In the mean time, for 2009, the CLS gets revised front and rear, a new grille, larger outside mirrors, and LEDs in the tail-lamp clusters. Inside, a new steering wheel complements the reworked interior and a next-generation COMAND system.

The 2010 Mercedes-Benz CLS is undergoing testing, and as is true with so many segment-defining vehicles, there doesn't look to be much of a change going on up top. However, down below, in the area covered by cladding, we will probably see some noticeable tweaks and refinements as the original "four-door coupe" moves from the current E-Class to the new E-Class platform (it will not be built on the S-Class platform). As for engines, in addition to gas and (in Europe) diesel options, it will be offered with the BlueHybrid drivetrain from the S400.
