Explain the concept of drag coefficient in automotive design.

• The drag coefficient measures a vehicle's weight distribution.

• The drag coefficient is a measure of tire friction on the road.

• The drag coefficient is only relevant for electric vehicles.

• The drag coefficient is a measure of a vehicle's aerodynamic efficiency, influencing fuel consumption and performance.

What role does airflow play in vehicle stability at high speeds?

• Airflow only affects fuel efficiency, not stability.

• Airflow has no effect on vehicle stability at any speed.

• Airflow increases drag, making vehicles less stable.

• Airflow stabilizes vehicles at high speeds by generating downforce and enhancing tire traction.
