I've noticed that some BMW 4 Series models have a convertible attached to the side of the car. What is the purpose of this feature and how does it benefit the driver?
ReplyThe convertible attached to the side of the car is called the Air Curtain. It is designed to improve aerodynamic performance and reduce drag while driving at high speeds.
Not only does the Air Curtain improve aerodynamics, but it also helps to reduce wind noise in the car for a more comfortable ride.
In addition, the Air Curtain can help to improve fuel efficiency by reducing the amount of air resistance while driving.
