Drag Coefficient

The drag coefficient quantifies how easily a vehicle moves through air. A lower Cd means less aerodynamic drag and better efficiency. Typical values range from 0.30-0.35 for sedans, 0.25-0.30 for sports cars, and as low as 0.20 for streamlined EVs like the Mercedes EQS. Formula 1 cars intentionally have high Cd (around 1.0) because they prioritize downforce over straight-line efficiency.
