It looks like the 180 BlueEFFICIENCY model has a slightly lower drag coefficient then the other models. Does anyone know how they achieved this? I'm guessing part of it will be skinnier tires... but thats just a guess. Anyone else know?

Regular CLA 0.23 -- BlueEFFICIENCY 0.22!

The tires are indeed skinnier and a couple of other things compared to the normal 180:

-the rims are "aerodynamically designed" and made of steel
-the radiator has been partly covered
-the chassis is lower
+ a couple of smaller solutions beneath the car, for instance the rear axle has some extra shield/plastic to make it more aerodynamic
