With just over 500 horsepower and 479 pound-feet of torque at its disposal, the Mercedes-AMG GT S is far from what you or I would consider a supercar. It’s got some burn to it, sure, but it’s not going to win any races when you line it up against the Lamborghinis and Ferraris of the world. Imagine, then, what kind of program it would take for the AMG GT S to have the muscle for that action. Well, stop imagining because it’s actually come to life, all thanks to the fantastic folks over at IMSA. For your enjoyment, folks, I present to you the Mercedes-AMG RXR One Super Gran Turismo by IMSA.
