The 2020 Mercedes-AMG GT R Pro went into production last month, but fans looking for something even more extreme have to wait a bit longer.

We’re of course talking about the highly anticipated Mercedes-AMG GT Black Series which will serve as the pinnacle of the company’s sports car lineup. Mercedes has been talking about the model for years and it’s inching closer to production as spy photographers have snapped a prototype on the Nürburgring.

While the model shares a number of similarities with the GT R Pro, there are some of significant differences. Starting up front, the Black Series has unique canards which flow through the air intakes and connect to the Panamericana grille surround. The model also has beefier support brackets for the front lip spoiler.

Moving further back, there’s an additional canard above the front fender vents. The model also has unique side skirts which are more streamlined than those on the GT R Pro. The front and rear brake calipers also appear larger and they have an eye-catching bronze finish.

The rear of the prototype largely carries over from the GT R Pro, aside from the missing side fins and temporary exhaust system. While it obviously isn’t finished, we can expect a handful of changes on the road-going model.

Power will be provided by a twin-turbo 4.0-liter V8 engine. There’s no word on what it will be rated at, but the Black Series should be more powerful the GT R Pro which has 577 hp (430 kW / 585 PS) and 516 lb-ft (700 Nm) of torque. It could also be more powerful than the GT 63 S four-door coupe which has a twin-turbo 4.0-liter V8 with 630 hp (470 kW / 639 PS) and 664 lb-ft (900 Nm) of torque.

Regardless of the final output, Mercedes-AMG CEO Tobias Moers has suggested the GT Black Series will be launched in 2020.
