With a Cd value of 0.22 and a frontal area of 2.19 m², the new Mercedes-Benz A-Class Sedan has the lowest drag of any production vehicle worldwide and thereby defends the original world record of the CLA Coupé. For three decades now, the aerodynamics engineers and designers at Mercedes-Benz have been repeatedly setting new records. The world record is currently held by the new A-Class Sedan with a Cd value of 0.22 and a drag of less than 0.49 m2. The good aerodynamic properties come from smooth surfaces and pure lines inspired by the Sensual Purity design philosophy and make a key contribution to low fuel consumption under everyday conditions.
In addition to the exterior shape, there are many small measures that led to the new record: a sophisticated reduction of the frontal area despite significantly improved interior comfort dimensions, an extensive sealing concept (such as the sealing of the headlamp surroundings) as well as almost complete panelling of the underbody, which includes the engine bay, main floorpan, parts of the rear axle and the diffuser. The front and rear wheel spoilers were optimised specifically to route the air around the wheels as efficiently as possible. The rims and tyres also underwent aerodynamic fine-tuning. Depending on the market, an optional two-part shutter system behind the radiator grille is available, which minimises the airflow through the engine bay.
