context_page_description: Circuit of the Americas is a grade 1 FIA-specification 3.426-mile motor racing track and facilities located within the extraterritorial jurisdiction of Austin, Texas. The facility is home to the Formula One United States Grand Prix, the IndyCar Classic, and the Motorcycle Grand Prix of the Americas, a round of the FIM Road Racing World Championship, as well a round of the Americas Rallycross Championship. It previously hosted the Australian V8 Supercars, the American Le Mans Series, the Rolex Sports Car Series, the FIA World Endurance Championship, and the IMSA WeatherTech SportsCar Championship.
  The circuit and Grand Prix were first proposed in the middle of 2010. The circuit was the first in the United States to be purpose-built for Formula One. The layout was conceived by promoter Tavo Hellmund and 1993 Motorcycle World Champion Kevin Schwantz with the assistance of German architect and circuit designer Hermann Tilke, who has also designed the Sepang, Shanghai, Yas Marina, Istanbul, Bahrain, Yeongam, and Buddh circuits, as well as the reprofiling of the Hockenheimring and Fuji Speedway. The circuit has an FIA Grade 1 license.
context_section_description: In an episode of Speed TV's Wind Tunnel program broadcast on August 22, 2010, Tavo Hellmund revealed that the circuit would be 3.4 miles (5.5 km) long and would be made up of twenty turns with an elevation change of 133 feet (41 m). The final plan of the circuit was released on September 1, 2010, showing a design inspired by the European tradition of sculpting the circuit to the contours of the land. The design draws from several European Formula One circuits, including a recreation of Silverstone's Maggotts–Becketts–Chapel sequence, Hockenheim's arena bends, and a replica of Istanbul's Turn Eight. Other corners were loosely inspired by the Senna 'S' at Interlagos and the Österreichring's Sebring-Auspuffkurve. A feature of the circuit is a deliberate widening of corners, to encourage drivers to follow multiple racing lines. A similar feature was used at the Buddh International Circuit in India, where the circuit widens on the approach to certain corners.
  The circuit was one of only a handful on the Formula One 2012 calendar to be run counter-clockwise, the others being Marina Bay, the Korea International Circuit, Yas Marina, and Interlagos. Because of this, the circuit contains more left-hand turns than right-hand ones, placing greater physical demands on the drivers whose bodies, particularly their necks, are more adapted to the lateral g-forces of clockwise circuits.
  From the start line, the drivers climb a gradient of over 11% to the first corner—the highest point of the circuit—with the apex of the corner positioned on the crest of the hill. They descend the hill to navigate a series of fast sweepers modeled on Silverstone's Maggotts–Becketts–Chapel complex and through a blind corner at Turn 10, taking them to the far end of the circuit and a hairpin at Turn 11. The drivers then follow a 0.62-mile (1.00 km) straight back towards the pit and paddock area before entering the final sector of the lap and weaving through a series of corners modeled on Hockenheim's stadium section. This is followed by a downhill, multi-apex corner with limited run-off before the final two corners of the circuit, a pair of left-hand bends that return the drivers to the main straight.
