What's the difference?
There’s a fairly big change hiding under the metal of one of Australia’s favourite utes. The Isuzu D-Max has a new 2.2-litre engine, replacing the 1.9-litre unit, and it brings a couple of other things with it.
A bigger engine designed to be more powerful and more efficient can only be a good thing, surely, especially with Isuzu looking down the barrel of stringent emissions laws with only two models in the line-up, both diesel powered.
But is this new 2.2-litre engine any good? Isuzu’s gone to the trouble of a new gearbox and some new tech to go with it, so we check it out to see if it stacks up against the increasingly strong competition.
In 2023 Peugeot commands around 50 per cent of sales in Australia’s small (under 2.5-tonne GVM) commercial van segment with its Partner range, which offers a choice of wheelbase lengths and model grades.
The French marque has recently introduced its first fully electric variant to the Australian market called the e-Partner, even though this van has been on sale in Europe since 2021.
We recently put one to work for a week, which included loading it up to the max, to see how it compares to its petrol-powered sibling.
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.

It’s a lot of money for a small commercial vehicle that’s well into its current model cycle in Europe, falls short on benchmark safety and requires convenient charging infrastructure to minimise inconvenience for owners. However, its emissions-free drivetrain is quiet and competent under load, with a range that should comfortably cater for the daily urban use small van operators typically require. Whether those positives outweigh the negatives, only a potential buyer can decide.
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You get fairly rugged styling that fits in for both work and play, and the interior is functional, if getting a little outdated.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’.
The single electric motor is positioned at the front where it drives the front wheels. The 50kWh lithium-ion battery that provides its energy is located beneath the cargo bay’s load floor to ensure that the total load volume, floor loading heights, etc, are identical to the petrol version.
The same applies to its compact 2975mm wheelbase, 4753mm length, 1921mm width and car park-friendly 1880mm height.
The e-Partner rides on MacPherson strut front suspension and coil-spring trailing-arm rear suspension, with electric power steering and four-wheel disc brakes. Its 11.4-metre turning circle is larger than we expected.
There are unpainted dark grey plastic finishes in all the places where bumps, scrapes and wear usually occur in working vans including hubcaps, bumpers, body side-mouldings, door mirrors and handles. The charging port is located above the left rear wheel.
A sealed metal bulkhead with central window separates the cabin and cargo bay, which minimises tyre noise emanating from the rear-wheel housings and doubles as a cargo barrier.
The cabin architecture, with two bucket seats and wipe-clean vinyl floor, is outwardly the same as the petrol version but the driver’s analogue instrument display has been reconfigured for the electric drivetrain.
This includes continual display of energy consumption levels, comprising 'Eco' (minimum consumption), 'Power' (maximum consumption) and 'Charge' (energy recovery from regenerative braking).
It also displays energy consumption by the cabin heating/air-conditioning and battery charge-level, while the dash’s central touchscreen includes an ‘electric menu’ that monitors live energy flows and consumption statistics plus allows scheduling of delayed charging if required.
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.
The e-Partner’s 1632kg tare weight is about a quarter of a tonne (247kg) heavier than its 1385kg petrol-engine equivalent, largely caused by the lithium-ion battery pack.
So, even though the electric model has more power (100kW vs 96kW) and torque (260Nm vs 230Nm), the battery ensures it has an inferior power-to-weight ratio, with the e-Partner carrying 16.3kg/kW compared to the petrol’s 14.4kg/kW.
The e-Partner’s 753kg payload rating is also 182kg less than its petrol sibling, so be mindful of these differences if payload is important.
The e-Partner is also rated to tow up to 750kg, but given Peugeot does not publish a GCM figure (how much it can legally carry and tow at the same time) we don’t know if it can haul its maximum payload while towing its maximum trailer weight.
The cargo bay, with 3.9 cubic metres of load volume, is a window-free zone accessed by a sliding door on each side and asymmetrical rear barn-doors that open to 180 degrees for optimum loading access.
With its 2167mm length, 1527mm width, 1243mm height and 1229mm between the rear-wheel housings, it can carry one standard Aussie pallet or two Euro pallets held in place by a choice of six load-anchorage points.
The cargo bay is lined to mid-height and there’s protective mesh over the bulkhead window. However, the bulkhead protrudes into the sliding door openings given the need to allow sufficient cabin space for the seat backrests.
There’s also no load-floor protection provided as standard, so to avoid scratches and dents we’d recommend fitting a floor-liner like the thick rubber one fitted to our test vehicle.
Cabin storage includes a full-width shelf above the windscreen and bins in the base of each door. The dash offers small bottle/cupholders on each side plus a lidded upper glove box and open storage on the passenger side.
The dash extension, where the gear-selector and electronic handbrake reside, offers more open storage as does the floor-mounted centre console.
Our criticisms include the lack of a dedicated storage place for the charging cable, which is supplied in a zip-up vinyl bag.
Although it was sitting on the passenger floor when we collected the vehicle, it was difficult to find a secure place to store it with a passenger aboard. It ended up unsecured in the cargo bay.
The rear barn-doors also do not have any stays to keep them open when positioned at 180 degrees.
As a result, the slightest breeze swings them shut.
And due to the lack of any dedicated bottle-holders in the front door bins, bottles tend to topple onto their sides and can be difficult to extract when driving.
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.
Our test vehicle is available in only one specification, based on the ‘Pro Long Auto’ which means it’s the more work-focused ‘Pro’ model grade with long wheelbase and automatic, which in this application is a single-speed transmission.
With a 100kW/260Nm single electric motor and 50kWh lithium-ion battery, it has an eye-opening list price of $59,990, plus on-road costs.
That represents a substantial 56 per cent increase over its petrol-powered equivalent ($38,388) and optional metallic paint like ours adds $690.
However, the e-Partner has more power and torque with zero drivetrain emissions. It also comes standard with work-focused 16-inch steel wheels and 215/65R16 Michelin tyres with a full-size spare, a toggle-style gear selector, electric parking brake, reversing camera, two-way adjustable leather-rimmed steering wheel, 12-volt accessory socket and USB port plus a four-speaker multimedia system with 8.0-inch touchscreen, digital radio and multiple connectivity including Apple and Android devices.
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.
The single electric motor and 50kWh lithium-ion battery combination produces 100kW of power and 260Nm of instant torque.
It also offers three switchable drive modes including Eco (60kW, 190Nm) for minimal performance and energy use, Normal (80kW, 210Nm) which is a happy medium for everyday use and Power (100kW, 260Nm) for maximum performance when hauling heavy loads.
The gear-selector controls Park, Reverse, Neutral, Drive and Brake functions. There's also a button marked B which engages regenerative braking for optimum battery top-ups when driving.
The Mode 3 Type 2 wall-box/public station charging cable is supplied as standard, but buyers can also purchase a domestic wall socket cable for home-charging.
Quickest charge time from 0-80 per cent is 30 minutes using a 100kW DC charger while a 0-100 per cent charge using a single-phase wall-box (7.4kW) takes about 7.5 hours.
Home-charging from 0-100 per cent using a domestic wall socket (2.3kW) takes about 24 hours.
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.
Peugeot claims an official WLTP driving range of 258km. The dash display was showing a projected driving range of 280km when we collected the vehicle.
A few days later when we stopped to top-up the battery at a public charging station, after 135km of unladen city and suburban driving, it was displaying average consumption of 20.4kWh/100km.
When charging was completed, the dash display was claiming 270km of driving range. This had dropped to 194km the following day when we stopped to load the vehicle for our GVM test. Average consumption had also dropped to 19.0kWh/100km.
We then drove 52km with a heavy payload in busy traffic, during which consumption dropped again to 18.8kWh/100km with regular switching between the drive modes.
After unloading and then returning the vehicle to Peugeot, there was still 96km of range remaining and energy consumption had dropped again to 18.4kWh/100km.
So, we covered a total of 271km during our test, of which about one quarter was with a heavy payload.
So, based on its lowest consumption figure, Peugeot’s claimed 258km range in real world driving conditions is pretty accurate by our measure.
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.
It has a comfortable driving position thanks to a reasonably spacious cabin, two-way adjustable steering wheel, left footrest and fold-down inboard armrest.
However, the base cushion feels a tad short for proper upper-thigh support and does not have rake adjustment.
The flat top of the rectangular steering wheel provides a clear view of the instrument display while the flat bottom allows ample driver clearance.
The electric motor with its muted hum delivers a liquid-like flow of acceleration that’s different to a petrol engine.
The lack of engine noise also makes other sounds more prominent, including tyre roar on coarse bitumen surfaces and thumps from the rear suspension over larger bumps.
The extra battery weight is not a noticeable hindrance in stop-start traffic, given the instant torque of the electric motor.
Its location under the load floor also contributes to a low centre of gravity which makes the e-Partner feel well-planted on the road. Even so, it takes a leisurely 11.2 seconds to accelerate from 0-100km/h.
To test its payload rating we forklifted 650kg into the cargo bay which with driver was just under its 753kg limit. The rear suspension compressed 70mm, but there was no bottoming-out over bumps due to large rubber cones positioned inside the coil springs that assist in supporting heavy loads.
We covered more than 50km with this weight in city and suburban driving and its performance was good in all modes including the energy-saving Eco. Energy consumption did not spike as expected.
Our only gripes from a driver’s perspective are the absence of blind-spot monitoring and rear cross-traffic alert, which should be mandatory in all solid-walled vans given the huge blind-spot over the driver’s left shoulder. Relying only on the relatively small passenger door mirror is potentially hazardous.
The other is the cruise control stalk located on the steering column, which is hidden from view by the steering wheel arm. Therefore, it must be operated purely by feel, which can be fiddly and distracting when driving.
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.
Only four from a possible five ANCAP stars for the e-Partner (achieved 2018) and the lack of blind-spot monitoring, rear cross-traffic alert and adaptive cruise control, etc, highlight a safety menu in need of updating.
Even so, it does have front, side and curtain airbags for driver and passenger plus AEB, lane-keeping, audible low-speed pedestrian alert and tyre under-inflation warning.
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.
Warranty is five years/200,000km plus eight years/160,000km for the battery. There are also three-year paintwork and 12-year corrosion warranties.
Scheduled servicing is every 12 months/25,000km, whichever occurs first.
The pre-paid service plan price of $1000 covers the first five scheduled services, or just $200 per service.
