BYD Sealion 6 vs GWM Haval H6GT

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.

New-car buyers wanting a medium-size SUV under $65K are faced with a bewildering choice of makes and models but the H6GT PHEV Hi4 is worthy of consideration.

Its value-for-money drive-away pricing combines a spacious and classy cabin, sporty all-wheel drive persona and rare petrol bowser visits if overnight charging and daily EV-only driving are fully utilised.

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 premium GWM Haval H6GT PHEV range shares much of its underpinnings and cabin design with the regular H6 line-up, the GT has a unique and distinctly sporty persona with its coupe-style roofline and more engaging suspension tuning and steering feel.

The interior blends soft-touch surfaces, synthetic suede and exposed stitching with satin chrome and faux carbon fibre highlights resulting in a sumptuous cabin design with strong visual and tactile appeal.

In terms of wheelbase (2738mm) and overall length (4727mm) the H6GT is among the physically largest of competitors in the medium-size SUV segment, which contributes to the cabin’s roomy ambience that defies expectations that a coupe compromises interior comfort.

This effect is enhanced by the panoramic sunroof and column-mounted gear selector that frees up space on the centre console for additional storage and functionality.

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.

Our test vehicle’s 2045kg kerb weight and 2495kg GVM (how much weight it can legally carry) allows for up to 450kg which could easily be consumed by four large adults and some light luggage.

It’s also rated to tow up to 1500kg of braked trailer which would be handy for those with recreational activities in mind like towing a light camper or bike trailer, but GWM does not publish how much weight our test vehicle can legally carry and tow at the same time.

It also offers up to 3.3kW of V2L (vehicle to load) capability using a charging port adapter to provide electricity for numerous domestic appliances, from laptops and power tools to camping equipment.

There’s ample space for the driver and front passenger along with storage including a bottle holder and bin in each door, a single glovebox and an overhead glasses holder. There’s also a two-tiered centre console with the top level providing open storage, wireless phone charging, two cupholders and a lidded box while the floor level adds more open storage plus a 12V socket and USB port.

Rear seat passengers also enjoy generous space, including tall people given I’m 186cm and when sitting behind the driver’s seat set in my position I still have 80mm of knee clearance and 80mm of head clearance. It’s a similar story in the centre seat, enhanced by a virtually flat floor with no transmission hump to straddle.

There’s also a storage bin in each rear door plus pockets on both front seat backrests. The centre seat backrest folds forward to serve as an armrest for two complete with cupholders, while the rear of the centre console provides adjustable air vents and two USB ports.

The rear luggage area offers side bins, another 12V socket and up to 392 litres of load volume with the 60:40-split rear seat backrests upright, which is ample for a weekly grocery shop. This increases to 1390 litres (almost 1.4 cubic metres) with the seats folded flat to create an extended load area.

Our test vehicle is available in one hybrid drivetrain specification comprising a turbocharged 1.5-litre four-cylinder petrol engine, four-speed DHT (Dedicated Hybrid Transmission), two electric motors and a plug-in propulsion battery for $54,990 driveaway.

This pricing looks enticing compared to the list prices (before on-road costs) of plug-in rivals like the BYD Sealion 6 PHEV Premium AWD ($52,990) or Mitsubishi Outlander PHEV Exceed Tourer AWD ($58,740). Our example is finished in Atlantis Blue which is one of several premium metallic paint options that adds $495 to the price.

The H6GT PHEV Hi4 comes standard with generous luxury features including:

• 19-inch black alloy wheels with Michelin 235/55R19 tyres and a repair/inflator kit (no spare)
• full LED lighting including daytime running lights (DRLs)
• electric tailgate with integrated spoiler/sunshade and hands-free opening
• roof rails
• panoramic sunroof
• cosmetic dual exhaust outlets
• contrasting red brake calipers

Inside the keyless-entry cabin is:

• push-button start
• heated/ventilated front seats with synthetic suede-accented trim and 8-way power adjustment for the driver (4-way for the passenger)
• dual-zone climate control
• rear privacy glass
• heated door mirrors
• heated multi-function steering wheel with synthetic leather trim
• head-up display
• surround-view camera
• wireless phone charging
• two 12V sockets
• four USB ports

The driver is also treated to a 10.25-inch digital instrument cluster which shares dash space with a large 14.6-inch multimedia touchscreen. The latter serves as central command for the GT’s nine-speaker premium audio system featuring GWM’s latest Coffee OS software with ‘Hello GWM’ voice command, DAB digital radio and smartphone connectivity for Apple and Android devices.

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.

The plug-in hybrid drivetrain in the H6GT comprises a 1.5-litre turbocharged four-cylinder petrol engine which produces 110kW of power between 5500-6000rpm and 240Nm of torque across a broad rev band from 1800-4000rpm. It drives the front wheels and serves as a generator as required to maintain battery charge.

This is paired with individual electric motors on the front and rear axles, with the front motor producing 80kW and driving the front wheels while the rear motor produces 135kW and drives the rear wheels, resulting in all-wheel drive on demand. 

The combined output is rated at 321kW and 642Nm.

The automatic four-speed DHT (dedicated hybrid transmission) intelligently combines outputs from the petrol engine and electric motors to continuously optimise efficiency and performance between them, in any of the three driver-selectable power mode settings comprising EV (battery only), EV Priority (minimal engine input) and HEV (full hybrid).

The DHT also offers a selection of drive modes including ‘Normal’, ‘Sport' and ‘Eco’ plus numerous 4WD settings tailored to enhance performance on snow, sand, mud and when towing.

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. 

The H6GT PHEV offers a comfortable and spacious position thanks to its combination of a flat-bottom steering wheel providing easy access and plenty of torso room, along with powered seat adjustment and a big left footrest. However, some rake adjustment in the base cushion would be welcome for better thigh support on longer drives.

Ride and handling benefit from GWM’s local chassis tuning input. The steering is nicely weighted and responsive, albeit best appreciated with the active lane-keeping function switched off given its tendency to harshly tug the wheel when making its steering corrections.

The hybrid drivetrain has vigorous response thanks to more than 600Nm of near-instant torque providing enough shove to accelerate rapidly from a standing start to triple-digit speeds in less than five seconds. We found the ‘Sport’ drive mode the most engaging and enjoyable but the ‘Normal’ and ‘Eco’ modes are fine for daily commuting.

Our other gripes from a driver’s point of view are that the base of the rear window is positioned quite high in the tailgate, resulting in the solid tailgate area below it restricting vision of vehicles travelling close behind when viewed through the central mirror.

We also found that the pedestrian warning sound, which automatically starts at speeds under 30km/h, is too loud inside the car and becomes annoying when crawling along in heavy traffic, negotiating tight inner-city streets or parking.

Both Sealion 6 variants come equipped with autonomous emergency braking, front and rear cross-traffic alert/braking, 'Forward Collision Warning', 'Rear Collision Warning', lane departure warning/prevention, blind-spot detection, traffic-sign recognition, door-opening warning, trailer stability control, auto high beam, a 360-degree monitor, adaptive cruise control as well as front and rear parking sensors. Plus, it can even detect if you’ve left a child or pet inside the car.

ANCAP had not crash-tested the Sealion 6 at the time of publication, but with its comprehensive list of safety items it should tick most of the boxes when it comes to protecting its occupants and pedestrians.

The GWM Haval H6GT PHEV was awarded a maximum five-star ANCAP rating under 2022 protocols, and has seven airbags for protection in case of a collision.

It also comes standard with:

• autonomous emergency braking (AEB) with pedestrian, cyclist and crossroads detection
• lane-keeping
• rear cross-traffic alert with autonomous braking
• front/rear parking sensors
• Surround-view parking cameras
• tyre pressure monitoring
• traffic sign recognition
• adaptive cruise control

On top of these features, the rear seat has two ISOFIX child seat anchorages and three top-tethers.

The H6GT PHEV comes standard with GWM’s seven year/unlimited km warranty plus a separate eight year/unlimited km propulsion battery warranty and five years of roadside assist.

Scheduled servicing is every 12 months/15,000km whichever occurs first. Capped pricing applies to the first five scheduled services up to five years/70,000km totalling $2030 or an average of $406 per service. 

This warranty/service package is among the strongest available in its vehicle segment.
