It would be safe to assume that since it would be based on the sedan, some features from that 4-door model would make it to the coupe. Based on the spy photographs we have seen, the future C-Class coupe will carry over the sedan’s front section, including the taillights and the rear bumper. As expected, there will be new rooflines, doors and windows.
It is possible that Mercedes will offer the new C-Class at a price lower than that of the sedan, in consideration of the decrease in the purchasing power of the consumer these past years.
As for the motive power for these coupes, it is anyone’s guess but existing powerplant configurations for the sedan come from four and six cylinder engines delivering 155 to 290 horsepower. Mercedes-Benz also has diesels of up to 230 horsepower for the sedan but only they know if those oil burners will make it to the coupe.
