The Circuit de Barcelona-Catalunya ((:sirˈkujd də kətəˈɫuɲə)) is a motorsport race track in Montmeló, Barcelona, Catalonia, Spain. With long straights and a variety of corners, the Circuit de Barcelona-Catalunya is seen as an all-rounder circuit. The track has stands with a capacity of 140,700.〔http://www.worldstadiums.com/europe/countries/spain/catalonia.shtml〕 The circuit has FIA Grade 1 license. Until 2013 the track was known only as the ''Circuit de Catalunya'', before a sponsorship deal with Barcelona City Council added Barcelona to the track's title. ==History== The Circuit de Barcelona-Catalunya was built in 1991 and began hosting the Spanish Grand Prix that same year. Construction also coincided with the Olympic Games scheduled to take place in Barcelona the next year, where the circuit acted as the start and finish line for the road team time trial cycling event.〔(1992 Summer Olympics official report. ) Volume 2. pp. 305–7.〕 The Circuit de Barcelona-Catalunya should not be confused with the Montjuïc circuit, which hosted the Spanish Grand Prix four times between 1969 and 1975 and, unlike the Circuit de Barcelona-Catalunya, is actually located within the city of Barcelona. Because so much testing is done at this circuit, Formula One drivers and mechanics are extremely familiar with it. This has led to criticism that drivers and mechanics are too familiar with Catalunya, reducing the amount of on-track action. When first used, overtaking was frequent as cars could follow closely through the last two corners and slipstream down the long straight. As aerodynamic balance became more critical, this overtaking method drastically decreased as the cars were unable to follow each other through the fast final corner due to turbulence created by the leading car.〔 The 2007 season saw the first of the two final sweepers replaced with a slow chicane in an effort to improve overtaking. However, the redesign has not yet shown any effect.〔 The Circuit de Barcelona-Catalunya also plays host to many other racing series, including MotoGP. The chicane which was put in the penultimate turn for Formula 1 does not play a part in the track layout for Moto GP, and there are at least five points on the track (turns 1, 2, 4, 10, 14) where riders are known to overtake. As in Formula 1, turn one is arguably the most popular place for overtaking. The circuit is not known to produce copious amounts of overtaking, despite the long straights. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Circuit de Barcelona-Catalunya」の詳細全文を読む スポンサード リンク
