In Motor Trend`s Head 2 Head`s Episode 36, Jonny Lieberman is accepting another challenge. He is going to test the Mercedes-Benz SLS AMG Black Series` specifications as opposed to the SRT Viper.  Lieberman tries the 6.2-liter V8 with 622 horsepower and 468 pound-feet of torque of SLS AMG versus the 8.4-liter V10 with 640 hp and 600 lb-ft.

Regardless the numberings, these two cars have totally the opposite driving experiences. Lieberman first tests them on Northern California roads, and then randy Probst  tries them on Laguna Seca.
