The German car maker has uses its patterned disguise tape to suggest the presence of a door pillar, though the C-Class Coupe is expected to feature a pillar-less profile like the S-Class Coupe.

The AMG C63 Coupe will feature a wider track and lower ride height, we know; it remains to be seen whether such a change is applied to the regular models.
Inside, the Coupe will largely share its presentation with the sedan's cabin - which is no bad thing considering the C-Class currently offers the benchmark interior for quality and design.
Engines will also be familiar from the C-Class sedan family, meaning turbocharged four-cylinder petrols and diesels, twin-turbo V6s and the AMG's twin-turbo V8.

The Mercedes-Benz C-Class Coupe is likely to make its public debut at September's Frankfurt motor show. It's due to go on sale in Australia in early 2016.
