Mercedes two-door AMG GT gets the plug-in hybrid treatment, making it the fastest accelerating road-going Mercedes ever. Positioned as the new flagship model in the GT line-up, the GT63 S E Performance combines the usual twin turbo V8 with a rear-mounted electric motor that produces 201 hp on its own. When their powers combine, the GT’s output rises up to 805 hp and 1,047 lb-ft. All of that power and torque is fed through a nine-speed AMG Speedshift MCT transmission and AMG’s 4Matic+ variable all-wheel drive system, enabling a 0 to 62 mph acceleration time of just 2.8 seconds.
