The automotive industry comprises a wide range of companies and organizations involved in the design , development , manufacturing , marketing , selling , repairing , and modification of motor vehicles . It is one of the world's largest industries by revenue (from 16% such as in France up to 40% to countries such as Slovakia).
125-691: Audi AG ( German: [ˈaʊ̯di ʔaːˈɡeː] ) is a German automotive manufacturer of luxury vehicles headquartered in Ingolstadt , Bavaria, Germany. A subsidiary of the Volkswagen Group , Audi produces vehicles in nine production facilities worldwide. The origins of the company are complex, dating back to the early 20th century and the initial enterprises ( Horch and the Audiwerke ) founded by engineer August Horch . Two other manufacturers ( DKW and Wanderer ) also contributed to

Such designs appear to have been limited to diesel engines such as the Detroit 71 series , marine engines, and outboard motors. Some of the 120 possible crankshaft configurations have useful properties. Still, all of them have a rocking imbalance that may or may not require a balance shaft, depending on
375-626: A 1.8 L flathead petrol engine used by the Opel 8/40 PS . The displacement of this engine was expanded as it was used in later models such as the Opel Kapitän and Opel Admiral , with later versions switching to an overhead valve (pushrod) design. In 1968, the straight-six versions of the Opel CIH engine were introduced, initially using a single overhead camshaft (SOHC) with some later versions using double overhead camshafts (DOHC). Production of
500-404: A 2,612 cc inline-four engine model Type A, followed by a 3,564 cc model, as well as 4,680 cc and 5,720 cc models. These cars were successful even in sporting events. The first six-cylinder model Type M, 4,655 cc appeared in 1924. August Horch left the Audiwerke in 1920 for a high position at the ministry of transport, but he was still involved with Audi as a member of
625-531: A V6 engine replaced it. The Nissan TB overhead valve engine was introduced in 1987 and produced alongside the other straight-six engines. The six-cylinder versions of the Prince G engine were introduced in 1963 and remained in production until 1969, three years after Prince's merger with Nissan. The 1969–1973 Nissan S20 dual overhead camshaft engine (used in the Nissan Fairlady and first generation of

According to a J.D. Power study, emerging markets accounted for 51 percent of the global light-vehicle sales in 2010. The study, performed in 2010 expected this trend to accelerate. However, more recent reports (2012) confirmed
875-400: A centre differential . Commonly referred to as the "Ur-Quattro" (the " Ur- " prefix is a German augmentative used, in this case, to mean 'original' and is also applied to the first generation of Audi's S4 and S6 Sport Saloons, as in "UrS4" and "UrS6"), few of these vehicles were produced (all hand-built by a single team), but the model was a great success in rallying. Prominent wins proved
1000-650: A device requiring the driver to press the brake pedal before shifting out of park. A legacy of the Audi 5000 and other reported cases of sudden unintended acceleration are intricate gear stick patterns and brake interlock mechanisms to prevent inadvertent shifting into forward or reverse. It is unclear how the defects in the idle-stabilization system were addressed. Audi's U.S. sales, which had reached 74,061 in 1985, dropped to 12,283 in 1991 and remained level for three years,—with resale values falling dramatically. Audi subsequently offered increased warranty protection and renamed

The decision to dispose of the Auto Union business was based on its lack of profitability. Ironically, by the time they sold the business, it also included a large new factory and near production-ready modern four-stroke engine, which would enable
1750-597: A straight six version of the Chrysler flathead petrol engine. This was replaced by the 1959–2000 Chrysler Slant-6 overhead valve straight-six petrol engine, which was so named due to the 30-degree angle used to reduce the height of the engine (with the trade-off of a wider engine). The Slant-6 was released in the Dodge Dart economy car and used in many models until a V6 engine replaced it after 30 years. The Chevrolet Stovebolt overhead valve straight-six petrol engine
1875-496: A straight-six engine compare favorably with the more common straight-four engines and V6 engines , which experience significant secondary dynamic imbalance, resulting in engine vibration. As engine reciprocating forces increase with the cube of piston bore, the straight-six is a preferred configuration for large truck engines. An even-firing six-cylinder two-stroke engine requires ignitions at 60° intervals, or else it would run with simultaneous ignitions and be no smoother than
2000-415: A straight-six was the 1961–1969 Alfa Romeo 2600 executive car before the company switched to V6 engines. Mercedes-Benz's history of straight-six engines began with the 1913 Mercedes D.I aircraft engine. The first automotive straight-six engine was the 1924–1929 Daimler M836 3.9 L petrol engine. Following World War 2, Mercedes resumed production of straight-six engines with the 1951 introduction of

These were the twenty largest manufacturers by production volume in 2012 and 2013, or the 21 largest in 2011 (before the Fiat-Chrysler merger ), of which the fourteen largest as of 2011 were in the top 14 in 2010, 2008 and 2007 (but not 2009, when Changan and Mazda temporarily degraded Chrysler to 16th place). The eighteen largest as of 2013 have remained in
8250-428: The U.S. had one car per 4.87 persons. After 1945, the U.S. produced around three-quarters of the world's auto production. In 1980, the U.S. was overtaken by Japan and then became a world leader again in 1994. Japan narrowly passed the U.S. in production during 2006 and 2007, and in 2008 also China , which in 2009 took the top spot (from Japan) with 13.8 million units, although the U.S. surpassed Japan in 2011, to become
8375-488: The United States fell after a series of recalls from 1982 to 1987 of Audi 5000 models associated with reported incidents of sudden unintended acceleration linked to six deaths and 700 accidents. At the time, NHTSA was investigating 50 car models from 20 manufacturers for sudden surges of power. A 60 Minutes report aired 23 November 1986, featuring interviews with six people who had sued Audi after reporting unintended acceleration, showing an Audi 5000 ostensibly suffering
8500-429: The United States for the 1970 model year. That same year, the mid-sized car that NSU had been working on, the K70 , originally intended to slot between the rear-engined Prinz models and the futuristic NSU Ro 80 , was instead launched as a Volkswagen. After the launch of the Audi 100 of 1968, the Audi 80 /Fox (which formed the basis for the 1973 Volkswagen Passat ) followed in 1972 and the Audi 50 (later rebadged as
8625-514: The West German versions. West and East German models were equipped with the traditional and renowned DKW two-stroke engines. The Zwickau plant later manufactured the infamous Trabant until 1991, after it was acquired by the Volkswagen Group following the reunification of Germany, and has since been substantially rebuilt. In 2021, production of the Audi Q4 e-tron began at the plant, marking the return of Audis being manufactured at Zwickau after over 80 years. A new West German headquartered Auto Union
8750-430: The affected models—with the 5000 becoming the 100 and 200 in 1989—and reached the same sales levels again only by model year 2000. A 2010 BusinessWeek article—outlining possible parallels between Audi's experience and 2009–2010 Toyota vehicle recalls —noted a class-action lawsuit filed in 1987 by about 7,500 Audi 5000-model owners remains unsettled and remains contested in Chicago 's Cook County after appeals at
8875-525: The application. The six pistons with six unique phases cannot be "paired" as in the four-stroke case. The Detroit engines used a configuration that, once the primary rocking couple was balanced out, was also perfectly balanced at all other rocking couples until the 6th order. Mercury came to use a configuration that canceled only the primary rocking couple and was run without a balancer. The reciprocating masses of all configurations are still imbalanced at only 6th-order and up in their plane of motion. Still,
9000-486: The automotive industry, safety means that users, operators, or manufacturers do not face any risk or danger coming from the motor vehicle or its spare parts. Safety for the automobiles themselves implies that there is no risk of damage. Safety in the automotive industry is particularly important and therefore highly regulated. Automobiles and other motor vehicles have to comply with a certain number of regulations, whether local or international, in order to be accepted on
9125-465: The balance of kinetic energy exchange between pistons has improved to a residual 6th-order-and-up inertial torque oscillation compared with the four-stroke design being imbalanced at 3rd-order and up. Crankshafts for straight-six engines usually have either four main bearings (i.e., a bearing in between each pair of crankpins and one at each end) or seven main bearings (i.e., a bearing between every crankpin): The first production straight-six engine
9250-502: The biggest contributor to parent Volkswagen Group's nine-month operating profit of €1.5 billion, while the other marques in Group such as Bentley and SEAT had suffered considerable losses. May 2011 saw record sales for Audi of America with the new Audi A7 and Audi A3 TDI Clean Diesel. In May 2012, Audi reported a 10% increase in its sales—from 408 units to 480 in the last year alone. Audi manufactures vehicles in seven plants around
9375-473: The board of trustees. In September 1921, Audi became the first German car manufacturer to present a production car, the Audi Type K, with left-handed drive. Left-hand drive spread and established dominance during the 1920s because it provided a better view of oncoming traffic, making overtaking safer when driving on the right. In August 1928, Jørgen Rasmussen , the owner of Dampf-Kraft-Wagen (DKW), acquired
9500-510: The dormant Horch trademark and the Düsseldorf factory which became a Mercedes-Benz van assembly plant. Eighteen months later, Volkswagen bought complete control of Ingolstadt, and by 1966 were using the spare capacity of the Ingolstadt plant to assemble an additional 60,000 Volkswagen Beetles per year. Two-stroke engines became less popular during the 1960s as customers were more attracted to the smoother four-stroke engines. In September 1965,
9625-484: The fatally flawed NSU Ro80 went out of production in 1977, spelling the effective end of the NSU brand. Production of the Audi 100 had been steadily moved from Ingolstadt to Neckarsulm as the 1970s had progressed, and by the appearance of the second generation C2 version in 1976, all production was now at the former NSU plant. Neckarsulm from that point onward would produce Audi's higher-end models. The Audi image at this time
9750-519: The five-cylinder engine was a successful and robust powerplant, it was still a little too different for the target market. With the introduction of an all-new Audi 100 in 1992, Audi introduced a 2.8L V6 engine . This engine was also fitted to a face-lifted Audi 80 (all 80 and 90 models were now badged 80 except for the USA), giving this model a choice of four-, five-, and six-cylinder engines, in saloon , coupé and convertible body styles. The five-cylinder
9875-510: The foundation of Auto Union in 1932. The modern Audi era began in the 1960s, when Auto Union was acquired by Volkswagen from Daimler-Benz . After relaunching the Audi brand with the 1965 introduction of the Audi F103 series, Volkswagen merged Auto Union with NSU Motorenwerke in 1969, thus creating the present-day form of the company. The company name is based on the Latin translation of
10000-574: The historical trademarks and intellectual property of the original constituent companies (the exception being Horch, which had been retained by Daimler-Benz after the VW takeover), and to operate Audi's heritage operations. In 1986, as the Passat-based Audi 80 was beginning to develop a kind of "grandfather's car" image, the type 89 was introduced. This completely new development sold extremely well. However, its modern and dynamic exterior belied
10125-433: The ideas of Felix Wankel . In 1967, the new NSU Ro 80 was a car well ahead of its time in technical details such as aerodynamics, light weight, and safety. However, teething problems with the rotary engines put an end to the independence of NSU. The Neckarsulm plant is now used to produce the larger Audi models A6 and A8 . The Neckarsulm factory is also home of the " quattro GmbH " (from November 2016 " Audi Sport GmbH "),
10250-488: The list below) currently possess the capability to design original production automobiles from the ground up, and 17 countries (listed below) have at least one million produced vehicles a year (as of 2023). These were the ten largest manufacturers by production volume as of 2017, of which the eight largest were in the top 8 positions since Fiat's 2013 acquisition of the Chrysler Corporation (although
10375-513: The low performance of its base engine, and its base package was quite spartan (even the passenger-side mirror was an option). In 1987, Audi put forward a new and very elegant Audi 90 , which had a much superior set of standard features. In the early 1990s, sales began to slump for the Audi 80 series, and some basic construction problems started to surface. Through the early 1990s, Audi began to shift its target market upscale to compete against German automakers Mercedes-Benz and BMW . This began with
10500-700: The majority of shares in Audiwerke AG. In the same year, Rasmussen bought the remains of the U.S. automobile manufacturer Rickenbacker , including the manufacturing equipment for 8-cylinder engines. These engines were used in Audi Zwickau and Audi Dresden models that were launched in 1929. At the same time, 6-cylinder and 4-cylinder ( the "four" with a Peugeot engine) models were manufactured. Audi cars of that era were luxurious cars equipped with special bodywork. In 1932, Audi merged with Horch , DKW, and Wanderer , to form Auto Union AG, Chemnitz . It
10625-545: The market. The standard ISO 26262 , is considered one of the best practice frameworks for achieving automotive functional safety . In case of safety issues, danger, product defect , or faulty procedure during the manufacturing of the motor vehicle, the maker can request to return either a batch or the entire production run. This procedure is called product recall . Product recalls happen in every industry and can be production-related or stem from raw materials. Product and operation tests and inspections at different stages of
10750-643: The opposite; namely that the automotive industry was slowing down even in BRIC countries. In the United States, vehicle sales peaked in 2000, at 17.8 million units. In July 2021, the European Commission released its " Fit for 55 " legislation package, which contains important guidelines for the future of the automotive industry; all new cars on the European market must be zero-emission vehicles from 2035. The governments of 24 developed countries and
10875-780: The region. Brandenburg's Economy Minister Joerg Steinbach said that while water supply was sufficient during the first stage, more would be needed once Tesla expands the site. The factory would nearly double the water consumption in the Gruenheide area, with 1.4 million cubic meters being contracted from local authorities per year — enough for a city of around 40,000 people. Steinbach said that the authorities would like to drill for more water there and outsource any additional supply if necessary. 1960s : Post-war increase 1970s : Oil crisis and tighter safety and emission regulation 1990s : Production started in NICs . 2000s : Rise of China as
11000-554: The release of the Audi V8 in 1990. It was essentially a new engine fitted to the Audi 100/200, but with noticeable bodywork differences. Most obvious was the new grille that was now incorporated in the bonnet. By 1991, Audi had the four-cylinder Audi 80, the 5-cylinder Audi 90 and Audi 100 , the turbocharged Audi 200 and the Audi V8. There was also a coupé version of the 80/90 with both four- and five-cylinder engines. Although
11125-466: The room. Several times he looked like he was on the verge of saying something but would just swallow his words and continue working, until he finally blurted out, "Father – audiatur et altera pars ... wouldn't it be a good idea to call it audi instead of horch ?". Horch in German means 'hark' or 'hear', which is audi in the singular imperative form of audire —'to listen'—in Latin. The idea
11250-840: The second generation Q5. From 2002 up to 2003, Audi headed the Audi Brand Group, a subdivision of the Volkswagen Group's Automotive Division consisting of Audi, Lamborghini and SEAT, which was focused on sporty values, with the marques' product vehicles and performance being under the higher responsibility of the Audi brand. Automotive manufacturer The word automotive comes from the Greek autos (self), and Latin motivus (of motion ), referring to any form of self-powered vehicle. This term, as proposed by Elmer Sperry (1860–1930), first came into use to describe automobiles in 1898. The automotive industry began in
11375-461: The second-largest automobile industry. In 2023, China had for the first time in history more than 30 million produced vehicles a year, after reaching 29 million for the first time in 2017 and 28 million the year before. From 1970 (140 models) over 1998 (260 models) to 2012 (684 models), the number of automobile models in the U.S. has grown exponentially. Safety is a state that implies being protected from any risk, danger, damage, or cause of injury. In
11500-404: The surname of the founder, August Horch . Horch , meaning 'listen', becomes audi in Latin. The four rings of the Audi logo each represent one of four car companies that banded together to create Audi's predecessor company, Auto Union. Audi's slogan is Vorsprung durch Technik , which is translated as 'Progress through Technology'. Audi, along with German brands BMW and Mercedes-Benz ,
11625-442: The time: "Audi idle-stabilization systems were prone to defects which resulted in excessive idle speeds and brief unanticipated accelerations of up to 0.3g [which is similar in magnitude to an emergency stop in a subway car]. These accelerations could not be the sole cause of [(long-duration) sudden acceleration incidents (SAI)], but might have triggered some SAIs by startling the driver. The defective idle-stabilization system performed
11750-500: The top 20 as of 2017, except Mitsubishi which fell out of top 20 in 2016, while Geely fell out of the top 20 in 2014 and 2015 but re-entered it in 2016. It is common for automobile manufacturers to hold stakes in other automobile manufacturers. These ownerships can be explored under the detail for the individual companies. Notable current relationships include: Straight-six engine The straight-six engine (also referred to as an inline-six engine ; abbreviated I6 or L6)
11875-579: The use of frugal three-cylinder engines. The A2 was extremely aerodynamic and was designed around a wind tunnel . The Audi A2 was criticised for its high price and was never really a sales success but it planted Audi as a cutting-edge manufacturer. The model, a Mercedes-Benz A-Class competitor, sold relatively well in Europe. However, the A2 was discontinued in 2005 and Audi decided not to develop an immediate replacement. The next major model change came in 1995 when
12000-421: The viability of all-wheel-drive racecars, and the Audi name became associated with advances in automotive technology. In 1985, with the Auto Union and NSU brands effectively dead, the company's official name was now shortened to simply Audi AG . At the same time the company's headquarters moved back to Ingolstadt and two new wholly owned subsidiaries; Auto Union GmbH and NSU GmbH , were formed to own and manage
12125-457: The world's largest-producing country in 2009. 2010s : India overtakes Korea, Canada, Spain to become 5th largest automobile producer. 2013 : The share of China (25.4%), India, Korea, Brazil, and Mexico rose to 43%, while the share of United States (12.7%), Japan, Germany, France, and United Kingdom fell to 34%. The OICA counts over 50 countries that assemble, manufacture, or disseminate automobiles. Of those, only 15 countries ( boldfaced in
12250-563: The world, some of which are shared with other VW Group marques although many sub-assemblies such as engines and transmissions are manufactured within other Volkswagen Group plants. Audi's two principal assembly plants in Germany are: Outside of Germany, Audi produces vehicles at: In September 2012, Audi announced the construction of its first North American manufacturing plant in Puebla , Mexico. This plant became operative in 2016 and produces
12375-498: Was a conservative one, and so, a proposal from chassis engineer Jörg Bensinger was accepted to develop the four-wheel drive technology in Volkswagen 's Iltis military vehicle for an Audi performance car and rally racing car. The performance car, introduced in 1980, was named the " Audi Quattro ", a turbocharged coupé which was also the first German large-scale production vehicle to feature permanent all-wheel drive through
12500-570: Was deleted from the commercial register. These actions had the effect of liquidating Germany's Auto Union AG. The remains of the Audi plant of Zwickau became the VEB (for "People Owned Enterprise") Automobilwerk Zwickau or AWZ (in English: Automobile Works Zwickau). The former Audi factory in Zwickau restarted assembly of the pre-war models in 1949. These DKW models were renamed to IFA F8 and IFA F9 and were similar to
12625-538: Was during this period that the company offered the Audi Front that became the first European car to combine a six-cylinder engine with front-wheel drive. It used a power train shared with the Wanderer, but turned 180 degrees, so that the drive shaft faced the front. Before World War II , Auto Union used the four interlinked rings that make up the Audi badge today, representing these four brands. However, this badge
12750-571: Was enthusiastically accepted by everyone attending the meeting. On 25 April 1910 the Audi Automobilwerke GmbH Zwickau (from 1915 on Audiwerke AG Zwickau ) was entered in the company's register of Zwickau registration court. The first Audi automobile, the Audi Type A 10/22 hp (16 kW) Sport-Phaeton, was produced in the same year, followed by the successor Type B 10/28PS in the same year. Audi started with
12875-469: 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
13000-589: 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
13125-412: 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
13250-423: 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
13375-496: Was hostile to the idea of Auto Union as a standalone entity producing its own models having acquired the company merely to boost its own production capacity through the Ingolstadt assembly plant—to the point where Volkswagen executives ordered that the Auto Union name and flags bearing the four rings were removed from the factory buildings. Then VW chief Heinz Nordhoff explicitly forbade Auto Union from any further product development. Fearing that Volkswagen had no long-term ambition for
13500-531: 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
13625-407: 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
13750-670: 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,
13875-647: 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
14000-581: Was launched in Ingolstadt with loans from the Bavarian state government and Marshall Plan aid. The reformed company was launched 3 September 1949 and continued DKW's tradition of producing front-wheel drive vehicles with two-stroke engines. This included production of a small but sturdy 125 cc motorcycle and a DKW delivery van, the DKW F89 L at Ingolstadt. The Ingolstadt site was large, consisting of an extensive complex of formerly military buildings which
14125-527: 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
14250-613: 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
14375-573: 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
14500-419: 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
14625-605: 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
14750-532: 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,
14875-479: 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
15000-467: 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
15125-662: Was soon dropped as a major engine choice; however, a turbocharged 220 PS (160 kW; 220 hp) version remained. The engine, initially fitted to the 200 quattro 20V of 1991, was a derivative of the engine fitted to the Sport Quattro . It was fitted to the Audi Coupé , named the S2 , and also to the Audi 100 body, and named the S4 . These two models were the beginning of the mass-produced S series of performance cars. Sales in
15250-529: Was suitable for administration as well as vehicle warehousing and distribution, but at this stage there was at Ingolstadt no dedicated plant suitable for mass production of automobiles: for manufacturing the company's first post-war mass-market passenger car plant capacity in Düsseldorf was rented from Rheinmetall-Borsig . It was only ten years later, after the company had attracted an investor, when funds became available for construction of major car plant at
15375-575: 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
15500-742: 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
15625-436: Was used only on Auto Union racing cars in that period while the member companies used their own names and emblems. The technological development became more and more concentrated and some Audi models were propelled by Horch- or Wanderer-built engines. Reflecting the economic pressures of the time, Auto Union concentrated increasingly on smaller cars through the 1930s, so that by 1938 the company's DKW brand accounted for 17.9% of
