F1 car is completely different from cars that we see on roads. It is streamlined in shape with a long sharp nose at the front of the car. The front wing which is composed of layers of sharp flat blades is attached to the front end of the nose. At the end of the nose, the cockpit is positioned. Behind that engine & gearbox components are positioned. It is totally covered with the engine cover to maintain the smooth air flows over the car. Finally, the rear wing is positioned with a moving blade to support the DRS. The underside of the car is totally covered with the ‘floor’ to maintain the smooth airflows.
