India
–
India, officially the Republic of India, is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and it is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west, China, Nepal, and Bhutan to the northeast, in the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. Indias Andaman and Nicobar Islands share a border with Thailand. The Indian subcontinent was home to the urban Indus Valley Civilisation of the 3rd millennium BCE, in the following millennium, the oldest scriptures associated with Hinduism began to be composed. Social stratification, based on caste, emerged in the first millennium BCE, early political consolidations took place under the Maurya and Gupta empires, the later peninsular Middle Kingdoms influenced cultures as far as southeast Asia. In the medieval era, Judaism, Zoroastrianism, Christianity, and Islam arrived, much of the north fell to the Delhi sultanate, the south was united under the Vijayanagara Empire. The economy expanded in the 17th century in the Mughal empire, in the mid-18th century, the subcontinent came under British East India Company rule, and in the mid-19th under British crown rule. A nationalist movement emerged in the late 19th century, which later, under Mahatma Gandhi, was noted for nonviolent resistance, in 2015, the Indian economy was the worlds seventh largest by nominal GDP and third largest by purchasing power parity. Following market-based economic reforms in 1991, India became one of the major economies and is considered a newly industrialised country. However, it continues to face the challenges of poverty, corruption, malnutrition, a nuclear weapons state and regional power, it has the third largest standing army in the world and ranks sixth in military expenditure among nations. India is a constitutional republic governed under a parliamentary system. It is a pluralistic, multilingual and multi-ethnic society and is home to a diversity of wildlife in a variety of protected habitats. The name India is derived from Indus, which originates from the Old Persian word Hindu, the latter term stems from the Sanskrit word Sindhu, which was the historical local appellation for the Indus River. The ancient Greeks referred to the Indians as Indoi, which translates as The people of the Indus, the geographical term Bharat, which is recognised by the Constitution of India as an official name for the country, is used by many Indian languages in its variations. Scholars believe it to be named after the Vedic tribe of Bharatas in the second millennium B. C. E and it is also traditionally associated with the rule of the legendary emperor Bharata. Gaṇarājya is the Sanskrit/Hindi term for republic dating back to the ancient times, hindustan is a Persian name for India dating back to the 3rd century B. C. E. It was introduced into India by the Mughals and widely used since then and its meaning varied, referring to a region that encompassed northern India and Pakistan or India in its entirety

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

City car
–
A city car is a small car designed to be used primarily in urban areas and conurbations. The term is used along with terms for small cars including subcompact in North America. The Euro NCAP calls all small cars superminis, the European Commission refers to A-segment. In Japan, the kei car is a type of small car. The original concept for the city car came about as a result of the market for entry level vehicles in the 1920s and 1930s. The great depression caused the market for large, luxurious vehicles to collapse, as a result, manufactures had no choice but to build small, cheap vehicles that people could afford, similar to early 20th century runabouts. However, these vehicles were not specifically branded as vehicles to use in cities or congested areas and they were purely for use as peoples cars, cars designed to be cheap, sell a large number of units, and put people who had not owned cars on wheels. A number of small, cheap cars were sold before the war, including the 1920s Austin 7, 1930s Fiat 500 Topolino. However, these early microcars werent true city cars, most were designed, built, with the exception of a few examples, these were also not designed for specific use in cities. As the European economy improved, Fiat launched the new 500 in 1957 and in 1959, BMC would introduce its well-known city car, there were other new projects from 1969 through 1972. While many of these cars can be considered city cars today, exceptions are the smaller Fiats, especially the 1957 Fiat 500 and 126. They were in the region of 3.0 metres in length, in the 1970s the Citroën LNA and related three-door Peugeot 104 offered compact city sized cars of around 3.3 m, and the Fiat Panda followed in 1980. In Japan, regulations defining kei cars were established on 8 July 1949, production of compliant vehicles started around 1955–1958 by Daihatsu, Mitsubishi, Subaru, and Suzuki. In the late 1980s, superminis had physically grown so much that many buyers wanted even smaller four-seat cars, combined with an original exterior and interior design, it quickly became a best-seller, although it was not officially imported to right-hand drive markets including the United Kingdom. However, the Fiat Cinquecento, launched towards the end of 1991, was made for right-hand drive markets, in 1996, the Ford Ka was presented with its radical New Edge design. Its egg-shaped body did not leave much room in the rear seats and it was especially popular with British buyers. During the second half of the 1990s, South Korean brands Daewoo and Hyundai introduced their city car entries, both for the Asian and European markets. The Hyundai Atos, launched in 1997, was 3,500 millimetres long and 1,600 millimetres high and its boxy shape provoked mixed reactions

A-segment
–
The A-segment is a car classification defined by the European Commission as the first segment in the European market car classification. It is a significant niche in Europe with 10. 4% market share in 2015, in recent years, the segment opened to premium cars with success, like the Mini and the Fiat 500. Vauxhall/Opel entered the segment with a model, the Adam. Vauxhall/Opel have had a presence in the A-segment since the launch of its Agila in 2000, the New York Times described the segment in 2012, saying today’s small cars actually span three main segments in the global vehicle market. A-segment cars are dominated by European models Mini and Fiat 500

Hatchback
–
A hatchback is a car body configuration with a rear door that swings upward to provide access to a cargo area. Hatchbacks may feature fold-down second row seating, where the interior can be reconfigured to prioritize passenger vs. cargo volume. Hatchbacks may feature two- or three-box design, while early examples of the body configuration can be traced to the 1930s, the Merriam-Webster dictionary dates the term itself to 1970. The hatchback body style has been marketed worldwide on cars ranging in size from superminis to small family cars, Hatchbacks may be described as three-door or five-door cars. A model range may include multiple configurations, as with the 2001–2007 Ford Focus which offered sedan, wagon, the models typically share a platform, drivetrain and bodywork forward of the A-pillar. Hatchbacks may have a rigid parcel shelf, liftable with the tailgate. Both station wagons and hatchbacks typically feature a two-box design configuration, with one shared, flexible, interior volume for passengers, further distinctions are highly variable, Pillars, Both configurations typically feature A, B & C pillars, station wagons more likely also feature a D pillar. Cargo volume, Station wagons prioritize passenger and cargo volume, with alongside the cargo volume. Cargo floor contour, Favoring cargo capacity, a station wagon may prioritize a fold-flat floor, seating, Station wagons have two or three rows of seats while hatchbacks have one or two rows of seats. Rear suspension, A station wagon may include reconfigured rear suspension for additional load capacity, Station wagons also have numerous tailgate configurations. Typically, a hatch or liftgate does not extend down to the bumper. You could have a 90-degree break in the back and have a station wagon, a liftback is a broad marketing term for a hatchback where the rear cargo door is more horizontal than vertical, with a sharply raked or fastback profile. In comparison with the hatchback the back opening area is sloped and longer and is lifted up to open. Liftback and fastback are often misused, a fastback is described as a hatchback where the rear cargo door flows down continuously from the roof of the car and most of the time is not as raked as the liftback. In 1946, DeSoto marketed the Suburban as a station wagon, in 1949, Kaiser-Frazer introduced the Vagabond and Traveler hatchbacks. Although these were styled much like the typical 1940s sedan, they incorporated an innovative split rear tailgate, folding rear seats, the design was neither fully a sedan nor a station wagon, but the folding rear seat provided for a large, 8-foot long interior cargo area. These Kaiser-Frazer models have described as America’s First Hatchback. In 1953, Aston Martin marketed the DB2 with a rear tailgate

Automobile layout
–
In automotive design, the automobile layout describes where on the vehicle the engine and drive wheels are found. Many different combinations of engine location and driven wheels are found in practice, factors influencing the design choice include cost, complexity, reliability, packaging, weight distribution, and the vehicles intended handling characteristics. Layouts can roughly be divided into two categories, front- or rear-wheel drive, four-wheel-drive vehicles may take on the characteristics of either, depending on how power is distributed to the wheels. Front-wheel-drive layouts are those in which the front wheels of the vehicle are driven, the most popular layout used in cars today is the front-engine, front-wheel drive, with the engine in front of the front axle, driving the front wheels. As the steered wheels are also the wheels, FF cars are generally considered superior to FR cars in conditions such as snow, mud. The weight of the engine over the wheels also improves grip in such conditions. Electronic traction control can avoid wheelspin but largely negates the benefit of extra torque/power, a transverse engine is commonly used in FF designs, in contrast to FR which uses a longitudinal engine. This is another reason luxury/sports cars avoid the FF layout, exceptions do exist, such as the Volvo S80 which uses transversely mounted inline 6 and V8 engines, and the Ford Taurus SHO, available with a 60° V8 and front-wheel drive. There are some exceptions to this as rear engine designs do not take away interior space and it also has fewer components overall and thus lower weight. However, this may apply for cars with moderate power-to-weight ratio. According to road test with two Dodge Daytonas, one FWD and one RWD, the layout is also important for what configuration is the fastest. Weight shifting limits the acceleration of a front-wheel-drive vehicle, however, since front-wheel-drive cars have the weight of the engine over the driving wheels, the problem only applies in extreme conditions in which case the car understeers. On snow, ice, and sand, rear-wheel drive loses its traction advantage to front or all-wheel-drive vehicles which have greater weight over the driven wheels. Rear-wheel-drive cars with engine or mid engine configuration retain traction over the driven wheels. A rear-wheel-drive cars centre of gravity is shifted rearward when heavily loaded with passengers or cargo, on front-wheel-drive cars, the short driveshaft may reduce drivetrain elasticity, improving responsiveness. Instead, the tunnel may be used to route the exhaust system pipes. Weight, Fewer components usually means lower weight, improved fuel efficiency due to less weight. Cost, Fewer material components and less installation complexity overall, however, the considerable MSRP differential between a FF and FR car cannot be attributed to layout alone. Few modern family cars have rear-wheel drive as of 2009, so a direct cost comparison is not necessarily possible, assembly efficiency, the powertrain can often be assembled and installed as a unit, which allows more efficient production

Front-engine, front-wheel-drive layout
–
In automotive design, an FWD, or front-engine, front-wheel-drive layout places both the internal combustion engine and driven roadwheels at the front of the vehicle. Historically, this designation was used regardless of whether the engine was behind the front axle line. Most pre-World War II front engine cars would qualify as front-mid engine, using the front-mid designation and this layout is the most traditional form, and remains a popular, practical design. The engine which takes up a deal of space is packaged in a location passengers. The main deficit is weight distribution — the heaviest component is at one end of the vehicle, car handling is not ideal, but usually predictable. Like the rear-engine, rear-wheel-drive layout and rear mid-engine, rear-wheel-drive layout layouts, it places the engine over the drive wheels, improving traction in many applications. As the steered wheels are also the wheels, FWD cars are generally considered superior to RWD cars in conditions where there is low traction such as snow, mud. When hill climbing in low traction conditions RR is considered the best two-wheel-drive layout, the cornering ability of a FWD vehicle is generally better, because the engine is placed over the steered wheels. However, as the wheels have the additional demands of steering, if a vehicle accelerates quickly, less grip is available for cornering. Electronic traction control can avoid wheel-spin but largely negates the benefit of extra power and this was a reason for the adoption of the four-wheel-drive quattro system in the high performance Jensen FF and Audi Quattro road cars. Early cars using the FWD layout include the 1929 Cord L-29,1931 DKW F1, the 1948 Citroën 2CV,1949 Saab 92, in the 1980s, the traction and packaging advantages of this layout caused many compact and mid-sized vehicle makers to adopt it in the US. Most European and Japanese manufacturers switched to front wheel drive for the majority of their cars in the 1960s and 1970s, the last to change being VW, Ford of Europe, Toyota was the last Japanese company to switch in the early 1980s. BMW, focussed on luxury vehicles, however retained the layout in even their smaller cars. There are four different arrangements for this layout, depending on the location of the engine. The earliest such arrangement was not technically FWD, but rather mid-engine, the engine was mounted longitudinally behind the wheels, with the transmission ahead of the engine and differential at the very front of the car. With the engine so far back, the distribution of such cars as the Cord L-29 was not ideal. The 1934 Citroën Traction Avant solved the weight issue by placing the transmission at the front of the car with the differential between it and the engine. Combined with the low slung unibody design, this resulted in handling which was remarkable for the era

Car platform
–
It is practiced in the automotive industry to reduce the costs associated with the development of products by basing those products on a smaller number of platforms. This further allows companies to create models from a design perspective on similar underpinnings. Platform sharing is a development method where different products and the brand attached share the same components. The purpose with platform sharing is to reduce the cost and have a more efficient product development process, the companies gain on reduced procurement cost by taking advantage of the commonality of the components. However, this limits their ability to differentiate the products. The companies have to make a trade-off between reducing their development costs and the degree of differentiation of the products, one of the first car companies to use this product development approach was General Motors in 1908. A basic definition of a platform in cars, from a point of view, includes, underbody and suspensions — where the underbody is made of front floor, underfloor, engine compartment. Many vendors refer to this as product or vehicle architecture, the concept of product architecture is the scheme by which the function of a product is allocated to physical components. The car platform strategy has become important in new product development, the finished products have to be responsive to market needs and to demonstrate distinctiveness while — at the same time — they must be developed and produced at low cost. Adopting such a strategy affects the development process and also has an important impact on an organizational structure. A platform strategy also offers advantages for the process of automobile firms. Manufacturers are then able to offer products at a lower cost to consumers, additionally, economies of scale are increased, as is return on investment. In the 1980s, Chryslers K-cars all wore a badge with the letter K to indicate their shared platform, in later stages, the K platform was extended in wheelbase, as well as use for several of the Corporations different models. GM used similar strategies with its J platform that debuted in mid-1981 in four of GMs divisions and they were popular through the 1980s, primarily. Even Cadillac started offering a J body model called the Cimarron, a similar strategy applied to what is known as the N-J-L platform, arguably the most prolific of GMs efforts on one platform. Once more, GMs four lower level divisions all offered various models on this throughout the 1980s. For example, the Lexus ES is essentially an upgraded and rebadged Toyota Camry, after Daimler-Benz purchased Chrysler, Chrysler engineers used several M-B platforms for new models including the Crossfire which was based on the M-B SLK roadster. Other models that share platforms are the European Ford Focus, Mazda 3, differences between shared models typically involve styling, including headlights, tail lights, and front and rear fascias
