Like a sprinkling of fresh snow, Jeep has topped off its Grand Cherokee premium SUV range with added features for the Summit. At the peak of the Jeep model range, the maker says the bolstered Summit Platinum will satisfy drivers who demand luxurious comfort and supreme refinement.

Exterior styling has been built upon by Platinum Chrome detailing. The premium finish features body-colour lower body trim, mirror caps and door handles, complemented by Platinum Chrome accents on the grille, lower fascias and side sills, foglamp bezels, rear step pad and badging.

Interior upgrades include illuminated ‘Summit’ doorsills and a deluxe Berber carpet cargo compartment floor mat. Cabin refinement is improved with the addition of an acoustic front and rear windscreen and acoustic second row door glass this is complemented by the standard Active Noise Cancellation.

At $78,000, plus on-road costs, the Platinum Summit is in the frame with some serious competition from the likes of Audi, BMW, Range Rover and Mercedes-Benz. Does it have enough to attract buyers in this market? It’s anybody’s guess.

Jeep’s idea of giving the Grand Cherokee Platinum Summit distinctive exterior styling is to add chrome – lots of it – which only goes to emphasise the size of the vehicle: almost five metres long and two metres wide.

The symphony of chrome includes ‘Grand Cherokee’ driver and passenger door badges, front and rear ‘Jeep’ badge, grille inserts, front fog lamp outer bezel, lower fascia applique, rear boot step pad and rear tail lamp bezels. Oh, and 20-inch alloy wheels are finished in Platinum Chrome.

Occupants are welcomed with illuminated ‘Summit’ door sill plates, while a deluxe Berber carpet floor mat gives the 782 litres of rear cargo space (with the rear seatbacks raised) an air of respectability not normally found in the boot of an off-roader.


With room for only five in the cabin, there is plenty of room to spread out and long journeys are no chore. Occupants also have the benefit of Jeep’s CommandView panoramic sunroof, comprising two glass panels, providing a huge glass surface. The powered front panel opens rearward, while the rear panel, which is fixed, allows light and open viewing for second-row passengers. The system comes complete with a full-length power sun shade protecting against direct sunlight, the latter with limited effect in searing mid-summer Australian sunlight.

Premium touches include leather and timber trim, while the steering wheel design incorporates controls for radio, cruise control, telephone and voice commands. All Grand Cherokee models are fitted with paddle shifts mounted on the back of the steering wheel.

Comfort and convenience extend to an array of innovative advanced technology. A new Uconnect system includes an easily accessible 8.4-inch tablet-style touchscreen, combined with a customisable multi-view instrument cluster display.

The Uconnect 8.4 system is designed to facilitate a fully integrated infotainment experience within one solution, meaning all feature components including GPS, voice recognition and additional entertainment features are built into a single hardware platform, instead of being delivered as separate components.


The star of the show, so to speak, is an Active Noise Cancellation system, resulting in a 10 dB reduction in interior noise, enhancing music clarity due to reduced engine clatter inside the cabin.

Developed by premium audio specialists Harman Kardon, it allows the Grand Cherokee Summit Platinum’s 825-watt, 19-speaker audio system to be heard clearer and appreciated better. This state-of-the-art system features a 12-channel amplifier, three sub-woofers and surrounds the occupants in high-definition sound.

Jeep Grand Cherokee Summit Platinum is available with an Italian-made 3.0-litre V6 turbo-diesel engine, which produces maximum power of 184 kW at 4000 rpm and peak torque of 570 Nm at 2000 rpm. The latter is 20 Nm more than the previous model and accessible almost 30 per cent lower in the rev range (previously 550 Nm at 2800 rpm).

Combined with the new eight-speed ZF automatic transmission, fuel consumption for the combined cycle is a claimed 7.5 litres per 100 kilometres, a 10 per cent improvement on the previous model, despite the increases in power and torque.

Compact and lightweight, the 3.0-litre turbo-diesel engine features a 1800-bar common-rail fuel injection system, a compressed graphite iron 60-degree block with aluminium cylinder heads and a two-piece structural aluminium oil pan.

Additional emission controls include a close-coupled diesel oxidation catalyst and standard diesel particulate filter. The engine compels with Euro 5-plus emissions regulations.

Summit Platinum weighs has Forward Collision Warning with Crash Mitigation, Adaptive Cruise Control, ParkView rear back-up camera with guidelines, ParkSense park-assist and new Selec-Speed Control with Hill Ascent Control and Hill Descent Control, helping the driver when climbing and descending steep grades in off-road driving.

Jeep Grand Cherokee Summit Platinum has a range of features including state-of-the art 4WD, electronic limited-slip differential, air suspension and a multi mode traction control system.

It is debatable how many owners will take their prized Grand Cherokee into extreme territory, but the systems are there to make the going as pleasant as possible.

On the street, the Grand Cherokee Summit Platinum is a big vehicle and needs to be treated as one, with parking a problem in limited space.

With more than five million sales worldwide in two decades since, as Jeep claims, the Grand Cherokee reinvented the premium sport utility vehicle, the Platinum version represents the new peak of the range.
