The GT 63 is available in two very similar trims. Both are fitted with a 4.0-liter twin-turbo V8, a nine-speed MCT automatic gearbox, and all-wheel-drive. Adaptive air suspension, rear-wheel steering, launch control, and adaptive LED headlights are standard and a pair of 12.3-inch screens are included: one for the infotainment system and one as a driver info display. Customizable 64-color ambient lighting, dual-zone climate control, satellite radio, a 14-speaker Burmester audio setup, and a sunroof are all standard, too, making the AMG GT 63 incredibly well-equipped. The difference between the two models lies in engine output, with the base version producing 577 hp and 590 lb-ft of torque while the S model makes 630 hp and 664 lb-ft. The S model also has access to an optional carbon fiber roof and has race and drift modes as standard, but other options are shared between the two variants. These include features like tri-zone climate control, a head-up display, massaging front seats, ventilated rear seats, and a panoramic sunroof.
