When the Mercedes-AMG GT first burst into the scene a few years ago, many thought that the model would merely be a successor to the highly popular SLS AMG. It wasn’t as powerful as the SLS, but the GT did have plenty of similarities to its predecessor. Over time though, the GT became less of a stand-alone performance car as Mercedes-AMG decided to use it as a springboard to launch a family of performance cars. And so here we are, recently removed from seeing the debut of the AMG GT C Coupe at the 2017 North American International Auto Show. Not only is the GT C Coupe’s debut significant in that it becomes the sixth variant of the GT family, but just as important is Mercedes using the same occasion to announce cosmetic and engine updates on the entire range of GT models.
