Hyundai Kona vs BYD Sealion 5

What's the difference?

It’s easy to see why the Hyundai Kona leads the Aussie small SUV category, with this hybrid version enhancing the car’s abilities in key areas. Sharply priced and well-specified, comfortable and practical with a hugely efficient powertrain as well as refined dynamic performance. It’s a compelling package. 

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.

The Kona’s exterior mixes smooth curves across its softly rounded nose and swollen haunches with sharp lines and geometric shapes in the lower grille, wheel arches and rear bumper.

And when the current, second-generation version arrived in mid-2023 it swapped out its predecessor’s already slimline LED daytime running lights for an even thinner strip running the width of the car, in similar fashion to the Hyundai Sonata sedan and Staria people mover.

The single line light signature is repeated with the tail-lights, a brake, reversing and indicator cluster confined to the outer rear edges.

Throw in a conspicuous diagonal character line across the doors, and bright metallic accents making a visual connection between the top of the tailgate and the lower edge of the side glass and there’s a lot going on. 

Always a subjective call, but I don’t mind the Kona’s design, although our test car’s ‘Mirage Green’ paint finish leaves me (and my significant other) cold.

Inside, the colour palette is uniformly grey which contributes to a restrained, relatively low-key feel, although light trim for the headliner and pillar covers brightens the mood somewhat.

The dash treatment is cool and contemporary, comprising a wide wrap-around instrument and media screen panel next to a narrow tray on the passenger side.

Fit and finish is impressive and details like perforated centre panels on the leather-faced seats dial up the premium feel.

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.

Even though the Kona measures a relatively modest 4350mm end-to-end, it offers up copious amounts of interior space. Dr Who would be proud.

Lots of breathing room up front, with the ‘shift-by-wire’ auto transmission shifter’s location on the steering column freeing up extra space in the centre console.

There’s a lidded bin between the seats (the padded top of which doubles as a centre armrest) with an open tray the size of a shoebox in front of it (which includes a pair of swivel-out bottle or cupholders) as well as a wireless phone charging bay ahead of that.

Generous bins in the doors include a recess for large bottles, plus there’s a decent glove box on the passenger side and a handy open tray above it. Plenty of room to keep the bits and pieces of everyday life under control.

Power and connectivity for the driver and passenger runs to two USB-C sockets and a (180W) 12-volt outlet.

Switching to the back is where the Tardis factor steps up a notch, the Kona offering space more in line with a next-size-up medium SUV.

Sitting behind the driver’s seat set to my 183cm position there’s loads of leg and headroom and even enough shoulder room for three adults to get to know one another on shorter journeys. A close to flat floor also helps with foot room in the centre position. Worth noting the rear seat backrests recline slightly for extra comfort options.

No door bins as such but, again, there are recesses for bottles. Netted map pockets on the front seat backs are helpful as is a fold-down centre armrest, which includes a pair of cupholders.

Individual air vents for back-seaters (in the rear of the front centre console) is always a welcome inclusion, and there’s a small oddments tray underneath them. Another pair of USB-C sockets will keep devices charged.

Boot capacity is healthy at a class-competitive 407 litres (VDA), expanding to 1241L with the 60/40 split-folding second row seat folded.

There are storage wells behind the rear wheel tubs, multiple bag hooks and four tie-down anchors to help keep loads secure.

There’s a temporary space-saver spare under the boot floor, which gets a tick over the increasingly common repair kit option and you’ll be able to tow a 1.3-tonne braked trailer (600kg unbraked).

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.

The plug-in hybrid in question is the BYD Sealion 5. It has a claimed EV-only range of better than 100km, relatively quick charging, a decent sized battery, adequate performance, enough interior space for a family, good safety and lots of equipment. Oh, and it costs just $33,990, before on-road costs, in its entry-level Essential form. Incoming!

Equipment-wise, that sub-34K sticker gets you a 10.1-inch central info-screen, an 8.8-inch driver display, digital radio, a six-speaker stereo, wireless connectivity for Android Auto and Apple CarPlay and dual-zone climate control.

Throw another four grand on the table and you move up to the Premium version which adds plenty of kit for the $37,990 ask. That includes a panoramic sunroof, automatic tailgate, roof rails, heated and electrically folding mirrors, one-touch power windows, a six-way powered drivers seat and four-way powered co-pilot’s chair, a heated and ventilated driver’s seat and wireless charging.

The step up from Essential to Premium also includes a battery upgrade, and we’ll cover that off in the Under the Bonnet section below.

The Kona Hybrid is powered by a naturally aspirated 1.6-litre, four-cylinder petrol engine working in concert with a single electric motor, both driving the front wheels through a six-speed dual-clutch automatic transmission.

The all-alloy engine features dual variable valve timing and direct-injection to produce 77kW at 5700rpm and 144Nm at 4000rpm, the permanent magnet synchronous motor chipping in with 32kW/170Nm for a total combined outputs of 104kW/265Nm.

That power output is in the middle of the small hybrid SUV pack and torque is at the higher end. 

Kerb weight is a fraction over 1.5 tonnes and you can expect 0-100km/h acceleration in the high 10-second range with a top speed around 170km/h.

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.

Hyundai’s official fuel consumption figure for the Kona Hybrid Elite, on the combined (urban/extra-urban) cycle is a miserly 3.9L/100km, the 1.6L engine emitting 89g/km of CO2 in the process.

Minimum fuel requirement is 91 RON ‘standard’ unleaded and with a 38-litre tank theoretical range is around 975km.

On test, over several hundred kays taking in city, suburban and freeway running, we saw an average of around 4.4L/100km, which is impressive and a big contributor to the car’s appeal.

Using our real-world test number, the range figure comes in at a still handy 860-plus km.

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 first things that come to mind when it comes to driving the Kona Hybrid are comfort, quietness and lack of stress.

From an ergonomic point of view the dash and cabin layout make life easy. There are physical controls for key functions like heating and ventilation, as well as audio and drive modes. Not a fan of the hard driver’s door armrest, though.

The engine is quiet and the transition between combustion and electric power is seamless. It’s fun to watch the (available) graphic screen in the driver’s display illustrating where drive is coming from at any given moment. Without it you’d be hard-pressed to know.

Acceleration is more than adequate and the powertrain’s bias towards electric propulsion means take-offs are ultra-smooth. 

Suspension is by MacPherson-type struts at the front with a multi-link rear set-up and ride quality is outstanding. Despite the Kona Hybrid’s relatively large 18-inch rims, bumps and ruts don’t cause major disruption and the Kumho Ecsta PS71 tyres (215/55) are exceptionally quiet.

Steering accuracy and road feel are both good and drive mode switches between ‘Normal’, ‘Eco’ and ‘Sport’ are noticeable, the latter dialling up urgency and dynamic response.

That said, we found ourselves in Eco most of the time, without any penalty in terms of throttle response or cruising ability.

Torque vectoring helps keep everything buttoned down if you decide to press on through your favourite set of corners, the front seats remain comfy on longer drives while keeping you securely located and the ‘shift-by-wire’ electronic gearshift is slick.

Physical brakes are ventilated discs at the front with solid rotors at the rear and they operate with reassuring smoothness. An active hydraulic booster controls regenerative braking, adjustable through three levels. Warning: the most aggressive setting makes the car annoyingly ‘shunty’ at slower speeds.  

Driver-assist safety tech makes its presence felt occasionally, but never to a disturbing degree… with one exception.

Despite the ability to program a steering wheel button to short-cut directly to the appropriate screen, the need to cancel an incessant and sometimes inaccurate overspeed warning every time you start the car is a pain.

A tidy 10.6m turning circle helps in slow-speed manoeuvres as do front, side and rear parking distance warnings and a high-quality reversing camera.

The Kona Hybrid is as good or better than anything in the class when it comes to the drive experience.

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.

Passive safety in the Sealion 5 starts with no fewer than seven airbags including full-length side-curtain bags. 

There’s also a front-centre airbag, something we’d like to see in more cars, particularly at this price-point. Child restraint points in the rear seat are the ISOFIX type.

The BYD gets pretty much the full suite of driver aids, including autonomous emergency braking, blind-spot monitoring, rear-cross traffic alert with active assistance, stability control, active cruise-control, traffic-sign recognition, front and rear collision warning and tyre pressure monitoring.

The Sealion 5 also incorporates a driver-attention monitor which seems better calibrated than some earlier efforts from some of the Chinese carmakers. Also improved in calibration terms is the lane-keeping assistance which is still too violent for our tastes, but more subtle than some of the competition’s systems. But while the savagery of this system has been toned down, it appears to have been at the expense of sensitivity and, time and time again, the cameras missed road markings that were faded or dirty.

The major safety benefit in paying more for the Premium variant is the addition of front parking sensors and a 360-degree camera instead of the Essential’s simple reversing camera.

The Sealion 5 has not been ANCAP tested as yet, although BYD says this is largely down to ANCAP’s scheduling rather than any hesitance on BYD’s part.

The Kona is covered by Hyundai’s seven-year/unlimited-km warranty (upgraded from five years mid-last year), which is ahead of the mainstream five-year warranty pack.

Roadside assistance is complimentary for the first year, with the deal extended for another 12 months every time the car is serviced at an authorised Hyundai dealer. 

Speaking of which, scheduled servicing is recommended every 12 months/10,000km, which is a little lower than the (15,000km) norm for the category. After a complimentary check up at six weeks/1500km, the first seven services (in line with Hyundai’s ‘Lifetime Service Plan Pricing’) come in at $3782, for an average of $540 per workshop visit.

That’s on the high side considering an equivalent Toyota Corolla Cross (in line with ‘Toyota Service Advantage’ pricing) will set you back an average of $354 per service over the same period.

Hyundai has a network of 185 dealers covering every Australian capital, state and territory.

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.
