When Mercedes officially announced the BlueEFFICIENCY line of C-Class luxury sedans the other day, the company only showed us one picture: this one. Soon after, we got a small handful of other images, all of them highlighting the BlueEFFICIENCY traits of better engines, improved aerodynamics and other fuel-saving measures. You can peep these shots in the gallery below, keeping in mind that Europeans will be able to purchase the most economical of the BlueEFFICIENCY C-Class models - the 46-mpg C 200 CDI - sometime this spring. For more details on the lineup, click here and check back for reports from Geneva.
