Italy
Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Austria, San Marino, Italy covers an area of 301,338 km2 and has a largely temperate seasonal climate and Mediterranean climate. Due to its shape, it is referred to in Italy as lo Stivale. With 61 million inhabitants, it is the fourth most populous EU member state, the Italic tribe known as the Latins formed the Roman Kingdom, which eventually became a republic that conquered and assimilated other nearby civilisations. The legacy of the Roman Empire is widespread and can be observed in the distribution of civilian law, republican governments, Christianity. The Renaissance began in Italy and spread to the rest of Europe, bringing a renewed interest in humanism, exploration, Italian culture flourished at this time, producing famous scholars and polymaths such as Leonardo da Vinci, Galileo and Machiavelli. The weakened sovereigns soon fell victim to conquest by European powers such as France and Austria.
Despite being one of the victors in World War I, Italy entered a period of economic crisis and social turmoil. The subsequent participation in World War II on the Axis side ended in defeat, economic destruction. Today, Italy has the third largest economy in the Eurozone and it has a very high level of human development and is ranked sixth in the world for life expectancy. The country plays a prominent role in regional and global economic, military and diplomatic affairs, as a reflection of its cultural wealth, Italy is home to 51 World Heritage Sites, the most in the world, and is the fifth most visited country. The assumptions on the etymology of the name Italia are very numerous, according to one of the more common explanations, the term Italia, from Latin, was borrowed through Greek from the Oscan Víteliú, meaning land of young cattle. The bull was a symbol of the southern Italic tribes and was often depicted goring the Roman wolf as a defiant symbol of free Italy during the Social War. Greek historian Dionysius of Halicarnassus states this account together with the legend that Italy was named after Italus, mentioned by Aristotle and Thucydides.
The name Italia originally applied only to a part of what is now Southern Italy – according to Antiochus of Syracuse, but by his time Oenotria and Italy had become synonymous, and the name applied to most of Lucania as well. The Greeks gradually came to apply the name Italia to a larger region, excavations throughout Italy revealed a Neanderthal presence dating back to the Palaeolithic period, some 200,000 years ago, modern Humans arrived about 40,000 years ago. Other ancient Italian peoples of undetermined language families but of possible origins include the Rhaetian people and Cammuni. Also the Phoenicians established colonies on the coasts of Sardinia and Sicily, the Roman legacy has deeply influenced the Western civilisation, shaping most of the modern world
Transmission (mechanics)
A transmission is a machine in a power transmission system, which provides controlled application of the power. Often the term refers simply to the gearbox that uses gears and gear trains to provide speed. In British English, the term refers to the whole drivetrain, including clutch, prop shaft, differential. In American English, the term more specifically to the gearbox alone. The most common use is in vehicles, where the transmission adapts the output of the internal combustion engine to the drive wheels. Such engines need to operate at a high rotational speed, which is inappropriate for starting, stopping. The transmission reduces the engine speed to the slower wheel speed. Transmissions are used on bicycles, fixed machines. Often, a transmission has multiple gear ratios with the ability to switch between them as speed varies and this switching may be done manually or automatically. Directional control may be provided, single-ratio transmissions exist, which simply change the speed and torque of motor output.
The output of the transmission is transmitted via the driveshaft to one or more differentials, while a differential may provide gear reduction, its primary purpose is to permit the wheels at either end of an axle to rotate at different speeds as it changes the direction of rotation. Conventional gear/belt transmissions are not the mechanism for speed/torque adaptation. Alternative mechanisms include torque converters and power transformation, automatic transmissions use a valve body to shift gears using fluid pressures in conjunction with an ecm. Early transmissions included the right-angle drives and other gearing in windmills, horse-powered devices, and steam engines, in support of pumping, most modern gearboxes are used to increase torque while reducing the speed of a prime mover output shaft. This means that the shaft of a gearbox rotates at a slower rate than the input shaft. A gearbox can be set up to do the opposite and provide an increase in speed with a reduction of torque. Some of the simplest gearboxes merely change the rotational direction of power transmission.
Many typical automobile transmissions include the ability to select one of several gear ratios, in this case, most of the gear ratios are used to slow down the output speed of the engine and increase torque
Ferrari
Ferrari N. V. is an Italian sports car manufacturer based in Maranello. Founded by Enzo Ferrari in 1939 as Auto Avio Costruzioni, the company built its first car in 1940, however the companys inception as an auto manufacturer is usually recognized in 1947, when the first Ferrari-badged car was completed. Ferrari is the worlds most powerful according to Brand Finance. In May 2012 the 1962 Ferrari 250 GTO became the most expensive car in history, Fiat S. p. A. acquired 50 percent of Ferrari in 1969 and expanded its stake to 90 percent in 1988. In October 2014 Fiat Chrysler Automobiles announced its intentions to separate Ferrari S. p. A. from FCA, through the remaining steps of the separation, FCAs interest in Ferraris business was distributed to shareholders of FCA, with 10 percent continuing to be owned by Piero Ferrari. The spin-off was completed on 3 January 2016, Ferrari road cars are generally seen as a symbol of speed and wealth. Enzo Ferrari was not initially interested in the idea of producing road cars when he formed Scuderia Ferrari in 1929, Scuderia Ferrari literally means Ferrari Stable and is usually used to mean Team Ferrari.
Ferrari bought and fielded Alfa Romeo racing cars for gentlemen drivers, in September 1939 Enzo Ferrari left Alfa Romeo under the provision that he would not use the Ferrari name in association with races or racing cars for at least four years. A few days he founded Auto Avio Costruzioni, headquartered in the facilities of the old Scuderia Ferrari, the new company ostensibly produced machine tools and aircraft accessories. In 1940 Ferrari did in fact produce a race car – the Tipo 815 and it was the first Ferrari car and debuted at the 1940 Mille Miglia, but due to World War II it saw little competition. In 1943 the Ferrari factory moved to Maranello, where it has remained ever since, the factory was bombed by the Allies and subsequently rebuilt including a works for road car production. The first Ferrari-badged car was the 1947125 S, powered by a 1.5 L V12 engine, Enzo Ferrari reluctantly built, the Scuderia Ferrari name was resurrected to denote the factory racing cars and distinguish them from those fielded by customer teams.
In 1960 the company was restructured as a corporation under the name SEFAC S. p. A. Early in 1969, Fiat took a 50 percent stake in Ferrari, new model investment further up in the Ferrari range received a boost. In 1988, Enzo Ferrari oversaw the launch of the Ferrari F40, the last new Ferrari to be launched before his death that year, in 1989 the company was renamed as Ferrari S. p. A. From 2002 to 2004, Ferrari produced the Enzo, their fastest model at the time and it was to be called the F60, continuing on from the F40 and F50, but Ferrari was so pleased with it, they called it the Enzo instead. It was initially offered to loyal and reoccurring customers, each of the 399 made had a tag of $650,000 apiece. On 15 September 2012,964 Ferrari cars (worth over $162 million attended the Ferrari Driving Days event at Silverstone Circuit, on 29 October 2014, the FCA group, resulting from the merger between manufacturers Fiat and Chrysler, announced the split of its luxury brand, Ferrari
Automatic transmission
The number of forward gear ratios is often expressed for manual transmissions as well. The most popular form found in automobiles is the automatic transmission. Similar but larger devices are used for heavy-duty commercial and industrial vehicles. This system uses a coupling in place of a friction clutch. These systems have a set of gear ranges, often with a parking pawl that locks the output shaft of the transmission to keep the vehicle from rolling either forward or backward. Some machines with limited speed ranges or fixed engine speeds, such as forklifts and lawn mowers. Despite superficial similarity to other transmissions, traditional automatic transmissions differ significantly in internal operation and drivers feel from semi-automatics and CVTs. In contrast to conventional automatic transmissions, a CVT uses a belt or other torque transmission scheme to allow a number of gear ratios instead of a fixed number of gear ratios. A semi-automatic retains a clutch like a transmission, but controls the clutch through electrohydraulic means.
The ability to shift gears manually, often via paddle shifters, can be found on certain automated transmissions, semi-automatics, the obvious advantage of an automatic transmission to the driver is the lack of a clutch pedal and manual shift pattern in normal driving. This allows the driver to operate the car with as few as two limbs, allowing amputees and other disabled individuals to drive, the automatic transmission was invented in 1921 by Alfred Horner Munro of Regina, Saskatchewan and patented under Canadian patent CA235757 in 1923. Being a steam engineer, Munro designed his device to use compressed air rather than hydraulic fluid and they were incorporated into GM-built tanks during World War II and, after the war, GM marketed them as being battle-tested. However, a Wall Street Journal article credits ZF Friedrichshafen with the invention, zFs origins were in manufacturing gears for airship engines beginning in 1915, the company was founded by Ferdinand von Zeppelin. Modern automatic transmissions can trace their origins to an early horseless carriage gearbox that was developed in 1904 by the Sturtevant brothers of Boston and this unit had two forward speeds, the ratio change being brought about by flyweights that were driven by the engine.
At higher engine speeds, high gear was engaged, as the vehicle slowed down and engine RPM decreased, the gearbox would shift back to low. Unfortunately, the metallurgy of the time wasnt up to the task, and owing to the abruptness of the gear change, the next significant phase in the automatic transmissions development occurred in 1908 with the introduction of Henry Fords remarkable Model T. The pedals actuated the transmissions friction elements to select the desired gear, in 1934, both REO and General Motors developed semi-automatic transmissions that were less difficult to operate than a fully manual unit. These designs, continued to use a clutch to engage the engine with the transmission, parallel to the development in the 1930s of an automatically shifting gearbox was Chryslers work on adapting the fluid coupling to automotive use
Steel
Steel is an alloy of iron and other elements, primarily carbon, that is widely used in construction and other applications because of its high tensile strength and low cost. Steels base metal is iron, which is able to take on two forms, body centered cubic and face centered cubic, depending on its temperature. It is the interaction of those allotropes with the elements, primarily carbon. In the body-centred cubic arrangement, there is an atom in the centre of each cube. Carbon, other elements, and inclusions within iron act as hardening agents that prevent the movement of dislocations that otherwise occur in the lattices of iron atoms. The carbon in steel alloys may contribute up to 2. 1% of its weight. Steels strength compared to pure iron is possible at the expense of irons ductility. With the invention of the Bessemer process in the mid-19th century and this was followed by Siemens-Martin process and Gilchrist-Thomas process that refined the quality of steel. With their introductions, mild steel replaced wrought iron, further refinements in the process, such as basic oxygen steelmaking, largely replaced earlier methods by further lowering the cost of production and increasing the quality of the product.
Today, steel is one of the most common materials in the world and it is a major component in buildings, tools, automobiles, machines and weapons. Modern steel is generally identified by various grades defined by assorted standards organizations, the noun steel originates from the Proto-Germanic adjective stakhlijan, which is related to stakhla. The carbon content of steel is between 0. 002% and 2. 1% by weight for plain iron–carbon alloys and these values vary depending on alloying elements such as manganese, nickel, tungsten, carbon and so on. Basically, steel is an alloy that does not undergo eutectic reaction. In contrast, cast iron does undergo eutectic reaction, too little carbon content leaves iron quite soft and weak. Carbon contents higher than those of steel make an alloy, commonly called pig iron, while iron alloyed with carbon is called carbon steel, alloy steel is steel to which other alloying elements have been intentionally added to modify the characteristics of steel. Common alloying elements include, nickel, molybdenum, titanium, tungsten and niobium.
Additional elements are important in steel, sulfur and traces of oxygen and copper. Alloys with a higher than 2. 1% carbon content, depending on other element content, cast iron is not malleable even when hot, but it can be formed by casting as it has a lower melting point than steel and good castability properties
Fuel injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. All diesel engines use fuel injection by design, petrol engines can use gasoline direct injection, where the fuel is directly delivered into the combustion chamber, or indirect injection where the fuel is mixed with air before the intake stroke. On petrol engines, fuel injection replaced carburetors from the 1980s onward, the functional objectives for fuel injection systems can vary. All share the task of supplying fuel to the combustion process. Carburetors have the potential to atomize fuel better, Fuel injection dispenses with the need for a separate mechanical choke, which on carburetor-equipped vehicles must be adjusted as the engine warms up to normal temperature. Furthermore, on spark ignition engines, fuel injection has the advantage of being able to facilitate stratified combustion which have not been possible with carburetors, Fuel injection generally increases engine fuel efficiency.
With the improved cylinder-to-cylinder fuel distribution of multi-point fuel injection, less fuel is needed for the power output. Exhaust emissions are cleaner because the precise and accurate fuel metering reduces the concentration of toxic combustion byproducts leaving the engine. The more consistent and predictable composition of the exhaust makes emissions control devices such as catalytic converters more effective, herbert Akroyd Stuart developed the first device with a design similar to modern fuel injection, using a jerk pump to meter out fuel oil at high pressure to an injector. This system was used on the engine and was adapted and improved by Bosch. Fuel injection was in commercial use in diesel engines by the mid-1920s. Another early use of direct injection was on the Hesselman engine invented by Swedish engineer Jonas Hesselman in 1925. Hesselman engines use the ultra lean-burn principle, fuel is injected toward the end of the compression stroke and they are often started on gasoline and switched to diesel or kerosene.
Direct fuel injection was used in notable World War II aero-engines such as the Junkers Jumo 210, the Daimler-Benz DB601, the BMW801, German direct injection petrol engines used injection systems developed by Bosch from their diesel injection systems. Later versions of the Rolls-Royce Merlin and Wright R-3350 used single point fuel injection, due to the wartime relationship between Germany and Japan, Mitsubishi had two radial aircraft engines utilizing fuel injection, the Mitsubishi Kinsei and the Mitsubishi Kasei. Alfa Romeo tested one of the first electronic systems in Alfa Romeo 6C2500 with Ala spessa body in 1940 Mille Miglia. The engine had six electrically operated injectors and were fed by a semi-high-pressure circulating fuel pump system, all diesel engines have fuel injected into the combustion chamber. The invention of mechanical injection for gasoline-fueled aviation engines was by the French inventor of the V8 engine configuration, Leon Levavasseur in 1902, the first post-World War I example of direct gasoline injection was on the Hesselman engine invented by Swedish engineer Jonas Hesselman in 1925
V12 engine
By using split crankpins or ignoring minor vibrations, any V angle is possible. The 180° configuration is referred to as a flat-twelve engine or a boxer although it is in reality a 180° V since the pistons can. This is not important in a car if all-out performance is the only goal. Since cost and fuel economy are usually important even in luxury and racing cars and it is often used in marine engines where great power is required, and the hull width is limited, but a longer vessel allows faster hull speed. In twin-propeller boats, two V12 engines can be 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, after World War II, the compact, more powerful, and vibration-free turboprop and turbojet engines replaced the V12 in aircraft applications. The first V-type engine was built in 1889 by Daimler, to a design by Wilhelm Maybach, by 1903 V8 engines were being produced for motor boat racing by the Société Antoinette to designs by Léon Levavasseur, building on experience gained with in-line four-cylinder engines.
In 1904, the Putney Motor Works completed a new V12 marine racing engine—the first V12 engine produced for any purpose, a single camshaft mounted in the central V operated the valves directly. As in many engines, the camshaft could be slid longitudinally to engage a second set of cams. Starting is by pumping a charge into each cylinder and switching on the trembler coils, a sliding camshaft gave direct reversing. The camshaft has fluted webs and main bearings in graduated thickness from the largest at the flywheel end, displacing 1,120 cu in, the engine weighed 950 pounds and developed 150 bhp. Little is known of the achievements in the 40-foot hull for which it was intended. One V12 Dörwald marine engine was still running in a Hong Kong junk in the late-1960s. Two more V12s appeared in the 1909-1910 motor boat racing season, the Lamb Boat & Engine Company of Clinton, Iowa built a 1,559 cu in engine for the companys 32-foot Lamb IV. It weighed in at 2,114 pounds, no weight is known for the massive 3,464 cu in F-head engine built by the Orleans Motor Company.
Output is quoted as nearly 400 bhp, by 1914, when Panhard built two 2,356 cu in engines with four-valve cylinder heads the V12 was well established in motor boat racing. In October 1913, Louis Coatalen, chief engineer of the Sunbeam Motor Car Company entered a V12 powered car in the Brooklands short, the engine displaced 9 L, with bore and stroke of 80 x 150 mm. An aluminum crankcase carried two blocks of three cylinders each along each side, with a 60 degree included angle, the cylinders were of iron, with integral cylinder heads with L-shaped combustion chambers
Hydraulics
Hydraulics is a technology and applied science using engineering and other sciences involving the mechanical properties and use of liquids or fluids. At a very basic level, hydraulics is the version of pneumatics. Fluid mechanics provides the foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In fluid power, hydraulics are used for the generation, hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design and fluid control circuitry, pumps. The principles of hydraulics are in use naturally in the body within the heart. Free surface hydraulics is the branch of hydraulics dealing with surface flow, such as occurring in rivers, lakes, estuaries. Its sub-field open channel flow studies the flow in open channels, the word hydraulics originates from the Greek word ὑδραυλικός which in turn originates from ὕδωρ and αὐλός. Early uses of water power date back to Mesopotamia and ancient Egypt, other early examples of water power include the Qanat system in ancient Persia and the Turpan water system in ancient Central Asia.
The Greeks constructed sophisticated water and hydraulic power systems, an example is the construction by Eupalinos, under a public contract, of a watering channel for Samos, the Tunnel of Eupalinos. An early example of the usage of hydraulic wheel, probably the earliest in Europe, is the Perachora wheel, notable is the construction of the first hydraulic automata by Ctesibius and Hero of Alexandria. Hero describes a number of working machines using hydraulic power, such as the force pump, in ancient China there was Sunshu Ao, Ximen Bao, Du Shi, Zhang Heng, and Ma Jun, while medieval China had Su Song and Shen Kuo. Du Shi employed a waterwheel to power the bellows of a blast furnace producing cast iron, Zhang Heng was the first to employ hydraulics to provide motive power in rotating an armillary sphere for astronomical observation. In ancient Sri Lanka, hydraulics were used in the ancient kingdoms of Anuradhapura. The discovery of the principle of the tower, or valve pit. By the first century AD, several irrigation works had been completed.
The coral on the rock at the site includes cisterns for collecting water. They were among the first to use of the siphon to carry water across valleys. They used lead widely in plumbing systems for domestic and public supply, hydraulic mining was used in the gold-fields of northern Spain, which was conquered by Augustus in 25 BC
Drive shaft
As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be enough to bear the stress, whilst avoiding too much additional weight as that would in turn increase their inertia. The term drive shaft first appeared during the mid 19th century, in Stovers 1861 patent reissue for a planing and matching machine, the term is used to refer to the belt-driven shaft by which the machine is driven. The term is not used in his original patent, another early use of the term occurs in the 1861 patent reissue for the Watkins and Bryson horse-drawn mowing machine. Here, the term refers to the transmitting power from the machines wheels to the gear train that works the cutting mechanism. In the 1890s, the term began to be used in a closer to the modern sense. In 1899, Bukey used the term to describe the shaft transmitting power from the wheel to the machinery by a universal joint in his Horse-Power. In the same year, Clark described his Marine Velocipede using the term to refer to the shaft transmitting power through a universal joint to the propeller shaft.
Crompton used the term to refer to the shaft between the transmission of his steam-powered Motor Vehicle of 1903 and the driven axle, an automobile may use a longitudinal shaft to deliver power from an engine/transmission to the other end of the vehicle before it goes to the wheels. A pair of short drive shafts is commonly used to power from a central differential, transmission. In front-engined, rear-drive vehicles, a drive shaft is required to send power the length of the vehicle. Two forms dominate, The torque tube with a universal joint. This system became known as Système Panhard after the automobile company Panhard et Levassor patented it, most of these vehicles have a clutch and gearbox mounted directly on the engine, with a drive shaft leading to a final drive in the rear axle. When the vehicle is stationary, the drive shaft does not rotate, some vehicles, seeking improved weight balance between front and rear, use a rear-mounted transaxle. This places the clutch and transmission at the rear of the car, in this case the drive shaft rotates continuously with the engine, even when the car is stationary and out of gear. A drive shaft connecting a rear differential to a wheel may be called a half-shaft.
The name derives from the fact that two such shafts are required to one rear axle. Early automobiles often used chain drive or belt drive mechanisms rather than a drive shaft, some used electrical generators and motors to transmit power to the wheels
Ferrari 456
The Ferrari 456 and 456M are front-engined grand tourers which were produced by Ferrari from 1992 to 2003. The 456 was a replacement for the defunct front-engined 412 as the companys V12-powered four seater, the updated 456M, which was the last Ferrari model to use pop-up headlamps, was replaced in 2004 by the 612 Scaglietti. Pietro Camardella and Lorenzo Ramaciotti at Pininfarina designed the original 456 which was available in GT, the difference in name signifies the transmission, the former has a six-speed manual and the latter has a four-speed automatic developed in partnership with FF Developments, in Livonia, MI. This was only the automatic transmission ever offered by Ferrari. The 5.5 L 65° V12 engine was derived from the Dino V6 rather than the more conventional 60° V12s used in the 412 and it produced 442 PS with 4 valves per cylinder and Bosch Motronic M2.7 engine management. It could push the 1690 kg car and four passengers to 302 km/h making it the worlds fastest production four-seater, acceleration to 100 km/h was just 5.2 seconds, with a 13.4 second quarter-mile time.
At the time of its development it was the most powerful car ever developed by Ferrari. In 1996 engine was changed with Motronic M5.2 management, the name 456 is derived from the fact that each cylinder displaces 456 cubic centimeters. This was the last Ferrari to use this convention until the 488. Despite its supercar performance, the 456 has an unstressed engine. The chassis is a steel spaceframe construction with a one-piece composite bonnet. The body panels are welded to the chassis by using a special sandwich filler called feran that, approximately 3,289 of all versions were built. These consisted of the versions,456 GT,1,548,456 GTA,403, 456M GT,688. The Modificata 456M appeared in 1998, starting with chassis number 109589, many changes were made to improve aerodynamics and cooling, and the interior – still featuring Connolly Leather – was freshened with new seats and other conveniences. Some readily apparent changes can be seen in the two adjoining pictures, the 456 has a smaller grille with fog lights outside the grille.
The 456 had hood-mounted air scoops which can be removed on the 456M. The undercarriage spoiler on the 456M is fixed, where the older 456 had a spoiler that began its deployment above 105 km/h. The Tour de France Blue with Daytona Seats was the most desirable color, in the final year of production 2002/3 customers could specify their vehicle using the Carrozzeria Scaglietti Program
Front-engine, rear-wheel-drive layout
In automotive design, an FR, or front-engine, rear-wheel-drive layout is one where the engine is located at the front of the vehicle and driven wheels are located at the rear. This was the automobile layout for most of the 20th century. Modern designs commonly use the front-engine, front-wheel-drive layout, the first FR car was an 1895 Panhard model, so this layout was known as the Système Panhard in the early years. The layout has the advantage of minimizing mechanical complexity, as it allows the transmission to be placed in-line with the output shaft. In comparison, a vehicle with the engine over the driven wheels eliminates the need for the drive shaft, in order to reduce the relative weight of the drive shaft, the transmission was normally split into two parts, the gearbox and the final drive. The gearbox was produced with its highest gear being 1,1. The final drive, in the axle, would reduce this to the most appropriate speed for the wheels. As power is the product of torque and angular velocity, spinning the shaft faster for any given power reduces the torque, in an era when gasoline was cheap and cars were heavy, the mechanical advantages of the FR drivetrain layout made up for any disadvantage in weight terms.
It remained almost universal among car designs until the 1970s, after the Arab oil embargo of 1973 and the 1979 fuel crises, a majority of American FR vehicles were phased out for the FF layout – this trend would spawn the SUV-van conversion market. Throughout the 1980s and 1990s, most American companies set as a priority the eventual removal of rear-wheel drive from their mainstream, chrysler went 100% FF by 1990 and GMs American production went entirely FF by 1997 except the Corvette and Camaro. This configuration is referred to as a transaxle since the transmission. In Europe, front-wheel drive was popularized by small cars like the Mini, Renault 5 and Volkswagen Golf, upscale marques like Mercedes-Benz, BMW, and Jaguar remained mostly independent of this trend, and retained a lineup mostly or entirely made up of FR cars. Japanese mainstream marques such as Toyota were almost exclusively FR until the late 1970s, toyotas first FF vehicle was the Toyota Tercel, with the Corolla and Celica becoming FF while the Camry was designed as an FF from the beginning.
The Supra, Cressida and Century remained FR, luxury division Lexus has a mostly FR lineup. Subarus BRZ is an FR car, currently most cars are FF, including all front-engined economy cars, though FR cars are making a return as an alternative to large sport-utility vehicles. In North America, GM returned to production of FR-based luxury vehicles with the 2003 Cadillac CTS, as of 2012, all but the SRX and XTS are FR-based vehicles. Chevrolet reintroduced the FR-based Camaro in 2009, and the Caprice PPV in 2011, Pontiac had a short run with the FR-based G8 and Pontiac Solstice. A Chevrolet replacement for the G8 called the Chevrolet SS was released in 2013, chrysler and Dodge reintroduced the 300 and Charger on a FR platform
