BYD Sealion 7 vs Hyundai Ioniq

What's the difference?

The BYD Sealion 7 Performance is well-priced and well-equipped. It more than holds its own against its mid-size electric SUV rivals. It has great motor outputs and it handles comfortably on the road. There's a lot to like here but some of the technology needs to be tweaked.

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.

It may be named after a sea lion but it doesn’t resemble the blubbery cuteness of the creature itself. However, its sleek dynamic styling and performance outputs do call forth some of the creature's water prowess. 

This prowess is hinted at by the 20-inch alloys which are fitted with Michelin tyres and red brake calipers. There’s some Porsche-like design notes in the wide swoopy nose and LED headlights. The rear is also quite handsome with its long LED band strip and narrow window giving it a sporty silhouette.

Head inside and the Performance showcases the best BYD cabin I've sampled. There are no strange accents or panelling like there are in the Atto 3. This proves that BYD can do premium well.

The quilted leather upholstery feels supple underhand and the sports seats with integrated headrests reminds you what it can achieve in a sprint.

The swoopy design is carried over inside with the door panels. The dashboard is simply styled but headlined by an enormous 15.6-inch display that can rotate between landscape or portrait mode. Some may liken it to an iPad but it works.

The panoramic sunroof keeps things bright and cheerful but there are some simplistic elements that are hard to ignore. Like the lack of buttons, minimalist mirror cover design on the sunvisors and a rather plain-looking centre console.

Everything else flows and my favourite feature inside is surprisingly the lever door handles! They're functional but cute.

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 cabin has space, space and then more space. Passenger comfort is all but guaranteed with the available leg- and headroom in each row.

The functions for the electric front seats means it's easy to find a comfortable position. Door apertures are wide for each row and despite a relatively low 140mm ground clearance, it's still an easy SUV to slide in and out of.

Technology looks great and the large 15.6-inch multimedia display is what catches your eye first. Graphics are sharply rendered and the touchscreen responsive. There's a lot of information and menus embedded into the display which means it's a system that will take you a beat to get used to.

It's not unique but the in-built voice assistant rarely works as it should and needs some work. Also, because of the lack of buttons and dials, all functions are accessed via the screen. I don't like this because it tends to draw your eyes from the road far more often than it should and some functions - like the heat and ventilation for the front seats - are buried in a few menus.

There is wireless Apple CarPlay and Android Auto but there are some gremlins that need to be ironed out. The connectivity is easy enough but the steering wheel mounted phone control didn't access Apple CarPlay. So, I couldn't hang up my phone call properly, it would instead access the Bluetooth phone menu and dial my last call. I had a few 'butt' dials this week because of it.

Storage is on par with the Performance rivals and up front the burden falls across the large glovebox and middle console but there is also a shelf underneath the centre console for bigger items, like a handbag. There are two phone cradles, although only one offers wireless charging, and two height-adjustable cupholders two drink bottle holders and small storage bins.

In the rear, you get two device pockets and a map pocket on the back of each front seat. There is a fold-down armrest with retractable cupholders and a small storage pocket (think Kindle-size) and there are storage bins in each door.

The boot capacity is a decent 500L and the floor can be adjusted to two heights, one offering a level loading space. There is also a frunk storage of 58L for any cables or random bits you don't use often. Under the boot floor there is also enough room for cables and the tyre repair kit. The powered tailgate can be access via your keyfob as well.

For a flagship grade, I would have expected a few extra amenities in the rear, like climate control and sunshades but it does have directional air vents, reading lights and a USB-A and C port.

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.

On the one hand, forking out over $50k for a car which looks like this is a tall order. On the other hand, there is no other electric car that really falls into this price bracket, and when you think about it, it's only a few thousand dollars more than a top-spec Prius.

The aggro never-EV types will argue you can have a very good hot hatch, like say, Hyundai's own i30 N for less, but then this car really is for those early adopters who are after a slice of future drivetrain tech rather than a complete value offering.

In the context of the EVs currently available in our market, the Ioniq shines. Yes, it is more expensive than rivals like the Nissan Leaf or MG ZS EV, but it also offers more range than either of those, at 311km measured to the more accurate WLTP standard.

This is short of Tesla's Model 3 standard range, but also more than $10k more affordable, and as I discovered on my week of testing; 311km, and it really is 311km, is plenty for a predominantly urban commuter to get by with either routine maintenance charging, or a once-a-week stop at a DC charger.

So, value then? As this car has probably the minimum electric range you really want for an Australian city at a price only a little above rivals which fall short, it's in quite the sweet spot.

Oh, you probably want to know about equipment, too. Our Ioniq electric Premium scores familiar equipment from the facelifted Hyundai i30 range, including a 10.25-inch multimedia touchscreen with Apple CarPlay and Android Auto connectivity, built-in sat-nav integrated with charging-station distances, a 7.0-inch digital dash cluster, eight-speaker premium audio system, 16-inch alloy wheels, LED headlights and DRLs, single-zone climate control, leather-appointed interior trim with heated and cooled front seats, a heated steering wheel, auto-dimming rear vision mirror, wireless phone charger, opening sunroof, and keyless entry with push-start ignition.

It's a good array of items, and we'll touch on this car's fully equipped safety suite later. The only notable omissions for now are the lack of a holographic head-up display and the lack of dual-zone climate control.

The Performance is all-wheel drive and is fully electric with dual motors, a squirrel cage induction motor located at the front and a permanent magnet synchronous motor at the rear. Together they produce up to 390kW of power and 690Nm of torque.

This gives the flagship grade a 0-100km/h sprint time of just 4.5 seconds. There’s obviously ample power to be had here which will delight EV fans who like that tummy-falling sensation when accelerating.

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.

The Sealion 7 Performance has a blade battery with a large 82.56kWh capacity which supports a 456km WLTP driving range. This isn’t terrible for city drivers but a regional driver will likely want a longer range. BYD includes a portable charging cable with the model.

Charging is sorted via a Type 2 CCS charging port which accepts up to 11kW on an AC charger and up to 150kW on a DC charger. On a 150kW DC charger, you can go from 10 to 80 per cent in as little as 32 minutes and that increases to more than eight hours on an 11kW AC charger. All of the figures are quite good and help with the general day-to-day convenience.

The official energy consumption figure is 20.4 kWh per 100km but after doing a healthy mix of open-road driving and city stuff, my average has popped out at 19.1kWh. I reckon it's a solid result for a ‘performance’ grade but I didn’t find the regenerative braking to be particularly strong on this model.

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.

The Performance grade offers plenty of power that is delivered wickedly quick without feeling overwhelming when you have to accelerate. You still feel in control, which is very important when you have outputs like this does.

The steering is responsive and light enough for quick lane changes. The general on-road handling is quite refined but there is more roll in corners than you’d expect and this is the only time the power can make the handling feel a tad wobbly.

Surprisingly, there isn't a one-pedal function and the regen braking isn’t particularly strong. It’s difficult to ‘creep’ forward in this in stop/start traffic where it can feel a bit jerky at times, so it handles best on the open road.

Visibility is mostly good but the rear window is narrow and a digital rear-view mirror would have been welcomed in this model. Suspension is sports-firm but forgiving over bigger bumps. 

The 360-degree view camera and surrounding sensors makes this super easy to park and honestly, you shouldn’t have any trouble manoeuvring the Sealion 7.

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.

The Ioniq electric comes with the full suite of Hyundai SmartSense safety features, with active items including freeway-speed auto emergency braking (detects vehicles up to 180km/h, detects pedestrians up to 70km/h), lane-keep assist with lane-departure warning, blind-spot monitoring with rear cross traffic alert, adaptive cruise control, driver-attention alert, and auto high-beam assist.

This is backed by the usual stability, brake, and traction systems, as well as seven airbags (the standard dual front, side, and head array, plus a driver's knee) securing the Ioniq a maximum five star ANCAP safety rating dating back to its launch in 2018. It scored highly across all categories.

The Sealion 7 is covered by a six-year/150,000km warranty which is good for the class. The battery is covered by an eight-year/160,000km warranty which is a normal term.

The Sealion 7 gets a 10-year capped price servicing but it’s expensive compared to some of its peers at $4157.

Servicing intervals are spaced at every 12 months or 20,000km, whichever occurs first.

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.
