The BlueEFFICIENCY badge has been showing up on many of our 2012 models and it has generated a lot of interest. In general, BlueEFFICIENCY is anything that Mercedes-Benz does to be more fuel efficient or environmentlly friendly. The diesel vehicles have been badged this way for a few years and many of the 2012 models earned the badge as a result of the new direct injected engines.
In short – Blue is the new Green!
