BYD Sealion 5 vs MG Mg7

What's the difference?

Cars that don’t always appeal to enthusiast buyers are often seen by manufacturers as a way of not bothering with the dynamics. Good enough is, apparently, good enough. Thankfully, BYD hasn’t taken that path here and the local suspension tweaks have turned what could have been a me-too product into a bit of a dynamic class leader. And even if buyers can’t verbalise the benefits of that, they will still be subliminally enjoying them with every kilometre.

The other stand-out feature is the price-tag which represents an awful lot of car for the money. And, in such a price-sensitive market as this one, that will get the BYD over the line for a lot of families. That it also offers a vastly better driving experience simply makes the value equation – and the purchasing proposition – even stronger.

In a world obsessed with SUVs and electric powertrains, a mid-size petrol sedan almost feels rebellious. But the MG7 kind of is. A sleek fastback with a turbocharged engine, a sporty edge and a price that makes you look twice - it’s a compelling combination. There are some drawbacks for families in efficiency and back-seat practicality but it's not a bad offering for those wanting something a bit more fun than an SUV.

The interior of the Sealion 5 feels pretty well-made and there are soft-touch surfaces on most of the touch-points. The steering wheel, too, is thick and chunky and nice to hang on to. But there’s a lot going on in terms of different colours, textures and surfaces, and it can all look a bit busy, despite the high-tech boardroom overall flavour. It’s also worth mentioning the trim material is synthetic but does a great job of looking and feeling like real leather.

Externally, there’s not a lot to grab the eye. Sure, it’s not an unpleasant looking vehicle, but neither does it stand out from the mid-size SUV pack. At least BYD decided against those cheap-looking plastic tack-ons on each wheel-arch.

The MG7 is genuinely good looking. The fastback roofline gives it a sleek silhouette, and there’s a confidence to the way it carries itself.

The blacked-out badging, quad exhaust outlets, 19-inch Michelin tyres and red brake calipers all lean into that sporty brief. It looks fast standing still. The frameless doors are a nice touch, and the retractable rear spoiler adds a bit of theatre and fun.

Inside, the cabin follows through on that upmarket intent. Deep burgundy leather and synthetic suede are used generously throughout, giving it a sumptuous feel. Although, my husband joked that he wouldn't be able to drive it during State of Origin... sorry, Queenslanders!

There’s less reliance on piano black trim, which I appreciate as it scuffs easily, and most surfaces look well-finished. The integrated headrests up front give the illusion of proper sports seats but I do wonder if the interior would pop half as well if it was finished in the optional black.

The dashboard is dominated by a wide digital display incorporating a 10.25-inch instrument cluster and a 12.3-inch media screen. The panoramic sunroof helps keep things light and airy, and while there aren’t many physical buttons or dials, which is usually a gripe of mine, the overall execution feels cohesive and premium for the price point.

Here’s the other big shock relative to the price-tag of the Sealion 5: This is not a small car. Based on the price, you might have been thinking the vehicle would be a compact SUV. And you’d have been wrong. This is a proper mid-sized SUV with room for five and luggage and an overall length of 4.7 metres and change. And to put that into some kind of perspective, that’s just 30mm shorter than the Sealion 6 which costs about $9000 more at its starting point.

The wheelbase is long, too, and the 2712mm between the axles helps make the interior even more spacious. That means there’s lots of stretching room in the front, but also that a grown adult can comfortably sit in the back seat behind another grown adult at the wheel and still have enough room in every direction. The window sills are commendably low in the rear seat, too, ensuring even littlies can see out.

The biggest problem in the back is that the seat cushion is a bit flat, but, like the front chairs, it’s still pretty plush.

With all five seats in place, the Sealion 5 boasts 463 litres of luggage space and the cargo area is well done with storage pockets at each side, a light and an under-floor tray designed to transport charging cables and a tyre repair kit. Yep, that’s right, there’s no spare tyre of any sort here. No surprise, really.

Fold the rear seat down and you’re suddenly looking at 1410 litres of cargo space and your SUV is now a panel van.

As well as the dual-zone climate control, the Sealion 5 also offers a single USB -C and a USB-A charging port in the front and rear compartments.

The Sealion 5 also offers a V2L (Vehicle to Load) function, meaning it can power camping or on-site work equipment and even act as your home’s battery.

Up front is where the MG7 feels most generous. The electrically adjustable front seats are comfortable and supportive for daily driving, although extendable under-thigh support would help reduce fatigue on longer trips. You do get heating for both the seats and the steering wheel but having to dive into the media menu to activate them is annoying.

In the second row, legroom is respectable for a mid-size sedan. Headroom, however, is tighter thanks to the fastback roofline and panoramic sunroof. Tall teenagers won't feel like they can sprawl out but younger kids will be fine. The second row features two ISOFIX child seat mounts and three top-tether anchor points but two child seats will fit best. Bending down to buckle in a child will remind your back why SUVs became all the rage, but it's certainly doable.

The seats in the second row are thickly padded and comfortable, and the fold-down armrest sits at a good height to lean on. Amenities aren’t especially extensive given there’s only one grade available, but you do get a couple of cupholders, map pockets, directional air vents and two USB-C ports.

Storage in the front row is about what you’d expect for a car of this size. There’s a decent glove box, a shallow middle console, large door bins and some handy little nooks near your knee. A sunglasses holder and a dedicated phone cradle with wireless charging round things out nicely. The wireless charger can lag a little in topping up your battery, and it's quick to overheat your phone - added ventilation would be a big help here. However, there’s also a 12-volt socket and two USB-C ports if you prefer a cable.

The media system itself is responsive and largely intuitive, although the touchpad-style controls on the dash feel slightly back-to-front in use. On the plus side, it’s very easy to flick into Sport mode and open up the exhaust using the cluster controls, which adds a bit of fun to the daily drive.

The boot offers 375 litres of capacity, which is on the smaller side for the segment. Comparatively, the Sonata N Line offers 480L, the Skoda Sportline 600L and the Camry 524L. That said, it’s been perfectly usable for grocery runs and the odd road trip this week. You do need to load bulkier items further back toward the seats to work around the sloping fastback design. A powered tailgate adds convenience, and there’s a temporary spare tyre underneath, which I always prefer to a repair kit.

For now, the MG7 is offered in a single grade, the Essence, priced from $44,990 before on-road costs.

That positions it just above the Skoda Octavia Sportline, which starts from $44,490 MSRP, although the Skoda doesn’t match the MG7 feature for feature. In terms of features and styling, it’s closer to the Hyundai Sonata N Line, which opens at $56,500 MSRP. And then there’s the segment darling, the Toyota Camry SL, from $53,990 MSRP, happily flexing its hybrid efficiency credentials.

On price alone, the MG7 looks competitive. On specification, it starts to look like a bit of a statement. You get leather and synthetic suede upholstery, heated and electrically adjustable front seats, memory function for the driver’s seat, a heated steering wheel, a panoramic sunroof and 19-inch Michelin tyres.

Technology feels well thought out and a large centre display houses a 12.3-inch media system, paired with a 10.25-inch digital instrument cluster that appears larger than it is thanks to the integrated touch controls. There’s wired and wireless Apple CarPlay and Android Auto, built-in satellite navigation, 256-colour ambient lighting and a 14-speaker Bose sound system.

Practicality hasn’t been overlooked either. A powered tailgate, temporary space saver spare wheel, dual-zone climate control, acoustic door glass, rain-sensing wipers and a 360-degree camera system round out the package.

Both variants of the Sealion 5 have the same driveline – mostly. They each use a 1.5-litre petrol engine teamed with a single electric motor, both driving the front wheels. Unlike the bigger Sealions, there’s no all-wheel drive version. Power peaks at 156kW and torque at 300Nm.

Why a non-turbocharged engine? BYD tells us the non-turbo engine helps keep cost out of the vehicle and, since the engine really only runs to power the electric motor and charge the batteries, it does so at a relatively constant engine speed, negating the need for a wide spread of petrol power.

The only major difference is that the Essential version has a 12.9kWh battery-pack, while the Premium gets a bigger, 18.3kWh pack for longer range, but precisely the same output and, therefore, performance.

A single-speed transmission is part of the BYD driveline package, also made possible by the fact that the vast majority of the driving of wheels is done by the electric motor.

The MG7 has a 2.0L, four-cylinder turbo-petrol engine producing up to 170kW of power and 380Nm of torque. That’s pretty gusty compared to its nearest rivals, although the Sonata N Line still beats it with its 213kW/422Nm outputs. The Hyundai is more of a dedicated sports model. Still, with these outputs the MG7 manages a 0 -100km/h sprint in a swift 6.5-seconds!

Power is delivered to the front wheels and the nine-speed auto transmission punches through its gears relatively smoothly. You can also flip it into Sport mode, where gear changes become more pronounced.

Overall, the whole setup creates an engaging on-road experience without lulling you into any false pretences. The MG7 is not a racer, even though it looks like one, but it holds its own.

The Premium’s bigger battery claims to up the official NEDC range from the Essential’s 71km to 100km. BYD reckons with the 52-litre fuel tank brimmed and the car operating at its claimed 1.2 litres per 100km efficiency, the range of either version is just on 1000km. In the real world, that’s likely to be closer to 800km (especially with some highway running thrown in) but it’s still one heck of a solution to range anxiety.

There’s no DC charging function for the Sealion 5, so forget about commercial fast chargers. But on a 3.3kW AC power outlet, the maker claims the Essential can reach full charge in under four hours, while the Premium’s bigger battery will take under six hours to fully charge. A Type 1 charge cable is included.

The MG7 has a claimed combined fuel consumption figure of 8.0L/100km. With its 65-litre fuel tank, that equates to a theoretical driving range of up to 812km.

That places it broadly in line with the Hyundai Sonata N Line, which claims 8.1L/100km, although the Hyundai delivers stronger engine outputs. The Skoda Octavia Sportline is notably more frugal at 6.1L/100km, while the Toyota Camry SL continues to dominate the efficiency conversation with its 4.0L/100km hybrid figure.

In real-world driving, expect that 8.0L/100km claim to creep up. Even after a week consisting mostly of longer highway stretches, my trip computer was sitting at 8.6L/100km. That’s not wildly unexpected for a turbo-petrol engine, and it’s hardly alarming, but efficiency is a major consideration for families. Against hybrid rivals, it doesn’t win that particular argument.

Combined CO2 (ADR 81/02) emissions sit at 183g/km, which is comparative to the Hyundai Sonata N Line but not as low as its other rivals.

MG recommends a minimum 95 RON unleaded petrol to be used.

You don’t have to drive very far to realise that the local input into the Sealion 5’s suspension and steering have been worth the effort. BYD Australia has a local engineering team on call these days, and it shows here.

Actually, the steering is not the highlight; it has some weight but not a whole lot of feel, or, indeed, feedback for the driver. The ride and handling combination is what stars. Obviously well-damped, the suspension allows for a ride that is both complaint and quiet, without causing the car to wallow around like some jacked-up designs can with their higher centre of gravity.

In fact, the BYD is athletic to the point where keener drivers will find it an entertaining drive; hardly something that can be said for the majority of medium SUVs.

Performance is strong without being overwhelming and even though the Sealion 5 has that signature electric-drive feeling of effortlessness, the accelerator pedal has been calibrated to avoid the neck-snapping surge of grunt off the line. As such, it emerges with a fairly flat acceleration curve, and no hint that the petrol motor is cutting in or out.

Until, that is, you bury the throttle all the way at which point the petrol engine takes a few second to join in. And when it does, it’s pretty vocal – shrill, almost – as it catches up with the rest of the car and starts directly driving the wheels. To be fair, though, this is not going to be a common occurrence in everyday life thanks to the flexibility of the petrol-electric system for 99 per cent of circumstances.

On the move, the cabin is perhaps most notable for its soft, plush seats that are a nice change from the church pews of some manufacturers. And although the driving position is about right, taller drivers might prefer a steering column that extends out another few millimetres.

The driver display screen is another source of annoyance. It’s pretty small and contains lots and lots of information, to the point where the typeface is too small to be read on the run by anybody who relies on reading glasses.

Power delivery in the MG7 is smooth and responsive, and it doesn’t take long to feel confident with the turbo-petrol engine. For a bit of extra fun, flick it into Sport mode and open the exhaust; gear changes become more pronounced, and the engine note gets noticeably throatier. It’s not a performance sedan, but it’s definitely engaging on the road.

Handling is another highlight. The steering is responsive and firms up depending on your selected drive mode, and the low-slung stance helps the car feel surprisingly nimble in corners. That said, it’s not always surefooted when accelerating out of tight bends, which reminds you that the MG7 is sporty but not track-focused.

Visibility is adequate but not perfect. The thicker pillars, lower roofline, and relatively small windows do make the cabin feel a touch enclosed, and there’s some road noise, which is enough to remind you it’s not a luxury saloon, but it never becomes intrusive.

The MG7 feels agile in tighter spaces, and the 360-degree camera system is high-quality. Parking is straightforward, which frazzled parents will appreciate.

The MG7 has a maximum five-star ANCAP safety rating from testing done in 2025 and scored well across its individual criteria with 88 per cent for its adult protection, 85 per cent for child protection, 80 per cent for vulnerable road user and 81 per cent for its safety assist.

Passive safety items include seven airbags including a front centre airbag and curtain airbags covering both rows. Families will like that there are two ISOFIX child seat mounts and three top-tether anchor points but realistically, two child seats will fit best. There are also powered locks for the rear windows and intelligent seatbelt reminders for all five seats. Parking is easy with the rear parking sensors and 360-degree view camera system.

Active safety includes forward and rear collision warning, lane keeping aids, lane departure warning and prevention, blind-spot detection, side exit assist and a relatively unobtrusive driver monitoring system.

Other highlights include emergency lane keeping, which will activate when there’s no response from the driver and the rear cross-traffic alert also gets assisted braking. The adaptive cruise control is fairly well-calibrated and it’s a bonus having the emergency call functionality, although it seems to connect to an MG service line, rather than directly with emergency services. And you have to select which country you’re in before it activates, which might not be a delay you want when you really need it!

There’s autonomous emergency braking with car, pedestrian and motorcyclist detection and it's operational from 4.0 – 85km/h and up to 150km/h for car detection but it is more typical to see that top figure closer to 180km/h.

Like other BYDs, the Sealion 5 comes with a six-year/150,000km warranty. Some of the competition have unlimited kilometre warranties, but to be honest, 150,000km in six years is going to be beyond the need and aspirations of most owners.

The EV battery is covered by an eight-year/160,000km warranty, and let’s not forget, BYD was a battery manufacturer before it started making whole cars. Certainly, the company is very bullish about the quality and safety of its 'Blade' battery technology, claiming it easily passes the technically-daunting 'nail-puncture' test.

BYD plans to have capped-price servicing for the Sealion 5, but no pricing announcements have been made yet.

Servicing also falls into line with other BYD models, so that means 12 months or 20,000km intervals.

MG backs the MG7 with a seven-year, unlimited-kilometre warranty. If you service exclusively through MG service centres, that coverage can be extended to 10 years or up to 250,000km, which makes it one of the more generous warranty offerings currently available.

At the time of this review, servicing intervals and service prices haven't been set for the MG7. It's fairly easy to secure servicing for an MG, as they have around 90 service centres nationwide at the moment.
