Mercedes is launching the new AMG GT 63 S with a spare-no-expense Edition 1 package. The Edition 1 is available only on the range-topping GT 63 S model and adds the active AMG Aerodynamics Package to the standard all-wheel-drive and 630-horsepower, twin-turbo V8. Exterior touches include black accents on the 21-inch wheels and black stripes on the side sills, hood, roof, and trunk lid, and the choice of one exterior color — Graphite Grey. The interior has yellow seat belts, contrast stitching, and Edition 1 plates throughout. The Edition 1 will be available for one year only starting in early 2019.
