Note: Typical frontal areas: sedan 22-24 ft², SUV 28-34 ft², sports car 18-21 ft². The Cd×A product is the key metric for comparing vehicles of different sizes. Lower Cd×A means less aerodynamic drag.

Reference

Frontal Area ≈ 0.80 × Width × Height (shape factor) Cd×A = Drag Coefficient × Frontal Area Drag Force = ½ × ρ × V² × Cd × A ρ = 0.00238 slug/ft³ (sea level standard) Drag scales with V² (speed squared)
