Что означает v12 на автомобилях

A V12 engine is a twelve-cylinder piston engine where two banks of six cylinders are arranged in a V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines.

The first V12 engine was built in 1904 for use in racing boats. Due to the balanced nature of the engine and the smooth delivery of power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, following which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s.

Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars.

Design[edit]

Balance and smoothness[edit]

Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary and secondary engine balance. A four-stroke V12 engine has even firing order at V-angles of 60, 120, or 180 degrees^[1] Many V12 engines use a V-angle of 60 degrees between the two banks of cylinders.^[2] V12 engines with other V-angles have been produced, sometimes using split crankpins to reduce the unbalanced vibrations. The drawbacks of V12 engines include extra cost, complexity, friction losses, and external size and weight, compared with engines containing fewer cylinders.

At any given time, three of the cylinders in a V12 engine are in their power stroke, which increases the smoothness of the power delivery by eliminating gaps between power pulses.

A V12 engine with a 180 degree V-angle is often called a flat-twelve engine. These are also sometimes called ‘boxer twelve’ engines, however this terminology is incorrect for the majority of 180-degree V12 engines, since they use shared crankpins and are therefore not configured as boxer engines.^[3]

Theoretically, the rotating parts of a V12 racing engine could be lighter than a crossplane V8 engine of similar displacement due to the V12 engine not requiring counterweights on the crankshaft or as much inertial mass for the flywheel. In addition, the exhaust system of a V12 engine is much simpler than would be required for a crossplane V8 engine to achieve pulsed exhaust gas tuning. However, the use of V12 engines in motor racing is uncommon in the 21st century.

Size and displacement[edit]

A 60-degree V12 engine is typically narrower than a 90-degree V6 or V8 engine of similar displacement. However, the V12 engine is usually longer than V6 and V8 engines. The added length often makes it difficult to fit a V12 engine into a passenger car, but the length is not typically a problem for trucks and stationary applications. Due to its narrower width, the V12 is common as locomotive, armoured tank, and marine engines. In these applications, the width of the engine is constrained by tight railway clearances or street widths, while the length of the vehicle is more flexible.

In twin-propeller boats, two V12 engines can be narrow enough to sit side by side, while three V12 engines are sometimes used in high-speed three-propeller configurations. Large, fast cruise ships can have six or more V12 engines. In historic piston-engine fighter and bomber aircraft, the long, narrow V12 configuration used in high-performance aircraft made them more streamlined than other engines, particularly the short, wide radial engine.

Usage in marine vessels[edit]

The first V-engine (a V-twin design) was built by Daimler in 1889,^[4] then the first V8 engine was built by Antoinette in 1903. These were followed by the first V12 engine in 1904, which was built by Putney Motor Works in London for use in racing boats.^[5] Known as the «Craig-Dörwald» engine after Putney’s founding partners,^[6] the V12 engine was based on Putney’s existing two-cylinder engine with a flathead design, a V-angle of 90 degrees and an aluminium crankcase. As in many marine engines, the camshaft could be slid longitudinally to engage a second set of cams, giving valve timing that reversed the engine’s rotation to achieve astern propulsion.^[7] The engine had a displacement of 18.4 L (1,120 cu in) a weight of 430 kg (950 lb) and developed 12 m (40 ft) racing boats, but little is known of its racing achievements.^[5]

Two more V12s appeared in the 1909-1910 motor boat racing season. The Lamb Boat & Engine Company in the United States built a 25.5 L (1,559 cu in) engine for the company’s 10 m (32 ft) ‘Lamb IV’ boat. The Orleans Motor Company built a massive 56.8 L (3,464 cu in) flathead V12 engine with a power output quoted as «nearly 298 kW (400 bhp)». In 1914, Panhard built two 38.6 L (2,356 cu in) V12 engines with four valves per cylinder, which were designed for use in racing boats.^[5]

Large V12 diesel engines are common in modern cruise ships, which may have up to six such engines.^[8] An example of a currently produced V12 marine engine is the Wärtsilä 46F engine, where the V12 version has a displacement of 1,157 L (70,604 cu in) and a power output of 14,400 kW (19,300 hp).^[9]

Usage in airplanes[edit]

1900s to 1930s[edit]

Five years after the first V12 engine was introduced, Renault introduced the first V12 engine for aircraft in 1909. This engine had a V-angle of 60 degrees, air cooling and an intake over exhaust (F-head) valve arrangement. It had a displacement of 12.2 L (740 cu in), a weight of 350 kg (772 lb) and produced 103 kW (138 hp) at 1,800 rpm. The propeller was driven from the front end of the camshaft, thus spinning the propeller speed at half the speed of a typical crankshaft driven propeller, in order to improve the propeller efficiency.^[5] The Renault engine was closely mimicked by the RAF 4 and its derivatives,^{[citation needed]} which was used by various British military aircraft during World War I. The RAF 4 engine had a displacement of 13.2 L (806 cu in), weighed 289 kg (637 lb) and produced 104 kW (140 hp) at 1,800 rpm.

In March 1914, a prototype version of the Sunbeam Mohawk V12 engine was unveiled in the United Kingdom, based on the ‘Toodles V’ motor racing engine. The production version was rated at 168 kW (225 hp) at 2,000 rpm, making it the most powerful airplane engine in Great Britain at the outbreak of World War I.^[5] During and after World War I, various companies in the United States produced the Liberty L-12 engine. In Austria, the Austro Daimler V12 engines were used by the large flying boats of the Naval Air Force and produced up to 257 kW (345 hp). By the end of World War I, V12s were well established in aviation, powering some of the newest and largest fighter and bomber airplanes.

After World War I, many Zeppelins used V12 engines built by Maybach and Daimler. V12 engines powered the first transatlantic crossings by the Curtiss NC flying boats (using four Liberty L-12 engines), the first non-stop transatlantic crossing in a Vickers Vimy (using two Rolls-Royce Eagle engines) and the first transatlantic crossing by an airship in the R-34 class airship (using five Sunbeam Maori engines).

1940s to present[edit]

V12 engines reached their apogee during World War II with engines such as the British Rolls-Royce Merlin and Rolls-Royce Griffon, the Soviet Klimov VK-107 and Mikulin AM-38, the American Allison V-1710, and the German Daimler-Benz DB 600 and Junkers Jumo. These engines generated about 750 kW (1,000 hp) at the beginning of the war and over 1,100 kW (1,500 hp) at their ultimate evolution stage. This rapid increase in power outputs was due to technology such as multi-speed superchargers and high octane fuels, and the V12 layout was commonly adopted due to its low vibrations so that the powerful engines did not tear apart the light airframes of fighters.

The Allied forces used V12 engines with an «upright» design, while many German engines (aside from the BMW VI, which was designed prior to World War II), used an inverted engine design, which had a lower centre of gravity and improved pilot visibility for single-engined designs. The only American-design inverted V12 engine of any type to see even limited service in World War II was the air-cooled Ranger V-770, which was used in aircraft that were only used for training purposes within the United States, such as the Fairchild AT-21 Gunner.

The Rolls-Royce Merlin V12 engine was used in several British aircraft including the Hawker Hurricane and Supermarine Spitfire fighters, and the Avro Lancaster and de Havilland Mosquito bombers. The Hurricane and Spitfire played vital roles in the Battle of Britain. The long, narrow configuration of the V12 contributed to good aerodynamics, while its smoothness allowed its use with relatively light and fragile airframes.

In the United States, the Rolls-Royce Merlin engine was produced under license by Packard Motor Car Company, which was used in the P-51 Mustang fighter. This engine was also incorporated into some models of the Curtiss P-40, specifically the P-40F and P-40L. Packard Merlins powered Canadian-built Hurricane, Lancaster, and Mosquito aircraft, as well as the UK-built Spitfire Mark XVI, which was otherwise the same as the Mark IX with its British-built Merlin. The Allison V-1710 was the only liquid-cooled V12 engine designed in the United States that was used on active service during World War II. It was initially used in the P-38 Lightning, but the turbosupercharger system required bulky ductwork and had poor high-altitude performance. In 1943, a version using a more conventional mechanical supercharger began production.

After World War II, V12 engines became generally obsolete in aircraft due to the introduction of turbojet and turboprop engines that had more power for their weight, and fewer complications.

Usage in automobiles[edit]

In automobiles, V12 engines are less common than engines with fewer cylinders, due to their size, complexity, and cost. They have been mostly used for expensive sports and luxury cars thanks to their power, smooth operation, and distinctive sound.

1910s[edit]

One of the earliest recorded uses of V12 engines in automobiles was in October 1913, when a custom-built racing car competed at the Brooklands circuit in the United Kingdom. The car was entered by Louis Coatalen, who was chief engineer of the Sunbeam Motor Car Company. It was named ‘Toodles V’ (after Coatalen’s pet name for his wife) and achieved several speed records in 1913 and 1914.^[5] The V12 engine had a displacement of 9.0 L (549 cu in), an aluminum crankcase, iron cylinders with L-shaped combustion chambers, a cam-in-block valvetrain and a V-angle of 60 degrees. Each bank of the engine consisted of two-cylinder blocks with three cylinders each. Valve clearance was set by grinding the relevant parts, the engine lacking any easy means of adjustment. This reflected the intention for the engine to be later used in aircraft since any adjustment method that could go wrong in flight was to be avoided. As initially built, the V12 was rated at 150 kW (200 bhp) at 2,400 rpm and weighed approximately 340 kg (750 lb).

Amongst the first production cars to use a V12 engine were the 1915 Packard Twin Six,^[10][11] the 1915 National V12 engine^{[citation needed]} and the 1917 Weidely Pathfinder;^[12] all of which were built in the United States.

1920s to 1940s[edit]

During the late 1920s, the number of marques offering V12 engines for their passenger cars increased and peaked in the 1930s. The lack of vibration and sound, inherent smoothness, and increased power were cited as key benefits for V12 engines.^[13] Automobile petrol produced in the 1920s and 1930s had lower octane rating, leading to lower engine performance ratings, and vibration isolating engine mounts were rarely fitted to the passenger cars in the 1920s and the early 1930s. Adding more cylinders to the engine was one of several techniques for performance increase.

European passenger cars with V12 engines were:

• Fiat 520 ‘Superfiat’ (1921–1922)
• Daimler Double-Six (several models built at different times from 1926 to 1938)
• Horch 12 (1931–1934)
• Hispano-Suiza J12 (1931–1938)
• Maybach Zeppelin DS 7 (1928–1930) and DS 8 (1930–1938)
• Rolls-Royce Phantom III (1936–1939)
• Tatra 80 (1931–1935)

American passenger cars with V12 engines were:

• Auburn V-12 Speedster (1932–1934)^[14]
• Cadillac V-12 (1931–1937)
• Franklin V-12 (1932–1934)^[15]
• Lincoln K-series/Model K (1931–1940)
  • Custom (1941–1942)
  • Continental (1940–1948)
• Lincoln-Zephyr V-12 (1936–1942)
  • H-series (1946–1948)
• Packard Twin Six (1916–1923 and 1932)
  • Packard 905 (1916–1923)
  • Packard Twelve (1933–1939)
• Pierce-Arrow Twelve (1932–1938)^[16]
  • Pierce Silver Arrow (1933)

The economic hardships caused the Great Depression meant that all American automakers except for Lincoln had discontinued production of V12 engines by the end of the 1930s. Lincoln themselves would cease V12 production in 1948, and no American automaker has built V12 engines since. Improvements in engine design, namely combustion chamber, piston form, fuel delivery system, and such enabled the lighter and cheaper V8 engines to surpass V12 engines in performance.

1945 to 1960s[edit]

Following the end of the Second World War, the economic austerity and changes in taste in many European countries led to the demise of luxury automobiles with V12 engines in the 1940s and 1950s. Lincoln continued the limited production of luxury cars with V12 engines from 1946 to 1948. The American manufacturers focused on continuously improving V8 engines and their performances through the 1950s, leading to the first «horsepower war» in the 1960s.

In Italy, Enzo Ferrari introduced his first passenger car, Ferrari 166 Inter, in 1948 and fitted it with 2.0 L (122 cu in) Colombo V12 engine. Dissatisfied with the reliability and crudeness of his Ferrari 250 GT, Ferruccio Lamborghini wanted to develop his own passenger cars that were more cultured and more reliable than the cars produced by Ferrari. His first passenger car, a grand tourer, was 350 GT with 3.5 L (214 cu in) DOHC engine. Both manufacturers have a long history of producing vehicles with V12 engines, which continues uninterrupted to this day.

Cadillac experimented with V12 engines in 1963 and 1964 as a potential engine option for its first-ever front-wheel-drive car, Cadillac Eldorado. However, Cadillac was unsatisfied with the performance of its V12 engine, having little advantage over the large displacement V8 that was cheaper to enlarge for more power.^[17]

1970s to present[edit]

In Europe, several manufacturers added V12 engines to their line-up, as listed below:

• Jaguar: The Jaguar V12 engine was an all-aluminium SOHC design with displacements of 5.3–6.0 L (323–366 cu in) that was produced from 1971 to 1997 in the E-Type, XJS, and XJ. The first application for the engine was a 5.3 litre version used in the Jaguar E-Type sports car.^[18][19][20]
• BMW: Production of V12 engines began with the BMW M70 SOHC engine introduced in the 1987 E32 7 Series luxury sedan. The engine was also used in the E31 8 Series. The engine was upgraded to a DOHC V12 engine in 2003, then to a turbocharged DOHC V12 engine which has been in production from 2008 to the present in the 7 Series.^[21][22][23] BMW V12 engines have also been used in several Rolls-Royce models, beginning in 1998 with the Rolls-Royce Silver Seraph.
• Mercedes-Benz: The company’s first V12 engine was the M120, a 6.0 L (366 cu in) DOHC engine introduced in the 1991 Mercedes-Benz 600 SE luxury sedan. This engine was replaced by a SOHC V12 engine in 1998, then a turbocharged SOHC V12 engine which has been in production for 2003 to the present.^[24] Mercedes-Benz V12 engines have also been used in several Maybach models, beginning with the Maybach 57 and 62 in 2002.
• Aston Martin: The 1999 Aston Martin DB7 V12 Vantage used the company’s first V12 engine, a 5.9 L (362 cu in) DOHC design. Variations of this engine were used in the Vanquish, DB9, DBS V12, Rapide, Virage, and V12 Vantage. This engine was replaced by a turbocharged DOHC V12 engine, which was introduced in the Aston Martin DB11 and has been produced from 2016 to the present.
• Audi: The 2008–2012 Q7 SUV was powered by the Audi 6.0 V12 48v TDI engine, which was the first V12 diesel engine used in a production car.

In the United States, no mass-produced V12 engines have been built since the 1940s, with U.S. manufacturers preferring to use large displacement V8 engines instead.

Japanese manufacturers rarely produce engines with large displacements, therefore V12 engines are very rare. The sole Japanese V12 engine is the 1997–2016 Toyota GZ engine, a 5.0 L (305 cu in) DOHC design which was used in the Toyota Century limousine.^[25][26]

In China, the 2009 Hongqi HQE limousine, powered by a 6.0 L (366 cu in) DOHC V12 engine, is the sole Chinese car to be produced with a V12 engine.^{[citation needed][27]}

List of V12 production engines[edit]

Motor racing[edit]

V12 engines have often been used in Formula One, particularly from the 1966 season to the 1969 season. The first V12 engine used in Formula One was in the 1964 Honda RA271 racing car, and continued through to the 1968 Honda RA301 racing car. The 1966 season saw V12 engines become popular, with new V12 engines from Ferrari, Maserati, and Weslake. Ferrari’s engine debuted in the Ferrari 312 racing car and was used up to the 1975 Ferrari 312B, after which Ferrari switched to a flat-twelve engine. Maserati’s engine was introduced in the Cooper T81 and was used until the 1969 Cooper T86. The Weslake V12 engine was used from 1966 to 1968 and was introduced in the Eagle Mk1 racing car. BRM produced V12 engines from the 1968 BRM P133 racing car until the 1977 BRM P207. The Matra Sports V12 engine was introduced in the 1968 Matra MS11 racing car and used until the 1978 Ligier JS9. Few V12 engines were used in the following decade, with the exception of the Alfa Romeo V12 which was first used by the 1979 Brabham BT48 and then by Alfa Romeo until the 1982 Alfa Romeo 182.

A resurgence of V12 engines in Formula One began in 1989, with the introduction of the Ferrari 640 racing car. Ferrari continued to use V12 engines until the 1995 Ferrari 412 T2 became the last Formula One car to use a V12 engine. The Lamborghini LE3512 engine was used by various teams between 1989 and 1993. The Honda RA122-E engine was first used in the 1991 McLaren MP4/6 and was raced until the 1992 McLaren MP4/7A. The Yamaha OX99 engine was used in the 1990 Brabham BT59 through to the 1992 Brabham BT60. The most powerful naturally-aspirated V12 engine used in Formula One was the Tipo 043, used by Ferrari in 1994, which produced 850 hp (634 kW) @ 15,800 rpm.^[28]

In prototype sports car racing, the highly successful 2006–2008 Audi R10 TDI used a diesel twin-turbo V12 engine. The Peugeot 908 HDi FAP, introduced in 2007, also used a diesel twin-turbo V12 engine.

Usage in trucks[edit]

Several truck manufacturers have produced V12 diesel engines at various times. For example, the 1967–1982 Tatra T813, built in Czechoslovakia, used a 17.6 L (1,074 cu in) naturally aspirated V12 diesel engine, and the 1983–present Tatra T815 is available with a 19.0 L (1,159 cu in) V12 diesel engine in both naturally aspirated and turbocharged forms. In the United States, V12 versions of the 1938–1995 Detroit Diesel Series 71, the 1967–1999 Detroit Diesel Series 149 and the 1974–1995 Detroit Diesel Series 92 were produced. In Japan, Isuzu produced naturally aspirated V12 diesel engines from 14.0 L (854 cu in) to 22.0 L (1,343 cu in) in 1976–2000, for their heavy duty trucks: New Power, 810 and Giga.

Trucks using V12 gasoline (petrol) engines are rare, however several were produced in the United States from the 1930s until the 1970s. In 1931, American La France began producing firetrucks with V12 gasoline engines based on the Lycoming BB motor. In 1935, the V12 engine used by the Pierce Arrow luxury car was fitted to firetrucks built by Seagrave (with production continuing until 1970, since Seagrave purchased the equipment to manufacture the Pierce Arrow engines themselves). The 1960-1965 GMC Twin Six 11.5 L (702 cu in) gasoline V12 engine was basically the GMC 351 V6 engine, doubled, with four rocker covers and four exhaust manifolds.^[29] Peak power was only 250 hp (186 kW). However peak torque was 793 N⋅m (585 lb⋅ft).

Usage in railway locomotives[edit]

Many diesel locomotives use V12 engines. Examples include the 2.39 MW (3,200 hp) EMD 12-710 and the 3.28 MW (4,400 hp) GEVO-12 engine (used in the GE ES44AC North American locomotives).

V12 engines used in railway locomotives include:^{[citation needed]}

Usage in armoured fighting vehicles[edit]

The V12 is a common engine configuration for tanks and other armoured fighting vehicles. Some examples are:

• German HL120TRM gasoline engine, used on World War II Panzer III, Panzer IV and other tanks based on their chassis. The Maybach HL230 and its variants was used on the Panther, Tiger II, Jagdpanther, Jagdtiger (HL230 P30), then Tiger I and Sturmtiger which used the HL230 P45.
• British Rolls-Royce Meteor petrol engine (derived from the Rolls-Royce Merlin aero-engine) used in the World War II Cromwell tank and Comet tank, and later in the Centurion tank and Conqueror tank. The Challenger 2 tank was powered by the Perkins CV12-6A 26.6 L (1,623 cu in) diesel engine.
• Soviet Kharkiv model V-2 diesel engine, used in the World War II T-34 tank, Kliment Voroshilov tanks and IS-2 heavy tank. Model V-44 12-cyl. 38.88 L diesel used on the late-war T-44. V-12 diesel engine used on T-72, basically supercharged version of V-2.
• American Continental AV1790 engine, produced in gasoline and diesel variants, used on all versions of the Patton tank and on the M103 heavy tank. A prototype Chrysler A65 V12 engine was tested in the M4 Sherman tank in 1943, but it did not reach production.^[30][31]
• French Poyaud V12XS25 diesel engine used on the AMX-40. The Maybach HL 295 (reiteration of Maybach HL234, a later version of the Maybach HL230) was also used on the AMX-50 heavy tank.
• Japanese Mitsubishi SA12200VD air-cooled V-12 diesel engine used on the Type 97 Chi-Ha medium tank. A Mitsubishi Type 100 air-cooled V-12 diesel was also used on the Type 4 Ho-Ro self-propelled gun.

Двигатели о двенадцати цилиндрах и раньше считались большой редкостью, а теперь, в эпоху литровых моторов EcoBoost, становятся настоящими эксклюзивами и постепенно «вымирают», как динозавры. V12 – обычно прерогатива гиперкаров и автомобилей премиум-класса. Подержанный премиум быстро падает в цене и становится доступен многим. То, что раньше было уделом самых требовательных и обеспеченных покупателей, теперь может позволить себе любой. Причем нередко машины с двенадцатицилиндровыми двигателями оцениваются даже дешевле версий с «восьмерками» или «шестерками» – дело в прожорливости и дороговизне обслуживания. Мы выбрали автомобили с V12 (либо W12), которые продаются в каталоге «Автомалиновки», и изучили их.

Mercedes S600

Легендарный S600, символ девяностых годов. Каждый уважающий себя бандит мечтал о малиновом пиджаке, золотой цепочке толщиной с мизинец, огромном мобильнике и черном «шестисотом». Двигатель V12 как раз появился в кузове W140, расцвет которого пришелся на 1990-е годы. Предыдущее поколение (W126) имело топовый мотор V8 объемом 5,6 литра. Вероятно, в Mercedes решили добавить еще больше шика новому поколению, и поместили под капот флагманской версии шестилитровый двигатель с двенадцатью цилиндрами мощностью 394 л.с. Привод только задний, коробка передач – исключительно пятиступенчатый автомат. S600 в кузове W140 стоит сейчас не меньше 154 миллионов рублей.

Следующее поколение S-class (W220), выпускавшееся с 1998 по 2005 годы, не получило настолько культовый статус. Машина серьезно изменилась внешне, о наследственных чертах W140 можно забыть – автомобиль выглядит совсем иначе. Флагманский Mercedes получил AMG-версии, но найти их в продаже сложно. Среди «заряженных» моделей были S55 (360 либо 500 л.с.), S63 (444 л.с.) и S65 (612 л.с.) – две последние оснащались V12. Также существовала и обычная модификация с V12 под привычным индексом S600. Мощность составляла 367 л.с., после рестайлинга в 2003 году количество лошадиных сил увеличилось до 500 л.с. Цена за подержанный S600 (W220) начинается с 86 миллионов рублей.

Дебютировавший в 2005 году S-class (W221) вновь задал новые стандарты для седанов F-сегмента. Машина получила множество электронных помощников и систем, включая активный круиз-контроль, слежение за разметкой и считывание дорожных знаков. Также впервые на S-class появился опциональный полный привод, но не для всех модификаций. 

Версия S600 имела привод только на заднюю ось, это же касается и «заряженных» S63 и S65. S600 и S65 имеют под капотом двенадцатицилиндровые моторы мощностью 517 и 612 л.с. соответственно. W221 с V12 может стать вашим уже за 347 миллионов рублей.

С 2013 года выпускается новое поколение S-class, получившее индекс W222. В гамме двигателей остались версии с V12.

BMW 7-series

Баварский флагман получил V12 на втором поколении (Е32), которое выпускалось с 1986 по 1994 годы. Пятилитровый двигатель версии 750i развивал 300 лошадиных сил. Сейчас такую модификацию найти непросто, в отличие от последовавшей за E32 модели с индексом E38. Седан в этом кузове выпускался с 1994 по 2001 годы.

Получившая народное признание после фильма «Бумер» машина на постсоветском пространстве стала наряду с MercedesW140 символизировать криминальные девяностые. Двигатель M73 объемом 5,4 литра с компоновкой V12 развивал 326 л.с. Найти в хорошем состоянии E38 – задача крайне сложная. Машинам сейчас около двадцати лет, и жизнь успела неслабо их потрепать. Автомобиль в модификации 750i/750iL сейчас стоит 67 – 190 миллионов рублей. Также обратите внимание на редчайшую версию L7.

Следующее поколение 7-Series появилось в 2001 году и выпускалось до 2008 года. Автомобиль получил новый двигатель V12 объемом шесть литров для версий 760i и 760Li – с двенадцатью цилиндрами могла быть как обычная (E65), так и удлиненная (E66) на 140 мм модификация. Мотор N73 развивал 445 л.с., что позволяло двухтонному седану ускоряться с нуля до 100 км/ч за 5,5 секунды.

Машина с обычной колесной базой и двигателем V12 стоит не менее 183 миллионов рублей. Цены на удлиненные версии примерно такие же.

На пятом поколении 7-Series (F01/02), производившемся в 2008-2015 годах, появился опциональный привод, но версий с шестилитровым двигателем это не касается. Как и MercedesS-class, BMW 7-Series с V12 поставляется исключительно с RWD.

Автомобиль внешне получился более гармоничным по сравнению с предшественницей, которую нередко критиковали из-за спорных дизайнерских решений (особенно доставалось задней части машины). Мощность двигателя с двенадцатью цилиндрами увеличилась до 544 лошадиных сил, что позволило сбросить почти секунду при разгоне с 0 до 100 км/ч – теперь на это требуется 4,6 секунды. На момент написания этого материала объявлений о продаже 760i/760Li в этом кузове нет.

Модификацию с V12 в кузове F01/02 легко отличить по четырем патрубкам выхлопной системы – так они выглядят только у модели 760

С 2015 года началось производство 7-Series в кузове G11/G12. В ближайшее время ожидается появление модификации с V12.

Audi A8

Флагман Audi в кузове D2 дебютировал в 1994 году. Автомобиль, в отличие от конкурентов в лице MercedesS-class (W140) и 7-Series (E38), имел полный привод системы Quattro.

Audi использовала компоновку W12 – цилиндры расположены в четыре ряда, что делает его гораздо компактнее V12. Правда, это требует улучшенной системы охлаждения из-за близкого расположения цилиндров. На первом поколении A8 шестилитровый W12 развивал 420 лошадиных сил. В продаже на «Автомалиновке» таких модификаций D2 найти не удалось.

Появившееся в конце 2002 года поколение D3 олицетворило новый дизайн Audi – массивная передняя решетка в хромированной окантовке. A8 в этом кузове получило более широкую линейку моторов. Шестилитровый W12 получил дополнительные 30 лошадиных сил и стал выдавать 450 л.с. Аналогичная мощность была у «заряженной» версии S8 с 5,2-литровым V10. Машины первых годов выпуска с W12 стоят от 130 миллионов рублей за аукционную модель с внешними повреждениями.

Третье поколение внешне больше походит на рестайлинг, чем на новую модель. Версия с W12 имеет двигатель объемом 6,3 литра и мощностью 500 л.с. Машина разгоняется до 100 км/ч за 4,7 секунды – впечатляющий результат для «дивана» на колесах.

Но это не самая быстрая модификация. Наиболее динамичной и мощной является S8 со скромным (по сравнению с 6,3 W12) 4,0-литровым V8 мощностью 520 л.с., которой требуется 4,2 секунды для ускорения с 0 до 100 км/ч. В продаже версий с W12 не нашлось.

Audi Q7 V12 TDI

Еще одна модель Audi имеет двигатель с двенадцатью цилиндрами – это внедорожник Q7. Первое поколение выпускалось целых десять лет (2005-2015). С 2008 года на машину начали ставить дизельный шестилитровый двигатель V12. Крутящий момент составляет 1000 Нм, мощность – 500 л.с. Разгон до 100 км/ч занимает 5,5 секунд.

Модификация весьма странная. Обычно «заряженными» делают бензиновые модели, в то время как удел дизелей – экономичность. Но в случае с 6-литровым V12, пусть и работающем на солярке, говорить об экономичности неуместно. Именно в абсурдности двигателя и кроется весь сок этой версии. В Минске продается одна Audi Q7 V12 TDI за 964 миллиона рублей.

Bentley Continental GT

Британское купе, что и говорить, выглядит безупречно – только глянув на него, становится ясно, что когда-то Bentley стоил как хороший коттедж недалеко от Минска. Continental GT появился в 2005 году и экземпляры первых годов выпуска успели сильно подешеветь. Например, автомобиль в тюнинге от компании Mansory стоит 686 миллионов рублей – мелочи по сравнению с новым Bentley. Другой Continental GT оценивается в 1,2 миллиарда рублей.

На модель устанавливают мотор W12, который также можно встретить на Audi A8. Мощность в зависимости от версии составляет 552, 602 (Speed) либо 630 (Supersports) «лошадок». Появившееся в 2011 году второе поколение не сразу отличишь от предшественника – чуть другая форма оптики и другие мелкие различия. Купе получило более экономичный мотор V8 объемом 4,0 литра (500 либо 521 л.с.), а для флагманской версии предлагается все тот же 6-литровый W12.

Volkswagen Phaeton

В 2002 году Volkswagen решил заявить о себе в F-сегменте, представив флагманскую модель Phaeton. Седан конструктивно схож с Audi A8 и Bentley Flying Spur. Машина выпускается в одном кузове уже четырнадцатый год, и сведения о ее судьбе все еще противоречивые: то немцы будут выпускать второе поколение, то нет.

На машину за все время производства устанавливалось много двигателей: начиная трехлитровым дизелем и заканчивая шестилитровым бензиновым W12. Также была интересная версия с 5,0 V10 TDI, который помимо Phaeton можно встретить только на VW Touareg. Но сегодня нас интересует только модель с двенадцатью цилиндрами – она имеет тот же двигатель мощностью 450 л.с., что Audi A8 (D3). Модификация с W12 стоит 193 миллиона рублей.

Предполагаемый облик нового Volkswagen Phaeton

Покупка подержанной машины с V/W12 выглядит опрометчивым поступком. Расход топлива у таких моделей обычно большой, обслуживание дорогое, а версии поскромнее с V8 и V6 либо рядными «шестерками» будут дешевле и гораздо ликвиднее. Если гнаться за характеристиками, то, безусловно, модификации с двенадцатью цилиндрами лучшие. Но стоят ли выигранные полсекунды со светофора сопутствующих проблем в виде непомерного аппетита и высокой стоимости обслуживания – вопрос совсем иной.

Флагманские модификации на то и флагманские, что их покупают скорее из-за шильдика V12 и желания потешить свое самолюбие, нежели ради реализации всего потенциала мощнейших двигателей. Первый покупатель вполне может и не задумываться, сколько стоит BMW 760Li и не лучше ли сэкономить, купив 750Li – его наверняка заботят цифры с большим количеством нолей. А вот спустя семь-десять лет топовые версии, побывав у двух-трех владельцев и подешевев раз эдак в десять, оказываются в незавидном положении: их крайне сложно продать, потому что теперешняя аудитория очень даже смотрит как на цену и машины, так и просчитывает стоимость обслуживания. С другой стороны, если финансы позволяют, почему бы не попробовать S600 либо A8 W12 – живем ведь один раз.

led at 60° or 180° from each other, has even firing with power pulses delivered twice as often per revolution as, and is smoother than a straight-6 because there is always positive net torque output, as with an engine with 7 or more cylinders. This allows for great refinement in a luxury car; in a racing car, the rotating parts can be made much lighter and thus more responsive, since there is no need to use counterweights on the crankshaft as is needed in a 90° V8 and less need for the inertial mass in a flywheel to smooth out the power delivery. In a large, heavy-duty engine, a V12 can run slower than smaller engines, prolonging engine life.

Aviation[]

V12 engines were first seen in aircraft. By the end of World War I, the V12 configuration was a fairly popular one in the newest and largest fighters and bombers; V12 engines were produced by companies such as Renault and Sunbeam. Many Zeppelins had V12 engines, from German manufacturers Maybach and Daimler. Various US companies produced the Liberty L-12; the Curtiss NC Flying boats, such as the first aircraft to make a transatlantic flight, the NC-4, had a set of four V12 engines.

A number of World War II fighters and bombers used V12 engines such as the Rolls-Royce Merlin, the Klimov VK-107 or the Allison V-1710 on the Allied side, or the Daimler-Benz DB 600 on the German side, these engines were generating about 1,000 horsepower (0.75 MW) at the beginning of the War and about 1,500 horsepower (1.12 MW) at their ultimate evolution stage. The German DB 605D engine even reached 2000 hp (1.50 MW) with methanol-water injection. Their use disappeared quickly after the advent of the jet engine.

V12 road cars[]

In automobiles, V12 engines have never been common due to their complexity and cost. They are used almost exclusively in expensive sports cars and luxury cars and are sought after for their power and relatively vibration-free operation.

Prior to World War II, twelve-cylinder engines were found in many luxury models, including cars from Cadillac, Packard, Lincoln, Franklin, Rolls-Royce, and Hispano-Suiza. Packard’s 1912 «Double Six» is widely regarded as the first production V12 engine.

Postwar, the type lost favor in the United States, where the V8 engine became ubiquitous. Italian sports cars from such makers as Ferrari and Lamborghini used the V12 almost exclusively on their highest-performance vehicles, while Jaguar developed a V12 that was put into production in 1971 and lasted until 1997, the first modern marque to use the engine in a four-door sedan/saloon. Ferrari’s newest V12 (used in the 599) is based on the Enzo Ferrari’s engine. From 1973-1996, Ferrari also offered a flat 12 engine that was essentially a 180° V12.

German manufacturers Mercedes-Benz and BMW both introduced V12 designs in model year 1992 and 1988, respectively. The BMW-designed V12 also appears in Rolls-Royce cars, while the Mercedes engine is also seen in Maybach cars. Aston Martin introduced a (Cosworth) V12 model in 2000, while Cadillac has contemplated re-introducing the V12 after 60 years with a version of their Cadillac Northstar Engine.

In 1997, Toyota equipped their Century Limousine with a 5.0 L DOHC V-12 (model # 1GZ-FE), making it the first and only Japanese front-engine, rear-wheel drive production car equipped with a V12.

TVR made and tested a 7.7 L V12 called the Speed Twelve, reportedly making 800+ BHP naturally aspirated, but the project was scrapped after the car it was designed for was deemed too powerful for practical use.

Heavy trucks[]

Tatra uses a 17.6 L air-cooled turbo diesel V12 engine in many of their trucks, for instance the Tatra T813 and Tatra T815. Some trucks have been fitted with twin V12s.

GMC produced a large gasoline-burning V12 from 1960 to 1965 for trucks, the «Twin-Six»; it was basically GMC’s large-capacity truck 351 V6, doubled, with four rocker covers and four exhaust manifolds. 56 major parts are interchangeable between the Twin-Six and all other GMC V-6 engines to provide greater parts availability and standardization Its engine displacement was 702 in³ (11.5 L), and while power was not too impressive at 250 SAE net horsepower (190 kW), torque was 585 lbf·ft (793 N·m). It was possibly the last gasoline engine used in heavy trucks in the United States.

Auto racing[]

V12 engines used to be common in Formula One and endurance racing. Between 1965 and 1980, Ferrari, Weslake, Honda, BRM, Maserati, Matra, Alfa-Romeo, Lamborghini and Tecno used 12-cylinder engines in Formula One, either V12 or Flat-12, but the Ford (Cosworth) V8 had a slightly better power-to-weight ratio and less fuel consumption, thus it was more successful despite being less powerful than the best V12s. During the same era, V12 engines were superior to V8s in endurance racing, reduced vibrations giving better reliability. In the 1990s, Renault V10 engines proved their superiority against the Ferrari and Honda V12s and the Ford V8. The last V12 engine in Formula One, was the Ferrari 044, in the Ferrari cars driven by Jean Alesi and Gerhard Berger in 1995.

At the Paris motor show 2006 Peugeot presented a new racing car, as well as a luxury saloon concept car, both called 908 and fitted with a V12 Diesel engine producing around or even surpassing 700 DIN HP. This car will take part in the 24 Hours of Le Mans 2007 race.

Large diesel engines[]

V12 is a common configuration for large diesel engines; most are available with differing numbers of cylinders in V configuration to offer a range of power ratings. Many diesel locomotives have V12 engines.

Mercedes (MTU) manufacture a line of V12 diesel engines for marine use. These engines commonly power craft up to about 100 tonnes in pairwise configurations and range in power from about 1 to 4 MW.

Двигатель V12 — это V-образный двенадцатицилиндровый двиагатель. Как уже логически становится понятно, это очень мощный мотор большого объема, который ставится на спортивные и просто мощные автомобили. К примеру, Mercedes SL 65 AMG имеет мотор V12 с двумя турбонаддувами (мощность 630 сил). Также суперкар Ferrari F12berlinetta имеет мотор V12 6,3 мощностью 730 коней, Aston Martin Vantage V12 S (573 л.с 620 Hm)
