Black Series or not, the AMG GT R is due for some upgrades if this test mule is anything to go by

The Mercedes-AMG GT coupe has been shoved into the background of late thanks to the launch of its GT 4-Door relative at this year’s Geneva motor show. But the ‘real’ GT isn’t being left to over-ripen in the model range if this test mule spotted at the Nürburgring is anything to go by. 

Look closely and you’ll notice that this GT R is sporting a more aggressive front splitter with vertical supports, plus canards on either side of the outer cooling ducts. This is balanced at the rear with a larger wing and the use of AMG’s development wheels on the rear axle – wheels that have also been spotted on other AMG prototypes.

We aren’t sure that the spied changes constitute this being the hardcore Black Series model that AMG has cunningly neither confirmed nor denied – AMG boss Tobias Moers stated that ‘there is room above the GT R and we haven’t done a Black Series in a while’ in a recent conversation with us – but this is a sign that an even more potent version of the AMG GT is currently in development, regardless of the form it will take.

 

Currently, the most powerful car in the AMG line-up is the forthcoming GT63 S 4-Door, featuring the M177 4-litre V8 with 470kW, some 40kW up on the GT R. If (when) a GT Black Series arrives, we’ll be expecting it to carry a generous power upgrade compared with the GT R’s 430kW, as well as a weight reduction through an extended use of carbonfibre and lightened glazing.

AMG is remaining tight-lipped about the future of the GT R, but as rivals such as the 488 Pista and Porsche 911 GT2 RS come on stream, the company will not want to be left out of the hardcore supercar game. The GT’s high-profile predecessor, the SLS, was at its best in Black Series form – let’s hope we have the chance to say the same about the GT.
