Mercedes-Benz is sets a new milestone with the Mercedes-Benz CLA. With a cd value of 0.23 it is the most aerodynamic production car. This is pretty amazing. The Mercedes-Benz CLA 180 BlueEFFICIENCY Edition is even reaching a value of 0.22.
Better aerodynamics improve fuel efficiency and also reduce noise. Mercedes uses several innovations to achieve this great cd value. For example the CLA has a radiator featuring a shutter which only opens when the engine requires cooling.
To improve the flow of air under the vehicle there are extensive underbody panelling plus additional panelling in the middle area of the rear axle with an aerodynamically optimized rear silencer followed by a diffuser. Moreover, with special aerodynamic wheels and serrated wheel spoilers we managed to reduce the flow of air around the wheels appreciably. In addition, the dynamic rear end with spoiler lips on the boot lid and tail lights concentrates the flow behind the vehicle.
To make the point of this new achievement in aerodynamics, Mercedes-Benz released an entertaining new TV ad for the CLA featuring a cat. Watch the ad below.
