Jeep Grand Cherokee
What a time to be alive people. There have never been more SUVs to take your pick from. But while many are excellent, there sure are a lot out there that are a bit... samey, and conservative, a little domesticated.
First it's made in the United States of America, in Detroit, and that's becoming a rarity these days. Next, the line-up is like a kooky gang of super heroes all with different powers.
There's the monster high-performance V8 one which can out accelerate and out handle many sports cars; the tough off-road one that can lift itself higher than its rivals with its air suspension; there's posh one, the popular one nearly everybody buys and the rear wheel drive one hardly anybody does.
|Engine Type||3.0L turbo|
The world of upper large luxury SUVs, like Infiniti’s latest-generation QX80, occupies that rarefied air, way up high in the car market, that I’ll never breathe – and that’s okay with me.
You see, as much as I admire these plush vehicles, even if I did have the cash and the inclination to buy one, I’d be so worried about incidental damage to the exterior (shopping trolleys or other drivers’ touch-parking) or children-induced damage to the interior (car sickness, spilled food or drink, blood from sibling punch-ups in the second row) that I’d never be able to fully relax while driving the thing. (Newsflash: I’ve heard from Infiniti that the QX80’s upholstery has a soil-resistant coating.)
These pricey wagons certainly do have their fans though and now, with extensive exterior changes and some interior ones, does the QX80, based on the Y62 Nissan Patrol, actually offer anything to set it apart from other large premium SUVs? Read on.
|Fuel Type||Premium Unleaded Petrol|
Jeep Grand Cherokee7.9/10
Not many SUV brands out there have ranges offering a variety of vehicles as wide as the Grand Cherokee line-up. These are comfortable, good looking, and in nearly all cases, capable off-roaders – particularly the Trailhawk.
The sweet spot of the range is the Limited. It's excellent value, and there's no wonder it's so popular. The SRT is also hard to go past if you're after more of a sledgehammer – at almost $10,000 under 100K it's bang-for-your-buck that can't be beaten.
Is the Jeep Grand Cherokee the best large SUV under $100k? Let us know what you think in the comments below.
The petrol-only QX80, really a Y62 Patrol with shedloads of bling, is a curious beast; a big, bold status-boosting premium SUV, which is much better suited to the US and Middle East markets than ours. However, it has a real premium feel, is very smooth to drive and the exterior and interior changes have improved what has so far been a divisive model for a brand with a small but growing fanbase here. Infiniti sold 83 of the previous QX80 in 2017 and is hoping to move 100 of these new ones in 2018; they have their work cut out for them, but if brand confidence is worth a few sales, who knows, they might even top the ton.
Is the QX80 worth its hefty price-tag, or is it simply too much cash for something that doesn’t even have mainstream connectivity functions?

New one look like the old one? Yup, the styling changes are almost unnoticeable, but the trademark seven-slot grille is slimmer, the front bumper has a new design and the fog lights use LEDs.
The Grand Cherokee's look is distinctive with its big toothy grille, high waistline and pumped up guards. It's an American muscle SUV – especially the SRT with its nostrilled bonnet, enormous air intakes, blacked-out face and red Brembo brake calipers.
The new Trailhawk rivals the SRT for attention-seeking-but-still-functional bling with its red tow hooks and badging. Look closely and you'll see small profiles of a WW2 Willys MB Jeep on the wheels, which is a cool touch.
The Grand Cherokee's cabin is comfortable but more functional than stylish, higher grades feel plush with their leather seats and wood trim finishes.
The Grand Cherokee's dimensions reveal all variants apart from the SRT to be 4828mm long and 1943mm wide. The SRT is longer at 4846mm and wider at 1954mm across the hips.
The heights vary depending on the variant with the Laredo and Limited standing 1802mm tall, while the Trailhawk and Overland are 1792mm. The SRT is hunkered down lower at 1749mm.
The Trailhawk and Overland have an approach angle of 36 degrees, a departure angle of 27 degrees and a breakover angle of 22 degrees. Those trump the angles for the Laredo and Limited which are 26 degrees for approach, 24 for departure and 19 for the breakover.
The SRT will still be competent off-road but its approach angle of 18 degrees, a departure angle of 22, and a breakover angle of 18 means it's more suited to less challenging dirt and gravel roads.
The bulk of the facelifted QX80’s design changes have been to the exterior and include, most noticeably, new LED headlights with a redesigned, sleeker but more aggressive front end than its predecessor’s softer, more rounded curves.
The new QX80’s bonnet is 20mm higher than before and has been extended 90mm; the side steps have been stretched 20mm wider, and the power tailgate has been re-designed to include sharper, thinner, rear LED taillights and the bumper is visually wider.
The whole body has a higher visual centre of gravity, with this latest raft of design shifts giving the SUV a taller, broader, wider and more angular overall appearance.
The interior includes a bigger, chunkier redesigned centre and rear console and those aforementioned premium touches, such as leather-wrapped heated steering wheel, updated upholstery-stitching, semi-aniline quilted leather patterning on door panels and seats, as well as its stainless-steel sill plates, all add to the premium feel.
The QX80 looks better than it did but, as the previous one was pretty hard on the eyes, the 2018 version may still polarise opinion.

All Grand Cherokees are five seaters. Legroom in the back is just enough… for me. I'm 191cm tall and the only reason I can sit behind my driving position is because of the concave design of the front seatbacks – and that gives me a gap of about 20mm. Headroom is great back there.
Up front there's stacks of head and shoulder room, although the driver's footwell feels a little cramped with the transmission tunnel above the bellhousing seeming to eat into the space.
There's a decent boot with a capacity of 782 litres and under the floor is a full-sized spare with storage space around it - you'll also find a rechargeable torch in the cargo area which 'clicks' into the boot wall.
Storage throughout the rest of the cabin is good with two cupholders in the fold down centre armrest in the back and another two up front. There's a deep centre console bin and bottle holders in all doors.
The QX80 is a big unit – 5340mm long (with a 3075mm wheelbase), 2265mm wide and 1945mm high – and, when you’re seated inside it, it feels like Infiniti designers and engineers must have worked hard to maximise the space afforded them for driver and passengers without seeming to have sacrificed any style or comfort.
And that big open space inside the cabin is easy to get comfortable in. There are soft-touch surfaces everywhere – door panels, arm rests, centre-console edging – and the seats are unsurprisingly soft and supportive but tend towards slippery when there are quick changes in speed or direction, or when tackling steep downhills off-road. (It was fun to watch front-seat passengers slip-slide around inside during the 4WD loop)
If you’re up-front you’re well catered for; big glovebox; overhead sunglasses storage; the centre console now has a roomy smartphone storage area; the twin cupholders have been upsized to cop two 1.3-litre cups with handles (up from one 1.3-litre cup and a 950ml container); the USB port has been moved to the other side of the centre console so it’s easier to get to; the storage area under the front passenger arm-rest is now a 5.4-litre compartment, able to hold up to three upright 1.0-litre bottles or tablet devices.
There are nine cupholders and two bottle-holders in total in the QX80.
There’s a sunroof if you get the urge for natural light from above.
Second-row passengers now get 8.0-inch entertainment screens (up from 7.0-inch) and two additional USB ports.
The tip-up second row seats are easy enough to operate and the third row is power 60/40 split-fold-to-flat and reclining.
There is a 12V outlet in the cargo area.
Price and features
Jeep Grand Cherokee8/10
There's the $52,500 petrol Laredo 4x4 (the diesel version is $5500 more); then the popular Limited which lists at $62,500 ($5500 more for the diesel); the diesel-only Trailhawk at $74,000 is a new off-road hero variant; then there's the plusher $80,000 Overland with the same engine, and finally the high performance, petrol-only SRT for $91,000.
All V6 petrol engine variants have increased by $500 over the outgoing model, while the diesels stay the same – apart from the Overland which has risen by $1000. The SRT has also gone up by $1000.
At the most affordable end of the range the Laredo grade comes standard with 18-inch alloy wheels, an 8.4-inch touchscreen (5.0-inch in the 4x2), 7.0-inch instrument cluster display, reversing camera, front and rear parking sensors, power adjustable and heated front seats, proximity unlocking and start button, auto headlights and wipers, and dual-zone climate control.
The Limited grade picks up the Laredo's features and adds 20-inch alloy wheels, a power tailgate, leather seats, a nine-speaker Alpine stereo, sat nav, dark-tinted rear glass, heated steering wheel and dual exhaust.
The Overland gets the Limited's features and adds a panoramic sunroof, adaptive cruise control, auto parking, ventilated front seats, plus a wood and leather steering wheel.
The SRT gains the Overland's features and adds a flat-bottomed steering wheel, leather and suede seats, launch control, active noise cancellation and adaptive damping.
Pricing has not changed: there is one model and it still costs $110,900 before on-roads and that price does not include paint other than the standard Black Obsidian; metallic paint is $1500 extra. Changes over and above the previous model’s standard features list include 22-inch 18-spoke forged alloy wheels (up from 20-inch), Infiniti’s InTouch 8.0-inch colour touchscreen (up from 7.0-inch), new Espresso Burl coloured trim, new chrome finishes all-round, updated upholstery-stitching everywhere, quilted leather patterning on seats, new headlights, LED foglights and more. There is no Apple CarPlay or Android Auto.
Engine & trans
Jeep Grand Cherokee9/10
The engine line-up for the Grand Cherokee is straightforward. The petrol engines for all but the SRT are an upgraded version of the previous model's 3.6-litre V6 with 3kW more power for a total of 213kW. Torque stays put at 347Nm.
The SRT is special – under that nostrilled bonnet there's 6.4 glorious litres of naturally aspirated V8 Hemi making 344kW/624Nm. Jeep has left this one untouched from the previous model, too.
The Trailhawk and Overland have Jeep's 'Quadra-Drive II' 4WD system which makes them more capable off-road then the Laredo and Limited with their 'Quadra-Trac II' permanent 4WD.
The major difference between the 4WD systems being that Quadra-Drive II has an electronic slip differential while the other uses traction control and braking to counter slippage. The SRT has the 'Quadra-Trac Active On-Demand' 4WD system.
The previous generation’s 5.6-litre V8 petrol engine (298kW@5800rpm and 560Nm@4000rpm) remains, as does the seven-speed automatic transmission with adaptive shift control. It also has Infiniti’s all-mode 4WD system, which offers Auto, 4WD High and 4WD Low settings and it has terrain appropriate modes (sand, snow, rocks) able to be dialled in.

The diesel Laredo, which is 4WD, has a claimed combined fuel consumption number of 7.5L/100km. Ditto for the diesel Limited, Trailhawk and Overland.
After an hour of driving in the Trailhawk on highways and country roads our trip computer was reporting 11.7L/100km.
The SRT likes a drink. The V8 petrol engine has a claimed combined figure of 14.0L/100km and that's why the SRT didn't make it into the top five most fuel efficient SUVs list.
The QX80 is claimed to use 14.8L/100km. We reckon that fuel-consumption figure is very optimistic and if QX80 owners are partial to towing boats – as Infiniti reckons they are – or if they tackle some 4WDing, then that figure is going to climb much higher quite swiftly.

The Trailhawk and the SRT were the only variants available to test drive at the launch of the updated model.
The program was pretty intensive with an off-road leg, a stint at a racetrack and plenty of road driving in between.
The hilly off-road course we took the Trailhawks through wasn't the most challenging, but the rain changed that a bit making the grassy slopes and clay ruts as slippery as ice.
With the Trailhawk in low range and on its highest air suspension setting giving us 260mm of ground clearance we wriggled our way through the off-road course fairly easily. There were some steeper sections which required a bit of brute force and momentum to combat slippery clay and gravity but the Jeeps soldiered through without any dramas, and plenty of hilarious fun.
The Trailhawk's Kevlar-reinforced tyres weren't needed on this soft stuff, but there are thousands of kays of tyre-killing tracks with rocks like spear heads lying in wait all over Australia where they'd be handy.
Grand Cherokees all have a unibody construction, so if you're looking for more of a hardcore off roader in the Jeep range then the body-on-frame Wrangler may be a better bet.
The unibody construction gives the Grand Cherokee a more car-like ride and on the road the Trailhawk was comfortable and composed, although that air suspension is a little floaty.
At 100km/h the Trailhawk lowers itself for better aerodynamics, but there was a decent amount of body roll when pushing hard through corners… unlike the SRT.
The SRT's suspension is set up for higher performance with Bilstein adaptive dampers and hollow stabiliser bars front and rear. Sport and Track modes firm the suspension for better handling along with making the throttle more responsive.
I've driven the SRT on racetracks and the road before, but some quick laps around New Zealand's Pukekohe Park circuit brought back the grin that only 2.4 tonnes of metal seeming to defy all the laws of physics can induce.
That naturally aspirated V8 Hemi is a lazy beast that seems to take it's time to wind up rather than deliver the same brutal kick of the twin-turbo V8 in a Mercedes-AMG GLE63, still 0-100km/h in a claimed 4.9sec is quick. What it lacks in spontaneity it makes up for in theatrics – the gurgle at idle is delicious and it gets angrier the more you kick it in the guts.
The launch control function in the SRT is foolproof, too. Just press the button which looks like a dragstrip 'Christmas tree' on the centre console, place your left foot on the brake and plant your right foot on accelerator – release the brake and enjoy the jump to hyperspace… well, almost.
In the world of luxury SUVs big is king and this thing is definitely on the chunky side of big, but it doesn’t often feel too cumbersome for its own good, or too bulky to steer in and out of Melbourne’s bustling morning traffic with precision.
During this event, we did a fair chunk of driving – highway, country roads, gravel roads and a decent bit of 4WDing – and, surprise, surprise, it did pretty well, especially when things of this ilk usually exhibit the ride and handling of an old poorly-sprung couch on wheels.
It did, however, feel top-heavy at times and revealed substantial body-roll when pushed around corners at speed or even during some sections of slow, bouncy off-roading, so I’d be reluctant to experience what it would be like without hydraulic body motion control. However, we were willing to forgive it any rocking-and-rolling when that healthy V8 growl kicked in as we gave it the boot.
The 22-inch tyre-and-wheel combination is not the way I’d go if I was going to use the QX80 for any off-road forays but, having said that, we did fine on them, at road tyre pressures, over a decent off-road loop.
It has 246mm of ground clearance and 24.2 (approach), 24.5 (departure) and 23.6 (ramp-over) angles.
The QX80 has coil springs all-round and it was only ever caught out when it thumped through a couple of surprise potholes along a dirt road.
This Infiniti model has a claimed tare mass of 2783kg, but you wouldn’t have known it was that many kegs because it powered up steep and slippery bush tracks, through deep muddy ruts, over greasy rocks and through a few knee-deep mud holes with ease. It was as easy as pulling up, switching your terrain modes and dialling in your setting: 4WD High, 4WD Low or Auto. It has a locking rear diff and very capable hill descent control, which we tested on a few rather steep sections of track.
It’s nice to see vehicle manufacturers unafraid to put their off-roaders, even their pricey luxury ones, through a decent off-road loop at launch because it shows they have confidence in its capabilities.

The Jeep Grand Cherokee has been awarded the maximum five-star ANCAP rating. All Grand Cherokees have seven airbags, a reversing camera, trailer sway control, but only the Overland and SRT grades come standard with advanced safety equipment such as AEB and lane departure warning. The equipment can be optioned on all grades from the Limited up.
You'll find three top tether points and two ISOFIX points in the second row.
There's also a full-sized spare wheel under the boot floor.
The update has brought two more advanced safety items – blind spot monitoring and rear cross traffic alert but these are only standard on the Overland.
The QX80 does not have an ANCAP safety rating. Safety tech as standard includes blind spot warning, intelligent parking system, forward emergency braking, lane departure prevention (incorporating lane departure warning), distance control assist and predictive forward collision warning, Infiniti/Patrol intelligent rear view mirror (which can display video from a camera mounted in the upper rear windshield) and more. It has two ISOFIX points in the second-row seats.

There's also life-time roadside assistance if the vehicle's serviced at a Jeep service centre.
For the 3.0-litre diesel servicing is recommended annually or every 20,000km and capped at $665 for the first, $1095 for the second, then $665, then $1195 and at five years it'll be $665.
