GWM Haval H6GT vs Kia Stonic

What's the difference?

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.

All in all, the Stonic is a satisfactory daily driver, it’s just nowhere near ideal as a modern urban conveyance.

Sure, it’s reasonably priced in an increasingly expensive market, but it is very sluggish off the mark which is a solid negative against its overall rating. It also feels cheap inside and lacks contemporary driver-assist tech, such as adaptive cruise control.

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.

I spend the lion’s share of my time in large and upper large 4WDs, so spending quality time in something like this little hot hatchbac… er, small SUV, is a revelation and a lot of zippy fun. Like driving a go-kart without the fumes and the prangs.

The 2025 Kia Stonic Sport is 4140mm long (with a 2580mm wheelbase), 1760mm wide and 1520mm high. It has a listed kerb weight of 1227kg.

This is a slick-looking hatchbac… er, light SUV, and it looks suitably sporty. 

Though ground clearance is unlisted, it stands well clear of the road surface, giving this hatchbac… er, compact SUV, more presence than it otherwise might have.

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).

The Stonic Sport’s interior is a practical space but it feels a bit dated and underdone in a car market increasingly packed with well-equipped, cheaper and more contemporary SUVs.

The most obvious factors working against the Sport are its the 8.0-inch touchscreen multimedia (too small), the absence of wireless Apple CarPlay and Android Auto and wireless phone charging and multiple hard plastic surfaces.

Sure, the touchscreen is easy enough to operate, but it sometimes takes a few finger stabs to hit the sweet spot you’re after, and thankfully there are dials and buttons off-screen as alternatives for air con controls, etc.

There’s a satisfactory number of storage spaces in the front including two cupholders between the seats, a few little receptacles for your everyday carry gear, and bottle holders in each of the front doors.

The back seat is short on cupholders – there are none – but there are bottle holders in the doors, and the passengers back there get a USB-A port, a map pocket (in the back of the front passenger’s seat) and flip-down grab handles. There are no directional air vents.

Back-seat room is satisfactory for an adult without being spacious, but fine for kids. What do you expect in a small SUV?

In terms of packability, the cargo area (with the rear seat up and in use) yields a listed 352 litres of space. The rear seats are in a 60/40 split fold configuration and with them folded down there is a listed 1155 litres of useable room.

The rear cargo area has bag hooks, a storage space in the left-hand inner wall, and tie-down points at each corner of the floor.

A steel space-saver spare wheel is under the cargo area floor.

The Kia Stonic is available in three grades – the S ($25,460), our test vehicle, the mid-spec Sport ($28,590) and the GT-Line ($31,780), all prices excluding on-road costs. All have five seats.

Standard features include an 8.0-inch touchscreen multimedia system (with wired Apple CarPlay and Android Auto), satellite navigation, digital radio, two USB charging ports, single-zone climate control, six-way manual driver’s seat adjustment, a premium shift knob, premium steering wheel, and Tricot cloth trim seats.

It also has 17-inch alloy wheels, push-button start and rear privacy glass.

Standard paint is 'Clear White', but premium options including 'Sparkling Silver', 'Astro Grey', 'Aurora Black Pearl', 'Signal Red', 'Sporty Blue', 'Honeybee' and 'Snow White Pearl' cost $520.

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 2025 Kia Sonic Sport has a 1.0-litre three-cylinder turbo-petrol engine – producing 74kW at 4500-6000rpm and 172Nm at 1500-4000rpm – and that’s paired with a seven-speed dual-clutch automatic transmission. 

This pairing is a mostly punchy one, although definite lagginess is evident from a standing start often enough that it’s a disconcerting characteristic rather than a mildly annoying one.

This turbocharged engine used to only be offered in the top-spec GT-Line, so it’s a welcome addition to the other grades.

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.

Kia's official fuel consumption figure for the Stonic Sport is 5.4L/100km, on a combined (urban/extra-urban) cycle. And on this test I recorded 8.2L/100km.

The Stonic Sport has an 45-litre fuel tank so, going by my on-test fuel figure, you could reasonably expect a driving range of about 548km from a full tank. 

Fuel requirement is 91 RON 'standard' unleaded.

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. 

The Stonic Sport is a handy urban conveyance, but it is far from perfect.

It’s a small, light vehicle so it’s nimble for navigating through car-packed streets and convenient for tricky parking manoeuvres.

Steering is well weighted and precise.

And the turbocharged petrol engine is a welcome addition to the Stonic package, introducing a handy amount of power and torque which is sensibly harnessed and delivered – most of the time anyway – via the mostly clever transmission.

However, in stop-start, inner-city traffic or even a busy suburban area, the Stonic Sport struggles to get off the mark from a standstill, so much so that this one characteristic threatens to spoil the rest of the driving experience. 

Once the Sport is out on the open road, it’s a pleasant cruiser as this compact SUV simply rolls along.

Ride is firm – 17-inch wheels and low-profile tyres are the culprits here – and handling is impressive.

In terms of refinement the Stonic is mostly, um, fine but there is some tyre noise, especially over rougher roads out of the city, but it’s not terrible.

Every Stonic has three drive modes – 'Normal', 'Sport' and 'Eco' – each of which tweaks throttle response, engine output and transmission settings to best suit the driver and conditions. 

The Stonic is generally a reasonable daily driver, but the absence of adaptive cruise control is a let-down when it comes to highway running.

Not that you’ll be buying a Stonic with the aim of skull-dragging a 3500kg caravan along the highway, but it’s handy to know this Kia SUV’s towing capacities are 450kg (unbraked trailer) and 900kg (braked).

The Kia Stonic has the maximum five-star ANCAP safety rating as a result of testing in 2017, but that rating is set to expire in 2025.

Standard safety features include six airbags (dual front, front side and full-length curtain), as well as a suite of driver-assist tech, including AEB (with forward collision warning, car, pedestrian and cyclist detection), lane-keep assist, front and rear parking sensors and blind-spot collision avoidance. But it doesn’t have adaptive cruise control which is disappointing in this day and age.

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.

Kia’s seven-year/unlimited kilometre warranty applies to the Stonic and you have access to roadside assistance for up to eight years as long as you always get it serviced at an authorised Kia garage.

Servicing intervals are set at every 12 months or 10,000km, whichever comes soonest.

Service costs start at $290 (12 months/10,000km), peak at $727 (48 months/40,000km) and finish at $578 (84 months/70,000km) and the total over seven years is $3367; an average of $481 per workshop visit (correct at time of writing). That’s rather pricey for something in the small SUV market.
