What is the drag coefficient of the Mercedes-Benz C-Class?
1 Answers
The drag coefficient of the Mercedes-Benz C-Class is 0.24. Drag Coefficient: The air resistance coefficient, also known as the drag coefficient, is an important factor in calculating the air resistance of a car. Air resistance is the largest and most significant external force encountered by a vehicle during motion. Determined through wind tunnel tests and coast-down experiments, this mathematical parameter helps calculate the air resistance a car faces while driving. The magnitude of the drag coefficient depends on the car's shape—the higher the coefficient, the greater the air resistance. Modern cars typically have drag coefficients ranging between 0.2 and 0.5. Impact of Drag Coefficient: Generally, a car with a low drag coefficient will have an aesthetically pleasing design and improved fuel efficiency. Features like a downward-sloping front end, floating roof design, and hidden door handles are all aimed at achieving a lower drag coefficient. Additionally, when a car reaches speeds of 80 km/h, 50%-60% of the engine's output power is consumed in overcoming air resistance. Reducing the drag coefficient can significantly improve fuel efficiency.
