The Mercedes-Benz EQS launched with a claimed drag coefficient of 0.20, making it one of the most aerodynamically efficient production cars at the time. The EQS is a large luxury electric liftback introduced by Mercedes-Benz in 2021.
Drag coefficient is a dimensionless measure of aerodynamic resistance. It is not the same as the total force acting on a car, because frontal area and speed also matter. A low coefficient helps reduce energy consumption, especially during steady high-speed driving, which can improve an electric vehicle’s highway range.
The EQS achieved its figure through a smooth underbody, carefully shaped bodywork, flush door handles, and other airflow details. Real-world efficiency still depends on wheels, tyres, weather, speed, and equipment. The figure is therefore a laboratory-style vehicle specification rather than a guarantee of identical range for every EQS version.
