Wind testing in race cars

Wind tunnel testing can also be useful when designing race cars.  Drag forces is something that can be analyzed in this kind of testing, and in the case of a race car, these analysis can help to design a faster car. Lift can be reduced in the car by changing the frontal area of it.  Wind testing can show how much drag force is acting on the car, therefore engineers can change the frontal part of the car to reduce these drag forces and make the race car faster and more efficient. This is one of the main reasons why the front part of a race car has a different structure than the front part of a regular car.
