A V6 engine is a V engine with six cylinders mounted on the crankcase in two banks of three cylinders, usually set at either a right angle or an acute angle to each other, with all six pistons driving a common crankshaft. A V engine is a common configuration for an Internal combustion engine. A cylinder is the central working part of a Reciprocating engine, the space in which a Piston travels For the GI Joe character see List of GI Joe ARAH characters. For the Transformers characters see Crankcase (Transformers. A piston is a component of Reciprocating engines Pumps and Gas compressors It is located in a cylinder and is made gas-tight by Piston The crankshaft, sometimes casually abbreviated to crank, is the part of an Engine which translates reciprocating Linear It is the second most common engine configuration in modern cars after the inline four. The straight-4 or inline-4 engine (often abbreviated I4 or L4) is a four cylinder Internal combustion engine with all four cylinders 
The V6 is one of the most compact engine configurations, shorter than the straight 4 and in many designs narrower than the V8 engine, and is well suited to the popular front-wheel drive layout. The straight-4 or inline-4 engine (often abbreviated I4 or L4) is a four cylinder Internal combustion engine with all four cylinders A V8 engine is a V engine with eight cylinders mounted on the Crankcase in two banks of four cylinders in most cases set at a right angle to each other Front-wheel drive (or FF layout) is a form of engine / transmission layout used in Motor vehicles where the engine drives the front Wheels It is becoming more common as the space allowed for engines in modern cars is reduced at the same time as power requirements increase, and has largely replaced the inline-6, which is too long to fit in many modern engine compartments. The straight-6 or inline-6 engine (often abbreviated I6 or L6) is a six cylinder Internal combustion engine with all six cylinders Although it is more complicated and not as smooth as the inline 6, the V6 is more compact, more rigid, and less prone to torsional vibrations in the crankshaft. The V6 engine has become widely adopted for medium-sized cars with engine displacements between 2. 4 and 3. 2 litres (146-195 CID), often as an optional engine where a straight-4 is standard, or as an economy engine where a V8 is a higher-cost option. A cubic inch (plural cubic inches) is a non- SI unit of Volume, equal to the volume of a Cube with sides of one Inch. 
The first V6 was introduced by Lancia in 1950 with the Lancia Aurelia. Lancia Automobiles SpA is an Italian Automobile manufacturer founded in 1906 by Vincenzo Lancia and which became part of the Fiat Group in The Lancia Aurelia is considered by many to be the first true Gran Turismo Automobile. Other manufacturers took note and soon other V6 engines were in use. In 1959, GM introduced a heavy duty 305 cubic inch (5 L) 60-degree V6 for use in their pickup trucks and Suburbans, an engine design that was later enlarged to 478 cubic inches (7.

The design really took off after the 1962 introduction of the Buick Special, which offered a 90 degree V6 with uneven firing intervals that shared some parts commonality with a small Buick V8 of the period. The Buick Special was an Automobile produced by the Buick Motor Division of General Motors, Flint Michigan ( USA) A V8 engine is a V engine with eight cylinders mounted on the Crankcase in two banks of four cylinders in most cases set at a right angle to each other Though the Buick Special met consumer resistance due to its excessive vibration, it was the first instance of a mass-produced V6 engine designed specifically for passenger automobiles. The Buick Special was an Automobile produced by the Buick Motor Division of General Motors, Flint Michigan ( USA) In 1983 Nissan produced Japan's first V6 engine with the VG series. The VG engine family consists of V6 Piston engines designed and produced by Nissan for several vehicles in the Nissan lineup
Modern V6 engines commonly range in displacement from 2. Engine displacement is defined as the total Volume of air/fuel mixture an Engine can draw in during one complete engine cycle it is normally stated in Cubic 5 L to 4. 3 L (150-262 CID), though larger and smaller examples have been produced.

Due to the odd number of cylinders in each bank, V6 designs are inherently unbalanced and can benefit from some auxiliary counterbalancing. In Piston engine engineering a balance A V6 is basically two straight-3 engines running on the same crankshaft, and since the straight-3 suffers from a primary dynamic imbalance which causes an end-to-end rocking motion, the V6 also suffers from the same problem unless steps are taken to mitigate it. A straight-3 or inline-3 is an Internal combustion engine with three cylinders arranged in a straight line side by side Engine balance is the design construction and tuning of an Engine to run smoothly 
Unlike a 90° V8 with crossplane crankshaft, a V6 cannot be laid out so that the vibrations from the two banks completely cancel each other. A V8 engine is a V engine with eight cylinders mounted on the Crankcase in two banks of four cylinders in most cases set at a right angle to each other The crossplane or cross-plane is a Crankshaft design for V8 engines with a 90° angle between the cylinder banks This makes designing a smooth engine a much more complicated affair. When Lancia pioneered the V6 in 1950, they used a 60° angle between the cylinder banks and a six-throw crankshaft to achieve equally spaced firing intervals of 120°. Lancia Automobiles SpA is an Italian Automobile manufacturer founded in 1906 by Vincenzo Lancia and which became part of the Fiat Group in This still has some balance and secondary vibration problems. When Buick designed a 90° V6 based on their 90° V8, they initially used a simpler three-throw crankshaft laid out in the same manner as the V8 with pairs of connecting rods sharing the same crankpin, which resulted in firing intervals alternating between 90° and 150°. This produced a rough-running design which was unacceptable to many customers. Later, Buick and other manufacturers refined the design by using a split-pin crankshaft which achieved a regular 120° firing interval by staggering adjacent crankpins by 15° in opposite directions to eliminate the uneven firing and make the engine reasonably smooth.  Some manufacturers such as Mercedes Benz have taken the 90° design a step further by adding a balancing shaft to offset the primary vibrations and produce an almost fully balanced engine. Mercedes-Benz is a German manufacturer of luxury Automobiles Buses coaches and Trucks It is currently a division of the
Some designers have reverted to a 60° angle between cylinder banks, which produces a more compact engine, but have used three-throw crankshafts with flying arms between the crankpins of each throw to achieve even 120° angles between firing intervals. This has the additional advantage that the flying arms can be weighted for balancing purposes.  This still leaves an unbalanced primary couple, which is offset by counterweights on the crankshaft and flywheel to leave a small secondary couple, which can be absorbed by carefully designed engine mounts. 
Six-cylinder designs are also more suitable for larger displacement engines than four-cylinder ones because power strokes of pistons overlap. In a four-cylinder engine, only one piston is on a power stroke at any given time. Each piston comes to a complete stop and reverses direction before the next one starts its power stroke, which results in a gap between power strokes and noticeable vibrations. In a six-cylinder engine (other than odd-firing V6s), the next piston starts its power stroke 60° before the previous one finishes, which results in smoother delivery of power to the flywheel. In addition, because inertial forces are proportional to the cube of the piston mass and the square of the piston speed, high-speed six-cylinder engines will suffer less stress and vibration than four-cylinder ones of equal displacement. 
Comparing engines on the dynamometer, a typical even-fire V6 shows instantaneous torque peaks of 150% above mean torque and valleys of 125% below mean torque, with a small amount of negative torque (engine torque reversals) between power strokes. For the dynamometer used in railroading see Dynamometer car. A dynamometer or "dyno" for short is a machine used to measure On the other hand, a typical four-cylinder engine' shows peaks of nearly 300% above mean torque and valleys of 200% below mean torque, with 100% negative torque being delivered between strokes. In contrast, a V8 engine shows peaks of less than 100% above and valleys of less than 100% below mean torque, and torque never goes negative. The even-fire V6 thus ranks between the four and the V8, but closer to the V8, in smoothness of power delivery. An odd-fire V6, on the other hand, shows highly irregular torque variations of 200% above and 175% below mean torque, which is significantly worse than an even-fire V6, and in addition the power delivery shows large harmonic vibrations that have been known to destroy the dynamometer. 
The most efficient cylinder bank angle for a V6 is 60 degrees, which design is very compact and tends to minimize vibrations. While they are not as well balanced as inline-6 and flat-6 engines, modern techniques for designing and mounting engines have largely disguised their vibrations. The straight-6 or inline-6 engine (often abbreviated I6 or L6) is a six cylinder Internal combustion engine with all six cylinders flat-6 or horizontally-opposed-6 is a Flat engine with six Cylinders arranged horizontally in two banks of three cylinders on each side of a central Unlike most other angles, 60 degree V6 engines can be made acceptably smooth without the need for balance shafts. When Lancia pioneered the 60° V6 in 1950, they used a 6-throw crankshaft to give equal firing intervals of 120°. Lancia Automobiles SpA is an Italian Automobile manufacturer founded in 1906 by Vincenzo Lancia and which became part of the Fiat Group in However, more modern designs often use a 3-throw crankshaft with what are termed flying arms between the crankpins, which not only give the required 120° separation but also can be used for balancing purposes. Combined with a pair of heavy counterweights on the crankshaft ends, these can eliminate all but a modest secondary imbalance which can easily be damped out by the engine mounts. 
This configuration is a good fit in cars which are too big to be powered by four-cylinder engines, but for which compactness and low cost are important. The most common 60° V6s were built by General Motors (the heavy duty commercial models, as well as a design used in many GM front wheel drive cars) and Ford European subsidiaries (Essex V6, Cologne V6 and the more recent Duratec V6). General Motors Corporation ( GM) ( is a multinational automobile manufacturer founded in 1908 and headquartered in the United States. Ford Motor Company is an American Multinational corporation and the world's fourth largest automaker based on Worldwide vehicle sales, following See also Ford Essex V6 engine (Canadian The Ford Essex V6 engine was a 60° V6 engine built between 1967 and 1988 by the Ford The original Ford Cologne V6, also known as the Ford Taunus V6, 640L was a 60° Cast iron block V6 engine built by the Ford Motor Company The Duratec is a range of four, six and twelve -cylinder Gasoline engines used in Ford cars Other 60° V6 engines are the Chrysler 3. 3 V6 Engine, Nissan VQ engine and the Alfa Romeo V6 engine. The VQ engine is a 20 L to 40 L V6 Piston engine from Nissan. Alfa Romeo' s in-house V6 engine design made its initial début in 1979 in the Alfa 6, later attaining fame under the hood of the Alfa Romeo 164.
90-degree V6 engines are also produced, usually so they can use the same production-line tooling set up to produce V8 engines (which normally have a 90-degree V angle). A V8 engine is a V engine with eight cylinders mounted on the Crankcase in two banks of four cylinders in most cases set at a right angle to each other Although it is relatively easy to derive a 90-degree V6 from an existing V8 design by simply cutting two cylinders off the engine, this tends to make it wider and more vibration-prone than a 60-degree V6. The design was first used by Buick when it introduced its 198 CID Fireball V6 as the standard engine in the 1962 Special. Buick (ˈbjuːɪk is a Marque of automobile sold in the United States, Canada, China, Taiwan, Qatar, and The Buick V6, initially marketed as Fireball at its introduction in 1962 is a large V6 engine used by General Motors. The Buick Special was an Automobile produced by the Buick Motor Division of General Motors, Flint Michigan ( USA) Other examples include the Maserati V6 used in the Citroën SM, the PRV V6, Chevrolet's 4.3 L Vortec 4300 and Chrysler's 3.9 L Magnum V6 and 3.7 L PowerTech V6. Maserati is an Italian manufacturer of racing cars and Sports cars established on December 1, 1914, in Bologna. The Citroën SM was a high performance Coupé produced by the French manufacturer Citroën between 1970 and 1975 The PRV engine is an Automobile petrol V6 Engine that was developed jointly by Peugeot, Renault Chevrolet (ˌʃɛvroʊˈleɪ - French origin (also known as Chevy) is a Brand of Automobile, produced by General Motors (GM I4 2200 The Vortec 2200 (RPO codes L43 and LN2) is a OHV Straight-4 Truck engine Chrysler LLC is an American Automobile manufacturer that has been producing Automobiles since 1925 The LA engine ( Light A engine was an evolution of the Small-block Plymouth polyspheric-head A engine The PowerTech was a new engine family for Chrysler, and was not based on the Chrysler A engine as existing Chrysler V8s were The Buick V6 was notable because it introduced the concept of uneven firing, as a result of using the 90 degree V8 cylinder angle without adjusting the crankshaft design for the V6 configuration. These engines were often referred to by mechanics as "shakers," due to the tendency of the engine to bounce around at idle speed. More modern 90-degree V6 engine designs avoid these vibration problems by using crankshafts with offset split crankpins to make the firing intervals even, and often add balancing shafts to eliminate the other vibration problems. An example is the 90-degree Mercedes-Benz V6 which, although designed to be built on the same assembly lines as the V8, uses split crankpins, a counter-rotating balancing shaft, and careful acoustic design to make it as smooth and quiet as the inline-6 it replaced.
120 degrees might be described as the natural angle for a V6 since the cylinders fire every 120 degrees of crankshaft rotation. Unlike the 60 degree or 90 degree configuration, it allows pairs of pistons to share crank pins in a three-throw crankshaft without requiring flying arms or split crankpins to be even-firing. However, it has few other advantages in a road car. The 120° layout produces an engine which is too wide for most automobile engine compartments, and it suffers from a primary dynamic imbalance which requires a balance shaft to offset. In Piston engine engineering a balance It is more often used in racing cars where the car is designed around the engine rather than vice-versa, and vibration is not as important. On the other hand, the flat-6 boxer engine is only moderately wider, and unlike the V6 is a fully-balanced configuration with no vibration problems, so it is more commonly used in aircraft and in sports/luxury cars where space is not a constraint and smoothness is important. flat-6 or horizontally-opposed-6 is a Flat engine with six Cylinders arranged horizontally in two banks of three cylinders on each side of a central
Ferrari introduced a very successful 120° V6 racing engine in 1961. Ferrari SpA is an Italian Sports car manufacturer based in Maranello, Italy The Ferrari Dino 156 engine was shorter and lighter than the 65° Ferrari V6 engines that preceded it, and the simplicity and low center of gravity of the engine was an advantage in racing. Dino was a brand for mid-engined rear-drive Sports cars produced by Ferrari from 1968 to 1976 It won a large number of Formula 1 races between 1961 and 1964. However, Enzo Ferrari had a personal dislike of the 120° V6 layout, preferring a 65° angle, and after that time it was replaced by other engines. Enzo Anselmo "the Commendatore" Ferrari ( February 20, 1898 &ndash August 14, 1988) was an Italian car driver and entrepreneur 
Bombardier has designed 120° V220/V300T V6 engines for use in light aircraft. Bombardier Inc (bɔ̃baʁdje is a Canadian conglomerate, founded by Joseph-Armand Bombardier as L'Auto-Neige Bombardier Limitée in 1942 The ignition sequence is symmetrical, with each cylinder firing 120 degree after the previous cylinder resulting in smooth power delivery. A balance shaft on the bottom of the engine offsets the primary dynamic imbalance intrinsic in any V6 layout. The straight, pin-type crankshaft journals in the 120° V-6 layout allow a shorter and stiffer crankshaft than competing flat-6 engines, while water cooling results in better temperature control than air cooling. These engines have the additional advantage that they can run on automotive gasoline rather than avgas, but have been produced only in limited quantities to date. Avgas is a high-octane Aviation fuel used for Aircraft and Racing cars Avgas is a Portmanteau for aviation gasoline
Narrower angle V6 engines are very compact but can suffer from severe vibration problems unless very carefully designed. Notable V6 bank angles include:
Many older V6 engines were based on V8 engine designs, without altering the V angle or using a more sophisticated crankshaft to even out the firing interval. A V8 engine is a V engine with eight cylinders mounted on the Crankcase in two banks of four cylinders in most cases set at a right angle to each other One characteristic of these engines was a notorious odd-firing behavior.
Purpose-built V6 engines use one crankpin per cylinder for an even 120° ignition pattern. In contrast, most V8 engines share a common crankpin between opposite cylinders in each bank. That is, the crankshaft has just four pins for eight cylinders, and a cylinder fires every 90° for smooth operation. The crankshaft, sometimes casually abbreviated to crank, is the part of an Engine which translates reciprocating Linear
V6 engines derived from V8 engines often have three shared crankpins arranged at 120° from each other, similar to an inline 3-cylinder, with two pistons per crankpin. A straight-3 or inline-3 is an Internal combustion engine with three cylinders arranged in a straight line side by side If the cylinder banks are arranged at 90° (as they commonly are in V8-derived V6s), this leads to a firing pattern with groups of two cylinders separated by 90° of rotation, and groups separated by 150° of rotation.
An example is the Buick 231 odd-fire, which has a firing order 1-6-5-4-3-2. The Buick V6, initially marketed as Fireball at its introduction in 1962 is a large V6 engine used by General Motors. The firing order is the sequence of power delivery of each cylinder in a multi-cylinder Reciprocating engine. As the crankshaft is rotated through the 720° required for all cylinders to fire, the following events occur on 30° boundaries:
Nissan uses the firing order 1-2-3-4-5-6 in some of the V6 engines they make.
In 1977, Buick introduced a new "split-pin crankshaft" in the 231. Buick (ˈbjuːɪk is a Marque of automobile sold in the United States, Canada, China, Taiwan, Qatar, and The Buick V6, initially marketed as Fireball at its introduction in 1962 is a large V6 engine used by General Motors. Using a crankpin that is 'split' and offset by 30° of rotation resulted in smooth, even firing every 120°. However, in 1978 Chevrolet introduced a 90° 200/229 V6, which had a compromise 'semi-even firing' design using a crankpin that was offset by only 18°. This resulted in cylinders firing at 108° and 132°, which had the advantage of reducing vibrations to a more acceptable level and did not require strengthening the crankshaft. In 1985 Chevrolet's 4. 3 (later the Vortec 4300) changed it to a true even-firing V6 with a 30° offset, requiring larger crank journals to make them adequately strong.
In 1986 the similarly-designed 90° PRV engine adopted the same 30° crankshaft offset design to even out its firing. The PRV engine is an Automobile petrol V6 Engine that was developed jointly by Peugeot, Renault Most recent 90° V6 designs use split crankpins to even out the firing intervals. Such a 'split' crankpin is weaker than a straight one, but modern metallurgical techniques can produce a crankshaft that is adequately strong. Metallurgy is a domain of Materials science that studies the physical and chemical behavior of metallic elements, their intermetallic compounds, and their
The V6 engine was introduced into racing by Lancia in the early '50s. Lancia Automobiles SpA is an Italian Automobile manufacturer founded in 1906 by Vincenzo Lancia and which became part of the Fiat Group in After good results with privately entered Aurelia saloons Lancia set a works competition department in 1951. The Lancia Aurelia is considered by many to be the first true Gran Turismo Automobile. Four B20 Coupes were entered in the '51 Mille Miglia and the one driven by Giovanni Bracco and Umberto Maglioli caused quite a stir by finishing second overally after the 4. The Mille Miglia (Thousand Miles - pronounced 'miʎʎa was an open-road endurance race which took place in Italy twenty-four times from 1927 to 1957 (thirteen Giovanni Bracco ( June 6 1908 at Biella - August 6 1968 same place was an Italian racing car driver remembered for losing control Umberto Maglioli (born in Bioglio, Vercelli, June 5, 1928 &ndash died in Monza, February 7, 1999) was a 1-litre Ferrari driven by Villoresi and Cassani, a car which three times more power than the Lancia. After that encouraging start Lancia decided to carry on with the endurance racing program, first with specially prepared Aurelias (called Da Corsa) and then with specially built prototypes. A D24 with a 3102 cc V6 making 230 brake horsepower (170 kW) won the 1953 Carrera Panamericana with Juan Manuel Fangio at the wheel. The Carrera Panamericana was a Sports car racing event on open roads in Mexico, similar to the Mille Miglia and Targa Florio in Italy Juan Manuel Fangio ( Balcarce, June 24, 1911 - Buenos Aires, July 17, 1995) nicknamed "El Chueco" ("knock-kneed"
After that came the Ferrari Dino V6. Ferrari SpA is an Italian Sports car manufacturer based in Maranello, Italy Alfredo Ferrari (nicknamed Dino), the only legitimate son of Enzo Ferrari, suggested to him the development of a 1. Alfredo Ferrari (January 1932 &ndash June 30, 1956) nicknamed Alfredino or Dino, was the only legitimate son of Enzo Ferrari. Enzo Anselmo "the Commendatore" Ferrari ( February 20, 1898 &ndash August 14, 1988) was an Italian car driver and entrepreneur 5 L DOHC V6 engine for Formula Two at the end of 1955. Overhead camshaft, commonly abbreviated to OHC, Valvetrain configurations place the engine Camshaft within the Cylinder heads above the Formula Two, abbreviated to F2, was a type of Formula racing. Soon afterwards, Alfredo fell ill, suffering from muscular dystrophy. Muscular dystrophy (MD refers to a group of genetic, Hereditary Muscle diseases that cause progressive muscle weakness While in hospital, he discussed technical details with the engineer Vittorio Jano. Vittorio Jano (János Viktor 22 April 1891 &ndash 13 March 1965) was an Italian Automobile designer of Hungarian Dino would never see the engine; he died on June 30, 1956 at the age of 24.
The Dino V6 underwent several evolutions, including an increased engine displacement to 2417 cc, for use in the Ferrari 246 Formula One car in 1958. Engine displacement is defined as the total Volume of air/fuel mixture an Engine can draw in during one complete engine cycle it is normally stated in Cubic The Ferrari 246 F1 was a Ferrari Racing car built for the Formula One World Championship of 1958. 
The use of a wide 120° bank angle is appealing for racing engine designers as it permits a low center of gravity. This design is even considered superior to the flat-6 in that it leaves more space under the engine for exhaust pipes; thus the crankshaft can be placed lower in the car. flat-6 or horizontally-opposed-6 is a Flat engine with six Cylinders arranged horizontally in two banks of three cylinders on each side of a central The Ferrari 156 built for new Formula One 1. The Ferrari 156 was a Racecar made by Ferrari in 1961 to comply with then-new F1 regulations that lowered engine displacement from 2 5 L regulations used a Dino V6 engine with this configuration. 
The Dino V6 engine saw a new evolution in 1966 when it was adapted to road use and produced by a Ferrari-Fiat joint-venture for the Fiat Dino and Dino 206 GT (this car was made by Ferrari but sold under the brand Dino). This new version was redesigned by Aurelio Lampredi initially as a 65° 2. Aurelio Lampredi ( June 16, 1917 in Livorno - June 1, 1989 in Livorno) was an Italian Automobile and 0 L V6 with an aluminum block but was replaced in 1969 by a 2. 4 L cast-iron block version (the Dino car was renamed the 246GT).
The Fiat Dino and Dino 246GT were phased out in 1974, but 500 engines among the last built were delivered to Lancia, who was like Ferrari already under the control of Fiat. Lancia Automobiles SpA is an Italian Automobile manufacturer founded in 1906 by Vincenzo Lancia and which became part of the Fiat Group in Fiat SpA (an Acronym for Fabbrica Italiana Automobili Torino (Italian Automobile Factory of Turin) is an Italian automobile manufacturer Lancia used them for the Lancia Stratos which would become one of the most successful rally cars of the decade.

Rallying is a form of motor competition that takes place on public or private roads with modified production or specially built road-legal cars
The Alfa Romeo V6 was designed in the 1970s by Giuseppe Busso, the first car to use them being the Alfa Romeo 6. Alfa Romeo' s in-house V6 engine design made its initial début in 1979 in the Alfa 6, later attaining fame under the hood of the Alfa Romeo 164. Giuseppe Busso ( 1913 - January 3, 2006) was an Alfa Romeo and Ferrari technical designer The Alfa Romeo Alfa 6 is an Executive car produced by the Italian automaker Alfa Romeo from 1979 to 1986 The over-square V6, with aluminium alloy block and heads, has seen continuous use in road vehicles, from the Alfetta GTV6 onwards. The 164 introduced a 3. 0L V6, and in 1992, a 3. 0L DOHC 24 valve version. The Alfa 156 introduced a 2. The Alfa Romeo 156 (known internally as the type 932 is a Compact executive car introduced by Italian automaker Alfa Romeo at the 1997 Frankfurt Motor 5 L DOHC 24 valve version in 1997. The engine capacity was later increased to 3. 2L, where it found application in the 156 GTA, 147 GTA and the Alfa GT. Production was discontinued in 2005.
Another influential V6 design was the Renault-Gordini CH1 V6, designed by François Castaing and Jean-Pierre Boudy, and introduced in 1973 in the Alpine-Renault A440. This is about the company for other uses see Renault (disambiguation. Gordini was a French sports car manufacturer The firm was founded by Amédée Gordini nicknamed "Le Sorcier" (The Sorcerer François J Castaing (born 1945 in France) is a 27-year veteran automotive executive with Renault, American Motors, and Chrysler. Alpine is also the name of car models produced by Sunbeam and Chrysler. The CH1 was a 90° cast iron block V6, similar to the mass produced PRV engine in those two respects but otherwise dissimilar. Cast iron usually refers to grey cast iron, but identifies a large group of Ferrous Alloys which solidify with a Eutectic. It has been suggested that marketing purposes made the Renault-Gordini V6 adopt those characteristics of the PRV in the hope of associating the two in the public's mind.
Despite such considerations, this engine won the European 2 L prototype championship in 1974 and several European Formula Two titles. Formula Two, abbreviated to F2, was a type of Formula racing. This engine was further developed in a tubocharged 2 L version that competed in Sports car and finally won the 24 Hours of Le Mans in 1978 with a Renault-Alpine A 442 chassis. The 24 Hours of Le Mans ( 24 Heures du Mans) is a sports car endurance race held annually since near the town of Le Mans, Sarthe,
The capacity of this engine was reduced to 1. 5 L to power the Formula One Renault RS01. Despite frequent breakdowns that resulted in the nickname of the 'Little Yellow Teapot', the 1. 5 L finally saw good results in 1979.
Ferrari followed Renault in the turbo revolution by introducing a turbocharged derivative of the Dino design (a 1. 5 L 120° V6) with the Ferrari 126.  However, the 120° design was not considered optimum for the wing cars of the era and later engines used V angles of 90° or less. For another similarly named effect relating to aircraft see Ground effect in aircraft.
Both Renault and Ferrari failed in their attempt to win the Drivers' Championship with V6 Turbo engines. The first turbocharged engine to win the championship was the Straight-4 BMW. The straight-4 or inline-4 engine (often abbreviated I4 or L4) is a four cylinder Internal combustion engine with all four cylinders ( BMW) (Bavarian Motor Works is an independent German automobile manufacturer founded in 1916
They were followed by a new generation of Formula One engines, the most successful of these being the TAG V6 (designed by Porsche) and the Honda V6. Porsche SE or Porsche ( German, ˈpɔɹʃə is a German manufacturer of automobiles which is majority-owned by the Porsche and Piëch () is a Multinational corporation, engine Manufacturer and engineering corporation headquartered in Japan. This new generation of engines were characterized by odd V angles (around 80°). The choice of these angles was mainly driven by aerodynamic consideration. Despite their unbalanced designs these engines were both quickly reliable and competitive; this is generally viewed as a consequence of the quick progress of CAD techniques in that era.
An often neglected aspect to the history of the Chrysler 3. 3L V6 engine is its brief use in racing with the Shelby Dodge Can Am circuit.
In 1989 Shelby tried to bring back the Can-Am series, using the 3. 3L V6 (not yet offered to the general public) as the powerplant in a special racing configuration making 255 horsepower (190 kW). This was the same year that the Viper concept was showed to the public.
Originally the plan was to produce two versions of this race car, a 255 horsepower (190 kW) version and a ~500 horsepower (370 kW) model, the 255 horsepower (190 kW) version being the entry circuit. The cars were designed to be a cheap way for more people to enter auto racing. Since all the cars were identical, the winners were to be the people with the best talent, not the team with the biggest pockets. The engines had Shelby seals on them and could only be repaired by Shelby's shop, ensuring that all the engines are mechanically identical.
Only 100 of these 3. 3s were ever built. Of these 100, 76 were put into Shelby Can-Am cars (the only 76 that were ever sold). No significant amount of spare parts were produced, and the unsold engines were used for parts/spares. The Shelby specific parts, such as the upper intake manifold, were never made available to the general public.
According to a small article in the USA Today (in 1989), these cars were making 250 horsepower (190 kW) [stock versions introduced in 1990 produced 150 hp) and hitting 160 mph (260 km/h) on the track.
Now as to how the engine is similar (and different) to a stock Mopar 3. 3:
The engine itself was not that far from a standard-production 3. 3. The Shelby engine is only making about 50 horsepower (37 kW) more than the newest 3. 3 factory engines from Chrysler.
