The 2013 Jeep Grand Cherokee SRT8 is the most powerful, technologically advanced, high-performance Jeep ever -- featuring a combination of Jeep's legendary capability and utility, merged with the renowned advanced performance engineering from Chrysler Group's Street and Racing Technology (SRT) team.
Delivering outstanding driving performance in all conditions, and complemented by key SRT attributes - including functional, performance-oriented styling, world-class ride and handling, benchmark braking and race-inspired interior appointments - the 2013 Jeep Grand Cherokee SRT8 runs from 0-60 mph in 4.8 seconds, 0-100-0 mph in the mid-16 second range, can cover the quarter mile in the mid-13 second range, has a top speed of 160 mph, and brakes from 60-0 mph in 116 feet.
Powering the 2013 Jeep Grand Cherokee SRT8 is the 6.4-liter HEMI® V-8 with Fuel Saver Technology that delivers 470 horsepower (351 kW) and 465 lb.-ft. (630 N•m) of torque.
An active intake manifold and high-lift camshaft with cam phasing delivers maximum low-end torque while optimizing high-end power across a wide rpm band. Specifically, 90-percent of peak torque is available between 2,800 and 6,000 rpm, allowing for inspired standing starts and improved straight-line performance.
Standard Fuel Saver Technology and an active valve exhaust system allows four-cylinder operation to engage over a wide rpm range, to deliver both fuel efficiency and an extended range of 450 miles on one tank of gas.
Outstanding ride, handling and capability
In 2011, all Jeep Grand Cherokee models received a vastly improved and refined on-road ride thanks in part to the vehicle's new body structure. Torsional stiffness was improved 146 percent versus the previous generation model, for improved ride, durability and reduced noise, vibration and harshness. The improvements were achieved with more than 5,400 welds in the body alone, marking a 53-percent increase in spot welds, a 42-percent increase in arc welds and a 38-percent increase in structural adhesive.
The 2013 Grand Cherokee SRT8 is the best handling Jeep vehicle ever - capable of .90 g on the skid pad - features a SRT-tuned, adaptive damping suspension managed by the Jeep Selec-Track system that interacts with several different systems (stability control, adaptive damping, transmission shift strategy, transfer case torque proportioning, Electronic Limited Slip Differential performance, throttle control and cylinder de-activation) to automatically tune the dynamics of the vehicle.
The standard Jeep Quadra-Trac SRT active on-demand four-wheel-drive transfer case uses input from a variety of sensors in order to determine tire slip at the earliest possible moment and take corrective action. The system uses Throttle Anticipate to sense quick movement in the throttle from a stop and maximizes traction before slippage occurs. When tire slippage is detected, the Jeep 4x4 system can transfer up to 100 percent of available torque to one rear wheel.
The transfer case also enhances handling by proportioning torque between the front and rear axles to maintain the driver's intended path. The Grand Cherokee SRT8 also features an Electronic Limited Slip Differential, which eliminates rear wheel slip and improves handling. Split 5-spoke, 20-inch forged aluminum wheels ride on P295/45ZR20 Pirelli Scorpion Verde All Season run-flat tires or available Pirelli P Zero Three-season.
Aggressive and functional exterior
The functional performance exterior of the 2013 Grand Cherokee SRT8 features the "planted" look of a high-performance sports car by being lowered 1 inch and adding SRT-exclusive, body-color wheel flares and side sill cladding. A one-piece front fascia contains LED multi-function daytime running lamps that result in an exclusive face for the Jeep Grand Cherokee SRT8, while a body-colored front grille with a unique black screen background and chrome bezel inserts add to the aggressive look. The integrated lower front grille is painted in gloss black and a underbody belly pan features integrated brake ducting to improve cooling and fade performance. Completing the front end is a sculpted hood with functional dual black heat extractors for added engine cooling.
At the rear, the SRT performance influence continues with a liftgate spoiler that reduces drag and improves downforce. A unique one-piece rear fascia includes a separate air diffuser along with an available trailer receiver and access cover. The dual-sport exhaust system features 4-inch exhaust tips. New for 2013 are two special models of the Jeep Grand Cherokee SRT8 including the bright white "Alpine" edition and brilliant black "Vapor" edition.
The leather-wrapped, heated steering wheel features a unique satin chrome rim section with a flattened bottom surface - evoking a race-inspired cockpit - that showcases the SRT logo. Standard paddle-shift controls flank both sides of the contoured palm rests while all audio and Electronic Vehicle Information Center (EVIC) controls are accessible from the horizontal spokes on the steering wheel. A power tilt and telescoping steering column also is standard.
Standard SRT-styled Nappa leather and suede seats, with sculpted bolsters and adjustable headrests, provide all the comfort for daily drives - and "grip" to keep the driver and passengers in place during spirited driving. The embroidered SRT logos and contrast stitching accent the two front seats. Heated (front and rear) and ventilated (front) seats are standard.
