Like ABT is to Audi, Brabus is to Mercedes. These are the tuners that come to mind when you talk about the respective brands. Brabus is here with another creation called the Rocket 900 One of Ten thats based on the Mercedes-AMG GT63 S. The Brabus model comes with changes inside and out, but the biggest changes have happened under the hood. The car didnt just receive some extra horses and torque; Brabus also increased the displacement of the V-8 powerhouse. The car is super-exclusive and only 10 examples of it will be built.
