This 2021 Mercedes-AMG GT Black Series has been modified with RENNtech’s R3 Package, which consists of ECU, turbocharger, and transmission control unit upgrades along with a performance clutch, blow-off valve adapters, BMC air filters, and stainless-steel downpipes with 200-cell catalytic converters. A matte black wrap was applied over the Graphite Gray Magno paintwork under previous ownership, and further revisions include an extended front splitter, a carbon-fiber rear bumperette delete, and a RENNtech roll bar. Powered by a twin-turbocharged 4.0-liter V8 paired with a seven-speed dual-clutch automatic transaxle, the car has an electronically controlled limited-slip differential, ceramic-composite brakes, 19″ and 20″ AMG Black Series forged wheels, heated power-adjustable performance seats, Black Exclusive Nappa leather and Dinamica upholstery, and COMAND infotainment with navigation. Acquired by the selling dealer in 2024, this AMG GT Black Series has 8k miles and is now offered with a window sticker, manufacturer’s literature, an accident-free Carfax report, and a clean New York title.

The Black Series features a revised front fascia with enlarged intercooler openings when compared to the standard AMG GT as well as an adjustable carbon-fiber front splitter, a two-stage rear wing with an electronically controlled center flap, and a carbon-fiber hood, roof, rear liftgate, front canards, side-skirt extensions, and front fenders. This example was finished in Graphite Gray Magno (818) from the factory and has been retrofitted with a matte black wrap, RENNtech badging, a front splitter extension, a carbon-fiber rear bumperette delete panel, and orange accents. Further details consist of power-folding side mirrors, front and rear cameras, a rear diffuser, and quad exhaust outlets. The majority of the photos in the listing gallery were taken in October 2024.

The 19″ and 20″ black AMG Black Series forged 10-spoke wheels are mounted with Michelin Pilot Sport tires measuring 285/35 up front and 335/30 out back. The car features adaptive coilover suspension with driver-selectable modes, and Black Series equipment includes a carbon-fiber front anti-roll bar and chassis bracing. Stopping power is provided by ceramic-composite rotors with orange-finished calipers and model-specific pads.

The cabin features heated power-adjustable AMG Performance seats trimmed in Black Exclusive Nappa leather and Dinamica with contrasting orange accents and stitching. Appointments include an orange RENNtech-branded rear roll bar, carbon-fiber trim, Keyless Go, dual-zone automatic climate control, and COMAND infotainment with navigation. The selling dealer states that a radar and laser detector has been added.

The AMG Performance steering wheel features an adjustable drive mode dial and frames a central configurable digital display. The digital odometer indicates 8k miles.

The twin-turbocharged 4.0-liter V8 received an oil change at approximately 5k miles, and it has been retrofitted with the RENNtech R3 Performance Package, which includes the following:

• Stage II turbochargers
• Revised engine management software
• Stainless-steel downpipes w/200-cell catalytic converters
• RENNtech blow-off valve adapter
• BMC air filters

A dynamometer sheet notes a maximum power output of 942 horsepower.

Power is sent to the rear wheels through a seven-speed dual-clutch automatic transaxle and an electronically controlled limited-slip differential. The car came equipped from the factory with a performance exhaust system, and the RENNtech R3 Performance Package includes an updated transmission control unit and a performance clutch upgrade.

The Carfax report lists an open manufacturer’s safety recall.

The current New York title carries a “Duplicate” notation.
