Our spies have managed to catch the 2014 Mercedes C-Class undergoing testing.

Caught heavily disguised, the model appears to have an evolutionary design with a smaller grille and slimmer headlights. While it's hard to judge the car's size, speculation has suggested it will be taller and wider than the current model.

Engine options remained unconfirmed, but we can expect a variety of four-cylinders will be available. There could also be a be a three-cylinder engine as well as a hybrid variant.
