The track, designed by architect Hermann Tilke, winds through the picturesque streets of Baku. The endless straightaway (2 km) that leads back to the start permits the cars to reach very fast speeds. In general, the entire track is run with the pedal to the floor, which is demonstrated by the fact that the wide open throttle time is equivalent to 56% of the race.
In fact, last year Nico Rosberg managed to complete a lap going an average speed of more than 210 km/h. The circuit also has a lot of technical corners, like turns 8 and 15, where precision braking is key to avoiding contact with the walls, which are extremely close at these points.
The layout includes four 90° corners at the start that demand great effort on the part of the brakes, followed by other turns where the angels change continuously and as a consequence so does the use of brakes.
According to Brembo technicians, who classified the 20 tracks in the World Championship on a scale of 1 to 10, the Baku City Circuit is demanding on the brakes.
The Azeri track earned an 8 on the difficulty index, which is just what nearby Sochi and three other tracks got, including Monza.
