Bricks in the Wind: Ten Cars With the Worst Aerodynamics

This piece catalogs ten cars noted for notably poor aerodynamics, listing their drag coefficients (0.4–1.05 Cd) and explaining how design choices—ranging from early brick-like shapes to modern high-downforce track cars—made them wind-inefficient. Examples span the Ford Model T (0.79 Cd) and Mercedes Simplex (1.05 Cd) to the Plymouth Prowler (0.49 Cd), Citroën 2CV (0.52 Cd), VW Beetle variants (0.48–0.40 Cd), Dodge Viper ACR (0.541 Cd), Caterham Seven (0.60 Cd), and others, noting data limits and exclusions (no SUVs/trucks) and highlighting aero evolution toward contemporary efficiency.
