Hyundai Ioniq 6 vs BMW I4

What's the difference?

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.

If you’re intimidated by the electric future, don't be, because BMW’s i4 is just as good as any non-M sedan BMW offers right now.

The i4 delivers all the things you love about a 3 Series, engaging driving dynamics, a well-appointed interior and comfortable ride, but its all-electric powertrain means you’ll never have to stop at a servo again.

With a large battery on board, the i4 also serves up a decent driving range that should put anxiety-prone EV drivers at ease.

That is, of course, if you can get onboard with the looks.

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. 

If the i4 looks familiar, that’s because it is based on the 4 Series Gran Coupe that entered showrooms last year.

This means a four-door liftback body style with a sloping roofline, athletic proportions and sizing close to the Tesla Model 3 and Polestar 2.

Let’s get it out of the way early and talk about the elephant in the room, the oversized front grille.

Say whatever you want about it, there’s no denying it gives the i4 a unique and head-turning look, and in my opinion, it’s not too bad.

In the flesh, it really isn’t as big as the press photos have made it out to be, and with the front numberplate to split it up, it does start to look a bit more like a traditional grille.

In profile, the 19-inch wheels fill out the arches well, and hide the massive brakes that add to the i4’s sporty appearance.

I particularly like the almost flush door handles that look futuristic, but aren’t as pretentious as those retractable handles you see on Teslas and Range Rovers.

Slim tail-lights and a chunky bumper inform the styling of the i4’s rear, but we’re really not a fan of a rear diffuser that keeps the exhaust cut-outs.

It makes sense on a model like the 4 Series Gran Coupe, but it just looks look rather odd on an all-electric model like the i4.

While the outside of the i4 might be all about that big grille, the inside is all about big screens, two of them in fact.

The instrumentation and multimedia screens dominate the experience inside, but BMW has also included physical buttons on the steering wheel and centre stack, as well as a rotary control knob, to make navigating the menus that much easier.

The connected screens differentiate the i4 from its 4 Series Gran Coupe relative, and make the cabin feel futuristic and befitting of the all-electric powertrain.

Overall, the i4’s styling might not be to everyone’s tastes, but BMW definitely gets credit for being bold in its aesthetic choices.

Would have been nice to see BMW’s designers go a bit further in differentiating the i4 from its 4 Series Gran Coupe cousin, but there's no denying the head-turning appeal of this all-electric sedan.

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.

As a premium mid-sized sedan, the BMW i4 offers up enough storage and space for most, but keep in mind there are limitations.

From the driver’s seat, everything is well placed and the electronically adjustable seats offer plenty of adjustability to get comfy for long road trips.

Storage options include an central cubby, glove box, two cupholders and small door pockets that just about fit a bottle, but the design means it rattles around a little.

Speaking of fiddly, between this car, and the weird plastic cowl thing found in the Z4 and 1 Series, BMW needs to be called out for some of the most annoying wireless smartphone charger designs.

This one is tucked all the way under a retractable lid, and is barely wide enough to fit some flagship-sized phones.

However, we will give BMW huge props for its iDrive8 multimedia system, which is displayed on a huge 14.9-inch screen.

The menus are clear, concise and intuitive, while the software is buttery smooth and responsive. It feels snappier than some phones we’ve used in the past.

Credit too for not making all inputs touch, as there is a rotary control knob and voice command capability available.

In the second row, things are a little more cramped, but at 183cm tall I can fit in the outboard seats with tight headroom.

There’s enough leg and shoulder-room, too, and passengers can make use of the climate controls, USB-C charging ports and a fold-down-centre armrest with two cupholders.

Opening the boot reveals 470 litres of volume, but fold the rear seats down and that pace swells to 1290L.

Loading large and bulky items is made much easier thanks to the liftback design, and it’s important to note i4 buyers aren't penalised in terms of practicality as the i4 and 4 Series Gran Coupe share the same boot capacity.

However, the charging cables can get in the way, as there isn’t any dedicated space for them.

The charging point is also in an annoying spot, in the right-rear fender where the petrol cap would be.

It means that you always have to reverse into charging spots, and it can be tricky to manoeuvre the i4 into just the right position to get the charging cable to reach.

The Nissan Leaf's front centre charging port, or the dual charging ports available on the left and right fenders in the Audi e-tron or Porsche Taycan are preferable.

With a name like i4, you might be mistaken for thinking this is the sequel to the cute and quirky i3 hatchback released back in 2014.

But sorry duology fans, it isn’t.

Based on the same platform as the ever-popular 3 Series, the i4 is essentially an all-electric version of BMW’s 4 Series Gran Coupe.

And sadly, in 2022 an all-electric powertrain means a price premium.

The i4 kicks off at $99,900, before on-road costs, for this eDrive40 grade - $16,000 more expensive than the comparable 430i Gran Coupe.

Standard equipment includes 19-inch wheels, LED headlights, keyless entry, push-button start, 12.3-inch digital instrument cluster, head-up display, wireless smartphone charging, sports seats, three-zone climate control, interior ambient lighting and a powered tailgate.

Handling multimedia duties is a humungous 14.9-inch touchscreen display, powered by BMW’s latest 'iDrive8' software with features including satellite navigation, wireless Apple CarPlay and Android Auto support, a 10-speaker sound system and digital radio.

Stepping up to the M50 version adds laser headlights, a rear spoiler, sunroof, 16-speaker sound system, metallic paint and heated front seats, but also moves the asking price to $124,900, or $9000 pricier than that M440i Gran Coupe.

Of course, the i4 M50 also scores a dual-motor, all-wheel drive set-up and more potent performance, but we’ll go into more detail about that a little later on.

Is $100,000 too much to pay for an electric mid-sized sedan? Well, the most expensive versions of the Polestar 2 and Tesla Model 3 are much more affordable than this base i4, but then again, neither of those are wearing a BMW badge.

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.

If there’s one thing BMW knows how to do well, it’s building a sports sedan like no other. And that holds true for its EVs.

Powering this i4 eDrive40 is a single electric motor that produces 250kW/430Nm, which beats the outputs of even the 330i and 430i Gran Coupe.

With drive sent to the rear wheels, the i4 eDrive40 can accelerate from 0-100km/h in just 5.7 seconds, beating out the aforementioned 330i and 430i models.

For those that want a bit more pep, the top-spec M50 grade’s dual-motor set-up punches out 400kW/795Nm for a lightning quick 3.9s 0-100km/h run.

Compared with its petrol-powered 4 Series Gran Coupe counterpart, the i4 certainly puts up respectable figures, while offering more than a performance match for the Polestar 2 and Tesla Model 3.

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.

With an 84kWh battery the official range on this i4 eDrive40 is pegged at 590km when tested to WLTP standards.

However, when fully charged, our test car's range readout was around 390km.

But keep in mind EVs aren’t as effective in cold weather, and the mercury was showing only three degrees on most days during this freezing Irish winter.

Luckily then, BMW has included DC fast-charging capabilities in the i4 as standard, with its 210kW CCS plug able to take the battery from 10 to 80 per cent in around half an hour.

BMW has included DC fast-charging capabilities in the i4 as standard, with its 210kW CCS plug able to take the battery from 10 to 80 per cent in around half an hour.

Using an 11kW AC charger however, will require 8.5 hours for a full charge.

In a week with the car, I averaged an energy consumption rating of 23.4kWh per 100km, almost matching the official figure of 22.2kWh/100km.

My driving included several long-distance trips on the freeway, however, an environment in which an electric vehicle does not excel.

Worth noting the heavier and more energy-hungry M50’s official driving range drops to 510km, but we’re yet to test its real-world figures.

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!

If you came here just to find out whether BMW has succeeded in transplanting its signature sports sedan characteristics into the all-electric i4, the answer is, yes.

The best thing I can say about the i4 is that, aside from the way power is delivered and the lack of engine and exhaust noise, it feels just like a 3 or a 4 Series.

Steering is sharp and responsive, throttle and brake inputs are immediate, making this rear-drive i4 a delight to drive enthusiastically.

The staggered Michelin Pilot Sport 4 tyres and massive brakes obviously help in this regard, and look, it’s not as sharp as the Porsche Taycan, still the sharpest electric vehicle we’ve driven to date, but the driving experience in this i4 is comparable to the excellent 3 Series.

But I’m not in love with the fake sound piped into the cabin when in 'Sport' mode. It sounds weirdly low-rent and I much prefer to accelerate to triple digit speeds in serene, near-silence.

Switch things up to 'Comfort' mode, and the i4 makes for a surprisingly relaxed drive.

The steering gets bit a looser and the adaptive dampers ease off a little, soaking up bumps and road imperfections with minimal affect to occupants.

Pair this with the nearly-silent electric powertrain, and well, our little one in the back seat has fallen asleep on more than one occasion in my time with the car

You can also adjust the level of regenerative braking in the i4 and operate it with one pedal like in the Nissan Leaf and Hyundai Ioniq 5.

This is a more efficient way to drive an EV as it forces you to look ahead and be careful with your throttle inputs.

One-pedal driving might not be for everyone, but it’s nice to have the option there.

BMW’s i4 is yet to be tested by ANCAP or Euro NCAP, so at the time of publication, doesn’t wear an official crash test rating.

Neither does the closely-related 4 Series Gran Coupe, but the 4 Series Coupe, launched in 2019, received a maximum five-star assessment.

It is unclear how much the changes in body style and powertrain affect the safety of occupants, but the i4 comes with long list of advanced safety features.

Specifically, autonomous emergency braking, lane-keep assist, adaptive cruise control, traffic sign recognition, high-beam assist, a surround-view camera, parking assist, blind-spot monitoring and rear cross-traffic alert are all included at no extra cost.

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.

Like all BMWs sold in Australia, the i4 comes with a three-year/unlimited kilometre warranty with roadside assist over that period.

This falls short of the now-standard five-year assurance periods offered by premium rivals Audi, Genesis, Jaguar, Lexus and Mercedes-Benz.

Scheduled servicing intervals for the i4 are every 20,000km/24 months, at least in overseas materials.

Australian intervals are yet to be confirmed, but BMW is offering service price plans covering four- and six-year periods in 'Basic' and 'Plus' forms.

The Basic plan for four and six years is set at $1240 and $1765 respectively, while the Plus package is $4805 and $5500.
