The CLE Coupe features a long wheelbase, a sharply angled A-pillar, a short front overhang and slightly longer rear overhang, pronounced shoulders and large wheel arches.

An extended wheelbase gives the coupe a roomier interior than the C-Class Coupe. It features an athletic profile with a forward-leaning, aero front end, a low-slung hood and flat LED headlights. An optional Digital Light system projects symbols onto the roadway to warn the driver in particularly challenging situations.
