BYD Seal vs Hyundai Ioniq 6

What's the difference?

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 Hyundai Ioniq 6 will stand out in any automotive crowd, thanks to its distinctive aero-influenced design.

It’s well-equipped for the money, surprisingly roomy, energy efficient and notwithstanding some niggles around the ride and steering feel, comes up to scratch dynamically.

Does it do enough to apply the thumb screws to the likes of Tesla's Model 3? I think it’s got a pretty good shot, and it will be interesting to see if EV buyers embrace the car’s unusual streamlined look.

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

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.

Lots of cars are said to be “shaped by the wind” but all you have to do is look at the Ioniq 6 to know that in this case it’s 100 per cent true.

In fact, images of the car in Hyundai’s wind tunnel show it performing more like a perfectly shaped wing than a four door sedan.

With a drag co-efficient (Cd) of 0.21 it’s slicker than the ultra low-drag Tesla Model 3 and Porsche Taycan. And while not conventionally pretty it’s certainly a striking and unusual design.

Flush door handles? Of course. Carefully sculpted spoilers front and rear? Yep. Active air flaps? Check. The RWD Dynamiq’s 18-inch alloy rims are shaped for aero efficiency, while the top-spec Epiq grade even swaps out conventional side mirrors for super-cool digital cameras and interior OLED screens.

And the sleek looks continue inside with a two-section dash divided horizontally by a swoopy winged insert and topped with a pair of 12.3-inch screens covering multimedia and instrumentation.

The look and feel is minimalist. A lot of the controls are on screen or digital, but a physical dial for audio volume gets a big safety and convenience tick. 

No gearshift in the bridge-like centre console. A rotary stalk is located behind the steering wheel on the right-hand side.

There’s configurable ambient mood lighting with six pre-selected themes and the materials used inside are suitably eco-friendly.

Cloth seat trim is recycled PET plastic, as is the headliner, the dashboard skin is manufactured using bio-ethanol, the carpet is made from recycled fishing nets (!), and bio paint (partially derived from vegetable oils) is used on the doors. 

Yes, there’s leather, but its dyeing process uses biodegradable flaxseed oil rather than conventional pigments, which is a good thing in terms of fewer harmful microorganisms in waste water, and is claimed to reduce CO2 emissions by 3.8kg per car. 

On the outside, recycled pigment paint made using ‘end-of-life’ tyres is applied to the body cladding, and bamboo charcoal pigment paint is used in the ‘Digital Green’ pearl colour option.

Speaking of which, there are seven other colours available; three more pearl shades - ‘Abyss Black’, ‘Ultimate Red’ and ‘Biophilic Ink’, as well a single metallic ‘Nocturn Gray’ and a solid ‘Byte Blue’. ‘Gravity Gold’ matt finish is the only extra-cost choice at $1000. 

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.

The Ioniq 6 is just under 4.9m long and the wheelbase is close to three metres, so no surprise there’s an impressive amount of space inside the car.

A flat floor enhances the roomy feel, plus controls for windows and mirrors are located in the centre console or on the dash rather than the front doors, which has allowed the armrests to be trimmed down for some extra breathing space.

As mentioned earlier, there’s no gearshift in the centre console, either. It takes the form of a rotary stalk on the right hand side of the steering column. It doesn’t take long to get used to and I found it pretty handy to use.

There are large bins in the doors with space for bottles, two cupholders in the console and a medium-sized lidded storage box (which doubles as a centre armrest) between the seats.

A lengthy tray underneath the main console keeps additional loose items under control and a generous glove box slides out from the dash rather than flipping open. So, there’s plenty of storage on offer.  

Move to the rear and it feels like you’ve teleported into the back of a stretch limo. With the driver’s seat set to my 183cm position there is huge legroom.

Hyundai says thanks to the use of high strength steel the backs of the front ‘relaxation’ seats fitted to the AWD models are appreciably thinner than normal, also increasing rear space.

Rear headroom is fine sitting in a normal, relaxed position, although sitting bolt upright my bonse grazes the headliner. 

Three abreast for adults will be okay for short runs, but not a goer for lengthy road trips. Three up to teenage kids will be fine, though.

Speaking of kids, parents will appreciate ‘Quiet Mode’ which limits audio to ‘25’ in front and mutes the rear. Perfect for uninterrupted sleep back there, or keeping the noise to a minimum for those furiously focused on their favourite game or a movie.

Backseaters are provided with bins in the doors, although the section scooped out for bottles is small, there are two cupholders in the fold-down centre armrest, netted map pockets on the front seat backs and a small slot for keys or a phone under the adjustable air vents at the rear of the front console.

Connectivity and power options run to three USB sockets in the front (one Type-A for media and charging, plus two Type-C for power only), a 12-volt socket under the front console, and two Type-C ports in the back. That’s plenty. 

Boot space is 410 litres (VDA), and the rear backrest split-folds 60/40 to liberate more room. Worth noting there are no tie-down anchors in the boot, but there is an underfloor storage compartment, plus a 45L ‘frunk’ under the bonnet of the RWD and a 14.5L storage space in the front of AWD models.

The boot lid is powered but there’s no spare, just a mobility kit. Grrrr!

If you want to hook up the tinny or camper trailer, towing capacity is 1500kg for a braked trailer and 750kg unbraked.

A bi-directional ‘Integrated Charging Control Unit’ (ICCU) allows for ‘Vehicle to Load’ (V2L) functionality on the inside and the outside of the car. There’s a house power-style three-pin outlet at the base of the rear seats or a simple adapter plugs into the charging outlet. Super-handy for camping, picnics, you name it.

Hyundai is offering the Ioniq 6 in three grades, the RWD Dynamiq at $74,000, before on-road costs, then the AWD Techniq at $83,500 and top-spec Epiq at $88,000.

At those prices you’re going to want a substantial list of included features, and aside from the performance and safety tech we’ll get to shortly, the standard equipment list is long.

The entry-grade Dynamiq features remote start, capacitive touch front door handles, dual-zone climate control, twin 12.3-inch screens covering multimedia and instrumentation, sat nav, a head-up display, Bose eight-speaker audio (with digital radio), Android Auto and Apple CarPlay, leather-appointed seats, leather-appointed steering wheel, alloy pedal covers, 10-way power-adjustable and heated front seats, LED headlights and tail-lights, auto rain-sensing wipers, a power (hands-free) boot lid and 18-inch alloy wheels.

Hyundai’s Bluelink connected car services are on board as is over-the-air software update capability. 

The Techniq adds a glass sunroof, 20-inch alloys shod with Pirelli P Zero rubber, ventilated front ‘relaxation’ seats, a heated steering wheel and heated rear seats.

Then the Epiq tips in digital side mirrors, a battery conditioning system, and high-efficiency (heat pump) heating.

Tesla’s three-grade Model 3 line-up is similar with a RWD entry model. It’s well specified and roughly $10K cheaper, but can’t match the Dynamiq’s driving range. The two more premium Model 3 variants are AWD and close on price to their Ioniq 6 equivalents.

Like the Ioniq 5 this car will be sold via a ‘direct to consumer’ online model, with dealer “delivery partners” charged with getting it into peoples’ hands.

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 entry-grade Ioniq 6 is the rear-wheel drive Dynamiq, featuring a 168kW/350Nm permanent magnet synchronous electric motor on the rear axle powered by a liquid cooled lithium-ion battery.

The all-wheel drive Techniq and Epiq models feature an additional permanent magnet motor at the front for a combined output of 239kW and 605Nm.

Drive is fed to the wheels via a single-speed reduction gear auto transmission on the rear or both axles.

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.

All versions of the Ioniq 6 carry the same 77.4kWh lithium-ion Polymer battery and the car’s 800V architecture allows it to use 350kW DC fast charging for a 10-80 per cent fill in 18 min.

The number of genuinely fast chargers available is increasing rapidly and that fill time is impressive.

Drop to 400V (50kW charging) and that time increases to 73 min, while 7.0kW AC charging from 10 to 100 per cent will take close to 12 hours.

The ports behind the not-fuel flap are a Type 2 for AC and CCS Combo2 for higher powered DC charging.

And if all else fails, you’re also equipped with a portable charger/cable so you can access house power for a full charge in, wait for it… 34 hours 20 min.

Quoted WLTP range for the RWD Dynamiq is 614km, that number dropping to 519km for the more powerful, dual-motor Techniq and Epiq models.

The WLTP combined cycle energy consumption figure for the Dynamiq is 14.3kWh/100km, with the Techniq and Epiq models at 16.9kWh/100km.

A ‘Disconnector Actuator System’ (DAS) on the front axle of the AWD grades is able to automatically engage and disengage drive to the front wheels as required, to reduce mechanical drag, lower energy consumption and increase driving range.

On test, in the Dynamiq, over a mix of suburban, b-road and freeway running we saw an average of 16.1kWh/100km which is a pretty good result.

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.

Hyundai claims the RWD Ioniq 6 Dynamiq will accelerate from 0-100km/h in 7.4 seconds, which is not hanging around, and it feels every bit that quick. 

In fact, it has more than enough performance for sharp response in the city and easy cruising on the highway.

Step up to the AWD Techniq or Epiq and you’re hitting 100km/h in just 5.1 seconds, which is properly rapid. 

A single-speed ‘shift-by-wire’ reduction gear auto transmission sits on the rear or both axles and you have the choice of ‘Normal’, ‘Eco’, ‘Sport’ and ‘Custom’ drive modes, which fine-tune power output, accelerator response, steering weight as well as power distribution between the axles on AWD models.

Hyundai’s ‘E-Active Sound Design’ (e-ASD) changes the ‘sound texture’ as you drive with a noise roughly approximating Luke Skywalker’s Landspeeder coming through the speakers.

It’s fun for a while, but I found myself turning it down, then off, for the majority of the launch drive. And in that silent mode you can feel and hear (or not?) the impact of the car’s super-slippery shape. No wind noise and only modest tyre rumble at 110km/h on the freeway. 

The Ioniq 6 sits on Hyundai’s ‘Electric Global Modular Platform’ (E-GMP) which features the flat battery pack mounted low down, skateboard-style, between the axles. 

Suspension is strut front, five-link rear, and although the set-up hasn’t been tuned locally, Hyundai Australia says it’s been involved in the development. 

The front seat remained comfy after hours behind the wheel, but it must be said bumps and thumps from typical highway surfaces made their presence felt on a regular basis.

That’s not unusual for a full electric vehicle, but with the RWD Dynamiq riding on relatively cushy Hankook 225/55 ventus S1 evo3 rubber, it’s surprising.  

In corners you can feel the effect of the car’s low centre of gravity with the battery and motor(s) mounted low in the chassis. It hunkers down and remains beautifully balanced and secure through sweeping bends.

But even though the car points nicely, a meaningful connection between the front tyres and your hands on the steering wheel is MIA. 

The physical brakes are vented discs at the front and solid rotors at the rear, adjustable through ‘Normal’ and ‘Sport’ settings, and they’re nice and progressive.

However, there’s more fun to be had with the regenerative braking, adjustable through three levels (‘Strong’, ‘Medium’, ‘Soft’) via steering wheel-mounted paddle shifters.

Move to the highest setting and you’re in ‘i-Pedal’ mode which means for the majority of the time easing off the accelerator is all that’s required to wash off speed before coming to a reasonably prompt halt.

In terms of ergonomics, the simple dash layout works well thanks to a sensible mix of digital and physical controls, the head-up display is crystal clear, and the big screens for media and instrumentation are hard to fault.

A word of warning, though. An over-speed chime fires four times when you even marginally exceed the detected limit. It quickly becomes intensely annoying, the saviour being an off button in the vehicle settings menu. Downside is it defaults to ‘on’ every time you stop and re-start the car. Ugh!

The Ioniq 6 showcases the latest version of Hyundai’s ‘SmartSense’ active safety suite - Everything from front and rear auto emergency braking (AEB) to a bunch of assists, including lane change, blind spot, rear cross-traffic, and heaps more. No surprise it’s scored a maximum five-star ANCAP rating.

The airbag count runs to seven - dual front for the driver & passenger), front side (covering the thorax and pelvis), full-length side curtains and a front centre/side bag to minimise head clash injuries in a side impact.

There are three top-tether points and two ISOFIX anchors for baby capsules and child seats across the rear row.

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.

Hyundai covers the Ioniq with a five-year, unlimited km warranty, with eight-year, 160,000km protection for the high-voltage battery. Both are industry standard these days.

There’s a lifetime servicing plan with maintenance intervals set at an impressive two years/30,000km. 

At this stage cost is $560 a throw, which is pretty handy when you consider the lengthy service intervals. 

A ‘Premium Roadside Support Plan’ is complimentary for the first 12 months and renewed annually while the vehicle is serviced by Hyundai.

Also complimentary is a ‘Sat Nav Update Plan’ which includes nine updates to be used within 10 years.
