Rolls-Royce Corniche
–
The Rolls-Royce Corniche is a two-door, front-engine, rear wheel drive five-seater manufactured and marketed by Rolls-Royce as a coupé and convertible from 1971 to 1995. The exterior design was by John Polwhele Blatchley, the model was assembled and finished in London at Mulliner Park Ward as continuation of the 1965 Silver Shadow coupe and 1966 drophead, with the Corniche name applied in March 1966. The Corniche was also sold as a Bentley, though that model became known as the Continental in 1984, the first car with the Corniche nameplate was a 1939 prototype based on the Bentley Mark V and never produced because of the onset of World War II. The Corniche nameplate stems from the originally French and Italian term for a coastal road, rolls Royce began marketing the Corniche in 1971, having registered the name in the 1930s. The original Corniche was a based on the Bentley Mark V featuring coachwork by the Paris firm. The single car undertook 15,000 miles of testing in Continental Europe before being blown up by a bomb at Dieppe while waiting at the dockside to be shipped to England. The Corniche, available as coupé or convertible, used the standard Rolls-Royce V8 engine with an alloy block. The bore was 4.1 in and the stroke was 3.9 in for a total of 6.75 L. Twin SU carburettors were initially fitted, desmogged export models retained the twin SUs until 1980, when Bosch fuel injection was added. A three-speed automatic transmission was standard, a four-wheel independent suspension with coil springs was augmented with a hydraulic self-levelling system, at first on all four, but later on the rear wheels only. Four wheel disc brakes were specified, with ventilated discs added for 1972, the car originally used a 119.75 in wheelbase. This was extended to 120 in in 1974 and 120.5 in in 1979, the Corniche received a mild restyling in the spring of 1977. Difference included rack-and-pinion steering, alloy and rubber bumpers, aluminium radiator, oil cooler, later changes included a modified rear independent suspension in March 1979. In March 1981, after the Silver Spirit had gone on sale, for 1985 there were also cosmetic and interior changes. Corniche models received Bosch KE/K-Jetronic fuel injection in 1977 and this engine, called the L410I, produced approximately 240 PS at just above 4,000 rpm for a top speed of 190 kilometres per hour. The Bentley version was updated in July 1984 with a new name, the Continental, revised and color-coded bumpers, rear view mirrors, production totaled 1090 Rolls-Royce Corniche Saloons,3239 Rolls-Royce Corniche Convertibles,69 Bentley Corniche Saloons and 77 Bentley Corniche Convertibles. The Corniche II name was applied for the United States market from 1986, anti-lock brakes were added for 1988, but air bags would not be available until the Corniche III. Also new for 1988 were some changes to the interior. Later in 1988 there was also a new reverse warning lens type and pattern around the license plate, as well as newly designed seats

Car classification
–
Governments and private organizations have developed car classification schemes that are used for innumerable purposes including regulation, description and categorization, among others. This article details commonly used classification schemes in use worldwide, vehicles can be categorized in numerous ways. Regulatory agencies may also establish a vehicle classification system for determining a tax amount, in the United Kingdom, a vehicle is taxed according to the vehicles construction, engine, weight, type of fuel and emissions, as well as the purpose for which it is used. Other jurisdictions may determine vehicle tax based upon environmental principles, such as the user pays principle, another standard for road vehicles of all types that is used internationally, is ISO 3833-1977. In the United States, since 2010 the Insurance Institute for Highway Safety uses a scheme it has developed that takes into account a combination of both shadow and weight. The United States Federal Highway Administration has developed a scheme used for automatically calculating road use tolls. There are two categories depending on whether the vehicle carries passengers or commodities. Vehicles that carry commodities are further subdivided by number of axles and number of units, the United States Environmental Protection Agency has developed a classification scheme used to compare fuel economy among similar vehicles. Passenger vehicles are classified based on a total interior passenger. Trucks are classified based upon their gross vehicle weight rating, heavy duty vehicles are not included within the EPA scheme. A similar set of classes is used by the Canadian EPA, in Australia, the Federal Chamber of Automotive Industries publishes its own classifications. This is a table listing several different methods of vehicle classification. Straddling the boundary between car and motorbike, these vehicles have engines under 1.0 litre, typically only two passengers, and are sometimes unorthodox in construction. Some microcars are three-wheelers, while the majority have four wheels, microcars were popular in post-war Europe, where their appearance led them to be called Bubble cars. More recent microcars are often electric powered, the size of ultracompact cars will be less than minicars, but have engine greater than 50cc displacement and able to transport 1 or 2 persons. Ultracompact cars cannot use standard, because of strict safety standards for minicars. The regulation about running capacity and safety performance of cars will be published in early autumn. Today, there are smaller than ultracompact cars, called category-1 motorized vehicles which it has 50cc displacement or less

Luxury vehicle
–
Luxury vehicle is a marketing term for a vehicle that provides luxury — pleasant or desirable features beyond strict necessity — at increased expense. The term is also broad, highly variable and relative and it is a perceptual, conditional and subjective attribute that may be comprehended differently by different people, What is a luxury car to some. Therefore, automakers differentiate among their product lines in collusion with the car-buying public, while a high price is the most frequent factor, it is styling, engineering, and even public opinion which cars had the highest and lowest status associated with them. Every era in history has had a group of car marques and models that have been expensive to purchase, due to their alleged superiority of their design. Aimed at wealthy buyers, such automobiles might be generically termed luxury cars and this term is also used for unique vehicles produced during an era when luxury was individualistic consideration, and coachwork could be tailored to an owner like a bespoke suit. Although there is literature about specific marques, there is a lack of systematic. Luxury vehicle makers may either be stand-alone companies in their own right, such as BMW and Mercedes-Benz, badge engineering is often used for cost savings, for example, the Lincoln vehicles that are based on Ford platforms or Acura models derived from Honda. Though widely used, the term luxury is broad and highly variable and it is a perceptual, conditional and subjective attribute and may be understood differently by different people, What is a luxury car to some. According to the European Commission, the luxury segment is classified as F-segment. However, the boundaries between the segments are increasingly becoming blurred and diluted as features once exclusive to luxury vehicles become standard equipment on even small cars. ACRISS is a system used by many car rental companies in the US for classifying vehicles. The system includes Luxury and Premium categories, Australia, In Australia, for taxation purposes a luxury car is defined as a passenger car whose value exceeds a certain threshold. France, In France the term voiture de luxe is used, Germany, In Germany the term Upper class is used. Russia, Russian markets use the term representative class vehicle, the classification varies, for instance Consumer Guide Automotive in the U. S. The premium compact segment is targeted at a market of consumers who found the existing entry-level luxury offerings to be too expensive. By offering a smaller, lighter, more fuel-efficient, and less expensive vehicle, premium compacts introduces younger buyers to the luxury marque, in hopes of retaining the coveted customer loyalty. This includes the Acura CSX, Audi A3, Buick Verano, BMW2 Series, BMW i3, Cadillac ELR, Chrysler 200, Lexus CT, Mercedes-Benz CLA-Class, Mercedes-Benz B-Class, Saab 9-2X, and the Volvo V40. Premium compacts compete with well-equipped midsize cars, and with options they overlap much with compact executive cars, Premium compacts may share components with mass market cars from the marques parent company, and/or have less sophisticated platforms compared to upmarket vehicles in the lineup

Convertible
–
A convertible or cabriolet is an automobile body style that can convert between an open-air mode and an enclosed one, varying in degree and means by model. Convertibles evolved from the phaeton, an open vehicle without glass side windows that sometimes had removable panels of fabric or other material for protection from the elements. Historically, a retractable roof consisted of a frame covered with a folding. A lesser seen detachable hardtop provided a more weatherproof and secure alternative, as technology improved, a retractable hardtop which removes and stows its own rigid roof in its trunk appeared, increasingly becoming the most popular form. A semiconvertible also known as a coach has a retractable or removable top which retains fully framed windows on its doors. A landaulet is a convertible with a fully enclosed front cabin. Other common terms include cabriolet, cabrio, soft top, and drop top, and where the roof is more than emergency weather protection, open two-seater, rag top, spider. The erected top secures to the frame header with manual latches, semimanual latches. The folded convertible top is called the stack, a tonneau cover provides a solution. A range of materials is available for soft tops, automakers had problems in securing raw materials to fulfill orders after World War II, including canvas in various shades for convertible tops and limiting their manufacture. Polyvinyl chloride material was used for many convertible tops, the material consists of two layers, a top layer made of PVC, which has a specific structure depending on the vehicle model, and a lower layer made of fabric. Side windows were not existent in open cars, which may have detachable side screens, rear windows have evolved similarly, with plastic rear windows appearing as late as the first-generation Porsche Boxster. Plastic windows can degrade, fade, yellow, and crack over time, a windblocker or wind deflector minimizes noise and rushing air reaching the occupants. Mazda pioneered a version on the RX7 convertible which featured an integral rigid opaque panel that folded up from behind the front seats, current convertibles feature windblockers of various designs including detachable fold-up designs, vertically retractable glass, minimal flaps – or other integrated wind controlling systems. According to the responsible for the 2008 Chrysler Sebring, its windblocker reduces wind noise by roughly 11 to 12 dB. Mercedes and Audi currently offer a heating duct to the area of the seat on SLK, SL. Windblockers are also available on the aftermarket for use on convertibles that do not have them, the Volvo C70 retractable hardtop includes a door-mounted side-impact protection inflatable curtain which inflates upward from the interior belt-line – vs. downward like the typical curtain airbag. The curtain has an extra stiff construction with double rows of slats that are offset from each other

Bentley Azure
–
The Bentley Azure is a large, four seater convertible built by Bentley Motors Limited at its factory in Crewe, England. The model debuted in 1995 on the Bentley Continental R platform and was produced until 2003, after a three-year break a completely new version powered by a significantly updated engine and riding on the newer Arnage platform debuted in 2006. According to 2009 research by internet company Yahoo, the Azure is the fourth most fuel consuming car on sale in the United Kingdom. The Azure debuted in March 1995 at the Geneva Motor Show on the platform of the Continental R model, which had been originally launched in 1991. Production only crept to a start, with a mere nine examples finished in the first year – in 1996, after production had started. Final assembly was carried out at Crewe. A roll-bar was never considered, which necessitated extensive reinforcing of the chassis, power came from the companys stalwart 6. With a zero to sixty miles per hour time of 6.3 seconds and a top speed of 241 km/h, new in 1995, the Azure was priced at $347,645 – $36,355 more than the Continental R on which it was based. One of limited editions included 2000 Symbolic Edition, an only 4-made Mulliner commission, *stated by Pininfarina production records**From 2 varying documents, newer data used Volkswagen purchased Bentley from Vickers in 1998, three years into production of the Mark 1 model. Volkswagen executives decided to keep the then-current Azure in production until 2003, production of the new Azure began for the 2006 model year. Now based on the Arnage platform, power came from the then-current variant of the Bentley turbocharged V8 making 450 hp and 645 lb·ft of torque, new Arnage was designed for the BMW4. 4-liter engine. A new, model-specific six-speed automatic transmission fed power to the rear wheels. Bentley claims a 0 to 60-mile-per-hour time of 5.6 seconds, the United States Department of Energy lists Bentley Azure as the least fuel-efficient car in its class with only 9 miles per US gallon city and 15 miles per US gallon highway rates. The T is a performance version of the Bentley Azure. The exterior styling was inspired from Bentley Mark VI, audio system includes large display audio head unit with Secure Digital memory card slot, iPod/USB/3.5 mm AUX interface, with optional Naim for Bentley 10-speaker, 1100W audio system. Electronic Stability Programme, Tire Pressure Monitoring System are now standard equipment, the twin turbocharged engine is rated 507 PS and 1,000 N·m torque. It has a 0–60 miles per hour time of 5.1 seconds, 0–100 mph time in 12.1 seconds, the car was unveiled at the LA Auto Show. The Azure had no immediate successor, Auto Show, Bentley unveiled a concept car built on the Mulsanne platform that follows the same formula as the two generations of Azure that proceeded it

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 also 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, Canada, 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, however, 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

United Kingdom
–
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, the United Kingdom includes the island of Great Britain, Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state—the Republic of Ireland. The Irish Sea lies between Great Britain and Ireland, with an area of 242,500 square kilometres, the United Kingdom is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants, together, this makes it the fourth-most densely populated country in the European Union. The United Kingdom is a monarchy with a parliamentary system of governance. The monarch is Queen Elizabeth II, who has reigned since 6 February 1952, other major urban areas in the United Kingdom include the regions of Birmingham, Leeds, Glasgow, Liverpool and Manchester. The United Kingdom consists of four countries—England, Scotland, Wales, the last three have devolved administrations, each with varying powers, based in their capitals, Edinburgh, Cardiff and Belfast, respectively. The relationships among the countries of the UK have changed over time, Wales was annexed by the Kingdom of England under the Laws in Wales Acts 1535 and 1542. A treaty between England and Scotland resulted in 1707 in a unified Kingdom of Great Britain, which merged in 1801 with the Kingdom of Ireland to form the United Kingdom of Great Britain and Ireland. Five-sixths of Ireland seceded from the UK in 1922, leaving the present formulation of the United Kingdom of Great Britain, there are fourteen British Overseas Territories. These are the remnants of the British Empire which, at its height in the 1920s, British influence can be observed in the language, culture and legal systems of many of its former colonies. The United Kingdom is a country and has the worlds fifth-largest economy by nominal GDP. The UK is considered to have an economy and is categorised as very high in the Human Development Index. It was the worlds first industrialised country and the worlds foremost power during the 19th, the UK remains a great power with considerable economic, cultural, military, scientific and political influence internationally. It is a nuclear weapons state and its military expenditure ranks fourth or fifth in the world. The UK has been a permanent member of the United Nations Security Council since its first session in 1946 and it has been a leading member state of the EU and its predecessor, the European Economic Community, since 1973. However, on 23 June 2016, a referendum on the UKs membership of the EU resulted in a decision to leave. The Acts of Union 1800 united the Kingdom of Great Britain, Scotland, Wales and Northern Ireland have devolved self-government

United States dollar
–
The United States dollar is the official currency of the United States and its insular territories per the United States Constitution. It is divided into 100 smaller cent units, the circulating paper money consists of Federal Reserve Notes that are denominated in United States dollars. The U. S. dollar was originally commodity money of silver as enacted by the Coinage Act of 1792 which determined the dollar to be 371 4/16 grain pure or 416 grain standard silver, the currency most used in international transactions, it is the worlds primary reserve currency. Several countries use it as their currency, and in many others it is the de facto currency. Besides the United States, it is used as the sole currency in two British Overseas Territories in the Caribbean, the British Virgin Islands and Turks and Caicos Islands. A few countries use the Federal Reserve Notes for paper money, while the country mints its own coins, or also accepts U. S. coins that can be used as payment in U. S. dollars. After Nixon shock of 1971, USD became fiat currency, Article I, Section 8 of the U. S. Constitution provides that the Congress has the power To coin money, laws implementing this power are currently codified at 31 U. S. C. Section 5112 prescribes the forms in which the United States dollars should be issued and these coins are both designated in Section 5112 as legal tender in payment of debts. The Sacagawea dollar is one example of the copper alloy dollar, the pure silver dollar is known as the American Silver Eagle. Section 5112 also provides for the minting and issuance of other coins and these other coins are more fully described in Coins of the United States dollar. The Constitution provides that a regular Statement and Account of the Receipts and that provision of the Constitution is made specific by Section 331 of Title 31 of the United States Code. The sums of money reported in the Statements are currently being expressed in U. S. dollars, the U. S. dollar may therefore be described as the unit of account of the United States. The word dollar is one of the words in the first paragraph of Section 9 of Article I of the Constitution, there, dollars is a reference to the Spanish milled dollar, a coin that had a monetary value of 8 Spanish units of currency, or reales. In 1792 the U. S. Congress passed a Coinage Act, Section 20 of the act provided, That the money of account of the United States shall be expressed in dollars, or units. And that all accounts in the offices and all proceedings in the courts of the United States shall be kept and had in conformity to this regulation. In other words, this act designated the United States dollar as the unit of currency of the United States, unlike the Spanish milled dollar the U. S. dollar is based upon a decimal system of values. Both one-dollar coins and notes are produced today, although the form is significantly more common

Turbocharger
–
Turbochargers were originally known as turbosuperchargers when all forced induction devices were classified as superchargers. Nowadays the term supercharger is usually applied only to mechanically driven forced induction devices, compared to a mechanically driven supercharger, turbochargers tend to be more efficient, but less responsive. Twincharger refers to an engine with both a supercharger and a turbocharger, turbochargers are commonly used on truck, car, train, aircraft, and construction equipment engines. They are most often used with Otto cycle and Diesel cycle internal combustion engines and they have also been found useful in automotive fuel cells. Forced induction dates from the late 19th century, when Gottlieb Daimler patented the technique of using a pump to force air into an internal combustion engine in 1885. During World War I French engineer Auguste Rateau fitted turbochargers to Renault engines powering various French fighters with some success, in 1918, General Electric engineer Sanford Alexander Moss attached a turbocharger to a V12 Liberty aircraft engine. Turbochargers were first used in aircraft engines such as the Napier Lioness in the 1920s. Ships and locomotives equipped with turbocharged diesel engines began appearing in the 1920s, turbochargers were also used in aviation, most widely used by the United States. During World War II, notable examples of U. S. aircraft with turbochargers include the B-17 Flying Fortress, B-24 Liberator, P-38 Lightning, and P-47 Thunderbolt. Turbochargers are widely used in car and commercial vehicles because they allow smaller-capacity engines to have improved fuel economy, reduced emissions, higher power, in contrast to turbochargers, superchargers are mechanically driven by the engine. Belts, chains, shafts, and gears are common methods of powering a supercharger, for example, on the single-stage single-speed supercharged Rolls-Royce Merlin engine, the supercharger uses about 150 horsepower. Yet the benefits outweigh the costs, for the 150 hp to drive the supercharger the engine generates an additional 400-horsepower, a net gain of 250 hp. This is where the principal disadvantage of a supercharger becomes apparent, another disadvantage of some superchargers is lower adiabatic efficiency as compared to turbochargers. Adiabatic efficiency is a measure of an ability to compress air without adding excess heat to that air. Even under ideal conditions, the compression process always results in elevated temperature, however. Roots superchargers impart significantly more heat to the air than turbochargers, thus, for a given volume and pressure of air, the turbocharged air is cooler, and as a result denser, containing more oxygen molecules, and therefore more potential power than the supercharged air. In practical application the disparity between the two can be dramatic, with turbochargers often producing 15% to 30% more power based solely on the differences in adiabatic efficiency. By comparison, a turbocharger does not place a direct mechanical load on the engine, although turbochargers place exhaust back pressure on engines, in contrast to supercharging, the primary disadvantage of turbocharging is what is referred to as lag or spool time

Wool
–
Wool is the textile fiber obtained from sheep and other animals, including cashmere and mohair from goats, qiviut from muskoxen, angora from rabbits, and other types of wool from camelids. Wool has several qualities that distinguish it from hair or fur, it is crimped, Wool is produced by follicles which are small cells located in the skin. These follicles are located in the layer of the skin called the epidermis. Follicles can be classed as primary or secondary follicles. Primary follicles produce three types of fiber, Kemp, medullated fibers and true wool fibers, secondary follicles only produce true wool fibers. Medullated fibers share nearly identical characteristics to hair and are long but lack crimp, Kemp fibers are very coarse and shed out. Wools scaling and crimp make it easier to spin the fleece by helping the individual fibers attach to each other, because of the crimp, wool fabrics have greater bulk than other textiles, and they hold air, which causes the fabric to retain heat. Wool has a specific heat coefficient, so it impedes heat transfer in general. This effect has benefited desert peoples, as Bedouins and Tuaregs use wool clothes for insulation, felting of wool occurs upon hammering or other mechanical agitation as the microscopic barbs on the surface of wool fibers hook together. The amount of crimp corresponds to the fineness of the wool fibers, a fine wool like Merino may have up to 100 crimps per inch, while coarser wool like karakul may have as few as one or two. In contrast, hair has little if any scale and no crimp, on sheep, the hair part of the fleece is called kemp. Wool fibers readily absorb moisture, but are not hollow, Wool can absorb almost one-third of its own weight in water. Wool absorbs sound like many other fabrics and it is generally a creamy white color, although some breeds of sheep produce natural colors, such as black, brown, silver, and random mixes. Wool ignites at a higher temperature than cotton and some synthetic fibers, Wool carpets are specified for high safety environments, such as trains and aircraft. Wool is usually specified for garments for firefighters, soldiers, Wool is considered by the medical profession to be allergenic. Sheep shearing is the process by which the fleece of a sheep is cut off. After shearing, the wool is separated into four categories, fleece, broken, bellies. In Australia before being auctioned, all Merino fleece wool is objectively measured for micron, yield, staple length, staple strength, the sheep is given a dip in antiseptic solution after shearing, so as to cure the wounds caused during shearing
