BMW I4 vs Citroen C3 Aircross

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.

It's a good car, no question. Individuality is key to Citroen's brand appeal and you get that, too. A comfortable cabin, plush ride and hot damn, it's way too expensive, which is a crying shame. You could argue - as Citroen's product planners probably have - that it doesn't help to offer one in the mid-$20K mark because it won't make much money because so few people will buy it. Drop it at a premium, only lose a few opportunistic buyers but make more money per unit with committed fans? Why not, I guess?

Like most French cars, I'm glad it exists for weird French car fans like me to consider.

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.

As you might imagine, it's an individual design. Lots of Cactus cues, like the roof rails, bluff front end and stacked headlights Hyundai, uh, appropriated for the Kona. Curiously, no 'airbumps' along the side despite the C3 hatch having them...

The 17-inch wheels somehow look tiddly given the airspace over the wheels and I can report that black is not really this car's colour, even with the contrasting white roof and weird Mazda 121 Shades special edition venetian blind treatment on the quarter window. Bit of an '80s throwback there for you.

Lots more Cactus inside though, starting with the brilliant front seats, squared-off steering wheel and funky air vents. The little tray on top of the glove box is good, but it isn't rubber-lined, so that's annoying.

The Top Gun handbrake is hilarious but apart from the texturing of the fabric on the seats, it's a tad dark below the windowline. 

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.

Even for a little car, the Aircross could do better. The lack of a proper cupholder provision for the car - a solitary spot at the rear of the centre console - is mildly baffling until you remember that this car is from France. The French hate a cupholder but, obviously, you can fit wine bottles in the doors.

It's worth repeating just how comfortable and supportive the front seats are on any given journey. Broad but supportive and somehow perfectly sprung, I would cheerfully rip out most other front seats and replace them with these.

The rear seats are less of these things and anyone who forces anyone to use the middle seat should be ashamed of themselves. The headroom is good back there, though.

The boot is a big one for the size of the car, swallowing 410 litres and expanding to 1289 litres with both rear seat sections folded.

A perennial Citroen problem is the price - at $32,990, the tiny SUV is doing battle with cars that are really a size up, coming in closer in size to the Venue than, say, the ASX.

That Yaris Hybrid price (we're all still reeling from that number) scores you a 17-inch alloys, a six-speaker stereo, climate control, front camera, reversing camera, keyless entry and start, front and rear parking sensors, cruise control, sat nav, halogen headlights (yep, you read that right), head-up display, leather wheel and shifter, auto parking, auto wipers and headlights, wireless charging pad and a space-saver spare.

The central touchscreen is annoying in that there are almost no hardware switches for functions like climate control. The software is a bit on the slow side, too, but you do get Android Auto and Apple CarPlay. The stereo is fine.

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.

One of the great engines in mass-produced road cars today has found its way under the bonnet of the Aircross. Peugeot-Citroen's 1.2-litre three-cylinder turbo is a cracking engine, serving up 81kW/205Nm through a six-speed Aisin-sourced auto to the front wheels.

While the 11.8-second dash to 100km/h is, uh, leisurely, the torque figure means that on the move it's not as sluggish as that number or its 1200kg kerb weight would suggest.

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.

Citroen claims a handy 6.6L/100km on the combined cycle and my week with the fizzy Frenchie included a trip over the hills and far away as well as a lot of suburban running. 

The digital display on the dashboard read 7.3L/100km, which isn't bad going without stop-start. It does require 95 RON premium fuel, though.

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.

French cars have a very specific audience in this country, which includes weirdos like me. I've owned Peugeots and Renaults and loved every second of it.

Top of my list after my darling baby boy wrote off our family car (which was bought for him to drive), the Cactus was close to the top of the list. This fandom isn't blind, though - I know what I'm getting myself into having to dispassionately assess their faults and foibles as well as their triumphs and tangible benefits.

If I'm being honest - and it's just you and I here - I didn't think I'd like the C3 Aircross, there was just something about its SUV pretensions. I can't say the looks grabbed me and the inexplicable exclusion of the airbumps made me irrationally cross.

But once you slip behind that square-ish wheel into the comfortable embrace of those excellent seats, you forget the aesthetics (which did grow on me, even in black). 

The 1.2 turbo is, as ever, eager to please and well-matched to the six-speed auto. The two work well together to get you moving, although the engine is the noisiest installation I can remember. In the Peugeot 308, it's virtually silent.

On the move, the lovely ride also impresses, soaking up the bumps (except those aggressive rubber speed humps in shopping centre car parks) while keeping body roll to an acceptable minimum.

It's perfectly fine in the suburbs, even with its limited power. Breaking into traffic can be a bit of a moment, but there are slower cars about.

Where the Aircross is really good is out on the freeway. It's quiet for such a small car and that torque figure makes joining the M4 freeway (west out of Sydney) fine, and it cheerfully kept up on the climb up the Blue Mountains and the brakes and transmission were great down the other side.

Citroen is unashamedly about comfort over handling, but the trade-off for the comfort is pretty good in that it still handles despite a plush ride and being up on stilts.

Along with six airbags, ABS, stability and traction controls, the Aircross has low-speed AEB (up to 30km/h), blind-spot monitoring, lane departure warning, driver attention monitoring and speed sign recognition.

Three top tether anchors and two ISOFIX points complete the picture with a five-star Euro NCAP rating dating back to 2017. There is no corresponding ANCAP score, despite the agreement between the two agencies.

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.

Citroen offers a class-competitive five-year/unlimited kilometre warranty with a five year service plan if you want to pre-pay.

That plan costs a stiff $2727 for your five visits (or every 12 months/15,000km). That's nearly three times what you'll pay for a C-HR or about $400 more than a Mazda CX-3.
