An amateur spy videographer going by the name of Walko Art on YouTube recently spied a 2019 Mercedes-Benz C-Class Cabrio pre-production prototypes on the streets of Stuttgart.

On this particular prototype, engineers seem to be testing a multi-LED type of headlamp that we first saw on a C-Class Coupe facelift. The one thing that seems to be still in the mystery corner how the traditional LED “brows,” which act as both turning signals and daylight driving lights, will integrate with the multi-LED arrangement below in Mercedes' vision.


Apart from the new headlights and a couple of nips and tucks on the front and rear lights, the revamped C-Class will look mostly the same. The interior will get new materials for the upholstery and a slightly larger multimedia screen with slimmer bezels, along with a redesigned steering wheel.

The AMG-ified C43 model might be replaced by a C55 with 400+ horsepower squeezed out of a 3.0-liter inline-six paired with a 48-volt electrical system for extra go and better fuel economy. On the upper end of the lineup, the two C63 versions will get more power and a cylinder cut-off system like on the new E63 and S63. Both will remain RWD, though.
