MG ZS vs BYD Sealion 6

What's the difference?

The MG ZS Essence with the 1.5-litre petrol engine has many strengths - price and value for money, practicality and space, good looks… and the only area where it really struggles to match its rivals is its underpowered engine. 

The good news is the Essence also comes with a turbo engine and while this isn’t a race car by any means, turbocharging is a way to add the oomph needed in a car this size. 

Stepping up to the MG ZS Essence Turbo costs an extra $2000, but if you can make the budget stretch you’ll have the complete package of value, looks, practicality, safety and much better performance for more enjoyable driving.

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 ZS's good looks is another strength.

The new-gen ZS arrived in Australia late in 2024 and this petrol version landed in February 2025. The styling looks more expensive and premium than its price tag would suggest. The sleek nose, the refined tail-lights, a pleasing profile all make for a good looking small SUV.

There are many interesting elements in the design - the grille and its aggressively looking flanking 'air intakes', the crease through the door panels, the little fin that meets the tail-light.

Squint and it looks like a mini Ford Territory. Sort of…

The cabin of the ZS Essence is equally refined with a modern design and soft touchpoints throughout. It’s a minimalist and spacious place free from button clutter.

The ZS is 4430mm long, 1818mm wide and 1635mm high. Ground clearance is 161mm, in case you’ve been lying in bed wondering.

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.

Practicality is a big strength, too, with a proximity key that’ll unlock the car when you touch the door handle, and a cabin with good legroom and headroom even for me at 189cm tall.

There's also a wonderfully simple charging pad for your phone - it's a large area on the centre console which works well in terms of connection but also in terms of wasy access. Many rivals will hide phone chargers away is small crevices that make them hard to extract or even pop in.

You'll find four USB ports, too plus a 12V charger, too.

Clever storage like a shelf built into the dash for loose objects, four cupholders and big door pockets are also on hand.

The boot is also a decent size for a small SUV at 443 litres which is bigger than many rivals, including the Subaru Crosstrek.

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.

Price is key to BYD’s success in Australia. Quite simply, the Chinese brand has undercut its rivals and consumers have responded to that, unsurprisingly in these tough economic times. The Sealion 6 follows the same path blazed by the Atto 3, Dolphin and Seal, offering plenty of vehicle for your money.

BYD Australia has kept it really simple, offering just two models - Dynamic and Premium - with very similar specification and separated primarily by powertrains.

The Dynamic is a less powerful, two-wheel drive option, while the Premium gets more grunt and all-wheel drive; but we’ll detail that later.

Both the Dynamic and Premium come with 19-inch alloy wheels, power-operated tailgate, a panoramic sunroof, powered front seats that are heated and cooled, a 15.6-inch touchscreen, Infinity premium audio, two wireless phone chargers and wireless Apple CarPlay and Android Auto.

The only non-powertrain difference between Dynamic and Premium is a head-up display on the latter model.

One noticeable absence from the Sealion though is a spare tyre. There’s not even a space-saver, just a tyre repair kit, which is disappointing and out of touch with the unique demands of the Australian market.

The Dynamic is priced from $48,990 (all prices exclude on-road costs), while the Premium starts at $51,990.

To put that into context with its competition, the Toyota RAV4 Hybrid range begins at $42,250 for the GX and stretches to $51,410 for the range-topping $51,410.

While, if you’re looking at an electric alternative, the Tesla Model Y currently starts at $55,900. The most direct rival, however, is the Mitsubishi Outlander PHEV which is only available with all-wheel drive and stretches from $57,290 to $73,790 across five variants.

Okay, we've listed a lot of strengths for the MG ZS but the engine isn’t one of them. The 1.5-litre four-cylinder petrol engine makes 81kW and 140Nm.

Really, power needs to be at least 100kW and torque closer to 200Nm in something weighing 1330kg otherwise acceleration is going to feel woeful - which it is.

Seriously, the first time I tried to overtake I looked down to see if the handbrake was still on.

Not helping performance is a CVT (Continuously Variable Transmission) which, while good for fuel economy, seems to have trouble getting power to the road effectively.

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.

Official fuel consumption for the combined (urban/extra-urban) cycle is 6.7L/100km, which isn’t outstanding, especially compared to the hybrid version which can get 4.7L/100km.

Our own testing after city driving and motorways saw 7.9L/100km. Not the most efficient engine in the range, so if it’s saving petrol you want then go for the hybrid, or better still, the electric version of the ZS.

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.

The lack of oomph from the 1.5-litre naturally aspirated four-cylinder engine affects the driving experience of the ZS. This lack of accleration is hampered not just by the low outputs of the engine but also by the transmission, which is a CVT and these don't favour getting power to the road as effectively as torque convertor transmissions.

Handling is good for this class, with the ZS feeling stable under most conditions. Steering is excellent, with a nice weight and accuracy to it.

And while the ZS is no prestige car, the ride is comfortable, composed and better than many small SUVs at this price point.

Other pluses include its smaller size which makes it easy to manoeuvre in city traffic and park in tight spaces.

The final driving score however is dragged down by the engine and transmission which fail to provide the acceleration needed to easily overtake, merge or move quickly when needed at stop signs or out of car spaces on busy roads.

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. 

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.

Ownership costs are a strength, too. The MG ZS is covered by a 10-year/250,000km warranty.

MG’s ‘Precise Price’ service plan locks in the cost of servicing with 12-month/15,000km intervals and a cost of about $1200 over five years.

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.
