What is car aerodynamics and what does it affect?

Aerodynamics is the science of the motion of bodies in the air. In the context of a car, it studies how air flows around its body during movement. Good aerodynamics is not just a whim of designers, but the most important characteristic that directly affects the performance, safety and economy of the car. To make your vehicle more efficient and functional, you can use tuning accessories, a huge selection of which is available in our product catalog.

Drag coefficient: the main indicator

The main indicator of aerodynamics isthe drag coefficient (Cx or Cd). The lower this coefficient, the more streamlined the car body. For example, in modern passenger cars it is approximately 0.25–0.35. Reducing Cx by 10% can lead to fuel savings of up to 5% at high speed.

What does aerodynamics affect?

Good aerodynamics provide many advantages:

• Fuel economy : Reducing drag reduces fuel consumption by 5–10%.
• Stability : Improves stability at high speeds.
• Noise reduction : Streamlined shape reduces aerodynamic whistling.
• Dynamics : Increases acceleration efficiency and handling.

Elements that improve aerodynamics

• Spoilers and winglets : Create downforce, improving traction.
• Diffusers : Direct the airflow under the bottom, reducing turbulence.
• Streamlined mirrors and bumpers : Reduce air resistance.

Tips for drivers

• Avoid installing non-standard accessories that disrupt aerodynamics (for example, wide trunks).
• Regularly clean the body of dirt that increases resistance.
• For sports cars, choose tuning elements taking into account aerodynamic calculations.

Good aerodynamics make a car more economical, more stable and quieter, which is especially important for long trips and high speeds.
