In July 2020, Mercedes-Benz debuted its newest vehicle in the coveted Black Series lineup: the AMG GT Black Series. Incorporating lessons learned while endurance racing the AMG GT3, the engineers built the ultimate mix of street and track performance and one of the most hardcore road cars to come out of Affalterbach.

Immediately apparent are the aesthetic changes, from the revised grille opening to the exaggerated extractor vents on the hood. Less obvious are the changes to the bodywork, which is largely crafted from carbon fiber, with panels including the hood, roof, side skirts, rear hatch, and underbody cladding composed of the lightweight material. To improve downforce, an adjustable front splitter pairs with a rear spoiler featuring an active aero flap, helping the GT Black Series produce 882 pounds of downforce at 155 mph while making it look like a GT3 race car for the road.

Powering the Black Series is a variant of the M178 4.0-liter, twin-turbo V-8 from the AMG GT R, but sufficiently revised to gain its own designation: the M178 LS2. The largest change is the switch from a cross-plane crankshaft to a flat-plane crankshaft, which necessitated a new firing order and raised the redline to 7,200 rpm. Additional modifications to engine internals and improved turbochargers combine for serious power, with the GT Black Series producing 720 hp and 590 lbs./ft. of torque. A unique AMG coil-over suspension with active damping is fitted, as are carbon ceramic brakes that offer fade-free performance.

In November 2020, Mercedes-AMG factory driver Maro Engel drove an AMG GT Black Series around the Nürburgring Nordschleife in 6:43.616, setting a record time for a production vehicle around the track.

This 2021 Mercedes-AMG GT Black Series is finished in Cirrus Silver Metallic over black Nappa leather with Dinamica microfiber inserts. Showing just 456 miles at the time of cataloguing, this car has spent its life in the possession of the consignor, a Mercedes-Benz collector who has also campaigned an AMG GT3 race car in the IMSA series.

Although this car was designed with an eye towards on-track performance, this example is optioned with several features that make for far more pleasant road driving, such as the Lane Tracking Package, which includes blind-spot assist and lane-keep assist, as well as the Burmester High-End 3D Surround Sound System. With around 1,700 units built worldwide and fewer than 400 earmarked for the US, the AMG GT Black Series is likely one of the final, solely combustion-engine supercars to come from Mercedes-Benz, and the textbook definition of a modern collectible.
