Hyundai Ioniq vs BYD Seal

What's the difference?

Just like the Kona EV, Hyundai's Ioniq is still one of the best EV options on the market today. It strikes an excellent balance by offering significantly more range and better energy consumption than the more affordable Nissan Leaf or MG ZS EV, while providing the familiarity of the Hyundai spec and drive experience at a price only a little higher than a top-spec Prius.

Its relatively high score is a product of these factors, but also the way in which its interactivity offers the early adopters the engagement they will be searching for.

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.

The Ioniq follows in the footsteps of eco hatches before it. You'll note this car's similarity in profile to the Toyota Prius, both shaped as such to secure low drag figures and therefore better economy and longer range.

While the Ioniq is a little more sedate than the wacky angles of the current Prius, there's no getting around the fact it's not exactly a cool shape. You could say it's interesting, perhaps, in the way it warps the low-drag box to Hyundai's styling cues, but dorky nonetheless. The LED headlights help lift it  a little, but the filled-in grille and small 16-inch wheels hardly lend this car extra street cred.

The Ioniq is more a proof of concept for early adopters who care a little less about the way the car looks and a little more about its drivetrain and technology, which is clearly the  focus here.

This can be seen in the Ioniq's interior, which has been re-worked for its most recent update. The digital features are impressive, with the floating 10.25-inch screen now totally dominating its dashboard.

I also like how the brand has given the instrument cluster a more modern design, with a cool floating bridge element over the top to eliminate glare, and, as always, Hyundai has made ergonomic use of its excellent switchgear and tidy steering wheel from the i30 and Kona ranges.

The climate unit has lost its tactile dials, replaced by touch-panel controls, and the lack of a transmission under the centre console has allowed plenty of negative space for the brand to play with, in this case a huge storage bay. There are also elements from more recently launched Hyundai models, which help to tidy the centre space up further, like an upright wireless-charging bay and shift-by-wire drive selector, which all looks very modern and neat.

It's a step towards things to come from the newly minted Ioniq sub-brand, which will do a lot more of this stripped-back, space-saving stuff with its next vehicle, the Ioniq 5 SUV. For now, though, the Ioniq is good as a half-step into the future. It's not as outlandish as a Tesla Model 3, for example, and will better suit a buyer looking for something a bit more familiar that still has a futuristic edge.

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.

As mentioned, there's actually quite a lot of space in the Ioniq cabin, and the design has been further stripped back with its most recent updates.

The front seat seems a bit high for a hatch, although ergonomically everything is correct for the driver, with a good amount of adjustability in the seat back and wheel.

The big, bright multimedia touchscreen is easy to use, and the single centrally mounted volume dial is welcome, but I do sorely miss the dials  for adjusting fan speed and temperature. Touch-panel controls, to me at least, are always inferior.

As already mentioned, the centre-console area under the climate unit has been almost entirely deleted for the electric variant, granting the driver a little more knee room, and leaving a deep rubberised bay for loose objects, maybe even small bags. This area also houses two 12v power outlets and one USB port. The centre console has been re-worked to include a smart, space-saving upright wireless-charging bay for your phone, the shift-by-wire console, and controls for the heated and ventilated seats. This area also hosts two large bottle holders, and a large centre-console box.

As is usual with Hyundai models, there's also a large bottle holder in the door, alongside a practical bin.

Rear passengers are treated to decent legroom, about on par with what you'd expect in a hatchback. Headroom is a little limited, both for getting in and out, with the descending roofline, so if you have family or friends taller than my 182cm height, they might be less than pleased.

The rear-seat area gets bottle holders in the doors and in the drop-down armrest, although there are no power outlets, just dual adjustable air vents.

The hatch body of the Ioniq makes for a decent boot volume of 357 litres, enough for a large pram or, in the case of my testing, the largest of the CarsGuide luggage cases, with ease. Hyundai gives you a little satchel to tidily store the standard powerpoint to Type 2 charging cable. A Type 2 to Type 2 cable, which you will need to charge at public outlets (up to 7.2kW) is not included.

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.

The Ioniq electric has a single motor on the front axle producing 100kW/295Nm. It's the least powerful EV in Hyundai's range, but still out-punches cars like the Toyota Prius on raw power. It drives the front wheels via a single reduction-gear transmission, and the Ioniq electric also has re-worked regenerative braking for its most recent update.

This is powered by a huge-for-its-size 38.3kWh lithium-ion battery pack under the floor.

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.

The huge 38.3kWh battery pack and official combined energy consumption of 15.7kWh/100km, grants the Ioniq electric an impressive 311km (WLTP) range. As already mentioned in the pricing section, this lets the Hyundai electric hatch strike a good balance for urban commuters, however, under our mostly urban testing, it's an even better story.

For context, electric cars are far more efficient when operating in an urban scenario than they are on the open road. This is because they can regenerate energy more often and are less susceptible to losses from drag. The Ioniq has a superb regenerative-braking system, which can be completely customised to the user's preference. Want to drive it with no regen braking (like a normal car)? You can. Want to have the full eco experience, and have the car's motor bring it to a halt even without using the brake pedal, thereby maximising the amount of energy recouped? You can absolutely do that, too.

For most of my week, I stuck the Ioniq in its maximum regenerative setting and was very impressed to find it return an efficiency rating of 12.3kWh/100km. Not only is this number well below its claim, it's by far the most efficient electric car I have driven, and the only one I haven't tried yet is the brand-new MG ZS EV.

Colour me very impressed. The Ioniq charges via the most popular socket, the European Mennekes Type 2 combo. On DC, the Ioniq can charge as fast as 100kW allowing for a charge time of 54 minutes from empty to 80 per cent. On AC, its max charge input is a frustratingly low 7.2kW, making for a charge time of six hours and five minutes (more expensive rivals will charge at 11kW or even the max 22kW),  while from a 240v wall outlet (~2.3kW) it will charge in 17 hours and 30 minutes.

My single charge session was at a council-supported clean-energy Tritium charger with a max output on DC of 112kW. It charged my Ioniq from about 35 to 80 per cent in 32 minutes, and cost around $7.

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 Ioniq's familiar Hyundai switchgear makes it largely feel like the brand's i30 from behind the wheel, and this is a very good thing. This car is immediately ergonomic and user friendly, although the seating position is a little high, preventing it from feeling particularly sporty.

The Ioniq emits a pleasant choral tone at low speeds, which enhances the perception you're steering something from the near future. It also helps alert pedestrians nearby, which was one of my pet peeves about the silent Tesla Model 3. The noise is interesting enough that you'll have people peering closely at it to figure out what's going on. It even gets louder as you accelerate, as though the motor is making it and it's not entirely artificial. Cool.

This EV is silky smooth to drive and accelerate. Like other Hyundai electric cars, it doesn't have the unleashed electric torque of a Tesla, but it feels  well attuned to driving around in an urban scenario, with viscous acceleration and regenerative braking. I was surprised to discover how heavy it feels, though.

I was expecting it to be heavier than its hybrid or PHEV counterparts but compared to the hybrid Prius I drove only a week or two prior, the electric Ioniq feels obese.

Upon closer examination, the Ioniq electric weighs 200kg more than the Prius, at 1575kg. It doesn't sound outrageous but it's enough to have this little car's suspension wallowing and occasionally crashing over bumps that wouldn't bother its hybrid versions or, indeed, the Prius.

This is perhaps emblematic of the issues facing smaller EVs like this. To get more than 300 kilometres of range, they need a lot of heavy batteries. Manufacturers can better hide this with the existing heft and better suspension travel of SUVs. The Kona EV, for example, feels less hefty than this little hatch.

Regardless, the electric motor dispatches with the Ioniq's weight easily when you really want to accelerate, and while it doesn't provide the hold-on-for-dear-life acceleration of Teslas, it's more than enough for a daily commuter. Unlike the Prius, the Ioniq does genuinely feel pretty sporty in the corners, thanks to steering that's on the heavier side, and a firm, responsive damper tune.

The regenerative braking is particularly good on the Ioniq. Using paddle-shifters usually reserved for changing gears, the Ioniq instead lets you  alter the amount of regenerative braking available. Feel like coasting a bit faster? Flick the Regen braking off. Feel like maximising economy and range? Max it out in the drive mode of your choosing, and you can use it as essentially a ‘single pedal' car (you can go or stop by using the throttle alone).

It even has an auto mode, which I found to be pretty intuitive. Paired with a few different display options to let you get superior feedback on how you're tracking with battery usage, it's brilliant, and more electric vehicles should take note.

So, this is an eco-focused electric car that is reasonably engaging to drive if a little heavy. Most importantly for the electric era, it's highly interactive, helping you really understand how your inputs are affecting its battery usage, and how you can better drive it to maximise range.

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.

Hyundais are all covered by a competitive five-year and unlimited-kilometre warranty, which includes 12 months of roadside assist. The roadside assist is topped up for an additional 12 months with every genuine service, and the battery pack in EV models like the Ioniq is covered for eight years or 160,000km.

Hyundai's service pricing is amongst the best in the business, and with less moving parts, the electric Ioniq is the cheapest in the range with the first five services for the life of the warranty fixed at just $160 per 12 monthly or 15,000km interval.

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.
