BYD Shark 6 vs Isuzu D-Max

What's the difference?

The Shark 6 breaks new ground with its PHEV technology and impresses with not only its whisper-quiet and rapid acceleration but also engaging chassis dynamics, build quality, fuel economy and generous standard equipment for a compelling price. However, its modest payload and tow ratings may be deal-breakers for some tradies and recreational buyers with bigger loads to haul.

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.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

Our test vehicle rides on a 3260mm wheelbase and is 5457mm long, 1971mm wide and 1925mm high, so it’s in the same ballpark as a Ford Ranger 4x4 dual cab ute.

The Shark 6 features traditional body-on-frame truck chassis design, double-wishbone coil-spring front and rear suspension, rack-and-pinion steering and four-wheel disc brakes.

It also has a compact 11.0-metre turning circle and its off-road credentials include 230mm of unladen ground clearance, 700mm wading depth and 31 degrees approach/17 degrees ramp-over/19.3 degrees departure angles. A large metal bash-plate protects the underside.

Looks are subjective of course and even though there’s too much external black plastic for our liking, we reckon it still passes the pub test on styling with its chunky and purposeful appearance.

The bold grille and headlight design appears to draw inspiration from full-size US pick-ups, but with a ‘technical’ look consistent with its high-tech powertrain.

The predominantly grey interior has a high-quality finish and looks good. It also appears to draw inspiration from rivals, in this case the Ranger Raptor with its contrasting bright red air-vent/cupholder surrounds and exposed stitching along numerous seams.

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You get fairly rugged styling that fits in for both work and play, and the interior is functional, if getting a little outdated.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 2710kg kerb weight and 3500kg GVM, the Shark 6 has a 790kg payload rating which is less than some turbo-diesel rivals.

It’s also rated to tow up to 2500kg of braked trailer which is 1000kg less than the category benchmark. And BYD does not publish a GCM (Gross Combination Mass) rating, so we don’t know how much weight the Shark 6 can legally carry and tow at the same time.

The load tub is almost square with its 1520mm length and 1500mm width. And with 1224mm between the rear-wheel housings, it can carry either Aussie or Euro pallets. Its 517mm depth results in 1.2 cubic metres of total load volume.

There are six load-anchorage points but those located in the sidewalls at the front and centre of the tub are too high for securing low-profile loads. Anchorage points located near floor-level are preferable, as they can secure loads of all heights.

The tub’s internal surfaces are protected by a spray-in liner and there’s bright internal lighting and a hydraulic strut to ease tailgate operation.

Seating for the driver and front passenger is spacious and comfortable. The rear bench seat shares similar qualities, given I’m 186cm tall and when seated behind the driver’s seat in my position I still have ample kneeroom.

Rear seat passengers also enjoy sufficient headroom, even for tall people seated in the least popular central position who also have a nice flat floor given the absence of a transmission tunnel. However, shoulder room for adults sitting three-abreast is tight and best limited to short drives.

Cabin storage for front seat occupants includes a large-bottle holder and bin in each front door, overhead glasses holder plus a dash storage shelf and glove box on the passenger side.

The centre console has two small-bottle/cupholders in the centre and a lidded box at the back.

Rear passengers also get a large-bottle holder and bin in each door, plus pockets on the rear of both front seat backrests and a fold-down centre armrest with two small-bottle/cup-holders.

The bench seat’s base cushion can be raised and stored vertically if more internal luggage space is required, but there’s no under-floor storage.

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.

The Shark 6’s hybrid drivetrain with permanent all-wheel drive includes two electric motors, with the front motor producing up to 170kW/310Nm driving the front wheels. The rear motor produces up to 150kW/340Nm and drives the rears.

These motors are teamed with a 1.5-litre turbocharged four-cylinder petrol engine producing up to 135kW/260Nm, which serves dual roles as a generator to maintain charge in the 29.58kWh lithium-ion battery (in addition to regenerative braking) and to assist with driving the front wheels as required. It can also perform both roles simultaneously.

The combined output of electric motors/petrol engine is up to 321kW and 650Nm. There are also three selectable drive modes comprising Eco, Normal and Sport, plus different terrain settings to optimise performance in Mud/Sand/Snow/Mountain.

The plug-in battery can be charged using either the AC (7.0kW) or DC (55kW) ports. Cables for both were supplied with our test vehicle and stored in a carry bag behind the rear seat.

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.

BYD claims combined average fuel consumption for the petrol engine as low as 2.0L/100km with 25-100 per cent SoC (State of Charge) which spikes to 7.9L/100km when SoC drops below 25 per cent (see Driving).

BYD also claims an NEDC battery-only driving range of up to 100km (with 25-100 per cent SoC) and up to 800km when combined with the petrol engine in hybrid mode.

We covered 522km during our test which was a mix of city, suburban and regional roads plus some highway driving, of which about one fifth of that distance was hauling a near-maximum payload.

At the completion of our test, the Shark 6’s onboard computer claimed average petrol consumption of 6.6L/100km with 204km of range remaining, which suggests a real-world driving range of at least 700km is credible from its 60-litre petrol 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 seating is comfortable and supportive and the driving experience is enhanced by the head up display, large left footrest and thick-rimmed leather wheel.

It’s quiet to drive and the ride quality is outstanding, with refined and disciplined suspension tuning combined with responsive steering and braking. It all adds up to handling agility on winding mountain roads that belies the fact it’s a high-riding 2.7-tonne ute.

Rapid acceleration from standing starts (BYD claims 0-100km/h in just 5.7sec) is also effective in masking its bulk, as instant torque from the dual electric motors gets it rushing towards triple-digit speeds with unrelenting ease, regardless of gradient.

We did most of our test in the ‘Normal’ (default) drive mode, as it provides a happy medium between the heightened response of ‘Sport’ and the slightly subdued ‘Eco’ modes.

To test its GVM rating, we loaded 650kg into the load tub which with driver equalled a 750kg payload that was only about 40kg less than its legal limit. The independent rear suspension compressed about 60mm, but there was no bottoming-out detected as it competently hauled this load on our test route.

Although the ‘Energy Manager’ on the touchscreen allows drivers to pre-set a minimum SoC between 25-70 per cent, we didn’t enter any setting as we wanted to see how the hybrid system performed without these inputs.

Fact is, it did not allow the SoC to drop below 20 per cent, even during highway driving when there was minimal charging assistance available from regenerative braking.

As displayed live on the energy manager, the petrol engine maintained the battery charge needed to feed the electric motors while also providing intermittent drive to the front wheels as required.

At times the little 1.5-litre turbo engine sounded like it was working very hard doing this, but it did prove effective in performing these dual roles.

The hybrid system also produces minimal engine-braking (even with maximum regenerative braking) which is an important consideration if you regularly carry and/or tow heavy loads, particularly in hilly terrain.

With a traditional turbo-diesel and multi-speed transmission, a low gear can be manually selected to allow the engine on overrun to assist the brakes in restraining loads on steep descents. However, with its single-speed transmission and small petrol engine, the Shark 6 must rely on brakes alone.

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 Shark 6 is covered by BYD's six-year/150,000km warranty and an eight-year/160,000km battery warranty.

Scheduled servicing is every 12 months/20,000km whichever occurs first. Capped-pricing for the first six scheduled services totals $2945 or an average of $490 per year.

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.
