A unique blend of capacity and distinctive design

NASREC, Johannesburg – Since its introduction in 1992, the Jeep® Grand Cherokee has revolutionised the sport-utility (SUV) market. With best-in-class tractive capability and best-in-class power, the Grand Cherokee Overland is designed, engineered and built to master every imaginable day-to-day driving condition, whether on-road or off-road.

With its upright and substantial posture, the Jeep Grand Cherokee’s design offers an athletic and contemporary appearance.

The exterior design has a high belt line and a reduced glass-to-body proportion that stays true to the authentic Jeep character.

With the signature seven-slot grille and trapezoidal wheel openings, the Grand Cherokee exudes sophistication for a distinctively Jeep design statement that easily moves from the outdoors to the opera. Additionally, platinum accents on the grille, rear view mirrors, door trims and badges add a high-tech appearance to the Overland models.

Interior

Jeep Grand Cherokee takes capability and refinement to new levels. An inviting interior awaits occupants with a rich, two-tone instrument panel treatment, door trims and upscale interior finishes.

Grand Cherokee Overland offers many premium features as standard, including leather and real wood steering wheel, wood door and console trim bezels, side air bags, ParkSense, Tyre Pressure Monitor and leather-trimmed seats with leather-wrapped centre console armrest.

Grand Cherokee Overland’s seats are beautifully crafted with contours that are precise, firm and ergonomic, featuring a robust structure. Covered with two-tone Royale leather trim, suede inserts for added comfort and beauty, accent stitching and the “Overland” logo embroidered on front seat backs ensuring these are purpose-built and designed for long-distance comfort.

Additionally, the heated front seats feature electrical adjustment memory function for two drivers. This is also coupled to the exterior rear view mirrors.

Whilst the sound of the 5,7l HEMI may be all the music many drivers wish to hear, the Overland is fitted with a Boston Acoustics premium sound system with six speakers and a 276 watt amplifier with digital sound processing for crystal clear music enjoyment. The optionally available DVD Video Entertainment System (VES) with wireless headphones and rear seat video overhead screen will keep rear seat passengers entertained on those long trips.

Quadra-Drive II

The Quadra-Drive II Jeep 4×4 system offers customers the ultimate in off-road capability. It combines the NV245 full-time transfer case with Electronic Limited Slip Differentials (ELSD) for best-in-class tractive performance. The system instantly detects tyre slip and smoothly distributes engine torque to the tyres with traction. In some cases, the vehicle will even anticipate low traction and adjust to proactively limit or eliminate slip.

The heart of the system is the NV245 active transfer case. This transfer case includes a centre differential coupled with an electronically controlled clutch pack, varying it from a completely open state to completely locked and infinite possibilities in between. The ‘4-Low gear’ ratio is 2,72:1.

A key component in the Quadra-Drive II system is the ELSD — an industry-first application – front/rear/centre and the benchmark for automatic traction differentials. The ELSD uses electronically controlled clutch packs to automatically and instantly vary from slip to lock at each axle. This maximises traction when needed without any of the on-road drawbacks normally associated with such a robust 4×4 system.

All components of the system work together, continually monitoring needs, to provide smooth and automatic application of the components for best-in-class tractive performance while improving the day-to-day on-road driving experience. For example, the ELSD releases the clutch packs in the front axle during turns to allow differentiation and prevent crow hop.

5,7l HEMI® V8

The 5.7l HEMI V8 is a highly refined power plant that delivers outstanding performance and reduced noise, vibration and harshness. The engine produces 240 kW at 5 000 r/min and 500 Nm at 4 000 r/min.

The engine gives the Grand Cherokee best-in-class power, while 90 % of the engine’s peak torque is available from 2 900 r/min through to 5 100 r/min for excellent performance. The engine features the Multi-Displacement System (MDS), which deactivates four cylinders when V8 power is not required. The Chrysler Group was the first manufacturer to offer fuel-conserving MDS in an SUV.

Some of the significant technologies enabling MDS include the speed of electronic controls, the sophistication of the algorithms controlling the systems and the use of Electronic Throttle Control (ETC).

Suspension and steering systems

The short- and long-arm independent front suspension on Grand Cherokee provides the driver with a greater sense of precision and control and more precise steering, and reduces vehicle weight and head-toss, all without compromising the vehicle’s off-road performance. The five-link rear-suspension geometry, including a track bar, also improves lateral stiffness to match that of the front suspension for optimum handling.

Electronic Stability Program (ESP), which is standard, aids the driver in maintaining vehicle directional stability in severe manouvre on any type of surface. It works by using signals from sensors throughout the vehicle that then determine the appropriate brake and throttle adjustments for directional stability.

Grand Cherokee’s rack-and-pinion steering imparts more precise steering to the driver, providing quick response during all types of maneuvers.
