Da Nang

Đà Nẵng ( listen) is one of the major port cities in Vietnam (in addition to Ho Chi Minh City and Hai Phong) and the biggest city on the Central Vietnam; the city is situated on the coast of the Eastern Sea, at the opening end of the Hàn River. Đà Nẵng is the commercial and educational center of Central Vietnam, with a well-sheltered, easily accessible port; its location on the path of National Route 1A and the North–South Railway makes it a hub for transportation. It is located within 100 km of several UNESCO World Heritage Sites, including the Imperial City of Huế, the Old Town of Hội An, and the Mỹ Sơn ruins. The city was previously known as Cửa Hàn during early Đại Việt settlement, and as Tourane (or Turon) during French colonial rule. It is the third biggest economic center in Vietnam (after Ho Chi Minh City and Hanoi).

Before 1997, the city was part of Quảng Nam-Đà Nẵng Province. On 1 January 1997, Đà Nẵng was separated from Quảng Nam Province to become one of five independent (centrally controlled) municipalities in Vietnam. Đà Nẵng is listed as a first class city, and has a higher urbanization ratio than any of Vietnam's other provinces or centrally governed cities. In terms of urban population, Đà Nẵng is the fifth largest city in Vietnam.

Vietnam (UK /ˌvjɛtˈnæm, -ˈnɑːm/, US ⁱ/ˌviːətˈnɑːm, -ˈnæm/;Vietnamese: Việt Nam [viət˨ næm˧]), officially the Socialist Republic of Vietnam (SRV; Vietnamese: Cộng Hòa Xã Hội Chủ Nghĩa Việt Nam ( listen)), is the easternmost country on the Indochina Peninsula in Southeast Asia. With an estimated 90.5 million inhabitants as of 2014, it is the world's 14th-most-populous country, and the eighth-most-populous Asian country. The name Vietnam translates as "Southern Viet" (synonymous with the much older term Nam Viet); it was first officially adopted in 1802 by Emperor Gia Long, and was adopted again in 1945 with the founding of the Democratic Republic of Vietnam under Ho Chi Minh. The country is bordered by China to the north, Laos to the northwest, Cambodia to the southwest, and Malaysia across the South China Sea to the southeast. Its capital city has been Hanoi since the reunification of North and South Vietnam in 1975.

Group C

Group C was a category of motorsport, introduced by the FIA in 1982 for sports car racing, along with Group A for touring cars and Group B for GTs.

It was designed to replace both Group 5 Special Production Cars (closed top touring prototypes like Porsche 935) and Group 6 Two Seater Racing Cars (open-top sportscar prototypes like Porsche 936). Group C was used in the FIA's World Endurance Championship (1982–1985), World Sports-Prototype Championship (1986–1990), World Sportscar Championship (1991–1992) and in the European Endurance Championship (1983 only). It was also used for other sports car racing series around the globe. The final year for the class came in 1993. Broadly similar rules were used in the North American IMSA Grand Touring Prototype series GTP.

History

The roots of the Group C category lie in both FIA Group 6 and particularly in the GTP category introduced by the ACO at Le Mans in the mid-1970s. GTP was a class for roofed prototypes with certain dimensional restrictions, but instead of the more usual limits on engine capacity, it placed limits on fuel consumption. The FIA applied the same concept in its Group C rules. It limited cars to a minimum weight of 800 kg and a maximum fuel capacity of 100 litres. With competitors restricted to five refueling stops within a 1000 kilometer distance, the cars were effectively allowed 600 litres per 1000 kilometers. The FIA hoped this would prevent manufacturers from concentrating solely on engine development; in the late 1970s, a few manufacturers (especially Porsche and Lancia) had dominated sports car racing by simply increasing turbocharger boost pressure, especially in qualifying trim — the 3.2 L Porsche 935 was capable of more than 800 hp. Engines had to be from a recognized manufacturer which had cars homologated in the FIA's Group A Touring Car or Group B GT Car categories.

Asia

Asia (ⁱ/ˈeɪʒə/ or /ˈeɪʃə/) is the Earth's largest and most populous continent, located primarily in the eastern and northern hemispheres. Asia covers an area of 44,579,000 square kilometers, about 30% of Earth's total land area and 8.7% of the Earth's total surface area. It has historically been home to the world's first modern civilizations and has always hosted the bulk of the planet's human population. Asia is notable for not only overall large size and population, but unusually dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people. The boundaries of Asia are traditionally determined as that of Eurasia, as there is no significant geographical separation between Asia and Europe. The most commonly accepted boundaries place Asia to the east of the Suez Canal, the Ural River, and the Ural Mountains, and south of the Caucasus Mountains and the Caspian and Black Seas. It is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean and on the north by the Arctic Ocean.
