The biggest changes are found under the hood, where the 6.4-liter Hemi V8 engine has been upgraded to generate 475 horsepower at 6,000 rpms and 470 pound-feet of torque at 4,300 rpms, increases of 5 ponies and 5 pound-feet over the outgoing 2014 model. An eight-speed automatic transmission controlled by shift paddles is carried over from last year’s model.
The hot-rodded Grand Cherokee SRT comes standard with a new Active Noise Cancelling (ANC) system. Using strategically-located microphones, the system automatically mutes road noise in order to let passengers enjoy the SRT’s throaty exhaust note. Jeep promises the ANC technology provides a noticeably more refined ride.

Inside, the package adds model-specific black chrome trim and contrasting red accents. SRTs equipped with the Red Vapor special edition package can only be ordered in Redline Red, Brilliant Black or Bright White.
