Mercedes-AMG is going the Porsche route and milking the AMG GT for all that its got. Just as we have 100 versions of the 911, Mercedes-AMG just keeps on adding more hardcore versions of the GT.
Currently, we have the AMG GT, AMG GT S, AMG GT C, with the AMG GT R being the most hardcore version. All of those cars have drop-top versions except the Pro. So you get the picture.
Power ranges from 350 kW to 630 Nm in the GT to 430 kW and 700 Nm of torque in the GT R Pro.
People like Shmee haven't received their GT R Pros yet and now there are spy shots of an even more hardcore GT car testing in Europe.
