BYD Sealion 6 vs MG MG5

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 MG5 works well as a budget-friendly small car, and it’s genuinely good to drive.

Some small let-downs in terms of packaging don’t detract from this car in any major way, but the lack of active safety is a concern considering the features most of its rivals offer.

If it’s on your shopping list, make sure you know what else is on offer in terms of safety before you lock in the MG5 for the savings.

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.

The MG5’s styling might be a little divisive, with the overall shape and look of the small sedan sitting somewhere between its direct rivals, like the Hyundai i30 Sedan, and aspirational models like the Mercedes CLA.

In this Essence variant, the grey insert for the grille gives the front a darker, more aggressive look, though the way the grille mesh weaves makes it look a little like moustache hair.

The large ‘intake-style’ design at the sides gives it a sportier look than its outputs have perhaps earned - not to say the MG5 is sluggish - and following those around to the side of the car leads to a fairly minimalistic and tidy silhouette.

Here, probably most notable is the rather tall gap between the tyres and wheel arches.

The rear, with that sloped-up roofline, transitioning into a gentle lip spoiler, flanked by those lights, is where CLA fans might have the most to say about the MG5’s design.

Notably, the exhaust vents at the bottom are fake. The real exhaust exit is hidden well underneath.

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.

Some newer brands to Australia, often MG’s compatriots from China, get some of the ergonomic or tech basics wrong as they focus more on an impactful first impression. Fortunately, MG doesn’t do that, for the most part.

Inside the MG5 is a cabin that looks more expensive than it is, but has some useful features to back it up without the superfluous add-ons.

Aside from the lack of physical climate controls - an annoying cost-saving or interior-tidying trend embraced by brands from budget to bougie - the MG5’s interfaces and ergonomics are pretty sensible.

Accessibility ticks for the steering wheel buttons being few and large enough to use without needing to look, as well as the lack of a panel of buttons and switches in the centre console. Looking at you, BMW.

The screen is also functionally sound, with obvious menu layouts and fairly large buttons as touch points, so it doesn’t feel like trying to operate a tablet while you’re driving.

It does, again, lose points for the climate control situation, which weirdly features a temperature slider as a colour gradient rather than numerical temperatures.

No wireless phone charger means needing space for a plugged-in phone, which the MG5 has just enough of, though similarly ‘just enough’ is the size of the cupholders, which won’t fit a big water bottle.

In the rear, there’s space enough for an adult to sit comfortably behind another adult, though it’s not the place for long journeys.

Strangely, there’s only one central vent control in the rear so only one passenger gets cool air or heat, plus there isn’t a great deal of storage. No armrest or cupholders for rear passengers, either.

Also noteworthy is the single-piece rear seat, which means if longer items need to be transported in the 401-litre boot, the whole rear seat must be folded down and the MG5 temporarily becomes a two-seater.

Under the boot floor is a space-saver spare, though, so bonus points for a more useful addition than a simple repair kit.

MG has managed to cram quite a bit into the MG5 for less than $25K drive-away in its Vibe entry-level variant.

More specifically, you’re forking out $24,990 to head off from the dealership in one, even with its missing active safety features, but we’ll come back to that.

In Vibe specification, the MG5 comes with 16-inch alloy wheels, auto LED headlights, a reversing camera and a tyre pressure monitor, while inside you’ll find a 10.0-inch touchscreen with Apple CarPlay and Android Auto capability (both wired) with four speakers for the sound system, as well as a push-button start, synthetic leather seats and three different selectable steering modes.

Stepping up to the Essence, which we’re testing here, costs $28,990 drive-away and adds a sunroof, a six-speaker sound system, electric seat adjustment for the driver, steering wheel paddle shifters - for a reason we’ll return to - and turns the rear-view camera into a surround-view parking camera.

The Essence is also visibly different on the outside thanks to slightly larger 17-inch alloys, auto-fold (when locked) side mirrors, and a grey grille insert rather than body-coloured.

On that, you can have white or yellow as no-cost paint colours in either MG5 variant, but metallic red, blue, black or grey are all $700 options.

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 versions of the MG5 come with a 1.5-litre four-cylinder engine that drives the front wheels, but the similarities mostly end there.

In the entry-level Vibe, that engine is naturally aspirated and makes 84kW and 150Nm - similar to the MG3. Power is transferred to the front wheels via a continuously variable transmission (CVT).

In our Essence variant the engine is turbocharged and makes a suitably higher 119kW and 250Nm, driving the front wheels via a seven-speed dual-clutch automatic transmission.

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 naturally aspirated Vibe's official combined cycle fuel economy figure is 5.7 litres per 100km, while the turbocharged Essence drinks a little more at 5.9L/100km.

For comparison, Toyota claims its non-hybrid Corolla Sedan will sip 6.0L/100km, while a Mazda3 Sedan claims 6.1L/100km. Not bad, then, if you can keep it near MG’s claim.

During our testing, with a mix of city, suburban, highway, and rural driving, the MG5 Essence burned through 95 RON premium fuel at a rate of 9.1L/100km, checked at the pump, though I wouldn't expect this to be representative of normal, calmer day-to-day driving.

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. 

Perhaps the biggest surprise about the MG5 is that it’s quite good to drive. And not just ‘for an MG’ or ‘for a car from China’. It’s actually good.

The turbocharged engine takes a moment to get going, and the dual-clutch can be a little hesitant off the mark.

The combo of the two means sometimes you need to plan your take off ahead of time - but in its above-3000rpm sweet spot, the Essence has a good bit of urgency to it.

That’s fortunately paired with a combination of comfortable suspension and a composed chassis, with well-weighted steering.

On urban roads and with a little awareness of the slow take-off, the MG5 is capable and well-suited to small roads, though it can be a little frustrating in stop-start traffic.

On the other hand, outside the confines of city driving, the small sedan is more dynamic than you might expect, able to get up to speed and comfortably overtake on highways, as well as handle corners on twisty roads confidently.

Potholes and rough sections of road don’t rattle the MG5 as much as you might expect from a car in this segment, though road noise can be a intrusive on coarse roads - of which Australia has many.

Dare I say it - the MG5 is rather fun.

Here’s the bit that might turn potential owners off the MG5. Or here aren’t the bits, more accurately.

The MG5 comes with a short list of safety features that amount to the minimum standard for a car to be sold in Australia.

That is, six airbags, autonomous emergency braking (AEB), anti-lock brakes (ABS) and electronic stability control (ESC).

MG also lists hill-hold under its safety features, as well as its active cornering brake control and auto door unlock and activation of hazard lights in case of an accident.

There are also ISOFIX and seat tether points for the outer rear seats.

The reverse camera in the Vibe is replaced by a surround-view camera in the Essence, though the visual quality of the feed leaves a bit to be desired.

Crucially, it’s missing a host of safety features that would be standard, or at least optional on a rival like the Toyota Corolla Sedan or Mazda3 Sedan, like steering assist, a pre-collision safety system, pedestrian detection, active cruise control and even lane departure alert.

Rear cross-traffic alert and blind-spot monitoring? Nope.

MG Australia CEO Peter Ciao told CarsGuide not long ago it’s about keeping the price of the car accessible for more customers, which means you’ll have to make your own call regarding whether it’s safe enough for you.

To that, ANCAP hasn’t crash tested the MG5, but if it did we wouldn’t expect it to score any higher than three stars.

While we don’t know how it would hold up in the area of crash protection, it lacks too much of the active safety gear that ANCAP expects of a maximum five- or even four-star car.

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.

MG offers a seven-year/unlimited kilometre warranty on the MG5 as with all its models - even electric cars. That also comes with roadside assist for the duration of the warranty, though only 160,000km is covered by the warranty if the car is used for commercial purposes.

Servicing prices for the MG5 range from $266 or $272 for the Vibe or Essence, respectively, up to $581 or $661 for the most expensive of the seven 10,000km/12-month scheduled services.

The total cost of servicing the Vibe over its seven years under capped-price servicing comes to $2661, or about $380 average per service. For the Essence, that bumps up to $2764 or an average of about $394 per service.
