Mercedes-AMG's GT is getting a big upgrade in power and a new Stealth Edition trim package for the 2021 model year. A 54 horsepower jump to a total of 523 is standard across the range, along with a longer list of standard equipment like AMG Ride Control with dynamic dampers, an electronically-controlled limit-slip differential, and composite brakes with red AMG calipers. The Stealth Edition removes anything that might be slightly reflective and paints it black, making for a menacing look that suits the GT's classic long hood-short deck styling perfectly. Staggered 19-inch front and 20-inch rear wheels come on the coupe and roadster, while the coupe gets a carbon fiber roof with darker black areas. The interior gets AMG sport seats and the AMG Interior Night Package, quilted leather seating, and black piano lacquer trim. The new GT and Stealth Edition will arrive in early 2021.
