The Chinese Grand Prix
is a round of the Formula One World Championship. It is currently held at the Shanghai International Circuit, Jiading, Shanghai, designed by Hermann Tilke. When completed in 2004, it was the most expensive Formula One circuit facility, costing US$240 million. Abu Dhabi became the most expensive at US$6 billion when it opened in 2009. The track is 5.451 km long and features one of the trickiest corners combinations on the Formula One calendar, comparable to that of Istanbul Park's turn 8, also designed by Tilke. Turn 1 and 2 are a very demanding 270-degree, right-handed corner combination that requires considerable speed, in addition to a significant radius increase as the corner progresses.
