While he was out capturing photos of the future Mercedes-Benz Gullwing, our friend Rich of Automotive Traveler also managed to grab a few shots of what we would surmise to be the 2010 Mercedes-Benz S63 AMG and CL63 AMG testing in the California desert.  As evidenced by the heavy masking in the S63 AMG photo, a revised front apron is unquestionably in the works for the model – an exterior enhancement that, when paired with the new front grille, will likely be the most notable change to the 2010 variant.  Although not visible in the photos, a new front apron will likely make its way onto the 2010 AMG-powered C-Class models as well.

Aside from the front apron, changes to the next AMG S-Class variants will mimic those of the standard 2010 S-Class.  Slightly revised headlights and taillights are planned (despite the fact that in the photos, both appear to the same as the ones found on the current model), while there will likely be the requisite interior and electronics tweaks to make the impeccable models even more appealing. 

We will of course keep you posted as new details of both the AMG-powered S-Class and CL-Class models emerge; in the meantime, keep scrolling to see a few additional shots of both, then head over to Automotive Traveler where you can find the high resolution S-Class and CL-Class spy photo galleries in their full, unadulterated glory.

Enjoy.
