Mercedes-AMG has boosted the power of the twin-turbocharged 4.0-liter V-8 in both the coupe and roadster variants of the AMG GT for 2021. The hot-vee turbocharged engine now produces an impressive peak of 523 hp, up from 469 in the 2020 models. Mercedes says the extra sauce is enough to drop two tenths off the GT’s 0–60-mph run; both coupe and roadster do the sprint in 3.7 seconds.
The extra power is joined by various performance upgrades that, in 2020, were reserved for the higher-spec GT S or GT C models and will come standard on the 2021 base model. These goodies include an electronic limited-slip differential, AMG Ride Control active damping suspension, “Race” mode, a composite brake system, and a lithium-ion starter battery. Aside from the aforementioned 0–60-mph figure, Mercedes didn’t give us any numbers to compare how much those additions altered the GT’s weight or performance, but it did provide us with impressive power figures. The V-8 now produces 494 lb-ft of torque from 2100–5250 rpm and a constant 523 hp from 5500–6750 rpm. That’s some impressive turbo magic.
Also new for 2021 is a “Stealth Edition,” available on both coupe and roadster. The blacked-out special edition takes its low-key looks seriously. Its grille, headlights, brake calipers, and staggered 19- and 20-inch wheels all wear black. The coupe uses a carbon-fiber roof, while the roadster gets a black fabric top. Four colors will be available, including two greys, Obsidian Black, and, well, just plain old black. Inside your Stealth Edition, you’ll find a microfiber-wrapped steering wheel, quilted black leather, and black piano lacquer accents.
Mercedes says we can expect the new coupe and roadster to give the grand touring market a shot in the arm beginning in early 2021.
