BYD Sealion 6 vs MG HS +EV

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 MG HS +EV Essence is a nicely specified medium SUV that should suit a lot of people. It looks really nice and I love that it's fairly practical with its features and size but would like some of the tech to improve. It’s not always seamless to use and in this market, tech is very important. The price tag and the on-going costs are hard to beat and if you’re looking for a greener option that will happily cruise in the city or on the open-road, this isn’t a bad option.

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.

It has an inoffensive exterior design that you won’t be embarrassed to be seen in. Curvy in all of the right places, it still manages to look sharp with its tapered LEDs and chrome accents.

It sits firmly within the medium SUV specs at 4574mm long, 1876mm wide and 1685mm high, so navigating your local shopping centre car park will be manageable.

The interior looks polished with the Bader leather sports seats and their suede-like inserts. The air vents are cute and add some personality to the robust dashboard.

There’s a plethora of soft touchpoints throughout that enhance the overall comfort and refinement, too.

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.

The cabin space is very practical with its size. Each row has a decent amount of head and legroom. The big sunroof also makes the cabin feel airy and light-filled, which adds to that roomy feeling.

The leather-accented sports seats are quite comfortable and both are electric but the passenger side misses out on additional lumbar support.

I did have a few comments this week about the front seats, though, mainly that it feels like you’re perched forward in them. It would have been nice to be able to dip the bottom of the seats back.

The individual storage options are solid for this sized SUV with a glove box, two cupholders, drink bottle holders in the doors for front occupants and an air-cooled middle console box.

I missed having a utility tray next to the two USB-A ports and 12-volt outlet, as the Essence features wired Apple CarPlay and Android Auto, but there is a dedicated phone holder next to the cupholders.

Back seat passengers enjoy two cupholders in the fold-down armrest, map pockets and drink bottle holders in the doors.

The seats in the back are well padded but you feel like your knees are propped up a bit because of the shallow footwell. Taller passengers may feel like they’re folding in on themselves.

The technology looks good but isn’t always easy to use. The 10.1-inch touchscreen multimedia system is simple to understand but regularly feels laggy.

It has built-in satellite navigation but a lot of the controls are found via accessing the touchscreen – like the climate control and heating function for the front seats.

The 12.3-inch digital instrument panel is very easy to read but not really customisable.

Charging options are okay and I like the two USB-A ports in both rows but there’s no wireless charging pad or USB-C port which would provide faster charging speed.

The boot is a decent size for the class at 451L and you can bump that up to 1275L if you fold the back seats down. The rear seats have a 60/40 split for added practicality.

There’s a cargo blind and some underfloor storage for the charger and a tyre puncture repair kit. I liked using the powered tailgate but found it a bit glitchy, it sometimes stopping mid-action.

There are only two models in the HS +EV line-up and the Essence is the top dog.

It will cost you $51,990 drive-away and that positions it as one of the most affordable options relative to its rivals. Only the Haval H6 is more affordable at $41,990 (drive-away) but admittedly, it’s by a fair chunk of change - almost $10K!

The Essence is well-specified with Bader leather-accented trims, heated front seats, electric front seats with four-way adjustment for the passenger seats and six-way for the driver, a powered tailgate, as well as a massive panoramic sunroof. The middle console is even cooled with air-control for added convenience.

The exterior hosts full LEDs with its daytime running lights, headlights and tail-lights, as well as, a heated rear window with timed cut off.

It also sports dual-zone climate control up front and directional air vents in both rows, plus multiple charging options add to interior practicality.

Its technology feels up to category standard with the sizing but the usability isn’t as great as its rivals. More on that later. 

And an added bonus. All the paintwork colours are included in the price.

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.

Both HS +EV models share a 1.5-litre, four-cylinder petrol engine and electric motor hybrid combination. Maximum outputs are 189kW of power and 370Nm of torque.

It’s very responsive with its power output and you definitely will be surprised by how much grunt this thing has.

Drive goes to the front wheels via a 10-speed auto transmission but it’s clunky and a bit too slow to shift out of the lower gears. This can make it feel like the engine is pulling back even when you’re accelerating, which I didn’t like.

On the electric motor side of things – the lithium-ion battery has a 16.6kW capacity and 63km (NEDC) driving range.

It has a Type 2 AC charging port but it can’t be hooked onto a fast charger as it lacks the CCS enhanced port. On a 7.0kW system you should see a full charge be completed in around five hours.

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.

With the electric motor being used, the official combined cycle fuel figure is 1.7L/100km and the urban figure comes out at 5.8L/100km.

My real-world usage came to 6.6L. That’s not bad at all, but I have done a lot of open-road driving this week. 

Based on the urban figure and the 55L fuel tank, you should see an approximate driving range of 948km.

MG recommends a minimum 95RON petrol be used. 

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. 

I’ve been pleasantly surprised by the overall driving experience. Besides the slower gear shifting, it’s generally smooth to handle. The power is there and makes it easy to keep up with traffic or overtake if you need to.

The suspension handles bumps very well and the steering is responsive. You can tackle corners or a winding road with confidence and without too much roll!

The cabin is quiet, even at higher speeds but you will note the whining of the engine at lower speeds as those gears shift.

On a windy day at higher speeds, the car moves about in the lane more than I like but otherwise, is firmly placed.

The regen braking isn’t customisable but it’s firm enough that you’ll feel it when you pull off the accelerator.

Going down a mountain let me gain five per cent charge on the battery and despite driving over 500km this week I only popped it on charge once (with 15 per cent left) - just to give you an indication of its performance.

I kept the EV mode on default but you can switch it over to a full EV if you want to wring out the most from the electric range.

This is not a difficult car to park and you’ll love its size in a small car park. However, the 360-degree camera view, while pretty clear, is jumpy.

At first, I thought it was laggy but the image just shudders, like a bad connection. I's prefer to see front parking sensors, too, as this MG only has them at the rear.

The safety features are good on the HS and I like the 360-degree camera view but don't like the way the image shudders while in use.

It has a blind-spot monitoring system but the interior ‘alert’ light is in a blink-and-you’ll-miss-it position.

Other features that come standard, are LED daytime running lights, forward collision warning, rear cross-traffic alert, lane keeping aids, lane departure warning, intelligent seat belt reminders, rear parking sensors, traffic sign recognition, a driver fatigue monitor and adaptive cruise control.

It has autonomous emergency braking with car, pedestrian and cyclist detection which is operational from 0-80km/h.

The HS +EV hasn’t been assessed by ANCAP but its fuel-based sibling achieved a maximum five-star rating in 2019.

It only has six airbags, which is pretty low for an SUV, but the curtain airbags cover the back row.

There are ISOFIX child-seat mounts on the outboard seats and three top-tether anchor points but two seats will fit best.

Front passenger space may be compromised a little when a 0-4 rear-facing child seat is installed but overall, it was very easy to install my booster seat this week.

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 ongoing costs are great on this! It comes with a seven-year/unlimited km warranty, which includes the hybrid battery.

It also has a seven-year capped-price servicing plan, which is above average for the class, and services average $426 which is competitive.

Servicing intervals are every 12 months or 10,000km, whichever occurs first, which is fine if you don’t clock a lot of kays every year.
