Question

Which of the following is not a reason for fitting spoilers on cars?

• A. To increase drag coefficient
• B. It provides better airflow over and around the car
• C. To decrease the drag coefficient
• D. To reduce the lift of the car

Answer 1

The correct option is A

To increase drag coefficient

Spoilers are added to counter the lift of the car without having to increase the weight of the car. The main reason people install spoilers is to allow for better airflow over and around the car, which in turn creates a better grip on the road. This reduces the drag coefficient, which is a measure to quantify the drag or resistance of an object in a fluid environment, such as air or water.
