What's the difference?
GWM has launched its first plug-in hybrid for Australia and in comes in the form of their mid-size SUV, the Haval H6 GT Ultra PHEV.
There's been a growing coolness towards EVs and their middle-ground counterparts of late but with a class-leading electric driving range of 180km, the new H6 GT Ultra may just warm you up.
GWM’s Tank 300 struck a chord with Australian buyers when it launched in 2023. The rugged, boxy design, serious off-roading ability and unbeatable value for money - especially compared with similar models like the Jeep Wrangler - won it a number of new fans.
But something was missing. With an uninspiring petrol engine and a patchy hybrid powertrain the only options, the Tank 300 was sorely missing a diesel.
GWM itself says about 75 per cent of models in the off-road-focused large and upper-large SUV segments are made up of diesel-powered SUVs, so it was missing out on a chunk of sales.
Thanks to some serious nudging from GWM Australia and New Zealand, the Chinese parent company saw the potential and have added a diesel engine to the mix. This is the same diesel unit found in the GWM Cannon and Cannon Alpha utes.
Is the diesel now the pick of the Tank 300 range? Or should you look at another oil-burning 4x4?
The new GWM Haval H6 GT Ultra PHEV has got to be one of the few plug-in hybrids that makes sense to me, given I live in a regional area. The longer electric driving range and DC charging capability offers far more convenience and practicality than the usual plug-in hybrids I’ve sampled.
It’s well-priced and has enough features for the average family. So, while I don’t love everything about it, it offers decent value for money.
The diesel is now the pick of the Tank 300 range. It’s the best fit for this vehicle and offers greater driver engagement than the petrol or hybrid.
It also has genuine off-road chops while still managing to suit family life.
While it could benefit from further refinements to on-road behaviour, cabin noise and the ADAS systems, none of these are deal breakers.
The fact that it is priced so keenly against some excellent competitors and is stacked with standard gear adds to the Tank 300’s appeal.
Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.
The H6 GT is the better-looking cousin to the regular H6 SUV because the swoopy rear end adds some much-needed personality.
It's the 19-inch alloys, Michelin tyres and red brake calipers that add to the sporty vibe.
It looks quite large for the segment and while I’m not a massive fan of the heavy plastic moulding around the base of the car, it’s got enough charm to appeal to a wide audience.
Head inside though and you're immediately hit by a strong plasticky presence, whether it be from actual plastics in the dash and door panels or the synthetic feeling of the upholstery itself.
The sunroof and red-stitched 'GT' on the seats add something but its all rather plain and lacks some personality inside.
I do like though that there’s no transmission tunnel, which means more legroom for middle seaters in the rear.
The only visible difference between the diesel and the petrol or hybrid 300s is a 2.4T badge. So you get the same boxy exterior as before.
It’s somewhat derivative and gives more than a nod to Jeep, but the design has intent - it looks capable off-road and for most people that’s enough. Luckily it is capable off-road. More on that later.
Inside the upright, shelf-like dash is appealing. I like that everything is nicely integrated, like the dual 12.3-inch screens which flow nicely into one another.
The big T-shaped three-spoke steering wheel looks cool and the aeronautical air vents are clearly inspired by Mercedes-Benz.
The chunky metal-look plastic glove box cover adds extra visual flair and the stitching throughout elevates the cabin further.
However, the futuristic looking gear shifter is chunky, takes up too much space and is unnecessary.
The most practical aspect of the H6 GT's cabin is its sheer size. It's a spacious cabin for the class and that translates to lots of passenger room in each row. Which is only let down by the relatively small boot capacity of 392L (when all five seats are in use).
The boot does feature a level loading space, a 12-volt power socket, retractable cargo cover and a powered tailgate. The latter I always appreciate with kids in tow.
There are lots of individual storage options with the front featuring a glove box large enough for an owner's manual, a middle console, two cupholders and two drink bottle holders. There's also a large shelf underneath the centre console, a dedicated phone cradle and a sunglasses holder.
In the rear there are two drink bottle holders, two map pockets and a couple of cupholders in a fold-down armrest. So plenty of choices for passengers.
Surprisingly, the most comfortable seats are in the rear which feature thick padding, good lumbar support and long seat beds. The electric front seats have heat and ventilation functions, as well as adjustable lumbar support but the lumbar sits too low and the seat backs curve in too far for them to be called comfortable on a longer journey.
The tech is made up of a 12.3-inch touchscreen multimedia system and 10.25-inch digital instrument panel and while they look nice, they're basic at best. The multimedia system is simply laid out but lacks any real customisation and doesn't have sat nav.
The touchscreen can be laggy and there is wired Apple CarPlay and Android Auto. GWM has confirmed that wireless phone mirroring is due sometime later this year.
Charging options include four USB-A ports (but no USB-C ports), two 12-volt sockets and a wireless charging pad but the pad didn't always work for my iPhone 15 Pro Max (whether that is a user or software issue, I'm not sure).
Up front the Tank 300 offers a commanding view of the road and it’s easy to find your perfect driving position thanks to the power-adjustable seats.
Those seats have good side bolstering but could do with a little extra cushioning for the thighs. The Nappa leather-appointed seats in the Ultra look and feel lovely.
Storage is average for the segment with room for larger bottles and additional flat items in the door pockets, and a well-sized central bin that also houses two cupholders, although they sit low in the cavity and two coffees sit awkwardly together.
The Tank has one USB-C port for charging only but another USB-A port up front for connectivity. You shouldn’t need that given Apple CarPlay and Android Auto is wireless.
Keen off-roaders will have fun with the extensive Tank Expert Mode in the multimedia screen, which allows you to individualise your 4WD experience.
Beyond that the screen is neatly laid out, responsive and easy to use. GWM has come a long way when it comes to in-car tech. The icons on the digital instrument cluster, however, are still too small.
There’s ample leg room in the rear, with space between my knees (I am 184cm tall) and the rear of the front seat, and enough toe room. It doesn’t feel enormously spacious across the rear row but three kids should be comfy. Headroom is enhanced by a scalloped section of the roof specifically for rear-seat passengers, but it doesn’t leave a huge amount of space for taller people.
The rear seat bench is flat but the backrests have some support and overall the seats back there are comfortable.
You’ll find lower rear-seat air vents, map pockets, a fold-down central arm rest with two cupholders, room for small bottles in the doors and two USB-A ports.
The boot can take 400 litres with all seats up and 1635L with the rear seats folded. That figure is measured from the floor to the top of the rear seats.
Jeep says the Wrangler has 898L capacity with all seats in place but that is measured from the floor to the roofline.
There is no under-floor storage in the 300’s boot and the full-size spare wheel is housed in traditional 4x4 fashion on the tailgate.
There is only one grade available for the H6 GT, which is the Ultra and it's available with two powertrains - a 2.0L turbo-petrol engine or the 1.5L turbo-petrol plug-in hybrid powertrain of our test vehicle.
Its sharp drive-away pricing of $53,990 makes it very competitive against its rivals. The BYD Sealion 6 Premium sits at $52,990 MSRP and you have to jump into the Mitsubishi Outlander PHEV Exceed ($69,290 DA) if you want to match on some of the standard equipment of the H6 GT Ultra.
While the PHEV offers a class-leading electric driving range of up to 180km, it features pretty much the same equipment as it's non-hybrid sibling but is $9000 more expensive.
The premium features include a panoramic sunroof, synthetic leather and suede upholstery, electric front seats with heat and ventilation functions, a heated steering wheel, a powered tailgate, powered and heated side mirrors and rear tinted glass.
Technology includes a keyless entry/start, 10.25-inch digital instrument cluster, dual-zone climate control, 12.3-inch touchscreen multimedia system, coloured head-up display, four USB-A ports, two 12-volt sockets, a wireless charging pad, FM/AM radio, Bluetooth, and wired Apple CarPlay and Android Auto.
However, it doesn't have a spare tyre (just a repair kit) or sat nav and there's no wireless phone mirroring. At least, not yet but GWM has confirmed that they are working on getting the phone functionality up and running sometime later this year.
One of the key selling points across GWM’s entire range is value for money, and the Tank 300 has always had that in spades.
As with the petrol and hybrid 300, the diesel is offered in two well-specified model grades - Lux and Ultra.
At $47,990 drive-away, the Lux diesel is $2000 more than the Lux petrol, but $3000 cheaper than the Lux hybrid.
The Ultra diesel, at $51,990, is $1000 pricier than the petrol equivalent and $5000 more affordable than the hybrid Ultra.
The GWM Tank 300 diesel Lux is also more affordable than equivalent grades of a number of ladder-frame 4x4 SUV rivals like the Isuzu MU-X, Toyota Fortuner, SsangYong Rexton and the Ford Everest.
It’s also significantly more affordable than the Jeep Wrangler, with the Tank 300 Lux costing about $30,000 less than a Wrangler Unlimited Sport S.
Note however that many of those models - except the Wrangler - have the option of seven seats, whereas the Tank is strictly a five-seat proposition. If you want a third row, check out GWM’s Tank 500.
There are cheaper off-road large SUVs out there – the LDV D90 and Mahindra Scorpio. But the Tank 300 is a more refined and higher-quality offering than those models.
Standard gear in the Lux includes 17-inch alloy wheels, synthetic leather seats and steering wheel, power-adjustable front seats, dual-zone climate control, seven-colour ambient lighting, keyless entry and start, a sunroof, power-folding mirrors, paddle-shifters, a nine-speaker audio system with digital radio, built-in sat-nav, and a pair of 12.3 inch digital displays with wireless Apple CarPlay and Android Auto.
It also gets roof rails, side steps, privacy glass, all-terrain mode selection and a rear diff lock.
The Ultra upgrades to 18-inch wheels, Nappa leather-accented seats, heated and ventilated front seats, a heated steering wheel, more adjustment for the front seats and a memory setting, a massage function for the driver’s seat, a wireless phone charger, 64 colours in the ambient lighting suite, and a nine-speaker premium audio system.
There is nothing obvious missing from the standard features list, but I don’t know why a wireless device charger is limited to the top grade.
The new H6 GT Ultra has a plug-in hybrid powertrain that combines a 1.5-litre four-cylinder turbo-petrol engine with three electric motors, two at the front and one at the rear.
Together they produce a combined power output of 321kW and 762Nm of torque. That gives this 4WD a 0-100km/h sprint time of 4.9 seconds. So it's a quick SUV but somehow it doesn't manage to feel 'blow-your-hair-back' quick.
The engine is paired with a two-speed dedicated hybrid transmission (DHT) and the switch between the electric and engine components is practically seamless.
The big news with the Tank 300 is, of course, the new engine.
It is a 2.4-litre four-cylinder turbocharged diesel engine borrowed from the GWM Cannon and Cannon Alpha utes.
It pumps out 135kW of power and 480Nm of torque. That’s more torque than an MU-X but not as much as an Everest.
It is paired with a nine-speed automatic transmission and has part-time four-wheel drive.
If you need to tow, the diesel has a 3000kg towing capacity, which is 500kg more than the hybrid and petrol. It can’t beat the 3.5-tonne towing capacity of the MU-X and the Everest.
Payload has also increased compared with the petrol and hybrid, up from 400kg to 600kg.
GWM says it conducted extensive testing internationally but also in Australia to improve towing performance. There are approximately 20 different parts compared with the other powertrain variants to get the best out of towing in the diesel.
A rear diff lock is standard on both grades while the Ultra gains a front diff lock.
The new H6 GT has a ternary lithium battery with a large 35.43kWh capacity. It also has a Type 2 CCS charging port, which is pretty rare but welcome on a plug-in. This system can accept up to 6.6kW on an AC charger and up to 48kW on a fast DC charger, which is great.
It means you can plug in at a DC fast charger during a road trip like a normal EV and that improves overall efficiency.
The combined fuel cycle figure is just 0.8L/100km and with the 55L fuel tank, you’ll get a theoretical driving range of over 1000km. That’s just something to consider right there. The considerable pure electric driving range of up to 180km also ensures that you can do your daily errands and school run without really touching the fuel tank.
Which I totally proved this week after doing 469km of open-road driving and my daily 'urban' errands and only using 2.3L of fuel all week. I had two full charges during my week and that means my real-world usage beats the claimed figure at 0.49L/100km. Haval H6 GT for the win.
The diesel Tank 300 consumes 7.8 litres of fuel per 100 kilometres on the official combined cycle, which is better than the 9.5L figure for the petrol and the 8.4L quoted for the hybrid.
That figure also sits somewhere between a 2.0-litre bi-turbo Everest (7.1L/100km) and a 3.0L MU-X (8.3L/100km).
It has a 75-litre fuel tank and GWM claims an NEDC range of about 950 kilometres. GWM says the Euro 5 engine does not require Adblue.
Given the restrictions of a media launch, we did not obtain real-world fuel use figures.
The new powertrain took a few days to get used to because it doesn't behave like some of the PHEVs I've driven before. The emphasis is on EV driving rather than the ICE components. The pedals are quite stiff which takes a moment to adjust to, but the auto-hold braking and strong regenerative braking means it's difficult 'creep' forward like you can in a regular ICE car.
The one-pedal function is true one-pedal driving and if you time your deceleration right, you won't touch the brake pedal. You'll either like that or you won't but it's been nice to use this week.
The power delivery is prompt and there's a lot of power available. It doesn’t feel wicked quick like a performance EV but it certainly has enough punch to satisfy. You don’t notice when it switches between the engine or motor, which makes it a very smooth powertrain.
The steering is a little spongy but responsive enough to feel spry for quick lane changes. It's just not particularly dynamic on a winding road with the combination of the firmer suspension and soft steering.
Road noise can creep up at higher speeds and there is an annoying whirring sound from the motors that my son likened to a dull aeroplane engine roar.
The suspension is on the firmer side and you notice the bumps but you also don’t wince when you hit one. Visibility is okay but the thick A-pillar can get in the way when you're scanning the road at intersections, and the back window is narrow. A digital rear-view mirror would be a handy feature for the model.
The H6 GT Ultra PHEV is pretty easy to park because it has a clear 360-degree view camera system and parking sensors at the front and rear. The 12-metre turning circle makes it pretty friendly in a carpark, too.
I last drove a Tank 300 in late 2023 and it was the hybrid variant. While the hybrid has some positives, its driving characteristics were not high on that list.
It had an erratic throttle response, hesitation on take-off and it felt underdone.
In contrast, this new diesel variant just feels like the right fit for this SUV.
There is slight lag accelerating from a standing start, but the powertrain is torquey and there’s plenty on tap when overtaking or just increasing speed when already on the go. GWM has not provided a 0-100km/h time.
It is clear you’re in a diesel as soon as you turn on the ignition - it has that typical diesel rattle, but it is not as unsophisticated as some oil-burners I have driven.
The cabin could do with some extra insulation with wind and tyre noise detected, but it’s hardly a deal breaker.
Given the vehicle’s size, heft (nearly 2.3-tonne kerb weight) and the fact it’s shaped like a brick, the 300 holds its nerve on winding stretches of road with only a little body roll. In saying that, best not to treat it like a Mini Cooper on your favourite twisty road.
Ride quality is a bit mixed. We only drove the Ultra on 18-inch wheels and while it manages to soak up bumps, the ride is jittery, and that’s even more evident on uneven road surfaces.
Steering is heavily weighted and a little vague, but fine for a big off-roader, and the brakes need to be pushed hard.
One quirk is the indicator - it appears to be a one-touch setup for indicating to change lanes, but then the indicator stays on. I tried several times to test this, even flicking it to the opposite side to turn it off and it was very stubborn.
The good news is it appears GWM has toned down the awful indicator sound of its earlier models and is now much more subtle.
So on-road the Tank 300 is more than competent, and a much nicer vehicle to drive in an urban setting than a Jeep Wrangler, for example.
We also drove it briefly on an off-road trail, and in low range the Tank 300 proved that it can do what it says on the box.
I’m no off-roading expert and there are much more challenging trails out there, but I had confidence that the Tank 300 would not let me down traversing the many chunky rocks, massive holes and fallen tree limbs.
The Haval H6 GT has a maximum five-star ANCAP safety rating from testing done in 2022 and scored 90 per cent for adult protection, 88 per cent for child protection, 73 per cent for vulnerable road users and 81 per cent for safety assist.
It features seven airbags, including a front centre airbag.
There are seatbelt reminders (all seats), hill-start assist, tyre pressure monitoring, front and rear parking sensors, surround-view camera system, adaptive cruise control with stop and go, rear cross-traffic alert, lane keeping aid, lane departure alert, rear collision warning, forward collision warning, traffic sign recognition and a driver monitoring system.
The autonomous emergency braking (AEB) with cyclist, pedestrian, car and junction turning assist is operational from 5.0 - 85km/h (up to 150km/h for car detection).
There are two ISOFIX child seat mounts and three top tether anchor points and the rear seat is wide enough to accommodate three child seats side by side.
The driver assist features seem to work smoothly most of the time but I did find the driver attention monitor a bit annoying, as you get a few more chimes than you need and the lane keeping aid feels too jerky.
ANCAP awarded the Tank 300 a five-star crash safety rating from testing done in 2022, scoring highly across all four of the major test categories.
GWM says it is waiting to hear from ANCAP but expects the diesel to be covered by the same rating.
As well as seven airbags including a front centre bag, the Tank 300 has a long list of safety gear covering both the Lux and Ultra.
There’s a suite of collision mitigation systems that includes auto emergency braking (AEB), lane departure warning, lane-keep assist, emergency lane keep, lane centring, front and rear collision warning, front and rear cross-traffic alert and lane change assist.
It also has driver fatigue monitoring, a rear seat child monitor, door opening warning, adaptive cruise, traffic sign recognition and hill-descent control.
I noted this in my recent GWM Haval H6 GT PHEV review, but GWM has made consistent tweaks to improve its advanced driver-assist systems (ADAS) and as a result they are less intrusive than they were when the Tank 300 launched in 2023.
There is still the occasional tugging of the wheel but it’s much less of a tug-of-war than it once was.
For the first 45 minutes of our test drive there was an annoying beep every 10 seconds that my co-driver and I could not identify. There was no icon on the driver display to indicate that it was a lane departure warning or speed limit alert, but eventually it just stopped. We still have no idea what it was but it was, thankfully, not present in the vehicle we drove in the second half of the launch drive.
GWM offers the H6 GT with a seven-year unlimited kilometre warranty, which is becoming the normal term for the class and you will enjoy five years of roadside assistance through Allianz.
There is also a five-year capped-price servicing program that costs $1680, which is competitive. The first service is at 10,000km but subsequent intervals are spaced at every 12 months or 15,000km.
GWM covers the Tank 300 with its seven-year/unlimited-kilometre new-vehicle warranty, which is an impressive offer.
You are covered for seven years of roadside assist and the Tank is offered with a seven-year capped-price servicing program.
GWM is yet to confirm the Tank 300 diesel’s servicing offer (including pricing), but expect a service schedule similar to the Cannon ute with the same powertrain.
That means the first service might be required at 5000km or six months and beyond that it will need a service every 12 months or 10,000km, whichever occurs first.
