MG MG3 vs BYD Seal

What's the difference?

The MG3 still makes a strong argument for a low-cost, low-fuss option just like the models it now beats on price (Yaris, Mazda2, etc) used to.

While it also falls short in some areas like dynamics when pushed, the improvements to interior tech and comfort mean the MG3 should be considered if you're looking for a city runabout.

However, with the MG3’s price jump, rivals from Japanese and Korean brands are closer in cost than they were for the sub-$20K first-gen MG3, and their ability to handle Australia’s conditions outside the city mean they’ll prove a more useful long-term companion for many.

The MG3 nails its brief as a convincing option for first-car buyers or as a second runabout when there’s another option for long trips. It has taken a big step up from the ‘budget-friendly’ vibe of the original.

Those big auto executives have good reason to be worried, because the Seal is yet another impressive offering from China’s most formidable EV player.

It’s not perfect. In some ways it’s trying too hard to be a luxury car, and I think the software in particular could use a little work, but the Seal just does so much right I think it will be hard to be disappointed with one, particularly given its keen entry price.

In fact, if we had to pick one from the range, it would probably be this mid-spec Premium. The range and power on offer are stellar, and all for less money than an entry-level Model 3 or Polestar 2.

Following the new design language pioneered here by the MG5 sedan and MG4 electric hatch, the MG3 looks like it’s trying for a sportier vibe than its predecessor, and maybe even a hint of European flair.

A grinning front grille and pointed set of headlights are followed around the side by a couple of body creases that give the hatchback a sweeping look, an attempt perhaps to seem longer than it is.

It doesn’t look like any of its rivals, unlike the MG5 which is easily mistaken for a small Mercedes CLA at glance.

Here on our Dover White test car, some angles are unflattering (it's giving 'hire car'), though the model’s available Diamond Red or Brighton Blue are fairly distinctive. Yes, some of the colours reference the brand’s UK heritage, despite being built in China.

Inside, the cabin benefits from a fairly tidy layout, with some genuinely thoughtful attempts at making the otherwise budget-focused model feel a little nice. A cross-hatch design through the dash mirrors, the seat stitching and the steering wheel and its buttons are nicely angular.

The Seal looks great. It’s about as modern a take on the traditional three-box sedan as you can get. It’s low-slung with curvy lines and a sporty overall feel.

The design touches, like the headlight and DRL surrounds, side skirts, and wheels are maximalist compared to the minimalist vibes of the Model 3 and the Polestar 2. But I don’t necessarily think that's a bad thing as it offers buyers a genuine alternative.

I also like the way the brand has executed the LED lights and particularly the tail-light fittings. There’s also an admirable restraint when it comes to badging compared to a lot of this car’s Chinese rivals. It doesn’t give off the vibe of a cut-price product at all.

Inside there are elements which are appealing, and some things which fall short. First up, I do think the Seal wears its influences throughout the industry on its sleeve a bit.

The digital dash cluster theme, for example, seems to (poorly) emulate the Mercedes-Benz software, the little plastic crystal shifter piece on the inside seems to have been overtly influenced by a similar (actual crystal) piece available in Volvos, while the centre screen and dual wireless phone chargers are pretty obviously BYD’s take on the similar bits available in the Model 3.

Maybe in this sense, it’s trying a little too hard to be a luxury car and a tech-heavy electric vehicle, with items which aren’t quite up to the same quality (particularly the software). But then, it all works well enough, and can you complain at the price?

One thing I think BYD gets right though is the level of comfort on offer in the cabin and the clever little styling bits which remind you of its namesake.

The door handle pieces and integrated speaker bits are shaped like a Seal flipper. As are the dash-mounted air vents, and if you look closely even the plastic garnish on the steering wheel looks a bit like a top-down cross section of the animal.

I like it because its subtle rather than in-your-face as some of the Atto 3's design elements are.

The quality is also up to muster, big time. There wasn’t a creak, groan, or rattle from this car’s interior in my entire time with it, including on some of Sydney's worst roads. And the seats, which are designed like absolute thrones, are clad in lovely soft leather. You sink into them. Even the two-tone Alcantara finish through the doors and centre console is thoughtfully placed.

That tidy design inside helps when it comes to making use of the space, as well as offering some generous storage spaces.

For starters, while the clean layout means the screen looks like the main point of access for much of the car’s function, there’s an all-important shortcut button for the climate control which means you don't waste time navigating to the vent and temperature controls.

The only issue is that while my phone was connected to the system for Android Auto, I had to navigate away from the mirroring screen back to the MG3’s home screen before being able to shortcut to the climate settings.

Demister and volume control buttons are also present, but the screen itself has an easy-to-navigate menu.

The steering wheel controls are similarly straightforward and clearly labelled, while the driver display is tidy and shows important information clearly.

While the steering wheel isn’t telescopically adjustable, it's easy to find a comfortable seating position thanks to the adjustability of the seats. The material on the seats doesn't feel rough or cheap.

Behind that, there is enough space for my 178cm frame in the second row for the most part, but headroom isn’t incredibly generous.

The rear pew is a single unit, rather than a 60/40 split, so the whole backrest folds down if you need to load anything long through the boot. There’s not even an armrest or little ski hatch for long, thin items.

Its 293-litre boot isn’t small, and there’s a space-saver spare tyre in both petrol variants, but the hybrids are stuck with repair kits.

The Seal has a huge cabin, and in a lot of ways it feels like the large sedans of old. You can sit nice and low in the cabin, and there’s heaps of knee and headroom thanks to its width.

Soft-clad materials for resting your knees and elbows on go a long way towards keeping this car comfortable on longer journeys, and the presence of a digital dash and a holographic head-up display is nice to have compared to the bare-bones dash of the Tesla Model 3.

The wacky rotating central touchscreen feature makes an appearance from other BYDs, but again, it’s a bit silly and I’m not sure how much use you’ll get out of it. Even Apple CarPlay only works in landscape mode, so I didn’t find it useful.

Practicality features are abundant, with a large bottle holder in the doors, and two more in the centre console. One even has a floating floor, so you can push it down to accommodate large bottles if need be.

Dual wireless chargers are always a nice touch, and the bridge-style console has a large pass-through storage area underneath, which also hides the USB-C, USB-A, and 12V outlets. The armrest console box is nice and deep, too.

The back seat is enormous. Possibly one of the largest spaces in this segment. It comes at a cost to boot capacity, but your rear passengers won’t want for space no matter how tall they are.

At 182cm tall I had leagues of airspace behind my own driving position, and the wide cabin, accommodating seats, and flat floor mean the centre position is even useful for a full-sized adult.

Storage comes in the form of three pockets on the back of each front seat, a large bottle holder in the doors, two cupholders in the drop-down armrests, a small tray on the back of the centre console, and a small flip-out cover which reveals a USB-C and USB-A charging port for rear passengers. The rear seat even gets dual adjustable air vents, but no third climate zone.

The massive fixed glass roof looks the business and keeps the cabin airy, just like in the Model 3 and Polestar 2, but I find these big glass fittings tend to cook interiors in the Australian sun.

BYD tells us the tint is so heavy it has a ‘solar transmittance’ of just 16 per cent, but 16 per cent is still a lot in Australian summer. Thankfully, unlike its two rivals, BYD ships the Seal with a fold-out cover screen as standard.

Remember how I said the massive rear seat comes at a cost to boot space? At 400 litres the Seal’s boot is a bit compact, made worse by the fact it’s a sedan and not a liftback, so the access area is a bit narrow.

It could only fit the largest CarsGuide luggage case alongside the smallest one, but not all three including the medium case. This could be a blow to family buyers who need to fit a pram alongside other things.

Under the floor there’s an extra space great for the storage of your V2L adapter and AC charging cable, but there’s also only a tyre repair kit and no spare.

Just like its Model 3 rival, the Seal arrives in Australia in three variants - the base Dynamic, top-spec Performance, and the one we’re looking at for this review, the mid-spec Premium.

Price is, of course, BYD’s forte, with this mid-spec Premium (equipped with a long-range battery) even managing to undercut the entry-level Model 3 RWD.

Before on-road costs and state-based incentives you can have one of these from $58,798, while (at the time of writing at least) the enormously popular Model 3 RWD weighed in at $61,900. Its next closes rival, the Polestar 2 Standard Range, costs from $67,400, so value here is obvious.

The Premium’s long-range battery allows a WLTP-certified driving range of 570km between charges which is even one of the longest cruising ranges available on any electric vehicle in Australia right now.

The list of standard features is exhaustive, including 19-inch alloy wheels, LED headlights, a massive 15.6-inch multimedia touchscreen with wired Apple CarPlay and wireless Android Auto, a 10.25-inch digital instrument cluster, a holographic head-up display, dual wireless phone charging bays, built-in navigation and connected services, ‘genuine’ leather seat and wheel trim (a blend of synthetic and real leather), an eight-way power-adjustable seat for the driver, ventilated and heated front seats, dual-zone climate control, a fixed panoramic glass roof and keyless entry with push-start ignition.

The Seal also gets an impressive array of standard safety kit. More on this later.

The only options are premium paints and an alternate light blue theme for the interior which cost $1500 each.

This list of kit would even be impressive on a combustion car at this price, so the fact it’s also electric and offers one of the longest driving ranges on the market is a bonus.

The one area where I think it lacks a little is the stock software. It looks okay and, to be fair, functions a lot better than its Chinese contemporaries and even some other brands, but once you dig into it a little there are some clumsy menus, and it becomes painfully obvious it’s a simple Android reskin. A swing and almost a miss for something so integral to a car like this.

Why is it called the Seal? Well, in BYD’s home market of China, its range is so expansive it has split it up into two model lines, the Dynasty series (named after historical Chinese kingdoms) of which the Atto 3 is a member (it is called the Yuan Plus in China), and the Ocean series which the Seal and Dolphin belong to. The next BYD to arrive in Australia, a mid-size SUV likely to be called the Seal U, also belongs to the Ocean series.

On paper, the MG3’s 1.5-litre four-cylinder engine is fairly underwhelming with its 81kW (peaking at 6000rpm) and 142Nm (at 4500rpm).

But these figures, including the engine size and even peak RPMs are not far off the likes of the Mazda2, which is a fairly peppy and fun car despite its lack of grunt.

Keen drivers will, however, be disappointed to hear the MG3 drives the front wheels via a continuously variable transmission (CVT) rather than a traditional torque-converter auto, taking much of the pep out of its power unit.

You can expect to hit 100km/h in a bit over 10 seconds.

Each Seal variant gets its own drivetrain outputs, and the mid-spec Premium drives the rear wheels with a 230kW/360Nm electric motor via a reduction gear.

On paper, it’s slightly more powerful than the Model 3 RWD, with more power and less torque than the Polestar 2 Standard Range.

MG claims the MG3 uses just 6.0 litres of 91 RON petrol every 100km on the combined fuel cycle, so with its 45-litre tank you can hypothetically bank on a 750km range.

Of course, that might be achievable in lab conditions, but on test we found the trip computer’s estimates looking closer to 500km on a tank for the kind of urban driving it was undertaking with us.

On a dynamic test drive route, the trip computer settled at a displayed consumption figure of 7.7L/100km, but stop-start driving was not great for efficiency, as you'd expect.

Providing power is a sizable 82.56kWh lithium-ion battery pack, using BYD’s signature weight and space-saving ‘Blade’ form-factor, and the more affordable LFP (lithium iron ferrophosphate) chemistry.

On the charging front, the Seal Premium can top up at 150kW on a DC unit (using a Type 2 CCS connector) for a 10-80 per cent charge in roughly 40 minutes, while on AC its a disappointing 7.0kW.

The 7.0kW inverter means it’s hardly worth plugging the Seal in at a slow public charger when you visit the shops, as you’ll only get about 50km of range an hour. It’s for this reason most cars with batteries this size have 11kW inverters.

Unlike the Model 3 or Polestar 2, though, the Seal features a V2L system, allowing you to power household appliances from its Type 2 charging port.

Claimed energy consumption for the Seal is 14.6kWh/100km which is low, and about what we were seeing on test. It’s a little hard to tell because the trip computer only offers total consumption over the entire life of the vehicle, or for the last 50km, but not for a set trip interval. Weird.

The higher quality look and feel of the new MG3 carries through to its day-to-day driving. Some of the car’s Chinese compatriots seem to fall down when it comes to the on-road part, which for some is the most important part of a car.

But for a small city car the MG3 is very user friendly, with light and direct steering, good visibility, and just enough power and torque to not feel like everyone’s getting the green light a couple of seconds earlier than you.

It’s comfortable at urban speeds when it comes to the suspension, and doesn't get rattled too much in the front end by tram tracks or other road imperfections.

In narrow streets, three-point turns aren’t a hassle and the car’s size means it’s easy to reverse parallel park, although the reversing camera takes a second to appear when using phone mirroring.

On the highway, however, and when it comes to high-speed cornering, the MG3 can feel a little uneasy.

The road noise becomes more and more obvious. Driving on well-maintained metro freeways at around 80km/h or above produces unpleasant noise, and a during a particularly breezy week the car felt susceptible to swaying in high wind.

Its power delivery starts to feel lacking out of town, too, and taking corners on fast back roads means plenty of slowing down to avoid the front-end sliding or the feeling of the MG3 leaning unsettlingly around corners.

If you’re considering the MG3 but you need to head out of town regularly, take a proper long test drive before opening your wallet.

But if you just need it as an urban runabout, the MG3 does a fine job.

I wasn’t expecting the Seal to impress me particularly. After all, it’s in this segment against tough competition, amongst recently updated versions of the Model 3 and Polestar 2, and while the previous BYDs I’ve driven have been a cut above their Chinese contemporaries, they also haven’t done a lot to stand out from the crowd.

Clearly, though, BYD has something to prove with its sporting sedan and the Seal is immediately impressive. The cabin is quiet and refined, the seating position is great it's smooth from take-off.

The steering has an artificial tinge to it removing a bit of feedback from the road, but proves at least quick and accurate at speed, and the handling is superb.

I kept pushing the Seal in my test drive, expecting gnarly characteristics to surface but they didn’t. This sedan grabs onto the road with excellent control and traction at the rear, spurred along by its long wheelbase, and improved tyre choice (Continental rather than the sub-par Chinese rubber worn by the Atto 3 and Dolphin).

While on paper it appears to have at least comparable motor output figures to the Polestar 2 and Model 3 - the Seal Premium doesn’t quite feel as rapid, its electric motor having a more relaxed vibe and responsiveness when you stomp on the go pedal.

This can be tweaked a little by dialling it up to Sport mode, and while it still doesn’t feel quite as breakneck fast as the Model 3, in particular, it’s plenty to be going on with.

The most impressive part of the Seal drive experience, though, is its ride. Ride is a constant problem for EVs as manufacturers go to lengths to tame the additional weight of batteries, but the Seal is the most impressive in its cohort, and by quite a margin.

It’s firm enough to be controlled, but has a lovely soft edge to it, so larger bumps, frequent corrugations, or sharper road imperfections don’t ruin your day.

The Model 3 and Polestar 2, even in their improved forms, are not this good. In a lot of ways the Seal’s suspension tune reminds me of the Mustang Mach-e. It has a soft edge, offset by a bit of secondary jiggle as the car settles, which is its only real blemish.

The Seal has no right being this good. It’s now not just matching its far more established rivals but doing some things significantly better.

The Seal has an extensive list of today’s active safety equipment, including auto emergency braking (front and rear), lane keeping aids, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control, traffic sign recognition and driver attention alert.

For the most part, these systems aren’t invasively annoying, which can’t be said for many products from rival automakers.

However, the traffic sign recognition and overspeed warning system conspire to intrude with constant beeping.

Mercifully, and unlike the equivalent system in Hyundai products, it’s a distant beep, but a consistent one nonetheless, as the traffic sign system frequently picks the wrong speed for whatever reason, and then chastises you for going over it.

Also, the adaptive cruise control system can’t hold a candle to the Model 3's. The system in the Seal amounts to the usual sort of adaptive cruise in most other cars, whereas the one in the Model 3 (regardless of how you feel about the brand’s outrageous claims) is properly next-level in its lane keeping and distance controls.

The Seal is equipped with seven airbags and was rated a maximum five ANCAP stars to the 2023 standards.

MG has a 10-year/250,000km warranty which is unmatched in the small-car market.

Servicing is scheduled at every 10,000km or 12-month intervals, with the first seven services averaging out at a fairly hefty $360 - the cheapest being $234 and the priciest $536.

The long-term ownership aspect for a BYD product is still a bit of a mystery as the current crop of cars have only just landed in Australia in the last year or two, but if it offers you any peace of mind, the Seal is covered by a six-year/150,000km warranty with a separate eight-year/160,000km warranty for the battery pack.

In order to avoid having to have a traditional dealer network, BYD has partnered with MyCar to fulfil servicing. Visits to one of these locations is required once every 12 months or 20,000km whichever comes first, and pricing is fixed for the first eight years, working out to an annual average of $299.
