 1968 (along with several Jensen Motors models from 1946 to 1962). The overhead valve BMC C-Series was used by various BMC brands from 1954 to 1971, followed by the 2.2 L version of the BMC E-Series overhead camshaft engine, which was produced from 1970 until 1982. The 1930–1936 Wolseley Hornet six lightweight car
13552-532: Was replaced by the Holden 'red' motor , which was produced from 1963 to 1980 and in turn followed by the 1980–1984 Holden 'blue' motor . The final locally produced Holden straight-six was the 1984–1986 Holden 'black' motor , which was initially replaced by the Japanese-built Nissan RB30 engine before Holden switched to a locally-built V6 engine. Ford produced straight-six engines for the longest time of any Australian manufacturer. In 1960,
13673-479: Was replaced by the 1906–1926 Rolls-Royce Silver Ghost , which switched to a flathead (side-valve) design for its straight-six engine. In 1906, the Standard Six luxury car was introduced, powered by a 20 hp (15 kW; 20 PS) I6 petrol engine. Standard's engines were also used in several cars built by SS Cars and its successor Jaguar, such as the 1932 SS 1 sports car, the 1936 SS Jaguar 100 and
13794-451: Was reporting against these soon-to-be released "bullets on wheels" available to the general public. In effect, all three manufacturers (Holden, Ford and Chrysler ) bowed to this pressure, and Holden postponed its introduction of a V8 Torana for two years until the release of the larger LH series Torana in 1974. A total of 81,813 LJ Toranas were built by Holden in Australia, with some exported to New Zealand, but only in six-cylinder form, as
13915-405: Was retailed in three model specifications: Torana, Torana S, and Torana SL ... these models effectively mirrored the concurrent larger HR Holden sedans with their three-tiered specification of Standard, Special, and Premier. A 'sports' option package was released in October 1967, called the 'Brabham' Torana, named in honour of the well-respected Australian race-car driver, Sir Jack Brabham , who at
14036-467: Was rugged, reliable, and became noted for longevity. A turbocharged racing engine based on the AMC Straight-6 engine block produced 875 hp (652 kW) and competed in the 1978 Indianapolis 500 race. The final application for the AMC Straight-6 engine was the 2006 Jeep Wrangler (TJ) , after which a V6 replaced it. The 1962 through 1973 Jeep Tornado overhead camshaft straight-six engine
14157-497: Was subjected to performance-reducing engine modifications to comply with new ADR27A emission regulations. Power outputs (from now on specified in kilowatts , as part of Australia's metrication programme ) changed as: When the LX Torana was introduced, it featured a choice of four-, six-, and eight-cylinder engines. In November 1976 the four-cylinder Torana was revised and relaunched as the Holden LX Sunbird. Reflecting
14278-486: Was subsequently discontinued in 1979, followed by the four-cylinder Sunbird in 1980. Introduced in May 1967 to replace the HA series Vauxhall Viva in the Australian market, the first Torana model was a mildly facelifted HB series Vauxhall Viva. It featured a two-door body, 12-inch (305-mm) wheels, and a 56-bhp 1.2-litre four-cylinder engine mated to a four-speed gearbox. A Borg-Warner Model 35 three-speed automatic transmission
14399-473: Was the high government taxes imposed by the government in relation to this class of vehicle - the automobile taxation system of South Korea greatly favours engines of less than 1.5 litres displacement. The car was also perceived to suffer from high fuel consumption, while the suspension was seen as unsuitable for Korean roads. Due to poor Chevrolet 1700 sales, the car was revised as the Camina in 1976, receiving
14520-575: Was used in several of the company's sports cars. The 1906–1908 Ford Model K luxury car used a 405 cu in (6.6 L) straight-six petrol engine and was the only Ford six-cylinder passenger car engine until the 1940s. The Ford flathead I6 was produced from 1941 until 1951, followed by the Ford OHV I6 overhead valve engine from 1952 through 1964, then the Ford Thriftpower Six overhead valve engine from 1960 until 1982, and
14641-742: Was used in the Ford Zephyr executive car and several other models from 1951 to 1966. The Triumph I6 overhead valve straight-six petrol engine was produced from 1960 to 1977 and debuted in the Standard Vanguard Six sports saloon. The Leyland PE166 engine was loosely based on the Triumph design and was produced from 1977 to 1986. The 1972–1977 TVR 2500M sports car was powered by the Triumph I6 engine. Then, from 1999 to 2007, TVR's own TVR Speed Six dual overhead camshaft engine
