The 2013 Mercedes-Benz S-Class has a drag coefficient of 0.24. This means that it has a very low resistance to air, which helps it to be more fuel-efficient and to have a higher top speed. The drag coefficient of a car is measured by the amount of air resistance that the car experiences when it is moving through the air. The lower the drag coefficient, the less resistance the car experiences, and the more fuel-efficient it is.
