A camouflaged prototype of the Mercedes-Benz C-Class Coupe (C205) has been spied in Stuttgart, Germany.

Design chief Gorden Wagener is promising the new C-Class Coupe will be more beautiful than the S-Class Coupe and that it's going to be "even better to drive than it looks." Seen here is a fully camouflaged prototype of the model carrying a roof box in the busy traffic of Stuttgart where the vehicle was undergoing testing ahead of an expected reveal in September at the Frankfurt Motor Show.

Wagener previously said the C-Class Coupe will be the "coolest version" of the W205 generation and will obviously ride on the same MRA platform as the sedan and wagon. It will get the same array of turbocharged gasoline and diesel engines, including the twin-turbo V6 3.0-liter unit with 367 PS (270 kW) and 517 Nm (382 lb-ft) which will power the AMG Sport version.

The most appealing version of the range will obviously be the Mercedes-AMG C63 Coupe set to receive a twin-turbo V8 4.0-liter engine unleashing 476 PS (350 kW) and 650 Nm (479 lb-ft) in the standard model and 510 PS (375 kW) and 700 Nm (516 lb-ft) in the S version. You will have to wait a little bit more for the fully-fledged AMG models as these are expected to come out by mid-2016.

Details and images with the standard C-Class Coupe should hit the web around August before the Frankfurt official debut.
