BMW I4 vs BMW IX2

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.

The second-generation BMW X2 is leagues better than the car it replaces. It now sits nicely in BMW's line-up and offers genuinely tempting electric variants.

This isn't an affordable car by any means but next to rivals from Mercedes-Benz and Volvo, the well-equipped iX2 xDrive30 feels a complete package.

Similarly, the entry-level xDrive20i petrol is a very compelling choice with a comfortable ride and sporty drive.

We'd skip the contrived M35i unless your heart is set on going quickly in a straight line. With the thinking cap on, it's also hard to make a case for the X2 over the objectively better (and more affordable) X1. Then there's the more spacious, powerful, efficient and cheaper Tesla Model Y.

That's not really the point of this car, though. It'll never sell in as many numbers as the X1. Those who love its fastback styling will be pleasantly surprised by the new X2. It does what it says on the tin, marrying the BMW badge with a sporty drive and daring style.

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

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 entire point of the BMW X2 is to grab attention and promote conversation. The X2's new-found success comes mainly from bigger proportions - it's grown 194mm over its predecessor and 54mm longer than X1.

It's 64mm taller and sits on tracks that have been pumped by 21mm. All the changes are built into the latest iteration of BMW/Mini's transverse UKL2 platform.

The result is presence and swagger on the road for the X2. Even the base car grabs attention, while electric iX2 variants get unique closed-off grilles and a different front bumper treatment.

It's the M35i thats most eye-catching, though. A jutting lower spoiler and butch stance highlighted by horizontal kidney grille slats and quad exhaust tips. Our test car was finished with massive (and optional) 21-inch alloy wheels.

As successful as the whole package is, there are fussy elements: the boxy rear end, awkward spoiler and peculiar tail-lights. From some very specific angles there's even a hint of SsangYong Actyon to the proportions.

The iX2 and X2 aren't made to appease everyone, though, so you don't have to love it.

Inside is a different story with elegant simplicity the X2's remit. It's much like an X1 in layout with crisply integrated curved screens running the latest iDrive 'OS9'.

Apple CarPlay was faultless (wireless Android Auto is also included) yet connected navigation makes it easy to rely on BMW's in-house features.

You get 90 days free use of BMW Digital Premium, which includes the ability to download games and apps as well as more advanced connected navigation. After the trial, you'll need to pay monthly ($9.99) or annually ($109) for the services.

The X2's door pulls and handles are particularly nice to interact with, blending visual lightness with reassuring sturdiness.

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 the X2 living dangerously in the style department, it hasn't sacrificed cabin practicality – at least in the front seat.

A vertical wireless charging pad holds a phone in like a kid on a rollercoaster (important, as you'll read later, because the X2 range has some serious back-road talent) with nearby USB-C plugs for additional charge.

The door bins easily fit a one-litre camping bottle, there's good storage for small bags beneath the floating armrest (which has a very small cubby for keys or mints) and a sizeable glove box.

As you'd expect from a German-built BMW (all X2s hail from Regensburg) build quality is excellent... save for the flimsy indicator stalks. The latest oblong engage with a limp click that's a far cry from the damped thump of older BMWs, such as the E90 3 Series.

The cabin materials are pleasing to touch with quality stitching and soft padding on heavy touch areas. Geometrically patterned trim inserts add some cabin flare and look sturdy as well. 

The X2 and iX2's back seat is not as good as the BMW X1's – none of the proverbial thanks, Sherlock.

Under the sloping roof headroom will be acceptable for 175cm adults and knee room is passable. Despite sharing underpinnings between electric and combustion variants there's minimal spatial compromise.

There are ISOFIX ports and top tether anchors for all seating positions. Vents are mounted in the centre console and there is a fold-out armrest with cup holders. Doors open relatively wide for a 'coupe' as well. 

Of some concern is the X2's narrow bench; the body-work sculpted appearance of the coupe tail results in lots of shoulder room intrusion. To put it in simple terms, it's best capped at four occupants.

The boot is at least very generous, offering between 525L (iX2) and 560L (X2) of VDA space.

The load bay is long and there is no load lip to lift items over. Seats fold in a 40:20:40 configuration, growing capacity up to 1400L.

Neither the X2 or iX2 is fitted with a spare tyre, so its mobility kits for X2 owners.

The 2024 BMW X2 range spans $75,900 to $92,900 before on-road costs. Surprisingly, it's the M35i that's dearest, rather than the electric iX2 xDrive30 ($85,700).

There's no three-cylinder price leader in the X2 range as there is in the X1 and your body kit choice is M Sport, which explains why, trim-for-trim, the X2 xDrive20 $5000 dearer.

Once you've added the $3000 M Sport pack to the X1 xDrive30, though, you're only $2000 off the X2 for equivalent spec levels.

Some highlights include 'Veganza' artificial leather upholstery (in black, Oyster or Mocha), 19-inch alloy wheels, M Sport kit including adaptive dampers, 'Iconic Glow' illuminated kidney grilles, adaptive LED headlights, head-up display and 10.7-inch touchscreen with BMW's slick ninth-gen operating system – this equipment is shared with the iX2 xDrive30.

The $82,900 (before on-road costs) single-motor iX2 eDrive20 is more basic, missing adaptive cruise control, lane-trace assist, power seat adjust and front seat heating. All EV models include tyre pressure monitoring, acoustic pedestrian warning, 12-month Chargefox subscription, and Mode 2 and 3 charging cables.

Being a BMW there are options on the table. An enhancement pack comprises metallic paint, a sunroof, Harman/Kardon sound system, steering wheel heating and adjustable lumbar support with massage function for $3615 on the iX2 xDrive30 and $4700 on the X2 xDrive20.

Cleverly, BMW has priced the iX2 xDrive30 beneath the luxury car tax threshold – significantly benefiting those looking at buy via a novated lease – even with the enhancement pack and metallic paint. Something Mercedes-Benz hasn't been able to achieve with its $102,900 twin-motor EQA350 rival.

An M Sport Package Pro is available for all variants adding dark finish headlights and extended piano black exterior trim, M Compound brakes, M seatbelts and 20-inch 'style 873' alloy wheels.

That pack is gratis on the flagship M35i xDrive which benefits from a higher 233kW tune of its 2.0-litre turbo-petrol four-cylinder and a torsen limited-slip differential on its front axle.

The pictured M35i was finished in $5000 worth of matte paint, in this case Frozen Pure grey. Portimao blue is also available along with regular metallic paint ($1800).

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.

BMW's internal combustion engines are responsive and slick in the X2, while the iX2's well-calibrated electric powertrains deliver pleasingly instant pick-up.

The range kicks off with a heavily revised version of BMW's all-aluminium 'B48' 2.0-litre four-cylinder in xDrive20i tune. It produces 150kW and 300Nm, enough to hit 100km/h in 7.4 seconds from rest.

Like the xDrive20i, the M35i employs a seven-speed dual-clutch transmission driving all four wheels.

Australian M35is are more powerful than European models, developing 233kW and 400Nm for a 0-100km/h sprint in 5.4 seconds. A freer-flowing exhaust is augmented with active sounds for a fruity (if synthetic) note.

BMW offers a pair of electric powertrains with the 150kW front-drive eDrive20 and twin-motor 230kW/494Nm iX2 xDrive30.

We only sampled the more powerful one which features Hans Zimmer-composed sound scapes and an impressive turn of pace, hitting 100km/h in 5.6 seconds (claimed).

It is limited to a 180km/h top speed which may pose an issue on German Autobahns but is no trouble in Australia.

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.

Rated at 7.5L/100km (xDrive20i) and 7.8L/100km (M35i), after a 130km jaunt, the M35i's trip computer showed 9.8L/100km.

Premium 95 RON or higher is required and the fuel tank holds 54 litres.

For the iX2 xDrive30, consumption was above the WLTP rating. We saw 18.2kWh/100km on our hilly country route which would equate to 356km from a charge of the 64.8kWh lithium-ion battery battery.

The 417km WLTP driving range figure is at 15.5kWh/100km, we'd expect to get closer to the rated figures in more typical urban and suburban use cases.

Regenerative braking was quite pronounced (there are four setting: Adaptive, Low, Moderate and High) and on a descent into Hobart the xDrive30 managed to boost charge levels from 27 to 29 per cent.

As for regular charging, the iX2 will take DC electricity at 130kW, meaning 29 minutes from 10 to 80 per cent. That interval allows you to roam around 290km between charging stops on a long run.

One great aspect of both iX2 variants are their fast 22kW AC charging capability. It means the iX2 can go from flat-full in under four hours, rather than eight hours on an 11kW wallbox.

Though most owners won't have access to three-phase electricity, this suits public charging – such as at shopping centres or destinations – very well.

Another boon is BMW's inclusion of both Mode 2 and Mode 3 charging cables and a 12-month ChargeFox subscription.

Home wallbox installation isn't included in the deal (Lexus offers this with its UX300e) though BMW does offer the service at a cost for those who want it.

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.

The previous-generation X2 always felt a bit more Audi or Volkswagen than BMW in the way it went down a road.

This latest iteration has a secure, dynamic balance more in-keeping with the blue-and-white roundel and is far more impressive than its predecessor.

We spent our first leg in the performance-oriented M35i. The punchy engine, front-biased AWD and slick transmission felt just right in the sporty small SUV.

It sits 15mm lower than the other variants on differently tuned springs and adaptive dampers.

The M35i holds onto the tarmac like a limpet with minimal body roll at very high limits partly thanks to the efficiency-oriented 245/35R21 Continental Eco Contact 6 Q tyres.

Yet this comes at the cost of adjustability. With such tight rebound damping in Sport and Sport Plus modes, the M35i's body is too tied down. Even in Comfort, the M35i hopped and fidgeted over Tasmania's broken tarmac, a trait not aided by the 21-inch alloys.

We would have preferred more build-up in the steering weight, too, given the sporting intentions. That chubby wheel rim does its best to remove any sensation of feedback, too.

BMW's iDrive is mostly fantastic except when it comes to changing drive modes, which you need to do fairly regularly in the M35i.

More than just normal – or Personal here – there's configurable Sport and Efficiency modes. There's also Digital Art and other less useful options.

Thankfully, the xDrive20 is much sweeter. Even optioned up with the 20-inch alloy wheels the ride is a lot more agreeable and well-suited to Tasmania's lumpy roads.

All the damper modes were usable with Sport providing welcome extra support without being too strict. Turning into corners felt more natural in the xDrive20 thanks to a bit more body roll which helps communicate grip levels.

The xDrive20i did feel low on grunt after the M35i and iX2 xDrive30 but that was only in a direct comparison - grunt levels were plenty once accustomed. We did miss the M35i's front limited-slip differential on loose surfaces, but it wasn't a deal breaker.

Seeing that the iX2 xDrive30's kerb weight was 325kg higher than the M35i (2020kg) set alarm bells going initially. That's a lot of extra weight for a 'small SUV' to be carrying around, and is beyond a Tesla Model Y Long Range (1979kg).

The iX2 uses the same kinematics and suspension components as the petrol cars but in completely retuned states. Encouragingly, the result is rather excellent.

You do notices the weight when pushing through patchily surfaced corners. The iX2 bobbles and hops occasionally as you approach the damper's limits, but to their credit they never gave up.

That light steering – which is frustrating in the M35i – aids to disguise the xDrive30's extra mass, too. As all X2's are front-biased AWD models, they never quite reach the dynamic heights of BMW's Cluster Architecture models.

Still, grunt is prodigious and, although it's officially slower than the M35i, the xDrive30's rolling response is predictably excellent. BMW has done a great job calibrating the regenerative braking, too.

I found Moderate was my preference, and because the brake pedal blends caliper and regenerative forces you lose precious little range from not having it jacked all the way up.

The iX2 is quiet inside, too. There's almost no wind intrusion and tyre roar is kept to a bare minimum inside, especially impressive given that the M35i sends quite some road noise into the cabin.

Returning through Hobart's outer suburbs, we notice some shortcomings. The iX2's high bonnet, low-set seating position and letterbox rear glass with protruding rear lip spoiler mean visibility is compromised. The X1 doesn't suffer from such issues.

That's the cost of visual flare and the excellent 360-degree camera and head-up display help to alleviate guesswork and keep eyes on the road.

The M35i didn't feel the most complete on the road. If you're chasing a sporty coupe statement at this kind of price, the BMW 230i coupe is a great driver's car.

Instead, you're better to spend money on either the xDrive20i or iX2 xDrive30 with some choice options and enjoy a slick coupe SUV driving experience.

The BMW X2 and iX2 are yet to be rated by ANCAP or Euro NCAP.

The X1 and its electric cousin scored five star ratings in 2022 under a less stringent set of tests.

Standard safety equipment includes seven airbags, frontal AEB with day/night pedestrian and cyclist detection, blind-spot monitoring, adaptive cruise control, speed sign detection, lane-departure warning, lane-keep assist and driver attention monitoring.

Systems such as anti-lock brakes, electronic bake force distribution and electronic stability control are all standard.

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.

Since 2022, BMW has backed all of its cars with a five-year/unlimited kilometre warranty.

You’ll need to service the iX2 ands X2 based on condition, rather than kilometres traveled. The multimedia system will prompt you when it's time to visit a workshop. 

You can pay upfront for service plans with BMW: a five-year servicing package will cost you $3171 for the petrol X2s, while the iX2 is $2186 for six years.
