The SRT8 has 6.4-liter V-8 under the hood that produces an estimated 465 horsepower and 465 lb.-ft. of torque. The SRT8 is equipped with a five speed automatic and drives all four wheels. A unique front fascia, lower ride height, body colored cladding and a rear liftgate spoiler visually differentiates the SRT8 from other Grand Cherokees.
