Abstract
Aerodynamic drag is one of the main obstacles to accelerate a solid body when it moves in the air. About 50 to 60% of total fuel energy is lost only to overcome this adverse aerodynamic force. To win a race, which may be decided by fraction of second, the racing cars need a faster acceleration, which is possible by reducing the drag force by optimizing its shape to ensure stream-lining or reducing the separation. By adding vortex generators on the roof and extending the rear body of the car aerodynamically which could reduce the drag of the vehicle by 25% which further improves the fuel efficiency of the vehicle. The amount of grip available in the tires along with aerodynamic drag and engine power set the theoretical limits for the vehicle's velocity around the track, especially in cornering
