Mercedes-Benz has released a new promotional clip for the CLA four-door coupe in which they demonstrate the vehicle's aerodynamic efficiency by using cats.

The marketing department over at Mercedes-Benz must have a soft spot for animals lately as after demonstrating the Magic Body Control system in the S-Class by using a chicken, now they rely on cats to show how aero efficient is the CLA. The new ad is simply called "Cat" and reminds us that we are dealing with the world's most aerodynamic efficient car as the baby Mercedes sedan has a Cd value of 0.22.

Not only does an aero efficient car improve fuel efficiency, but at the same time it also lowers noise and vibration levels so you get a more comfortable ride in a quieter cabin and you take fewer trips to the gas station. It should be mentioned the regular CLA has a drag coefficient of 0.23 and only the BlueEFFICIENCY variant is rated at 0.22.
