Toyota HiAce vs Isuzu D-Max

What's the difference?

The HiAce maintains its staggering 50 per cent share of the mid-size commercial van market for numerous compelling reasons including its versatility, as evidenced by the diverse range of Aussie businesses that rely on it. Toyota’s latest suite of safety and other upgrades makes it even better.

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.

Apart from the recent safety upgrades, our LWB test vehicle resolutely adheres to a design that’s been perfected through decades of hard yakka.

Its simple and robust unitary chassis features MacPherson strut front suspension, a leaf-spring live rear axle, rack and pinion steering and (on all automatic variants) four-wheel disc brakes.

The HiAce’s traditional rear-wheel drive layout has an inherent traction advantage over front-wheel drive rivals, particularly when towing and hauling heavy loads on low-grip surfaces.

It also ensures the front wheels can be turned sharply enough for its 3210mm wheelbase to deliver an impressively tight 11.0-metre turning circle. And its 1990mm height also allows access to underground loading docks and multi-storey car parks.

There’s no load-floor liner or cabin bulkhead included as standard equipment, but both are available as Toyota genuine accessories. The use of unpainted plastic bumpers is designed to best withstand the wear and tear often evident in these areas on hard-working vans.

The cabin is spacious and airy, with a neat and functional dash design featuring large and clear instrumentation and (thankfully) physical dials and buttons rather than distracting touchscreens for the main controls that are easy to reach and operate. It’s a commercial van that’s easy to live with.

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You get fairly rugged styling that fits in for both work and play, and the interior is functional, if getting a little outdated.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

With its hefty 2260kg kerb weight and 3300kg GVM, our test vehicle has a 1040kg payload rating. So, it’s a genuine one-tonner and up to 120kg of that can be carried on Toyota’s triple roof-rack set.

The HiAce is also rated to tow up to 1500kg of braked trailer and with its 4800kg GCM rating (or how much weight it can legally carry and tow at the same time) it can carry its maximum payload while towing its maximum trailer weight. So, that’s more than 2.5 tonnes of combined cargo-carrying capacity, which would comfortably meet or exceed most job requirements.

Its cavernous cargo bay, which offers 6.2 cubic metres of load volume, is accessed from either side through sliding doors with 1010mm-wide openings, or through rear barn-doors with 180-degrees opening to allow easy forklift access.

The cargo bay is 2530mm long, 1760mm wide and 1340mm high, with 1268mm between the rear wheel housings allowing up to two standard Aussie pallets or three Euro pallets to be carried, secured by a choice of six load-anchorage points.

An unusual feature is the roof’s full-length internal lining, which we suspect contributes to at least some suppression of tyre noise emanating from the rear-wheel housings. The walls and doors are neatly lined to mid-height and there’s ample internal lighting.

Generous cabin storage includes a bottle-holder and bin in each front door, small bottle/cupholders in the centre and either side of the dash, plus a single glove box. The console between the seats offers another two bottle-holders plus generous internal storage, which is topped by a large hinged lid that can also serve as a storage tray or work desk.

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.

Toyota’s well-proven (1GD-FTV) 2.8-litre, four-cylinder, turbo-diesel produces 130kW of power at 3400rpm and, in auto models like ours, 450Nm of torque between 1600-2400rpm. Its Euro 5 emissions compliance doesn’t require AdBlue, which minimises maintenance and running costs.

The refined six-speed torque converter automatic offers the choice of sequential manual-shifting. Fuel efficiency is optimised with full torque converter lock-up on fourth, fifth and sixth gears, along with overdrive on fifth and sixth to minimise engine rpm when highway driving. The traction advantage of rear-wheel drive is enhanced by an electronically controlled automatic limited-slip diff.

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.

Toyota claims combined cycle (urban/extra-urban) average consumption of 7.8L/100km. Our 328km of testing was conducted with the engine’s auto start/stop function switched off and comprised the usual mix of city, suburban and highway driving, of which about one third was hauling a near-maximum payload.

Our own figure, calculated from fuel bowser and tripmeter readings, was 10.7L/100km. That’s still within the usual 2.0-3.0L/100km discrepancy between official and real-world figures and not bad for a vehicle weighing more than 2.2 tonnes driven mostly in metro settings and hauling more than one tonne during our test. So, based on our real-world consumption, you could expect a driving range of around 650km from its 70-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 driving position is comfortable thanks to a well-sorted combination of supportive seating with power-adjustable lumbar support, a leather-rimmed steering wheel that’s adjustable for height and reach and a large left footrest for extra support.

The standard kerbside sliding door includes a large window, which partly reduces the huge blind spot over the driver’s left shoulder created by the cargo bay’s solid walls.

Fortunately, the HiAce also comes standard with blind-spot monitoring to ensure safe lane-changing on multi-lane roads, while its rear cross-traffic alert and rear-view camera are equally valuable when reversing out of driveways into busy traffic.

The new electric power steering has more noticeable changes in turning weight compared to the more linear hydraulic system it replaces. Its variable-ratio assistance feels even lighter at parking speeds for easier manoeuvrability and becomes increasingly firm and direct as road speeds increase.

Ride quality is reasonably supple when unladen or lightly loaded and the 2.8-litre turbo-diesel, with its sizeable 450Nm of torque, has strong low-rpm response and displays good flexibility in city and suburban driving.

Internal noise levels below 80km/h are acceptable, but like all vans can become intolerable at highway speeds due largely to tyre roar emanating from the rear-wheel housings. So, if you do lots of highway travel, we’d recommend fitting Toyota’s genuine accessory solid bulkhead to insulate the cabin from this noise.

The six-speed auto’s shift calibrations feel like they’re getting the best out of this engine, particularly fuel-efficient highway travel which requires less than 2000rpm to maintain 110km/h. The sequential manual-shifting function can be handy in certain situations, though, like hauling/towing heavy loads in hilly terrain.

To test its GVM rating we forklifted 830kg into the cargo bay, which combined with our crew of two equalled a total payload of 1010kg that was only about 30kg less than its 1040kg limit.

The stout rear leaf-springs only compressed about 30mm, which left more than 60mm of static bump-stop clearance that was more than enough to ensure there was no bottoming-out on our test route.

Its ample torque made light work of hauling this payload in city, suburban and highway driving as well as our 13 per cent gradient, 2.0km-long set climb at 60km/h, which it easily cleared in third gear.

Engine braking on the way down, in a manually-selected second gear, wasn’t as robust but within expectations given the one-tonne-plus payload it was trying to restrain.

We also tested what we safely could of the HiAce’s latest safety upgrades in road use, which all worked as intended. The ‘lane trace assist’ function when using adaptive cruise control was outstanding, as it resolutely kept the vehicle centred in its lane even around curved stretches of multi-lane highway, without the driver needing to intervene.

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.

The HiAce is covered by Toyota's five-year/unlimited km warranty which is in line with competitors like the Ford Transit Custom and Hyundai Staria Load but lags behind the LDV Deliver 7's seven-year term.

Scheduled servicing is a relatively short six months/10,000km interval, whichever occurs first. Capped price for the first 10 scheduled services up to five years/100,000km totals $3650, which is $365 per service or $730 annually.

Toyota currently has 275 dealers across its vast Australian network located in metro, rural and regional areas. Toyota dealerships are also service centres.

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.
