BYD Sealion 7 vs Hyundai Ioniq 6

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.

In the Ioniq 6 N Hyundai has built an incredibly quick and high-capable performance car. But that doesn’t mean it’s flawless and an obvious recommendation over its rivals.

Its looks remain divisive, and while obviously each individual will need to judge the design of the Ioniq 6 N themselves, objectively speaking there is a lot to like about this latest addition to Hyundai’s N stable. 

Yes, it’s very fast, but with all the N modes switched off it’s also a very quiet and relaxed sedan with a premium look and feel. So it will play the dual role of track terror and everyday family transport well. 

But it needs to be for the price, which is really testing the limits of Hyundai’s brand appeal. It obviously won’t be a best seller, but with the less-polarising Ioniq 5 N only selling approximately 300 cars since its launch, this could be a very niche proposition, reserved only for those who crave its special kind of electric performance.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

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 original Prophecy concept, which previewed the Ioniq 6, was a thing of beauty, a case study in elegance and simplicity. The final production version of the Ioniq 6 is a case study in awkwardness, with a design that polarised opinions.

For the Ioniq 6 N Hyundai has been given a second chance to try and make it look more appealing and less divisive. To that end they’ve added this gloss black bumper with an integrated splitter, highlighted by the N-specific fluro orange strip, as well as unique fenders and 20-inch forged alloy wheels.

The facelift also introduces much more appealing slimline headlights that help reduce the awkwardness.

At the rear, there’s a new rear bumper design, with more black to try and hide some of its most awkward lines, plus an unmissable rear wing to further attract your attention. And while it undoubtedly provides a sportier, more dynamic look, it actually provides up to 100kg of downforce.

Inside, Hyundai has made a number of key enhancements to ensure the Ioniq 6 N looks suitably sporty. There’s a sports steering wheel, complete with a pair of N buttons to immediately activate the more dynamic driving modes, plus sports seats and even a soft knee pad built into the side of the centre console, so you can brace yourself when you're lapping the track at speed.

There’s a 12.3-inch multimedia touchscreen in the centre, which houses all of the various car settings, including the very detailed N performance driving modes. This is where you can either program the N buttons or dial up the individual settings.

There’s also track-themed graphics that appear on the head-up display, if you really want to do your best Oscar Piastri impression.

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.

The cabin is very practical too, despite its sportiness. There’s good storage spaces, including a pair of cupholders and a tray built into the centre console.

There’s also USB-C charging ports in the front and back of the cabin to keep small electric devices charged, as well as a smartphone wireless charging pad.

By relocating the controls usually found on the door (windows, mirrors, unlock/lock buttons), the door pockets have been sculpted out to create more width and space for the front seat occupants.

It’s comfortable and roomy too, especially in the back, where Hyundai has taken advantage of the Ioniq 6’s bespoke electric underpinnings to have a flat floor with good knee and legroom.

The boot measures 371 litres, which is on the smaller size for a mid-size sedan, and well short of the class leaders, like the 524L Toyota Camry.

While it pushes the boundaries in terms of performance, it also stretches the appeal of Hyundai as a brand. Priced from $115,000 plus on-road costs,  it’s the same price as the Ioniq 5 N but that still makes it one of the most expensive Hyundai’s ever sold. Only the $119,750 Ioniq 9 is pricier.

For the asking price, beyond the performance elements, standard equipment includes LED headlights and tail-lights, 20-inch alloy wheels, dual-zone climate control, an eight-speaker Bose premium sound system, a 12.3-inch multimedia touchscreen, wireless Apple CarPlay and Android Auto and Hyundai’s Digital Key2.

There is only a single specification and the only option is the choice to delete the sunroof, free-of-charge (although, given carmakers typically charge extra for a sunroof, it seems a little sneaky to not get any discount for removing it).

However, if you want to make your Ioniq 6 N more special, there is also a carbon package available through the accessories department. It adds an even larger rear wing and unique front splitter and side sills (all in carbon fibre, of course) for an additional $27,000, pushing the price past $142,000 before on-road costs.

While it may be expensive for a Hyundai, in terms of how many dollars for how much performance, it’s arguably one of the better value performance cars on the market. Would be rivals include the $187,900 Mercedes-AMG C63, $156,990 Alfa Romeo Giulia Quadrifoglio and $169,100 BMW M3, although the latter will get a full electric vwersion in its next generation.

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.

As mentioned earlier, while it may be expensive for a Hyundai, if you want a car capable of making 478kW and 770Nm you’ll typically need to spend a lot more than $115,000. This makes the dual-motor electric powertrain the star of the show in many respects.

Those figures are the maximum performance available when you use 'N Grin Boost', a 10-second burst of ultimate power. The ‘normal’ performance is a still an incredibly impressive 448kW and 740Nm.

These come from a 166kW front motor and 282kW rear motor, to give you all-wheel-drive capabilities.

That’s enough for the Ioniq 6 N to do the 0-100km/h sprint in just 3.2 seconds with N Grin Boost activated (0.2 seconds faster than the Ioniq 5 N). Top speed is limited to 257km/h, which is obviously too much for the road, but Hyundai is pitching this as a track car and in that sense it will struggle to keep up with some supercars at the end of long straights, but that’s probably a minor quibble in the grand scheme of things.

Like most electric cars, the Ioniq 6 N has a single-speed transmission. But like the Ioniq 5 N, Hyundai has developed an artificial ‘manual’ gearbox, which it calls N e-shift. By torque limiting the engine to create a false ‘rev limit’ there are eight virtual gears for you to use via the paddles on the steering wheel.

But this is only part of the story, Hyundai has included a number of N-specific driving settings for the powertrain beyond N Grin Boost and N e-shift. N Torque Distribution has 11 different settings that allows you to adjust the torque split between the front and rear axles up to 95 per cent in one way or the other.

Then there’s N Drift Optimiser, which helps you do big skids, on the safety of a track, of course. Plus N Launch Control to shock your mates with V8s at the drag strip and N Track Manager to keep track of your lap times.

It all sounds very complicated but Hyundai has done a nice job of integrating the systems into the car and making the menu easy to navigate. And because these systems are largely digital, rather than mechanical, it actually helps make the car easier to drive in some regards.

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.

To power this track-focused EV, Hyundai has had to upgrade the 84kWh battery with specialised heating and cooling systems.

Range is rated to 487km, which is good without being great. And, unsurprisingly, if you access all the power available you will end up using the battery quicker, much like you’ll use more fuel if you drive an internal combustion engine hard.

For track use, Hyundai suggests a ‘20-20-20’ cycle of 20 minutes of track driving, 20 minutes of cooling and then 20 minutes of charging to ensure you get maximum out of a track day. Although we were able to do closer to 30 minutes of track driving from a single charge.

To make this possible, there is a special N Battery mode, which is able to maximise track usage by managing the cooling and output depending on the scenario. There are Drag, Sprint and Endurance settings, with Drag making the battery warmer for sudden acceleration, Endurance trying to keep it cooler to extend on-track range and Sprint automatically applying N Grin Shift when needed.

It’s an incredibly complex system but it speaks to the challenges of making an EV capable of the rigours of high-speed driving consistently.

In terms of charging, the key detail to know is, with the maximum charger, you can go from 10 to 80 per cent charge in as little as 18 minutes, according to Hyundai’s claim, and is compatible with either 400V or 800V charging infrastructure.

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.

To put it bluntly, the Ioniq 6 N is sickeningly fast. Literally, it can make you feel car sick from the passenger seat if the driver unleashes the power a little too frequently, which isn’t hard because the Ioniq 6 N offers near-instant torque.

The dual motors mean this swooping sedan launches out of corners with a ferocity usually reserved for supercars - it is that quick under hard acceleration. But pure acceleration is only part of the story when it comes to a proper performance car.

As impressive as the Ioniq 5 N is, it was always going to be handicapped by its taller SUV body, meaning the handling was somewhat dulled by its size and shape. The lower, more aerodynamic Ioniq 6 N is therefore noticeably more dynamic and responsive to drive.

The suspension and steering tune isn’t specifically tuned for Australian conditions, instead it’s based on the globally developed setup designed for the Ioniq 5 N, which Hyundai Australia did have input into.

Despite not being tuned specifically for Australia it still rides with impressive compliance for such a performance-orientated electric car. Even on the choppier back roads we tested it on, it feels controlled and compliant while still being responsive, without feeling uncompromising or uncomfortable.

But to really experience the true performance potential of the Ioniq 6 N, you need to hit the racetrack. Thankfully, Hyundai Australia allowed us to test it to its limits at Sydney Motorsport Park.

Free from speed limits the immense power can be unleashed and to make the experience even better you can use the N e-shift and the N Active Sound+ - three separate artificial soundtracks that are designed to mimic engine noise.

There is one that can broadly be described as ‘futuristic’ and another that is meant to sound ‘electric’ but neither are good enough to bother with. Instead, if you stick to the one that sounds like Hyundai’s petrol engine you’ll enjoy it.

While it is clearly an artificial sound, and there will be haters who just don’t like it (and they can leave it switched off), Hyundai has done a brilliant job mimicking the sounds of a proper petrol performance car. So much so that when you lift off the accelerator, you actually hear a ‘snap, crackle, pop’ from the rear of the car, as if there is an actual exhaust making the sound.

What the noise does do is really help you with a sense of speed, as does the N e-shift, not only helping you drive faster but also just making the experience more fun.

For the serious track-day drivers the amount of adjustability in the Ioniq 6 N is brilliant. In particular the N Torque Distribution system, which allows you to shift the drive split front-to-rear on the move. Experimenting with this system, there is a clear difference between the handling not only as you switch between modes, but if you’re really, really serious, you can even adjust it during your on-track run. As the tyres get hotter, shifting more drive rearwards helps the car rotate better and punch out of the corners easier.

However, while Hyundai may have designed it as a track-capable, ‘Corner Rascal’, as they like to say, the reality is, most of the time you’ll be driving, you won’t be on a racetrack.

Even so, N Road Sense is a special setting that is able to recognise a double curve road sign and urges the driver to activate N mode and have more fun, so it’s always looking to encourage you to have a good time.

But what about when you’re not driving fast? How does the Ioniq 6 N stack up as a daily drive? Well, one of the elements of  performance EVs that I personally appreciate, is how quiet and relaxed they are when you don’t need to go fast. Unlike an internal combustion performance engine, which can feel like a caged animal at suburban speeds, an EV with 448kW is as smooth and quiet as an EV with 148kW.

It means it plays both its roles - weekday commuter transport and weekend fun machine - with equal ability.

The Ioniq 6 N gets a comprehensive list of driver assistance systems, under the umbrella of Hyundai SmartSense.

Among the safety gear included is forward collision assistance, blind spot collision avoidance and the brand’s mild-autonomous functionality, 'Highway Drive Assist 2', which can both maintain speed and lane centring under certain conditions.

The car is also equipped with Hyundai Bluelink, the brand’s connected car service, which includes an ‘SOS’ function that can call the emergency services if you’re in an accident where the airbags deploy.

While there is no questioning the amount of technology Hyundai has put in the car, like so many other models in the range, the systems need more fine tuning to make them class-leading. There are still too many ‘beeps and bongs’ from the Ioniq 6 N, to the point of becoming distracting. While the lane keeping assist can be too uneven at times, needing more work to get it better calibrated for smoother driving.

The entire Ioniq 6 range has a five-star ANCAP safety rating, based on a 2023 test, and given there are no major structural changes (beyond some body stiffening), there is no reason to think the N model would be any worse.

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.

Hyundai covers the Ioniq 6 N with its usual seven year/unlimited kilometre warranty, with any non-competitive racetrack usage also covered. So you can do a track day, including the official N Australia organised ones, with peace of mind.

This applies even if you upgrade your tyres and brake pads in search of faster lap times, as long as you don’t enter into a competition, Hyundai will look after most mechanical on-track problems.

Service intervals are every two years or 30,000km, whichever comes first. Hyundai offers a ‘lifetime’ servicing plan that covers the first four years, but with only two services required - one for $645 and the second for $667.

As one of the best-selling brands in the country, Hyundai has an expansive nationwide dealership network, including extensive rural coverage and service centres trained to deal with EVs.
