Tehran is the capital of Iran and Tehran Province. With a population of around 8.7 million in the city and 15 million in the larger metropolitan area of Greater Tehran, Tehran is the most populous city in Iran and Western Asia, has the second-largest metropolitan area in the Middle East. It is ranked 24th in the world by the population of its metropolitan area. In the Classical era, part of the territory of present-day Tehran was occupied by Rhages, a prominent Median city, it was subject to destruction through the medieval Arab and Mongol invasions. Its modern-day inheritor remains as an urban area absorbed into the metropolitan area of Greater Tehran. Tehran was first chosen as the capital of Iran by Agha Mohammad Khan of the Qajar dynasty in 1796, in order to remain within close reach of Iran's territories in the Caucasus, before being separated from Iran as a result of the Russo-Iranian Wars, to avoid the vying factions of the ruling Iranian dynasties; the capital has been moved several times throughout the history, Tehran is the 32nd national capital of Iran.
Large scale demolition and rebuilding began in the 1920s, Tehran has been a destination for mass migrations from all over Iran since the 20th century. Tehran is home to many historical collections, including the royal complexes of Golestan, Sa'dabad, Niavaran, where the two last dynasties of the former Imperial State of Iran were seated. Tehran's most famous landmarks include the Azadi Tower, a memorial built under the reign of Mohammad Reza Shah of the Pahlavi dynasty in 1971 to mark the 2,500th year of the foundation of the Imperial State of Iran, the Milad Tower, the world's sixth-tallest self-supporting tower, completed in 2007; the Tabiat Bridge, a newly-built landmark, was completed in 2014. The majority of the population of Tehran are Persian-speaking people, 99% of the population understand and speak Persian, but there are large populations of other ethno-linguistic groups who live in Tehran and speak Persian as a second language. Tehran has an international airport, a domestic airport, a central railway station, the rapid transit system of Tehran Metro, a bus rapid transit system, a large network of highways.
There have been plans to relocate Iran's capital from Tehran to another area, due to air pollution and the city's exposure to earthquakes. To date, no definitive plans have been approved. A 2016 survey of 230 cities by consultant Mercer ranked Tehran 203rd for quality of life. According to the Global Destinations Cities Index in 2016, Tehran is among the top ten fastest growing destinations. October 6 is marked as Tehran Day based on a 2016 decision by members of the City Council, celebrating the day when the city was chosen as the capital of Iran by the Qajar dynasty back in 1907; the origin of the name Tehran is uncertain. Prior to Tehran being the capital of Iran Isfahan was the capital. Isfahan has a significant Armenian Population; the settlement of Tehran dates back over 7,000 years. Tehran is situated within the historical region of Media in northwestern Iran. By the time of the Median Empire, a part of the territory of present-day Tehran was a suburb of the prominent Median city of Rhages.
In the Avesta's Videvdat, Rhages is mentioned as the 12th sacred place created by Ohrmazd. In Old Persian inscriptions, Rhages appears as a province. From Rhages, Darius I sent reinforcements to his father Hystaspes, putting down the rebellion in Parthia. In some Middle Persian texts, Rhages is given as the birthplace of Zoroaster, although modern historians place the birth of Zoroaster in Khorasan. Rhages's modern-day inheritor, Ray, is a city located towards the southern end of Tehran, absorbed into the metropolitan area of Greater Tehran. Mount Damavand, the highest peak of Iran, located near Tehran, is an important location in Ferdowsi's Šāhnāme, the Iranian epic poem, based on the ancient legends of Iran, it appears in the epics as the homeland of the protoplast Keyumars, the birthplace of king Manuchehr, the place where king Freydun binds the dragon fiend Aždahāk, the place where Arash shot his arrow from. During the reign of the Sassanian Empire, in 641, Yazdgerd III issued his last appeal to the nation from Rhages, before fleeing to Khorasan.
Rhages was dominated by the Parthian Mehran family, Siyavakhsh—the son of Mehran the son of Bahram Chobin—who resisted the 7th-century Muslim invasion of Iran. Because of this resistance, when the Arabs captured Rhages, they ordered the town to be destroyed and rebuilt anew by traitor aristocrat Farrukhzad. In the 9th century, Tehran was a well-known village, but less known than the city of Rhages, flourishing nearby. Rhages was described in detail by 10th-century Muslim geographers. Despite the interest that Arabian Baghdad displayed in Rhages, the number of Arabs in the city remained insignificant and the population consisted of Iranians of all classes; the Oghuz Turks invaded Rhages discretely in 1035 and 1042, but the city was recovered under the reigns of the Seljuks and the Khwarezmians. Medieval writer Najm od Din Razi declared the population of Rhages about 500,000 before the Mongol invasion. In the 13th century, the Mongols invaded Rhages, laid the city in ruins, massacred many of its inhabitants.
Following the invasion, many of the city's inhabitants escaped to Tehran. In July 1404, Castilian ambassador Ruy González de Clavijo visited Tehran while on a journey to Samarkand, the capital of Turco-Mongol conqueror Timur, who ruled Iran at the time. In his diary, Tehran was described as an unwalled region. Ital
The automotive industry is a wide range of companies and organizations involved in the design, manufacturing and selling of motor vehicles. It is one of the world's largest economic sectors by revenue; the automotive industry does not include industries dedicated to the maintenance of automobiles following delivery to the end-user, such as automobile repair shops and motor fuel filling stations. The word automotive is from the Greek autos, Latin motivus to refer to any form of self-powered vehicle; this term, as proposed by Elmer Sperry, first came into use with reference to automobiles in 1898. The automotive industry began in the 1860s with hundreds of manufacturers that pioneered the horseless carriage. For many decades, the United States led the world in total automobile production. In 1929, before the Great Depression, the world had 32,028,500 automobiles in use, the U. S. automobile industry produced over 90% of them. At that time the U. S. had one car per 4.87 persons. After World War II, the U.
S. produced about 75 percent of world's auto production. In 1980, the U. S. was overtaken by Japan and became world's leader again in 1994. In 2006, Japan narrowly passed the U. S. in production and held this rank until 2009, when China took the top spot with 13.8 million units. With 19.3 million units manufactured in 2012, China doubled the U. S. production, with 10.3 million units, while Japan was in third place with 9.9 million units. From 1970 over 1998 to 2012, the number of automobile models in the U. S. has grown exponentially. Safety is a state that implies to be protected from any risk, damage or cause of injury. In the automotive industry, safety means that users, operators or manufacturers do not face any risk or danger coming from the motor vehicle or its spare parts. Safety for the automobiles themselves, implies that there is no risk of damage. Safety in the automotive industry is important and therefore regulated. Automobiles and other motor vehicles have to comply with a certain number of norms and regulations, whether local or international, in order to be accepted on the market.
The standard ISO 26262, is considered as one of the best practice framework for achieving automotive functional safety. In case of safety issues, product defect or faulty procedure during the manufacturing of the motor vehicle, the maker can request to return either a batch or the entire production run; this procedure is called product recall. Product recalls happen in every industry and can be production-related or stem from the raw material. Product and operation tests and inspections at different stages of the value chain are made to avoid these product recalls by ensuring end-user security and safety and compliance with the automotive industry requirements. However, the automotive industry is still concerned about product recalls, which cause considerable financial consequences. Around the world, there were about 806 million cars and light trucks on the road in 2007, consuming over 980 billion litres of gasoline and diesel fuel yearly; the automobile is a primary mode of transportation for many developed economies.
The Detroit branch of Boston Consulting Group predicts that, by 2014, one-third of world demand will be in the four BRIC markets. Meanwhile, in the developed countries, the automotive industry has slowed down, it is expected that this trend will continue as the younger generations of people no longer want to own a car anymore, prefer other modes of transport. Other powerful automotive markets are Iran and Indonesia. Emerging auto markets buy more cars than established markets. According to a J. D. Power study, emerging markets accounted for 51 percent of the global light-vehicle sales in 2010; the study, performed in 2010 expected this trend to accelerate. However, more recent reports confirmed the opposite. In the United States, vehicle sales peaked in 2000, at 17.8 million units. The OICA counts over 50 countries which assemble, manufacture or disseminate automobiles. Of that figure, only 13, boldfaced in the list below, possess the capability to design automobiles from the ground up; this is a list of the 15 largest manufacturers by production in 2016.
It is common for automobile manufacturers to hold stakes in other automobile manufacturers. These ownerships can be explored under the detail for the individual companies. Notable current relationships include: Daimler AG holds a 10.0% stake in KAMAZ. Daimler AG holds an 89.29% stake in Mitsubishi Fuso Truck and Bus Corporation. Daimler AG holds a 3.1% in the Renault-Nissan Alliance. Daimler AG holds a 12% stake in Beijing Automotive Group, Daimler AG holds an 85% stake in Master Motors. Dongfeng Motor holds a 12.23% stake and a 19.94% exercisable voting rights in PSA Groupe. FAW Group owns 49% of Haima Automobile. FCA holds a 10% stake in Ferrari. FCA holds a 67% stake in Fiat Automobili Srbija. FCA holds 37.8% of Tofaş with another 37.8% owned by Koç Holding. Fiat Automobili Srbija owns a 54% stake in Zastava Trucks. Fiat Industrial owns a 46% stake in Zastava Trucks. Fujian Motors Group holds a 15% stake in King Long. FMG, Beijing Automotive Group, China Motor, Daimler has a joint venture called Fujian Benz.
FMG, China Motor, Mitsubishi Motors has a joint venture called Soueast, FMG holds a 50% stake, both China Motor and Mitsubishi Motors holds an equal 25% stake. Geely Automobile holds a 23% stake in The London Taxi Company. Geely Automobile holds a 49.9% stake in PROTON Holdings and a 51% stake in Lotus Cars. Geely Holding Group holds a 9.69% stake in Daimle
A sedan — saloon — is a passenger car in a three-box configuration with separate compartments for engine and cargo. Sedan's first recorded use as a name for a car body was in 1912; the name comes from a 17th century development of a litter, the sedan chair, a one-person enclosed box with windows and carried by porters. Variations of the sedan style of body include: close-coupled sedan, club sedan, convertible sedan, fastback sedan, hardtop sedan, notchback sedan and sedanet/sedanette; the current definition of a sedan is a car with a closed body with the engine and cargo in separate compartments. This broad definition does not differentiate sedans from various other car body styles, but in practice the typical characteristics of sedans are: a B-pillar that supports the roof two rows of seats a three-box design with the engine at the front and the cargo area at the rear a less steeply sloping roofline than a coupé, which results in increased headroom for rear passenger and a less sporting appearance.
A rear interior volume of at least 33 cu ft It is sometimes suggested that sedans must have four doors. However, several sources state that a sedan can have four doors. In addition, terms such as sedan and coupé have been more loosely interpreted by car manufacturers since 2010; when a manufacturer produces two-door sedan and four-door sedan versions of the same model, the shape and position of the greenhouse on both versions may be identical, with only the B-pillar positioned further back to accommodate the longer doors on the two-door versions. A sedan chair, a sophisticated litter, was an enclosed box with windows used to transport one seated person. Porters at the front and rear carried the chair with horizontal poles. Litters date back to long before ancient Egypt and China. Sedan chairs were developed in the 1630s. Reputable etymologists suggest the name of the chair probably came through Italian dialects from the Latin sedere meaning to sit; the same experts report that the first recorded use of sedan for an automobile body occurred in 1912 when a new Studebaker model was described by its manufacturers as a sedan.
The same American dictionary provides this description: "Sedan an enclosed automobile for four or more people, having two or four doors". There were enclosed automobile bodies before 1912. Long before that time the same enclosed but horse-drawn carriages were known as broughams in the United Kingdom, they were berlinas in France and Italy. Both names are still used there for sedans. There is an unsubstantiated claim that the body of a particular 1899 Renault Voiturette Type B was the first motor vehicle, a sedan, it was a two-door two-seater vehicle with an extra external seat for a footman/mechanic. Georgano claims the earliest usage matching a modern definition of a sedan was a 1911 Speedwell sedan manufactured in the United States. In American English and Latin American Spanish, the term sedan is used. In British English, a car of this configuration is called a saloon. Hatchback sedans are known as hatchbacks. Super saloon is used to describe a high performance saloon car where sports saloon would have been used in the past.
Saloon has been used by British car manufacturers in the United States, for example, the Rolls-Royce Park Ward. In Australia and New Zealand sedan is now predominantly used, they were simply cars. In the 21st century saloon is still found in the long-established names of particular motor races. In other languages, sedans are known as berlina though they may include hatchbacks; these names, like sedan, all come from forms of passenger transport used before the advent of automobiles. In German sedans are berlines or limousines and limousines are stretch-limousines. In the United States notchback sedan distinguishes models with a horizontal trunklid; the term is only referred to in the marketing when it is necessary to distinguish between two sedan body styles of the same model range. Several sedans have a fastback profile, but instead of a trunk lid, the entire back of the vehicle lifts up. Examples include the Chevrolet Malibu Maxx, Audi A5 Sportback and Tesla Model S; the names "hatchback" and "sedan" are used to differentiate between body styles of the same model.
Therefore the term "hatchback sedan" is not used, to avoid confusion. There have been many sedans with a fastback style. Hardtop sedans were a popular body style in the United States from the 1950s to the 1970s. Hardtops are manufactured without a B-pillar leaving uninterrupted open space or, when closed, glass along the side of the car; the top was intended to look like a convertible's top but it was fixed and made of hard material that did not fold. All manufacturers in the United States from the early 1950s into the 1970s provided at least a 2-door hardtop model in their range and, if their engineers could manage it, a 4-door hardtop as well; the lack of side-bracing demanded a strong and heavy chassis frame to combat unavoidable flexing. The fashion may have delayed the introduction of unibody construction. In 1973 the US government passed Federal Motor Vehicle Safety Standard 216 creating a standard roof strength test to measure the integrity of roof structure in motor vehicles to come into effect some years later.
Pininfarina S.p. A. is coachbuilder, with headquarters in Cambiano, Italy. It was founded by Battista "Pinin" Farina in 1930. On 14 December 2015, Mahindra Group acquired Pininfarina S.p. A. for about €168 million. Pininfarina is employed by a wide variety of automobile manufacturers to design vehicles; these firms have included long-established customers such as Ferrari, Alfa Romeo, Fiat, GM, Maserati, to emerging companies in the Asian market with Chinese manufactures like AviChina, Changfeng, JAC and Korean manufacturers Daewoo and Hyundai. Since the 1980s Pininfarina has designed high-speed trains, trams, rolling stocks, automated light rail cars, people movers, yachts and private jets. With the 1986 creation of "Pininfarina Extra" it has consulted on industrial design, interior design and graphic design. Pininfarina was run by Battista's son Sergio Pininfarina until 2001 his grandson Andrea Pininfarina until his death in 2008. After Andrea's death, his younger brother Paolo Pininfarina was appointed as CEO.
At its height in 2006 the Pininfarina Group employed 2,768 with subsidiary company offices throughout Europe, as well as in Morocco and the United States. As of 2012 with the end of series automotive production, employment has shrunk to 821. Pininfarina is publicly traded on the Borsa Italiana; when automobile designer and builder Battista "Pinin" Farina broke away from his brother's coach building firm, Stabilimenti Farina, in 1928, he founded "Carrozzeria Pinin Farina" with financial help from his wife's family and Vincenzo Lancia. That first year the firm employed built 50 automobile bodies. On 22 May 1930 papers were filed to become a corporation, Società anonima Carrozzeria Pinin Farina headquartered in Turin, Italy, at 107 Corso Trapani. During the 1930s, the company built bodies for Lancia, Alfa Romeo, Isotta Fraschini, Hispano-Suiza, Fiat and Rolls-Royce. With its close relationship with Lancia, the pioneer of the monocoque in automobile design, Farina became the first coachbuilder to build bodies for the new technique known as unibody construction.
This development happened in the mid-1930s when others saw the frameless construction as the end of the independent coachbuilder. In 1939, World War II ended automobile production, but the company had 400 employees building 150 bodies a month; the war effort against the Allies brought work making ambulances and searchlight carriages. The Pinin Farina factory was destroyed by Allied bombers ending the firm's operations. After the war, Italy was banned from the 1946 Paris Motor Show; the Paris show was attended by 809,000 visitors, queues stretched from the main gate all the way to the Seine. Pinin Farina and his son Sergio, determined to defy the ban, drove two of their cars from Turin to Paris, found a place at the entrance to the exhibition to display the two new creations; the managers of the Grand Palais said of the display, "the devil Pinin Farina", but to the press and the public it was the successful "Turin coachbuilder's anti-salon". At the end of 1945 the Cisitalia 202 Coupé was designed.
An elegantly proportioned design with a low hood, it is the car, given credit for establishing Pinin Farina's reputation. The Pinin Farina design was honored in the Museum of Modern Art's landmark presentation "Eight Automobiles" in 1951. A total of 170 Coupés were produced by Pinin Farina; the publicity of the Museum of Modern Art exhibit brought Pinin Farina to the attention of Nash-Kelvinator managers. The subsequent cooperation with Nash Motors resulted in high-volume production of Pinin Farina designs and provided a major entry into the United States market. In 1952, Farina visited the U. S. for the unveiling of his design for the Nash Ambassador and Statesman lines, although they did carry some details of Pinin Farina's design, were designed by Nash's then-new in-house styling staff when the original Farina-designed model proved unsuited to American tastes, exhibiting a popular 1950s appearance called "ponton". The Nash-Healey sports car body was, however designed and assembled in limited numbers from 1952 to 1954 at Pinin Farina's Turin facilities.
Nash advertised its link to the famous Italian designer, much as Studebaker promoted its longtime association with Raymond Loewy. As a result of Nash's million advertising campaign, Pinin Farina became well known in the U. S. Pinin Farina built the bodies for the limited-series Cadillac Eldorado Brougham for General Motors in 1959 and 1960, assembled them and sent them back to the U. S. There were 99 Broughams built in 1959 and 101 in 1960. A similar arrangement was repeated in the late 1980s when Pininfarina designed the Cadillac Allanté at the San Giusto Canavese factory; the car bodies were assembled and painted in Italy before being flown from the Turin International Airport to Detroit for final vehicle assembly. It started in 1951 with a meeting at a restaurant in Tortona, a small town halfway between Turin and Modena; this neutral territory was chosen because neither Farina nor Enzo Ferrari wanted to meet at the other's headquarters. Pinin’s son, Sergio Pininfarina recalled, "It is not difficult to imagine how I felt that afternoon when my father, without taking his eyes off the road for one moment told me his decision as we drove back to Turin: "From now on you'll be looking after Ferrari, from A to Z. Design, technology, construction—the lot!"—I was over the moon with happiness."
"Since that meeting the only road-going production Ferraris not designed by P
A petrol engine is an internal combustion engine with spark-ignition, designed to run on petrol and similar volatile fuels. In most petrol engines, the fuel and air are mixed after compression; the pre-mixing was done in a carburetor, but now it is done by electronically controlled fuel injection, except in small engines where the cost/complication of electronics does not justify the added engine efficiency. The process differs from a diesel engine in the method of mixing the fuel and air, in using spark plugs to initiate the combustion process. In a diesel engine, only air is compressed, the fuel is injected into hot air at the end of the compression stroke, self-ignites; the first practical petrol engine was built in 1876 in Germany by Nikolaus August Otto, although there had been earlier attempts by Étienne Lenoir, Siegfried Marcus, Julius Hock and George Brayton. With both air and fuel in a closed cylinder, compressing the mixture too much poses the danger of auto-ignition — or behaving like a diesel engine.
Because of the difference in burn rates between the two different fuels, petrol engines are mechanically designed with different timing than diesels, so to auto-ignite a petrol engine causes the expansion of gas inside the cylinder to reach its greatest point before the cylinder has reached the "top dead center" position. Spark plugs are set statically or at idle at a minimum of 10 degrees or so of crankshaft rotation before the piston reaches T. D. C, but at much higher values at higher engine speeds to allow time for the fuel-air charge to complete combustion before too much expansion has occurred - gas expansion occurring with the piston moving down in the power stroke. Higher octane petrol burns slower, therefore it has a lower propensity to auto-ignite and its rate of expansion is lower. Thus, engines designed to run high-octane fuel can achieve higher compression ratios. Most modern automobile petrol engines have a compression ratio of 10.0:1 to 13.5:1. Engines with a knock sensor can and have C.
R higher than 11.1:1 and approaches 14.0:1 and engines without a knock sensor have C. R of 8.0:1 to 10.5:1. Petrol engines run at higher rotation speeds than diesels due to their lighter pistons, connecting rods and crankshaft and due to petrol burning more than diesel; because pistons in petrol engines tend to have much shorter strokes than pistons in diesel engines it takes less time for a piston in a petrol engine to complete its stroke than a piston in a diesel engine. However, the lower compression ratios of petrol engines give petrol engines lower efficiency than diesel engines. Most petrol engines have 20% thermal efficiency, nearly half of diesel engines; however some newer engines are reported to be much more efficient than previous spark-ignition engines. Petrol engines have many applications, including: Automobiles Motorcycles Aircraft Motorboats Small engines, such as lawn mowers and portable engine-generators Before the use of diesel engines became widespread, petrol engines were used in buses, lorries and a few railway locomotives.
Examples: Bedford OB bus Bedford M series lorry GE 57-ton gas-electric boxcab locomotive Petrol engines may run on the four-stroke cycle or the two-stroke cycle. For details of working cycles see: Four-stroke cycle Two-stroke cycle Wankel engine Common cylinder arrangements are from 1 to 6 cylinders in-line or from 2 to 16 cylinders in V-formation. Flat engines – like a V design flattened out – are common in small airplanes and motorcycles and were a hallmark of Volkswagen automobiles into the 1990s. Flat 6s are still used in many modern Porsches, as well as Subarus. Many flat engines are air-cooled. Less common, but notable in vehicles designed for high speeds is the W formation, similar to having 2 V engines side by side. Alternatives include rotary and radial engines the latter have 7 or 9 cylinders in a single ring, or 10 or 14 cylinders in two rings. Petrol engines may be air-cooled, with fins; the coolant was water, but is now a mixture of water and either ethylene glycol or propylene glycol.
These mixtures have lower freezing points and higher boiling points than pure water and prevent corrosion, with modern antifreezes containing lubricants and other additives to protect water pump seals and bearings. The cooling system is slightly pressurized to further raise the boiling point of the coolant. Petrol engines use spark ignition and high voltage current for the spark may be provided by a magneto or an ignition coil. In modern car engines the ignition timing is managed by an electronic Engine Control Unit; the most common way of engine rating is what is known as the brake power, measured at the flywheel, given in kilowatts or horsepower. This is the actual mechanical power output of the engine in a complete form; the term "brake" comes from the use of a brake in a dynamometer test to load the engine. For accuracy, it is important to understand what is meant by complete. For example, for a car engine, apart from friction and thermodynamic losses inside the engine, power is absorbed by the water pump and radiator fan, thus reducing the power available at the flywheel to move the car along.

The United Kingdom the United Kingdom of Great Britain and Northern Ireland, sometimes referred to as Britain, is a sovereign country located off the north-western coast of the European mainland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, many smaller islands. Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state, the Republic of Ireland. Apart from this land border, the United Kingdom is surrounded by the Atlantic Ocean, with the North Sea to the east, the English Channel to the south and the Celtic Sea to the south-west, giving it the 12th-longest coastline in the world; the Irish Sea lies between Great Ireland. With an area of 242,500 square kilometres, the United Kingdom is the 78th-largest sovereign state in the world, it is the 22nd-most populous country, with an estimated 66.0 million inhabitants in 2017. The UK is constitutional monarchy; the current monarch is Queen Elizabeth II, who has reigned since 1952, making her the longest-serving current head of state.
The United Kingdom's capital and largest city is London, a global city and financial centre with an urban area population of 10.3 million. Other major urban areas in the UK include Greater Manchester, the West Midlands and West Yorkshire conurbations, Greater Glasgow and the Liverpool Built-up Area; the United Kingdom consists of four constituent countries: England, Scotland and Northern Ireland. Their capitals are London, Edinburgh and Belfast, respectively. Apart from England, the countries have their own devolved governments, each with varying powers, but such power is delegated by the Parliament of the United Kingdom, which may enact laws unilaterally altering or abolishing devolution; the nearby Isle of Man, Bailiwick of Guernsey and Bailiwick of Jersey are not part of the UK, being Crown dependencies with the British Government responsible for defence and international representation. The medieval conquest and subsequent annexation of Wales by the Kingdom of England, followed by the union between England and Scotland in 1707 to form the Kingdom of Great Britain, the union in 1801 of Great Britain with the Kingdom of Ireland created 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 and Northern Ireland. There are fourteen British Overseas Territories, the remnants of the British Empire which, at its height in the 1920s, encompassed a quarter of the world's land mass and was the largest empire in history. British influence can be observed in the language and political systems of many of its former colonies; the United Kingdom is a developed country and has the world's fifth-largest economy by nominal GDP and ninth-largest economy by purchasing power parity. It has a high-income economy and has a high Human Development Index rating, ranking 14th in the world, it was the world's first industrialised country and the world's foremost power during the 19th and early 20th centuries. The UK remains a great power, with considerable economic, military and political influence internationally, it is sixth in military expenditure in the world. It has been a permanent member of the United Nations Security Council since its first session in 1946.
It has been a leading member state of the European Union and its predecessor, the European Economic Community, since 1973. The United Kingdom is a member of the Commonwealth of Nations, the Council of Europe, the G7, the G20, NATO, the Organisation for Economic Co-operation and Development and the World Trade Organization; the 1707 Acts of Union declared that the kingdoms of England and Scotland were "United into One Kingdom by the Name of Great Britain". The term "United Kingdom" has been used as a description for the former kingdom of Great Britain, although its official name from 1707 to 1800 was "Great Britain"; the Acts of Union 1800 united the kingdom of Great Britain and the kingdom of Ireland in 1801, forming the United Kingdom of Great Britain and Ireland. Following the partition of Ireland and the independence of the Irish Free State in 1922, which left Northern Ireland as the only part of the island of Ireland within the United Kingdom, the name was changed to the "United Kingdom of Great Britain and Northern Ireland".
Although the United Kingdom is a sovereign country, Scotland and Northern Ireland are widely referred to as countries. The UK Prime Minister's website has used the phrase "countries within a country" to describe the United Kingdom; some statistical summaries, such as those for the twelve NUTS 1 regions of the United Kingdom refer to Scotland and Northern Ireland as "regions". Northern Ireland is referred to as a "province". With regard to Northern Ireland, the descriptive name used "can be controversial, with the choice revealing one's political preferences"; the term "Great Britain" conventionally refers to the island of Great Britain, or politically to England and Wales in combination. However, it is sometimes used as a loose synonym for the United Kingdom as a whole; the term "Britain" is used both as a synonym for Great Britain, as a synonym for the United Kingdom. Usage is mixed, with the BBC preferring to use Britain as shorthand only for Great Britain and the UK Government, while accepting that both terms refer to the United K
Iran Khodro, branded as IKCO, is an Iranian automaker headquartered in Tehran. The company's original name was Iran National. IKCO was founded in 1962 and it produced 688,000 passenger cars in 2009. IKCO manufactures vehicles, including Samand and Renault cars, trucks and buses; the word khodro means "automobile" in Persian, hence Iran Khodro means "Iran Automobile". Iran Khodro was founded by Ahmad Khayami, with registered in the capital of 100,000,000 Rls, on August 29, 1962 Aliakbar Khayami, Ahmad Khayami, Mahmoud Khayami, Marzieh Khayami and Zahra Seyedy Dashty, in Ekbatan world in Tehran. Iran Khodro Industrial Group is a public joint stock company with the objective of creation and management of factories to manufacture various types of vehicles and parts as well as selling and exporting them. IKCOOS produces vehicles under 13 brand names; the company has become the largest vehicle manufacturer in the Middle East, Central Asia and North Africa. In Iran, it is the largest vehicle manufacturing company, having an average share of 65 percent of domestic vehicle production.
In 1997, IKCO broke its own production record by producing 111,111 units of various passenger cars and vans. By 2006 Iran Khodro was producing 550,000 vehicles; the opening of the country's largest car assembly plant in Razavi Khorasan in July 2008 is expected to increase capacity with the ability to turn out 100,000 vehicles per year by late 2009.
