Turkey made its debut on the Formula One calendar in 2005 with an all-new purpose-built circuit in Istanbul. The spectacular 5.378 kilometre track is designed by famed German architect Hermann Tilke, the man behind Sepang, Bahrain and Shanghai, and features 14 turns - eight lefts and six rights - with the cars reaching speeds of up to 330 km/h.

An unusual feature of the venue is that the lap runs anti-clockwise, making the Turkish Grand Prix only the third race on the calendar to do so (San Marino and Brazil are the other two). It possesses a wide variety of corners, and while perhaps not as technical as, say, Shanghai, it definitely provides the drivers with real challenge, especially given the reduced downforce available from 2005.

The character of the circuit is further enhanced by plenty of gradients - the track is built on four different ground levels. There may be fewer obvious overtaking opportunities than at some other Tilke circuits - it doesn't feature the long straights followed by tight hairpins that characterise the likes of Sepang and Shanghai - but the potential for a driver under pressure to make a mistake here means no shortage of passing.

As you'd expect from a new venue, spectator facilities are impressive - organisers knew they had to rival the very high standards set by Bahrain and China in 2004. Seating capacity is around 130,000, with 25,000 of those in the main grandstand, and parking is available for 12,000 cars. Dominating the circuit's skyline are two seven-floor VIP towers at either end of the paddock.
