Om Shanghai International Circuit:
The Shanghai International Circuit (simplified Chinese: ???????; traditional Chinese: ???????; pinyin: Shàngh?i Guójì Sàich?ch?ng) is a motorsport race track, situated in the Jiading, Shanghai, People's Republic of China. The circuit is best known as the venue for the annual Formula 1 Chinese Grand Prix, which it first hosted in 2004.
Costing approximately 2.6 billion yuan ($450 million), the circuit was financed by a government-funded joint-venture company, consisting of the Shanghai Juss Corporation, Shanghai National Property Management Co Ltd, and Shanghai Jia'an Investment and Development Co Ltd. Architectural and design experts began planning and visiting the site between April and May 2003, and the area was transformed from swampland to international racetrack within 18 months with a team of 3000 engineers working around the clock.
Other events held at the circuit include a round of the MotoGP world championship, the Australian-based V8 Supercar championship in 2005, attracting crowds of over 250,000 spectators, and also the final round of the A1 Grand Prix in 2006/2007.
The 2008 MotoGP race was the last one on this circuit, as the FIM didn't select the racetrack for the provisional calendar of 2009. This is due to overcrowding problems in the circuit.
In September 2007, former manager of the circuit Yu Zhifei  was convicted of embezzlement as part of a corruption scandal in Shanghai which resulted in the dismissal of several senior Chinese Communist Party officials.
Partly due to location of the circuit, areas around turns 1, 8 and 14 have been sinking, and therefore the circuit had to be inspected before the 2011 event took place.
The Chinese Grand Prix attracted 260,000 spectators in its inaugural year in 2004 with a slight 10,000 increase in 2005, but attendance has since declined with 155,000 attending in 2010. On Feb 18, 2011, Reuters reported words from the Chinese Grand Prix organizers said Shanghai has extended the deal to host the Chinese Grand Prix to 2018 despite falling attendance. Reuters reported words from Yiping Chen, deputy director of the Shanghai Sports Bureau, suggested the situation can improve in the following years by lowering the ticket cost. Reuters reported prices for prime seats range would decrease from 3,580-3,980 yuan in 2010 to 1,980-3,280 yuan in 2011. On the same day, AFP reported that the Shanghai City government will keep open a subway line to the race track to boost spectator numbers from April 1517, 2011.
The Feb 18, 2011 Reuters news also reported words from Wen Zhao, vice-mayor of Shanghai, suggested F1 is a calling card for Shanghai and she is confident that the success of the event in the years ahead.
In common with many other new Formula One circuits, it was designed by Hermann Tilke, and also features his trademark track feature: a long back straight followed by a hairpin turn. Current-generation F1 cars can easily surpass 300 km/h (186 mph) on the long straight between corners 13 and 14. The track layout was inspired from the Chinese character shang (?) the first character in the name of the city Shanghai, meaning "above" or "ascend". One lap lasts 5.5 kilometres (3.4 mi). The whole circuit plus seating areas and other areas for spectators, covers a total area of 5.3 km².
A lap in a Formula One car
Turns 1 and 2 make up a very long right-hand curve which leads immediately into turns 3 and 4, a very long left-hand curve. One and two are far more difficult - a lift on entry followed by various taps of the throttle and brakes are needed so the car maintains balance throughout. It also becomes blind towards the middle of the corner. Three and four are nowhere near as difficult but a good exit is needed to gain speed down the following straight and through turn 5. Turn 6 is a second gear, right-handed hairpin with plentiful run-off. Turns 7 and 8 make up a high speed chicane - the left-right complex sees a constant G-force of 3 and a minimum speed of about 100 mph. Turns 9 and 10 immediately follow - two slow left-handers which require a good exit to gain speed down the next straight. Turns 11 and 12 effectively make up a slow left-right chicane where the use of kerbs are important but traction is low. Turn 13 is a very long right-hander which becomes less and less tight, and a very good exit is important as the longest straight in F1 follows. It is the equivalent to 11 football pitches laid end to end, or the same length as three and a half of the world's biggest aircraft carriers Turn 14 is a hairpin at the end of the straight - the second gear corner is a prime overtaking spot as DRS is available in the run up to the corner. Turn 16 is the last corner - a fourth-gear left-hander which requires a quick tap on the brakes - braking early can be more effective as you can then carry more speed through the corner and then down the pit straight.
The total length of the circuit is 5.451 km (3.387 mi), which is about average for a Formula One circuit. The lap record was set by Ferrari's Michael Schumacher in 2004. He completed one lap of the circuit in 1:32.238. Källa: Wikipedia.
