BMW I4 vs BMW IX

What's the difference?

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.

BMW’s iX M60 isn’t just the brand’s flagship all-electric SUV, it’s a statement that the electric future is here and it doesn’t have to be boring.

Pricing aside, the top-spec iX serves up practical space and prodigious performance in a package that is punctuated with panache.

The sizeable battery also allays any concerns over range, while the cabin’s appointments and fit and finish are definitely befitting of a BMW.

It’s not designed to be for everyone, and that’s okay, too, because the small customer base willing to part with around $230,000 for an electric SUV in 2022 will find a lot to like about the iX.

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.

Close your eyes and ask your eight-year-old self what an electric BMW SUV would look like, and chances are something like the iX will come to mind.

Sleek and slender, but still very BMW is the best way we can describe the iX.

Of course, we cannot talk about styling on a BMW without mentioning its front grille.

With a more vertically stacked orientation, the iX’s grille has been described as ‘toothy’ or even an ‘eye sore’ by the public in the past. But honestly, we think this attention-grabbing front end suits the swagger of the M60.

The gold highlights throughout are especially baller, and the grille serves as double-duty to hide a lot of the front-facing cameras and sensors required for more of the high-tech driving features like semi-autonomous driving.

The grille is flanked by BMW’s usual quad-headlight design for a menacing appearance on the road, and we particularly like the contrasting colours and sharp lines of our grey-coloured test car.

Another cool feature is the front badge, which can be popped up and serves as an inlet for the windscreen washer jets.

In profile, the 22-inch wheels look almost too small against the huge swathes of bodywork, but BMW has done a good job in slimming down the M60 thanks to the gloss-black stripe that runs along the bottom of the doors.

Speaking of, the handles might not pop-out like some of its rivals, but the recessed handle is highlighted nicely with gold-copper accents that also run along the beltline and door mirrors.

The D-pillar is also broken up with a blacked-out section that divides the roof, also helping slim down the behemoth BMW, and up close the section is embossed with ‘iX’.

At the rear, the clamshell boot might look large and bulky, but the design is helped by the very slender tail-lights and bumper broken up with more gloss-black.

Step inside the cabin, and the iX’s aesthetics are similarly unconventional, but the interior design also follows function.

For starters, the odd-shaped steering wheel is the feature that stands out the most, but you quickly realise the flat bottom helps with entry and exit into the driver’s seat.

As an all-electric model, there is no transmission tunnel, with the footwell between the driver and front passenger easily accessible for a more open-feeling cabin.

There is an armrest of course, while the area for multimedia controls is adorned with a one-piece, wood-like finish to contrast the crystal control knob. It’s a mix of technology and the natural environment, you see, much like the iX itself.

Do we love the styling of the iX M60? Much in the same way Louis Vuitton’s latest fashion range might not appeal to the masses, the iX M60 is likewise a polarising proposition.

To answer the question, yes, the iX M60 is a very stylish SUV that draws the eye and turns heads like nearly nothing else on the road – and that is exactly the point.

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.

Despite what it might look like on the outside or how it drives behind the wheel, BMW’s iX is undoubtedly a large SUV in shape.

Measuring nearly five metres long, and featuring a 1967mm width and 1696mm height, the iX M60 is certainly a sizeable machine.

However, it is the three-metre long wheelbase that is the most important measurement here, as it enables a vast and expansive interior space fit for the family.

The front passengers have ample room to get comfortable, and like we said in the design section of the review, there is nothing dividing the footwells of occupants up front.

This makes it the perfect place to park a backpack, handbag or even nappy bag when on the go, and means the front passenger doesn’t lose out on any legroom.

Even the armrest affords storage solutions for all the little things you might have you in pockets, while a wireless smartphone charger means you always have somewhere to place your device.

The front seats, finished in a quilted leather, might look plain, but are wonderfully supportive – even when the speedo climbs and you're carving up corners.

And in the rear, the story is largely the same, with seats that look and feel great and plenty of room for passengers to get comfortable.

My 163cm frame had no problems with leg-, head- or shoulder-room, but the base middle seat is raised a little.

We’ll also call out the great way BMW has hidden the ISOFIX mounting points for child seats, which is hidden by a flap that can be raised or lowered depending on what is needed.

It’s an elegant solution to something that can be an eyesore in other models, and shows the lengths BMW has gone to for the little details.

There is also a fold-down armrest for passengers back there, while the back of the front seats feature two USB-C charging ports, map pockets and spots to insert entertainment screens. 

Open the clamshell boot and there is a cavity that will swallow 500 litres of volume, plenty for a small family like ours, with the charging cables hidden neatly under the floor.

The boot floor is very long, too, meaning large objects will easily fit into the rear, while the 40/20/40 rear seats can be folded down to increase carrying capacity to 1750L.

To put that into perspective, something like the Ford Ranger is rated for more than 1200L in its tray, and while we would never condone the use of an iX to carry worksite tools, it does make carrying a surfboard or Ikea furniture that much easier.

However, it's worth pointing out that there is no front trunk in the iX, as there are electric motor and mechanical bits found in there. 

It’s just a shame that in a car of this size, BMW has not managed to position things with room left for a bit of usable space under the bonnet.

The 2023 BMW iX is available in four flavours, with the entry-level xDrive40 variant coming in at $135,900, before on-road costs.

The same powertrain is also available in Sport trim for $149,900, while a higher-output xDrive50 Sport sits at $174,900.

However, the top dog of the iX range is the M60, priced at a substantial $222,900.

As you can probably tell by the M badging, the iX M60 has more of a performance bent than its more affordable siblings, but it still commands a nearly $90,000 premium over the entry-level BMW electric SUV.

You are also getting a long list of equipment for the spend, though, with standard equipment including keyless entry, push-button start, heated and cooled front seats, a head-up display, and four-zone climate control – all things expected of a luxury model like the BMW iX.

The over-the-top extras you get on the M60 however, include soft-close doors, 22-inch alloy wheels and an electrochromic glass roof which can change its opacity by sending electricity through the middle layer of film. How high tech!

We also like that the iX can use the front-facing camera as a dashcam so you do not have an unsightly camera with long cables attached to the windscreen.

The iX M60 also features a curved 12.3-inch digital instrument cluster and massive 14.9-inch multimedia touchscreen with the latest 'iDrive 8' software.

Look, there’s no denying the iX M60 is a pricey vehicle, especially when stacked up against the Audi e-tron S ($173,900) and Jaguar I-Pace HSE ($160,217), but the BMW does kick it up a notch in performance compared to its perceived rivals.

Tesla’s upcoming Model X Plaid will no doubt have something to say about that, but pricing and timing for that model is yet to be revealed. For reference, the last Model X offered in Australia was in 2020, and the top-spec Performance variant was priced at $177,375.

So, does the BMW iX M60 represent good value for money? Not really. But buying a brand-new iPhone whatever on the day it launches is also not good value for money.

Early adopters and people who appreciate having the very latest in technology will always be asked to pay a premium.

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.

A large part of why the iX M60 is so much more expensive than its siblings, is because of its powertrain.

With two electric motors spinning all four wheels, the iX M60 makes a staggering 455kW of power and (are you sitting down?) 1100Nm of torque.

This means the iX M60 can accelerate from 0-100km/h in just 3.8 seconds. Not bad for a 2.5-tonne SUV, and it puts many petrol-powered rivals to shame.

This also makes it much more potent than the xDrive40 (240kW/630Nm) and xDrive50 (285kW/765Nm), while also blowing away the Audi e-tron S (370kW/973Nm).

The only electric car that comes close right now in Australia is the Porsche Taycan Turbo S (560kW/1050Nm), but the Tesla Model X Plaid supposedly makes 760kW/1020Nm from three electric motors.

And while the Tesla is not yet available, the Taycan Turbo S is more than $100,000 pricier than the iX M60, and doesn’t offer the same levels of practicality.

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.

Equipped with a 112kWh battery pack, the iX M60 features 566km of driving range according to the WLTP cycle.

In reality, we saw closer to 540km of driving range on the dash readout with a full charge, but of course this is all subject to things like the level of regenerative braking you apply, ambient temperature, the driving mode chosen, air conditioning and weight.

Officially, the BMW iX M60 consumes 26.5kWh per 100km, but our week with the car saw an average of 25.6kWh/100km with driving mainly focussed on short, inner-city trips that are advantageous to an electric car.

This betters the energy consumption of models like the Taycan Turbo S, which features a combined-cycle test of 28.5kWh//100km, but is much more energy-hungry than something like a Nissan Leaf (18kWh/100km).

This figure is also very dependent on driving style and environment, but for a 2.5-tonne SUV that will ferry the family and more, consumption isn’t too bad.

Charging options include 11kW for AC and 200kW DC fast-charging – the latter of which can juice the iX M60 from 10-80- per cent capacity in just 35 minutes, if you can find a compatible outlet, of course.

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.

Maybe it’s just us, but as soon as we step into the driver’s seat of the iX M60, the “Gotta Go Fast” theme song for the Sonic the Hedgehog cartoon just comes to mind.

And that’s probably because this BMW all-electric SUV seems to want to do one thing... go fast.

Sure, there are various driving modes on offer, including 'Sport' and 'Efficient' (as well as 'Expressive' and 'Relax', weird names, but okay BMW), but no matter what mode you are in, there is just an eagerness and urgency in the iX.

And this feeling of immediacy isn’t just because the iX is an electric car. We’ve experienced that before in other EVs. This is because it’s an M-badged BMW.

The iX M60 is wonderfully responsive to throttle inputs, and the 1100Nm (!) available makes it almost comical getting up to speed from a freeway on-ramp.

And in day-to-day traffic situations, it feels like you’ve got cheat codes on while driving.

Waiting to turn into traffic and see a gap that you wouldn’t normally be able to squeeze into? The BMW iX M60 can do it.

How about cruising along and need to change lanes, so you nudge forward a bit for the opening in traffic? Put the foot down and in the span of half a second, the BMW iX M60 has surged forward enough to flick the indicator on.

And take the iX M60 out to some twisties and that brute force will get you to the end of the road in a time you didn’t think was possible in a 2.5-tonne large SUV.

It’s almost unfair how the instant torque makes it everything so much easier on the blacktop.

But that eagerness is a double-edged sword, as when you want things to calm down and operate the iX in the smoothest manner possible, it’s harder than you might think.

Because the throttle is so sensitive and the powertrain so potent, even the slightest twitch of the right foot can lead to a quick burst of speed that knocks you back into your seat.

Even with things dialled down to the Efficient drive mode, it didn’t do much to curb the unruly iX M60 from wanting to break free at the first moment of carelessness.

Don’t get me wrong, it never gets dangerous or unpredictable, but it’s a bit like toilet training a toddler – you’ve always got to be on top of it.

And for some, that’s fine, but for others when you’ve just had a full-on day at work and have to commute home to the family, it can get tiring. 

BMW’s iX range, including the M60, was awarded a maximum five-star safety rating from ANCAP when tested in 2021.

The adult and child occupant protection tests notched the highest results (91 and 88 per cent respectively), while the vulnerable road user score (73 per cent) and safety assist (78 per cent) examinations also yielded respectable scores.

Standard safety features include all the usual suspects such as autonomous emergency braking, lane-keep assist, rear cross-traffic alert, blind-spot monitoring, a surround-view monitor and traffic sign recognition.

However, there is no rear AEB offered on the iX, which is odd in a vehicle that offers all the bells and whistles in terms of equipment. 

Littered throughout the cabin, there are nine airbags in total, including a front centre airbag to protect against passengers colliding in the event of an accident, as well as second-row chest and head cushioning units.

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.

Like all new BMWs, the iX now comes with a five-year/unlimited kilometre warranty with roadside assist over that period.

BMW held out at three years/unlimited km long after competitors had moved to five years. But this finally matches the assurance periods offered by premium rivals Audi, Genesis, Jaguar, Lexus, and Mercedes-Benz, and is up two years from the BMW warranty offered just earlier this year.

The iX uses BMW’s 'Condition Based Servicing' system, which means the vehicle will notify owners of when it needs maintenance, therefore there aren’t any scheduled servicing intervals.

However, services are bundled into four- and six-year plans, priced at $1520 and $2195 respectively. An annual average of $380 for the former, and $367 for the latter, is competitive in this part of the market.
