What's the difference?
The Holden Colorado is a quiet achiever in the ute market: it has a solid rep as a work-and-play vehicle, generally records positive results in objective editorial reviews and comparisons, and it sells well.
But how does a Z71 do as a tow vehicle? Read on.
For some strange reason, the Isuzu D-Max isn't often mentioned on the list of Australia's most popular vehicles.
You hear all about the Ford Ranger and the Toyota HiLux, of course. And you hear about the Toyota RAV4 Hybrid, the Tesla Model Y and a handful of others, too.
But let's give the D-Max its flowers. Last year, it was Australia's third best-selling vehicle, shifting more than 31,000 units in 2023. And it moved another 7947 vehicles over the first three months of 2024. That makes it a proper sales behemoth.
So far, it's the only ute that's been able to maintain touching distance to the Ranger and HiLux, and the brand has some pretty big sales ambitions for the model for this year and beyond.
I tell you all of this as a way to say that this updated 2024 model is a Very Big Deal, not just for the brand, but for the legions of ute fans across the country.
What's fresh? There's a new look, better safety kit, a new permanent trim level, new off-road capability and a better cabin experience.
Is that enough to keep it in the hunt with the best-selling utes in the country? Let's go find out.
The Holden Colorado Z71 is a pretty decent towing machine, handling all aspects of general load-lugging duties with a quiet reliable efficiency. In simple terms, it kept the whole ute-and-van combination trucking along nicely.
The Z71 is a solid Colorado package all-round with some welcome flashiness to its functionality.
The new D-Max hasn’t been majorly overhauled and instead bundles together a whole bunch of small but important changes, all of which have been designed to keep it fresh in the face of its competition, like the Triton, Ranger and HiLux.
Has it done enough? Only time will tell. But there’s little doubt that these updates only improve the D-Max formula.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.
The Colorado is a good-looking unit, so it follows that the Z71, the Colorado line-up's top dog, should be the best-looking vehicle in the entire range. And it is. Look at the photos yourself and make up your own mind.
The Z71's black highlights everywhere, the roof rails, side steps and fold-away tonneau cover add functionality to the flashiness.
Under its slick exterior, the Z71 sits on a steel ladder-frame chassis.
There may be no mechanical differences between the Z71 and other similarly-powered Colorado utes, but this is not merely a sticker-pack special – this is something more substantial than that. Don't believe me? Keep reading.
There are some big-ish changes for this new-look D-Max, but how many of them you get depends on which of the six trim levels you’re shopping for.
Spring for one near the top of the family tree, and you’ll get all of the updates, which include new-look headlights that are LED with LED DRLs (but halogens on the SX), and a new-look front-end and grille. At the rear, there are new LED rear light clusters.
It doesn’t look a million miles away from the current D-Max, to be honest, but it does look a little newer, and a little fresher, which is important in the battle of the inches that is the new-ute market.
Inside, the brand describes the cabin as a mix of utility and comfort, and that’s feels pretty accurate from the driver’s seat.
The tech is new, with the 8.0- or 9.0-inch central screen joined by USB connection points, and there’s a new Digital Driver Display screen in the mix, along with new seat materials and trims, too.
But back to that that mix of utility and comfort. I’m not sure Isuzu has gotten the mix exactly right. There are plenty of soft-touch materials in the higher-trim levels, just not always where I want them to be.
I don’t know about you, but I like to have my elbow up when driving, and that plastic is still scratchy and hard, as is the place where my knee touches the centre console.
That said, it’s largely comfortable, definitely functional, and it serves up pretty much exactly what you might expect.
The Z71 has a Colorado carry-over interior, which is nice and simple, with some Z71 branding stitched in the front seats.
For starters, there are grab handles for the driver and front passenger – I'm a big fan of grab handles.
The dash is a basic layout – but made family-friendly with expanses of tough plastic and soft-touch leather – and it has everything you need. The centre console houses an 8.0-inch colour touchscreen with Apple CarPlay and Android Auto and standard nav.
There is a USB port in the centre-bin, and there's a 12V socket in the back of that bin for back-seat passengers.
The cabin is reasonably comfortable; the front seats – in fact all of the Z71's seats – err on the side of firm rather than being well-cushioned. But, even in the back seat, when I sat behind my driving position, I had ample head- and leg-room.
There are the usual collection of storage spaces around the cabin – sunglasses, glove box, door pockets, seat-back pockets – but a long centre-bin lid impedes access to the cupholders in between driver and front-seat passenger, and there are no cupholders in the back seat's fold-down centre arm-rest.
There are shallow storage spots under the rear seats, one of which contains your jack etc.
Overall fit and finish is impressive without being spectacular, but that's fine with me.
The tray is 1484mm long, 1534mm wide (1122mm between the wheel-arches) and 466mm high. Back there, you get Premium DuraGuard Spray–on tub liner, which seems sturdy and durable, as well as four solid tie-down points.
Isuzu has taken to calling the D-Max one of Australia’s most capable utes out of the box.
That includes up to 240mm in ground clearance, 800mm in wading depth, and a towing maximum of 3.5 tonnes for the bigger diesel engine, dropping to three tonnes with the 1.9-litre powerplant fitted. Payload is up to 1405kg, too, but to get you need the SX with Cab Chassis. It’s more like 1045kg for most dual-cab ute trims.
Also new for this update is the addition of Rough Terrain Mode — a technology borrowed from the MU-X, then improved to pair with the D-Max’s mechanical off-road features.
In short, the tech taps into the traction-control systems to detect wheel slip, and can then brake individual wheels and send torque to where it is needed to smooth your progress. In the D-Max, it works with the rear diff-lock, too.
The back seat of the D-Max shows why vehicles in this category are now doubling as family vehicles. Behind my own 175cm driving position there was enough knee and headroom to get comfortable, and I’m confident you could fit three across the back row pretty easily, too.
There are some creature comforts, including a USB-C charging point (trim dependent) as well as air vents, but no temp controls, and even a little coat hook as well, but it’s not swimming with niceties.
The Z71 auto 4x4 dual-cab has a list price of $57,490 MSRP. Our test vehicle is $59,260 MSRP because, over and above its comprehensive list of Z71 features (and those from cheaper variants), it has an electric brake controller ($740), and a towing package ($1030).
The Z71-specific features include a heap of style-based stuff, such as black fender flares, new front fascia, roof rails, and stickers on the bonnet, as well as 18-inch grey alloys (on Bridgestone Dueler H/Ts), sailplane sports bar, black highlights everywhere – including exterior door handles, mirrors and tailgate handle.
But the Z71 buyer gets plenty of useable real-world stuff such as roof rails, soft-drop tailgate, fold-away tonneau cover, and decent underbody protection.
There's also a leather-wrapped steering wheel and leather seats.
It has a 2.8-litre four-cylinder turbo-diesel Duramax engine, six-speed automatic transmission, a part-time 4WD system and a rear limited slip differential.
Bonus: there are plenty of genuine Holden-designed, -engineered and -tested accessories, including frontal protection bars, LED light bars, extended sports bars and more, that are probably available for your Colorado.
Ute ranges being the insanely complex webs they are, you’ll be unsurprised to hear there are lots of options here. In fact, there are some 25 combinations, spanning six grades, two engines, two gearboxes, a choice of two- or four-wheel drive and four body styles.
The price range is vast, too, now starting at $32,700 for the SX Single Cab Chassis with a 1.9-litre turbo-diesel and two-wheel drive, and climbing to a $70,500 MSRP for the X-Terrain Crew Cab with a 3.0-litre turbo-diesel and four-wheel drive.
To keep this brief, we'll focus on the Crew Cab Ute, which is yours in SX, LS-U, LS-U+, LS-M, X-Rider and X-Terrain guises, but we will also post a full price list below so you can choose your own adventure.
The SX range is now $500 more expensive across the board, and it starts at $42,700 with a 1.9-litre engine and two-wheel drive, or $50,700 for four-wheel drive. If you want the bigger 3.0-litre powerplant, it’s $44,700 for the 2WD, or $52,700 for the 4x4.
Then it’s the LS-U, which is big-engine only, and is $54.5k (which is up by $1500, by the way) for the 4x2, and $62.5k (again up $1.5k) for the 4x4. There’s also a LS-U+, which is $65,500 in 4x4.
Next is the LS-M, which is $55,800 (up $500), before the new-for-2024 X-Rider jumps in at $59,500. Both are four-wheel drive only and feature only the big engine.
Finally, there’s the flagship X-Terrain — big engine only, and four-wheel drive as standard — which is $70,500 (up a sizeable $3k), but which is also just $67,990 drive-away, at least for now.
The entry-level SX gets a vinyl floor, cloth seats, powered windows and mirrors, and air-conditioning with rear vents. Tech is handled by a new 8.0-inch central touchscreen with wireless Apple CarPlay and Android Auto, pairing with four speakers, while an also-new 4.2-inch screen sits in the driver’s binnacle. You also get 17-inch steel wheels, automatic wipers and halogen headlights.
Stepping up to LS-M trim gets you new and softer rear suspension, a higher-grade cloth interior treatment, bi-LED headlights and DRLs, 17-inch alloy wheels and body-coloured mirrors, door handles and tailgate handle. If you can spring for this trim, it feels like the sweet spot of the lower-range models.
Next there’s the new X-Rider, which was once was a special edition but now rejoins as a permanent member of the family. It’s all about upping the street credibility, so there’s black gloss on the grille and a black underbody spoiler, as well as black on the rear step bar, the mirrors, door handles and tailgate handle, the B-pillars, the sports bar and on the soft tonneau cover. There are also black 17-inch alloy wheels and dark grey side steps.
Next up is the LS-U, which ups the cabin tech with a new 9.0-inch central screen, but with tactile dials for volume — fixing what was apparently a big complaint about the outgoing D-Max – as well as a new 7.0-inch Driver Display. There’s also keyless entry and push-button start, including a new welcome light that illuminates the interior when you approach, dual-zone climate control and a nicer interior treatment. Outside, there’s a tub liner, silver side steps, chrome on the handles and mirrors and 18-inch alloys.
The LS-U+ then adds leather seats which are heated in the front and eight-way power-adjustable for the driver, and four-way power-adjustable for the front passenger.
Finally, the flagship X-Terrain gets red stitching across its leather interior, remote engine start, a rolling tonneau cover, a unique sport bar, dark grey side steps, mirrors, handles and roof rails, and 18-inch matte-grey alloys wheels.
2024 Isuzu D-MAX Pricing (RRP before on-road costs unless specified)
The Z71 has a 2.8-litre four-cylinder turbo-diesel Duramax engine (147kW at 3600rpm and 500Nm at 2000rpm), six-speed automatic transmission, a part-time 4WD system and a rear limited slip differential.
The D-Max’s powertrains for 2024 remain unchanged, with the choice of a 1.9-litre turbo-diesel four-cylinder engine good for 110kW and 350Nm, or a 3.0-litre unit producing 140kW and 450Nm. They are paired with either a six-speed manual or six-speed automatic, and two- or four-wheel drive, depending on the model.
Our dash display read 7.9L/100km, but we recorded actual fuel consumption on test of 9.7L/100km. It has a 76-litre fuel tank, so expect an approximate driving range of 753km (according to our on-test fuel consumption), factoring in a 30km safety buffer.
On our towing loop, of more than 200km total, the dash was showing 14.5L/100km, but we recorded an actual fuel-consumption figure of 15.5L/100km. Expect an approximate driving range of 460km (according to our on-test fuel consumption), factoring in a 30km safety buffer.
Isuzu reckons you’ll see around 8.0L/100km on the combined cycle with the bigger engine, with fuel use dropping to 6.9L/100km with the 1.9-litre unit fitted.
The 76-litre tank is the same for both engines, meaning a theoretical range of 950km or 1100km.
The Z71 has a steel ladder-frame chassis, double-wishbone front suspension and leaf-spring live rear axle, so it's more aligned with heavy-duty work than smooth on-road performance.
Having said that, the Z71 is quite settled over most surfaces, including highway bitumen and rough back-road backtop, and at most speeds – rather impressive for an unladen ute.
Steering is a bit floaty, with some play in it, and there is noticeable understeer on corners.
The engine is one of the torquiest in the current-day ute mob – only matched by V6 utes – and it delivers that torque quite evenly and smoothly across the rev range. The Duramax turbo-diesel can, however, be noisy, and because of that it seems like it's working hard, though it never feels too stressed, even when towing a caravan that has a caravan with a tare (empty) weight of 2600kg.
There's plenty of life in terms of acceleration with active pedal-feel but, when it comes time to pulling up to a fast stop on front disc and rear drum brakes, the brake pedals are rather spongy.
The six-speed auto is generally spot-on for all duties, although it did occasionally down-shift with an extra violence of action when it didn't really need to.
Ride and handling are pretty good, with its Aussie-tuned suspension (including traditional-ute leaf-springs at the rear) doing a decent job of sorting everything evenly, and it was only ever rattled by very severe bumps, wash-outs, and ruts at lower speeds, i.e. during low-range 4WDing.
The Z71's on-road performance and refinement are generally not as polished as segment leaders, but that's nowhere near a deal-breaker.
Remember, it’s evolution over revolution for the 2024 Isuzu D-Max, so don’t expect the drive experience to be dramatically different.
Instead, the brand says it has focused on fixing some of the complaints surrounding the outgoing model, something Isuzu is pretty open about.
It says they’ve taken feedback from the media, from their customers, and from their big fleet users, and they’ve fed it up their Japanese HQ. And the result of all that is this 2024 update.
Apparently one of the biggest complaints focused on the infotainment screen having no physical buttons, but the new one changes that with its wireless Apple CarPlay and twin USB connection points joined by a physical volume dial. I know that feels a little like you’ve taken a step backwards through time, but when something works, it works.
The’ve also made some key, and worthy, changes to the safety systems, but we will get to those in a moment.
The reality is — and I don’t mean this in an insulting way — that the new D-Max largely drives much like you might expect a top-selling diesel dual-cab to drive.
The torque on offer from both engines, but especially the bigger one, is plentiful, even if the noise of the diesel is an ever-present passenger when you put your foot down, and there is that inescapable truck-like feeling from behind the wheel.
There are some elements that set it apart, though. The steering is smooth and responsive, as is the quick-witted automatic gearbox, and despite us tipping into corners a little faster than we would on our daily commute, there wasn’t much in the way of side-to-side body roll, and no complaints from the rubber.
That might sound like I’m damning the D-Max with faint praise, but that’s not the intention. It’s a comfortable, capable, practical workhorse, and that’s ticking plenty of ute boxes, right?
The bigger-engined D-Max remains a towing powerhouse, too. We pulled some serious weight, and 3.0-litre turbo-diesel made pretty light work of it, with ample torque on offer to keep things moving.
It wouldn’t be the launch of an updated diesel dual-cab without a tour across a tailored off-road course, and Isuzu delivered, specifically to plug the merits of its new Rough Terrain Mode.
Tested back-to-back with the system switched on and off, there does seem to be less slip from the wheels when traversing bumpy, tyre-torturing articulations, with the D-Max just gripping and going. It’s another off-road tick for a ute already very good in the rough stuff.
The Colorado line-up has a five-star ANCAP rating as a result of testing in 2016.
Safety gear includes seven airbags, front and rear parking sensors, a reversing camera, Forward Collision Alert), Lane Departure Warning, a tyre-pressure-monitoring system, Hill Descent Control, Hill Start Assist, Trailer Sway Control and Roll Over Mitigation.
Full credit to Isuzu for equipping the entire D-Max range with the best of its safety equipment, much of which has been overhauled for this generation.
That starts with a new-generation camera that scans the road for cars, pedestrians and cyclists with greater clarity. It also includes a charging plug for an aftermarket dash-cam.
There’s now updated Lane Keep Assist, better programmed to centre in the lane rather than bouncing from edge to edge, bumper bowling style. There’s Rear Cross-Traffic Alert and Brake and Adaptive Cruise Control, too.
That fact that it’s all standard from the entry-level SX is fantastic, and the D-Max range copped the full five-star ANCAP rating when tested in 2020.
Holden offers a five-year, unlimited-kilometre warranty across the Colorado range, with servicing required every 12 months or 12,000km. Capped price servicing applies over seven years/ 84,000km with the average annual cost over three years working out to be $405.
The D-Max is covered by Isuzu’s six-year, 150,000km warranty, and we like the years, but less so the kilometre limits.
There’s five years of capped-price servicing, too. You’ll be visiting the service centre every 12 months or 15,000kms, and each visit will cost you $449 for the first five years, or $2245 in total.
