France became Europes dominant cultural, political, and military power under Louis XIV, in the 19th century Napoleon took power and established the First French Empire, whose subsequent Napoleonic Wars shaped the course of continental Europe. Following the collapse of the Empire, France endured a succession of governments culminating with the establishment of the French Third Republic in 1870. Following liberation in 1944, a Fourth Republic was established and later dissolved in the course of the Algerian War, the Fifth Republic, led by Charles de Gaulle, was formed in 1958 and remains to this day. Algeria and nearly all the colonies became independent in the 1960s with minimal controversy and typically retained close economic. France has long been a centre of art, science. It hosts Europes fourth-largest number of cultural UNESCO World Heritage Sites and receives around 83 million foreign tourists annually, France is a developed country with the worlds sixth-largest economy by nominal GDP and ninth-largest by purchasing power parity. In terms of household wealth, it ranks fourth in the world. France performs well in international rankings of education, health care, life expectancy, France remains a great power in the world, being one of the five permanent members of the United Nations Security Council with the power to veto and an official nuclear-weapon state. It is a member state of the European Union and the Eurozone.

Sydney
–
Sydney /ˈsɪdni/ is the state capital of New South Wales and the most populous city in Australia and Oceania. Located on Australias east coast, the metropolis surrounds the worlds largest natural harbour, residents of Sydney are known as Sydneysiders. The Sydney area has been inhabited by indigenous Australians for at least 30,000 years, the first British settlers, led by Captain Arthur Phillip, arrived in 1788 to found Sydney as a penal colony, the first European settlement in Australia. Since convict transportation ended in the century, the city has transformed from a colonial outpost into a major global cultural. As at June 2016 Sydneys estimated population was 5,005,358, in the 2011 census,34 percent of the population reported having been born overseas, representing many different nationalities and making Sydney one of the most multicultural cities in the world. There are more than 250 different languages spoken in Sydney and about one-third of residents speak a language other than English at home and it is classified as an Alpha+ World City by the Globalization and World Cities Research Network, indicating its influence in the region and throughout the world. Ranked eleventh in the world for economic opportunity, Sydney has a market economy with strengths in finance, manufacturing. Its gross regional product was $337 billion in 2013, the largest in Australia, there is a significant concentration of foreign banks and multinational corporations in Sydney and the city is promoted as one of Asia Pacifics leading financial hubs. Its natural features include Sydney Harbour, the Royal National Park, man-made attractions such as the Sydney Opera House, Sydney Tower and the Sydney Harbour Bridge are also well known to international visitors. The first people to inhabit the now known as Sydney were indigenous Australians having migrated from northern Australia. Radiocarbon dating suggests human activity first started to occur in the Sydney area from around 30,735 years ago, the earliest British settlers called them Eora people. Eora is the term the indigenous used to explain their origins upon first contact with the British. Its literal meaning is from this place, prior to the arrival of the British there were 4,000 to 8,000 native people in Sydney from as many as 29 different clans. Sydney Cove from Port Jackson to Petersham was inhabited by the Cadigal clan, the principal language groups were Darug, Guringai, and Dharawal. The earliest Europeans to visit the area noted that the people were conducting activities such as camping and fishing, using trees for bark and food, collecting shells. Development has destroyed much of the citys history including that of the first inhabitants, there continues to be examples of rock art and engravings located in the protected Ku-ring-gai Chase National Park. The first meeting between the people and the British occurred on 29 April 1770 when Lieutenant James Cook landed at Botany Bay on the Kurnell Peninsula. He noted in his journal that they were confused and somewhat hostile towards the foreign visitors, Cook was on a mission of exploration and was not commissioned to start a settlement

Australia
–
Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the worlds sixth-largest country by total area, the neighbouring countries are Papua New Guinea, Indonesia and East Timor to the north, the Solomon Islands and Vanuatu to the north-east, and New Zealand to the south-east. Australias capital is Canberra, and its largest urban area is Sydney, for about 50,000 years before the first British settlement in the late 18th century, Australia was inhabited by indigenous Australians, who spoke languages classifiable into roughly 250 groups. The population grew steadily in subsequent decades, and by the 1850s most of the continent had been explored, on 1 January 1901, the six colonies federated, forming the Commonwealth of Australia. Australia has since maintained a liberal democratic political system that functions as a federal parliamentary constitutional monarchy comprising six states. The population of 24 million is highly urbanised and heavily concentrated on the eastern seaboard, Australia has the worlds 13th-largest economy and ninth-highest per capita income. With the second-highest human development index globally, the country highly in quality of life, health, education, economic freedom. The name Australia is derived from the Latin Terra Australis a name used for putative lands in the southern hemisphere since ancient times, the Dutch adjectival form Australische was used in a Dutch book in Batavia in 1638, to refer to the newly discovered lands to the south. On 12 December 1817, Macquarie recommended to the Colonial Office that it be formally adopted, in 1824, the Admiralty agreed that the continent should be known officially as Australia. The first official published use of the term Australia came with the 1830 publication of The Australia Directory and these first inhabitants may have been ancestors of modern Indigenous Australians. The Torres Strait Islanders, ethnically Melanesian, were originally horticulturists, the northern coasts and waters of Australia were visited sporadically by fishermen from Maritime Southeast Asia. The first recorded European sighting of the Australian mainland, and the first recorded European landfall on the Australian continent, are attributed to the Dutch. The first ship and crew to chart the Australian coast and meet with Aboriginal people was the Duyfken captained by Dutch navigator, Willem Janszoon. He sighted the coast of Cape York Peninsula in early 1606, the Dutch charted the whole of the western and northern coastlines and named the island continent New Holland during the 17th century, but made no attempt at settlement. William Dampier, an English explorer and privateer, landed on the north-west coast of New Holland in 1688, in 1770, James Cook sailed along and mapped the east coast, which he named New South Wales and claimed for Great Britain. The first settlement led to the foundation of Sydney, and the exploration, a British settlement was established in Van Diemens Land, now known as Tasmania, in 1803, and it became a separate colony in 1825. The United Kingdom formally claimed the part of Western Australia in 1828. Separate colonies were carved from parts of New South Wales, South Australia in 1836, Victoria in 1851, the Northern Territory was founded in 1911 when it was excised from South Australia

North Acton, West Acton, East Acton, South Acton, Acton Green, Acton Town, Acton Vale, Acton means oak farm or farm by oak trees, and is derived from the Old English āc and tūn. Originally an ancient village, as London expanded, Acton became absorbed into the city, Acton and Harrow are the two locations with the most stations bearing their name anywhere in the United Kingdom, with seven each. Nowadays, the route linking London and Oxford bypasses central Acton. Actons name derives from the Old English words āc and tūn, later, in the Middle Ages tūn became a synonym for farm or farm by oak trees. For several centuries, its name bore the prefix Church to distinguish it from the hamlet of East Acton. Prehistoric settlement is shown by finds of Palaeolithic, Neolithic, and Bronze Age burials at Mill Hill Park, in the Middle Ages the northern half of the parish was heavily wooded. Landholders figuring in county records were resident by 1222 and houses were recorded from the late 13th century, the main settlement, Church Acton or Acton town, lay slightly west of the centre of the parish along the highway to Oxford at the 5-mile post out of London. By 1380 some of the tenements, such as The Tabard and The Cock, the hamlet of East Acton, mentioned in 1294, consisted of farmhouses and cottages north and south of common land known as East Acton green by 1474. Medieval settlement was mainly around the two hamlets, at Church Acton most of the farmhouses lay along the Oxford road or Horn Lane, with only a few outlying farms. Friars Place Farm at the end of Horn Lane and the moated site to the west. East of Friars Place farm were commons, Worton or Watton Green and Rush green in the 16th and 17th centuries, and Friars Place in the 18th century, to the north-west were Acton or Old Oak wells, known by 1613. Gregories, mentioned in 1551 as a tenement with 30 a. near Bollo Lane. Londoners were increasingly involved in sales from the early 14th century. The manor, part of Fulham, had no resident lord,1735, when a branch of the landed Somerset family lived in Acton, there were no large resident landowners. Many of the tenements without land, including most of the inns, by the 17th century Actons proximity to London had made it a summer retreat for courtiers and lawyers.

England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west, the Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east, the country covers five-eighths of the island of Great Britain in its centre and south, and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight. England became a state in the 10th century, and since the Age of Discovery. The Industrial Revolution began in 18th-century England, transforming its society into the worlds first industrialised nation, Englands terrain mostly comprises low hills and plains, especially in central and southern England. However, there are uplands in the north and in the southwest, the capital is London, which is the largest metropolitan area in both the United Kingdom and the European Union. In 1801, Great Britain was united with the Kingdom of Ireland through another Act of Union to become the United Kingdom of Great Britain and Ireland. In 1922 the Irish Free State seceded from the United Kingdom, leading to the latter being renamed the United Kingdom of Great Britain, the name England is derived from the Old English name Englaland, which means land of the Angles. The Angles were one of the Germanic tribes that settled in Great Britain during the Early Middle Ages, the Angles came from the Angeln peninsula in the Bay of Kiel area of the Baltic Sea. The earliest recorded use of the term, as Engla londe, is in the ninth century translation into Old English of Bedes Ecclesiastical History of the English People. According to the Oxford English Dictionary, its spelling was first used in 1538. The earliest attested reference to the Angles occurs in the 1st-century work by Tacitus, Germania, the etymology of the tribal name itself is disputed by scholars, it has been suggested that it derives from the shape of the Angeln peninsula, an angular shape. An alternative name for England is Albion, the name Albion originally referred to the entire island of Great Britain. The nominally earliest record of the name appears in the Aristotelian Corpus, specifically the 4th century BC De Mundo, in it are two very large islands called Britannia, these are Albion and Ierne. But modern scholarly consensus ascribes De Mundo not to Aristotle but to Pseudo-Aristotle, the word Albion or insula Albionum has two possible origins. Albion is now applied to England in a poetic capacity. Another romantic name for England is Loegria, related to the Welsh word for England, Lloegr, the earliest known evidence of human presence in the area now known as England was that of Homo antecessor, dating to approximately 780,000 years ago. The oldest proto-human bones discovered in England date from 500,000 years ago, Modern humans are known to have inhabited the area during the Upper Paleolithic period, though permanent settlements were only established within the last 6,000 years

Japanese people make up 98. 5% of Japans total population, approximately 9.1 million people live in the city of Tokyo, the capital of Japan. Archaeological research indicates that Japan was inhabited as early as the Upper Paleolithic period, the first written mention of Japan is in Chinese history texts from the 1st century AD. Influence from other regions, mainly China, followed by periods of isolation, from the 12th century until 1868, Japan was ruled by successive feudal military shoguns who ruled in the name of the Emperor. Japan entered into a period of isolation in the early 17th century. The Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the bombings of Hiroshima and Nagasaki. Japan is a member of the UN, the OECD, the G7, the G8, the country has the worlds third-largest economy by nominal GDP and the worlds fourth-largest economy by purchasing power parity. It is also the worlds fourth-largest exporter and fourth-largest importer, although Japan has officially renounced its right to declare war, it maintains a modern military with the worlds eighth-largest military budget, used for self-defense and peacekeeping roles. Japan is a country with a very high standard of living. Its population enjoys the highest life expectancy and the third lowest infant mortality rate in the world, in ancient China, Japan was called Wo 倭. It was mentioned in the third century Chinese historical text Records of the Three Kingdoms in the section for the Wei kingdom, Wa became disliked because it has the connotation of the character 矮, meaning dwarf.

Valladolid is a city in Spain and the de facto capital of the autonomous community of Castile and León. It has a population of 309,714 people, making it Spains 13th most populous municipality and its metropolitan area ranks 20th in Spain with a population of 414,244 people in 23 municipalities. The city is situated at the confluence of the Pisuerga and Esgueva rivers, and located within five winegrowing regions, Ribera del Duero, Rueda, Toro, Tierra de León, Valladolid was originally settled in pre-Roman times by the Celtic Vaccaei people, and later the Romans themselves. It remained a settlement until being re-established by King Alfonso VI of Castile as a Lordship for the Count Pedro Ansúrez in 1072. The Catholic Monarchs, Isabel I of Castile and Ferdinand II of Aragon, married in Valladolid in 1469 and established it as the capital of the Kingdom of Castile and later of united Spain. Christopher Columbus died in Valladolid in 1506, while authors Francisco de Quevedo, the city was briefly the capital of Habsburg Spain under Phillip III between 1601 and 1606, before returning indefinitely to Madrid. The city then declined until the arrival of the railway in the 19th century, among the events that are held each year in the city there is Holy Week, Valladolid International Film Week, and the Theatre Festival and street arts. There is no evidence for the origin of the modern name of Valladolid. Another theory suggests that the name derives from the Arabic expression Ballad Al-Walid بلد الوليد, yet a third claims that it derives from Vallis Olivetum, meaning valley of the olives. In texts from the ages the town is called Vallisoletum, meaning sunny valley. The city is popularly called Pucela, a nickname whose origin is not clear. Another theory is that Pucela comes from the fact that Pozzolana cement was sold there, the Vaccaei was a Celtic tribe, the first people with stable presence on the sector of the middle valley of the River Duero documented in historical times. Remains of Celtiberian and of a Roman camp have been excavated near the city, the nucleus of the city was originally located in the area of the current San Miguel y el Rosarillo square, and was surrounded by a palisade.

Spain
–
By population, Spain is the sixth largest in Europe and the fifth in the European Union. Spains capital and largest city is Madrid, other urban areas include Barcelona, Valencia, Seville, Bilbao. Modern humans first arrived in the Iberian Peninsula around 35,000 years ago, in the Middle Ages, the area was conquered by Germanic tribes and later by the Moors. Spain is a democracy organised in the form of a government under a constitutional monarchy. It is a power and a major developed country with the worlds fourteenth largest economy by nominal GDP. Jesús Luis Cunchillos argues that the root of the span is the Phoenician word spy. Therefore, i-spn-ya would mean the land where metals are forged, two 15th-century Spanish Jewish scholars, Don Isaac Abravanel and Solomon ibn Verga, gave an explanation now considered folkloric. Both men wrote in two different published works that the first Jews to reach Spain were brought by ship by Phiros who was confederate with the king of Babylon when he laid siege to Jerusalem. This man was a Grecian by birth, but who had given a kingdom in Spain. He became related by marriage to Espan, the nephew of king Heracles, Heracles later renounced his throne in preference for his native Greece, leaving his kingdom to his nephew, Espan, from whom the country of España took its name. Based upon their testimonies, this eponym would have already been in use in Spain by c.350 BCE, Iberia enters written records as a land populated largely by the Iberians, Basques and Celts. Early on its coastal areas were settled by Phoenicians who founded Western Europe´s most ancient cities Cadiz, Phoenician influence expanded as much of the Peninsula was eventually incorporated into the Carthaginian Empire, becoming a major theater of the Punic Wars against the expanding Roman Empire. After an arduous conquest, the peninsula came fully under Roman Rule, during the early Middle Ages it came under Germanic rule but later, much of it was conquered by Moorish invaders from North Africa. In a process took centuries, the small Christian kingdoms in the north gradually regained control of the peninsula. The last Moorish kingdom fell in the same year Columbus reached the Americas, a global empire began which saw Spain become the strongest kingdom in Europe, the leading world power for a century and a half, and the largest overseas empire for three centuries. Continued wars and other problems led to a diminished status. The Napoleonic invasions of Spain led to chaos, triggering independence movements that tore apart most of the empire, eventually democracy was peacefully restored in the form of a parliamentary constitutional monarchy. Spain joined the European Union, experiencing a renaissance and steady economic growth

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

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

Inline-four engine
–
The inline-four engine or straight-four engine is a type of inline internal combustion four-cylinder engine with all four cylinders mounted in a straight line, or plane along the crankcase. The single bank of cylinders may be oriented in either a vertical or a plane with all the pistons driving a common crankshaft. Where it is inclined, it is called a slant-four. In a specification chart or when an abbreviation is used, an engine is listed either as I4 or L4. The inline-four layout is in primary balance and confers a degree of mechanical simplicity which makes it popular for economy cars. However, despite its simplicity, it suffers from an imbalance which causes minor vibrations in smaller engines. These vibrations become more powerful as engine size and power increase, the inline-four is the most common engine configuration in modern cars, while the V6 engine is the second most popular. This inline engine configuration is the most common in cars with a displacement up to 3.0 L, in practice, the displacement of inline-four petrol engines in cars rarely exceeds this figure. For example, the largest engine of this form on the U. S. market in model year 2015 is the Toyota 2TR-FE, however, there are some notable exceptions. Early vehicles also tended to have engines with larger displacements to develop horsepower, the Model A Ford was built with a 3.3 L inline-four engine. Inline-four diesel engines, which are lower revving than gasoline engines, Mitsubishi still employs a 3.0 L inline-four diesel. Generally, European and Asian manufacturers of trucks with a vehicle weight rating between 7.5 and 18 tonnes use inline four-cylinder diesel engines with displacements around 5 L. The MAN D0834 engine is a 4.6 L inline-4 with 220 hp and 627 lb·ft, the Isuzu Forward is a medium-duty truck which is available with a 5.2 L inline-four engine that delivers 210 hp and 470 lb·ft. The Hino Ranger is a medium-duty truck which is available with a 5.1 L inline-four engine that delivers 175 hp and 465 lb·ft, the earlier Hino Ranger even had a 5.3 L inline-four engine. The Kubota M135X is a tractor with a 6.1 L inline-four and this turbo-diesel engine has a bore of 118 mm and a relatively long stroke of 140 mm. One of the strongest Powerboat-4-cylinders is the Volvo Penta D4-300 turbodiesel and this is a 3.7 L-inline-4 with 300 hp and 516 lb·ft. Brunswick Marine built a 127 kW3.7 L 4-cylinder gasoline engine for their Mercruiser Inboard/outboard line, the block was formed from one half of a Ford 460 cubic inch V8 engine. This engine was produced in the 1970s and 1980s, One of the largest inline-four engines is the MAN B&W 4K90 marine engine
