BYD Sealion 5 vs MG HS

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.

There are a few niggles with the latest MG HS, for example the annoying driver-attention monitoring and expensive maintenance costs. We’ve not had a full sample of its open-road performance yet either, which may prove more telling.

Yet the HS is shaping up to be one of the most successful product updates of recent years, second only to, I don’t know, the MG3? The family SUV is also backed by a 10-year warranty and, despite the drastic improvements, doesn’t cost a whole lot more than before.

The entry-level Vibe is our pick, there's no need to spend more. It features all manner of safety equipment and a quiet drive but with cloth upholstery that doesn't get all sticky and sweaty in the Australian climate.

The end of 2024 is the tipping point where MG goes from cheap and cheerful to a real headache for established players. Perhaps not for the strongest in the segment like the RAV4 and Nissan X-Trail, but the HS is now an easy car to recommend for a family looking for a spacious SUV that drives their dollar further. The hybrid will boost appeal further when it arrives next year.

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.

Though the previous HS had shapely bodywork, the wheels sat too far in-board and the rear end looked awkward. It’s not the same story with the new model which is designed as a family SUV first, rather than a converted hatchback platform.

Part of the improved looks are better proportions. The new HS is 81mm longer, 14mm wider and rides on a 45mm longer wheelbase yet sits 21mm lower for a sleeker appearance.

The front end takes cues from the new MG3 and ZS design language with a broad grille and thin LED headlights. At the back, MG’s design team references the UK’s capital with ‘Shard’ lighting signatures that also appear in the alloy wheels.

It is still fairly anonymous, though perhaps that comes from a lack of familiarity with the brand. The painted wheel arch cladding and metallic-only paint give it a premium boost.

The biggest improvement is inside, where the HS takes plenty of inspiration from the excellent MG4 electric car with the hexagonal steering wheel (though here with perforated leather finishing), high-set controls and confident lines. It’s a welcome, modern change after the old car’s bloated cabin design.

There are soft-touch rubbery materials in all sorts of prominent places, including on the dash top, front and rear door cards as well as where the driver’s knees rest on the doors and transmission tunnel.

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.

There is nothing especially ground-breaking about the MG HS’s front cabin. The cupholders are medium-sized and the door bins have enough storage for a one-litre bottle, so this is no Skoda Karoq when it comes to clever cabin solutions.

Telling a tale of the HS’s Roewe RX5 base car’s earlier 2022 launch (and the staggering development speed of personal technology) the lack of USB-C charging ports is now frustrating with all USB ports regular old-school items. Apple CarPlay or Android Auto phone mirroring requires a cabled connection.

The centre multimedia screen is high resolution with day selectable light and dark modes. It was a little laggy to use MG’s software, however, especially when swiping across menu screens. 

There are four hard shortcut buttons beneath it that can jump to the home screen, activate the HS’s front and rear demister and turn the ventilation on and off.

To adjust the temperature you need to go into the touchscreen, though there is a persistent shortcut on the main menu.

A 12.3-inch digital cluster has several selectable info displays and can show navigation mapping and directions in Excite and Essence trims. 

The seats are comfortable and supportive and it's easy to find a good driving position thanks to power-adjust driver's seat and tilting/telescoping wheel adjustment. The front passenger does not get height adjust, though, and is set too high.

Where the extra size pays dividends is in the back seat which has ample room for passengers beyond 185cm, especially when it comes to leg space. The fold-out armrest is sturdy, too, with twin cupholders. Rear air vents are fitted to only the top-spec Essence.

For baby capsules or child seats the HS has ISOFIX anchors fitted to all three rear seats matched with a trio of top tether points.

The MG HS’s boot is about average for the class measuring 507 litres. It grows to 1484L with the 60:40 backrest folded. For reference, class leaders include the Toyota RAV4 (580L), Nissan X-Trail (585L) and Volkswagen Tiguan (up to 615L with rear seats slid forward). 

There are few amenities, with no 12-volt socket, only one (dim) boot light and no shopping bag hooks. The carpet isn’t bargain basement and the luggage cover is sturdy with additional separated storage compartments below the floor and netted cubbies off to the side. 

MG has also been smart in packaging a space saver spare tyre beneath the boot floor (and a cumbersome Styrofoam piece).

Shock horror, the new HS is 10 per cent more expensive than before… but that still makes it $33,990, drive-away, for the basic Vibe — easily undercutting established rivals from Honda, Mazda, Toyota and others. 

You get a lot for that extra $4000, too, right down to basic presentation. There’s no fridge-like solid white paint with all six hues either metallic or pearlescent for no extra cost. MG even offers the upper trims with the option of an eye-catching tan upholstery colour. 

The three-strong trim line-up starts with the Vibe: dusk-sensing LED headlights, 18-inch alloy wheels, adaptive cruise control, auto wipers, tyre pressure monitoring, a six-speaker sound system, nice cloth upholstery and six-way power adjust driver’s seat are standard.

The Excite sprinkles in 19-inch alloy wheels, perforated synthetic leather upholstery, navigation, fog lights and MG’s 'iSmart' connectivity system for a smart $36,990, drive-away.

The range-topping Essence gains a panoramic sunroof, rear privacy class, a power tailgate, front parking sensors, wireless phone charging, eight-speaker audio, 10-way power adjustable driver’s seat with memory, seat heating, dual-zone climate control, rear air vents and wireless phone charging for $40,990, on-the road. 

The short of it is that, although MG’s prices are up, even the basic Vibe is a more enticing proposition on price than the new Chery Tiggo 7 Pro Urban ($39,990, drive-away) and established Mazda CX-5 Maxx (currently on offer for $37,990, drive-away).

It also is much closer to the popular GWM Haval H6 ($31,990-$37,990, drive-away) — if only MG had brought ventilated seats to the flagship Essence then this mid-sizer would be (almost) sold on paper alone.

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 new HS petrol has a 1.5-litre, turbo-petrol, four-cylinder engine that develops 125kW at 5000rpm and 275Nm from 3000-4000rpm, with those outputs up 6.0kW and 25Nm on the old car.

MG claims new engine features, including the variable geometry turbocharger, centre-mount variable valve timing and a lighter dual-mass flywheel, add up to a 30 per cent improvement in engine response.

More importantly, the insulation is excellent. You barely hear any unpleasant engine noises out on the road and although the four cylinder’s tone isn’t sexy at full-throttle, it is warm and pleasant enough.

The HS petrol is front-wheel drive only which may rule it out for some buyers, but there is a saving grace. The new seven-speed type dual-clutch transmission behaved itself impeccably on a brief first encounter taking in awkward hill starts and reverse manoeuvres. It’s a huge improvement over prior efforts and more refined than even a Hyundai or Kia dual-clutch.

MG claims a 0-100km/h acceleration time of 9.6 seconds, which is about right for entry-level versions of the HS’s typical rivals.

MG no longer offers a more powerful 2.0-litre turbo but a plug-in hybrid with a punchy 223kW and an all-new full-hybrid option will join the line-up in the first quarter of 2025, details of which are yet to be confirmed.

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.

In the ADR combined (urban-extra urban) fuel efficiency cycle, the MG HS petrol is rated at 6.9L/100km, emitting 156 grams of CO2 per kilometre in the process. A 55-litre fuel tank gives the HS a theoretical driving range of around 800km.

We weren’t able to get a true read on the fuel consumption but the trip computer showed 8.1L/100km after an hour-long run. It lacks an idle start-stop system and requires 95 RON premium unleaded petrol.

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.

MG’s launch drive program was too brief to really get under the skin of the HS, which is a shame because the initial signs are extremely positive.

Compared to the old ZS, in which a gumnut hitting the roof was loud enough to distract you from your thoughts, the new car is packed with sound deadening for a vastly more premium experience.

The electronic power steering system has a natural ratio (2.6 turns lock-to-lock) and weighting in 'Comfort' and 'Sport' modes, which cannot be said for rivals such as the Chery Tiggo 7 and Haval H6.

This new HS rides nicely, too, with enough compliance from the suspension without sacrificing body control — at least around town. It has struts up from with a multi-link rear end which is not a given, even in this segment.

There were a few sharp-edged bumps that sent a shock through the body but that is to be expected on Sydney's awful roads. The new HS rides about as well as a Mazda CX-5 and believe us, that is a dramatic improvement.

Visibility out the front and sides are good as is the comfortable driving position, however I wasn’t able to move the driver’s side mirror far enough out for my liking. That’s a small blip in an otherwise strong first showing.

The MG HS has not yet been evaluated by an independent safety testing body such as ANCAP or Euro NCAP.

MG has fitted the new HS with seven airbags, including driver and passenger, front side, side curtain and a centre airbag.

The HS has a long list of active safety and driver assistance features, such as front and rear auto emergency braking with junction detection, lane-keep assist, blind-spot monitoring, adaptive cruise control with stop and go and driver-attention monitoring.

I can’t say all the aids are perfect but the adaptive cruise control and lane-keep assist systems were less intrusive than those in Chery and Haval products.

The regularly-beeping driver-attention monitoring remains a constant frustration as it does across almost every brand at the moment.

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 has recently moved to a 10-year/250,000km new car warranty in Australia which covers the HS and is the longest non-conditional offer in the market.

GWM/Haval, Kia and SsangYong remain at seven years while Mitsubishi requires you to service the car at a main dealer for its 10-year guarantee.

This long warranty period should help allay concerns for new MG buyers that the brand stands behind its products.

Less impressive is the cost of maintenance, which adds up to $2354 over five years/75,000km with a particularly steep $936 service at the four-year mark. There’s a big $1647 service at 120,000km, too.
