While MY17 MU-X signalled a massive change for the better in Isuzu Ute Australia’s (IUA) SUV line-up, this year is more of a subdued affair.
Last year heralded the arrival of a new 3.0-litre engine, new six-speed automatic transmission, and upgraded Aussie-specific suspension, as well as styling tweaks; MY18 MU-Xs get extended service intervals and a new exterior colour.
It’s a clear case of IUA applying a ‘if it ain’t broke, don’t fix it’ approach to its popular ute-based SUV.

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.

The MU-X is a solid SUV wagon and it only continues to gain more appeal and, with it, a growing legion of fans. You certainly see a lot of them around – in the bush, in the suburbs and on city streets.
It’s not flash or posh but it’s a very practical daily driver or weekend tourer and performs very well in the real world. The top choice for me remains the LS-T.

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.
This launch marked no noteworthy styling changes in the MU-X, inside or out. It remains a blocky but good-looking unit, blending a bush-ready appearance with styling that doesn’t look out of place in an urban setting.
Build quality and fit and finish seem as sturdy as we’ve come to expect from IUA’s mainstream offerings.

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 MU-X’s cabin, unchanged, should remain an easy place in which to travel. It’s roomy enough for everyone.
The second row is a 60/40 split-fold with a fold-away centre armrest. The third row is a tight fit for adults but that’s nothing unusual in most seven-seaters.
There is 235 litres of boot space when the third row is up, expanding to 878 litres when the 50/50 split-fold third row is folded flat. When the second and third rows are down, there is 1830 litres of space.
The MU-X has 12 cupholders, 18 'storage solutions' (door compartments with bottle bulge, coat hooks, rear cargo organiser box, etc), USB ports (front and rear) and three 12V power outlets (centre dash, glove box and rear cargo area).
The MU-X has a braked towing capacity of 3000kg, 750kg unbraked.

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.

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.
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.
We spent very little time in any new models and we’d have to drive a MY18 MU-X for a week or more to get a good handle on real-world fuel consumption but Isuzu claims the MU-X gets through 7.9L/100km (combined) in 4x4 LS-U and LS-T guises, 8.0L/100km (combined) in 4x2 LS-M, and 8.1L/100km (combined) in 4x2 LS-U and LS-T and 4x4 LS-M.
Every MY18 MU-X has a 65-litre fuel tank.
Jeep Grand Cherokee7/10
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.
Running 20 psi (pounds per square inch) in our Bridgestone Dueler or Toyo Open Country tyres, the Isuzus handled everything on the 4WD loop with ease, including runs up and down steep greasy-muddy hills peppered with rocks and tree-root hazards, tight turns in between trees, plowing through mud puddles and more.
No surprise at its efficacy on rough terrain because the D-Max and MU-X work off the proven '4X4 Terrain Command' system, operated via a dial near the auto shifter, and which can be switched on the move from 2High to 4High at speeds of up to 100km/h.
To engage 4L you need to be stationary.
The MU-X is 4825mm long, 1860mm wide (excluding wing mirrors), 1860mm high (the 4x2 LS-M is 1825mm high) and has a 3095mm wheelbase and 1570mm track. It has a 11.6m turning circle. Kerb weight is listed as from 1992kg (4x2 LS-M) to 2157kg (4x4 LS-T).
All MU-Xs except 4x2 and 4x4 LS-M models (220mm), have 230mm ground clearance. All MU-Xs except 4x2 and 4x4 LS-M models have 24 degrees approach angle (LS-M: 23.3), 25.1 degrees departure angle (LS-M: 24.6), and 19.5 degrees ramp-over angle (LS-M: 18.7).
The MU-X retains the benefits of the previous generation’s hill start assist (designed to hold gear during climbs) and hill descent control (which maintains engine-braking speed on downhills and is able to be regulated with acceleration or braking).
Underbody protection includes under-front steel plate skid/splash shield on every MU-X; and steel plate guards on the sump, transfer case and fuel tank leading edge on all 4x4 models.

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.
The MU-X has a maximum five-star ANCAP rating from April 2017.
Standard safety gear includes six airbags (dual front, side and full-length curtain), ABS with electronic brake-force distribution, ESC, traction control and EBA (emergency brake assist), 'Hill Start Assist' and 'Hill Descent Control', plus three top-tether ISOFIX child-seat points in the rear seat.
Jeep Grand Cherokee7/10
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.
Servicing is recommended at 12-month/15,000km intervals. Prices are: $350 (at 12 months/15,000km), $450 (at 24 months/30,000km), $500 (at 36 months/45,000km) $450 (at 48 months/60,000km) and $340 at 60 months/75,000km – for a total cost of $2090.
Jeep Grand Cherokee8/10
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.
