GWM Cannon vs Isuzu D-Max

What's the difference?

It combines big payload and towing capabilities with a standard tray and luxury appointments not usually offered as standard equipment in a single cab-chassis 4x2. And all at a price that matches more basic alternatives from the major players. So, for tradies, farmers or fleets wanting more bang-for-buck style than the usual entry-level workhorse, this could be just what they're looking for.

The new engine makes the D-Max a much more likeable ute than it already was, which is high praise.

It’s smoother and quieter and makes for a more pleasant drive. The added efficiency is a bonus both for your wallet and Isuzu’s emissions credits.

The 3.0-litre engine will probably remain the favourite, but anyone who test drives a 2.2L might even be tempted to opt for the smaller unit. Isuzu sure hopes so.

Our test vehicle rides on a unique 3470mm wheelbase, which is 240mm longer than the 3230mm dimension shared by other Cannon utes.

This is designed to improve load distribution and therefore vehicle dynamics, given the 4x2’s sizeable payload is also unmatched by its siblings (see Practicality). The longer wheelbase results in a 13.9-metre turning circle, which is the largest of the Cannon fleet.

It features double-wishbone/coil-spring front suspension, a leaf-spring live rear axle, four-wheel disc brakes, electric power-assisted steering and under-carriage armour.

The cab’s exterior has an upmarket appearance that’s unusual in this space, matched by an interior which looks more like those found in SUVs and higher-grade dual cabs with faux-leather upholstery, soft-touch surfaces, exposed stitching, contrasting textures and satin chrome highlights throughout.

There’s even a neat line drawing on the passenger-side dash depicting the silhouette of a ute, which highlights its attention to detail.

The look of the D-Max depends on the grade you end up with, but the 2.2-litre SX and X-Rider variants down the lower end of the model-run are still pretty standard-looking utes. Inside and out.

You get fairly rugged styling that fits in for both work and play, and the interior is functional, if getting a little outdated. 

The black trim (and extra features) that comes with the LSM X-Rider as opposed to the SX is worth it if you’re keen to get a 2.2-litre-powered D-Max for the family rather than one for a fleet as it just elevates things slightly.

Inside, it also means nicer cloth, and not having the vinyl flooring looks a little less ‘farm ute’.

Our test vehicle’s relatively light 1900kg kerb weight includes the standard tray. So, its 3050kg GVM results in a substantial 1150kg payload rating that's in addition to the tray, rather than the tray's weight being part of the payload which is usually the case with cab-chassis models.

It’s also rated to tow up to 3200kg of braked trailer, which is 300kg less than the class-benchmark 3500kg its Ranger and D-Max 4x2 rivals can tow, but still ample for most trailering requirements in real-world use.

However, with its 5590kg GCM (or how much it can legally carry and tow at the same time), towing its maximum trailer weight would require a substantial 660kg reduction in payload (from 1150kg to 490kg) to avoid exceeding the GCM limit.

The tray appears to have sturdy construction, complete with a tube-frame front bulkhead that includes a full-width welded mesh insert to protect the rear window from load damage.

According to our tape measure, the tray is internally 1845mm wide and 2580mm long, with hinged and removable drop-sides that stand 260mm tall and feature neat flush-fitting lock mechanisms.

However, there are no internal anchorage points, so all loads must be secured externally using the rope-rails positioned along each side beneath the tray.

Cabin storage includes a large bottle-holder and bin in each door and the driver gets two small nooks on the right side of the dash. There’s also a long and narrow bin provided in the upper left side of the dash, above a usefully sized glovebox.

The centre console has a pad that’s ideal for storing a phone, plus two USB-A ports and a 12v socket. There’s also buttons for controlling other 12v accessories, along with two cupholders and a lidded box at the rear that's usefully deep with an internal vent to control temps for drinks and food. The box lid is also nicely padded to serve as a driver’s elbow rest.

The D-Max remains straight-forward inside, given nothing has changed with the update aside from the 2.2-litre engine and the addition of stop-start - there’s a button for that now.

The interior and usability of the D-Max, especially in the lower-end variants where the 2.2L engine is available, is focused on the basics.

Tech remains at a relative entry point, where the 8.0-inch screen and its software feel outdated but do everything you need. Plus of course there’s the phone mirroring workaround.

The D-Max is comfortable and spacious enough, there’s also physical buttons for everything including media and climate settings, and adjustability in terms of the seating position means not needing to reach.

In dual-cab versions, there’s enough space for an adult to sit in the second row behind another adult, so the D-Max also holds its own as a family hauler. Tick.

Importantly, Isuzu is now able to claim a 3500kg braked towing capacity across the full D-Max range thanks to the new 2.2-litre engine.

Pricing is up across the board for D-Max (and its MU-X sibling) regardless of drivetrain, but we’ll stick to the 2.2-litre variants here to stay on track.

Most of the lower-level D-Max variants are $1500 more than the previous equivalent, and with the manual gearbox dropped, the cheapest grade is the 4x2 single-cab chassis SX with a 2.2L engine at $36,200 before on-roads.

You can get the SX in crew-cab with a chassis or ute back in either 4x2 or 4x4 with a 2.2L engine, which is also available in the LSM X-Rider 4x4. 

That one will set you back $59,500, which is still far from the most expensive D-Max around. That’s still the Blade, with a 3.0-litre engine and 4x4 only, but it’s now $80,900.

Back to the 2.2s, and the SX grade comes with the basics. Cloth upholstery, polyurethane steering wheel and gear selector, vinyl flooring and even halogen lights.

There’s basic air-conditioning, but it does have a HEPA filter, and rear vents for crew-cab models, plus there’s wireless Apple CarPlay and Android Auto, auto wipers, and USB-C power ports as well as a USB-A port.

The central multimedia touchscreen is 8.0 inches, but the driver display is a little 4.2-inch unit between physical dials.

Stepping up to the LSM X-Rider brings with it auto-levelling LED headlights and LED daytime running lights, black styling trim, nicer cloth trim upholstery and gloss black 17-inch alloy wheels.

The rest of the D-Max line-up is 3.0-litre-only, and remains as it was before.

With the rest of the Cannon fleet recently upgrading to a larger 2.4-litre turbo-diesel, its 2.0-litre predecessor is now exclusive to the Premium model grade, producing 120kW of power at 3600rpm and 400Nm of torque between 1500-2500rpm.

It also retains the previous eight-speed torque converter automatic (2.4-litre has a nine-speed unit) offering the choice of sequential manual-shifting using the steering wheel-mounted paddles. And there are three selectable drive modes comprising ‘Normal’ (default), ‘Sport’ and ‘Eco’.

The new 2.2-litre turbo-diesel four-cylinder comes with 120kW and 400Nm, that’s 10kW and 50Nm more than before. Isuzu also says there’s 60 per cent more torque ready from near-idle at 1000rpm.

An eight-speed auto replaces the six-speed, but the brand has also culled the manual options that remained in the line-up.

As ever, that sends power and torque to a part-time 4WD system capable of 2H, 4H and 4L with a rear diff-lock.

GWM claims official combined average consumption of 7.6L/100km but the dash display was showing 9.5 when we stopped to refuel at the completion of our 290km test, which included the usual mix of suburban, city and highway driving of which about one third was hauling its maximum payload.

Our own figure, calculated from fuel bowser and tripmeter readings, was almost identical at 9.7L/100km. That was within the usual 2-3L/100km discrepancy between official claims and real-world consumption and thrifty sub-10L/100km economy for a light commercial in daily urban use.

So, based on our test figure, you could expect a realistic driving range of around 770km from its 78-litre tank.

The biggest advantage for the new drivetrain from Isuzu’s perspective is that it’s more fuel efficient.

The old engine’s 6.9 litres per 100km become 6.6L/100km in the new engine, in part thanks to a new stop-start system. That system is also now on the 3.0-litre engine, where 8.0L per 100km drops to 7.1L.

With its 76L diesel tank capacity, the D-Max should theoretically be able to travel more than 1000km on a single fill, although that comes down to a lot of variables - that 6.6L figure was achieved in almost lab-like conditions.

The GWM Cannon has generous external dimensions which translate to a spacious and airy cabin. In this case, the usually restrictive single cab can easily accommodate taller drivers, given I’m 186cm and found a comfortable driving position.

The door mirrors provide good rearward vision along both sides, but there's no blind-spot monitoring or rear cross-traffic alert. Even so, when carrying a load that blocks the central mirror, the rear camera and parking sensors assist when reversing.

Given our test vehicle’s kerb weight is less than two tonnes, the 2.0-litre turbo-diesel is a better fit in terms of power-to-weight ratio, as it can feel underdone in heavier Cannon ute variants.

As a result, it has livelier response, particularly when operating in its peak torque band between 1500-2500rpm which it does most of the time. We trialled the different drive modes but found the ‘Normal’ default setting an ideal compromise between ‘Sport’ and ‘Eco’ modes.

It has very firm rear suspension, as you’d expect given its big payload rating. This results in a harsh ride over bumps when unladen, as the relatively light weight of the aluminium tray can’t match a heavier steel tray or custom work body in providing the sprung weight needed for a smoother ride. So, ideally it should be carrying a decent load most (if not all) of the time for optimum comfort.

On the highway it only requires about 1800rpm to maintain 110km/h, which is bang in the middle of its peak torque band. At those speeds there is noticeable rear tyre noise along with wind-buffeting from the tray’s bulkhead, but they’re not intrusive enough to require raised voices.

To test its payload rating we forklifted 975kg into the tray, which combined with the weight of the towbar and driver equalled a total payload within 50kg of its 1150kg limit.

The rear leaf-springs compressed 60mm under this weight, which still left about 40mm of static bump-stop clearance that ensured no bottoming-out on our test route.

As expected, the ride quality greatly improved with such a big increase in sprung weight, which is what it’s primarily designed for. And thanks to the extended wheelbase, most of the tray’s load was positioned ahead of the rear axle, which provided ideal weight distribution and good handling stability.

The 2.0-litre drivetrain also performed well on our 13 per cent gradient, 2.0km-long set climb at 60km/h, easily hauling this load to the summit without downshifting lower than fourth gear.

In a manually selected second gear, it also displayed strong retardation when testing engine-braking on the way down, easily staying beneath the posted 60km/h limit until the engine reached 4400rpm on overrun (no redline is displayed) and automatically shifted up a gear.

These engine-protecting calibrations are becoming common in utes and vans, so keeping the revs below that threshold with regular applications of the brake pedal is the best way to share engine and wheel-braking on steep descents with heavy loads.

Our only gripes are, firstly, the intrusive engine clatter between 1000-2000rpm which detracts from its otherwise good performance.

And secondly the emergency lane-keeping assist, with its weird fluctuations in steering weight and aggressive tugs at the wheel when making corrections which are often not justified. Fortunately, this annoying function can be switched off. Unfortunately, you must do it before every drive, which requires accessing the touchscreen each time.

Let’s start with the most important part of the updated D-Max. The new 2.2L is smooth. 

It feels so much more refined physically, but it's also quieter. Paired with the new eight speed, it makes the D-Max a much more likeable ute than it was with the rattly 1.9L.

At the launch, Isuzu had a bunch of MU-Xs to drive (keep an eye on a review coming soon), and the new drivetrain actually suits that big family SUV down to a tee.

The power and efficiency changes are second to how much it changes the characteristics of the thing.

If anything, the D-Max sits in a slightly higher gear than necessary, probably to try and eke as much out of the diesel dual-cab as possible in terms of fuel efficiency, but put your foot down and a more appropriate gear is close-by, and without much fuss.

There's also a relatively good stop-start system. It's not seamless but it's better than some. You take your foot off the brake and the engine rattles back to life, rather than waiting for you to put your foot back down.

The rest of the D-Max’s behaviour is pretty standard ute stuff, as it was before.

The steering is on the light side, but accurate enough even though it has a slightly doughy spot dead-straight. It’s not anything you wouldn’t expect from a ute.

Similarly, the brakes are a bit spongy but predictable, and once you’re used to where the ‘bite’ point is it’s easy to live with.

The suspension is a bit busy, but easy to keep on top of and doesn’t jostle you around. 

Isuzu has done well to include pretty much the full range of safety features across all its variants, with the SX only missing out on rear parking sensors - it still has a camera though, obviously.

Key features like rear cross-traffic alert with braking and adaptive cruise control are standard, plus the D-Max achieved a five star crash safety rating from ANCAP, even though that was under slightly easier testing back in 2020.

The biggest (but only) gripe on-test with the D-Max’s safety gear was its lane-keep during adaptive cruise. There seemed to be a need for the ute to sit close to either the centre line or shoulder during cornering, which led to some discomfort on fast country roads.

It comes with a seven years/unlimited km warranty, plus five years of roadside assistance. Scheduled servicing starts at six months/5000km whichever occurs first, then every 12 months/10,000km. Capped pricing applies to the first five scheduled services up to 54 months/45,000km, which totals $2065 or an average of $413 per service.

GWM currently has a network of 121 dealerships throughout Australia, with expectations of 135 by 2026. They are located in metropolitan and regional areas in every state and territory. And every dealership provides accredited vehicle servicing.

Isuzu’s six-year/150,000km warranty covers the D-Max, which could do without the limited distance, especially for a workhorse.

There’s also five years of flat-rate servicing every 12 months or 15,000km, costing $469 each time.

That’s gone up about $20 per visit since the update, with total cost over the five years at $2345.

There are 164 Isuzu dealers across the country, so finding somewhere to service shouldn’t be a challenge.
