Mercedes-Benz has announced that its upcoming A-Class sedan will be the most aerodynamic car on sale. The company claims that the new A-Class sedan has a coefficient of drag (Cd) 0.22 and a front area of 2.19 square meters. Mercedes-Benz says the new A-Class sedan's class-leading aerodynamic properties can be attributed to the effort gone into refining the shape of the car. The designers spent countless hours in the wind tunnel while the use of virtual modelling techniques gave further insight into developing an optimal aerodynamic shape.

From the above they did a lot of work where you just don't see it.

The new A-Class Saloon takes advantage of the favourable conditions provided by its long rear end to undercut even the already exemplary A-Class with hatchback (Cd value from 0.25). With a benchmark of Cd = 0.22 the new saloon model even equals the original world record of the CLA Coupé. Thanks to the frontal area of 2,19 m², smaller than that of the CLA, the new A-Class Saloon has the lowest aerodynamic drag of all production vehicles worldwide.

Great numbers, but far from theoretical idea.
