«We found that the Brazuca ball had
more aerodynamic resistance at wind speeds between 50 and 70 km / h, compared with the Jabulani ball.
Aerodynamic blades feature on the outer edges of the rear window, and the floating rear wing, integrated rear spoiler and spoiler lip
reduce aerodynamic resistance.
Mercedes - Benz also claims that the frontal surface area, Cd x A — which is crucial to
aerodynamic resistance — also leads the field at 5.49 sq. ft.
The drag area, Cd x A - which is crucial to
aerodynamic resistance — also leads the field, at 0.51 m ².
This approach includes reducing work the engine must perform — reducing vehicle weight,
aerodynamic resistance, rolling resistance, and accessories — plus improving the efficiency of the internal combustion engine powertrain.
