Wow - .22 for the high efficiency model, coming later. Editing the post title.

From the PDF:

Aerodynamics have never looked better ... The result is a perfectly structured whole whose aerodynamics are unmatched in the series-production car sector.

Cd value of 0.23 (0.22 for CLA 180 BlueEFFICIENCY Edition expected to be available from 2nd quarter of 2013) is the lowest for any series-production vehicle
The impressive aerodynamic qualities of the new CLA ensure that it offers only slight air resistance, not just in the wind tunnel, but on the road, too. As a result, the expressive exterior design is accompanied by a Cd value of 0.23 – an outstanding achievement among series production vehicles and one which is second only to another model in the new CLA line-up: the CLA 180 BlueEFFICIENCY Edition (expected to be available from 2nd quarter of 2013) has a Cd value of just 0.22 thanks to the use of additional innovative technology.

How do you benefit from this? The optimised airflow around the vehicle plays a major role in achieving the measurable reduction in drag. The positive effects extend beyond a reduction in fuel consumption: low lift coefficients at the front and rear wheels make for agile handling, good driving stability at higher speeds and an assured response to crosswinds. The outstanding aerodynamics also make themselves felt inside the vehicle
where wind noise is reduced to a level unmatched in this category. All of which goes to show once again that, rather than being an end in themselves, good aerodynamic characteristics have lasting benefits in many different areas.
