It seems like Mercedes has been testing the ultimate variant of the AMG GT sports car for ages now, but finally there’s a light at the end of the tunnel as a test car was spotted with its final production bodywork, and it is wild.

And by wild, we mean proper, GT3-spec race car wild. The Mercedes-AMG GT R Black Series looks like it’s getting the same, enlarged front grille we saw in the GT3 race car a few months ago, accompanied by a set of winglets on each bumper side, a very deeply sculpted bonnet, air outlets on the front fenders and a massive double rear wing.

The redesigned bodywork will be combined with a much more powerful iteration of AMG’s twin-turbo 4.0-liter V8; in fact, we’ve learned that it will be essentially a new version of the engine offering close to 700 HP, up from the 577 HP the current V8 makes in the GT R and GT R Pro models.

This will position the new Mercedes AMG GT R Black Series among some pretty stiff competition, including the Porsche 911 GT2 RS, which is seen as the main rival for AMG’s finest specimen.

Of course the chassis of the new Black Series will be further sharpened and buttoned down in order to collaborate with the new aero kit, featuring a new suspension, more powerful brakes and stickier tires. Weight is expected to remain more or less the same with the GT R Pro, which tips the scales at 1575 kg (3472 lbs).

Last time Mercedes AMG gave us a Black Series model was in 2013 with the SLS Black Series. Affalterbach reserves the moniker for its finest cars only and the same should apply for the AMG GT R Black Series, which is expected to become the brand’s quickest accelerating model, this side of the AMG One hypercar.
