There are more changes than meets the eye compared to the coupe.

The last time we spotted Mercedes-AMG’s GT-based roadster it was being benchmarked against a Porsche 911 Cabriolet on the German autobahn. Now, the model has been photographed once again in Germany, but this time it was among more humble cars. While the design will be largely carried over from the coupe, there are some changes, besides the obvious switch to an electrically-retractable soft top.

In order to accommodate the roof while it’s folded, the trunk lid has been reshaped and is now considerably wider. While on the coupe the third brake light sits up high on the rear window, on the roadster it will be integrated in the trunk lid. Interestingly, we also notice there is a horizontal slat between the taillights which the standard and S versions of the coupe don’t have. That being said, the recently introduced R model has that opening in the rear bumper, so maybe we are looking at a new variant of the car that will slot between the S and the R.

Updated Mercedes-Benz 2017 roadmap

As a matter of fact, the 2017 roadmap published just a few days ago by Mercedes revealed the open-top’s full name will be “GT C Roadster” and also it showed an equivalent “C” coupe. The beefy R version has an extra 74 horsepower and 37 pound-feet of torque and is 199 lbs (90 kg) lighter than the S, so perhaps Mercedes-AMG is thinking there is room for a “C” model to bridge the gap between the two.

We will know that for sure next year when the GT C will come out in both coupe and roadster flavors. According to the aforementioned roadmap, the roadster will actually be the first to come out and will be followed months later by the coupe.
