An eye-catching feature is the AMG rear skirt highlighting the black
diffuser. The openings emphasize the vehicle's width, as does the trim strip in
matte silver chrome - which reflects the design of the front skirt and frames
the AMG sports exhaust system. In contrast to the other M-Class variants, the
ML63 AMG features two sets of chrome twin tailpipes, providing that distinctive
AMG eight-cylinder sound.
