2019 Mercedes-AMG GT Black Series spied at the 'Ring

A prototype believed to be a more extreme 'Black Series' version of the Mercedes-AMG GT has been spied again, this time during performance testing at the Nurburgring race track in Germany. Compared to the prototype snapped in September, this vehicle is sporting a more aggressive aerodynamic setup, including a more pronounced front bumper and splitter with incorporated flics, and a larger rear wing.
