BYD Sealion 6 vs GWM Haval H6

What's the difference?

So, should Toyota, Tesla, Hyundai and others be worried about the arrival of the Sealion 6 and BYD’s new DMi powertrains? Yes, but not because it represents any major breakthrough in technology or dynamic prowess. 

Instead, the strength of the Sealion 6 is how average it is. It may not be the obvious class-leader in any particular area, but it does a good job in almost every measurable aspect and doesn’t possess any major flaws.

Yes, there are still questions about the long-term dependability of BYDs but that’s a risk any new owner will need to accept. But the very sharp pricing should tempt plenty of buyers to take that chance and continue BYD’s steady upwards trajectory in the Australian market.

The GWM Haval H6 has always been a value buy as a mid-size family SUV and although it previously wouldn’t have been at the top of my shopping list, this mid-life update has changed my mind.

It’s now more stylish inside and out, has more ergonomic storage and most importantly remains a cut-price offering.

Things aren’t perfect, as you still need to rely on the touchscreen for many key features and the suspension tune isn’t quite right.

This is one area where BYD has a mixed record. Not to be unkind or create an international incident, but the Chinese car industry has a history of not being totally original with all of its automotive designs.

However, things are improving and the Sealion 6 is a good example of the Chinese industry learning to develop its own style. While there are some subtle hints from European models, overall it’s a smart-looking mid-size SUV with some character to it - rather than being a bland imitation of something else.

One area where the Sealion is a cut above its competition is its size, being longer than and wider than the RAV4, Mitsubishi Outlander and Nissan X-Trail.

Although the GWM Haval H6 has only received a mid-life update, it’s rather comprehensive.

At the front there’s a new front fascia that features a grille that's eerily similar to the outgoing Hyundai Palisade.

There’s also a new LED daytime running light signature that features a plunging light strip. You can tell it’s a little tacked on to the headlight unit which remains unchanged, though it’s a nice point of difference.

Around the side GWM has made a big point of removing all the pre-update car’s chrome highlights, which is a great step in the right direction. In its place is a swathe of black finishes. It’s noticeable around the wheel arches and door sills, as well as around the windows and on the roof rails.

At the rear there are more obvious changes, including the removal of the full-width LED light bar. This is fantastic to see because they're being done to death by car brands at the moment.

In its place are two regular LED tail-light units which still look great and inoffensive.

Other changes at the rear include a revised tailgate design that’s now more angular and sharp, plus there’s now ‘GWM’ badging where ‘Haval’ once was.

Inside there are even more changes. In fact, it’s hard to see what has carried over with this update.

One of the most obvious changes is the inclusion of a new cream synthetic leather upholstery option. It’s not to my personal tastes, nor would it be something I’d recommend for someone using this as a family car.

However, it’s a no-cost option and provides a nice point of difference from the drab-looking black synthetic leather that’s standard.

Ahead of the driver is a leather-wrapped steering wheel which now has a thicker rim than before and now features sculpted indentations at the 10 and two o’clock marks.

It’s nice, but I do prefer how the old thinner steering wheel feels in the hand, plus the spokes where the buttons are placed are still too thick and highly placed.

It’s clear GWM is still sticking with the screen-heavy approach with this updated Haval H6. There’s still a 10.25-inch digital instrument cluster, but a larger 14.6-inch touchscreen multimedia system that sits proudly on the dash like an iPad.

The centre console has been heavily redesigned and it now looks similar to the Leapmotor C10.

The rotary gear selector has been moved to a column-mounted unit behind the steering wheel, freeing up more space.

Overall the Haval H6 continues to present well inside with a wide range of soft-touch materials on the dashboard. There is now also a rubberised section on the centre console which feels modern and fresh for a car that’s so affordable.

That external size translates to a roomy cabin, which also has some flair to the design but thankfully a bit more restrained than the smaller Atto 3 - which is a bit over-the-top in this reviewer’s opinion. 

The element that sticks out immediately is the large central touchscreen which, like other models in the range, can rotate either vertical or horizontal, depending on your preference.

I don’t understand the point of this, because when rotated vertically it impacts your forward vision and can interfere with the air conditioning vents; and I can’t even see it with my polarised sunglasses.

It simply makes more sense horizontally, but I guess all carmakers are looking for catchy gimmicks these days. But while it may seem like a cool party trick it remains somewhat confusing to me, like one more thing to go wrong. But maybe I’m just getting old and grumpy.

What I do like and think is a great idea is double smartphone charging pads in the centre console. And overall the design of the cabin feels well thought out and has plenty of useful storage areas.

The seats are fine, a little flat and the fixed headrests are irritating, but overall they’re soft and supportive enough.

The key in the second row seating is the amount of space, with the extra length of the Sealion 6 compared to its rivals showing up with more knee room in the back for families with growing teenagers or those who need to carry their adult friends.

There’s also a pair of USB ports in the back too, so everyone can keep their electronics charged.

The boot is a good size, measuring 425 litres on paper, and has a nice long and wide floor. But some of that space is thanks to the lack of a spare - so that counts against it in my book.

As standard both the front seats in the top-spec Haval H6 Ultra have electric adjustment. In particular, the driver’s seat has six ways of electric adjustment, plus adjustable lumbar support.

The driver’s seat itself is comfortable enough, though on longer drives I look for a little more thigh support. You’re unable to adjust either front seat to get more thigh support.

However, there’s both heating and ventilation as standard for both front seats. The steering wheel is also heated which has been a godsend in the cold Melbourne weather.

The buttons on the new thicker steering wheel now control different functions. There’s no longer a stalk dedicated to the cruise control, instead this is now done on the steering wheel itself.

Also on the right-hand side of the steering wheel there are still buttons that change the volume, but when you click just above the volume rocker it changes their function to altering what’s on the digital instrument cluster. I’m sure you’d get used to this if you owned this car, but initially it messes with your head.

Another thing is given the gear selector is now behind the steering wheel, the wiper controls are now on the indicator stalk. This now also means there’s no proper buttons or stalk to adjust the headlights.

Instead you need to either use the touchscreen or press the ‘auto’ button on the dashboard. Unless you frequently change your headlight settings, this likely won’t be an issue.

The 10.25-inch digital instrument cluster now has updated graphics and looks high-resolution. The interface is still dark, however, and you can only adjust the content on the right-hand side.

Moving across the larger touchscreen multimedia system looks fantastic and is a breeze to navigate thanks to the shortcut keys on the right and the handy swipe-down control centre menu.

There’s now wireless Apple CarPlay and Android Auto functionality in this car which is fantastic to see. It’s particularly good because if you want to use the wired version of either, the USB-A port to access this is still on the passenger side of the centre console.

However, while you’re using smartphone mirroring you can’t access the handy swipe-down control centre menu. You need to exit and go back to the native interface to use it, which completely undermines its existence.

Another gripe is there still aren’t many physical buttons around the H6's cabin, with only a few for select climate control functions. To change the temperature, for example, you either need to use the touchscreen or the voice assistant, which isn’t always intuitive.

Thanks to the relocation of the gear selector, storage in the centre console has improved massively. There are two cupholders, a wireless charger that now features ventilation to keep your phone cool, as well as another storage nook for your keys.

Other storage highlights up front include a large space under the centre console, a centre console box, a glovebox, as well as big door pockets with bottle holders.

Moving to the second row, this is where Chinese SUVs shine. At a leggy 182cm I have plenty of space behind my own driving position.

The rear bench is reclined a touch and plenty comfortable enough for longer trips. You could easily fit three adults in the back thanks to the minimal centre tunnel intrusion.

Second-row amenities include centre console-mounted air vents, a USB-A and USB-C port, as well as a fold-down armrest with cupholders.

At the back there’s now a hands-free power tailgate that’s standard across the line-up, except for the entry-level H6 Lux petrol trim. It’s very easy to use and particularly handy if you’ve got full hands.

The boot area in the Haval H6 is decent and there’s no load lip, making lugging items in and out a lot easier. GWM claims there’s 560L of boot space with the rear seats upright, which is great for the segment.

There are few boot-related amenities besides a single hook, 12V socket and a cargo blind.

Disappointingly there’s no spare wheel under the boot floor of the H6 Hybrid. Instead there’s only a tyre repair kit, which is surprisingly common among hybrids as the space where a spare wheel would typically go is taken up by the high-voltage battery pack.

The 2026 GWM Haval H6 range now only includes two trim levels – Lux and Ultra.

Pricing for carryover variants is down by up to $2000 over the pre-update model. The range now starts at $35,990 drive-away for the Lux petrol and extends to $50,990 drive-away for the new Ultra PHEV AWD.

It’s worth noting the variant we have on test here is the Haval H6 Ultra Hybrid which costs $43,990 drive-away. That’s incredibly affordable in this segment.

As standard all variants get 19-inch black alloy wheels, automatic LED headlights, LED tail-lights, heated and folding side mirrors, a hands-free power tailgate (exc. Lux petrol), 10.25-inch digital instrument cluster, 14.6-inch touchscreen multimedia system, wireless Apple CarPlay and Android Auto, voice assistant, 50W wireless phone charger, synthetic leather upholstery and electric driver’s seat adjustment.

It’s fantastic to see the multimedia system in the Haval H6 now supporting wireless smartphone mirroring, while also gaining a more powerful wireless charger that has ventilation.

Stepping up to the Ultra, as tested here, it gains rear privacy glass, a panoramic glass sunroof, head-up display, front stainless steel scuff plates, heated steering wheel, heated and ventilated front seats, as well as driver’s seat memory and lumbar support.

There’s a lot of nice kit in the Ultra that makes stepping up to it an easy choice. GWM even admits that’s what a lot of Australian buyers are doing, too.

While BYD has made its name in Australia as an all-electric brand it has always referred to itself as a 'new energy' company, and the Sealion 6 (and upcoming Shark ute) are why.

That’s because these feature BYD’s new 'Dual-Mode Intelligence' (DMi) powetrain - a hybrid system to you and me.

As mentioned above, the biggest difference between the Dynamic and Premium models is the powertrain, with two reasonably different systems.

The Dynamic is powered by a 78kW/135Nm 1.5-litre four-cylinder petrol engine, paired with a 145kW/300Nm electric motor - making for a combined system output of 160kW/300Nm. Notably, this powertrain only drives the front wheels.

In contrast, the Premium has an all-wheel drive set-up, combining a turbocharged version of the petrol engine (good for 96kW/220Nm) with a pair of electric motors, one on the front axle and one on the rear to produce a combined output of 238kW and 550Nm.

Both models get the same 18.3kWh ‘Blade’ battery, which is BYD’s proprietary technology underpinning all of its models and is attracting attention from other brands.

For reference, the Outlander PHEV has a 20kWh battery, Nissan’s X-Trail e-Power has a 2.1kWh battery, while the more conventional RAV4 Hybrid has just a 6.5Ah battery.

Unlike the petrol and the soon-to-be introduced PHEV variants, the GWM Haval H6 Hybrid’s powertrain remains unchanged with this update.

It’s still powered by a 1.5-litre turbocharged four-cylinder petrol engine that runs the Miller cycle, as well as a single electric motor that’s fed by a 1.8kWh lithium-ion battery pack. Total system outputs are a massive 179kW of power and 530Nm of torque.

This is mated to a Dedicated Hybrid Transmission (DHT) with drive sent to the front wheels only.

It’d be great to see an all-wheel-drive version of the Haval H6 Hybrid because it would be better able to harness the amount of power and torque better than the front-wheel-drive version can.

There are multiple modes to drive it in, including electric only, with the Dynamic able to go up to 92km on a single charge, while the Premium manages a claimed 81km.

However, it's important to note these are the NEDC standards and not the more real-world like WLTP,  so you may not achieve those in practice.

The claimed fuel consumption is an impressive 1.1L/100km for the Dynamic and 1.4L/100km for the Premium although again achieving those in the real world will take some effort.

With a 60-litre fuel tank BYD claims the Dynamic has a driving range of just over 1000km, while the Premium can manage around 960km.

It's also worth noting the Sealion 6 comes equipped with vehicle-to-load charging which means you can draw power from the batteries to run small electronic devices if you need to.

It’s a bonus feature that may or may not be of use, but is one of those things that may come in handy one day to get you through a camping trip or a BBQ at the park.

GWM claims the Haval H6 Hybrid consumes 5.2L/100km on the combined cycle (ADR 81/02).

During my testing I matched this figure, according to the trip computer, which is surprising as not many hybrid cars actually achieve their fuel consumption claims.

All Haval H6 variants, excluding the PHEVs, have a 61L fuel tank and require a minimum of 91 RON regular unleaded petrol.

GWM claims you can travel 1000km on a full tank of petrol in the Haval H6 Hybrid, but using my as-tested fuel consumption you can theoretically travel up to 1170km.

We drove the Sealion 6 Dynamic and despite having the less powerful powertrain it feels good on the road. The DMi system offers good performance, with quiet acceleration off the mark and a good integration between the petrol engine and electric motors. We haven’t driven the Premium yet, so we can’t make any comment on how different it feels.

It’s hard to make a definitive call on the Sealion PHEV powertrain because, like every plug-in hybrid, its greatest strength relies on how the owner operates it.

If you don’t charge the battery every day or so, you’ll just end up lugging around a battery and electric motor for little benefit. However, if you do keep the battery topped up, you can do most of your urban commuting without needing to turn the petrol engine on, which should result in some very low fuel consumption figures.

The company clearly knows this, which is why BYD Australia is offering a complimentary home charger to the first 3000 customers who order a Sealion 6.

Not only will that encourage sales but it will also help owners become evangelists for PHEVs in the future, because they’ll have the best possible experience.

So, a large part of its strength or weakness rests on the owner’s behaviour and that’s something we can’t assess.

As for the rest of the driving experience, the ride comfort is fine. It can’t match the class-leaders for compliance or dynamics, but the Sealion feels pleasant to drive around the urban environment and on the freeway at speed.

Biggest criticism is the steering is very, very light. While that makes parking easier, it feels so light you get very little feedback from the front wheels so it can feel vague at times.

Overall the driving experience is best described as fine. It doesn’t have any major vices but neither does it set any new benchmarks. 

Starting the GWM Haval H6, it’s generally quiet, but if the engine is bone cold it’ll fire it up to get the fluids warmed up.

Once the engine reaches an operating temperature it’ll typically switch off allowing you to drive around on electric power alone.

Depending on how much charge the battery has and also how cold the weather is, it can be surprising just how electric-heavy the H6 Hybrid can be. There were times where I accelerated all the way from standstill to 60km/h on pure electric power, then others where I was travelling along at 80-90km/h and the engine would shut off.

When you’re driving around in EV mode the car is super quiet. Under 20km/h though the car emits a noise that’s meant to alert pedestrians. You’re able to choose from two different noises and while neither bothered me, they did frustrate my passengers.

When the battery charge starts to deplete, or when you push the accelerator a little harder, the engine does naturally turn on. You can’t feel any drop off in terms of acceleration, though you can hear the engine turn on and start whirring away under the bonnet. Thankfully it’s nowhere near as loud and droney as a RAV4 Hybrid, for example.

With a massive 179kW and 530Nm, that’s a lot for a car that’s just front-wheel drive. In practice however, acceleration is rather linear, though if you do punt the accelerator the front wheels can get overwhelmed. It’s by no means a sports car.

There are three levels of regenerative braking available, including an additional one for one-pedal driving, which is quite rare for a hybrid car. For the majority of my driving I used the normal regen mode because it felt the most natural.

Unlike some hybrids, there’s no awkward interaction between the regenerative braking system and the traditional friction brakes. It can sometimes be a little jerky navigating in tight spots, but slowing down to a stop generally feels linear and normal.

There are also three settings you can choose for the steering feel. Although I sampled them all, the middle Comfort setting felt the most natural as the Light setting was too light and Sport was too firm.

Unlike some Chinese SUVs, the Haval H6’s steering feels like it has some connection to the wheels, though it’s not the most direct or fun to steer.

This feeds into the suspension. It’s clear the Haval H6 is still tuned for comfort because while it does iron out a lot of bumps, it gets overwhelmed easily with harsh or more continuous bumps. When this happens it can jostle and wallow around a bit, making it feel a bit like a boat.

Hopefully GWM is working on something for this because it did hire ex-Holden Lead Engineer of Vehicle Dynamics, Rob Trubiani, earlier this year as a Product Engineering Manager.

On the parking front, the Haval H6 comes with front and rear parking sensors, as well as a surround-view camera with fantastic quality. There’s also a handy semi-autonomous parking assist and a reversing assist.

Despite this, the Haval H6 is on the upper limit of what’s typically regarded as a medium SUV and it feels like it. This isn’t helped by its wide turning circle, meaning you’ll likely have to do some three-point turns in tight carparks.

Visibility has always been a sore spot for the Haval H6 and this remains the case with the update. Although you have an elevated seating position, the bonnet sits high, making you feel like you’re sitting in the car, rather than on it.

This continues with the rear visibility as the rear window is quite small.

It’s nice GWM has gone to the effort of reducing the amount of bings and bongs the safety systems make in this updated Haval H6. There’s one for the speed limit assist, though it only chimes once and not very loudly.

However, when you activate or deactivate adaptive cruise control the car talks to you with an artificial Australian woman’s voice telling you it's either on or off and to pay attention. This feels a little unnecessary.

The pre-update GWM Haval H6 petrol and hybrid received a five-star ANCAP safety rating back in 2021. It remains unclear whether this rating will carry over to the updated model.

As standard there are seven airbags, autonomous emergency braking (AEB), blind-spot monitoring, rear cross-traffic alert, traffic sign recognition, driver fatigue monitoring, a surround-view camera and rear parking sensors.

Stepping up to the Ultra gets you additional safety features like front parking sensors, semi-autonomous parking assist and reversing assist. It’s worth noting none of these features are offered on Ultra PHEV variants.

BYD is a small company but has partnered with mycar service centres to make maintaining your Sealion 6 easier. The Sealion is covered by BYD's six-year/150,000km warranty as well as its 10-year capped price servicing plan.

Service intervals are every 12 months/20,000km and prices range from $265 up to $1184 for the major eight year/160,000km tune up. Over the first five years, in keeping with most of its rivals, you’ll be paying $1648.

As I’ve written in previous BYD reviews, the biggest question mark hanging over the brand is arguably its long-term prospects. Quite simply, the brand is still too new to know how well it will perform on the used car market.

We also can’t tell you how it will hold up from a reliability point-of-view. We’re not suggesting there’s any doubt over its quality, but each car brand must prove itself reliable and dependable over time, and BYD hasn’t had that time yet.

The GWM Haval H6 continues to be covered by a seven-year, unlimited-kilometre warranty, while variants with a high-voltage battery pack have that covered under an eight-year, unlimited-kilometre warranty.

There’s also five years of complimentary roadside assistance and the first five services are capped priced.

Logbook servicing is required every 12 months or 15,000km, though the first service is required after 12 months or 10,000km.

During the five five years of ownership, servicing the updated Haval H6 Hybrid costs a total of $2145, which averages out to around $430 per service. That’s not bad but a Toyota RAV4 and a Honda CR-V are cheaper to service.
