What's the difference?
The arrival of the GWM Tank 500 Ultra PHEV is noteworthy because it’s the first plug-in hybrid Tank model in Australia.
It’s also a major event for the Aussie adventure-travel community because it’s a plug-in hybrid 4WD with five seats, high- and low-range gearing, and a front, centre and rear diff lock.
The Tank 500 PHEV gets more power and torque than its hybrid stablemate, offers about 120km electric-only driving range (listed), and it can be used as a 6kW mobile power station (V2L) at your campsite. Towing remains at 3000kg.
There’s a lot in this Tank’s favour: it’s a body-on-ladder-frame chassis large 4WD with a packed standard features list and real off-road adventure potential.
All of that – and more – for under $80 grand.
But does the plug-in set-up add anything substantial in terms of daily driveability or does it simply make this Tank an $80,000 camp-site generator?
Read on.
Large SUVs like the Toyota LandCruiser, Nissan Patrol and Land Rover Defender have dominated in Australia for decades now, however there’s now something new to shake up the segment.
BYD’s luxury spin-off brand, Denza, has launched in Australia with two plug-in hybrid (PHEV) off-road SUVs. The B8, which is the larger of the two, is on test here.
With three rows of seating, a bucketload of standard equipment and a jaw-dropping starting price, the B8 is being pitched as a PHEV alternative to the currently diesel-only LandCruiser 300 Series among other more premium alternatives like the Land Rover Discovery and Mercedes-Benz GLS.
We’ve already driven the B8 over in China and this is the first time we’re getting to test it out on Australian roads, so let’s see how it stacks up.
The GWM Tank 500 Ultra PHEV is an impressive five-seat 4WD wagon. It’s reasonably nice to drive, it’s comfortable and it’s a capable 4WD. These vehicles keep improving and are increasingly stacked with characteristics to like.
There are still glaring range-specific issues with some of its driver-assist tech and its plug-in hybrid set-up doesn’t offer the fuel economy you’d hope for. At least not under real-world testing conditions. But the Tank 500 is packed with features and represents decent value-for-money when cross-shopped against the likes of its stablemate the regular hybrid, or the Prado and Everest.
The Denza B8 is an incredibly luxurious car that has a lot going for it, including three rows of seating, a 3.5-tonne braked towing capacity and an eye-popping price tag, but it's held back by its overall heft and cumbersome ride.
If you don’t absolutely need the third row of seating, the smaller B5 is arguably the better pick and while it’s also not perfect, it’s a very compelling package and you’ll be saving thousands of dollars in the process.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.
In terms of dimensions, the Tank 500 Hi4-T PHEV is 5078mm long (with a 2850mm wheelbase), 1934mm wide and 1905mm high. It has a listed kerb weight of 2820kg, so it’s not an insubstantial vehicle.
There are plenty of old-school 4WD design cues in the Tank 500’s appearance. It’s mostly chunky and straight up and down, with some softer curves here and there as concessions to contemporary styling.
It's clear to see where the GWM Tank 500 takes its cues from – most of the current crop of popular 4WD wagons, such as the Toyota LandCruiser 300 Series.
The Tank 500 is a large vehicle straddling that line between large and extra-large 4WD wagons. It is longer than any 300 Series, but it’s narrower and shorter.
It has a sunroof, roof rails, electric side steps (that extend when doors are opened and retract when doors are shut) and 18-inch alloy wheels.
The interior is well laid-out and functional with some understated class to it. There are soft-touch surfaces and genuine Nappa leather seating throughout.
There’s no way around it, the Denza B8 is a big car. It’s almost 5.2 metres long which makes it larger than a LandCruiser 300 Series and more in line with the likes of the Land Rover Defender 130.
It looks quite boxy and tough on the outside, though it doesn’t have any features that define it specifically as a Denza beyond the inconspicuous badging. There are many angles that are reminiscent of the aforementioned Defender.
The body lines look crisper than the smaller B5, as does the semi closed-off grille and LED light script that connect the big LED headlights.
Unlike the B5, the tailgate-mounted spare wheel is much more prominent in the B8 and this therefore exaggerates its heft, not in a good way.
Inside, it’s luxurious and high-end with lots of visual appeal. I particularly like the amount of soft-touch finishes around the cabin and the overall lack of glossy piano black.
While luxurious, there’s also a rugged edge to the interior. This is most present in the large grab handles which you do need to use when getting in and out.
The amount of physical buttons and switches inside is a nice touch as you don’t need to relate on the touchscreen all the time. The fact the gear shift lever rises up when you turn on the car also adds to the special, luxurious feel.
This Tank 500 has five seats because the two at the very rear have been removed to accommodate the hybrid battery.
The front seats are Nappa leather, power-adjustable (eight-way for the driver, six-way for the front passenger), as well as being ventilated with massage and memory functions.
The three-position second row – set up in a 60/40 split-folding configuration – breaks the usual 4WD wagon second-row seat tradition of being fine but not fantastic. The second-row set-up in this Tank is a first-class-cabin-style back seat with a flip-down control console (which includes air-con controls) instead of a basic centre armrest.
As mentioned there is no third row in this Tank 500 because of its underfloor battery.
Up front, the 14.6-inch multimedia screen (with wireless Apple CarPlay and Android Auto) dominates the dash. It's generally easy enough to use, although I had difficulty getting my iPhone hooked up to the system and the cabin set-up remains clunky and counter-intuitive in its operation.
The cabin has wireless charging, front and rear USB ports, as well as 12V and 220V power outlets.
The second row folds away to expand the rear storage capacity. Cargo volume is a listed 640 litres when all seats are in use and 1400 litres when the second row is stowed away.
The rear cargo area has tie-down points and a cargo slide cover.
Hopping into the B8 you need to acquaint yourself with how the flush door handles operate. Generally they pop open when you unlock the car but sometimes they can be a little delayed.
Also inside the car there are electronic door release buttons which are nowhere near as intuitive as regular door pull handles. Sure you’d likely get used to this over time but you’ll need to explain it to new passengers all the time.
The seats in Chinese cars usually look nice but aren’t that comfortable or supportive for long-distance journeys. The B8’s are the opposite, offering great support and almost limitless adjustability. Adding to this is the standard heating, ventilation and massage functions.
Ahead of the driver is a leather-wrapped steering wheel which feels nice and has plenty of physical buttons with a tactile click when pressed.
Behind this, the digital instrument cluster is clear and high-resolution and offers a number of different layouts and informative pages you can cycle through. This allows you to customise the display.
In the centre of the dashboard is the mammoth 17.3-inch touchscreen multimedia system which is the largest central screen I have seen in a car to date. It’s a big screen for a big car and Apple CarPlay satisfyingly takes up the entire screen.
Thankfully, the screen is snappy and has a native user interface that is easy to navigate around without getting lost. I particularly like the swipe-down control centre menu that allows you to change key settings without diving into sub-menus.
My only hassle with the screen is I struggle to reach the far left-hand side due to its overall size. Perhaps a trackpad would solve this.
As I noted previously, the amount of physical switchgear around the cabin makes adjusting key functions easy. Examples include physical buttons to change the drive mode, activate the surround-view camera, adjust the suspension position and switch between EV and hybrid driving.
In terms of storage up front there are two non-ventilated 50W wireless phone chargers, two cupholders with adjustable depths, a shallow storage section under the centre console, plus a fridge/hotbox under the centre armrest.
Moving to the second row and the luxury continues. The seven-seat model features a three-seat bench that three people can easily fit across as the floor is flat, whereas the six-seat model gets uber-plush captain’s chairs.
Regardless of variant, there’s plenty of room in the second row, even for adults.
Second-row amenities include a small screen on the back of the centre console box that allows you to change the climate control and change the seat heating/ventilation, among other functions.
There’s also a button that opens the fridge/coolbox so the second-row passengers can access it. This is a nifty touch though you’d want to make sure small fingers don’t get caught as the anti-pinch function isn’t the strongest.
A feature that’s unique to the six-seat version is a massaging function on the second-row captain’s chairs. This is a very cool touch that no other SUV at this price point offers.
Accessing the third row in the six-seat version is rather easy as you only need to walk down between the captain’s chairs. It’s also simple enough in the seven-seat version as long as you access it from the kerb side.
Third-row space is decent for adults, but this shouldn’t be surprising as the B8 is such a hulking vehicle. The backrests also recline allowing for extra comfort. Amenities include air vents in the headliner, USB-C ports and scattered storage. It’s enough for seats that will likely only get occasional use.
Around the back the B8 has a side-hinged tailgate which is a little problematic as you need to allow space for it to open up in parking spaces. This is hard when the car is already 5.2m long…
With all three rows upright there is 147L of boot space, which is fine, but this expands to a much more usable 920L with the third row folded.
The boot space is square and usable, though there is a large load lip which is body-coloured and would easily get scratched if you drop something on it. Not the best in a family-oriented vehicle.
Boot-related amenities include buttons to electronically fold the second and third row seats and lower the suspension to make things easier to load into the boot, a 12V socket, scattered hooks, as well as a small underfloor section to store the changing cables.
Although it stands out like a sore thumb, it’s great to have a full-size spare wheel on the back of the tailgate. This is very helpful in the unlikely and unfortunate event you get a puncture.
The GWM Tank 500 PHEV is only available in high-spec Ultra trim and has a listed drive-away price of $78,990.
Standard features in the Ultra include a 14.6-inch multimedia touchscreen (with wireless Apple CarPlay and Android Auto), three-zone climate control, 18-inch alloy wheels, electric side steps, a 360-degree view monitor plus 'clear chassis view', auto parking assist, auto reversing assistance, lane departure warning and lane keep assist, all-terrain driving modes and an electronic rear diff lock.
Worth noting the Tank 500’s 37.11kWh battery supports Vehicle-to-Load (V2L) functionality, which means you can power your camping gear (lights, fridge etc). It offers up to 6.0kW of off-grid power, according to GWM.
'Marble White' paint is standard. Metallic paint, including 'Crystal Black' ($495), 'Dune Gold' ($595), and 'Onyx Silver' ($595) costs extra.
The 2026 Denza B8 line-up starts at $91,000, before on-road costs, for the seven-seat version, which is strategically just under the Luxury Car Tax (LCT) threshold, whereas the flagship six-seat version is $97,990, before on-road costs.
Despite nearing $100K, this notably undercuts key rivals like the Toyota LandCruiser 300 Series and Land Rover Defender by a considerable margin, especially once you take the level of standard equipment into account.
The B8’s closest rival is currently the slightly smaller GWM Tank 500 PHEV which is priced even more competitively at $77,990, drive-away.
As a base there are 20-inch alloy wheels, adaptive LED headlights, soft-close doors, a 12.3-inch digital instrument cluster, a 17.3-inch touchscreen multimedia system, 18-speaker Devialet sound system, tri-zone climate control, leather upholstery, plus heated and ventilated seats in the first and second row.
Moving up to the six-seat version brings second-row captain’s chairs with adjustable legrests and a massage function, as well as a digital rear-view mirror, head-up display and Nappa leather upholstery.
This amount of standard equipment in a car that’s under $100K is wild and should definitely be enough to put in your consideration list if you’re after a big, three-row SUV. The smaller B5 offers similar levels of specification but goes without the third row.
Every Tank 500 Hi4-T PHEV has a 2.0-litre turbo-petrol engine, a 37.11kWh lithium-ion battery and an electric motor. And that combination produces a total* of 300kW and 750Nm.
* Electric motor 120kW, petrol engine 180kW at 6000rpm. Motor 400Nm, engine 380Nm at 1700-4000rpm.
This system is mostly seamless in operation but as for GWM’s claims that it delivers “outstanding efficiency, performance, and refinement smooth, responsive take-offs, strong acceleration, and exceptional fuel savings - while ensuring minimal noise and maximum driving confidence”. Well, let’s just say this Tank 500 gets off the mark well for a large 4WD but the prompting requires a heavy right foot.
It is generally quiet and comfortable and yields a smooth driving experience. And as for fuel saving, flick your eyes down to ‘Efficiency’ to see how it did on this test.
This Tank 500 has a nine-speed automatic transmission, low- and high-range 4WD gearing, as well as a front, centre and rear diff lock.
Power comes from a plug-in hybrid set-up combining dual electric motors and a 2.0-litre turbo-petrol four-cylinder engine.
Total system outputs are a meaty 425kW and 760Nm. They need to be, as the B8 has a kerb weight of 3.3 tonnes. Despite this, Denza claims it can still do the 0-100km/h sprint in just 4.8 seconds.
Power is sent to all four wheels with a rear mechanical diff lock as standard across the line-up. A front diff lock is only offered on the six-seat version.
What’s most surprising about this big beast is it offers a segment-meeting 3500kg braked towing capacity. It also has up to 700kg of payload, depending on the variant.
Official fuel consumption is 2.1L/100km on a combined cycle on regular unleaded fuel (91) with low-charge consumption at 8.4L/100km. For reference, low-charge fuel consumption on this test was 10.2L/100km as recorded. Okay, but not a particularly compelling result.
The Tank 500 has a 70-litre fuel tank so, going by those fuel figures, you could reasonably expect a driving range of about 686km out of a full tank.
Feeding the dual electric motors is a 36.8kWh lithium iron phosphate (LFP) battery. Denza claims it allows for an electric range of 115km, according to NEDC testing.
The battery can also be used as a power source for appliances using vehicle-to-load (V2L) functionality at rates up to 6.6kW.
AC charging is offered at rates up to 11kW, whereas DC fast-charging is offered at rates up to 120kW.
Additionally, there’s a 91L fuel tank. Denza claims this allows the B8 to have a total range of 1040km (NEDC).
Fuel consumption depends on how often you charge the battery. Denza claims the B8 will use 2.0L/100km from 100 to 25 per cent battery charge and 9.9L/100km under 25 per cent battery charge, both according to NEDC testing. Regardless, this is better than all similarly sized petrol- or diesel-powered SUVs.
The Tank 500 Hi4-T PHEV is decent on road – and that’s good news for anyone thinking about buying this large 4WD.
It has more power and torque than its hybrid stablemate (300kW/750Nm vs 255kW/648Nm) for general day-to-day drivability while it retains all of the regular hybrid’s positive driving characteristics and few of the negatives.
This Tank 500’s turbocharged petrol engine and the electric motor work seamlessly together, with no discernible clunking or shifting between systems in the powertrain.
This is a big, heavy four-wheel drive – even heavier in this plug-in hybrid form than the regular hybrid because of this vehicle’s battery. But it is nicely settled and composed because of that weight.
This flip side is the extra heft on-board means there is some body-roll to this vehicle. It’s noticeable, but not a deal-breaker.
On highways, sealed surfaces or well-maintained bush tracks the Tank 500 is quite impressive. It’s settled, controlled and quite nice to drive.
Overall, this Tank 500’s suspension – double wishbone independent with coil springs at the front, and multi-link live axle with coil springs at the rear – is firm. There has been talk of it having been retuned for Australian conditions, but it remains stiff and jittery at pace, especially through backcountry bitumen in poor condition and lightly corrugated dirt roads. However, GWM informs me that the suspension set-up will undergo more retuning for Australian conditions and those changes will be incorporated into 2026 production vehicles.
Besides that, the engine, electric motor and transmission work quite well together. It is a reasonably smooth 4WD wagon to drive.
There are, however, glaring issues with the driver-assist tech, which is quite annoying in its operation. It’s either very jarring or intrusive in its application (example: adaptive cruise control braking way too early), or bloody annoying/dangerous (example: road-sign recognition abruptly tried to cut my speed from 100km/h to 40km/h because it registered the school zone sign off to the side of the highway. At the time it was outside school drop-off and pick-up times anyway.).
You can switch off the driver-assist features every time you start up, but the system resets and defaults to being annoying again when you switch off.
When it comes to 4WDing though, the good news returns.
This hybrid retains all of the regular Tank 500’s 4WD mechanicals, including the (BorgWarner-sourced) transfer case with high- and low-range 4WD, and it offers up plenty of torque across a decent spread of revs.
The off-road traction control system is suitably dialled in, hill descent control is effective, keeping you to a nice controlled low speed and there’s low-speed cruise control or the equivalent that keeps the vehicle to a controlled pace across varying terrain.
Not forgetting, the Tank 500 is triple locked – front, centre and rear diff locks – so there are few excuses to not be able to crawl over most off-road obstacles.
However, the tyres on this vehicle (Giti Xross HT71 SUV - 265/60R18) aren't up to scratch when it comes to off-roading beyond anything other than well-maintained tracks in the dry. The Tank 500 as is well suited, straight out of the dealership, for light to moderate off-roading. But if you swap in a decent set of aggressive all-terrain tyres the Tank 500 will be able to more comfortably take on more challenging terrain.
But it's capable of climbing. I took on a 30-35 degree incline of rock steps and the Tank 500 did it easily and comfortably on its standard highway tyres.
Most of the plug-in hybrid Tank’s off-roading characteristics check out. Approach, ramp over and departure angles are as per the regular hybrid Tank 500 (30, 22.5 and 24 degrees) and wading depth is a listed 800mm although the country was so dry at our proving ground that I never had the chance to test that claim.
Ground clearance on the Tank 500 Hi4-T PHEV is listed as 213mm (it’s 224mm in the normal hybrid) but that doesn't negatively impact this vehicle's off-roading capability if you drive it with control and consideration.
It is big, so it can be a little bit tricky to steer around, especially when the track becomes tighter and the obstacles become a bit more cheeky, but generally this can be driven very safely and with the utmost control through a lot of tricky four-wheel driving challenges.
It's not as polished in its off-road performance as something like the Toyota Prado or Ford Everest, but it does the job and there's a bit of a gruff edge to it, which some people might consider part of its charm.
As mentioned, the Tank 500’s 37.11kWh battery supports Vehicle-to-Load (V2L) functionality, which in theory means you’ll be able to power your camp-site (lights, fridge etc), but I’ll reserve final judgement on this set-up until I have the opportunity to test it over a long weekend with several appliances drawing power at the same time.
If you’re thinking about using this Tank PHEV as an adventure touring vehicle then it’s handy to know its payload is listed as 610kg, while it’s noted as 790kg in the Tank 500 HEV. Throw two adults, two teenagers, a dog, and camping gear in and you’ll hit that 610kg mark in no time.
The Tank 500 is rated to tow a 750kg unbraked trailer and 3000kg braked. Gross vehicle mass is 3430kg and gross combined mass is 6430kg.
Behind the wheel, the Denza B8 primarily acts as an electric vehicle (EV), meaning it’s largely quiet inside the cabin when driving around normally.
Once the battery charge gets down lower, the petrol engine typically switches on to top up the battery. It largely acts as a generator and a lot of the time you can’t tell whether it’s on or off.
You’ll likely only notice it if you floor the accelerator or go up a steeper hill. Even then the engine largely stays quiet and in the background.
When the battery charge gets down low enough and you gun it, the petrol engine can directly power the front wheels. This is rare, though, because the car leaves at least 25 per cent battery charge in reserve.
With 425kW and 760Nm thanks to the dual electric motors and 2.0-litre turbo-petrol engine, the B8 is far from slow. In fact, for a 3.3-tonne beast it absolutely hauls thanks to the instantaneous torque the electric motors provide.
However in the standard drive mode there is a noticeable input lag from when you push the accelerator pedal hard and when the car starts accelerating. This is reduced in the 'Sport' drive mode.
Although the B8 may produce lots of power and torque, it feels its weight. When you accelerate hard it pitches back dramatically, much like the Jeep Grand Cherokee. It’s much more pronounced than in the smaller B5, but still smile-inducing.
As standard, the B8 line-up gets an adaptive hydraulic suspension system that is claimed to be able to self-level the car. Despite this, the B8 gets a considerable amount of body roll regardless of which drive mode you select.
Many Chinese cars have floaty, comfort-oriented suspension tunes over firmer and a more dynamic-feeling ride, and the B8 is no exception. It feels like a 3300kg+ SUV.
The kicker is, like many body-on-frame vehicles, the ride gets busy on harsher roads with more frequent bumps. As a passenger you get jostled about in the cabin.
The steering tries to disguise the overall heft of this SUV but as a result it can feel overly assisted and vague at certain points. Depending on the drive it either artificially adds or reduces resistance.
Unlike the related BYD Shark 6, the B8 gets diff locks and a low-range mode which uses a clutch pack on the rear electric motor to allow for more controlled, low-speed crawling.
The adaptive hydraulic suspension allows the car to be lowered down or lifted up. In its highest mode there is a 890mm maximum wading depth.
Interestingly, compared to the smaller B5, the B8 feels more sorted off the beaten path. Its added heft helps round off bumps more easily, plus there’s added momentum behind it.
Lastly, in terms of noise, vibration and harshness (NVH), the B8 is a very quiet car to drive. As I mentioned above, the electric-first nature automatically makes this a quiet car.
Surprisingly, given the B8 is a huge 3.3-tonne box on wheels, there is very little road and wind noise. It seems Denza has put a big emphasis on sound insulation.
The Tank 500 has the maximum five-star ANCAP rating from testing in 2024. As standard, it has seven airbags and a comprehensive suite of driver-assist tech including AEB, lane departure warning, adaptive cruise control, tyre pressure monitoring, front and rear parking sensors and a 360-degree around-view camera.
The Denza B8 received a maximum five-star ANCAP safety rating based on testing conducted on the related B5 in 2025.
There are 14 airbags which notably includes coverage for the third row, plus autonomous emergency braking (AEB), blind-spot monitoring, front and rear cross-traffic alert, adaptive cruise control, front and rear parking sensors and a surround-view camera.
The majority of the active safety systems do a good job, remaining in the background and only activating when absolutely necessary. However, the driver attention monitor is over zealous and struggles to detect your eyes when you’re wearing sunglasses.
Thankfully, you can turn this off using the touchscreen but it needs to be done every single time you drive the car.
The Tank 500 is covered by a seven-year/unlimited km warranty, seven years' roadside assistance and seven years' capped price servicing.
The Tank 500’s 37.1kWh traction battery has an eight year/unlimited km warranty.
The first service is scheduled at 12 months/10,000km; the rest of the servicing appointments are set for every 12 months/15,000km. Lowest price per services is $335, highest is $975.
GWM has 122 dealerships nationwide at time of writing.
The Denza B8 is covered by a six-year, 150,000km warranty, whereas the battery pack is covered by an eight-year, 160,000km warranty. There’s also three years of roadside assistance.
This isn’t a standout warranty in the mainstream market, though compared to premium marques it’s a notable step up.
Logbook servicing is required every 12 months or 20,000km, whichever comes first.
The first five years' of servicing totals $3762, which averages out to just over $750 per service. This is just a tad more than the smaller B5, but it’s much cheaper than premium rivals.
