<P> The Circuit of Americas in Austin, the Sochi Autodrom in Sochi and the Baku City Circuit in Azerbaijan have all been introduced as brand new tracks since 2012 . </P> <P> A single race requires hotel rooms to accommodate at least 5000 visitors . </P> <P> Modern Formula One cars are mid-engined, hybrid, open cockpit, open wheel single - seaters . The chassis is made largely of carbon - fibre composites, rendering it light but extremely stiff and strong . The whole car, including engine, fluids and driver, weighs only 691 kg (1,523 lb)--the minimum weight set by the regulations . If the construction of the car is lighter than the minimum, it can be ballasted up to add the necessary weight . The race teams take advantage of this by placing this ballast at the extreme bottom of the chassis, thereby locating the centre of gravity as low as possible in order to improve handling and weight transfer . </P> <P> The cornering speed of Formula One cars is largely determined by the aerodynamic downforce that they generate, which pushes the car down onto the track . This is provided by "wings" mounted at the front and rear of the vehicle, and by ground effect created by low air pressure under the flat bottom of the car . The aerodynamic design of the cars is very heavily constrained to limit performance and the current generation of cars sport a large number of small winglets, "barge boards", and turning vanes designed to closely control the flow of the air over, under, and around the car . </P>
