These include the 18-inch Goodyear Silent Armor all-terrain tires with Kevlar reinforcement, solid steel rock rail body protection, Quadra-Lift air suspension with nearly 11 inches of ground clearance, Selec-Terrain traction control system and Quadra-Track II or Quadra-Drive II (V-8) with a two-speed transfer case.
In addition, the V8 model benefits from a rear Electronic Limited-slip Differential (ELSD) that can transfer up to 100% of engine’s torque to one rear wheel.
The 2013 Grand Cherokee Trailhawk can be identified on the outside by a styling package that includes special decals with accent stripes, black-surround headlamps and a unique gray on the grille surround, side mirrors, rear light bar, 4x4 badge and five-spoke 18-inch aluminum wheels.
Inside, Jeep has fitted the special edition model with black leather and suede seats with red accent stitching and Mopar floor mats.
Both models benefit from the addition of 20-inch wheels with black chrome finish and gloss black exterior appointments including hood badge, Grand Cherokee door logo, front grille surround and inserts, and a rear light bar and step pad.
There are no under-the-hood upgrades with the two special edition SRT8s being powered by the standard 6.4-liter Hemi V8 delivering 471hp (477PS) and 465 lb.-ft. (630 Nm) of torque.
Jeep quotes a 0-60 mph time of 4.8 seconds, 0-100-0 mph in the mid-16 second range, the quarter mile in the mid-13 second range, a top speed of 160 mph (257km/h), and braking from 60-0 mph (96-0km/h) in 116 feet (35.4m).
The 2013 Grand Cherokee SRT8 has a Manufacturer’s Suggested Retail Price (MSRP) of $59,995 (plus $925 destination), while Jeep commands a $2,495 premium for the Alpine and Vapor special edition packages that brings the total to $62,490 or $63,415 with destination.
