The 2005 Formula One calendar featured a new event in Turkey, just miles from the Europe-Asia dividing line. The newly-built circuit in Istanbul joined the 2004 newcomers Bahrain and China. The 2005 season witnessed two of the hottest grands prix ever: the track temperature at the beginning of the Malaysian event was 51 °C (124 °F), while in Bahrain the mercury soared past 56 °C (133 °F).
