2019 Mercedes-AMG GT 'Black Series' spied

A development prototype believed to be the upcoming Mercedes-AMG GT Black Series has been snapped this week, further fuelling rumours the German performance specialist is working on a new flagship model. Despite looking very much like an AMG GT R wrapped in a swirly black-and-white disguise, this prototype has one distinguishing feature – a different exhaust system with quad pipes sticking out in a Lexus-like stacked design. Normally, the GT R breathes through a large central outlet.
